STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 370,929, dated October 4, 1887.

Application filed October 13, 1886.

and setting watches, and has for its object to enable the wheel which communicates motion from the winding-bar in the pendant to either the winding or the hands-setting mechanism to be operatively connected with either the winding'wheel or the dial-train by a movement substantially at right angles with its axis of rotation, instead of by the swinging movement of two shiftable wheels carried by a swinging yoke, as heretofore; and to this end it consists, mainly, in the combination of a winding-train and a dial-train, each of which is composed entirely of wheels which are not shiftable like those carried by a swinging yoke, a wheel which is capable of rotation by the pinion rotated by the winding-bar, and is movable between said trains substantially at right angles to the axis of its rotation, and is capable of engaging said trains alternately, a spring which,when free to act, holds said wheel in engagement with one of the members of the winding-train, and a spring-impelled lever which normally overcomes the pressure of said spring and holds said wheel in engagement with one of the members of the dial-train, and is adapted to be made inoperative by the winding-bar when the latter is capable of an endwise movement, or by a slide on the watchplate when the winding-bar is not capable of such movement, all of which I will now proceed to describe. I

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front view of the plate of a watch-movement having my improvements, showing the shiftable wheel in engagement with one of the members of the winding-train. Fig. 2 represents a back view of the plate, the parts being in the position shown in Fig. 1. Fig. 3 represents a front view of the plate, showing the shiftable wheel in engagement with a member of the dial-train.

resent front views of apart of the plate, showing the slide which moves the shiftable wheel in a watch in which the winding-bar is not movable endwise. Fig. 7 represents a front view of a part of the plate with the shiftable wheel and its retaining-plate removed. Fig. 8 represents an enlarged view of the slide 1;. Figs. 9, 10, 11, 12, and 13 represent detail views.

In carrying out my invention I dispense with the usual oscillatory yoke which carries the intermediate wheels, whereby motion is communicated from the wheel meshing with the pinion on the winding-bar, respectively, to the winding-wheel and dial-train. I provide a dial-train composed of the common pinion, a, the wheel I), meshing therewith and journaled on the plate d, as usual, and the wheel 0, which, instead of being journaled in an oscillatory yoke or otherwise adapted to be moved into and out of engagement withthe wheel b, as heretofore, is journaled on a fixed bearing, and is in continual engagement with the wheel I).

e represents the winding-wheel, and f a wheel journaled on a fixed bearing and in continual engagement with the winding-wheel, said wheel and the winding-wheel constituting a winding-train, the wheel f being a substitute for the shiftable intermediate winding-v wheel, which is usually carried by the oscillatory yoke above referred to.

g represents the winding-bar, and h the pinion, which is rotated thereby, said pinion having in this instance an arbor journaled in a block, i, on the plate d, and provided with a squared socket, which receives the squared end of the winding-bar, so that the bar is capable of an endwise movement, as usual in watches in which the connection of the winding-bar with the winding and hands-setting wheels is changed by an endwise movement of said bar.

j represents the wheel which is in continual engagement with the pinion h and receives motion therefrom. Said wheel j corresponds to the crown-wheel, which, in a watch having a swinging yoke, is journaled on a fixed bearing, and is in continual engagement with the two swinging wheels heretofore used in place of the wheels 0 and f.

My improvement involves afurther departj at the under side of the guiding-plate 7c.

ure from the construction heretofore employed, in that the wheelj is notjournaled on a fixed bearing, and is not engaged at the same time with the wheels 0 and f, but is capable of an edgewise movement substantially at right augles with the axis of its rotation, and is of such size relatively to the space between the wheels 0 f that it can engage with but one of said wheels at a time, its capability of edgewise movement enabling it to be engaged with either the wheelf or the wheel 0, and thus to communicate motion from the winding bar either to the windingtrain or to the dial-train.

The wheelj is mounted on a stud, j, which is affixed to a circular guiding plate or disk, Said guiding-plate is adapted to slide in an elongated recess, Z, Figs. 7 and 11, in the plate (2, the width of the recess being such that the guiding-plate fits closely in it and is guided by its edges. A U-shaped spring, a, is placed in a smaller recess formed in the bottom of the recess Z, one end of said spring being engaged with an indentation, cl, in said smaller recess, while its other end is engaged with the arbor A cap, 1n, rigidly secured to the plate (1, projects over the wheels j,f, and c, and retains them in place on the studs on which they rotate. \Vhen said spring a is free to act, it forces the wheelj into engagement with the wheel f of the winding-train, as shown in Fig. 1, and thus causes the rotation of the windingbar in one direction to operate the winding mechanism, the spring permitting the wheel j to yield and ratchet on the wheel f when the windingbar is rotatedin the opposite direction, asmore fully described hereinafter.

