Abstract

109,862. Hall, R. W., and Pearse, D. Oct. 26, 1916. Mechanical telegraphs.-In an apparatus more particularly adapted for mine " men " signalling two dials d, e are employed in the engine room, the dial d for indicating signals transmitted by the banksman and the dial e for signals transmitted ,by the onsetter. The dials are partly obscured, as shown, and pointers, having fingers h, h<1>, j - j<4> in fixed angular relation to one another, are employed, the pointers being ,located behind the dials. For signalling the need of the cage at an intermediate level when the cage is in use at the bottom, a separate signalling device is employed, consisting of a lever at the intermediate level which the onsetter pins in the required position and so operates a pointer l, Fig. 5, at the pit top. The tail of the pointer l moves over an arc m, making electrical contact in each extreme position to ring an alarm bell.
