CARL WM. W. VON TIEDEMANN, OF GORTEZ, NEVADA.

WATCH-B OW.

To all whom it may concern:

Be it known that I, CARL M. vo1\ TIEDEMANN, a citizen of the United States, residing at Gortez, in the county of Lander and State of Nevada, have invented certain new and useful Improvements in IVatch- Bows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in watch bows and it has relation more particularly to a device of this character whereby the greater the strain on the bow, the tighter is its connection with the head or stem.

It is also an object of the invention to provide a novel device of this character which will be simple in construction, efiicient and advantageous in practice and comparatively inexpensive to manufacture.

IVith the above and other objects in view the invention consists of the details of con struction and in the novel arrangement and combination of parts to be hereinafter more particularly referred to.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters of reference denote corresponding parts in the several views and in which,

Figure 1 is a view in elevation of a watch showing the invention applied thereto. Fig. 2 is an enlarged fragmentary view partly in elevation and partly in section of a watch illustrating the connection between the bow and head, and, Fig. 3 is a modified form of invention showing means for attaching a bow to an article other than a watch.

In the drawings, 1 denotes a Watch cas- Specification of Letters Patent.

ing of any ordinary or preferred form having secured thereto the head or stem 2. The bow 3 is formed of a continuous piece of resilient wire of a desired weight and is bent into an approximate U-shape. Its free end portions at are bent back and inwardly upon themselves to form approximately V-shapes, the free end portion of each V being arranged on a curve 5 so that the free end portions can be readily inserted within the openings 6 in the head. It is the curve 5 that assures the effectiveness of the bow for when pull is made on the bow 3, the curve 5 will cause the free end portions to pass within the openings 6 and the greater the pull, it will be seen that the connection between the portions 4: and the stem will be the more positir ely assured.

In Fig. 3 is shown a bow applied to a stopper or plug and it might be well to further state that this form of bow can be employed to any device with equal facility. In this form of invention, the bow 7 has the bent portions 8 arranged and curved as in the form disclosed in Figs. 1 and 2 and the portions 8 project within recesses 9 in the stem projecting from the body 10, in this instance a plug.

I claim:

A pivoted watch bow extended beyond the pivots toward the watch, thence bent inwardly in substantially a V-shape and terminating in said pivots, whereby a pull on the bow will cause the pivots to tend to move inwardly to clasp the pendant.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
