Abstract

756,835. Vibration dampers. NATIONAL CASH REGISTER CO. Dec. 22, 1954 [Jan. 4, 1954], No. 37050/54. Class 108 (3). [Also in Group XIX] In order to assist the homing of a machine part, e.g. a reciprocating bar 5, against a stop and inhibit rebound from the stop, teeth 18 on the member are in loose mesh with a rotatable gear 16. The bar 5 is adapted to be reciprocated by the follower 8 of a cam 11 and is moved up to a stop 15 when the follower is released to its spring 10 by a drop 13 in the cam. The inertia of the gear causes it to overrun the bar when arrested and the forward impact of its teeth against the teeth 18 assists a full stroke of the bar besides resisting rebound. The gear also resists excessive acceleration of the bar. The teeth of the gear are bevelled, and the gear is mounted on an adjustable eccentric 21 to allow the tooth engagement to be varied. The gear may be constructed with cavities 22 partly filled with lead shot 23 or other heavy material. The invention is applicable to the differential actuators and line-finding mechanisms of calculating and similar machines. It is also applicable to the rotary driving mechanisms of such machines, for equalizing the load over the machine cycle and ensuring completion of the cycle.
