This invention relatesto a clock casing/of the type in which a'substantially cylindrical movement. is secured'by sliding the movement into the casing througlr an openingin the rear wall thereof. Such casings are commonly made of sheet material such as celluloid, pressed into thedesired shape and having different portions thereof joined: together by cement or otherwiseisecuredto L form a hollow enclosing structure".-

It is the object of my invention to improvethe construction of such a caslng and to render the same less liable to accidental injury.

To the accomplishment of this object, I provide a construction in which a sleeve or tube extends through the casing and is preferably secured to the casing at the front.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings in which Fig. 1 is a front elevation of a clock casing embodying my improvements;

Fig. 2 is a sectional plan view, taken along the line 2-2 in Fig. 1;

Fig. 3 is a perspective view of the movement supporting sleeve;

Fig. 4 is a plan view of a portion of the material from which the sleeve is made; and

Fig. 5 is a partial sectional plan view showing a modification.

Referring to the drawings, I have shown a clock casing of more or less conventional outline and having a front wall 10, a rear wall 11, side walls 12, a top 13 and a base 14. The side walls may conveniently be formed with the front wall and the several parts may be secured together in any convenient manner, such as the application of cement or celluloid solvent thereto.

A dial opening 15 is provided in the front of the casing, said opening being surrounded by a dial ring 16 preferably formed inte- 1924, Serial No. 704,060

gralwitlrthe" front wall 10. The rear wall 11 of the casing isprovided with a similar opening, preferably; surrounded by anin wardly projecting integral flange 17 (Fig; 2). A movement supporting-sleeve 18 is iiisert'ed in the casing from the rear thereof and fits closely within the flange 17. At its front end the sle'eve18may project into-the dial ring: 16' and preferably engages the outer portion thereof, as indicated in Fig. 2.

The-[dial ring 'is secured in position by ce= mentin'gi the same to both the; front and rear walls and the sleeve thus forms a permanent and rigid brace by which the front and rear walls of the casing are held in fixed spaced relation. The sleeve 18 is also of such diameter that the clock movement will be held by friction therein when inserted in the sleeve from the rear of the casing.

The sleeve 18, as'indicated in Figs. 3 and 4, may desirably be formed from a strip of sheet material 20 rolled into cylindrical form and having the overlapping ends 21 firmly cemented together to form a longitudinal or axially extended joint. With this construction, the sleeve 18 may be formed of the same kind or color of sheet material which is used in the construction of the clock casing, a feature which is of great importance in the manufacture of clock casings from colored or fancy material.

A long clock movement frequently necessitates the extension of the sleeve 18 behind the rear wall 11 of the casing as indicated in dotted lines in Fig. 2 and under these conditions it is particularly desirable that the color or design of the sleeve 18 harmonize with the remaining parts of the casing.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is l. A celluloid clock casing having a front and a rear wall, each with a movement opening therein, said rear wall having an integral inwardly projecting flange surrounding the rear movement opening, and a sleeve fitting the rear opening and secured to said integral flange, the front end of said sleeve being also secured to the front wall of said casing and said sleeve supporting and friction ally retaining a clock movement in said casing.

2. A celluloid clock casing comprising a front wall, having an opening and having an integral dial ring surrounding said opening, a rear Wall having a movement opening, and a movement supporting sleeve secured Within said dial ring and to said rear Wall Within .said movement opening and holding said front and rear Walls in fixed spaced relation said sleeve frictionally retaining the movement in said casing. v

8. A celluloid clock casing comprising front and rear Walls having aligned open-e ings, said rear Wall having an inwardly projecting integral flange surrounding the opening therein, and amovement supporting sleeve inserted Within the rear opening and within said flange and secured thereto, the front end of said sleeve being secured to the front Wall of said casing, and said sleeve being formed of-a single piece of sheet material rolled to cylindrical form and having its overlapping ends secured together to form an axially extended joint and said sleeve frictionally retaining the movement in said casing.

4. A celluloid clock casing comprising a first member constituting the front and side Walls of said casing, said front Wall having a dial opening, and a second member forming the rear Wall of said casing, said second member being forwardly flanged at its outer edges and secured Within the side Wall portion of said first member and also having a forwardly projecting flange in its middle portion surrounding a movement opening, and a movement supporting sleeve secured Within saidlatter flange and projecting forwardly to the front Wall of said casing and secured thereto, said sleeve supporting and frictionally retaining the movement in said casing. e

In testimony whereof I have hereunto affiXed my signature.
