STEM WINDING AND SETTING WATCH.

EBPECIFIGATIONforming part of Letters Patent No. 325,506, dated September 1, 1885.

Application filed June 18, 1885. (No model.)

To all whom it mag concern:

Be it known that 1, CHARLES P. CORLISS, of Elgin, in the county of Kane and in the State of Illinois, have invented certain new and useful Improvements in Stem Winding and Setting "Watches; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure l is a plan view, from the dial side, of a watch-movement containing my improvements, the shifting mechanism being shown in position for connecting the stem-arbor with the mainspring-arbor. Fig. 2 is a like view of the same with said parts in position to cause engagement of the stem-arbor with thedialwheels. Fig. 3 is a plan view of the opposite Figs. 4 and 5 are perspective views of the same, and show, respectively, the positions of parts represented in Figs. 1 and 2. Fig. 6is a perspective View from below of the parts of the stem-driven train separated from each other and from the movement plates and case; and Figs. 7 and 8 are sections upon lines x w of Figs. 1 and 2.

Letters of like name and kind refer to like parts in each of the figures.

My invention relates to watches in which the winding and hands-setting train is moved into engagement with the winding-wheel or dial-wheels by a movement of the stenrarbor; and it consists, principally, as an improvement in stem -winding and hands setting watches, in a winding and handssetting train which is adapted to be placed in engagement with the winding-wheel by the movement of a stenrarbor, and is normally in engagement with the dial-wheels only when the movement is in a case, substantially as and for the purpose hereinafter specified.

, It consists, further, as an improvement in stem winding and setting watches, in a winding and hands-setting train which is adapted to be placed in engagement with the windingwheel by the movement of a stemarbor, and

is normally held in engagement with the dialwheels by a spring that is only operative for such purpose when the movement is in the case,substantiall y as and for the purpose here inafter set forth.

It consists, further, as an improvement in stem winding and setting watches, in a winding and hands-setting train which is adapted to be placed in engagement with the windingwheel by the movement of a stem-arbor, and is held normally in engagement with the dialwheels by means which are operative for such purpose only when the movement is in a case, substantially as and for the purpose herein after shown.

It consists, further, as an improvement in stem winding and setting watches, in the combination, with a winding and hands-setting train, of a spring which operates to hold said train normally in engagement with the dialwheels when the movement is in a case,and is inoperative for such purpose when said movement is removed from its case, substantially as and for the purpose hereinafter shown and described.

It consists, further, as an improvement in stem winding and setting watches, in a winding and handssetting train which, when the movement is cased, is normally held in em gagement with the dialwheels, and when said movement is removed from its case is automatically relieved from constraint and free to engage with the winding -wheel, substantially as and for the purpose hereinafter specified.

It consists, further, in the means employed for moving the shiftable stem-driven wheel into and out of engagement with the springwinding and hands-settingmechanism, substantially as and for the purpose hereinafter shown.

It consists, finally, in the means employed for operating the shifting mechanism, substantially as and for the purpose hereinafter set forth.

In the annexed drawings, A represents the pillar-plate, and B the back plate of a watchmovement, in which movement is provided the usual time-train.

J ournaled upon the rearward projecting end of the mainspring-arbor G is a toothed wheel, D, that is engaged by a similar smaller spun wheel, E,'which is journaled at one side of the same, and upon its lower face is provided with bevel or miter teeth 6, that engage with IO.)

the teeth of a bevel-pinion, F, which is enmovement against the resistance of the spring gaged axially by the inner end of a stemarbor, G, the arrangement being such as to enable said wheel D to be revolved in either direction by the rotation of said stem-arbor.

As before stated, the wheel D is shiftable lengthwise of the spring-arbor O, and when at its lowest point thereon engages with said arbor by means of a clutch-face, (1, upon the lower side of said wheel, and a correspondingly-opposite clutch face that is provided upon a ratchet-wheel, c, which is attached to and rotates with said arbor, the arrangement being such that when said wheel and arbor are thus engaged the latter may be revolved to wind the mainspring by the rotation of the stem-arbor G. "When the wheel 1) is moved outward to the limit of its motion in such direction, it is relieved from engagement with the spring-arbor C, so as to be capable of free rotation thereon, and at the same time is caused to engage with a spur-wheel, H, that is secured upon a centrally-located arbor, h, which carries one of or is connected with the dial-wheels I, such engagement of said wheels D and H being effected by raising the former into the plane of the latter, their teeth being thus moved into or out of engagement upon lines parallel with the axes of said wheels.

The wheel D is normally held with a yield ing pressure at the lower limit of its motion by means of aspring, K, which has one of its ends secured upon the plate B, and its opposite forked end. 70, in engagement with an annular groove, d, that is formed within a hub, (7?, which projects above the outer face of said wheel, by which means said wheel D is caused to engage with the spring-arbor disk when rotated in one direction, and to trip and fail to engage therewith when moved in the opposite direction.

The stem-arbor G is capable of being moved longitudinally to and held in two different positions for the purpose of shifting the train driven by it into and cut of engagement with the winding and setting mechanism, which result is accomplishedthrough the followingdescribed mechanism-viz:

At a point near the longitudinal center of the spring K a pin, L, is loosely contained within a suitable recess or opening in the movement-plates, one end of said pin being in engagement with the lower face of said spring, and its opposite rounded end being caused to project slightly beyond the face of the pillarplate A or the bottom of arecessed portion of said plate.

