Field of Invention
The present invention relates to hand tools and more specifically to (removable) socket drive tool and it's using method.
Background
A variety of socket tools are available in market. Simple Sockets such as Hex sockets, socket bits, Impact sockets and Special Sockets such as adjustable multisockets, Pass-through sockets, socket tools with extra gripping facility (in this case the socket does not round-off the corners of the nut/bolt head), Universal sockets, Spark plug sockets, insulated sockets, oil filters sockets and Bolt grip sockets; are available in the market. To facilitate the use the above described sockets in tight and confined spaces, socket accessories such as Wobble extension bar, Flexible extension bars, adaptors or converters, universal joints, Socket rail tracks, Retaining rings and pins and torque multipliers are available.
But to drive these different sockets basically two main methods are used 1) manual driving handles 2) Use of power tools. Manual Socket drivers available are either with ratcheting handles or Standard drive handles with fast rotating attachment.
Socket wrenches with ratcheting and non-ratcheting handles (with fast rotating attachments) are available but are fiddly, more time and more effort consuming to use. The present invention introduces a new concept tool (Rota socket handle) for driving the socket, required in tightening or un-tightening, and to easily inset or eject the loosened nut on bolt/screw.
Prior art
Patent specification number CA1208945 depicts a wrench head attachment for rotating threaded fasteners in one go, after initial untightening or for final tightening. The tool for rotating threaded fasteners, mentioned as in Patent specification number CA1208945 can be considered as relevant prior art for present invention as it partially fulfills the objective of the present invention. The apparatus named, tool for rotating threaded fasteners, as described in patent specification number CA1208945, solves the problem of how to rotate the drive member at a relatively high speed in one simple movement by forming the drive member as a drum or providing it with a reel around which a non-resilient flexible member such as wire, cable, cord or tape is wound. A simple pull exerted at the end of flexible member causes rapid rotation of drive member. Return motion of the drive member is achieved by resilient means such as coil spring wound on another reel provided on the drive member or by using a flexible member, which is also resilient i.e. a spring. Ratchet handles/ standard socket drive handles/ ratchet handles with tool for rotating threaded fasteners attachment have limitations such as

more consumption of time, more consumption of effort, use of second hand and use of fiddly methods to achieve the desired result.
Thus, there arises a need for a socket driver handle which eliminates the above stated limitations. Patent specification numbers WO1992007203, GB1338338, GB1351621 somewhat/partially relate to different components/methods used in present invention. The present invention can be considered as highly modified combination of the above mentioned patents and some further different add-on. However all the above mentioned patents do not even partially fulfill the objectives of the present invention.
Objectives of the present invention:
1. The main objective of the present invention is to facilitate easy and fast inset of nut on bolt/screw for final tightening, and easy and fast ejection of nut from bolt/screw after initial un-tightening.
2. Another objective of the present invention is to facilitate, use of only one hand to achieve the said main objective.
3. Still another objective of the present invention is to fulfill the above mentioned objectives without the use of power (i.e. a manual -hand driven tool).
4. Still another objective of the present invention is directed to a method of applying torque in case of a bit weared out threads on nut/bolt/screw; described in 3rd point of overview of method of using the Rota socket tool.
Summary:
A) A first aspect of the present invention is directed to an apparatus for initial un-tightening or final tightening along with easy ejection and insertion of nut on bolt. The apparatus comprising of Main handle, An Arm, A Gear train, A spiral spring, A pusher assembly, Central rotor (socket adapter), Main mid rotor, and Bearing mid holder. Squeezing of Main handle and Arm together, operates the pusher assembly, which in turn pushes the combination of Main mid rotor and Bearing mid holder in to Main handle, to engage Main handle and Central rotor together(EIMGAGED MODE). Central rotor has socket adapter on one side and an extended portion on other side, to which a gear (Rear rotor connector) can be attached/fastened, such that the Central rotor then acts as an output shaft for a gear train. Gear train mentioned is such, which while rotating in one direction stores energy by winding of spiral spring, but does not transfer the rotational motion to output shaft (Central rotor) as the gear train breaks by moving of a gear from its rotational center. The gear train rotates in second direction, under the effect of the resilient force of the unwounding spiral spring, and transfers the rotational motion to output shaft (Central rotor), when in disengaged mode, thus easily inserting/ejecting out the nut/bolt after initial un-tightening or for final tightening. Direction of rotation of output shaft (Central rotor) can be changed by adding a gear in the gear train by shifting a lever from one position to another. Torque can be applied to nut or bolt head in engaged mode by rotating

