WATCH-WINDING DEVICE.

$PECIFICATIN forming part of Letters Patent No. 320,609, dated June 23, 1885.

Application filed January 26, 1885. (No model.)

To aZZ whom it may concern:

Beit known that I, ARTHUR G. WIsnMAN, of lVebster Groves, St. Louis county, Missouri, have made a new and useful Improvement in Watches, of which the following is a full, clear, and exact description.

The improvement relates to the winding By means of it watches which have been constructed to be wound with akey can be adapted to be wound by an attachment permanently connected with the watch.

The accompanying drawings, making part of this specification, illustrate a watch having the improvement.

Figure 1 is a face view of a watch having the improvement, the case being opened. Fig. 2 is a view of the opposite side of the watch, the outer and the inner case being opened. Fig. 3 is a view, upon an enlarged scale, of that part of the Watch with which the improvement is immediately connected, the View being similar to that of Fig. 2, and showing the pawl as at the commencement of its forward stroke. Fig. 4 is a view similar to that of Fig. 3, but showing the parts as at the termination of the forward stroke of the pawl. Fig. 5 is a view in perspective of that portion of the pawl which engages with the ratchet. Fig. 6 is a view in perspective of the main part of the pawl, and Fig. 7 is a view in perspective of the spring used to effect the engagement of the pawl with the ratchet.

The same letters of reference denote the same parts.

The watch A, Figs. 1, 2, is of a familiar form, saving as modified by the improvement in question.

B represents ablock held and adapted to be moved to and fro in a slot, a, in the rim a of the watch, as indicated by its two positions shown, respectively, in Fig. 3 and in Fig. 4. The block at its outer side is extended to form, or is provided with or has attached thereto, a projection or boss, 0, which extends outward from the rim sufficiently to form a shoulder against which the finger can be pressed and the boss thereby be moved along the rim of the watch. The boss is extended at c and 0 beyond the ends of the block B, to form a cover for the slot a as the block and boss are moved forward and backward in and upon the watchrim. At its inner side the block is connected with a ring, D, which is held loosely in the watch just within the rim. The block, boss, and ring are conveniently fastened together, so as to permit of them being moved as one piece by means of the bolt (1.

E represents a pawl, which at c is jointed to the ring, and whose free end is adapted to be moved into engagement with the ratchet F. This ratchet is fastened to the ordinary winding-shaft, Gr, and therefore if the ratchet is rotated the winding of the watch is effected.

The rotation of the ratchet is accomplished by means of the above-described mechanism in connection with the spring H, which at his fastened to the frame-work of the watch, and whose end It is adapted to press the pawl into engagement with the ratchet, saving as hereinafter explained. As the boss, block, ring, and pawl are moved backward, the teeth of the pawl ride upon the ratchet-teeth; but when moved in the opposite direction the pawlteeth engage with the ratchet-teeth and the ratchet is rotated. It is essential, however, that the winding-shaft and ratchet, after the Winding is accomplished, be left free to unwind as the watch is used. To this end the pawl at the end of its backward stroke is disengaged from the ratchet, and preferably in the following manner: The end 0 of the pawl is beveled, and as the pawl is moved backward the end 0 encounters a stop, I, Figs. 3, 4, and the free end of the pawl is thereby moved toward the rim to and disengages from the ratchet. When the pawl is drawn forward, the end c',as soon as it passes the stop I, is moved from the rim, and the engagement of the pawl with the ratchet is reestablished.

As the pawl-teeth are liable as the pawl is moved against the ratchet to encounter the points of the ratchet-teeth, and in consequeme not to become engaged with the ratchet-teeth, the pawl is preferably made in two parts, E and E. The main part E is the one which is attached to the ring D and encounters the stop I. The other part, E", is the one which has the pawl-teeth It is slotted at c c, and it is connected with the part F/ by means of the screws 6 c, which pass through the slots 0 e and are screwed into the part B. The two parts E and E thus connected are moved as one part toward and from the ratchet by IOC the spring H; but in the direction of the length of the pawl the part E at every stroke of the pawl has a movement upon the part E equal to the length of the slots 0 c-thatis, after the pawl-teeth have caught on the ratehet-teeth the part Fl slips upon the part E until the ends of the slots are reached, whereupon the part F is drawn forward and the ratchet is rotated. New, by reason of the part 15 being adapted to thus slip upon the part E, a better opportunity is provided for the pawl-teeth to become engaged, and the pawl at every forward stroke operates to re tate the ratchet.

The spring H bears against the back of the part E. It is preferably provided with the extension 72 which projects over the part E, as shown in Figs. 3, 4-, and serves as a guard to hold the pawl down in place, and so as to keep the pawl-teeth in the plane of the ratchet. The spring is also widened at if, so as to project over the ring D and hold it down in its place.

The position of the pawl when deflected toward the rim by means of the stop I is shown in Fig. 2. The stop and the parts E 1& are allso relatively shaped and connected as to cause the part E by reason of its end a" coming against the stop,to he slipped forward (that is, in the direction of the block B) upon the part E.

The pawl E, after the winding of the watch has been accomplished, should not only be disengaged, but should remain disengaged from theratchet until the time for anotherwinding. To this end the ease L ol'the watch is provided wit-l1 a pin, J, which by closing the case engages in a hole, K, in the block when the latter is in the position shown in Fig. 2. The block and pawl therefore remain in that position until the case is opened again, which movement must precede the winding of the watch.

I claim 1. The combination, in a watch, of the slotted rim a, the block B, the boss 0, the ring I), the pawl E, the spring H, the stop I, and the ratchet F, as and for the purpose described.

2. The combination, in a watch, 01' the ring D, the pawl E, the ratchet F, the spring H, and the stop I, substantially as described.

3. The combination, in a watch, of the ring D, the pawl E, the ratchet F, and the stop I, as and for the purpose specified.

4;. The combination, in a watch, of the ri ng l), the pawl E, made in the two parts E and E, constructed as described, the ratchet F, and the spring II, substantially as set forth.

5. The combination of thespring H, widened at Zr, and the ring D, as and for the purpose set forth.

6. The combination of the ring D, the part E, the part E", having the end and the stop I, as described.

7. The combination of the case L, the pin J, and the block B, having the hole K, as and for the purpose described.

XVit-ness my hand this 23d January, 188.3.

ARTHUR G. XVISEMAN.
