Filed June 20, 1930 Fatented Mai. 7, 1933 UNITED STATES PATENT "OFFICE EDWARD HOWARD, OF ELGIN, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO ELGIN NATIONAL WATCH COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION ILLINOIS WATCH Application filed June 20,

This invention relates to watches, and particularly to means whereby the movement may be accurately located within the case and held against rotation from its desired position.

The invention will readily be understood from the following description taken in con junction with the accompanying drawing, in which- Figure 1 is a plan view of a watch, partly broken away to disclose internal structure;

Figs. 2, 3 and 4 illustrate successive stages in the production of a movement ring;

Fig. 5 is a sectional view showing the movement ring in place in a watch case member; I

Fig. 6 is a similar view showing a modi fication;

Fig. 7 is a perspectiove detail with parts broken away to show parts which would otherwise be concealed; and

Fig. 8 is a sectional view of a watch, the bezel being removed and the movement shown in elevation.

Referring to the drawing, the numeral 10 designates a watch embodying the invention. The watch is shown by way of example as a wrist watch, but it is to be understood that the invention may be applied to any other type of watch. The watch may comprise a case member or back 11, a movement ring 12 mounted therein in any suitable way, for example by soldering, and a front case member or bezel 13, secured in any suitable way to the back 11 or the movement.

The movement 14 comprises a top plate or pillar plate 15 upon which the dial 16 is superimposed. The movement may be secured in the movement ring in any suitable known manner. The stem 17 extends through aligned slots 18 and 19 in the back 1930. Serial No. 462,505.

the recess so that the entrance of dust is prevented. Where the top plate 15 is of sufiicient thickness, the tongue 21 may lie in the plane of the movement ring, as shown in Figs. 5 and 7. When the top plate 15 is relatively thin, it is convenient to bend the tongue 21 upwardly, as shown in Figs. 6 and 8.

The formation of the movement ring is shown: in Figs. 2, 3 and 4. It may suitably be formed from a blank such as shown in Fig. This blank is formed into desired cup-shape by suitable die pressing operation, the result being shown in Fig. 3. The opening is then pressed in the face of the movement ring leaving the tongue 21 as shown in Fig 4:. The surface of the movement ring is finished by planing or other operation, and the ring is then soldered into the back as shown in Fig. 5. When necessary, the tongue 21 is turned upwardly as shown in Fig. 6.

The recess 20 in the pillar late may also serve for aligning the pillar p ate during the manufacture and assembly of the movement. The engagement between the tongue 21 and the recess 20 secures the movement against rotation so that there is no tendenc for the stem 17 to be moved into contact witii the walls of the slots through which it passes.

It will be readil understood that various modifications can be made within the scope of the invention. For example, the tongue and recess engagement between the movement ring and top plate can be reversed. It is preferred, however, to provide the recess in the movement since machining of the parts of the movement are simplified.

Although the invention has been disclosed in connection with the specific details of preferred embodiments thereof, it must be understood that such details are not intended to be limitative of the invention except insofar as set forth in the accompanying claim.

I claim:

In a watch, the combination of a movement ring provided with an opening, a movement located within the opening, the movement having a flange adapted to rest upon the surface of the ring around the opening therein, Which flange is provided with a recess, and a rigid tongue carried by the ring and bent upwardly above the surface thereof to enter the recess. I

In testimony whereof; I have hereunto set my hand this 17 day; of June 1930, I EDWARD HOWARD. m V
