[0001]The present invention relates to display devices and, more particularly, to a
display device of a vehicle.
BACKGROUND
[0002]During operation of a vehicle, various operating parameters change. It is
important that such operating parameters and changes in the operating parameters of the vehicle are communicated to a rider of the vehicle. Therefore, vehicles are equipped with display devices, such as speedometer, tachometer or fuel indicator, to indicate about the operating parameters, and its status, of the vehicle to the rider. The operating parameters displayed by the display device may be speed, fuel level, temperature, distance or rotation per minutes, etc.
[0003] In general, such display devices comprise a meter base plate having a
graduated scale on its surface, a pointer pointing at the scale, and a casing enclosing the scale and the pointer. The display device is placed on the vehicle, so that it can be seen by the rider. However, the rider needs to carefully keep attention on the display device to assess the operating parameters, and changes occurring therein. Sometimes, this may be risky and inconvenient while driving.
[0004] To eliminate the risk of the accident/s, multiple methods have been employed
in the past, such as changing color of display panel or changing intensity of light displayed, or illuminating the pointer of the display device. However, such implementations are complex and difficult to implement. Additionally, these mechanisms are costly and employ expensive parts in the display devices.
[0005] One such prior art described in the Patent No. US 5,706,757. The US patent
discloses an indicating instrument which depicts the speed of the vehicle by lighting the pointer in the apparatus with help of a circuit board, rotating shaft, and a light emitting diode. The pointer is attached to the rotating shaft and has a light emitting diode at its base. Light emitting diode is disposed inside the rotating shaft and secured to the printed circuit board. Light emitted by the light emitting diode is collected by a light collecting portion of the pointer, reflected by a reflecting portion and illuminates the pointer. It is self-evident

that this type of structures increase the cost and complexity of the instrumentation display device. Therefore, such structures are costly and increase complexity while assembling the display device.

[00026] While the present invention is illustrated in the context of a vehicle, however,
display devices and aspects and features thereof can be used with other type of vehicles as well. The terms “vehicle”, “two wheeled vehicle” and “motorcycle” have been interchangeably used throughout the description. The term “vehicle” comprises vehicles such as motorcycles, scooters, bicycles, mopeds, scooter type vehicle, All-Terrain Vehicles (ATV) and the like.
[00027] The terms “front / forward”, “rear / rearward / back / backward”, “up / upper /
top”, “down / lower / lower ward / downward, bottom”, “left / leftward”, “right / rightward” used therein represents the directions as seen from a vehicle driver sitting astride and these directions are referred by arrows Fr, Rr, U, Lr, L, R in the Figures.
[00028] Referring to Figure 1 and 2, a vehicle (100) according to an embodiment of
the present invention is depicted. The vehicle (100) referred to herein, embodies a two wheeled vehicle (100). Alternatively, the vehicle (100) may embody any other ridden vehicles such as motorcycles, All-Terrain Vehicles (ATV) etc. without limiting the scope of the invention.
[00029] The vehicle (100) comprises one or more body parts, such as a frame (102), a
handle bar (104), a front wheel (106), a seat (108), a rear wheel (110), an engine (112), a front end assembly (114), a rear end assembly (116) and a fuel tank (118). The front end assembly (114) forms the front portion of the vehicle (100). The rear end assembly (104) forms the rear portion of the vehicle (100). The frame (102) supports the engine (112) in middle portion of the vehicle (100). In the illustrated example, the engine (112) provides necessary power required to drive the rear wheel (110) of the vehicle (100). Alternatively, the engine (112) may provide necessary power to the drive the front wheel (106), or both the front wheel (106) and the rear wheel (110) simultaneously, without limiting the scope of the invention. The rear wheel (110) is linked to the engine (112) through a transmission mechanism (not numbered).
- 7 -

