Abstract: A coin chute trigger assembly having separate coin paths for nickels, dimes, and quarters. Intentionally, the dime coin path is made at least twice as wide as the thickness of a dime in order to prevent hangups and jams. A trigger included in each coin path is operated in response to deposit of the appropriate coin through the coin chute or path and causes operation of an included pair of switching contacts.

Abstract: A coin chute trigger assembly having separate coin paths for nickels, dimes, and quarters. A microswitch is positioned adjacent to each coin path. A trigger included in each coin path is operated in response to deposit of the appropriate coin through the coin chute to cause operation of the included or adjacent microswitch.

Abstract: A toggle switch construction operating in conjunction with a conventional coin slide acceptor to produce a single signal each time the coin slide is reciprocated. The switch is mounted upon a support member, which, in turn, is mounted for limited pivotal movement during actuation by a member on the coin slide such that the member, after actuating the switch passes over the toggle. On the return movement of the coin slide to its initial position, the toggle is re-engaged and returned to its initial position, following which the member again passes over the toggle. The toggle can therefore be cycled only once for each reciprocation of the coin slide.

Abstract: A belt filter press comprising two co-operating, endless belts, particularly for manure, which according to the invention takes steps to enable liquid and solid substance to be better separated from each other. The pressure between the endless belts is increased, the longitudinal edges are sufficiently sealed and substance that is still too moist is subjected repeatedly to compression since it remains stuck to the upper endless belt and is carried to the intake of the belts.

Abstract: A money operated control is used to control and operate a selected one of a plurality of electrical units such as washing, drying or gas-dispensing machines. Each such unit includes a unit controller device operable to control the functioning of the unit upon delivery of a start signal to the unit controller device. A central control panel includes a latching relay which when pulsed to its set state energizes a transformer. The transformer in turn energizes a switching unit in the central control panel which selects one of the electrical units to be energized. The actuation of the selected electrical unit resets the latching relay to its original condition and additional relay circuitry is provided so that the connection to the machine in use does not interfere with subsequent operation of the control panel to select other machines.

Abstract: This invention is a coin operated switch which may be incorporated into coin operated machines such as video games to reduce cheating of the credit granting feature of the machines. This invention incorporates two electromechanical switches and circuitry which further use the existing machine circuitry to time the travel of a coin between the switches and to grant a credit on the machine only if each switch is tripped and released in the proper order and within the predetermined elapsed time.

Abstract: This disclosure is directed to a switching device for a coin controlled machine in which the device is actuated in response to completion of a predetermined number of cycle of an operator member. The device includes a shaft disposed for rotating a predetermined angular increment each time the operator member cycles. The device includes a first cam and a second cam adjustably positioned on the shaft relative to each other to permit selecting a predetermined distance along the camming surface of the first cam between the initial inoperative position of said first cam and its actuation position. The angle subtended by the selected predetermined distance along the camming surface of the first cam is a multiple of the predetermined increment that the shaft rotates each time the operator member cycles.

Abstract: Upon insertion of a coin into a receiver of a timing mechanism, an actuator rotates a ratchet which in turn rotates a cam. The cam and a disc each have a tab extending therefrom. When the ratchet and cam are rotated, the tabs separate from each other providing a desired timing cycle and the cam is set to close electrical switches. When the timer is operative, the disc rotates causing its tab to engage the tab of the cam to rotate the cam and open the electrical switches.
