Patented Feb. 11, 1936 UNITED STATES PATENT OFFICE CLOCK CASE Application November 30, 1934, Serial No. 755,295

5 Claims.

This invention relates to improvements in clock cases, and more particularly to the case-band and base construction of the case.

One object of the invention is to provide a 5 clock case capable oi being simply manufactured and assembled at minimum cost.

With the above and other objects in view, this invention includes all improvements over the prior art which are disclosed in this application.

In the accompanying drawing, in which one way of carrying out the invention is shown for illustrative purposes:

Fig. 1 is a perspective view of a case-band and base assembled together in accordance with this invention;

Fig. 2 is a fragmental front elevation of the construction shown in Fig. l;

Fig. 3 is a fragmental sectional view on line 3-3 of Fig. 2;

20 Fig. '4 is a perspective view of the base prior to being assembled; and

Fig. 5 is a perspective view of the case-band prior to being assembled.

In the description and claims, the various parts are identied by specific names for convenience, but they are intended to be as generic in their application as the prior art will permit.

Referring to the drawing, II) is a case-band rolled up to annular form from a strip of sheetmetal, and having the case-back I I secured thereto in a usual manner. In view of the fact that the case-band I is rolled up from a strip of sheet-metal, it has, in its finished form, a split or line of separation I2. On each side of the split I2, the case-band is provided with a plurality of openings in the form of slots I3. The base I4 is shaped up from sheet-metal and has its top-surface I5 thereof shaped curved, as shown, to suitably t the curvature of the caseband III. The portion I5 of the base has struck up therefrom a plurality of tongues I6 which are spaced to correspond to the spacing of the slots I3 in the case-band. Thus, the tongues are adapted to extend up through the slots I3 and be bent down, as shown in Fig. 3, to rmly secure the case-band to the base.

By virtue of this improved mode of construction, a case-band can be formed rapidly and at low cost from a strip of sheet-metal, instead of forming the same from a more costly portion of an integral tube, and also more economically than would be necessary in case the band were to be formed with overlapping portions at the split I2 to form a seam.

This improved construction forms an eiiicient,

readily-assembled construction of minimum cost which, in the finished form, as will be evident when the entire clock case with bezel, dial and movement are assembled therein, will entire1y` conceal the split I2 and give ampie strength to 5 the case-band without the need of joining the split ends of the case-band together other than is accomplished in the riveting action which secures them to the base.

'The invention may be carried out in other specific ways than that herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiment is therefore to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.

I claim:

1. A clock case including: a clock base forming one part; a split case-band forming another part and having a minor portion of its circumference engaged against the base and with the split intermediate the ends of the area of engagement of the case-band and base, the main portion of the circumference of the case-band forming part of the outside surface of the clock case; and means adjacent and at opposite sides of said split securing portions of the case-band on opposite sides of said split, to the base.

2. A clock case including: a clock base forming one part; a split case-band forming another part and having a minor portion of its circumference engaged against the base and with the split intermediate the ends of the area of engagement of the case-band and base, the main portion of the circumference of the case-band forming part of the outside surface of the clock case; and means integral with one of said parts and adjacentand at opposite sides of said split securing portions of the case-band on opposite sides of said split, to the base.

3. A clock case including: a base forming one part; a split case-band forming another part and engaged against the base and with the split intermediate the ends of the area of engagement of the case-band and base; one of said parts being provided with openings on opposite sides of said split; and means struck up from the other of said parts and extending through said openings and securing portions of the case-band on opposite sides of said split, to the base.
