Coin operated timing device
First Claim
1. A coin operated electrical apparatus for providing uninterrupted service comprising:
- a timing motor having a shaft adapted to rotate 360* in a substantially given time period, an eccentric cam fixedly attached to said shaft, a cam follower controlled by said eccentric cam and restrained to move in a linear direction, said cam follower has a bifurcated portion defining a pair of spaced-apart arms, said spaced apart arms located in a spaced relationship free and clear of said eccentric cam, each of said spaced-apart arms having an anchoring pin for supporting a pair of heavy duty resilient springs and in which said eccentric cam is forced between said resilient springs whereby rotation of said cam moves said cam follower, a coin chute for accepting a plurality of similarly sized coins, a switch connected in circuit with said timing motor and having an operating arm disposed in said coin chute whereby a coin placed in said chute will contact said arm, close said switch, and operate said timing motor, and a pin fixedly attached to said cam follower and positioned to enter said coin chute and support said plurality of coins in excess of one, said cam follower having a bifurcation defining a lower portion disposed in said coin chute for supporting coins and an upper portion for interfering with said operating arm when a coin is released.

Abstract
A coin operated timing device capable of providing uninterrupted output when a plurality of coins are located in the coin chute. A microswitch having an operating arm located in the coin chute is closed whenever a coin is inserted. A timing motor having a shaft adapted to rotate 360* in a given time period moves a cam follower linearly into and out of the coin chute. The cam follower is restrained for linear movement only and is adapted to support the coins in a first position and allow a single coin to be released while at the same time keeping the microswitch closed for the given period of time. A pin located on the cam follower supports the plurality of coins while the lowermost coin is being deposited without interruption or opening of the microswitch.
