Abstract: An underdrive transmission incorporates a planetary gear assembly including a sub-assembly which may be shifted manually between high and low-range modes to establish direct and reduction ratio drive. In the high-range mode, the drive path is from an input member directly through the carrier to an output member, with the gears unloaded. In the low-range mode, the sun gear is grounded to the housing through a reaction plate, and the drive path is from the input member to the ring gear and from the carrier to the output member. The sub-assembly includes a slidable shift sleeve on which are supported the sun gear, carrier and planet gears.

Abstract: A friction plate-type clutch of the over-center type and having automatic adjusting means which is designed to sense cluth engaging force and make incremental clutch adjustments when the engaging force drops below a predetermined value.

Abstract: Precise angular relationship between release means and driven means is attained in a coil spring clutch by means of a spring-positioning ring which is permanently secured to the driven hub only after being rotated into desired position.

Abstract: A gear planet carrier assembly which provides accurate alignment of multi-planet clusters of gears relative to a sun gear and a ring gear in a dense epicyclic multiple branch system of a double reduction gear system while insuring torsional and lateral stiffness. Planet carrier assembly is made of a light material to keep the overall weight and inertia of the system low.

Abstract: A torsional vibration damper assembly providing a variable torsional deflection rate having a very low initial deflection rate. The assembly utilizes a vibration damper assembly having a set of compression springs providing the torsional deflection rate for the main stage of relative angular displacement between the input and output members and an auxiliary resilient means to provide an extremely low initial torsional deflection rate; the auxiliary means comprising sets of interengaged free play splines between the barrel of the clutch hub and a separate hub flange with springs between the sets of teeth to preload the splines lightly in either the drive and/or coast directions.

Abstract: A positive acting magnetic clutch and brake assembly characterized by including a movable, magnetic member provided with two sets of detents arranged respectively on its opposing outer surfaces. The member is alternately shiftable into either a brake position, in engagement with a braking post mounted to engage one of the sets of detents, or to a drive position in which a reciprocally mounted mechanical dog is engaged with the other set of detents in a non-slip driving coupling between the magnetic member and a clutch assembly. A reciprocal mounting arrangement for the dog enables the magnetic member to be moved into driving contact with the clutch assembly before the dog becomes positively engaged with any of the detents on the magnetic member.

Abstract: The invention pertains to a pulley for belt conveyors, particularly belt conveyors used in the conveying of stones, gravel, and the like wherein the pulley structure is self-cleaning of foreign matter received within the confines of the pulley to prevent belt damage. The pulley consists of a plurality of helically disposed webs spiralled about a rotatable shaft. A plurality of webs are defined upon the shaft on each side of the pulley central region wherein at least two separate webs define a set of multiple pitch helices, and each set is spiralled about the axis of rotation in an opposite direction wherein foreign matter received between the webs is moved to the pulley ends in a self-cleaning manner. A disc is utilized at the pulley central region to which the inner ends of the web sets are affixed and the periphery of the webs is of a greater axial dimension than the web plate to increase the belt surface loading area.

Abstract: The invention relates to automobile friction clutch driven plates, and in particular to driven plates having idling vibration dampers and load vibration dampers. The friction clutch driven plate includes two concentric hub members. On one hub member is mounted a friction facing carrier capable of limited restrained angular movement about the hub axis relative to the hub members. The friction facing carrier and the other hub member have spring seatings, being hub member seatings and carrier seatings, so that springs acting between the seatings oppose relative rotational movement between the hub members. The construction of the driven plate is made compact and simplified by having the hub member seatings and carrier seatings in a common radial plane.

Abstract: A unit for remotely operating an element to different positions such as start, fast, slow and stop for a driving application such as the one herein illustrated for the engine of a lawn mower. The unit is made of plastic material being molded in two parts with a recess in the side of one part which is adapted to receive a tube forming a handle. A bolt passes through a hole in the part and through the tube to which it is securely retained when a lock nut and bolt is tightened. The unit has a slot between the two parts in which a lever is movable to advance and retract one or more control wires which operate the carburetor, brake or other element of the lawn mower.

Abstract: The circuit, which controls actuation of a clutch intermediate an electrical motor and a conveyor, is powered from a transformer which taps the power supply to the motor. The circuit contains a relay switch which is operable by a current sensor attached to the power supply line.

Abstract: A vehicle power transmission for tractors and the like having a fluid operated speed-change mechanism which comprises a plurality of rotatably mounted speed-change gears arranged on a lay shaft and a plurality of fluid actuated clutches associated with the respective speed-change gears for selectively connecting each of the gears to the lay shaft. A brake is provided which selectively brakes the lay shaft at the non-operation state of the fluid operated speed-change mechanism. The brake prevents unexpected transmission of power through the speed-change mechanism at the non-operation state of the mechanism, thereby preventing problems such as an unexpected start of the vehicle.
