Abstract
A shaft is rotatably journalled between end plates. A first drive gear and a first set of cams are fixedly carried on the shaft. A second cam and a second drive gear are integrally constructed to provide a one-piece construction which is independently rotatable of the shaft. A motor drive has two separate output pinions rotating at different speeds each separately connected to the first and second drive gears. The output pinion connected to the second drive gear is connected through a lost-motion connection.
Claims4
A timing mechanism comprising:
- (a) a shaft rotatably journalled between end plates,
- (b) a first drive gear fixedly carried by said shaft,
- (c) first cam means fixedly carried by said shaft,
- (d) a one piece integrally constructed second cam means and a second drive gear carried by said shaft and independently rotatable thereof,
- (e) motor drive means and a gear train connected thereto, said gear train including at least two output pinions providing two rotational outputs at different speeds, one of said two output pinions connected to said first drive gear, the other output pinion of said two output pinions connected to said second drive gear through a lost motion connection, and
- (f) electrical switch means opening and closing in response to the rotation of said first and second cam means.
