Claims
- 1. 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.
- 2. Transfer arrangement as claimed in claim 1, wherein said cutouts taper toward said disc.
- 3. Transfer arrangement as claimed in claim 1, wherein said first and second counter teeth, and said first and second transfer teeth are made of a thermoplastic material having a predetermined resiliency.
- 4. Transfer arrangement as claimed in claim 1, wherein said cutout in narrow and extends only adjacent and along one of the flanks of the respective tooth and ends short of the tip of the latter so that the resilient flank wall formed by said cutout remains connected at the tip of tooth to the remainder thereof.
- 5. Transfer arrangement as claimed in claim 1, wherein two narrow cutouts respectively extending along and adjacent opposite flanks of the respective tooth are provided, said cutout ending short of the tip of the respective tooth and forming between themselves a core portion and between each cutout and the respective flank resilient flank walls connected at the tip of the tooth to said core portion.
- 6. Transfer arrangement as claimed in claim 1, wherein the cutout in each of the cutout teeth is equidistant from the flanks of said teeth so that resilient flank walls of uniform thickness are formed between the addendum circle and the dedendum circle of each tooth.
- 7. Transfer arrangement as claimed in claim 5, wherein said cutouts taper toward said tip of the tooth.
