CLOCK GAS ING Filed July 31, 1940 I 20] L. CAR/330w Patented Nov. 4, 1941 CLOCK CASING Elof L. Carlson, Bristol, Conn, assignor to The E. Ingraham Company, Bristol, Conn., a corporation of Connecticut Application July 31, 1940, Serial No. 348,607

3 Claims.

The present invention relates to clocks and more particularly to a clock of the type wherein the clock casing and base are manufactured as separable pieces and thereafter secured together.

Heretofore, in the manufacture of clocks of the aforementioned type, it has been necessary to provide multiple securing means for rigidly securing the casing to the base in a manner which would prevent any turning or relative movement of the casing to the base. An object of the present invention is to provide a multiple piece clock of the above-indicated type wherein the casing and the base are so constructed that they substantially interlock with one another and may be rigidly held in position by a single securing means.

A still further object is a clock of the aboveindicated type wherein the parts may be inexpensively manufactured, such as by stamping them from suitable metal, and thereafter easily and quickly assembled.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawing:

Figure 1 shows a base for an alarm clock made in accordance with the present invention, supporting a clock casing and dial support;

Fig. 2 is a profile view of the clock casing assembly illustrated in Fig. 1;

Fig. 3 is a cross sectional view taken through line 3-3 of Fig. 2;

Fig. 4 is a cross sectional view taken through line 4-4 of Fig. 1;

Fig. 5 is a plan view of the clock base illustrated in Fig. 1; and

Fig. 6 is a cross sectional view taken through lines 6-6 of Fig. 5.

Referring to the drawing, the invention comprises generally a clock having a casing ID, a bezel ring I2, and a base M to which the casing is secured by a single securing means l6. More specifically, the casing shown is of cylindrical contour and the bezel I2 is of usual construction having a face flange [3, a rounded or beaded edge I5, and a rearwardly extending skirt ll insertable within the casing for frictionally holding the bezel in position. When so positioned, the beaded edge IS in effect provides a bead around the forward peripheral edge of the casing of slightly greater diameter than the casing proper.

To support the casing, the base l4 comprises a dome-like metal member shown as being of substantially triangular shape and stamped to provide a flat peripheral supporting edge 20, a peripheral wall 22, and a countersunk top rest 24. The peripheral edge 20 provides a firm mounting surface for the base on a'flat surface upon which the clock would normally be rested, and the peripheral wall 22 serves to space the top rest 24 above the surface.

To position the clock casing and bezel onto the base, the top rest 24 is shaped to cooperatively interlock with the casing and bezel ring, whereby when the parts are secured in assembled position the casing and bezel ring will be securely held against any movement relative to the base. To accomplish this, the countersunk top rest 24 includes a central depression 26 of transverse curvature corresponding to the curvature of the casing in and a length corresponding to the width or depth of the clock casing and terminating at its rear edge in a back wall 30 perpendicular to depression 26. Forwardly of and contiguous with depression 26 is a second depression 28 having a transverse curvature corresponding to that of the bezel ring l2 and a longitudinal curvature cor responding to the face flange I3 and bead l5 of the bezel ring.

With this construction, when the casing is positioned on the base, a portion of the casing ID will be seated within the central depression 26 and a portion of the bezel ring within the depression 28. Due to the fact that the longitudinal curvature of the depressions 26 and 28 correspond to the longitudinal curvature of the casing and bezel ring, the rear wall 30 of the depression 26 will abut against the rear wall of the casing and the forward wall 32 of the depression 28 will abut against the face of the bezel ring l2, thus restraining the casing against longitudinal movement relative to the base. Moreover, as a portion of the casing is in effect countersunk into the base, rotation about a vertical axis is prevented.

Because of the foregoing, it is possible to utilize the single securing means 16 comprising a bolt 34 extending through an opening in the central depressed portion 26 of the base and threadably engaging a ferrule 36 secured in the clock casing. A firm support may further be assured by providing a circular depression 38 in the depression 26 underlying the casing ferrule 36, and thus upon taking up of the bolt 34 a positive resilient tension will be obtained.

Although the casing l2 has been shown as being circular, it is apparent that with any type casing wherein the lower portion has a given continuous curvature a like result can be obtained by providing a countersunk top rest within the base of a like curvature. Another advantage is that in stamping out the base, the central portion 24 may be sloped downwardly from the front of the base, thus arranging the clock casing at an angle, permittirx a more ready reading of the dial.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of he invention which, as a matter of language, might be said to fall therebetween.

I claim as my invention:

1.In combinati n, a clocl: casing having a lower portion of continuous curvature, a bezel ring secured in said casing and having a lower portion of like curvature to the clock casing, but of slightly greater diameter than said clock casing, a base for supporting said casing and bezel ring, said base having a top rest countersunk to provide a main depression corresponding to the curvature of the clock casing and a second d pression forwardly of said main depression and contiguous therewith and corresponding to the curvature of said bezel ring, and means for securing said casing and bezel ring into said top rest.

2. In combination, a clock casing having a lower portion of continuous curvature, a bezel ring secured in casing, said bezel ring having a face flange and a lower portion of like curvature to said clock casing, but extending slightly beyond the casing, a base for supporting said casing and bezel ring and comprising a top rest countersunk to provide depressions into which the curved portion of said clock casing and bezel ring extend, said depressions including a front wall abutting the face flange of the bezel ring and a rear wall abutting the rear wall of said clock casing, and means for securing said casing in said depression.

3. In combination, a cylindrical clock casing, a bezel ring secured in said casin' and having a face flange of sli htly greater outside diameter than the casing, and a base comprising a top rest and a peripheral wall depending therefrom, said top rest being count-esunk to provide a curvature corresponding to the curvature of the casing and the bezel ring and in which said casing and bezel ing rest, and means for securing said casing in said base and comprising a bolt extending through aligned openings in said casing and top rest.