the main handle around the axis of the central rotor, either for initial untightening or final tightening.
B) Optionally, the pusher assembly of the Rota socket tool may actuate on screw mechanism or on cam and follower mechanism.
C) A second aspect of the present invention is directed to a method of using the device, for initial un-tightening and easy ejection and/or, to easily inset for final tightening a nut on bolt. The method comprises:
1) Engaging the nut/bolt head in the socket (removable), mounted on socket adapter of
central rotor and then pressing Arm towards main handle , till it touches the main handle
2) Applying torque to the nut/bolt head by rotating the Main handle (along with arm) in required direction, for initial un-tightening or for final tightening.
3) Releasing the arm, allowing it to move away from Main handle under the resilient force of compressed torsion spring. Releasing the arm causes to rotate the central rotor, when in disengaged mode, under the action of resilient force of unwounding spiral spring of gear assembly
D) Optionally the direction changing lever can switched in one or second active position before 1) and pressing or releasing can be done thereafter to engage or disengage the Central rotor with Main handle
Overview of, method of using, the Rota socket tool:
1 For untightening and ejecting the nut from the bolt/screw.
a) Engage the nut/bolt head in the socket (removable), mounted on the socket adapter of central rotor 3, and then press Arm 12 towards Main handle 1, till the Arm 12 completely comes in contact with the Main handle 1. Optionally, the pressing of Arm 12 towards Main handle 1 can be done before or after engaging of the socket to the nut/bolt head.
b) For applying torque to the nut/ bolt head Rotate Main handle l(along with Arm 12), in direction of untightening of nut, for initial untightening.
c) Once the nut gets a bit loose on bolt/screw, release the Arm 12 allowing it to move away from main handle l(i.e. releasing). Releasing, will eject the nut from bolt by rotating the Central rotor 3 and thus, the nut with the socket.
d) In case of long bolts use deep length sockets, and after initial untightening, repeat the process of pressing and releasing, until the nut comes out OR alternatively use the gear train with higher gear ratio for the Gear assembly of the Rota socket tool.

2 To facilitate inset on bolt/screw and then final tightening
e) Add a gear in the gear train by switching the Gear changing lever 17h to second position.
f) Then firstly, put together the nut on bolt manually by rotating for one. or more turns and then press the Arm 12 towards the main handle 1 and then engage the socket, mounted on socket adapter of Central rotor 3, to the nut/bolt head.
OR
f) Directly put in, the nut in socket, mounted in socket adapter of Central rotor 3. Then press the Arm 12 towards the Main handle 1 and then target the nut to the bolt/screw and release the Arm 12.
g) Releasing, rotates socket and Central rotor 3. Repeat the process of pressing and
releasing, till the nut reaches in a position, where it requires final tightening.
h) To apply torque, again press the Arm 12 towards Main handle 1, resulting in engaging of Central rotor 3 and Main handle 1. Then rotate the Main handle 1, in a direction of tightening of nut.
3 Incase where, after initial untightening the nut on bolt, the exemplary Rota socket tool is
unable to takeout/inset the nut from/on bolt (due to bit damaged threads) by releasing action,
repetition of manual action sequence as listed will help to eject/inset the nut from/on bolt:
a) Engaging ( by pressing Arm 12 completely towards Main handle 1, to actuate pusher assembly{FIG. 8}, resulting in pushing of Main mid rotor 5 , to engage Main handle 1 with Central rotor 3)
b) Applying torque ( by rotating Main handle 1 along with Arm 12 in required direction)
c) Releasing ( by allowing the Arm 12 to move away from Main handle 1 under the effect of resilient force of compressed Torsion spring 11, on reducing the gripping force)and again rotating ( Mani handlel and Arm 12) in reverse direction to reach the point of engaging.

