PATENT BRACELET.

SPECIFICATION forming part of Letters Patent No. 449,103, dated March 31, 1891.

Application filed October 10, 1890. Serial No. 367,747. (No model.)

To all whom, it may concern: Be it known that I, CARL BAOHEM, a subject of the Grand Duke of Baden, residing at Pforzheim, in the Grand Duchy of Baden, German Empire, have invented certain new and useful Improvements in Bracelets, of which the following is a full, clear, and exact specification.

My invention relates to improvements in bracelets, in which the bracelet is divided into two branches connected at one side by a hinge of remarkably simple and practical construction and at the other side by a fastening device of equally simple and practical construction. The whole bracelet is distinguished by the perfect smoothness of its surface, so that no parts at all jut out from it. Iattain these objects by the mechanisms illustrated in the accompanying drawings, in which similar letters denote similar parts throughout the several views, and in which Figure l is a side view of the hinge drawn to a larger scale and the branches in section, taken on the line a z of Fig. 1. Fig. 1" is a side view of thefastening device drawn to a larger scale and the branches in section, taken on the line 0 w of Fig. 1. Fig. 1 is a side view of the bracelet nearly closed. Fig. l is an upper view of the bracelet completely closed. Fig. 1 is a full view of the bracelet completely opened, showing another form of the fastening device. Fig. 2 is another full view of the bracelet nearly closed, showing the same form of the fastening device. Fig. 3 is a side view of the bracelet completely closed and partly in elevation, showing the same form of the fastening device and taken on the line a: y of Figs. 1 and 2. Fig. 4 is a full view of the bracelet completely opened, showing the third form of the fastening device. Fig. 5 is afull view of the bracelet nearly closed, showing the third form of the fastenin g device. Fig. 6 is a side view of the bracelet completely closed and partly in elevation, showing the third form 'of the fastening device and taken on the line 0 s of Figs. at and5.

The fastening device of the bracelet is made as follows: The ends of the branches opposite the hinge are sloped and covered with oblique plates 19 19 Fig. 1, one of which 19 is slitted, and the other 19 is provided with a projection or nose a. When the opened bracelet is to be shut, the branches Z) Z) are moved against each other and the upper curved rim 1" of nose n is pushed against the under partof plate 12 as shown in Fig. 1. Now the branches 1) b will act as springs in such a manner that they withdraw a little, thus allowing nose n of plate 19 to slide upon the oblique plate 19 and then to enter the slit s in that plate. The bracelet is thus firmly closed, the nose n being held within the slits by the elastic power of the bracelet itself.

In order to open the bracelet, the branches of it are moved in a direction contrary to that in which the bracelet was shut before. The nose n is thus forced to slide upon its under curved rim out of the slit 3 tillit leaves the slit and slides down on the under part of the oblique plate 19 The two parts of the fast ening device are out of connection now, and the bracelet may be opened completely by simply continuing the turning of the two branches. I

It might be that people not perfectly acquainted with the peculiarity of the fastening device described above would try to open the bracelet by bending the branches rectangularly to the direction in which they ought tobe turned properly, and a break of the hinge would inevitably be the result. For avoiding incidents of such kind two other forms of the nose have been constructed, one of which is represented by the Figs 1 to 3 and the other by the Figs. li-to 6. The nose 7?. is, in the first case, Figs. 1 to 3, formed likea hook, which is'pressed into the slit 3 in exactly the same manner as described formerly. hen trying mistakenly to open the bracelet in wrong manner by drawing the nose or hook against the inner surface of the oblique plate 19 the wrong direction of the pull is turned automatically in the right one by means of the inner curved rim of the nose a sliding along the upper small rim of the slit .9 in the plate 19 thus opening the bracelet a little and showing the right way to open it completely. In the third form (illustrated by the Figs. 4 to 6) the nose is of somewhat different shape and near its base provided.

With a slits. When pressing the two branches of the bracelet together in the usual manner2'. e., when the nose or hook enters the slit in the manner explained above-the nose catches with its slit behind the inner surface of the plate p It is impossible 110w by any means to open the bracelet in a wrong way, as the hook or nose with its slit 5' holds the branches 1) b firmly together, and it is equally impossible to break the bracelet, as it cannot be opened except in right manner.

The hinge, finally, of the bracelet is made as follows: Two round metal plates 19 p, of somewhat larger diameter than the metal tubes, Fig. 1*, are laid one upon the other. Two metal plates on m, of smaller diameter, are laid now upon one side and the other on the opposite side of the plates 1) p. The four plates, each of which is provided with a central aperture, are connected by a rivet r in such a manner that the plates 1) 2) may be turned in contrary direction without any considerable effort. Then the two branches 1) b of the The branches are firmly connected now at one end, and the other ends may be moved against or from each other, according as the bracelet is to be put on or taken 01f.

Having thus fully described the nature of this invention, what I desire to secure by Letters Patent of the United States is- In a bracelet, the combination of the two branches of the bracelet, the ends opposite the hinge being sloping and covered by oblique plates, one of which is provided with a nose or equivalent fastening device and the other with a slit, the nose being adapted to enter the slit, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscrib- V ing witnesses.

CARL BACIIEM.
