3612/ gduai Patented June 2, 1931 UNITED STATES PATENT OFFICE BEN OGUSH, OF NEW YORK, N. Y., ASSIGNOR TO KATZ & OGUSH, INC., OF NEW YORK, N. Y., A CORPORATION OF. NEW YORK CONNECTION DEVICE FOR WRIST WATCHES Application filed. June 5,

This invention relates to an improvement in a connection device for a wrist watch and has for its object to provide a means which shall form a part of the wrist-encircling member or band; which shall be expansible to enable the wrist-encircling member to closely and properly fit the wrist, and which shall be of simple and sturdy construction.

A further object of the invention is to provide an expansible connection means for wrist watch bracelets which shall be ornamental in appearance and enable a bracelet of one size to fit wrists of varying diameters without requiring the usual adjusting means.

lVith these objects and such other objects as may hereinafter appear, in view, I have devised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claim appended hereto.

Reference is to be had to the accompanying drawings forming a part hereof in which Figure 1 is a plan view of my improved connection device, showing a part of the wrist-encircling member of the watch;

Figure 2 is a view of the underside of the structure disclosed in Figure 1;

Figure 3 is a perspective View of one end of the wrist band showing the spring-pressed yoke;

Figure 4 is a sectional view on the line 4 of Figure 1,looking in the direction of the arrow; and

' Figure 5 is a sectional View on the line 55 of Figure 1, looking in the direction of the arrows.

In the embodiment of my invention disclosed in the drawings, 1 indicates the body portion of the connection member. The same is capable of being made in many ornamental shapes. It is preferably made from sheet metal and may be set with precious stones if desired. For the purposes of simplicity in illustration, I have omitted all ornamental embellishments and have shown the body portion 1 as consisting of a shell-like member having outwardly splayed arms 2 and 3 which are secured to or form an integral part of a tubular member 4 that fits between the spaced lugs 5 and 6 of a watch 7. A connection pin, not shown, passes through the tu- 1929. Serial no. 368,469.

bular member'lz and thus secures the member 1 to'the watch in the conventionalmanner.

As heretofore stated, the member 1 is in the form of a hollow shell and secured within it, or forming an integral part of it is an elongated tubular member 8. This tubular member 8 contains a coil spring 9 which has one of its ends bearing against a closed end 15 and its opposite end resiliently pressing against a cross-bar 10 provided on a yokeshaped member 16 that projects from the end of the wrist band 13. Said wrist band 13 is shown in Figure 1 as being of articulated form, the same consisting of a number of linked elements 14. This or any other type of wrist band may be readily used.

The cross-bar 10 provided on the yoke 16 is movable in slots 11 provided in the opposite side walls of the tubular spring-containing member 8.

From the foregoing, the manner in which my connection member operates will be readily understood. The spring 9 normally tends to hold the device in its closed position as disclosed in Figures 1, 2 and 4 of the drawmgs. In this position, the end 17 of the wrist band 13abuts against the end 18 of the body member 1. To expand the wrist band, it is simply drawn outward against the tension of the spring 9 as indicated in dotted lines in Figure 2. The wrist band may be thus expanded to enable the same to he slipped over the wrist.

Guide pins 19 extend between the sides of the tubular member 8 and the side walls of the member 1. These pins 19 enable the side arms of the yoke 16 to uniformly move back and forth as required when the wrist band is expanded or contracted under the pressure of the spring 9.

As heretofore stated, the device may be made in many ornamental forms, and the mechanism is wholly consolidated within the shell-like connection member 1. It is of sturdy construction and unlikely to get out of order and even in case of breakage of the spring, it is not possible for the parts of the wrist-encircling memberto separate so that the watch and wrist band cannot in any manner become lost.

What I claim is:

A device of the class described comprising a connection member having an open-sided casing provided with a pair of side Walls, means on said casing for attachment to a wrist watch, a tubular spring-container provided on said connection member and exposed at the open side of the casing, a wrist band, a yoke thereon provided with side armswhich lie between the side walls ofthe casing and the spring-container, a cross-bar on said yoke, a pair of slots in the side Walls of the spring-container in which said cross 1 bar is movable, a spring Within the springcontainer exerting pressure on the cross bar,

and guide means extending across the open side of the casing between the spring-conta1ner and walls of the caslng for gmdmg V the side arms of the yoke during their sliding movement,

Signed at the city, county and State of i NewvYo-rk, this 4th day of June, 1929.

BEN OGUSH.