[00030] The frame (102) supports the seat (108) which extends from middle portion
towards rear portion of the vehicle (100). The seat (108) provides seating for a rider and / or a passenger of the vehicle (100). The fuel tank (118) provides necessary fuel to the engine (112) to generate power within the vehicle (100). The handle bar (104) is configured to be rotated by the rider to steer the vehicle (100).
[00031] As shown in Figure 2, the front end assembly (114) further comprises a dash
assembly (120). The dash assembly (120) comprises a display device (200). The dash assembly (120) may comprise additional components such as, an LCD, a GPS, and a Graphical User Interface (GUI) etc. without limiting the scope of the invention. The display device (200), also referred to as “instrumentation display device (200),” displays information about the vehicle (100) to the rider. The information about the vehicle (100), displayed by the display device (200) includes operating parameters of the vehicle (100), such as speed. In various embodiments, the information displayed by the display device (200) includes other operating parameters of the vehicle (100), such as operating temperature, engine RPM, fuel level, etc.
[00032] As shown in Figure 3, the display device (200) comprises a face plate (202),
and an indicating member (204). The face plate (202) includes a granular scale (206), and is enclosed within a transparent cover (not illustrated). In an example, the face plate (202) has a circular configuration, however in other examples the face plate (202) may have an oval configuration, trapezoidal configuration, or any other configuration. The granular scale (206) is positioned along a peripheral edge of the face plate (202). Specifically, the granular scale (206) is positioned along the peripheral edge of the face plate on a first side (208) of the face plate (208), whereas a second side (not illustrated), is opposite to and beneath the first side (208). The transparent cover, covers the first side (208) of the face plate (202).
[00033] The granular scale (206) includes plurality of visual symbols (210), for
example numerical characters and values marked in an arc shape manner. The visual symbols (210) are indicative of a range of values within which operating parameters of the vehicle (100) may vary, during operation thereof. For example, the visual symbols (210) on the granular scale (206) may include speed values, ranging from a minimum speed to a maximum speed, within which the vehicle (100) is likely to operate. In another example, the visual symbols (210) on the granular scale (206) may include RPM (Rotations-Per-
- 8 -

Minute), ranging from a minimum RPM value to a maximum RPM value, often scaled to its 1/1000th multiple. In other examples, the visual symbols (210) on the granular scale (206) may include values of any other parameter of the vehicle (100), such as, but not limited to, fuel level, operating temperature level, and the like.
[00034] The face plate (202) of the display device (200), on which the granular scale
(206) is formed, is composed of a transparent material. In another example, the face plate (202) may be composed of a translucent or an opaque material. The face plate (202) includes an opening (212) defined at a center thereof. A rotatable shaft (214), shown in Figure 4, passes through the opening (212).
[00035] The opening (212) has a diameter bigger than outer diameter of the rotatable
shaft (214). Therefore, the rotatable shaft (214) is allowed to rotate within the opening (212), and with respect to the face plate (202). The rotation of the rotatable shaft (214), occurs based on changes in the operating parameter of the vehicle (100). Clearly, since the operating parameters of the vehicle (100) may range between a minimum value and a maximum value, the rotation of the rotatable shaft (214), is also within a range. For example, the rotatable shaft (214) of the display device (200), for indicating speed of the vehicle (100), rotates within its range, as the speed of the vehicle (100) ranges between the minimum speed to the maximum speed. The rotatable shaft (214) of such display device (200) rotates clockwise or anti-clockwise, as the speed of the vehicle (100) increases or decreases, and remains stationary at any given position when the speed of the vehicle (100) is stationary. Further, the rate at which the rotatable shaft (214) moves in clockwise or anti-clockwise direction, indicates the rate at which the operating parameters, say speed, is increasing or decreasing.
[00036] In another embodiment, the rotatable shaft (214) is allowed to move with
respect to the face plate (202). The movement of the rotatable shaft (214), occurs based on changes in the operating parameter of the vehicle (100). In such an embodiment, the rotatable shaft (214) of such display device (200) moves linearly along a horizontal plane of the face plate (202), as the speed of the vehicle (100) increases or decreases, and remains stationary at any given position when the speed of the vehicle (100) is stationary. Further, the rate at which the rotatable shaft (214) linearly moves, indicates the rate at which the operating parameters, say speed, is increasing or decreasing.
- 9 -

