STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 57 5,168, dated January 12, 1897.

Application filed October 15, 1894. Serial No. 525,922. (No model.)

T0 at whom it may concern.-

Be it known that 1, WILSON E. PORTER, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Stem -Winding and Stem- Setting \Vatches; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specifr cation, and represent, in-

Figure 1, a view in side elevation of a watchmovement constructed in accordance with my invention, and showing the main and intermediate winding-wheels; Fig. 2, a similar re verse view showing the minute-wheel and the intermediate setting-wheel; Fig. 3, an enlarged broken plan view showing the movement-plates and the longitudinally-movable arbor mounted therein and carrying the intermediate winding and setting wheels; Fig. 4, aview in vertical section showing the said arbor and wheels and showing also the winding and setting wheel and arbor, the parts being in their normal positions, inwhich the watch is adjusted for winding; Fig. 5, a similar view showing the conversion of the watch for setting by the inward movement of the winding and setting arbor and the consequent movement of the arbor carrying the intermediate winding and setting wheels; Fig. 0, a View, partly in plan and partly in transverse section, on the line a b of Fig. 4.

My invention relates to an improvement in stem-winding and stem-setting watches, the object being to provide a simple, compact, and convenient construction adapted to be produced at a low cost for manufacture, containing few parts, and not liable to derangement.

TVith these ends in view myinvention consists in a stem-winding and stem-setting watch having certain details of construction and combinations of parts, as Will be hereinafter described, and pointed outin the claims.

In carrying out my invention I mount a longitudinally-movable or sliding non-rotatable arbor A transversely between the upper edges of the movement-plates B B of the watch, and

in line with but at a right angle to the inner end of the winding and setting arbor 0 thereof. One end of this arbor is reduced to form a cylindrical hub or bearing A and a shoulder a, while the other end is reduced to form a flattened hearing or hub A and a shoulder a". The central portion of the arbor is thus virtually enlarged. The flattened hub A prevents the arbor from rotating, for which purpose the said hub may have any irregular form instead of the form shown. The same effect will be accomplished by flattening the hub A or making it otherwise irregular in form, and if desired both hubs may be adapted to resist the rotation of the arbor. The shoulders a and a engage with the inner faces of the movement-plates and limit the reciprocating movement of the arbor.

The hub A, as herein shown, has secured to it by means of a screwD the intermediate winding-wheel E, which meshes into the main winding-wheel E, the same being of any ordinary construction. On the other hand, the hub A has secured to it by means of a screw D the intermediate setting-wheel F, which meshes into the minute or dial wheel F,which may be of any approved construction. Both of the intermediate wheels are engaged, though notat the same time, with the main winding and setting wheel G, the lower face of which rests upon the edges of the movement-plates B B, which are thereto cut away to form bearing-surfaces b b. It will be seen that the wheel G is located in a horizontal plane, and therefore at a right angle to the wheels E and F. The said wheel G has a square'cen tralopenin g receiving the squared lower end C of the rotatable and longitudinally-movable winding and setting arbor C, which is mounted in the usual manner in the watch-pendant (not shown herein) and which is thus coupled for rotation with the said wheel, of which, however, it is free as to longitudinal movement.

For the purpose of moving the arbor A longitudinally to throw the intermediate winding-wheel out of engagement with the main winding and setting wheel and to move the intermediate setting-wheel into engagement with the said main winding and setting wheel I construct the arbor with a transverse wedgeshaped notch A, one inclined face of which forms an inclined. operating-face and is engaged by a bevelpoint C forming the termination of the squared portion 0 of the winding and setting arbor. A spring ll, fitting into a slot a formed transversely in the arbor at the bottom of the wedgeshaped notch therein, and hearing at its ends upon one of the movement-plates 13, holds the arbor in position for maintaining the intermediate winding-wheel E in engagement with the main winding and setting wheel G and the intermediate setting-wheel F out of engagement with the said winding and setting wheel G, as clearly shown in Fig. i of the drawings. When, however, the winding and setting arbor is pushed inward, its tapered point C coacts with the adjacent beveled face of the notch A and overcomes the tension of the spring ll and causes the arbor to be moved out of its normal position and so as to throw the intern'iediate winding-wheel E out of engagement with the main winding and setting wheel G and the intermediate setting-wheel F into engagement with the said. wheel G, in which adjustment of the watch it may be set so long as the inward pressure upon the winding and setting arbor is maintained; but the moment this pressure is relieved the arbor 0 moves outward and permits the spring II to reassert itself in moving the arbor A transversely and reengaging the intermediate winding-wheel with the main winding-wheel and disconnecting the intermediate setting wheel from the main winding and setting wheel, leaving the watch normally in eondition for winding. Inasmuch, therefore, as the intermediate setting-wheel is normally out of action there is no chance of accidentally changing the set of the watch.

