Specification of Letters Patent.

Patented Feb. I8, i919.

Application led J'uly 26, 1918. Serial No. 246,883.

To all whom it may concern.'

Be' it known that I, CHRISTOPHER C. SMITH, a citizen of the United States, residing at Eugene, in the county of Lane and State of Oregon, have invented certain new and useful Improvements in Devices for Winding Watches, of which the following is a specification.

The object of this invention is to provide a simple and eiicient device by the use of which watches may be readily wound notwithstanding that the' corrugations on the head of the stem are badly worn, or that the fingers of the person winding the watch may happen to be cut or sore. The invention seeks to provide a device which may be easily fitted over the head of the watch stein and firmly engage therewith so that uponv turning of the device the watch will be wound.

The invention is illustrated in the accompanying drawings and consists in certain novel features which will be particularly pointed out in the claim following the description.

In the drawings:

Figure 1 is a plan view of a watch showing my improved device in position thereon;

Fig. 2 is an enlarged elevation, partly.Y broken away, of the improved device show ing the parts in the position assumed when the device is not engaged over a watch stem;

Fig. 3 is an elevation showing the parts in the positions assumed when the watch stem is engaged;

Fig. 4 is a detail section on the line l--4t of Fig. 2;

Fig. 5 is a detail section on the line 5-5 of Fig. 3;

Fig. 6 is a detail perspective view of the compression ring.

In the drawings, the reference numeral 1 `indicates a watch of the usualfform provided with a winding stern 2. In carrying out my invention, I employ a tube having one end 3 closed and its opposite end open while longitudinal slits 4 are formed in the circumferential wall of the tube and extend from a point near the closed end thereof through the open end of the same, as clearly shown. At its open end the tube is expanded to provide the enlargement 5 having a concave inner surface, as shown at 6. whereby it may readily lit around the head of the watch stem, as shown in Fig. l. The said inner concave surface 6 is preferably corrugated so as to most efciently engage the corrugated head of the watch stem. Upon the outer surface of the circumferential wall of the tube, I provide the longitudinal ribs 7 which are disposed alternately with the slits 4 and serve guides for the compression ring 8 which is provided on its inner surface with longitudinal grooves 9 adapted to engage the said ribs. The outer surface of the compression ring 8 will preferably be knurled or milled so that it may be readily grasped and manipulated. In the closed end of the tube, I secure an eye 0r ring 10 whereby the device may be hung upon a watch chain and utilized as a charm.

It is thought the use of the device will be readily understood. When a watch is to be wound, the open end of the tube is engaged over the head of the watch stem and the compression ring 8 then pushed toward the said open end, it being understood that a spring temper will be imparted to the mate` rial of the tube so'that the several longitudinal tongues or sections resulting from the provision of the slits 4 will tend to separate or expand, as shown in Fig. 2. When the ring 8, therefore, is pushed toward the open end of the tubeto the position shown in Fig. 3, the jaws provided by the expanded or enlarged portions 5 will be forced into close engagement with the head of the watch stem and will be clamped thereon so that if the tube be rotated the stem will 'follow the movement and the watch will be wound. When the watch has been wound. the comv pression ring is withdrawn to the upper ends of the ribs 7, as shown in Fig. 2, whereupony the tongues will separate and the device may be withdrawn from the watch stem.

The device is exceedingly simple in its construction and it will be found eilicient in operation. It. is not apt to get out of order and may be constructed of any preferred material and ornamented to a greater or less extent. By the use of the device a watch may be easily wound after the corrugations on the head of the stem have been badly worn or when the owner of the watch may happen to have sore or cut fingers and wrist watches may be wound by the use of this device without being removed from the wrist. The device furnishes a larger and,

member of the Watch so that overwinding of the Watch is easily avoided.

Having thus described my invention, what is claimed as new is:

A device for the purpose set forth oomprising a tube closed at one end and' open at the opposite end and having longitudinal slits extei'rdinig from points near its closed end through its open end, the tube beingr further provided with externallongitudinal ribs alternating with said slits and having an internal seat for a Watch stein at its openend7 and a ring encircling the tube'and eHeot rotation of the tube and the watch Y stein engaged thereby.

Intestmiony whereof I aiiiX my signa-turc.