[00037] The vehicle (100) also includes sensors and information communicating
systems (not illustrated herein), adapted to sense and communicate current and / or changes in, operating parameters and a proportional rotational movement to the rotatable shaft (214). The sensors may include mechanical sensors or electronic sensors.
[00038] The rotatable shaft (214) is connected to the indicating member (204) at one
end thereof. Owing to such connection of the rotatable shaft (214) with the indicating member (204), the indicating member (204), also referred to as “a pointer (204),” is adapted to move as per the movement of the rotatable shaft (214). Therefore, as the rotatable shaft (214) rotates, the indicating member (214) moves through a plurality of positions on the face plate (202). In particular, the indicating member (204) includes a pointing portion (216) and a base portion (218). The pointing portion (216) is positioned towards the granular scale (206), whereas the base portion (218) is connected to the rotatable shaft (214). Therefore, with clockwise or anti clockwise movement of the rotatable shaft (214), the pointing portion (216) moves along the granular scale (206), and points at the visual symbols (210) on the granular scale (206).
[00039] For example, when the vehicle (100) is operating at a given speed, say 25
KMPH (Kilometers Per Hour, or Km/h), the pointing portion (216) of the indicating member (204) points towards the visual symbols (210) of 25 KMPH, on the granular scale (206). Likewise, when the speed of the vehicle (100) changes from a first value of operating parameter, say speed of 25 KMPH, to a second value of operating parameter, say speed of 50 KMPH, the pointing portion (216) of the indicating member (204) changes its position from pointing towards the visual symbols (210) of 25 KMPH, on the granular scale (206), to pointing towards the visual symbols (210) of 50 KMPH, on the granular scale (206).
[00040] In another embodiment of the present disclosure, the base portion (218) of the
indicating member (204), instead of the pointing portion (216) or along with the pointing portion (216), may be adapted to move along the granular scale (206), and points at the visual symbols (210) on the granular scale (206) with the movement of the rotatable shaft (214) to indicate current operating condition of the vehicle (100).
[00041] As shown in Figure 5, the display device (200) further includes a set of
conductor segments (220). The set of conductor segments (220) are provided on the face
- 10 -

plate (202). In an embodiment, the set of conductor segments (220) are removably connected to the face plate (202). In an example, the set of conductor segments (220) are positioned over the face plate (202), and below the indicating member (204). In alternative examples, the set of conductor segments (220) may be positioned below the face plate (202). In further examples, the set of conductor segments (220) may be positioned at any other part of the display device (200). Each of the set of conductor segments (220) remain stationary despite the rotation of the rotatable shaft (214) and the indicating member (204), because of the connection of the set of conductor segments (220) with the face plate (202).
[00042] The set of conductor segments (220), include a first segment (220a), a second
segment (220b), and a third segment (220c) disposed over the first side (208) of the face plate (202). Each of the first segment (220a), the second segment (220b), and the third segment (220c) have a gap (222) therebetween. The gap (222) ensures that the first segment (220a), the second segment (220b), and the third segment (220c) are not electrically coupled with one another. Each of the first segment (220a), the second segment (220b), and the third segment (220c) are connected to the face plate (202). Further, the gap (222) (best shown in Figure 5) is provided between the first segment (220a) and the second segment (220b), and also between the second segment (220b) and the third segment (220c).
[00043] As shown in Figure 5, and 6, the set of conductor segments (220) are
embodied as an arc shaped metallic conductor plate (224) having at least two discontinuous conductor segments (e.g. the first segment (220a), the second segment (220b), or the third segment (220c)). As shown in Figure 5, the conductor plate (224), also referred to as the metallic plate (224), may have a unitary structure with the discontinuity being provided by having alternative non-metallic segments (226) in between metallic segments, to act as the gap (222).
[00044] In another embodiment, the metallic plate (220) may have a unitary structure
with the discontinuity being provided by way of not providing continuous metallic material in between metallic material. In still another embodiment, as shown in Figure 6, the metallic plate (220) may have a compound structure with the discontinuity being provided by way of not providing continuous metallic material in between the metallic material. In such an embodiment, the first segment (220a), the second segment (220b), and the third segment (220c) of the metallic plate (220) may be composed of a metallic material, whereas
- 11 -