If desired, the parts may be constructed so that when the intermediate winding-wheel is disengaged from the windin g and setting wheel it will also be disengaged from the main winding-wheel, but that construction is not at all essential, inasmuch as the main winding-wheel revolves only when the watch is being wound. On the other hand, it is desir able that when the intermediate settin g-wheel is disengaged from the winding and setting wheel it should also be disengaged from the min ute-wheel, for otherwise the watch would be under the necessity of normally drivingthe intermediate setting-wheel, which it would do, but the load is unnecessary.

As herein shown, as before stated, the watch is normally adjusted for winding, and shifted from that into adjustment for setting.

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

llaving fully described my invention, what I claim as new, and desire to secure 'I y Iliel tors Patent, is-- 1. In a stem-winding and stem-setting watch, the combination with the nmvementplates thereof, of a non-rotatable sliding arbor mounted therein, an intermediate winding-wheel loosely mounted upon one end of the said sliding arbor adjacent to the outer face of one of the said movement-plates and nori'nally meshing into the main windingwheel of the watch, an ii'itermediate scttingwheel loosely mounted upon the other end of the said sliding arbor adjacent to the outer face of the othermovement-plate,and adapted to mesh into the minute-wheel of the watch, a winding and setting wheel, and means for shifting the said sliding arbor so as to throw the wheels loosely mounted upon it into and out of engagement with the said winding and setting wheel.

2. In a stem-winding and stem-setting watch, the combination with the movement plates thereof, of a non-rotatable sliding arbor arranged therein and having its central portion formed with an inclined operatingface, an intermediate winding-wheel loosely mounted upon one end of the said arbor adjacent to the outer face of one of the said movement-plates, and normally meshing into the main wimling-wheel of the watch, an intermediate setting-wheel loosely mounted upon the other end of the said arbor adjacent to the outer face of the other movemen t-plate, and adapted to mesh into the llliillliJO-WilGOi of the watch, a winding and setting wheel located in position to be alternately meshed into by the said intermediate winding and setting wheels carried by the said sliding arbor, a winding and setting arbor passing through the winding and setting wheel with which it is coupled for rotation, and having its inner end adapted, when it is pushed inward, to engage directly with the said inclined operating-face of the sliding arbor for sliding the same in one direction, and a spring for sliding the arbor in the opposite direction. when the winding and setting arbor is drawn longitudinally outward.

3. In a stem -winding and stcm-setting watch, the combination with the movementplates thereof, of a non-rotatable, sliding arbor mounted therein and having its central portion formed with a transverse notch haw ing an inclined operating-face, an intermediate winding-wheel loosely mounted upon one end of the arbor adjacent to the outer face of one of the movementplates, and nor mally meshing into the win ding-wheel of the watch, an intermediate setting-wheel loosely mounted on the other end of the arbor adjacent to the outer face of the other movementplate, and adapted to mesh into the minutewheel of the watch, a winding and setting wheel located in position to be itlteri'lately meshed into by the said intermediate wind ing and setting wheels carried by the said arbor, a longitudinally-movable and rotatable winding and setting arbor passing through the winding and setting wheel with which it is coupled for rotation, and having its inner end adapted to enter the said notch and engage with the said inclined operating-face for sliding the sliding arbor in one direction, and a spring for sliding the said arbor in the opposite direction.

4. In a stemwinding and stem -setting watch, the combination with the movementplates thereof, of a non-rotatable, sliding arbor mounted therein, of an intermediate winding-Wheel loosely mounted upon one end of the arbor, and normally meshing into the winding-wheel of the Watch, an intermediate setting-wheel loosely mounted upon the other end of the arbor and adapted to mesh into the minute-wheel of the Watch, a winding and setting wheel located in positionto be alternately meshed into by the said intermediate Winding and setting Wheels, a longitudinallymovable winding and setting arbor coupled With the said winding and setting wheel for rotating the same and coacting with the said sliding arbor for sliding the same in one direction, and a spring connected directly with the said sliding arbor at a point between the movement-plates and engaging with the inner face of one of the same for sliding the sliding arbor in the opposite direction from that in which it is moved by the winding and setting arbor.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
