To all whom, it may concern.-

Be it known that I, CHARLES T. HIGGIN- BOTHAM, of Thomaston, in the county of Litchfield and State of Connecticut, have invented new Improvements in TVatches; andI do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be'a full, clear, and exact description of the same,

My invention relates to an improvement in stem-winding and stem-setting watches, the 5 object being to disconnect the coupler employed for cutting the winding and setting trains into gear from both of the said trains, so that when it is acting upon one train it cannot interfere with the action of the other;

to insure against the cutting of the settingtrain into gear, and thereby disturbing the mechanism.

With these ends in view'my invention consists in a sliding coupler having no direct connection with either the winding or the setting train; in a construction of parts and arrangement of springs whereby the breakage or displacement of the latter cannot operate to out the setting-train into gear; in an auto matic tension relief for the coupler-spring adapted to operate when the movement is re moved from the case, and in certain details of construction and combinations of parts, as will be more particularly hereinafter described, and pointed out in the claims.

As herein shown, my improved mechanism is applied to a movement which may be of any approved construction, only its lower plate A being shown. This movement is mounted in a watch-case B, which may also be of any approved construction, and includes a winding-arbor 0, connected with the movement by a spring D, attached to the plate A thereof and having its extreme lower end squared to enter a corresponding opening formed in the winding'pinion E,held in place by the windingbridge F, and having its opposite end recessed to receive one arm of the operating-lever G, which is pivoted to the in- 0 ner face of the plate by a screw H, the end of the lever entering the recess being directly engaged by the winding-arbor C, the squared end whereof is longitudinally movable in the winding-pinion. The other end of the oper- 5 ating-lever has an inclined open slot I, formed in itto receive an operating-pin J, passing through an elongated slot K, formed in the movement-plate A and projecting inwardly from the outer end of asliding coupler L, the rec outer end of which is guided as it is reciprocated by means of the said pin J and slot K.

The inner end of the said sliding coupler L, which carries no wheel itself, is provided with an elongated opening M, extending in the direetion in which the coupler slides and having its inner wall shouldered to form a bearing for a shouldered winding-cap N, through which the winding-cap screw 0 passes and enters the movement-plate A, the inner end of the said sliding coupler being guided by the said Winding-cap screw and winding-cap cooperating with the elongated shouldered opening. The winding-hub P, formed in the movement-plate A and concentric with the winding-cap screw 0, forms a bearing for the windingwheel Q, which is of ordinary construction, and meshes into the windingpinion E, before mentioned. An intermediate winding-wheel R is mounted in position to gear into the main winding-wheel Q in the lower face of the outer end of a movable carrier in the form of a swinging bar S, the center of which is concentric with the winding-arbor T, the said bar being provided in its outer edge with a notch U to receive an end of a spring V, which exerts a constant tendency to move the free end of the bar inward, and thus cut the intermediate winding-wheel B into gear withthe teeth of the main windin g-wh eel Q. As herein shown, the fulcrumed end of the said swinging bar S is held in place by the ratchet-bridge \V, which is of ordinary construction. The outer end of the sliding coupler L is held down and in place by means of a minute-wheel bridge X, secured to the movement-plate A, the adjacent edges of the coupler and bridge being thereto appropriately shouldered. An operating stud Y, mounted in the lower face of the outer end of the sliding coupler L is provided for engagement with the outer end of a movable carrier in the form of alongitudinally curved or bowed rocking bar Z, free at both ends and located in a long recess a, formed forit in the outer face of the movement-plate A and having its inner end forked to enter a groove encircling a hub 1), formed upon the inner face of a rising wheel c,mounted so as to move freely upon a shouldered stud d, entered into the movement-plate A or formed integral therewith, as maybe convenient. The function of the said rising wheel 0 is to couple the main winding-wheel Q with the minute-wheel e, which is of ordinary construction and meshes into the cannon-pinion f. A spring 9, having its outer end secured to the under face of the sliding coupler L by means of the operatingstud Y, ext-ends inwardly over the rocking bar Z and exerts a constant tendency to depress the inner end thereof, and so depress the rising wheel 0 and cut the same into mesh with the minute-wheel e. A coupler-sprin g h, the function of which is to move the sliding coupler in one direction, has its free end engaged with the extreme outer end thereof and its other end secured to the movementplate A. A tension-relief pin z, mounted in a suitable opening j, formed in the flange 7t,

encircling the movement-plate A, is arranged for the engagement of its inner end with the outer face of the said spring h and for the engagement of its outer end with the inner edge of the case centcr Zwhen the movement is mounted in its case.

Having now described in detail the construction of my improved winding and setting mechanism, I will set forth the mode of its operation.

