Abstract

17,733. Viette, T. C. L. Aug. 26, 1909, [Convention date]. Pneumatic signals.-In systems of the kind in which the room from which a call proceeds is indicated by a lighted lamp placed near the room itself, a second visible signal is provided, which is further utilized to close the contacts of the lamp circuit. The indicator a is normally held up as shown in Fig. 5. The operating- means, which may be pneumatic, instead of electric as shown, move the rod c, and the indicator drops to the position shown in Fig. 3, where the head j of the indicator touches the two contact springs h to complete the circuit of the lamp r.
