'and more particularly -to means for securing the works of small clocks within supportin frames.

In t e manufacture of small clocks having sup orting frames it is usual to provide means or secu-ring the works within a casing separate from the pillars which unite the plates between which the movement is mounted, and t'o also provide fastening means for securing the casing to the supporting frame. It is also usual to provide anges for over-lying the outer surfaces of the supporting frames separate from but secured to the 'casings which inclose the Yao works.

The primary object of my invention is to provide a clock and supporting frame therefor which will require but a single set of fastening devices for connecting the plates of the movement, for securing the works within the casing, and for attaching the casing to the supporting frame.

A lfurther object of my invention is L provide a casing for clocks having formed integrally therewith a iiange for engaging the front surface of a supporting frame.

A still fur-ther object of my invention is to provide a clock and a supporting frame therefor which will be simple in construc-l tion, inexpensive in manufacture, and efficient 1n use.

My invention as herein dlsclosed may be generally described as comprising works having plates between which the movement is supported, an inclosing casing having an integral flange overlyin the front surface of the frame, a supporting frame, a removable back for the supporting frame, rods uniting the' plates of the works and extending through holes inthe casin and back plate of the frame, and series o nuts on the rods engaging the back plate of the works, the outer surface of the casing, and

'the `outer surface of the back plate of the frame.

My invention will be more fully described hereinafter' with reference to the accomanying drawings in which the same is illustrated as embodied in two convenient and practical'forms, and in which Figure 1 is a front elevational View; Fig. 2 a. rear elevational view Fig. 3 a cross'- sectional view on line 3--3 Figll; Fig. 4- a perspective view of the casing;` Fig. 5 a perspective view of the back plate of the frame; Fig. 6 a front elevational view of a 'modified form of my invention; Fig.l 7 a rear elevational view of the modification shown in Fig. 6; Fig. 8 a vertical view on line, 8-8 Fig. 6; and Fig.` 9 a perspective view of the back plate of the supporting frame.

. Similar reference characters are used to designate similar parts in the several gures ofthe drawings.

Referring more particularly to Figs. 1 to 5 inclusive, reference letter A designates a supporting frame for a clock which may be made of any suitable material and of any desired design.

surface. J

B designates a casing for inclosing the works, such casing being formed integrally and comprising a circular back wall and cylindrical side wall. An outwardly projecting flange Z) surrounds the open end of D indicates the beveled crystal which is vsecured within the open end of thecasing plate C2 by means of studs 0.

a indicate the feet of the supporting frame adapted to rest upon a supporting B by means of a bezel E having a cylindrical an e. fitting within the casing and an inward y projecting fiang'e e overlying the periphery of the crystal.

F designates a reflector whichl is interposed between the crystal and the'dial so as to symmetrically space thel crystal and! dial apart.

G- G2, and G3 designate rods interposed between the plates C and C2 for supporting the same in parallel relation Each of these rods is of a greater diameter between the plates than the portions which extend through the plates, thereby forming shoulders against which the inner surfaces of the lplates engage. The reduced ends of the rods which extend through the plate C2 constitute the posts c for supporting the dial. The reduced portions of the rods which project through the plate C are screw-threaded to vagainst the nutsvg thereby supporting the works within the casing,

The screw-threaded portions of the rods G, G, and G3 also extend through holes in aback plate H of the supporting frame and are provided with nuts g3 engaging the outer surface of such plate. The back plate H is preferably concave and is provided with an outwardly projecting flange /L which overlies the rear surface of the supporting frame.A

The nuts g3 consequently through their engagement with the rods draw the flange b on the casing against the front surface of the frame and simultaneously draw the flange /L on the back'plate against'the rear surface of the frame, thereby tightly securing the casing within the frame.

In Figs. (5 to S inclusive I have illustrated my invention as applied to a clock having a modilied form-of supporting frame. In this modification reference character A designates a supporting frame in the form of a plate having feet c', am for supporting the bottom thereof. The casing with the -Works therein extends through an opening in the frame A so that the flange b around thev casing will overlie the front surface of theframe. H indicates the back plate of the frame which is in the form of a cylinder having a circular back Wall and cylindrical Y side walls and provided with an outwardly projecting fla-nge -L around its open end which overlies the-rear surface of the frame A. The screw-threaded portions of the rods G', G, and G3 extend through holes in the rear wall of the supporting plate H so that the nuts g3 serve to force the flange h tight-ly against the inner surface of the frame and simultaneously draw the flange b on the casing tightly aga-inst the outer` surface of the frame. a2 indicates a leg for supporting the frame at the rear'thereof, such leg being secured to the frame by means of a hole in' the upper end thereof through which the screw-threaded end of the rod G projects, a nut g4 being provided on such rod for clamping the upper end of t-he leg against the nut g3 on such rod.

From the' foregoing description it Will be observed that I have invented an improved clock and supporting frame therefor, in which thesa me fastening devices secure the plates which support the Works together, support the Works within the casing, and secure the casing to the supporting frame. It is evident'that by my improvement the Works may be readily secured Within the casing and the casing easily secured to the supporting frame. It will also be observed that my improved casing is provided With an integral flange for overlying the front surface of the frame, thereby avoiding the necessity of'providing a front flange separate from the casingc While I have described more or less precisely the details of construction, I do not` wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the-substitution of equivalents, as circumstances .may suggest or render expedient Without departing from the spirit of my invention.

Having now fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a clock, ,an inclosing casing having a shoulder thereon; a frame bearing on one side against said shoulder; abackplate bearing against the opposite side of the frame to hold it against said shoulder; bolts passing through said back-plate and projecting through the rear of the casing, nuts on said bot for tying the bolts the back-plate and the casing together and clamping the frame between the shoulder on the casing and the back-plate; and clockwork arranged within the casing and supported wholly upon the free ends of the bolts.

2. In a clock, an inclosing casing having an outwardly projecting shoulder near the front end thereof; a frame surrounding the casing and engaging with said shoulder` on the rear sidethereof; a back-plate having a shoulder arranged in rear of'and engaging with said frame; bolts passing through said back-plate and the rear wall of the casing and projecting into the interior of the casing; a plurality of nuts on said bolts for tying the back-plate and the casing rigidly together and at the same time clamping the frame between the shoulder on'the casing and the shoulder on the back-plate; and supporting plates for a clock-work arranged within sald casing and supported Wholly upon the free'ends of said bolts.

3. In a clock, an inclosing casing having an exterior shoulder near the front thereof; a frame surrounding the casing and bearing against the shoulder on the rear side there-Y of, a back-plate provided with a shoulder engaging With the rear face of the traine; a bolt passing through said bank-plate and the rear Wall of the casing and projecting into the interior of the casing; nuts on said bolt for tying the rear Wall of the easing, the back-plate and the bolt together and at the same time clamping the frame between the shoulder on the casing and the shoulderv on the back-plate; supporting plates for a clock-Work arranged Within said casing and supported wholly upon the free end of the bolt; and a dial supported by saida bolt near the front end of the casing.

,4. A clock casing comprising an outer casing -or frame, an inner 4 easing having means to prevent the passage of the inner easing through the outer easing, a back plate, bolts or posts for carrying the clock- Works passing through the back of the inner easing and the back plate, the said bolts having shoulders resting against the back of said inner easing and meanscarred by the posts for drawing together and holding the inner and outer caslngs and the back plate.

In testimony whereof, I sign this specification in the presence of two Witnesses.