the non-metallic segments (226) may be composed of non-metallic material. In a preferred embodiment, the metallic plate (220) has three plates of metallic material (namely, the first segment (220a), the second segment (220b), and the third segment (220c)) and at least one non-metallic segments (226) provided in between two metallic material, thereby constituting two discontinued segments on the metallic plate (220). In further examples, the set of conductor segments (220) may be formed on the face plate (202), around the opening (212).
[00045] In the disclosed embodiment, there are three conductor segments in the set of
conductor segments (220), and each conductor segment corresponds to an operating condition or status, pertaining to an operating parameter, of the vehicle (100). Specifically, the first segment (220a) corresponds to first operating condition/status pertaining to the operating parameter of the vehicle (100), the second segment (220b) corresponds to second operating condition / status pertaining to the operating parameter of the vehicle (100), and the third segment (220c) corresponds to third operating condition / status pertaining to the operating parameter of the vehicle (100). For example, as illustrated in Figure 4, the first segment (220a) corresponds to the first operating condition/status of vehicle speed being between 0 to 45 units, the second segment (220b) corresponds to second operating condition / status of vehicle speed being more than 45 units to 70 units, and the third segment (220c) corresponds to third operating condition / status of vehicle speed being more that 70 units.
[00046] In alternative examples, there may be fewer or more number of conductor
segments, and each of the conductor segments correspond to fewer or more operating conditions pertaining to operating parameters of the vehicle (100), without deviating from the spirit of the present disclosure.
[00047] Referring to Figure 7, the display device (200) further includes a conducting
member (230). The conducting member (230) is operationally coupled to at least one of the rotatable shaft (214) and the indicating member (204). In various examples, the conducting member (230) may be connected to each of the rotatable shaft (214) and the indicating member (204). As illustrated, the conducting member (230) is connected to the rotatable shaft (214), such that the conducting member (230) moves with the movement of the rotatable shaft (214). Clearly, since the rotatable shaft (214) and the indicating member
- 12 -

(204) are connected one another, the conducting member (230) also moves with the movement thereof. In an example, the conducting member (230) is composed of a metallic material. In other examples, the conducting member (230) may be a wire composed of a conducting material.
[00048] The conducting member (230) includes a contact portion (232), adapted to be
in contact with one or more of the set of conductor segments (220). Specifically, the conducting member (230) is connected to the rotatable shaft (214) such that the conducting member (230) is beneath the indicating member (204) and may be in contact with at least one conductor segment (220), during operation of the vehicle (100). Thus, as the rotatable shaft (214) and the indicating member (204) move over the face plate (202), the contact portion (232) of the conducting member (230) comes in contact of one of the first segment (220a), the second segment (220b), and the third segment (220c). As such, the movement of the conducting member (230) is calibrated based on the movement of the indicating member (204). In an embodiment, the conducting member (230) may be fixedly connected to the indicating member (204). In an embodiment of the present invention, the indicating member (204) may itself act as the conducting member (230), and perform all, hereinafter disclosed functions of the conducting member (230). In such an embodiment, a separate conducting member (230) is omitted, as the indicating member (204) itself includes a contact portion (not illustrated) that comes in contact with one or more of the first segment (220a), the second segment (220b), and the third segment (220c).
[00049] Referring now to Figure 8, and 9, illustrating schematic views of the display
device (200), in accordance to various embodiments of the present invention. The display device (200) further includes at least one light source (250). The light source (250) may be associated with the face plate (202). In an embodiment, the light source (250) is positioned beneath the face plate (202). In an embodiment, the light source (250) includes only one light source. In an alternative embodiment, as shown in Figure 7, the light source (250) includes a multitude of light source, such as a light source (252), and a light source (254). In an embodiment, the face plate (202) of the display device (200) includes portions thereof, having selective illumination characteristics, and such portions (not illustrated) may function as the at least one light source (250).
- 13 -

[00050] In an embodiment, the at least one light source (250) includes multi-color
Light Emitting Diodes (LEDs). Each of the multi-color Light Emitting Diodes (LEDs may be adapted to provide a different colored output. In an example, the multi-color LED may be incorporated in a single LED. In alternative embodiments, the at least one light source (250) may include any other illuminating members, such as incandescent lamps. In other examples, the light source (250) may include a combination of LEDs and incandescent lamps.
[00051] The light source (250) is being adapted to operate at one or more of a plurality
of illumination modes. The illumination of the light source (250) is different in each of the plurality of modes, and may have different color, different illumination pattern, illumination intensity etc. Therefore in each of the plurality of illumination modes, the visual output of the light source (250), for a rider of the vehicle (100) is different. The plurality of illumination modes correspond to the different operating status of the vehicle (100). In an embodiment, a first illumination mode corresponds to the first operating condition/status pertaining to the operating parameter of the vehicle (100), a second illumination mode corresponds to second operating condition / status pertaining to the operating parameter of the vehicle (100), and the illumination mode corresponds to third operating condition / status pertaining to the operating parameter of the vehicle (100). In an embodiment, the first illumination mode corresponds to the first operating condition/status of vehicle speed being between 0 to 45 units, the second illumination mode corresponds to second operating condition / status of vehicle speed being more than 45 units to 70 units, and the third illumination mode corresponds to third operating condition / status of vehicle speed being more that 70 units.
[00052] For example, if the vehicle (100) is operating wherein a first operating
parameter, say speed, is at the first operating status, speed being less than 20 KMPH, the light source (250) is adapted to operate at the first of the plurality of illumination modes. The first of the plurality of illumination modes may include blue illumination of the light source (250). Likewise, when the vehicle (100) is operating wherein the first operating parameter, say speed, is at the second operating status, say speed being more than 20 KMPH and less than 60 KMPH, the light source (250) is configured to operate at second of the plurality of illumination modes. The second of the plurality of illumination modes may include red illumination of the light source (250).
- 14 -