Detailed Description accompanied with drawings: Engaged mode:
Pressing Arm 12 towards the Main handle 1, causes pusher assembly to push the Pusher cylinder 7, which in turn pushes the combination of Main mid rotor 5 and Bearing mid holder 4, to slide axially and move in to Main handle l,by pressing Helical spring 10 placed in-between Central rotor 3 and Main mid holder 5, thereby engaging Main handle 1 and Central rotor (socket adapter) 3 together, such that the torque can be applied to nut/bolt head by rotating the Main handle 1 in required direction. Fig. 7 shows the exemplary Rota socket tool in Engaged mode.
Pis-engaged mode :
Releasing Arm 12, allowing it to move away from Main handle 1 under the action of resilient force of Torsion spring 11, causes the Pusher cylinder 7 to descend back in pusher assembly, allowing the Helical spring 10 to push away the combination of Main mid rotor 5 and Bearing mid holder 4, to disengage the Central rotor (socket adapter) 3 from Main handle 1, such that the Central rotor 3 now can be rotated in clockwise/counter clockwise direction when/if actuated by a Spiral spring operated gear train.

The illustrative Rota socket tool has three main operations. Referring to Fig. 2 and Fig. 3 there are three main operations that will be described in detail below.
1. Pressing ( Engaging and Charging )
2. Applying Torque ( For Initial Untightening and/or for Final Tightening)
3. Releasing ( Disengaging and Imparting )
1. Pressing (Engaging and Charging)
Firstly, mounting standard sized/adjustable socket on/in socket adapter of the central rotor 3.Central rotor have either male socket adapter (shown) or female socket adapter (not shown).
Engaging:
• The Arm 12 is pressed (completely) towards the Main handle 1, rotating around the main sealer 14, on/around Supporter-moving gear 16, compressing the Torsion spring 11.
• Fig. 13 shows the exemplary Rota Socket Tool without gear assembly, actuating the pusher assembly (Fig. 8), pushing Main mid rotor 5 and Bearing mid holder 4 into Main handle 1, by pressing Arm 12 towards Main handle 1.
• Referring again to Fig. 2, the teethed part of Arm 12 meshes with, toothed pusher cylinder 8. Pressing Arm 12 towards Main handle 1 causes to rotate Toothed pusher cylinder 8. Person skilled in art will easily understand that Arm 12 and Toothed pusher cylinder 8 can be integrated to form a single part, rotating around the central longitudinal axis of Toothed pusher cylinder 8, to operate the pusher assembly (Fig. 8); without departing from the present invention.
• Pusher cylinder 7, and Toothed pusher cylinder 8 are connected through screw mechanism. Thus, rotation of Tooted pusher cylinder 8 results in axial sliding of Pusher cylinder 7, for which Spider 6 acts as frame, by providing sliding channel.
Skilled person will readily understand, that different components such as Cams and Followers can be used to form the pusher assembly, giving out the same result.
• Side face of Pusher cylinder 7 facing Main mid rotor 5, pushes the Main mid rotor 5, in
the cylindrical recess of Main mid rotor 5, provide for the same purpose.
Spline/gear teeth on outer surface of Bearing mid holder 4 always remains in contact
with the internal spline/gear teeth of cylindrical part of Main handle 1, but are free
to slide axially.
Spline/gear teeth on internal surface of main mid rotor 5 always remains in contact with the spline/gear teeth on outer surface of Central rotor 3, but are free to slide axially.
Bearing mid holder 4 and main mid rotor 5 are free to rotate relative to each other, after being assembled as one. After assembly they act as radial thrust bearing with metal balls in between races 5c (Fig. 10) and 4a (Fig. 11) of corresponding parts.

