PENDANT-SET WATCH.

SPECIFICATION forming part of Letters Patent No. 447,474, dated March 3, 1891.

Application filed September 8,1890. Serial No. 364,273. (No model.)

To all whom it may concern.-

Be it known that LRoswELL L. PEABODY, a citizen of the United States, residing in the city and county of New York, in the State of New York, have invented a certain new and useful Improvement in Pendant finding and Setting lVatches, of which the following is a specification.

I have devised an improved mechanism simple in construction and thoroughly reliable in its action, adapted to apply to all that class of watches having provisions for shifting or changing the winding and setting work from one condition to the other by an endwise movement of the winding-stem. It is equally well adapted to hunting-case or openface watches. I have the ordinary provisions of the hunting-case for liberating the cover by thrusting inward on the crown, and thereby moving the stem longitudinally inward to a sufficient extent to cause it to release a strong catch, the ordinary holding-spring allowing the cover to fly open, and I have the ordinary provisions of the pendant-setting watch for adjusting the parts for setting by simply pulling outward on the crown and thereby temporarily disconnecting the winding mechanism and connecting the setting mechanism. I provide a partially-revolving piece, which I term a cam and an operating-lever therefor, both interposed between the yoke and stem. These parts are arranged to allowalarge amount of idle motion. hen the stem is thrust inward and allowed to be returned to effect the frequently-recurring opening and closing motions of the huntingcase, the lever and connected cams swing idly through the small are required. \Vhen the stem is temporarily drawn outward, these parts are set at liberty, and are operated by a spring to reliably shift and hold the yoke in position for setting the hands. I have devised an improvement in the yoke, whereby the arm which operates it is bent downward and affords a wide bearing, against which a thin intermediate cam sunk to a lower plane may work without risk of slipping past until the yoke is moved in position for setting the hands. I have devised a lever having a bearing end correspondingly bent down, which affords a broad bearing against the operating-collar on the winding-stem.

The accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention.

' Figures 1, 2, and 3 are face views with certain portions removed. Fig. 1 shows the mechanism in condition forwinding. This is the condition in which the watch is ordinarily maintained. Fig. 2 is partly in sec tion. It shows the crown drawn out to put the mechanism in condition for setting. Fig. 3 shows the crown pressed inward to lib-v erate the cover. Fig. 4: is an edge view of the watch, partly in section. It shows the mechanism in the same condition as in Fig.

l. The remaining figures are on a larger scale. Fig. 5 is a cross-section. It shows an edge view of the arm of the yoke with its end bent down, and a section of the adjacent part of what I term the cam. Fig. 6 is a corresponding cross-section of another portion of the watch. It shows an end view of the internal stem, sometimes called the snap-stem, viewed from the interior of the watch, andan edge view of the lever, the end of which is bent down and pressed against a collar on the stem. Fig. 7 is a view of the stem and loose collar thereon and of the winding-pinion carried on its extreme inner end.

Similar letters of reference indicate corresponding parts in all the figures where they appear. 7

A is the stationary casing of the watch, certain parts being designated, when necessary, by additional numbers, as A A The pendant A, the bow N, the cover 13, and the catch C, which holds the cover, may be all of the ordinaryand long-approved construction.

D is the snap-stem, an internal stem fitting in the pendant, with liberty to be revolved by acting on the ordinary crown outside, and also to be pressed or thrust inward against the force of a strong spring 0 and to be drawn forcibly outward to the proper limited extent to adjust the watch for setting. The stem is provided, as usual, with a collar D, which receives springs E, set in the pendant, which serve to hold the stem alternatively in the two conditions with regard to setting and winding-that is to say, when the stem is forcibly drawn outward the collarD' is moved outward past the point of bearing of the IOC springs E, and is retained in the outward po sition so long as is required to set the watch. 'WVhen this has been carefully completed, the stem must be thrust inward again by a .sufficient pressure on the crown to carry the collar D inward past the springs E, and thence forward the springs serve to hold the stem inward.

G is a yoke which carries the gearing which in one position engages with the geanwheel H, only a part of which is shown, and effects the winding, and in another position engages with the cannon-pinion I, which is on the central arbor and effects the setting. an arm thereon which extends radially outward and is bent downward at a right angle, extending into a sufficient recess to be presently described. It is acted on by a spring J, tending to hold the yoke always in position for winding, except when it is acted on by a sufficient force to throw it into the opposite position.

