STEM-WINDING WATCH.

7 SPECIFICATION forming part of Letters Patent No,325,568, dated September 1, 1885.-

(No model side of the ratehet-bridge detached from its connecting parts. Fig. 2 is a like view of the lower side of the same. Fig. '3 is a perspective view of the click and yoke spring, and Figs. 4. and 5 are plan views, from the dial side, of a watch-movement containing the said parts, and show, respectively, the stern-train in engagement with the windingarbor wheel and with the dial-wheels.

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

The design of my invention is to increase the efficiency, to lessen the expense, and to simplify the construction of stein-winding and hands-setting watches; to which end my i11- vention consists, principally, in a spring which is confined at or near its longitudinal center within a pivoted vibratable bearing, and at one end bears, upon and holds a click in engagement with the windingwheel, and at its opposite end hears upon the winding-yoke and tends to hold the same at one limit of its motion, substantially as and for the purpose hereinafter specified.

It consists, further, in a combined cliekspring and winding-yoke spring, which, at or near its longitudinal center, is engaged by and confined within the longitudinallysplit end of a pivoted vibratable stud, substantially as and for the purpose hereinafter shown.

It consists, further, in a combined clickspring and winding-yoke spring, which, at or near its longitudinal center, is secured to or within a pivoted vibratable stud, substantially as and for the purpose hereinafter set forth.

It consists, further, in an improvement in stem-winding and hands-setting movements, in a bridge which operates to hold in position the winding or ratchet wheel, the click, and

by means of. a single screw, substantially as and for the purpose hereinafter shown.

It consists, finally, in the combination of the bridge, the winding or ratchet wheel, the click, and the combined click spring and yokespring, substantially as and for the purpose hereinafter set forth.

In the annexed drawings, A represents the pillar or dial-plate of a watch, within which and within another plate (not shown) is journaled a mainspring -arbor, B, that projects slightly above said plate A, and carries upon its projecting squared portion a toothed wheel, C, that performs the double office of a winding-wheel and a ratchet-wheel.

Journaled within asuitable bearing between the edges of the movementplates is a pinion, D, which is adapted to receive the end of a stem-arbor, E, and to be rotated by the same, which pinion meshes with and imparts motion,

to a wheel, F, that is journaled upon the plate A by means of a screw G. v

Upon the upper end of the screw G is pivoted centrally a yoke, H, which, preferably, has the form in plan view shown, and upon one end has pivoted upon its lower face a pinion, I, that meshes with the toothed wheel F, and by the oscillation of said yoke may be caused to mesh with the windingwheel C,.as shown in Fig. 4, in which position the rotation of the stem-arbor E in the right direction will cause the springarbor B to be rotated and the mainspring wound.

Upon the end of the yoke H, opposite to that upon which is pivoted the pinion I, asecond pinion, K, is pivoted to its lower face, and meshes with and receives motion from the wheel F, and by the movement of said yoke upon its pivotal hearing may be caused to engage with one of the dial-wheels L, as shown in Fig. 5, so as to enable the hands of the watch to be moved by the rotation of the stem- IOO arbor E, such engagement with said dialwheels being secured at the instant when the stem-driven train is removed from engagement with the winding-whcel, while by a reverse movement of said yoke, said train is disconnected from said dial-wheels and mengaged with said winding-wheel.

The normal position of the yoke H is with the pinion I in engagement with the windingwhcel O, and it is held in such position with a slight pressure by means of a spring, M,one end of which bears against the outer edge at the end of said yoke adjacent to said windingwheel.

The spring M is made from round wire slightly flattened by rolling, and has in plan view a plain curved form. At or near its lon gitudinal center said spring has attached a round stud, N, the projecting ends of whichare pivoted within the plate A and within a bridge, 0, said stud thus forming a fulcrum for said spring which is free to turn upon said fulcrum to adapt itself to variations in the positions of the connecting parts.

The spring M is preferably connected with the stud N by being inserted within a transverse slot, at, that is formed in the end of the latter, after which the metal at the sides of said slot maybe punched inward and caused to fasten said spring in place; but any other means for fastening said parts together may be employed in lieu of that described.

The end of the spring M bears upon a click or pawl, I, which is pivoted between the plate A and bridge 0, and by the action of said spring is held with a yielding pressure in engagement with the teeth of the winding-wheel (J and operates in the usual manner to prevent the backward movement of the spring-arbor 13, while permitting the same to be freely rotated in a forward direction.

The bridge 0, as seen in the drawings, extends over the winding or ratchet wheel 0, and holds the same in place, and, as before stated, furnishes bearings for the outer end of the fulcrum-stud N and for the outer pivot of the click 1?. Said bridge has a bearing at one end upon the plate A, and is held in position thereon by means of a single screw, 0, the withdrawal of which screw enables said bridge, click, winding-wheel, and the click and yoke spring to be removed. If desired, an ordinary dowel-pin may be inserted within said bridge and adapted to engage with a corresponding opening in said plate; but it is believed that said screw will alone hold said bridge with sufficient firmness.

It will be seen that the spring M performs the office of two heretofore separate springs, and that in consequence of its pivoted fulcrum much greater freedom of motion is secured than would otherwise be obtainable.

Having thus set forth the nature and merits of my invention, what I claim is- 1. A spring which is confined at or near its longitudinal center, within a pivoted vibratable bearing, and at one end bears upon and holds a click in engagement with the winding-wheel, and at its opposite end bears upon the winding-yoke and tends to hold the same at one limit of its motion, substantially as and for the purpose specified.

2. A combined click-spring and windingycke spring, which, at or near its longitudinal center, is engaged by and confined within the longitudinally-split end of a pivoted vibratable stud, substantially as and for-the purpose shown.

3. A combined click-spring and windingyoke spring, which, at or near its longitudinal center, is secured to or within a pivoted vibratable stud, substantially as and for the purpose set forth.

4. As an improvement in stem winding and hands-setting movements, a bridge which operates to hold in position the winding or ratchet wheel, the click, and the click and yoke spring, and is itself held in position upon and connected with the movement-plate by means of a single screw, substantially as and for the purpose specified.

5. As an improvement in stem -winding and handssetting movements, a yoke which operates to hold in position the winding or ratchet wheel, the click, and the click-spring, and it is itself held in position upon and corn nectcd with the movement-plate by means of a single screw, substantially as and for the purpose shown.

6. The combination of the bridge, the winding or ratchet wheel, the click, and the combined click-spring and yoke-spring, substanstantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of February, 1885.
