Abstract

11,300. Pailweber, J. May 17. Calculating-apparatus.-An adding-machine is arranged so as to be nearly noiseless. A key, when depressed, slides along an inclined surface c of the bar a, thereby moving it on a roller b a distance corresponding to the number on the key. Springs f, d move back the key and the bar respectively. The motion of the bar is communicated by a rod e, lever, and pawl to the wheel g of the counting-mechanism. The stop-pawl o, shown in detail in Fig. 5, is loosely held by pins i on the piece n, and falls by its own weight between the teeth. Its motion is restrained and silenced by the spring piece q.
