.SPECIFIGATION forming part of Letters Patent No. 537,417, dated April 9, 1895.

` i Application led May 31,1893. Serial No. 476,074. (No model.)

-JZ'o all whom it may concern.-

Be it known that I, OswALD HEINRICH, a subject of the Emperor of Germany, residing at Mittelwalde, in the Province of Silesia,

5 Germany, have invented certain new and useful Hinged-Joint Links for Joining Walls of Boxes or Oasings, of which the following is a specification.

This invention relates to a hinged joint-linkV xo for joining walls of boxes and casings and the object of this improved joint-link is to afford the possibility for joining walls of boxes and casings in any position to each other.

Each joint-link consists of two plates catch- 15 ing into each other with sockets and held in position by means of a pin passed through the said sockets. The other edges of the plates are fastened to the edges of the walls to be joined.

In the accompanying drawings: Figures 1,

ln and lb show one form of my improved fastening. Figs. 2 and 2, 3 and 3 and t and 4fl show modiiied forms of the means for fastening the joint to the box. z 5 In Figs. l, la and lb one form of my hinge connection is shown consisting of eyes or sockets a with intervening spaces adapted to receive like eyes, the connection between the two being made by a rod upon which the eyes pivot.

My invention relates particularly `to the manner of securing the eye sections to the box or case.

.As shown in Fig. l, the eyes or sockets are 3 5 formed on the edge of the plate a, of metal and the plate is secured to the box c, as shown in Fig. 1b, by bending back upon itself the lower part of the plate a clamping the material of the box or case which is exible between the parallel surfaces.

As shown in Fig l instead of forming the eyes on the edge of the plate they may proj ect from the surface.

In Figs. 2 and 2a the lower edge of the plate is doubled back with the edge of the case or 45 box between the opposing surfaces, and the end of the doubled part together with the projection forces the material of the case into recesses as shown in Fig. 2f.

In Figs. 3 and 3, the plate is provided with 5o a turned up lower edge having a series of projections like saw teeth and the doubled edge of the box or case engages with these proj ections.

In Figs. 4C and 4 the lower edge of the plate 55y a and the upper edge of the case are rolled together as shown in Fig. 43.

In combination with the edge of a box or case, a joint plate having its lower end folded between the doubled upper end of the box or case and a series of eyes on its upper edge, substantially as described.

Signed at Breslau, Province of Silesia, Empire of Germany, this 19th day of April, 1893. 65-

OSWALD HEINRICH.