[00053] As shown in Figure 6 and 7, the display device (200) further include a power source (260). The power source (260) may be positioned on the vehicle (100), at a location distant from the display device (200), for example underneath a seat (108) of the vehicle (100). The power source (260) may be a rechargeable battery. The power source (260) is adapted to provide electrical power to, inter alia, the light source (250) of the display device (200). The power source (260) is electrically coupled with the at least one light source (250) and each of the set of conductor segments (220).
[00054] In the disclosed embodiment, the power source (260) is electrically coupled with the light source (250). As such, the power source (260) illuminates the light source (250), when its electrical circuit is closed. The power source (260), the light source (250), the set of conductor segments (220), the rotatable shaft (214) and conducting member (230), in various positions thereof, close the electrical circuit. Each such position of the set of conductor segments (220), the rotatable shaft (214) and the conducting member (230), wherein the electrical circuit is closed, represent a different operating status of the corresponding operating condition of the vehicle (100), and therefore may cause the light source (250) to operate at one or more of the plurality of illumination modes.
[00055] As shown in Figure 8, a conducting wire (262) of the power source (260) is earthed, whereas other conducting wire (262) of the power source (260) is connected to the light source (250). Further, conductors (262) of the light source (250) are connected to each of the set of conductor segments (220). In an embodiment, a first conducting wire (264) connects the light source (250) with the first segment (220a), a second conducting wire (244) connects the light source (250) with the second segment (220b) and a third conducting wire (268) connects the light source (250) with the third segment (220c). In an embodiment, a resister (270) is provided on the first conducting wire (264) connecting the light source (250) with the first segment (220a), a resister (272) is provided on second conducting wire (244) connecting the light source (250) with the second segment (220b) and a resister (274) is provided on the third conducting wire (268) connecting the light source (250) with the third segment (220c). In an embodiment, these resisters (270, 272, and 274) are in a decreasing order of resistive values or increasing order of resistive values. For example, resistance for resister (270) may be RA= 15KΩ, resistance for resister (272) may be RB= 10KΩ and resistance for resister (274) may be RC=5KΩ; or resistance for
- 15 -

resister (270) may be RA= 3KΩ, resistance for resister (272) may be RB= 7KΩ and resistance for resister (274) may be RC=12KΩ.
[00056] The rotatable shaft (214), and the conducting member (230), while being in electrical contact with one another, are also earthed. Although in the present embodiment, the power source (260) is connected to light source (250) at one end, and other end is grounded via conducting wire (262), whereas both the rotatable shaft (214), and the conducting member (230) are also grounded, in alternative embodiments, the power source (260) may be connected to the rotatable shaft (214), and the conducting member (230) at one end, while other end may be grounded. In such an embodiment, the light source (250) may be earthed.
[00057] Referring again to Figure 8, in the disclosed embodiment, there are three conductor segments in the set of conductor segments (220), therefore there are three conductors (262) extending from the light source (250), however in other embodiments where there are fewer or more number of conductor segments, there may be a corresponding number of conductors extending from the light source (250). As shown in Figure 9, the light source (250) includes the light source (252), and a light source (254). Each of these light sources are in electrical contact with the power source (260). The light source (252) is also in electrical contact with the first segment (220a), and the light source (254) is in electrical contact with the second segment (220b).
[00058] During operation of the vehicle (100), the operating parameters may change. Various sensors (not illustrated) of the vehicle (100) sense and measure such changes in the operating parameters. For example, a vehicle speed sensor senses the speed, one of the operating parameter, of the vehicle (100). Various information communicating systems of the vehicle (100) that are interfaced with the rotatable shaft (214), provide a proportional movement to the rotatable shaft (214). For example, when it is determined that the vehicle (100) is operating at a given speed, say 25 KMPH (Kilometers Per Hour), a proportionate amount of rotational movement is transferred to the rotatable shaft (214).
[00059] Owing to the connection of the indicating member (204) and the conducting
member (230) with the rotatable shaft (214), the indicating member (204), and the conducting member (230) also rotate with the rotatable shaft (214). It may herein be noted
- 16 -

