To all whom it may concern Be it known that we, AUGUSTE HENCHOZ and FRITZ HENCH0Z, both residing at Locle, in Switzerland, have invented a new and useful Improvement in Stop-Watches, of which the following is a speeification. This Invention consists in a stop mechanism of a very cheap construction, in which the hand of the stop mechanism is directly acted upon by a wheel fixed to the axis of the seconds-wheel of the train without any intertmediate transmission. The accompanying drawings show a stop mechanism constructed according to this invention. Figure 1. is a top view of the general arrangement of the stop mechanism; and Fig. 2 shows, an an exaggerated scale, the' section of the pinion of the first wheel (center wheel) of the works, with the axis of the stop-hand traversing the same. The push-piece which acts upon the camratchet G and the corresponding spring are not shown in the drawings, being of the usual construction. Upon the axis A of the secondswheel there is fixed a . f ne toothed wheel, B, which turns continuously with the axis A. The arbor of the pinion C and center or first wheel is hollow, and within it is the axis D, the pivot d of wich passes through a little tube or plug, c, inserted into the tubular arbor C, and this axis D carries the hand E of the stop mechanism. The axis D also carries a fine-toothed pinion, H, und an eccentric or heart-cam, 1, the latter being acted upon by a lever,J,when the hand E is to be returned to its normal position of rest. This lever J is acted upon, as usual, by the cam-ratchet G. The other end of the axis D to the hand is provided with a pivot, cl', turning in the oscillating bridge F. This latter oscillates about a screw, f, and has a projection, F',which bears.' adternately upon a cam or in a notch of the earn-ratchet G. According to the position assi med by the bridge F the pinion H is brought into or thrown out of gehr with the wheel B that is to say, that the stop-band E is put into E,etion or stopped by slightly inoving the oseil-Lating bridge F. A. spring, M, presses the bridge F in the di-
