HENRI GERBER, or sr. IMIER, AND HENRI AUDEMARS, OF BRASSUS, ASSIGN- oRs TO ERNEST FRANCILLON & 00., OF ST. IMIER, SWITZERLAND.
STEM WINDING AND SETTING WATCH.
SPECIFICATION forming part of Letters Patent No. 415,632, dated November 19, 1889.
Application filed May 20, 1889. Serial No. 311,389. (No model.) i
To all whom it may concern.-
Be it known that we, HENRI GERBER, of St. Imier, Switzerland, and HENRI AUDEMARS, of Brassus, Switzerland, citizens of Switzerland, have invented a new and Improved Stem- Setting Attachment for WVatches, of which the following is a specification.
This invention relates to improvements in that class of watches that are provided with an oscillating or pivoted yoke carrying a central wheel and side wheels for engagement with the winding-wheel and the hands-settin g train, respectively.
The object of our invention is to facilitate inserting the push-pin and to engage the same with the yoke-operating lever, and to prevent the jumping of-the hands when bringing the setting-gear in engagement with the handssett-ing wheels.
The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and finally pointed out in the claims.
- In the accompanying drawings, Figure 1 is an elevation of the rear side of the main plate of a watch provided wit-h our improvements, the wheels of the movements being shown in dotted circles. Fig. 2 is a view, of that face of the main plate directly behind the dial, the wheels being also represented by dotted circles. Fig. 3 is an enlarged detail horizontal sectional view of the lever for operating the hands-setting train. 7
Similar letters of reference indicate corresponding parts.
The yoke Bis pivoted at B, and carries the centralwheel D, mounted to turn on the pivot of the yoke, and engaging the cog-wheel N, mounted to turn on one end of the yoke and adapted to engage the spring-barrel wheel L. The wheel D also engages the cog-wheel N on the opposite end of the yoke B, said wheel N being mounted to turn freely on the pivot n of the yoke B. A larger cog-wheel N also mounted loosely on the pivot n, is provided with an'aperture 0, into which a pin 0 projects from the under side of the wheel N. Said Wheel N is adapted to be brought into engagement with the pinion S, from which by suitable wheels the hands wheels" can be moved. The tubular pinion P has a squared bore for receiving the lower squared end of the puslrpin T, provided in its cylindrical part with the annular groove T, for receiving the end A of a lever F, mounted to rock on the pivot O, which is screwed into the plate V, said pivot being provided with a shoulderplate 0 and a pin 0 between which pin C and shoulder-plate O the lever F is mounted on said pin 0. The outer end of the screwpivot O is provided with a notch C for receiving a screw-driver. The opposite end of the lever F is provided with the notch F for receiving a pin Q, projecting from a cam V, that can act on one end of the yoke B, said pin passing through a suitable slot V in the plate WV. The cam V is pivoted at V. A spring R, fixed 011 the plate W, presses one end of the yoke B against the cam V. To insert the push-pin, the pivot G is turned by means of a screw-driver in such a manner that it moves outward from the plate TV, as indicated by the arrow X in Fig. 3,whereby the end A of the lever F is moved out of the annular groove T of the push-pin. WVhen the lever F is in this position, the push-pin can be inserted or withdrawn. After the push-pin has been inserted the pivot O is turned in the inverse direction and screwed into the plateNV,whereby the lever F is moved in the inverse direction of the arrow X The end A of said lever passes into the annular groove T, and it is thus a very simple and easy matter to remove the push-pin from the movement or to replace the same. By pulling the push-pin outward the cam is swung downward and brings the wheel N in engagement with the hands-setting train, so that by turning the push-pin the hands can be set. WVhen the push-pin is pushed inward, the cam V is swung-back into the position shown in Fig. 2, the spring R throws the yoke back into the position shown in Fig. 2, the wheel N being engaged with the spring-barrel wheel L, and the watch is then Wound by turning the push-pin. In case the ends of the teeth of the wheel NZwhen the same is brought into engagement with the pinion S, strike the ends of the teeth of the pinion S, said wheel can give slightly, as its aperture 0 is larger than the pin 0 in the wheel N thus permitting the proper meshing of the'teeth N with the teeth of the pinion S Without causing jumping of the hands, as many stem-Winding attachments to watches do.
Having thus described our invention, we claim asnew and desire to secure by Letters Patent- 1. In a watch, the combination, with a pivoted yoke carrying a central wheel engaged with a tubular pinion, of awheel mounted on one end of the yoke and engaged with the central wheel and adapted to engage the spring barrel wheel, a cog wheel mounted loosely on a' pivot on the opposite end of the yoke and engaging the central wheel of the yoke, and provided with a pin projecting from v one of its faces, an additional wheel mounted loosely on the same pivot of the yoke with the wheel having the pin, said additional wheel having-an aperture larger than the pin and into which aperture the pin projects, said additional Wheel being adaptedto engage the hands-setting wheels, whereby the jumping of the hands is avoided when the yoke is adlever having one end in said groove of the push-pin, and a screw-pivot which is screwed in the main plate, and provided with a shoulder or disk on which the lever mounted on said pivot rests, and a pin passed through the pivot at the opposite side of the lever, for the purpose of confining said lever between the shoulder and pin and preventing it from moving longitudinally on the pivot, substan- 4o tially as set forth.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
HENRI GERBER. HENRI AUDEMARS.