The spline/gear teeth on internal surface of cylindrical part of Main handle 1 has chamfered and filleted ends la (Fig. 12), and Main mid rotor 5 has chamfered and filleted ends 5a (Fig. 10) on outer spline/gear teeth, to facilitate easy engagement and disengagement with each other.
• On being pushed by the pusher assembly(FIG. 8), Main mid rotor 5 starts compressing down the helical springs 10 in their respective seats 5b(Fig. 10) and 3a(Fig. 9) and adjusts, by rotating through very small degrees, to slide axially to engage the Central rotor 3 with Main handle 1.
• The chamfered and filleted ends la (Fig. 12) of internal spline/gear teeth, on inner surface of cylindrical part of Main handle 1 allows easy engagement of spline/gear teeth on outer surface of Main mid rotor 5 to the spline/gear teeth on internal surface of cylindrical part of Main handle 1, with help of chamfered and filleted ends 5a (Fig. 10) of spline/gear teeth on outer surface of Main mid rotor 5.
• Fig. 4 shows two different assembled perspective views of the parts shown in Fig. 2 and Fig. 3.
• Fig. 6 and Fig. 7 shows the front view and cross -sectional view of exemplary Rota Socket Tool in Dis-engaged and Engaged mode respectively.
Charging:
• The action of pressing Arm 12 towards Main handle 1 not only engages Central rotor 3 and Main handle 1, but also does the function of charging a gear train.
• Moving gear 13 can rotate around Main sealer 14, with the help of support from Arm 12, as shown in Fig. 13.
Skilled person will readily understand that the Moving gear can be incorporated as a part of Gear assembly 17, by providing a rotating center in gear assembly, and will give out same result as that of present invention.
• Moving gear 13 has gear teeth on internal surface, which mess with the Actuating Gear 17Land rotates it.
• Wounding gear 17b wounds the spiral spring 17m, on being rotated from Actuating gear 17L. The gear train gets charged by storing energy in form of strain of wounded Spiral spring.
• The gear train does not transfer the rotational motion to output shaft (Central rotor 3) on pressing action, as the gear train breaks, by shifting of Missing gear 17c from its original rotating center to a new rotating center, in the slot provided, as shown in Fig. 5.
• Thus, the gear assembly gets charged by wounding of spiral spring.
Skilled person will readily understand that the exemplary gear assembly can be replaced by more complicated planetary, compound gear trains to gain more gear ratio.

2 Applying Torque (for initial untightening or final tightening)
• While the exemplary Rota Socket tool is in engaged and charged mode, it is ready for initial untightening/final tightening.
• Torque to nut/bolt head can be applied by rotating the Main handle 1, around the central axis of the cylindrical part of Main handle 1, in required direction.
•' Rotating the main handle 1 transfers the torque, from the internal spline/gear teeth on inner surface of cylindrical part of main handle 1, to the external spline/gear teeth on outer surface of Main mid Rotor 5, from there to internal spline/gear teeth (of Main mid rotor 5) and from there to the external spline/gear teeth on outer surface of Central rotor 3 and thus to nut/bolt head via the socket of the corresponding size.
• Once the nut gets loosened a bit on screw/bolt, it can be easily ejected/inserted from/in bolt by the releasing of Arm 12, allowing the Arm 12 to move away from Main handle 1.
• Optionally, to inset the nut on bolt/screw, by releasing the Arm 12, allowing the Arm 12 to move away from Main handle 1, would be effective only after adding a gear to the gear train, by shifting Direction changing lever 17h to second position. Then providing torque by rotating the Main handle 1, in second direction for final tightening. The arrangement of the direction changing lever is as shown in Fig. 5
3 Releasing (Disengaging and imparting)
Disengaging:
• Reducing the applied pressure on the Arm 12 allows the Arm 12 to move away from the Main handle 1, by the action of separating force of Torsion spring 11.
• Moving of Arm 12 away from Main handle 1 , rotating around the Main sealer 14 , rotates the Toothed pusher cylinder 8 of pusher assembly in second direction and thus Pusher cylinder 7 moves back in pusher assembly, allowing Main mid rotor 5 to disengage.
• Helical springs 10 placed in their respective seats 3a(Fig. 9) and 5b(Fig.lO) between Central rotor 3 and Main mid rotor 5, then pushes them away from each other, to disengage Main handle 1 from Central rotor 3. But, spline/gear teeth on outer surface of Bearing mid holder 4 are still in contact with the internal spline/gear teeth of cylindrical part of Main handle 1, which allows the assembly of Central rotor 3, Main mid rotor 5 and Rear rotor connector 9 to rotate in both the direction.
• Fig. 6 shows the front view and' cross-sectional view of exemplary Rota socket tool in disengaged mode.
Imparting:
• When the Rota socket tool comes in disengaged mode after releasing action, the
wounded spiral spring 17m, automatically starts unwounding and thus imparting the

rotational motion to Wounding gear 17b.
• Missing gear 17c moves to its original rotating center by displacing in the slot provided, by the relative motion of wounding gear and thus, completes the gear train.
• Under the resilient force of unwounding of Spiral spring 17m , gear train starts transmitting the rotational motion to Central rotor 3(output shaft) via gear on the Rear rotor connector 9 . Thus, the nut on bolt can be easily facilitated to inset for final tightening and can be easily facilitated to eject after untightening.
• Fig.14 shows, two different views of the rotating members, rotated by the action of resilient force of unwounding Spiral spring, and the spiral spring.
