WATCH -BOW.

SPECIFICATION forming part of Letters Patent No. 415,956, dated November 26, 1889.

Application filed March 8, 1889- Serial No.302,422- (No model.)

To all whom it may concern:

Be it known that I, HERMAN T. BUCK, of New York, in the county and State of New .York, have invented a certain new and usematter for pickpockets to twist the ring out of the stem, and thus remove the watch from its chain or guard.

I will describe in detail a safety attachment embodying my improvement, and then point out the novel features in a claim.

In the accompanying drawings, Figure l is a side elevation, on an enlarged scale, showing a portion of awatch-case and a stem having a safety attachment embodying my improvement applied thereto. Fig. 2 is a view on a similar scale, and showing avertical section of a portion of the stem and of a ring embodied in my improvement.

Similar letters of reference designate corresponding parts in both figures.

A designates a portion of a watch-case, and B the stem thereof, which may be of the usual construction.

O designates the ordinary push-piece for winding the watch or opening the case.

D designates a ring surrounding the stem B loosely below the push-piece C E designates the ordinary watclrring. In the sides of the ring D are formed apertures a, through which the end portions of the ring E extend. The ring D is provided internally with cavities b. In the stem B are also formed cavities or recesses 0, into which the inner ends of the ring E extend when the latter is in position on the stem. The end portions of the ring E extend through the cavities b, and Within the cavities said portions are provided with projections e.

These projections are of such extent laterally that they cannot be passed downwardly through the openings at in the sides of the ring D. In the present example of my improvement I have shown such projections to consist of pins, which may be driven through suitable holes in the ring.

It will be readily seen that if a twisting motion be given to the ring E it will not operate to "detach the. ring from the stem, for the reason that the projections 6 will prevent the ring from being detached from the ring D. Even if the end portions of the ring E should be twisted out of the recesses c in the stem, the ring D will still operate to re tain the ring E upon the stem, because the endwise movement of the ring D upon the stem, so as to withdraw said ring therefrom, would be prevented by the push-piece O.

In assembling the parts the ring E is first secured upon the ring D, and the ring D is passed downwardly over the stem until the ends of the ring E enter the recesses c in the stem, into which they will be sprung by the resilience of the ring E. The cavities b in the ring D are of sufficient extent laterally to admit of a considerable movement of the projections e rearwardly, in order to admit of the ring E being slid downwardly over the surfaces of the stem. It will therefore be seen that I provide a very simple and yet effective means for preventing the ringing of watches.

hat I claim as my invention, and desire to secure by Letters Patent, is

The combination, with a watch-case, of a stem thereon provided with recesses adapted to receive the ends of a watclrring E, a ring surrounding the stem and provided with openings through which the end portions of the ring-E pass, and also provided with cavities through which said end portions pass, and projections on said end portions arranged within said cavities, substantially as specified.

HERMAN T. BUCK.
