WATCH-MOVEMENT BOX.

SPECIFICATION forming part of Letters Patent No. 268,884, dated December 12, 1882.

Application filed September 6, 1882. (No model.)

[0 all whom it may concern: V

Be it known that I, WICKTOR A. GUSTAFS- mm, of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Watch Movement Boxes, of which the following is a full, clear, and exact description, that will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, forming a part of this specification.

This invention relates to improvements in small metal boxes or cases, in which the naked watch -movements are packed for shipment from point to point, or when carried as samples by traveling salesmen, and is so constructed and arranged as to protect the delicate mechanism from injury.

Figure 1 is a top view with the cover removed. Fig. 2 is a vertical section in the plane 2 2, Fig. 1, the cover being in place; and Fig. 3 is a bottom view'of the inner inclosing-case.

Referring to the drawings, A represents the outer inclosing case, A the removable cover thereto, and B the inner case, which forms the receptacle proper for the watch-movement.

The radiating spring-arms a a a a project outward from a common center, the body of whichis provided with the square apertuiea for the reception of the rivet M, which has a neck of a corresponding shape and secures the inner and outer case relative toeach other. The outer ends of the arms a are provided with the rectangular slots 1), and are secured to the under side of the inner case, B, by means of the pins d, which form of constructionreadily permits of an outwardmovementof the springarms a when a pressure is received on the box or case from above. The inner ends or body, forming the spring-arms a, are bent downward from the under side of the case B, as shown in Fig. 2 of the drawings.

The lower ends of the retaining-clasps C G are secured to the under side of the case B, as shown in Fig. 3 of the drawings, and then bent around at right angles to conform to the shape of the box, the upper ends being made to project above the edge of the case, as shown in Fig.2ofthedrawings. Theupperendsofthese clasps are split down a little way to form bifurcated ends, the part D being turned down in a horizontal plane projecting inward, so as to overlap and engage with the edge of the dial-face for the purpose of securely holding the watch-movement in place. The other part, D, of the split end projects upward in a vertical plane, as shown in Fig. 2 of the drawings, and serves to prevent the cover A from being forced down so as to come in contact with and injure the upper end of the center staff and dial -face. The upwardly projecting end or ends D also readily permit of the retainingclasps G 0 being conveniently forced back for the purpose ot'inserting or removing the watchmovement from the case B.

In shippingwatch-movements it frequently occurs that the cover of the outer inclosingcase is forced down by an accidental blow of pressure and the works seriously injured; but by this form of construction and arrangement all this is prevented, as the cover, when forced down too far, comes in contact with the upward-projecting ends D, which has the effect of forcing down the inner box, the springarms underneath spreading outward and readily yielding to this change of position, so that it is not pos sible to injure the works inclosed in the inner case under ordinary circumstances, there being suiiicient space left between the inner and outer case on all sides to prevent any indentation from reaching the inner case.

I claim 1. The combination, with the outer case, A, of the inner case, B, and the radial arms a a a or, provided at the outer ends with the elongated slots b, and secured to the case B by means of the pins (1, adapting these parts to have a lateral adjustment, substantially as and for the purpose set forth.

2. The combination, with the inner case, B, of the retaining-clasps O G, the upper ends thereof being split to form the part D, which is turned downwardin ahorizontal plane, while the part D projects upward in a vertical plane, Substantially as and for the purpose set forth.
