UNITED STATES PATENT OFFICEVo ROBERT J. QUIGLEY, OF TORONTO, ONTARIO, CANADA.

WATC H-CAS.

SPECPCA'IIN forming part of Letters Patent No. 384,640, dated June 19, 1888.

Application filed February 9, 1883. Serial No. $263,472.

To all whom it may concernf Beit known that l, ROBERT JOHN QUIGLEY, ofthe city of Toronto, in the county of York, in the Province ol" Ontario, Canada, manufacturer oi' watclivcascs, have invented a certain new and useful Improvement iu VatelrOases, of which the following is a specification.

The object of the invention is to produce acheaply made, easily iinished, and strong watchAcase in which the movement-ring may be readily adjusted to suit watch-movements of various makers, and it consists, essentially, in making the watch-case center wider than the movement ring and cutting a thread through the center, the said center being sufficientl y wide to receive a screwed movementring and screwed projections formed on the back and bezel, sufficient space being left between thc movement-ring and the projections to permit the said movement-ring to be adjusted toward either side of the center to suit the particular watclrmovement to be inclosed.

Figure l is an enlarged sectional view of my improved watch-case and its adjustable movement-ring. Fig. 2 is a side elevation of the back. Fig. 3 is a side elevation of the bezel. Fig. 4. is a sectional detail of the center. Fig. 5 is a detail, partly in section, of the movement-ring. Fig. 6 is a detail, partly in section, of a double or divided movement-ring.

A is the center, made wider than the movement-ring B, which is screwed into it, as indicated. The thread in the center A exten'ds from edge to edge, and the center A is wider than the movement-ring B.

Screwed projections c, formed on both the back C and bezel D, are designed to screw into the centerA, the center being sufciently wide to receive the screwed projections and leave (No model.)

room on either side of the movementring to permit of its adjustment to suit the watchmovement it is intended to contain. At the base of each of the screwed projections a, I form a ring, b, designed to butt against the edge ofthe center when the screwed projection a on the back or bezel is screwed into the center. This ring on the back or bezel also strengthens the case around thejoint.

By screwing the movement-ring inside of the center and making the latter sufficiently wide to permit the adjustment of the former, I am able to use a double or divided movement-ring, as shown in Fig. 6, so that the said movement-ring may be more readily adjusted to suit watch-movements of various makers.

Vhat I claim as my invention is- 1. In a watchcase, the combination of the following elements: a center of greater width than the movement-ring and threaded on its interior circumference,amovement-ringscrewthreaded on its periphery and screwed into the center, and the back and bezel engaging the center and permitting adjustment of the movement-ring, substantially as and for the purpose specified.

2. A watch-case having a thread cut in the interior circumference of its center which is made suiciently wide t0 receive the movement-ring, and screwed projections c, formed on the back O and bezel D, in combination with divided or double movement-ring B, substantially as and for the purpose specified.
