LOUIS E. F. WACHTER, OF NEW YORK, N. Y.

I WATCH-BOW.

Specification of Letters Patent.

-' Patented July 1, 1919.

Application filed March 8, 1917. Serial No. 153,528.

To all whom it may concern:

Be it known that I, LOUIS E. F. WAOHTER, a citizen of the United States, residin in the city, county, and State of New ork, have invented certain new and useful Improvements in Watch-Bows, of which the following is a specification, reference being had to the accompanying drawings, illustrative of one particular embodiment of my invention.

My invention relates to bows for watches and more particularly to such made in a manner to facilitate their application and still give greater security of attachment of the bow to the watch than in the ordinary construction. In some forms the additional advantage is afforded of ready application and secure holding of the bow against any detachment when in normal position. Various other advantages will appear from the following description and will also be more fully developed in the practice of my invention.

In particular, the preferred form permits the slipping of the bow into engagement with the watch, such as suitable pendant parts, when the bow is in a relatively abnormal position, so that. when turned into any usual position it will be firmly attached; while at the same time any springing of the bow in any form of my invention is not such as to injure the shape or the structure of the metal.

In the present form of bow construction the bow ends engage a socket by a very slight projection, so slight that pressure or a twist will readily remove it in a manner popularly known as wringing a watch. Furthern'iore, if the recess is larger and the projection extends farther in, the bow must be sprung for insertion to an extent which frequently causes the bow to take a set or affects the structure of the metal and a special tool becomes necessary to reset the ends of the bow in a position so that the spring of the metal will hold them, but even when this is attempted it frequently leaves the bow loose and results in accidental detachment and loss or injury to the watch. Furthermore, when securely held by some known bow attaching methods, the detachment of the bow is inconvenient or impossible when such becomes necessary for purposes of replacement or repair. It will therefore be seen that the objects of my invention include means to overcome these various difiiculties, as well as others.

In the particular form of embodiment of my invention which I will now particularly describe, there is shown in the accompanying drawing the following:

A pendant in elevation with the pendant boat in part section, with bow in place showing a ball and socket connection between the bow and the boat.

In the drawing the bow A has the ends rounded as at P and P, and the inner ends of the socket Q and Q are rounded so that the ends of the bow have a ball and socket engagement to insure a full bearing, as dis tinguished from structures where the bow end is intended to have the cylindrical fit with the socket, which in cases of repair or replacement may not always be attained through variations in size. As shown, the rounded end P is placed in the seat of the socket and with the bow A turned at right angles to its normal position. The other end P being flattened is slid through the slot R edgewise, into the deep socket Q, and the elasticity of the metal causes it to spring to a firm seat at the bottom of the socket Q, with a partly spherical engagement,-thereby effecting a secure holding of both ends in deep sockets and the bearing at the bottom of the socket most advantageously adapted to accommodate or prevent wear and deterioration.

Depending upon the particular use and desires of the manufacturer, either one end or both ends may be specially formed, and for adaption to original equipment or for replacement or repair the bows may be of various forms and with or without a shoulder at the end. My invention may be enibodied in a great variety of ways, and changes in dimension and form may be resorted to without departing from the spirit of my invention, but what I claim and desire to secure by Letters Patent is:

In a watch, an elongated pendant terminating in part sphericalv ends, a part spherical socket in each end, a slot on one side of one of said and sockets, a how, part spherical ends on said bow, one of said how ends begreater diameter than the adjacent portion 10 ingof greater diameter than the adjacent of the bow.
