STEM WINDING AND SETTING WATCH.

EPBGIEIGA TION forming part of Letters Patent No. 350,407, dated October 5, 1886.

Application filed May 8, 1886. Serial No. 201,565. (No model.)

To aZZ whom it may concern:

Be it known that I, ABRAHAM M. YEAKEL, a citizen of the United States, and a resident of Perkasie, in the county of Bucks and State of Pennsylvania, have invented certain new and useful Improvements in Vatches; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a face View of a watch with the face removed, showing my improved stem setting and winding mechanism. Fig. 2 is a similar view showing the device applied to a hunting-case watch. Fig. 3 is a sectional view of the pendant. Fig. 4 is a perspective view of the separate parts of the pendant. Fig. 5 is a view of the winding and setting mechanism seen from the rear side or in a direction opposite to the direction seen in Fig. l, and Fig. 6 is a perspective detail View of the easespring for a hunting-case watch.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of stem winding and setting watches in which the cog-wheels or pinions which engage the cog-wheels upon the post of the mainspring and the cogwheels of the hands are journaled at the ends of a yoke having a common cogwheel engaging the cogwheels at the ends and engaging the setting and winding pinion, and in which this yoke may be tilted, so as to engage either the winding or setting mechanism; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the front plate of the casing of the works, and B is a cogwheel secured upon the post of the mainspring, which is journaled in the said plate to one side.

0 is the cog-wheel which meshes with the pinion upon the post of the minute-hand of the watch, and which is provided with the pinion D, which meshes with the cog-wheelE upon the sleeve of the hour-hand, and this cog-wheel is placed at the opposite side of the stem of the minute-hand to the cog-wheel upon the stem or post of the mainspring.

A yoke, F, has a central circular aperture, G, with which it is pivoted upon a circular disk, H, secured to the front plate of the case, and this disk is considerably thicker than the yoke, having a cogged ring, I, turning upon it, the said ring having outwardly-proj ecting cogs and inwardly-facing beveled cogs J, as plainly seen in Fig. 5. This yoke is formed with inwardly-projecting pins K and L at its ends, and cog-wheels M and N are journaled upon these pins, bearing against the face of the front plate with their inner faces, and meshing with the central cogged ring. The cog-wheel M meshes normally with the winding cog-wheel, while the other cog-wheel, N, may mesh with the cog-wheel of the setting mechanism when the yoke is tilted, so as to disengage the cogwheel from the windingwheel and force it toward the setting cog-wheel.

A spring, 0, is secured at one end near the edge of the front plate of the casing, and the inner free end of this spring bears against a pin, P, projecting inward from the yoke above the cog-wheel which meshes with the setting mechanism, forcing that end upward and forcing the end having the winding-wheel downward, so as to mesh with the wheel upon the post of the spring, and this end is prevented from being tilted too far down by a projecting lug, Q, upon the end of the yoke bearing against a screw or stud, R, upon the front plate. The eogged ring meshes with a beveled pinion, S, secured upon the lower end of a stem, T, or shaft, the upper end of which is formed into either a polygonal tap or a polygonal socket.

A pin, U, slides through a perforation in the upper portion of the side of the casing and in an eye, V, within the casing, and the lower end, XV, of this pin is bent forward and slides in a slot, X, in the front plate of the casing bearing against the upper edge of the end of the yoke having the setting-wheel, while the upper end of the pin projects through said perforation in the side of the casing.

The case-center Y of the watch has the inner or lower end, Z,of the pendant A secured into it, and this pendant is formed with sockets or recesses in its side to receive the ends of the bow-ring B,while its upper end, 0, is re duced and provided with a removable flange or ring, D. A ring, E, fits with its central perforation upon the reduced end of the pendant, and has its upper reduced and screw- 5 threaded end F bearing against the remov- D, which is preferably clinched or riveted to the inner side of the top of the cap projecting down through an axial perforation, L, in the pendant. The lower end of this stem or keypipe fits in or upon the socket or tap projecting up through the side of the casing for the works, so that the works may be wound or set by the turning of the stem or key-pipe and its cap and ring, and the stem or key-pipe is provided with a flange, M, which bears against the upper side of a perforation, N, in the easespring 0, which is secured inside of the casecenter, and has its outer end bearing against the pin projecting out through the side of the inner casing. It will thus be seen that when the cap and ring are revolved the mainspring maybe wound,the winding-wheel being placed with its teeth at such an angle to the teeth of the wheel 13 upon the mainspring-arbor that when the winding-wheel is revolved backward its teeth will slip over the teeth of the other wheel, while its teeth will engage the teeth of the other wheel when wound forward, the teeth of the winding-wheel sliding in between the teeth or cogs of the wheel upon the-mainspring-arbor when revolved forward, while when revolved backward the sides of the teeth will strike the ends of the teeth or cogs of the wheel upon the mainspring-arbor obliquely, so that they will slide over them, the spring at the other end of the yoke allowing the cogs of the wheels to slide over each other, while they will be forced back, meshing with each other by the. spring at the same time.

