Abstract
Two separate cam means are fixedly and freely rotatably carried on a shaft. Each cam means are simultaneously rotated by a motor at different speeds through a gear train having two separate outputs. Cam lobes are carried on each cam means and engage switch means to open and close same as the cam means are rotated.
Claims7
In a timing mechanism wherein at least two separate cam means are carried by a shaft and wherein a single motor drive means causes rotation of said two separate cam means, an improvement characterized by:
- (a) a first cam means fixedly connected to said shaft and a first switch means engaging same to be opened and closed in response to a rotation of said cam means,
- (b) a second cam means freely rotatably carried about said shaft and a second switch means engaging both said first and second cam means,
- (c) a gear train coupled to said motor drive means, said gear train including first and second output pinions at separate stages thereof to provide two separate outputs at different speeds, and
- (d) first coupling means coupling said first output pinion to said shaft and second coupling means coupling said second output pinion to said second cam means whereby said shaft and said first cam means are rotated at one speed and said second cam means is rotated simultaneously about said shaft at a different speed.
