CLOCK-CASE.

SPECIFICATION forming part of Letters Patent No. 758,454, dated April 26, 1904. Application filed February 26, 1904- $eria1 No. 195,408. (No model.) 7

To all whom it may concern.-

Be it known that I, ALMERON M. LANE, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Clock- Cases, of which the following is a specification.

My invention relates to improvements in clock-cases; and the main object of my improvement is efliciency and stability in use.

In the accompanying drawings, Figure 1 is a central vertical section of my clock-case less the back. Fig. 2 is a rear View of the bezelring. Fig. 3 is a side elevation of the same. Fig. 4 is a side elevation of a portion of the band and rim. Fig. 5 is an enlarged rear view of a portion of the clock-case shown in Fig. 1. Fig. 6 is a sectional view of the same on the line m w of Fig. 5 looking toward the left, as indicated by the dart. Fig. 7 is a like view of the same with the prong instead of the band bent to bring the prongs and band into engagement.

The subject-matter of this application is in the nature of an improvement on or an addition to the clock-case and dial of my Patent No. $8 1,575, dated October 15, 1901.

A designates the clock-case body of a cylindrical form; 7, the band that fits closely within the front of the said case-body, the said band having the ornamental rim 8 at its front, with an outwardly-projecting flange 9 at the junctionof the said rim and band. The glass 10 fits within the band 7 with its front face against the inner face of the rim 8. The bezel-ring B has L-shaped slits cut in its base or front flange 11 for forming the prongs 12, that are bent up from the said flange at the said L-shaped slits by bending the said prongs at their base on substantially radial bends. The band? is secured within the clockcase body by making two or more outwardlyprojecting sets 13 from the inside in both the metal of the said band and clock-case body, as shown at the upper part of Fig. 1.

The parts thus far described are the same as in my aforesaid patent. The only change therefrom which I make is to form three or more openings 14 in the band and after the parts are assembled bending in some cases either a portion of the band at the said openings or bending the prongs 12, that come into a position adjacent to the said openings. I prefer to make the length of the openings in the band equal to or a little in excess of the distance from one of the prongs 12 to the next adjacent prong, provided, as herein shown, there is an even number of the said prongs and only three openings in the band. As in my former patent, the front of the glass 10 rests on the inner face of the rim 8, and the base of the bezel-ring rests against the rear face of the glass, with the prongs 12, or the major part of them, bearing firmly against the inner face of the band. The length of the prongs and the position of the outer or rear wall of the openings 14 in the band are made relatively to each other and the thickness of the glass, that when all the parts are properly inserted in the case-body the rear ends of the said prongs will be substantially in the same plane as the adjacent Wall of the openings 14. With three openingsin the band and with sixteen prongs, as shown, there will be one prong opposite two of the said openings, as shown in Figs. 5 and 6, and two prongs adjacent to the third opening, so that no matter how the bezel-ring may be turned before insertion there will always be at least one prong opposite each of the openings in the band when inserted. The holes or openings in the band are punched from the outer side after the band is formed and the tendency of the punch is to force the metal slightly inward at the rear of the said openings. The prongs are also formed so as to project slightly outward. In most cases the prongs will snap into engagement with the rear Wall of the openings upon crowding the bezel-ring into place. If desired, however, a suitable tool, something with a thin edge, may be inserted between the edge of the band in the rear of the opening to bend that portion of the band inwardly and bring it into engagement with the rear end of the prong, as shown in Figs. 5 and 6, whereby the bezel-ring is'positively locked within the band against being pushed out by pressure on the outer face of the glass. The clock-case body by surrounding and inclosin g the said band covers up the openings 14, so that they do not show on the outside of the clock-case.

Instead of bending the metal of the band the said band may be left in its cylindrical form throughout and the prongs adjacent to the openings 14 bent to carry their ends into engagement With the Wall of the opening, as shown in Fig. 7. Inasmuch as the parts in Fig. 7 are identically the same as those in Fig. 6, with the single exception that a different part is bent for engaging the band and prongs, I have used the same reference-numerals in both of the said figures.

In case a glass is thicker either in Whole or in part than the thickness to which the prongs have been set the effective length of the prongs may be shortened accordingly by bending them flatwise, after which they may be engaged With the band as hereinbefore described.

1 claim as my invention- In a clock-case, the com bination of the clockcase body With a band and rim secured in the front thereof, the said band having openings 14, the glass, and the bezel-ring having the series of prongs projecting rearwardly from its base or flange, some of the said prongs being in engagement With the metal at the rear Wall of the said openings.