, \Vhen the watch is to be set, the cap and ring are forced inward against thecoiled spring, and the flange or collar of the stem or key-pipe will bear against the case spring, which again in turn will bear against the end of the pin,which will tilt the yoke with its inner bent end, causing the settingswheel to mesh with the setting mechanism, so that by turning the cap and the stem or key-pipe the cogged rim and the setting-wheel may be revolved. The spring bearing against the stud at the end of the yoke having the setting-wheel will raise that end of the yoke and will raise the pin, so

A colled spung, H, 1s se-c that it will again project when the pressure'is removed from the cap.

In a hunting-case watch the case-spring is preferably constructed as shown in Fig. 6 and in Fig. 2, the free end of the spring being split longitudinally, and the upper portion of the split end is provided with an outwardly-pro jecting latch-lip, P, which engages the lip of the cover,'while the lower portion, Q of the split end is thicker or stiffer than the upper end and carried beyond the end of the same.

The flange or collar upon the stem or keypipe only bears against the edge of the perforation of the lower and longer portion of the spring, and when the said stem or key-pipe is pushed in the lower stiffer end will draw the upper portion will catch with its latch-lip against aportion of the inside case or other portion of the casing, stopping it,while the lower portion will be pushed sufficiently far in to allow the hands to be set.

The coiled spring and the case-spring bearing up against the ring, the upper end of this ring will be forced perfectly tight against the flange or collar at the upper reduced end of the pendant, forming a dust-tight joint, and the lip of the swivelring sliding tightly against the outer side of the pendant will assist in making the pendantperfectly dust and water tight, excluding all dust anddampness, so that if the casing of the watch is perfectly tight no dustorr dampness will be admitted through the pendant, and the watch will be perfectly protected.

The pendant may be used with open-faced as well as with hunting-case watches, and may be used in stem-winding watches as well asin key-winding watches, as thependant is useful as well for simply opening the caseof a watch as for winding it, or for opening the case and for winding it, forming in all cases and forall purposes a tight joint for the stem or key-pipe the ring firmly and thereupon turn the cap' backward, when the cap will be unscrewed and the stem or key pipe may be removed, when the works may be taken out in the usual "manner, and when the works are to be insertedinto the case the stem or key-pipe may be fitted into its proper socket or upon its proper tap, whereupon by revolving the ring and holding the cap firmly the ring may be screwedinto the cap, drawing the cap downward and securing the same. a

The casespring will assist the coiled sprin in holding the ring up against the flange or collar upon the reduced portion of the pendant, and if the coiled spring should by accident be disabled the ease-spring will be able to perform its duties, together with its own, so that the pendant will remain operative.

By this construction of the winding and setting mechanism the hands may be set by simply pushing the cap and ring inward, avoiding the necessity of pushing a setting-lever in or drawing it out, as in usually-constructed stem winding or setting watches, avoiding trouble and preventing the possibility of keepingthesettinglever in position after the hands have been set, in which position the works will be stopped.

Having thus described myinvention, Iclaim and desire to secure by Letters Patent of the United States- 1. In a stem winding and setting watch, the combination of a yoke having a cogged wheel or ring at its pivotal point meshing with a pinion upon a winding-stem, and having a winding-wheel at one end meshing with the central wheel or ring and with a wheel upon the mainspring-arbor, and a cogwheel for setting the hands at the other end meshing with the central wheel or ring, aspring bearing upward upon the setting end of the yoke, a casespring having a perforation near its end for the passage of the setting-stem, a setting'stem or key-pipe having a cap at its upper end and fitting in a socket or upon a tap of the upper end of the inner stem, and having a flange or collar bearing against the outer side of the casespring, and a pin projecting with its outer end through the side of the inside casing and bearing with that end against the end of the casespring, and having its inner end bent outward and bearing against the setting end of the yoke, as and for the purpose shown and set forth.
