LEO E. DONNELLY AND JOHN H. LOONEY, OF ITALY, TEXAS.

. STEM WINDING AND SETTING WATCH.

' SPECIFICATION forming part of Letters Patent No. 613,411, dated November 1, 1898.

Application filed June 8, 1897. Serial No. 639,904. (No model.)

To all whom it may concern.-

Be it known that we, LE E. DONNELLY and JOHN H. LOONEY, citizens of the United States, residing at Italy, in the county of Ellis and State of Texas, have invented a new and useful Winding and Setting Mechanism for Watches, of which the following is a specification.

' This invention relates to mechanism for winding and setting watches by means of the pendant, and is applicable to open or hunting case watches, and has for its objects to reduce the primary cost of such mechanism both as to material and time required for fitting it to the movement and case, to secure the movable part of the pendant against displacement and loss, to simplify the construction and reduce the operating parts to a minimum number, and to supply a mechanism for the purpose aforesaid which will be effective, durable, easy of manipulation, and not liable to derangement.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a view in elevation of a watchmovement, showing the application of the invention, the mechanism being in position for winding the spring. Fig. 2 is a View similar to Fig. 1, showing the mechanism as it will appear when moved to a position for setting the hands. Fig. 3 is a transverse section through the pendant and parts intimately associated with the winding and setting mechanism. Fig. 4 is a transverse section of the pendant on the line X X of Fig. 1. a top plan view of the fixed portion of the pendant. Fig. 6 is a detail perspective view of the outer or movable part of the pendant.

Corresponding and like parts are referred to in the following description and indicated in the several views of the accompanying drawings by the same reference characters.

The watch-movement comprises a train of Fig. 5 isgearing of any type, of which the spur-wheel applied to the arbor of the winding-spring is represented by the numeral 1 and the idler intermeshing with the pinion on the post bearing the hands is indicated by the reference character 2, said movement being inclosed in a case provided with a pendant composed of a boss 3 and a movable part 4, having the bow 5 applied thereto.

The yoke 6 is mounted upon a flanged collar 7, placed upon a screw 8, let into a plate 9 of the movement, and is provided at one end with a spur-gear 10 to mesh with the idler 2, as shown in Fig. 2, when the mechanism is in gear for setting the hands, and at its opposite end with a spur-gear 11, normally intermeshing with the spur-gear 1 to admit of the spring being wound when required to maintain the movement in running order. A spring 12 is secured at one end to the plate 9, and its opposite end enters a notch formed in an edge of the yoke and exerts a pressure on the latter sufficient to maintain the spur-gears 1 and 11 in meshing relation.

The yoke 6 is formed with an extension 18, projecting toward the pendant and provided with a lateral extension 14, adapted to be en= gaged by a lug 0r projecting part 15 at the inner end of the hollow shank 16, forming a part of the movable portion of the pendant, whereby upon turning the latter the yoke is vibrated upon its pivotal support to bring the spur-gears 2 and 10 into engagement to enable the hands of the watch to be moved. The master-gear 17 is concentric with the pivotal support of the yoke and meshes with the spurgears 10 and 11 and is formed on its inner face with a crown-gear meshing with the bevel-pinion 18, receiving the inner angular end of the stem 19,which is rotatably mounted in the pendant and has connection at its outer end with the crown 20, by means of which the stem is rotated for winding or setting the watch, as desired.

The boss 3 is rigidly applied to the casing and is formed with a longitudinal bore which is internally threaded. The outer edge of the boss is reduced, and its outer end is formed with an annular groove 21 to receive the inner ends of screws 22, passing longitudinally through openings formed in the movable part 4 of the pendant. The end portions of the bow 5 enter lateral openings 23, formed in the sides of the part at at diametrically opposite points, and annular grooves 24: are provided in the end portions of the bowadjacent to their extremities and receive the inner ends of the screws, pins, or fastenings 22, whereby the bow is retained in position against accidental displacement. The openings provided in the movable part i of the pendant intersect with the lateral openings 23, thereby admitting of a portion of the screws or pins 22 projecting into the lateral openings 23, whereby an interlocking of the parts 22 and 5 is had. The inner end of the part 4: is recessed to receive the reduced end of the boss 3, whereby a close joint is had between the parts 3 and 4, and the space between their meeting faces is normally closed. The hollow shank 16 is externally threaded and screws into the longitudinal bore of the boss, and the lug or projecting part 15, provided at its inner end, is disposed so as to engage with the lateral extension 14 upon turning the part 4, whereby the mechanism is thrown into gear with the idler 2 to admit of the hands being set when required.

The movable part 4. of the pendant has a limited movement to admit of the mechanism being thrown into gear for setting the hands, and in order to prevent the teeth of the gears 2 and 10 from binding the turning of the part 4 is limited the instant the gears 2 and 10 intermesh. This result is attained by properly adjusting the screws 22, so that their inner ends will engage with the bottom of the groove 21 the moment the toothed portions of the parts 2 and 10 intermesh, thereby preventing the further turning of the part 4. The sides of the screws 22 engage frictionally with the walls of the groove 21 to prevent a too-free turning of the part at except at the will of the user, whereby the yoke will not be accidentally turned upon its pivotal support to throw the mechanism into engagement with the idler 2 and move the hands after the watch has been properly timed.

Having thus described the invention, what is claimed as new is- 1. In a pendant-set watch, the combination with the pendant comprising a fixed and a movable part, the latter having screw-thread connection with the fixed part and provided with a lug at its inner end disposed eccentrically to its axis, ayoke bearing a train of gearing to be brought into engagement with either the winding or the setting mechanism, and having an arm provided with a lateral extension to be engaged by the lug of the movable part of the pendant, and means having adjustable connection with and applied to the movable part of the pendant to come in contact with the fixed part of the said pendant and limit the turning and the longitudinal movement of the said fixed part of the pendant and prevent the crowding of the toothed portions of the cooperating gears when turning the yoke to throw the train of gearing carried thereby into meshing relation with the winding or setting mechanism, substan= tially as set forth.

2. In a pendant-set watch, the combination with a yoke bearing a train of gearing to intermesh with the winding and setting mechanisms, of a movable part forming a portion of the pendant, and having screw-threaded connection with the other part, and having a lug or projection to be brought into engagement with a portion of the yoke for turning it upon its pivotal support, and a screw mounted in a longitudinal opening of the movable part of the pendant and adapted to engage with the inner or fixed part of the pendant to limit the turning of the movable part, sub stantially as set forth for the purpose de= scribed.

3. In combination, a yoke bearing a train of gearing to be thrown into engagement with the winding and setting mechanisms, a pendant comprising a fixed boss and a movable part, the latter having a hollow shank making screw-thread connection with a bore of the boss, and having a lug or projection at its inner end to engage with the yoke for moving the latter, a stem mounted in the pendant for operating the winding and setting mechanisms, a bow having its end portions annularly grooved and entering openings in the sides of the pendant, and screws longitudinally mounted in the movable part of the pendant and interlocking with the end portions of the bow, and adapted to engage at their inner ends with the boss to limit the relative turning of the movable part of the pendant, and constructed to prevent accidental turning thereof, substantially in the manner set forth for the purpose specified.

In testimony that we claim the foregoin as our own we have hereto affixed our signatures in the presence of two witnesses.
