CLOCK-CASE.

SPECIFICATION forming part of Letters Patent No. 242,246, dated May 31, 1881.

Application filed February 23, 1881. (ModeL) To all whom it may concern Be it known that we, WILLIAM H. ATKIN- SON and DANIEL M. SoMERs, both of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Clock-Cases, of which the following is a specification.

The object of our invention is to provide a clock-case of very attractive appearance, which may be cheaply manufactured by the various processes common in forming articles of sheet metal.

The invention consists in a head for aclockcase composed of a polygonal disk having radial notches at regularintervals in its perimeter, and having the marginal portions between the notches folded inward toward the center to form a doubled flange, and bent at an angle to said flange to form a polygonal rim.

It also consists in the novel construction of the front head of the case, and a novel method of combining it with the dialplate and an inner bezel-ring, whereby provision is made for attaching the movement to the dial and for holding the dial and front glass in place; and it further consists in a novel construction of a handle and means of attaching the same to the case.

In the accompanying drawings, Figure 1 represents a portion of a sheet-metal blank, from which the head may be formed. Fig. 2 represents a portion of the head after being folded or doubled. Fig. 3 represents a section of the portion of the head shown in Fig. 2. Fig. t represents a vertical section through a clock-case embodying our invention, taken on a plane parallel with the heads. Fig. 5 represents a vertical section on the dotted line a: 00, Fig. 4 5 and Fig. 6 represents a modified form of handle.

Similar letters of reference designate corresponding parts in all the figures.

Our clock-case is composed, mainly, of three parts-namely, a band, A, here shown as of polygonal shape, and formed of a strip of sheet metal the two ends of which are lap-joined at a, a back head, B, and a front head, C, both also composed of sheet metal, as hereinafter described.

To form the back head, 13, we take a disk, the form of half of which is indicated in Fig. 1, and in the angles thereof we cut notches b. \Ve then double or fold the marginal portions between the notches b, on the dotted line 0, over upon the disk itself, and thus form a doubled flange, d, (see Fig. 2,) larger than the size of the band or body A. We then bend each marginal portion at a right angle, or thereabout, to the flange, and thus form a projecting polygonal rim, 0, of a size to conveniently fit within the band A. The sides of the notches I) should be cut at such an angle that when folded, as above described, the edges of the portions of the flange will meet, as also will the edges of the portions of the rim 0, thus forming a continuous flange and rim. The back of the head B is spun or drawn outward, as shown, and is depressed or sunken, as shown, so that when the keys or windinghandles are turned down they will be concealed or lie within such depression.

The fronthead, C, is notched, doubled,orfolded, and bent in substantially the same wayas the back head, so as to form a doubled flange, cl, and inwardly-projecting rim 0, and both of the rims 0 may be so nicely fitted as to be held in the band A by friction; or the rim of the front head may be tacked to the band with solder, if necessary. After the front head, C, has formed upon it the flange (1 and rim 0 the portion within the flange is spun or deflected outward, so as to project in the opposite direction to the rim 6 and form a cylindrie rim, f, the edge of which is turned over and inward atf.

D designates the dial-plate, which is secured to the front C by screw-bolts g or other suitable means, and E designates the glass, which fits bet-ween the turned-over edge 1" of the rim f and an inner bezel-ring, 7b, of the form shown in Fig. 5, which fits loosely upon the dial-plate D and within the circular rim f of the front head, C.

F F designate the front and back plates of the movement, connected by posts F and the whole movement is held in place in the case by means of knee or angle pieces 17, which may be formed in one piece with the plate F, as shown in Fig. 5, or which may be separate pieces riveted to the plate, as shown in dotted outline, and which, in either case, are secured to the dial-plate D by the screw-bolts g, which secure the dial-plate, or other means.

G designates a handle, provided with lips or prongs 7:, which are inserted through holes I in the band A, and then bent over to securely hold the handle in place. We make no claim to this form of handle.

In lieu of the handle shown in Fig. 4, we employ a handle like that shown in Fig. 6, consisting of two lugs or eyes, each provided with a lip or prong, k, inserted through holes Z in the case and bent over a bar, m, and pairs of jointed toggle-links a n, by which the two ends of the bar are connected with the two lugs or eyes. When the case is not supported by the handle said handle will assume the position shown in dotted outline.

If desirable, the sides or faces of the band A might be paneled either with concave panels A, as seen in Fig. 4, or with convex panels, and the whole case may be plated or finished in any desired manner to suit the taste.

hat we claim as our invention, and desire to secure by Letters Patent, is-

l. A head for a clock-case, composed of a polygonal disk having radial notches at r egular intervals in its perimeter, and having the marginal portions between the notches folded inward toward the center to form a doubled flange, and bent-at an angle to said flange to form a polygonal rim, substantially as specified.

2. The combination, with a head for a clockcase, composed ot a disk of sheet metal having its marginal portions doubled or folded inward to form a doubled flange and bent at an angle to said flange to form a rim, of a dialplate secured to said head, and a front plate for a movement, secured to the said flange by angle or knee pieces, substantially as specified.

3. The combination of the front head, 0, comprising the flange d, the inner rim, 0, and the outer rim, f, with its turned-over edge f, the dial-plate D, the inner bezel-ring, l1, and the glass E, substantially as specified.

4:. The combination, with a clock-case, of the handle composed of the bar at and the togglelinksn n, adapted to fold inward toward each other, and thereby draw said bar inward toward the case, substantially as specified.