Upon the plate A is pivoted a plate, M, which has a limited motion upon its pivotal bearing, and extends over-the projecting end of the pin L, and at its pointof contact there with is provided with an inclined face, on, which, when said plate M is turned to thelimit of motion in one direction, presses said pin longitudinally toward the opposite side of the K, and when said plate is turned to the limit of its motion in the opposite direction permits said pin to be returned to its normal position by the pressure of said spring, the degree of motion thus given to said pin and spring being just sufficient to shift the wheel D into and out of engagement with the hands setting arbor-wheel H.

The cam-plate M is held normally in position to engage the hands setting mechanism with the stem-arbor by means of a spring, N, which,preferably,has a C form in plan view,

and has one end secured upon the plate A,

and its opposite free end in engagement with a recess, m, in the edge of said plate.

The stemoperated mechanism is thrown out of engagement with the dial-wheels and into engagement with the niainspring-arbor by means of a bar, 0, which has the general form in plan view of a bell-crank, is pivoted at or near its longitudinal center with one arm extending slightly over the outer face of the cam-plate M. Said arm 0 has a breadth of about one-sixteenth of an inch, and its end is formed upon a line which is concentric with the axis of said bar, and engages with a pin, mflthat projects outward from said cam-plate. The bar 0 has alimited motion upon its axis, and when the hands-setting train is in engagement with the stem-arbor, its arm 0 is at the outer limit of its motion, and the pin in engages with the inner edge of said bar immediately adjacent to the end of said arm, as shown in Fig. 2; If, now, said bar 0 is moved to the opposite limit of its motion, its arm 0 will carry inward said pin on until, by the rotation of the cam-plate M, said pin passes out ofengagement and bears against the end of said arm, when further motion of said cam-plate will cease and said parts be locked in position, as seen in Fig. 1, the winding-arbor being in engagement with the stem-arbor.

The stem-arbor G has itsinner end,g, squared and loosely fitted into the correspondingly.- shaped axial opening of the pinion F, and such engaging parts have sufficient length to enable said arbor to be moved longitudinally about one eighth of an inch without disengagement from said pinion. \Vithin said pinion is placed a pin, I, which loosely fills the same, is provided at its inner end with a head, p, and has such length as to cause it to fill the space between the inner end of said pinion and the adjacent end of said arbor when the latter is moved to the outer limit of its motion,

-while when said arbor is moved to the inner limit of its motion, said pin will be carried in bar to the position shown in Fig. 1.

As before shown, the engagement of the pin in with the end of the arm 0 of the bar 0 causes said parts to be locked in position to engage the stem and winding arbors, and} therefore it is necessary to provide means whereby said parts may be returned to their normal positions as soon as said stem-arbor is drawn outward. This is effected by means of a spring, Q, which is secured at one end upon the plate A and at its opposite end bears upon the part of said bar Olongitudinally opposite to the arm 0, and operates to automatically move said bar to the position shown in Fig. 2 as soon as it is relieved from the pressure of said stem-arbor.

When the movement is cased, it is necessary that the stem-driven train should be normally in position for setting the hands, and only held out of engagement with the dial-wheels in consequence of the position of the stemarbor at the inner limit of its motion, which position is natural and enables said arbor to perform the additional office of a push-pin. When, however, the movement is separated from the case, it is necessary that said stemoperated train should be ordinarily in engage ment with the winding-arbor, and to enable such to be done the spring Qis pivoted to the plate A, instead of being rigidly attached thereto, and at a point between such pivotal bearing and its opposite end is provided with a lug, g, which projects outward to the pe riphery of said movement-plate and engages with the case center It, such engagement causing said spring to be held in position to bear against the bar with all pressure necessary for moving said bar to normal position;

but when said movement is removed from its case, said lug (1 being no longer impinged, said spring is left free to swing outward and no longer exerts pressure upon said bar, and the latter may then be placed in and will maintain the position shown in Fig. 1, with the stem-operated train in engagement with the windingarbor. Upon placing the movement in a case again the spring Q will be caused to automatically resume its function, and will operate precisely as though not capable of release, as described.

In order to adapt the movement to open face or hunting styles of case provision is made within the plates for the placing of the wheel E at either side of the wheel D and for journaling the pinion F in position to engage with the latter, the bearings for said pinion being precisely one-fourth of the circumference of the movementplates apart.

When the pinion F is shifted to its second position, the longitudinal movement of the stem-arbor is communicated to the bar 0 by means of a second similarly-shaped bar, S, which is pivoted to the plate A, and has at one end a stud, s, that projects downward to position to be engaged by the pin P, while the opposite end of said bar bears against the inner edge of the outer end of said bar 0, by which arrangement the inward thrust of the stem-arbor is communicated to and causes precisely the same motion of said bar 0 as when the parts are arranged in the manner before described.

Having thus described myinvention, what I claim is 1. As an improvement in stem-winding and hands-setting watches, a winding and hands setting train which is adapted to be placed in engagement with the winding-wheel by the movement of a stem-arbor, and is normally in engagement with the dial-wheels only when the movement is in a case, substantially as and for the purpose specified.

2. As an improvement in stem winding and setting watches, a winding and hands-setting train which is adapted to be placed in engagement with the winding wheel by the movement of a stem-arbor, and is held normally in engagement with the dial-wheels by a spring which is operative for such purpose only when the movement is in a case, substantially as and for the purpose shown.

3. As an improvement in stem winding and setting watches, the combination, with a winding and hands-setting train, of a spring which operates to hold said train normally in engagement with the dial wheels when the movement is in a case, and is inoperative for such purpose when said movement is removed from its case, substantially as and for the purpose shownand described.

4. As an improvement in stem winding and setting watches, a winding and hands-setting train which, when the movement is cased, is normally held in engagement with the di-alwheels, and when said movement is removed from its case is automatically relieved from constraint and free to engage with the winding-wheel, substantially as and for the purpose specified.
