Abstract: A drive train for a pulsed feed wheel has an offset cam on a continuously rotating drive shaft. The cam acts against a pendulum which rocks the input of a one-way clutch. A support arm attached to the output of the clutch terminates in a planetary gear. The planetary gear meshes with two sun gears one of which is fixed against rotation and the other of which is keyed to the output shaft. The planetary gear and sun gears are harmonic gears. Each revolution of the drive shaft pulses the output shaft through a small fraction of one revolution.

Abstract: A simple stepless variable transmission in which rotation of an input shaft (10) is translated into circular motion of an input stage arm (16) which is then converted into periodic rotation of an intermediate linkage (20) around a center of rotation that is displaced from the center of circular motion of the input stage arm (16). The periodic rotation of the intermediate linkage (20) drives an output stage arm (30) into periodic circular motion about a center that is displaced from the center of rotation of the intermediate linkage (20). An overrunning clutch (36) then transmits the useful portion of the periodic circular motion to an output shaft (37). Simultaneously controllably varying the distances between the centers of motion for the input stage arm (16), the intermediate linkage (20) and the output stage arm (30) controllably varies the ratio of the transmission.

Abstract: An oscillating rachet style continuously or infinitely variable transmission is disclosed herein, that is, one which, in its operation, relies on a plurality of different successive intermediate rotations that vary in speed and direction in accordance with their own respective oscillatory waveform, each waveform being out of phase with one another in a predetermined way. These intermediate rotations are used to convert the rotational input to a plurality of uni-direction output rotations, without the aid of any over-running clutches. These later outputs vary in speed in accordance with their own respective waveforms and are used to produce a modified rotational output.

Abstract: A continuously variable transmission includes a power input driving a sun gear which in turn drives a plurality of planetary gears. Within each planetary gear is mounted an over-rolling clutch. The planet gear is free to rotate about its raceway in one direction and is locked from rotation in the opposite direction. The shaft mountings for each planetary gear are suitably journalled in a carrier ring rotatably mounted within the housing.

The eccentric system is continuously positionable so as to increase the rotation of the input sun gear from a one-to-one ratio up to the maximum designed output.

Abstract: The drive mechanism for a paper tape punch and reader assembly utilizes tape drive assemblies which move the paper tape in response to the application of continuous periodic motion and control signals. The periodic motion serves to oscillate a rocker plate between first and second limits and the control signls serve to selectively engage and disengage a detent which effects coupling between the drive shaft and the source of periodic motion.

A circular body is adjustably movable with respect to the pulley plate and is arranged to engage the race of a ball bearing assembly which further comprises balls and a retaining ring. The connecting link has a circular opening which provides a snug fit to the exterior of the retaining ring.

The transmission device can steplessly change the rotational ratio of a wheel to a drive sprocket by changing the oscillation angle of rachet arms which are radially disposed on the periphery of a disk fixed to a shaft for said sprocket. The transmission device is characterized in that said rachet arms incorporated with respective crank arms are pivoted to said sprocket in positions equally distributed on a coaxial circle, and one end of each crank arm constitutes a guide pin, said guide pin being engaged in an annular groove which is coaxially provided in a rotatable bearing race the eccentricity of which can be changed.

Abstract: A vehicular drive system is presented which couples an infinitely variable automatic transmission to a constant speed electric motor. The drive system utilizes a battery powered DC motor having a no-load to full-load speed variation of less than 10 percent. The motor drives the input shaft of the transmission. The output of the transmission is coupled to drive the vehicle axle. Adjustment of the eccentricity of a cam plate within the transmission controls the speed and torque ratio between input and output shafts of the transmission. Eccentricity is varied as a function of tension on a spring in opposition to the forces developed on the cam plate by the transmitted torque. Spring tension is controlled by the pressure applied to an operator actuated accelerator pedal. The more the accelerator pedal is depressed, the greater will be vehicle acceleration and/or the steeper the hill that can be climbed.

Abstract: The invention achieves a method and a device for providing infinitely variable adjustment to the throw of an eccentric from zero to a maximum while the eccentric is permitted to continuously travel in angular motion. This is achieved by two juxtaposed and eccentric members mounted on a drive shaft, one (the outer) overriding, the other (the inner). The eccentric members may be relatively positioned by a control shaft, which extends coaxially through the drive shaft, and gearingly mates with the outer eccentric member. The outer surface of the outer eccentric can be arranged (by relatively positioning the outer and inner eccentric members) to trace the loci of points of a circle, whereupon no reciprocation takes place, or of a family of ellipses of varying eccentricity, whereby reciprocation is achieved in correspondence to the relative eccentricity in the path of travel of the outer surface.
