Abstract: In a deployment apparatus for extending a safety device from a school bus, the safety device is attached to a connector which is rotated about a pivot pin that is turned by a friction clutch driven by an output shaft. The safety device may be either a guard arm on a front bumper or a stop sign on a side of the school bus. The present invention is an improvement, i.e. an L-shaped bracket and a gear box are integrally molded together into a unitary structure. Gears inside the box turn the output shaft and an electric motor, operatively connected to the gear box, drives the gears. Furthermore, the L-shaped bracket has closed-end elongated slots through which fasteners extend to secure the unitary structure to an inside wall of the deployment apparatus.

Abstract: A planetary gear motor assembly opens and closes a shutter door on a coin dispensing mechanism. The assembly includes a cage having a pair of annular plates with a plurality of cluster gears composed of upper and lower planet gears sandwiched between the pairs of annular plates. The improvement is a plurality of pins on which the cluster gears are placed. Each of the pins is staked at opposite ends to the pair of annular plates so that structural integrity of the assembled cage is retained during rotation and abrupt stopping of the planet gears. A method of manufacturing a planetary gear motor assembly for opening and closing a shutter door on a coin dispensing mechanism includes several steps. Initially, there is assembled a cage having a pair of annular plates with a plurality of cluster gears composed of upper and lower planet gears sandwiched between the pair of annular plates.

Abstract: The timer motor drives a non-circular drive gear fixed on the same shaft as the final gear of the reduction gear train. The final gear is driven by a pinion which is mounted on an axially movable spring loaded jackshaft on which a large gear is mounted with clutch members on the pinion and large gear. When the timer is set the shaft carrying the driven non-circular gear and cam is depressed causing the cam face to depress the jackshaft to disengage the clutch permitting easy rotation of the cam to the desired starting point. The angular motion of the driven non-circular gear and cam is substantially logarithmic with the angular motion increasing as "zero" is approached. When the timer is set the switch is closed to start the motor and the timed device. The lever carrying the cam follower is spring loaded to urge the follower against the cam and to take up the motion in the pin and slot pivot for the lever.
