Abstract

229,713. Harris, H. K. Aug. 23, 1923. Intermittent - toothed gearing. - A Geneva stop mechanism comprises a constantly - rotating wheel 200 having a smooth periphery 66, a small section 69 of this periphery being, however, toothed. The pinion 63, part only of whose surface carries teeth, is normally idle and in the position shown, but when the projection 68 is carried by the wheel 200 into engagement with the horn 64 fixed to the wheel 63, the teeth of the latter engage the teeth 69 and the shaft 61 performs one complete revolution.