In a watch in which the winding-bar is movable endwise to shift its connection from the winding to the hands-setting mechanism, or vice versa, the wheel j is in engagement with the wheel f of the winding-train when the winding-baris pushed in, devices (next described) being provided,which,when the wind ing-bar is pulled outwardly, operate automatically to move the wheel j against the pressure of its spring a into engagement with thewheel c of the dial-train. Said devices are in this instance a lever, 9, pivoted at q to the plate cl, and having at one end a cam-shaped slot, 0', which receives the stud or arbor j on the plate 70', and a spring, a, secured at tto the plate and bearing against the end of the lever 12 opposite to that end which contains the slot 1'. A pin, a, longitudinally movable in the pinion it, bears against the lever 11 and against the inner end of the winding-bar g, and when the winding-bar is pushed in said pin is caused by the winding-bar to hold the leverp in the position shown in Fig. 2, so that the enlarged end of the slot 1' receives the arbor j of the plate It and permits the spring a to act and hold the wheel j with a yielding pressure in engagement with the winding-train, the arbor 9" being free to move in the enlarged end of the slot 0' in the direction required to permit the teeth of the wheel j to move alternately into and out of engagement with the wheel f of the winding-train, and as the wheel j is held in contact with the wheelf with a yielding pressure, it follows that the wheel j can yield or ratchet on the wheel f, as above stated, as shown in Fig. 1. When the winding-bar is drawn outwardly,the pin it releases the lever 11, and the spring 5 then forces said lever to the position shown in Fig. 4- and causes the side 2 ol' the slot '1' to bear on the arbor j of the plate It and force said wheel against the pressure of the spring a into engagement with the wheel a of the dial-train, the wheel 7' being thus normally held in its hands-setting position and locked so that it cannot yield or ratchet by the engagement of the arbor j with the narrower end of the slot 0*, as shown in Fig. t. When the winding-bar is not movable endwise, the springpressed shifting-lever 1) may be moved by a slide, a, fitted in a groove in the plate (2 and projecting at its outer end through an aperture in the case-center, so that when the case-bezel is opened it may be moved out or in, as in many styles of pendant setting watches now in use, the outer end of said slide having a lip whereby it may conveniently be manipulated.

In the slide 12 is a slot, 10, which receives a stud, a", on the shorter arm of the lever 19. One side of said slot is formed to act as a cam, and the stud 0c is pressed against said cam-shaped side by the spring a. \Vhen the slide 1; is in the position shown in Fig. 5, the projection 3 011 the side of its slot, against which the stud x of thelevcr p bears, holds said stud and lever in the inoperative position of the latter, so that the wheelj is held by its spring a in its winding position. \Vhen the slide 1) is drawn outwardly, as shown in Fig. 6, the enlargement 5 of its slot permits the lever p to assume its normal position, and thus shift the wheel j into its setting position.

I prefer to provide each watch-movement to which my invention is applied with a slide, 12, so that the movement can be usedinterchange' ably with a case having a longitudinally-movable winding-bar, or with one in which the winding-bar is not movable longitudinally. The slot to is enlarged atits outer end, so that when the movement is used with a case having a longitudinally-movable winding-bar the slide may be pushed inwardly until the en largement 4 receives the stud a; of the lever 12, as shown in Fig. 1. The slide is inoperative while it remains in said position, so that it does not interfere with the operation of thelever 1) by the winding-bar. The slide is, moreover, when in this position so nearly within the margin of the plate (Z that it will not interfere with the case to which the movement is applied.

It will be observed that by the described improvements the construction of the winding and setting mechanism is considerably sim plified and the expense is correspondingly re duced.

In stating that the wheel j moves at right angles to the axis of its rotation, I do not mean that it necessarily moves in a straight line at right angles to said axis, nor exactly or absolutely at right angles thereto.

I claim- 1. In apendant winding and setting watch, a shiftable wheel driven by the winding-pinion and without positive pivotal attachment, which is caused to engage with the windingtrain or with the handssetting train by the endwise movement of the winding-bar, and which, when engaged with the winding-train, is held by a yielding pressure, but when engaged with the hands-setting train is positively locked in such position, as shown and described.
