I D. M. CLARK WATCH SHOCK ABSORBER Filed April 4,,' 1924 Patented Apr. 27, 1926.

UNITED STATEfi DANIEL M, CLARK, OF JAMEsBUItG, NEW JERSEY.

.VTATGH SHOCK ABSORBER.

Application filed April 4, 1924. Serial No. 704,245.

To aZZ whom it may concern:

Be it known that I, DANIEL l I. CLARK, citizen of the United States, resicingat .lamesburg, in the county of Middlesex and f :ate of New Jersey, have invented certain new and useful Improvements i atch Shock Absorbers, of which the following is specification.

This invention relates to watch shock absorbers, and has for its object the cushioning of the works of a watch against injurious impacts, for example should the watch be accidentally dropped upon a hard surface, no matter how the watch falls whether so as to strike any portion of the periphery or any point of either face, front or back. The stated object is attained in this invention by supporting the works within the case by a plurality of coil springs, so that the movement of the works of the watch as a whole whatsoever may be the direction is efiectively taken up by the springs without harmful result.

In the accompanying drawings the form and arrangement of the parts of this invention are illustrated, and Fi 1 is a front view of a watch case, slightly enlarged, showing this invention applied thereto. Fig. 2 is an enlarged partial section on broken line 22 of Fig. 1, showing a modification. Fig. 3 is a like partial sectional view setting forth another modification. Fig. 4 is a cross-section of the parts as delineated in Fig. 1, and Fig. 5 is a like crosssection in which appears a modified form of the outer and inner rings.

Throughout the description and drawings the same letter is used to refer to the same part.

Considering the drawings, the case A has the rim (4, and arranged usually against the rim within the case is the outer ring B of this invention, of which the inner ring is marked 6 and the spaced coil springs C. The winding stem of the watch is referred to by letter D, and it will be noted that the inner ring Z) may have an opening cl so that the ring may move slightly with respect to the stem without contact.

As best shown in Fig. 4 the inner ring has an annular shoulder E to receive and seat the works of the watch.

The modification illustrated in Fig. 5 so far as the springs G and inner ring 9 are concerned is the same as before but the outer ring F has the external threaded portion for engagement with the correspondingly threaded edge portion of a case when such construction is adopted.

In the modification shown in Fig. 2, the case has the peripheral, hollow rounded form'H, and the outer ring is made with an extension j to lit within the hollow II of the case. To secure the parts J and the case together, the screw K is introduced as illustrated, the adjacent portions of the parts being fashioned accordingly, but it will be understood that this invention is not 0011- fined to any means or method of securing the outer ring and case together. If it is necessary the outer ring may be interrupted by a transverse cut is, in order that it may be slightly compressed to enable it to be en gaged with the curved hollow peripheral part II of the case. I11 Fig. 2 the inner ring is marked L, and the coil springs are designated by the letter Z. These are the same as before. Usually, the ends of the springs are soldered to the outer and inner rings in proper position, but this invention is not intended to be limited to any particular means or method of securing the ends of the springs to the rings. Further considering Fig. 2, let it be assumed that M marks the top plate and N the bottom plate of the works of a watch. The plate M may be fastened to the inner ring L by means of a screw m engaging a threaded orifice in the inwardly turned ec ge lug m of the ring L. It will be understood were such construction followed, the lower plate N of the works would be formed with suitable edge recesse n for the passage of the lug m when the works are introduced into the inner ring L.

In the. modification set forth in 3 the case 0 has the same curving, hollow peripheral portion as described in connection with Fig. 2. The outer ring P and the fastening screw Q with its necessary adjuncts are the same as before, as are also the springs R. But, for the inner ring posts S are substituted extending between the plates T and U of the works of the watch, and secured in place by soldering or in any other manner used by jewelers.

The operation is the same in the modifications, as in the preferred form of this invention, and is believed to be now clear from the drawings and the foregoing. lhe coil springs cushion the works from shocks no matter how the watch may strike as it falls, or however a blow is received by the case.

As the devices for supporting the inner and outer ends of the spaced coil springs Within the Watch case may obviously be so readily modified by almost any Watchmaker, it is not the intention of this application to limit the invention to the holding contriva-nces illustrated.

Having now described this invention and explained the mode of its operation, I cleimz- 1. In a Watch shock absorber, the combination with a case, of an outer ring Within the ease, detachable means for securing th said ring and the case together, a support for the Works of a Watch inside the said outer ring a plurality of coil springs spaced apart, one end of each spring being connected with the said ring, and means for connecting the other ends of the said springs with the said Works support.

2. In a Watch shock absorber, the coin bination with a case, of an outer ring within the case, detachable means for securing the said ring and case together, a plurality of coil springs spaced apart, one end out each spring being connected with the said ring, an inner ring constructed to receive the Works of a Watch, and the inner ends of the said springs being connected with the said inner ring.

In testimony whereof? I afiix my signature.

DANIEL M. on-inn.
