HANDCUFF.

SPECIFICATION forming part of Letters Patent N 0. 670,251, dated March 19, 1901.

Application filed. April 30, 1900.

T0 ctZZ whom it may concern.-

Be it known that I, FREDERICK J. SoHIELE, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Handcufis, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in handcuffs, and has for its object the production of a simple and practical device of the character mentioned in which the movable jaws are automatically locked in their inoperative and operative positions and are automatically forced into operative position when said device is placed in position upon the wrist or other member of the body.

To this end the invention consists in the combination, construction, and arrangement of the component parts of a handcuff, as hereinafter fully described, and pointed out in the claims.

Figure l is a plan view, partly in section, of a handcuff embodying my invention. Figs. 2 and 3 are plan views, partly broken away, of the adjacent hinged ends of the parts seen in Fig. 1, the jaws being closed in Fig. 2 and open in Fig. 3. Figs. 4: and 5 are inner face views, respectively, of the parts seen in Figs. 2 and 3. Figs. 6 and 7 are sectional views taken, respectively, on lines 6 6 and 7 7, Figs. 2 and 3. Figs. 8 and 9 are isometric views of the adjacent portions of the jaws, and Fig. 10 is an isometric view of the locking member for holding the jaws in their inoperative positions.

Referring to the drawings, Ct I) represent oppositely-arranged jaws having corresponding ends hinged together and their opposite ends movable toward and away from each other and provided with engaging shoulders detachably interlocking with each other. The hinged ends of the jaws a b preferably consist of enlarged cylindrical portions 0 d, arranged one above the other, and are provided with hollow substantially central hubs cf, telescoping with each other for forming a pivotal bearing upon which the sections a I) move. The portions 0 d are usually provided with recesses g h, extending outwardly from their adjacent faces for forming annular Serial No- 145806. (No model.)

flanges M, which are arranged substantially concentric with the hubs ef. The portions of the jaws a. b adjacent to the cylindrical portions 0 d are preferably formed of greater thickness than the depth of the flanges t'j, extend in opposite directions beyond the adjacent faces of the flanges, and are provided with shoulders is Z for engaging similar shoulders m n, projecting from the peripheries of the cylindrical portions 0 d for limiting the outward movement of the free ends of the sections a b. The inner portions of the flanges 't'j of the cylindrical portions 0 d are formed of less height than the remaining portions of said flanges for forming a slot 0 and shoulders 19 g, which form the end walls of the slot 0, and are movable toward and away from each other as the sections a d are closed and opened.

1' s are cut-outs extending through the inner walls of the flanges and preferably beyond the adjacent face of the portions of the flanges in which the slot- 0 is formed, are movable into and out of registration with each other, and preferably for:n continuations or extensions of the slot 0 for receiving a locking member presently described.

The sections a b may be held in their assembled position by any desired fastening means, here shown as consisting of a yoke having separated ears to a, engaged with the opposite faces of the cylindrical portions 0 d and provided with apertures alined with similar apertures extending through the outer walls and hubs e f of said portions 0 d, the aperture of one of the ears being threaded for receiving a screw which is passed through said apertures and hubs and serves to hold the adjacent parts together. The free ends of the sections a b are automatically forced to their operative or closed position by a suitable spring, as 12, arranged between the portions 0 (Z of the sections a b within the recesses g h and having its intermediate portion encircling the hubs e f and its opposite ends engaged with suitable shoulders, as apertures w w, formed, respectively, in the flanges z'jand communicating with the recesses g h.

The sections a b are held in their open or inoperative position by a suitable locking and lock the sections in their open or inop erative positions. The inner and outer ends of the plunger are preferably formed of greater area or width than the slot 0 and the cut-outs r s, the inner enlarged end being arranged in the recesses 9 hand adapted to engage the inner faces of the flaugesij for limiting the outward movement of the plunger.

The outer end of the plunger is formed of substantially the same contour as the adjacent portions of the sections a b, and when said sections are locked in their inoperative position the inner face of said enlarged outer end of the plunger is separated from the adjacent faces of said sections in order that when desired to apply the handculf to the wrist or other member of the body it is only necessary to slightly press the outer face of the plunger against the wrist or other member, whereupon the shoulders 'g y are forced inwardly out of engagement with the side walls of the cut-outs r s and the free ends of the sections ab are immediately and automatically closed upon the wrist or other member by the spring 1;.

The means for automatically forcing the plunger into operative position for locking the sections (L b in their open position preferably consists of a spring .2, arranged in one of the recesses g h and having its intermediate portion engaged with the inner face of the enlarged inner end of the plunger a: and its opposite ends engaged with the flange or flanges v) j of the cylindrical portions 0 d. The free ends of the sections a b may be locked in their closed position by anydesired means, here shown as consisting of a springactuated catch 2, provided in one of the sections and adapted to engage either of a series of notches or shoulders 3, formed on the other of said sections, as seen in Fig. l. The catch 2 may be forced out of operative position by any desired means, as a key 4, also seen in Fig. l. The means for locking the free ends of the sections a b in their closed positions forms no part of my present invention, and it is therefore unnecessary to further illustrate or describe the same.

The operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be noted that considerable change may be made in the detail con struction and arrangement of the parts herein shown and described Without departing from the spirit thereof. Therefore I do not limit myself to the precise construction and ar rangement thus shown and described.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-
