STEM WINDING AND SETTING MECHANISM FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 493,642, dated March 21, 1893. Application filed February 9, 1892. Serial No. 420,911. (No model.)

To all whom it may concern: mechanism, I have shown in the drawings and Be it known that I, JOHN W.

This pinion ing mechanism in which I have embodied my is journaled by means of asleeve hubj which 5 45 invention in one practical way, and the paris mounted in a suitable bearing in a dependticular improvements which I believe to be ing arm a of the front plate, as seen in Fig. 2, new and Wish to secure by Letters Patent will and inside of the pinion is a similar dependthen be more distinctly defined in the claims. ing arm a which serves to hold the wheel in As the main features of the watch may be place, and which is provided with an aperr40 50 of any usual construction and my invention ture to permit the arbor stem to move back relates only to the hand-setting and winding and forth and at the same time rotate therein.

Just inside the pendant arbor stem and in line therewith is a vertical arborK, journaled so as to have a certain amountof vertical sliding movement; the lower end of this arbor extends through and a little beyond the back plate, and terminating in a conical extremity It, as seen in Fig. 2. A pinion L, is secured to the upper end of this arbor K, by means of a screw pin Z; b it between the pinion and the arbor is arranged the inner and free end of a Hat spring M, the pin Z passing down through this spring and the otherend of the latter being fastened to the front plate near its outer edge as seen in Fig. 1. Apinion N, is also fixed on the arbor K, near its lower end just within the back plate, and engages with the winding gear 0. A pinion O, is mounted on the front plate by means of a journal pin 0 set in the latter about in line with the pendant and just within the pinion L; the bearing aperture of this pinion is cut out so as to form a central opening 0 considerably larger than the journal pin, thus providing for lateral movement of the pinion on its journal. A gear pinion P, is also mounted on the upper side of the front plate by a journal pin 23 set therein and is arranged to engage with the alarm wheel G. The idler O, is between the pinions P and L, but its journal is not in line with the journals of the latter, but is a little inside thereof, as seen in Fig. 1. The spring M, acts to hold the arbor K, normally in its lower or back position, as seen in Fig. 2. In this position the winding pinion N, is below the plane of engagement with the driving pinion on the pendant arbor stem, as shown in said figure, and in this adjustment the rotation of the pendant arbor will rotate the upper pinion L, only. This pinion L, is in engagement with the idler O, and as the latter has a lateral movement on its journal the turning of the pendant arbor in one or the other direction, thereby rotating the pinion L, in one or the other direction, will first move the pinion 0, into engagement with either the gear wheel E,or the pinion P, and then rotate the one or the other, by means of which the hands will be set as will be readily seen.

