Abstract

9182. Wilson, W. April 11. [Cognate Application, 13,901/14.] Mechanical telegraphs; bell and gong signals.- Each stroke of the hammer 0 of a bell signal for use in mines turns the ratchet-wheel E through the space of one tooth by means of the pawl I'. A disk D exhibits the number of bell strokes through an opening in a screen A forming one of the supports or bearings for the disk shaft. The disk D has a projection bearing an additional number at the part corresponding to the signal that men are in the cage.. When the winding-engine is started, the apparatus is reset by a spur-wheel P driven by the engine engaging a long - toothed pinion R on the vertical rod Wand so driving the spring-controlled long-toothed rack S to turn the double-armed lever U and thereby the lever I<1>, which raises the pawls I<2>, I<3> and permits the ratchet-wheel E and disk D to run back to zero under the influence of the weight H. In the zero position of the disk, the catch Y mounted thereon depresses one end of the lever X, thereby raising the rod W so that the wheel R is lifted out of gear with the wheel P. At the first motion of the disk, however, the wheel R is again lowered.
