ABSTRACT:
A presettable counter operated control mechanism employing a spring lock latching arrangement for releasably locking a rotatable control member in different angularly loaded positions. A coil spring connected to the control member encircles a first drum and is selectively frictionally anchored to the drum by a latching arrangement which is releasable by the counter reaching a referenced count to releasably lock the control member at a particular angular position. Two latches provide for releasably locking the control member at two different angular positions thereof, and are tripped at two respective referenced counts, with both latches being tripped at the later reference count. Final release of the control member is operative to terminate counting operation.
An interlock between the control member and the wheel presetting mechanism prevents interference with the setting of the counter wheels while the control member is locked and the counter is counting. The interlock allows the counter wheels to be preset only after the control member has been finally released and the counting terminated.