It is obvious that for winding the watch it will be necessary to adjust the mechanism so as to throw the setting gear out of engagement with the driving pinion on the pendant arbor stem, and bring the winding pinion N, into engagement therewith. This is efiected by a peculiar device operated by the pendant arbor, when pushed inward, to slide the arbor K, vertically, thereby lifting the pinion L, out of engagement with the driving pinion J, and bringing the pinion N, into engagement therewith. This device is in its main part a plate Q, which is arranged to lie on the back plate just about parallel with the pendant arbor. It is provided with a long spring (1 curved to correspond with the edge of the back plate, extending alongv the same and fastened at its outer end thereto by a ceases screw g; on the opposite edge the plate is extended outward until its edge (1 is brought underneath the headof a screw g by which the plate is held to the back plate, but at the same time is permitted to move in and out. This plate extends inward to the lower end of the arbor K and then is dropped down slightly, so that its inner end q is bent downward, the bend providing an inclined face (1 as seen in Fig. 2. WVhen in normal position, as seen in Fig. 2, this dropped portion of the plate is below the lower end of the arbor in its lower adjustment; it is obvious however, that if the plate is pushed in the incline or bend will be brought into contact with the conical end of the arbor and raise the latter causing the arbor to slide upward. This movement effects the desired change in the adjustment of the gear pinions, bringing the winding pinion N, into engagement with the driving pinion J and disengaging the pinion L. therefrom, the spring M, yielding to permit this movement. At'the outer end of the plate Q, there is provided an arm R, which extends directly upward at right angles to the plate for a little distance, as seen in Figs. 5 and 6. This arm may be in one piece with the plate or separate therefrom as may be desired. Itis outside of the back plate and projects into the ring center which is cut out for this purpose; then it is bent outward at right angles for a little way and then directly upward again, the upper end being somewhat enlarged and arranged within a suitable recess 2" in the ring center at the junction of the pendant therewith, which is sufficiently large to permit some movement of this end of the arm out and in. It will be seen then that the arm R, is composed of three sections,ashort, straight section 1', extending at right angles to the sliding plate directly toward the pendant arbor, a second short section 1" extending directly outward at right angles to the former and a third section r arranged at right angles to the latter and so parallel with the first section 0'. Now it is obvious if a pressure is brought to bear upon the upper end of this arm B, it will be forced inward and thereby move the sliding plateinward to raise or slide the arbor K. in the direction of its length by the action of the bend or incline, in the plate, on the lower end of the arbor. This pressure on the arm is effected by the sliding movement of the pendant arbor, the stem of the latter being carried through the upper end of the arm, as seen in Fig. 2, so that when the arbor is pushed inward the shoulder at the beginning of the stem will strike the arniand force it inward. I have shown in the drawings a desirable way of mounting the pendant arbor stem in this arm, it is effected by means of a disk S, which is set in a suitable aperture r in the arm; this disk has a central perforation sshaped like the arbor stem, so as to receive the latter and permit it to slide back and forth therein. Around the disk is a circumferentially V shaped groove s and the edge around the opening r is V shaped to fit this groove, as seen in Fig. 2. The opening r is elongated, as seen in Fig. 5, which permits some slight movement of the disk in its seat to prevent any opening of these parts. This however, is only a desirable device for mounting the arm on the stem of the arbor, and any other suitable means may be employed.

In normal adjustment, it will be noticed that, as already described, the devices are in position for setting the hands, simply by turning the pendant arbor in one direction or the other. When it is desired to wind the watch the pendant arbor is pushed inward, thereby sliding the arbor K. in the direction of its length as described, thus disengaging the setting pinion L from the driving pinion on the arbor stem and bringing into engagement therewith the winding pinion N, when of course, the watch may be wound without disturbing the hands. But it is not desirable in carrying a watch to have the hand-setting mechanism in constant engagement, but rather the winding mechanism. It will be understood that the sliding pendant arbor is provided with the usual catch or stop to secure it in position when thrustinward. The adjustment of the parts for ordinary use then Will be to thrust the arbor inward until its stop is engaged, when the setting gear will be out of position and the winding gear in proper engagement, as seen in Fig. '7. \Vith this arrangement the watch may be wound at any time, but, in order to set the hands, the arbor must first be pulled out, when the springs will bring the parts into the adjustment seen in Fig. 2, for hand-setting.

It will be understood of course, that the setting of the hands by the use of the pinion P cannot be done, while the alarm mechanism described in my prior application is set for operation, which of course would only be occasionally, so that practically this pinion is available for setting the hands in one direction, because the alarm mechanism is thrown out of working adjustment the greater portion of the time.

It will be noticed that I have here provided an adjusting device for the winding and setting mechanism that is entirely outside of the watch movement, being fastened on the outside of one of the plates of the latter, and lying wholly outside thereof and operated from the outside thereof. This brings the device within easy reach and operation and also permits it to be readily removed without disturbing in any wise the ordinary works of the watch.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a stem winding watch, an arbor mounted to slide in the direction of its length, in combination with a winding pinion and a setting pinion both mounted thereon, an adjusting device arranged on the outside of the movement, adapted to move the said arbor lengthwise in its bearings, and a sliding pendant arbor, arranged to actuate said adjusting device outside of the movement, substantially as described.
