Slip Gear Drive

A low cost system that permits drive in one direction and slip in the reverse direction is described and illustrated in Figs. 1 and 2.

The platen driven bail closer is gear driven by the platen drive gear 1. Throughout the bail closing cycle, the platen and the bail cam and gear assembly 2 can be driven in either direction except during the time between when the bail arm follower starts down the slope 3 or closing and until the cam is driven far enough so that there is no gear teeth engagement. If reverse indexing is executed during the window, the drive locks up and stalls the platen drive motor. This stall loads the drive system and loses drive registration. To prevent this problem, the bail cam and gear are designed such that the teeth section in this area will flex and permit the platen drive gear to rotate in a reverse direction while the bail cam gear is stationary.
