Abstract: An improved wheelchair wheel and hub assembly is described that interposes reduction gearing between the handring or rotatable hand wheel and the drivewheel of the assembly. This gearing provides some mechanical advantage to users who may lack sufficient strength to propel themselves in a conventional wheelchair, especially in a home environment. A single speed assembly is described which is operated conventionally by rotating handrings either forward or rearward to produce a corresponding rotation of the drive wheel but, unlike conventional wheels, a complete revolution of the handring results in only a partial revolution of the drive wheel. In the hub of the assembly is a wheel locking mechanism which enables the wheel to be easily and positively locked for the safety of the user, preventing rotation of the wheel in either direction. Additionally, a ratcheting mechanism is incorporated into the hub design which can be engaged to allow forward rotation but prevent rearward rotation of the drive wheels.

Simple swing motion of the support bracket about the drive shaft produces an enlarged free space above the selvage unit during the looming operation, thereby allowing free transportation of heald frames necessary for the looming operation.

Abstract: A drive roll 14 carries a gear (60) that engages a reversing gear (58) driven by a planetary gear (56) on a pivot arm (50). The planetary gear (56) is driven by a sun gear (48) that rotates about the pivot axis of the pivot arm (50) and in turn is driven ultimately by a motor (30). A unidirectioal roller clutch (52) is connected between the pivot arm (50) and the sun gear (48) so as to permit relative rotation between the sun gear and the pivot arm in one direction but prevent it in the other direction.

When the sun gear (48) is driven in the other direction, on the other hand, the pivot arm (50) is caused to pivot with rotation at the sun gear (48) to bring the planetary gear (56) out of engagement with the reversing gear (58).

Abstract: A precision power gear train assembly particularly adaptable for use with vehicles having a 360.degree. rotatable turret mounted thereon. The assembly embodies novel spring and stop means to minimize backlash and to limit gear tooth disengagement of the enmeshed output pinion and ring gears of such an assembly. More specifically a pinion-ring gear assembly mounts a gear box to oscillate about an axis parallel to the pinion axis of rotation such that the tooth pressure between pinion and ring gear biases the teeth apart, increasing backlash. A preloaded spring biases the gear teeth into tight mesh to eliminate backlash until the tooth pressure force exceeds a predetermined maximum. Thereafter, further increases in the tooth pressure force separates the teeth by compression of the spring beyond its preloaded compression. A stop limits tooth separation.

A brake prevents the microscope from being manually pushed into the viewing platen. In the x and y plane movement mechanisms torque limiting clutches prevent damage to the drive mechanisms, and a slip clutch allows turning of a positioning knob without driving when the bridge reaches the end of travel.

Abstract: An input shaft of a press feed is rotated at a preselected speed and is drivingly connected to a cam that rotates with the input shaft.

The oscillating rotational movement of the output shaft is transmitted to the driven feed roll to advance the driven feed roll in contact with stock material through a preselected degree of rotation corresponding to a preselected feed length of the stock material to the press. The feed length is adjustable by changing the length of travel of the linkage mechanism with respect to the degree of rotation of the output shaft.
