EDWARD F. HEFFERNAN, OF TORONTO, ONTARIO, CANADA.

WATCH -C ASE.

SPECIFICATION forming part of Letters Patent No. 373,364, dated November 15, 1887.

Application filed February 8, 1887. Serial No. 226,970.

To all whom it may concern:

Be it known that I, EDWARD FRANCIS Hun- FERNAN, of the city of Toronto, in the county of York, in the Province of Ontario, Canada,

watch-case maker, have invented certain new and useful Improvements in Watch-Cases, of

which the following is aspecification.

The object of the invention is to apply a dialring to the bezel of a watch-case in such a manner that the same case may be used for movements of various thicknesses and yet have a dial-ring always in contact with the dial; and it consists, essentially, in formingin the bezel an annular wall extending from the glass-groove to a point near the snap and surrounding an opening slightly larger than the diameter of the dial-plate, the dial-ring being fitted to the annular wall in such a manner that it will readily adjust itself to suit any variation in the thickness of the movement contained within the case, substantially as hereinafter more particularly explained.

Figurel is an enlarged sectional view of a dummy watch-case containing my improvement. Fig. 2 is a top view of the bezel.

or represents an annular well formed within the bezel A, and extending from the glassgroove b to apointnear the snap. At the bottom ofthc wall a,lpreferably form an inwardly-proo jecting flange, d, which surrounds an opening slightly larger than the diameter of the dialplate B. A dial-ring, C, is inserted into the bezel A, and fits theannular wall a, so that it may be readily adjusted and yet beheld at any desired point on the saidwalhthe flange d preventing it falling through the bezel. As the opening around which the flange d extends is slightly larger than the diameter of the dial-plate B,the said dial-plate may extend into the bezel so as to come in contact with the dial-ring C, which (No model.)

It is of course not absolutely necessary that the dial-ring 0 should rest upon the dial-plate B; but when it does it forms adust-ring, and in fact even when it does not fit against the dialplateit prevents any dust which may find its way through the glass-groove b from getting into the movement.

By the adoption of my invention a manufacturer of Watch-cases will be able to produce cases which may be applied to movements of various thicknesses, and which may have printed on its dial-ring figures necessary fora calendar or for a twenty-four-hour dial.

\Vhat I claim as my invention is- 1. A bezel having an annular wall extending from the glass-groove to a point near the snap and surrounding an opening slightly larger than the diameter of the dial-plate, in combination with a ring adj ustably fitted to the annular walland having an opening sufficiently large to expose the face of the dial-plate, substantially as and for the purpose specified.

2. A bezel having an annular wall extending from the glass-groove to a point near the snap, where an internally-projecting flange is formed which surrounds an openingslightly larger than the diameter of the dial-plate, in combination with a ring adjustably fitted to the annular wall and having an opening sufficiently large to expose the face of the dial-plate, substantially as and for the purpose specified.
