Field of the Invention
The present invention relates to a Drive Lever Mechanism and more particularly the present
invention relates to a Drive Lever Mechanism in a Vibratory Tandem Compactor.
Still more particularly this present invention also relates to a Drive Lever Mechanism which
is used for changing the direction for driving and for adjusting the speed of the machine.
Furthermore, this invention of Drive Lever with Five Position Mechanical position is
performed for operating the machine from either Left or Right side.
Background of the Invention
There is a direct co-relation between the affluence and industrialization of a society and the
quantity of refuse which is generated by that society. Thus, in the industrialized nations, the
quantity of refuse which is generated is many times that was generated in a more primitive
society.
The US Patent specification no. 7404475 describes the expansion of the spring element over
a wide contact surface area against the cylindrical drive face of the drive wheel as well as
through the expansion cams of the coupling element which are able to tilt about an axis
spaced from the drive axis a force-locking engagement is produced to transfer torque from
the drive lever to the drive wheel over a wide contact surface area and therefore with low
surface area pressure. The expansion cams are preferably arranged at different radial
distances from the drive axis on the drive lever so that the expansion cams during swivel
movement of the drive lever about the drive axis complete a tilting movement whereby the
actuation levers which are connected to the spring element are expanded and the spring
element is expanded to bear against the cylindrical drive force of the drive wheel. For a play-
free contact bearing of the expansion cams against the expansion faces of the actuation levers
at least one expansion cam is designed pre tensioned wedge shaped and mounted radially
displaceable between two contra-rotating wedge faces of the expansion faces of the actuation
levers but is supported with self-locking action opposite the other expansion cam.

GB Patent No. 19855285 discloses a bidirectional manual drive known for generating a
rotational movement which starting from a zero point position of a drive lever which is able
to swivel about a drive axis follows selectively in one or other rotational direction. During
rotation of the drive lever from the neutral position contact bearing faces of circular section
shaped coupling elements bear with force locking engagement against the opposing partially
circular shaped faces of a cylindrical drive face of an output element and entrain the output
element in the circumferential direction whilst during return of the drive lever into the neutral
position the force locking engagement of the coupling elements against the cylindrical shaped
drive face is lifted so that the output element is not entrained.
According to GB Patent specification no. 19907483, for generating a rotational movement
has a housing in which are mounted a drive element, an output element which can be
angularly adjusted by actuating the drive element, and a loop spring with several windings
which are supported on the inside wall of the housing and block any torque introduced from
the output side whilst in the event of torque introduced on the drive side they trigger the
transfer of torque from the drive element to the output element. The angled ends of the loop
spring are connected to a transfer element mounted between the drive element and output
element.
Further, the said US Patent No. 7404475 states the solution according to the invention above
is that the expansion cams are mounted in different radial distances from the drive axis on a
reinforcement lever supported with swivel action on the drive lever so that the required
motion play is set up by the reinforcement lever whilst the drive lever can be attached to the
drive axis free of play and is consequently optimally centered. The connection of the
reinforcement lever to the drive lever can be arranged radially in alignment with the
expansion cams and can be provided either on the same side in relation to the drive axis as
the expansion cams or on the side of the reinforcement lever opposite the expansion cams in
relation to the drive axis.
According to the invention US Patent Specification No. 8001887, an adjustable universal
trash compactor comprising: a frame including a plurality of vertical slider support members;
a compactor driver slidingly attached to said vertical slider members with a plurality of slider

sleeves; a compactor head attached to said compactor driver; a handle mechanism coupled to
said compactor driver applying force to said compactor driver and causing it to slide
vertically along said vertical slider support members; a vertical adjustment coupling said
handle mechanism to said frame, wherein said handle mechanism can be adjustably raised
and lowered along said vertical slider support members; a utility cover over said frame;
wherein said frame can receive containers of different sizes or said compactor can be
operated with no container; and wherein said compactor head is configurable to be replaced
with compactor heads of different sizes and shapes.
