Abstract
Two successive ordinal toothed counter wheels are connected by toothed transfer means to make a tens-transfer once during each revolution of the counter wheel of the lower order. The teeth of the counter wheels and of the transfer means are cut out and hollowed so that the teeth are resilient and dampen impacts thereon during the transfer operation.
Claims7
Damped transfer arrangement for a counter comprising at least first and second ordinal counter wheels having first and second counter teeth, respectively;
- a transfer wheel secured to said first counter wheel and including a peripheral rim having a first transfer tooth;
- and a transfer gear of deformable thermoplastic material and having second transfer teeth meshing with said second counter teeth and having a locked position in which one second transfer tooth slides on said peripheral rim for locking said transfer wheel and second counter wheel, another second transfer tooth being engaged with an impact by said first transfer tooth once during each revolution of said first counter wheel so that said transfer gear is angularly displaced for turning said second counter wheel, said first and second counter wheels and said transfer gear each include a disc, and said first and second counter teeth and said transfer teeth axially project from the respective disc and are formed with cutouts extending from the radially inner end of each tooth into the latter short of the radially outer end thereof so as to provide in each cutout tooth axially projecting, resilient, in tangential direction yieldably flank walls connected to each other only at the addendum circle and having free ends at the dedendum circle to dampen the impact.
