The watch case Fig. 7 is a fragmentary transverse sectional is provided with grooves 23 which serve as guide view, showing a modified arrangement for guidor track ways for the actuating member to be '3 ing the weight in the casing. hereinafter described.

The actuating member 24 has an opening 25 therein whereby it fits loosely around the centrally fixed Watch movement I8 and is free to reciprocate lengthwise of the watch case. The member 24 is provided with recesses 26 in which the anti-friction or guide rollers 21 are rotatably secured by screws or pins 26. The manual winding stem 20 of the watch movement extends through a slot 29 in the member 24, said slot permitting the reciprocation of said member within the case without interference from the winding stem. The ends of the member 24 are provided with grooves 30 in each end of which is a cavity 3| to receive the end 32 of a cushion spring 33 whereby said spring is held in said member 24. The cushion springs serve as a means to absorb any vibration or shock incident to the reciprocation of said member 24 within the case.

The member 24 is supported in the watch case body It] by the rollers 21 which travel in the grooves 23 which are provided in the sides of the said body I0. There is sufficient distance between the supporting portions H of the flanges l6 and the walls of the watch case to permit reciprocation of the member 24.

The self-winding mechanism will now be briefly described, reference being had particularly to Figures 1, 3 and 6. The movement I8 includes a main spring (not shown) and a barrel winding arbor 34 for the same. As shown in Fig. 6, the movement includes a main bridge plate 35, in which one end of the arbor 34 is journaled, and an auxiliary bridge plate 36 secured in spaced relation therefrom by screws 31 or the like (Figures 1 and 3). A stud 3B is fixedly secured to the winding arbor 34 and is journaled at its free end in the auxiliary bridge plate 36, and rotatably supports between the bridge plates 35 and 36 a bushing 33 to which is fixedly secured a ratchet 40 and a gear 4|. The winding arbor 34 has a gear 42 secured thereto. The ends of a pin 43 are journaled in the bridge plates 35 and 36.

Secured to said pin 43 is a pinion gear 44 which meshes with the gear 42. Likewise secured to said pinion gear is a gear member 45 which meshes with the gear 4|. The ends of another pin 46 are journaled in the bridge plates. This pin 46 serves as a fulcrum for a U-shaped lever 41 having a forked end 48.

A driving pawl 49, having a hooked end to engage the ratchet 40, is secured to the lever 41 by a pivot pin 5| and is held in constant engagement with said ratchet by a spring 52 secured to the lever 41 by a screw 53. A retaining pawl 54, secured to the bridge plate 36 by a screw or the like as at 51, is normally held in contact with the ratchet 40 by a spring 55. The forked end 48 of the lever 41 is engaged by a pin 56 on the member 24 whereby the winding mechanism is actuated.

Having described the preferred embodiment of the invention, the operation will now be briefly described. When the watch is worn on the wrist of a person, any movement of the Wrist or arm will cause the member 24, which is supported by the rollers 21 travelling in grooves 23 located in the Watch case II), to reciprocate within the case by the action of gravity or by inertia. The pin 56 moving with the member 24 will cause the lever 41 to move in a clockwise direction when said member moves in the direction indicated by the arrow A in Figure 3. This movement of the lever causes the driving pawl 49 to rotate the ratchet 40 in a clockwise direction. This slight rotation of the ratchet will cause rotation of the gear 4| which meshes with a gear member 45. Thus the rotation is imparted through the gear member 45 to the pinion gear 44 which drives the main gear 42 to which the winding arbor 34 is fixedly secured.

When the member 24 moves in the opposite direction to that indicated by the arrow A in Figure 3, the pin 56 causes a counterclockwise movement of the lever 41 about its pivot 46 and the pawl 49 is moved freely over the teeth of the ratchet 40 which is held in position by the retaining pawl 54.

The cushion springs 33 act as shock absorbers to prevent undue strain and vibration when the member 24 reaches the limit of its movement in either direction. It was previously pointed out that the watch may be manually wound and set by the usual stem 20 having the crown 2|! secured thereto.

Figures '7 to 10 show slight modifications of the various parts of the watch. Figure 10 shows a slightly modified form of the member 24. In this case the member 24 has recesses 26 in which are mounted the rollers 21 near the upper face thereof. Figures 7, 8 and 9 show the grooves i3 near the top of the case instead of being centrally located between the bezel and closing plate as in Figures 1 to 6.

It is obvious that minor changes in the details of construction and arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a self-winding timepiece, a case, an apertured member mounted for reciprocationwithin said case, a watch movement fixedly mounted on the case and disposed within the aperture in said member, the dimensions of said watch movement being less than the dimensions of the aperture in said member, a cut-out portion in the side of said member, a manual winding stem extending through said cut-out portion whereby to permit the reciprocation of said member, and means operated upon the reciprocation of said member for automatically winding the watch.