that the rotation of the rotatable shaft, and thus the indicating member (204), is calibrated with respect to the sensed operating parameter, whereby the visual symbols (210) on the granular scale (206) at which the pointing portion (216) of the indicating member (204) indicates, corresponds to the sensed operating parameter, at any given time.
[00060] Therefore, while the indicating member (204), indicates the current operating
parameter of the vehicle (100), the conducting member (230) is electrically coupled to one of the set of conductor segments (220). For example, when it is determined that the vehicle (100) is operating at a given speed, say 25 KMPH (Kilometers Per Hour), the pointing portion (216) of the indicating member (204) points towards the visual symbols (210) of 25 KMPH, on the granular scale (206). At the same time, the conducting member (230) is connected to the first segment (220a). Resultantly, the electrical circuit with the power source (260), the light source (250), the first segment (220a), the rotatable shaft (214) and the conducting member (230) is complete. With completion of such electrical circuit, the light source (250) operates at the first of the plurality of illumination modes. The first of the plurality of illumination modes may be a blue illumination of the light source (250). Alternatively, the first of the plurality of illumination modes may be an illumination of the light source (250) at a first illumination intensity. Otherwise, the first of the plurality of illumination modes may be an illumination of the light source (250) at a first illumination pattern.
[00061] Such illumination of the light source (250) may indicate to a rider that the
current status of the operating parameter of the vehicle (100) is less than a predefined higher threshold. Otherwise, such illumination of the light source (250) may indicate to the rider that the current status of the operating parameter of the vehicle (100) is safe.
[00062] Further, when it is determined that the vehicle (100) is operating at a different
speed, say 60 KMPH (Kilometers Per Hour), the pointing portion (216) of the indicating member (204) points towards the visual symbols (210) of 60 KMPH, on the granular scale (206). At the same time, the conducting member (230) is connected to the second segment (220b). Resultantly, the electrical circuit with the power source (260), the light source (250), the second segment (220b), the rotatable shaft (214) and the conducting member (230) is complete. With completion of such electrical circuit, the light source (250) operates at the second of the plurality of illumination modes. The second of the plurality of illumination modes may be a red illumination of the light source (250). ). Alternatively, the
- 17 -

second of the plurality of illumination modes may be an illumination of the light source (250) at a second illumination intensity. Otherwise, the second of the plurality of illumination modes may be an illumination of the light source (250) at a second illumination pattern.
[00063] Such illumination of the light source (250) may indicate to a rider that the
current status of the operating parameter of the vehicle (100) is higher than a predefined threshold. Otherwise, such illumination of the light source (250) may indicate to the rider that the current status of the operating parameter of the vehicle (100) is in high speed zone.
[00064] Any change in illumination mode of the light source (250), for example blue
illumination turning into red illumination, may provide a visual indication to attract attention of the rider regarding change in operating status of the operating parameter of the vehicle (100), without having to carefully look at the display device (100). The display device (100) of the present invention, in this manner, eliminates the risk while driving by precluding the need to intermittently shifting attention to the display device (100), e.g., taking the eyes of the road, to know whether the operating parameter of the vehicle (100) is within range. The display device (100) of the present invention, therefore, makes ride of the vehicle (100) convenient and safe.
[00065] While few embodiments of the present invention have been described above, it
is to be understood that the invention is not limited to the above embodiments and modifications may be appropriately made thereto within the spirit and scope of the invention.
[00066] While considerable emphasis has been placed herein on the particular features
of this invention, it will be appreciated that various modifications can be made, and that many changes can be made in the preferred embodiments without departing from the principles of the invention. These and other modifications in the nature of the invention or the preferred embodiments will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the invention and not as a limitation.
