Abstract

217,204. Seguin, A. June 4, 1923, [Convention date]. Differential speed indicators.-In apparatus of the type described in Specification 184,289 in which a member 4 driven according to the speed to be measured picks up and, at a fixed point releases a striker 5 which actuates a balancewheel 6, the striker 5 is connected to the balancewheel, or to a disc 5a on its spindle, by a yielding member such as a tension spring 101. The object is to control the period of forward motion of the balance-wheel after the striker has been arrested, and to prevent backward movement of the striker until it has been re-engaged by the balance-wheel on its return stroke. In a modification the tension spring 101 is replaced by a curved spring attached at one end to the disc 5<a> and frictionally engaging the striker 5 at the other end.
