SAFETY DEVICE FOR WATCHES.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed September 7, 1910. Serial No. 580,805.

To all whom it may concern:

Be it known that I, ANTONIO MARCANTE, a subject of the King of Italy, residing at Summit, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Safety Devices for \Vatches, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to means for securing a watch in a pocket to prevent the same from being accidentally. or surreptitiously removed from such pocket.

The object of the invention is to provide an attachment which may be clamped to the stem of a watch, said attachment having means for automatically engaging opposite sides of a pocket, so that any person not knowing how to retract the slides cannot remove the watch without causing a pull on the pocket of the wearer.

The invention consists in the safety device substantially as hereinafter described and claimed.

Of the accompanying drawings: Figure 1 is a plan view of a safety device embodying my invention. Fig. 2 is a side elevation of the same, a watch to which the device may be applied being indicated by dot- Fig. 3 represents a horizontal section through the device including both jaws. Fig. 1- represents a transverse section through one of the jaws.

Similar reference letters indicate the same or similar parts in all of the views.-

The two jaws are practically identical, each comprising a body portion 10 which may be made as ornamental as may be desired. The body is concave as at 11 so as to fit one side of the stem of a watch. The two jaw bodies are connected by screws 12, each screw passing freely through one body and fitting a threaded hole in the other body so that, by tightening up the two screws, the concavities 11 may be set up firmly so as to clamp the stem of a watch to lock the device to said watch.

In order that the device may engage the inner walls of a pocket in such manner as to prevent it, and the watch, from being sur reptitiously or accidentally removed from the pocket, a slide 13 is provided in each jaw body, said slide having an outwardly facing head 14. The inner portion of the slide fits a socket 15 in the jaw, and a spring 16 is interposed between the bottom of the socket and the inner end of the slide. Each jaw body is formed with a slot 17 through which a finger grip projects from the slide 13.

Of course by proper manipulation of the screws, the two jaws are entirely separable from each other so that they can be then assembled so as to clamp the stem of a watch between the case and the ring. lVhen clamped in position as described, the user grasps the finger grips 18 and presses them toward each other thus shortening the length of the device by withdrawing the slides 13. After the watch has been inserted in the pocket and the finger grips released, the springs 16 press the slides outwardly so that the heads thereof will engage the inner walls of the watch pocket. To remove the watch from the pocket it is only necessary to press. the handles or grips 18 toward each other, thus releasing the slide heads from the pocket, after which the watch may be readily removed for observation or winding or other purpose.

As indicated by the dotted lines in connection with the device illustrated in Fig. 2, the normal length of the device between its pocket engaging portions is such as to exceed the greatest diameter of the watch, so that when the device is applied as shown, the slides act in a plane substantially parallel with the plane of the watch face. This is necessary for practical purposes because the length of the pocket must of course be such asto permit the watch to be taken out for observation, and therefore, if the device is to engage the ends of said pocket, the engaging portions must have a capacity to spread wider than the length of the top or mouth of the pocket.

I claim:

1. A watch attachment of the character described comprising aws for clamping the stem of a watch, and pocket-engaging slides projecting in opposite directions, the normal length of the device between its pocket-engaging portions exceeding the greatest diameter of the watch, whereby said slides act in a plane substantially parallel with the plane of the watch face.

2. A watch attachment of the character described comprising separable jaws having means whereby they may be clamped upon the stem of a watch, and pocket engaging slides projecting in opposite directions, the normal length of the device between its pocket engaging portions exceeding the greatest diameter of the watch, whereby said slides act in a plane substantially parallel with the plane of the watch face.

3. A watch attachment of the character described, comprising a pair of adjustable jaws having means for closing them on the stem of a watch, slides movable in opposite directions, and springs for pressing the slides outwardly, the normal length of the device between its pocket-engaging portions exceeding the greatest diameter of the watch, whereby said slides act in a plane substantially parallel with the plane of the watch face.

4;. A watch attachment of the character described comprising a pair of elongated bodies provided with jaws connected to each other by screws whereby they may be adj usted to clamp them on the stem of a watch, slides mounted in the jaw bodies and having finger pieces projecting from said bodies, and springs normally pressing the slides outwardly, the outer ends of the slides having means for engaging the inner walls of a pocket, the normal length of the device between its poeket-engaging portions exceeding the greatest diameter of the watch, whereby said slides act in a plane substantially parallel with the plane of the watch face.

In testimony whereof I aflix my signature in presence of two witnesses.