K is a partially-rotating plate, which I term a cam, sunk in a recess in the pillar-plate of suitable area and form to allow it a wide range of motion. It is pivoted on a screw 70 and performs important functions. Its edge K is adapted to act as a lifting-plane against the arm G of the yoke G, and moves the latter into position for setting the hands. The entire cam is subject to the force of a spring L, which presses against a pin K and tends constantly to turn the cam in one direction.

M isa lever turning on a fixed pivot m on the front of the pillar-plate. Its long arm receives from a pin K in the cam K the force of the spring L. The other, the short arm of the lever M, is bent downward at right angles, extending through a sufficient hole provided in the pillar-plate, as shown by M in Fig. 6. This bent end affords a large hearing which is pressed against a collar D on the stem D. This collar controls the position of the cam K. While it stands in the position shown in Fig. 1 it holds the lever M in such position that its contact with the pin K holds the cam K idle. When, on the contrary, the stem D is drawn forcibly outward, so that the springs E snap over the collar D, this change of position of the collar D sets the lever M at liberty, and it relaxes its resistance to the pressure of the pin K Then the spring L, acting on the pin K turns the cam K, and thereby turns the yoke G into the position shown in Fig. 2, and rigidly holds it there by reason of the cam K having turned so far that its angle presses the bent arm G. Now the latter rests on the small section 70' of the cam K,

. which may be concentric to the center of the yoke G and the spring J turns the yoke into the position for winding, which is the original position, that shown in Fig. 1.

O is the ordinary stout catch or spring-head which engages and releases the cover B of the watch-case. This is important when the case is a hunting-case. The catch is traversed by the stem D, and is subject to the action of a shoulder D thereon. The stem D is free to be pushed inward to the extent'necessary to actuate this catch. The squared portion on the inner end of the stem D is of snfficient length to allow the stem to move endwise in the correspondingly-squared hole in the winding-pinion. There is provision by a sufficient space under the crown and at the engagement with the springs 'E for such mo-,

tion of the stem.

The form of the lever M and cam K and the arrangement of their respective centers allow provision for the-motion given to thelever M and to the connected cam K, these parts M and K swinging or partially revolving idly in their respective places at each opening and closing of the watch. The cam K difiers from ordinary devices for this purpose in having the lifting-plane K wholly on the cam, instead of mostly or wholly on the yoke. Sinking the cam below the plane of the yoke avoids the action of thin edges on each other in the same plane or parallel, thereby avoiding risk of slipping off and getting much better results.

All the parts are made to gages and are interchangeable. This allows the Works to be transferred from one case to another.

With the winding work in its normal position, Fig. 1, the crown has been pushed home on the pendant, carrying with it the windingstem D, the collar D which forces the bent end of the lever M toward the center of the watch, causing the opposite end of this lever toact on the pin or stud K and swing the cam K away from the arm G of the yoke G, and has allowed the latter to turn by the force of the spring J and assume the position for winding. Drawing the crown forcibly outward allows the collar D .to recede and relieves the pressure of the lever M on the stud K and the spring L, acting on the stud K swings the cam K so that its straight edge K comes in contact with the arm G of the yoke,

turning the latter into position to engage the setting-wheels with the cannon-pinion or with a connected wheel ready for setting the hands. Releasing the crown and forcing it inward again operates the lever M to turn the cam K again into the idle position, and the yoke G is again forced by the gentle spring J into the position for winding. In closing the cover the catch 0 is operated and the cam K is turned idly. When-at any future period the crown is pressed inward to a sufficient extent, this catch 0 will be operated, and if the case is a hunting-case this is the proper movement to effect the opening of the case. It has no effect on the yoke G and its connections.

My invention serves well with huntingcases, a desideratum heretofore unattained in mechanisms of this character for watches that are interchangeable from one case to another.

Modifications may be made without departing from the principle or sacrificing the ad vantages of the invention. Instead of bending the metal of the arm G, the metal may be finished straight and a pin inserted reaching downward to the same extent.

setting mechanism and having the bent arm G and actuating-spring J, in combination with the cam K and spring L, acting on the stud 1 and with the lever M M and the stem D, having the collar D and arranged to be moved endwise as well as rotated, as set forth.

3. In a stem winding and setting watch, a pull-stein I) D, a spring-head C, operated by thrusting the stem and adapting the mechanism to serve in a hunting-case, and the lever M, cam K, intermediate between the lever and the yoke, said cam carrying the pins K and K and the actuating-spring L, in combination with each other and with the yoke G and its operating-spring J and the gearing for winding and setting, all arranged to serve substantially as herein specified.

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.
