CONNECTICUT, A CPRPORATION NICKEL CLOCK i Application filed November` 2, 1928. Serial No. 316,639.

facture aclock of the character described,

distinguished' by fewness of parts, relative thinness from front to rear, refinement and elegance of design and workmanship, and the comparative inaccessibility of dirt and dust' 'to its mechanism.

With these ends in view our invention consists in a nickel clock having certain details of construction and combinations ofparts as will be hereinafter described.

In the accompanying drawings:

Fig. 1 is a view in rear elevation of a clock embodying our invention;

Fig. 2 is an edge view thereof;

Fig. 3 is a view thereof in vertical central section;

Fig. 4 is a detached bottom view of the movement as removed from the case;

FiO. 5 isa detached edge View of the distorte or D bell as mounted in its V bracket;

Fig. 6 is a plan View thereof; and

Fig. 7 is a detail sectional view showing the manner of fastening the movement to the integral back of the case.

' In carrying out our invention as herein shown, we employ a struck-up sheet-metal cup-like case 10 open at its forward edge and having a solid or integral back 11', whereas such clocks, as ordinarily made, are provided with independent flanged back-plates fastened in place in a varlety of ways by their flanges. By forming the back of the clockcase integral with it, simplicity and cheapness of construction is secured as well as a high degree of protection to the movement enclosed within the case against the access of dirt and dust thereto; The time-movement, to which we have applied the general designating-numeral 12, may be of any ap roved construction and is secured in place y the extension of the threaded rear ends of its pillars 13 through perforations 14 in the back 11 'of the case and the application of nuts 15 to their threaded projecting ends.

Into the open forward end of the case we insert the relatively-wide annular assembling-flange 16 of a one-piece sheet-metal bezel struck up at the forward edge of the said fiange to form a stop-shoulder-17 larger in diameter than the said flange land abutting against the forward edge of the case 10 to position the bezel with respect to the case and form a good joint at this point. The said stop-shoulder 17 e is interposed, as it were, between the flange 16 and an inwardly-turned crystal-retaining flange 18 and forms an annular crystal-receivin groove 19 receiving the edge of a non-brea able crystal 20 larger in diameter than the said groove and bowed so as to clear the hour and minute hands 21 and 22 of the time-movement 12.

Between the dial 23 and the integral back 11 of the case we locate a distorted or D- shaped clock-bell 2/1 which is suspended with its open edge uppermost from the time-movement by a bowed two-armed V-shaped bracket 25 to which it is secured by a single screw 26, the diverging ends of the arms of the said bracket being formed with perforations 27 for receiving the two lower pillars 13 of the time-movement, whereby the bracket is held in place, as shown in Fig. 1.

In order to reduce the thickness of the clock from front to rear tothe minimum, the bell 24 has its rear portion flattened as at 28, whereby it is distorted, as it were, and given a D-shaped form, not curtailing its tone but reducing the space necessary to it location out of the way within the clock-case.

Adjacent to the flattened rear portion 28 of the bell the integral back 11 of the case is provided with sound holes 29,- as also shown in Fig. 1.

For supporting the clock it is provided with a one-piece strap-like base formed of a flat strip of relatively-heavy sheet-metal preferably corresponding substantiall width to the width of the case 10 from front to rear and shaped to form a depending central portion or cradle 30 conforming in curvature to the curvature of the case which sets into it. The respective ends of the said base are downwardly bowed to form feet 31 which, on account of their long line bearing upon the shelf or tablegupon which the clock is placed, provide a very stable suplport therefor. The said base is secured to t e said case 10 by a screw 32 passing upward through the center of its cradle-portion and also upward through the bottom of the case 10, ne-

cessitating therefore but a sin le fastening means for securing the base to t e case. The dial 23 before mentioned is secured by brackets 33 to the front plate of the two movement- plates 34 and 35.

Our improved clock as thus constructed is simple, easy to assemble and disassemble, comparatively thin from front to rear and admirably adapted for the exclusion of dust and foreign matter into its interior.

We claim:

In an alarm clock, the combination with a cup-shaped case open in front and having an integral back, of .a time-movement installed in the said case through the open front thereof, a removable bezel mounted in the open front of the case, a cr stal carried by the said bezel, a cup-shaped liell attened on one side, and a bracket carried by the timeg5 movement and arranged exterior to the bell, with the flattened side thereof adjacent to it and extending around under it for the attachment of the bell to it, whereby the bell is located outside of the bracket and the thickness of the clock-unit from front to rear is reduced to the minimum.

In testimony whereof,we have signed this specification.