When the movement is in the case, the winding-arbor is normally pushed inward, as shown by Fig. 5 of the drawings. In this position of the winding-arbor the inclined slot I of the operating-lever will cooperate with the pinJ of the sliding coupler to hold the same in the position in which it is shown by Fig. 1 of the drawings, in which the other parts of my improved mechanism are also shown in their normal or winding positions. By reference to that figure of the drawings it will be observed that the main windingwheel and the intermediate winding-wheel are in-mesh. The position of the rising wheel 0 at this time is clearly shown by Fig. 3 of the drawings, which represents it in its elevated position in which it is cut out of mesh with the minute-wheel e of the dial wo rk of the watch. It will be seen that any movement of the winding-arbor, whether it is turned to wind the watch or ratcheted back, cannot possibly disturb the setting-train of the watch, inasmuch as the sliding coupler is not moved during the operation of winding and is only indirectly connected with the setting-train. \Vhen it is desired to set the watch, the windin g-arbor is pulled outward by its crown, whereby the pressure which it normally exerts upon the operating-lever G is removed and the spring 7L permitted to act in throwing the sliding coupler inward within the limit allowed to itby the length of the elongated slot a, formed in the movement-plate A. As the sliding coupler moves inward, its extreme inner end pushes against the outer end of the swinging bar S and moves the same outward sufficiently to cut the intermediate windingwheel R out of gear with the main windingwheel, whereby the winding-train of the watch is temporarily retired. The same movement of the sliding coupler causes the operating stud Y to clear the extreme outer end of the rocking bar Z, which is turned abruptly upward at that point, and thus permit the spring g to depress the inner end of the said rocking bar, and thus out the rising wheel 0 into gear with the minute-wheel 6, whereby the settingtrain is cut into gear for setting the watch,thc winding-train being meanwhile kept retired by the continued engagement of the extreme inner end of the sliding coupler with the free end of the swinging bar S. After the watch has been set, the winding-arbor is forced inward again by means of its crown, with the effect of causing the operating-lever G to move the sliding coupler outward again against the tension of the spring 72, and thus restore the parts of my improved mechanism to the positions in which they are shown by Figs. 1 and 3 of the drawings.

It has already been seen how the winding and setting mechanism of the watch is sustained in a normal condition of readiness to be operated for winding the watch by means of the pressure imposed upon the operatinglever by means of the winding-arbor. When, however, the movement is removed from the case, this pressure is absent, and in order to provide for sustaining the parts of the watch in the same adjustment the sliding coupler must be relieved of the tension of the spring 72-, employed to move it inward. This relief is provided for in the tension-relief pin 2', which, although normally pressed inward by the case, is free to move outward when the movement is removed from the same, and thus so far relieve the spring 72, from tension that it will not act upon the sliding coupler, which will then be heldin its normal position in which the setting-train is cut out of gear by the action of the spring V, which, as before described, exerts a constant tendency to hold the swinging bar in position for the intermediate winding-wheel to mesh into the main winding-wheel, and at the same time to push the sliding coupler outward. In this tensionrelief pin I therefore provide for keeping the setting-train cut out of gear or retired, even when the movement is out of the case, this being desirable, as otherwise the movement could not be run out of the case without imposing upon it the additional duty of running the main winding-wheel and the winding-pinion. It may be remarked in this connection that if it is desired to cut the setting-train into gear when the movement has been removed from the case a simple pressure of the finger-nail against the outer end of the ten sion-relief pinwill impose the required tension upon the coupler-spring h for throwing the sliding coupler inward and so permitting the depression of the rising wheel and cutting it into gear with the minute-wheel.

The advantage of disconnecting the sliding coupler, which in one position cuts the winding-train into gear and the setting-train out of gear, and in another position cuts the winding-train out of gear and the settingtrain into gear from both of the said trains, is apparent, inasmuch as under this construction it becomes impossible to disturb or injure the train temporarily retired, whichever it may be, whereas under prior constructions, employing a rocking coupler carrying elements of each train at its respective ends, there is an opportunity for interfering with the retired train in case the parts become in the slightest degree deranged or are not carefully managed.

It will be further observed that the breakage of one, two, or all of the springs V, g, and it cannot possibly permit the setting-train to be cut into gear and so affect and impair the integrity of the operation of the watch as a time-keeper. Thus if the spring V should break, the sliding coupler would not be permitted to move inward on that account under the tension of the spring, because the said coupler is positively held in its normal position, in which the setting-train is cut out of gear by the winding-arbor. In case the sprin g g should break, the rocking bar would not on that account he allowed to move, because 1n the normal adjustment of the parts the outer end of the said bar is engaged with theoperating-stud Y. Yet again, if the spring It should break, the adjustment of the parts would be unaffected, except in so far as the pressure against the winding-arbor would be relieved in a measure. Furthermore, in case the spring h should break, the spring V, 1f intact, would exert an effort to keep the sliding coupler in its normal position independent of the adjustment of the winding-arbor. It will thus be seen that in my inventiond have provided for keeping the setting-train normally cut out of gear even when the move ment is out of its case, for disconnecting both the winding and setting trains from the sliding coupler by which they are operated, so that it is impossible to interfere with the train out out while the other is being utilized, and for guarding against the accidental cuttingin of the setting-train, and so destroying the integrity of the operation of the watch as a time-keeper by the accidental breakage of any one, two, or more of the springs employed in the winding and setting mechanism.

Iwish to further call attention to the strong and durable character of the parts employed by my improved mechanism, which in every case are of such construction that they may be made to stand all of the strain imposed upon them in any ordinary usage of the watch.

It is apparent that some changes and alterations in the construction herein shown and described may be made. I would therefore have it understood that I do not limit myself to such construction, but hold myself at liberty to make such variations from it as fairly fall within the spirit and scope of my invention.
