CORNER OR FASTENING FOR SHOW-CASES.

SPECIFICATION forming part Of Letters Patent No. 722,588, dated. March 10, 1903.

Application filed August 23,1902. Serial 110 120,831. (No model.)

To all whom it may concern.-

Be it known that I, OTTO C. KADE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,have

invented new and useful Improvements in molding, as well as frames for holding glass plates at points intermediate of their edges, maybe entirely dispensed with, and thus permit the production of an attractive show-case of a strong and durable nature with a minimum cost in the manufacture of the same.

The invention consists in" the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a portion of a show-case composed of glass plates and illustrating one of the improved corners applied thereto. Fig. 2 is a section through the corner of a portion of the show-case shown by Fig. 1 and the improved device taken in a diagonal plane. Fig. 3 is a detail perspective view of the improved corner or fastening, showing the parts thereof separated. v

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numerals 1 and 2 designate side and end plates, and 3 a top plate, of a show-case, said plates being of glass and having the exposed edges suitably finished. To protect the side and end plates, the edge portion of the top plate, at the sides and ends thereof, extends over the members of the show-case below, and thereby also forms an ornamental case. The improved corner or fastening consists of a stifi-metal corner-socket at, shaped to embrace a portion of the side,-end, and top plates 1, 2, and 3 and also having a hollow head 5 to compensate for the edge extension of the top plate 3. The corner or fastening 4 is of approximately'triangular form, and extending downwardly and inwardly at an angle of inclination from the upper angle 6 of the improved device is a bolt-rod 7, which is passed through suitable small openings 8, formed in the adjacent portions of the plates 1, 2, and 3. A triangular clamping-block 9 is fitted over the inner end of the bolt-rod 7, said block having an outwardly-flared socket 10 to permit it to be applied over the said bolt-rod and remain in loose connection with said rod until a clamping-nut 11 is applied to the inner screw-threaded extremity of the bolt-rod and brought firmly to bear against the inner face of the block 9. When the nut 11 is applied and contacts with the block 9, the later is drawn upwardly into place and firmly bears at its three sides, respectively, against the side, end, and top plates 1, 2, and 3 and is located far enough away from the intersecting terminations of said plates at the angle thereof forming the corner to prevent fracture of the plates. When the nut 11 is turned against the block 9 and the latter caused to closely bear against the inner side of the plates-adjacent to their angle of intersection, the improved corner or fastening 4 is tightly drawn against the outer portions of the said plates, as clearly indicated by Figs. 1 and 2. Owing to the approximately triangular form of the socket or fastening 4, the plates 1, 2, and 3, adjacent to their angles of intersection, are immovably held, and the side and top members of the socket 4 closely bear against said plates, and'the hollow bead snugly receives the extended edge portions of the top plate 3. By this means all the parts of the improved corner-fastening are reliably and immovably held in engagement with the corner of the case, and after all the corners are applied to a case the latter is held rigid with a strength equal to that of cases employing frames or moldings to receive the edges of the glass plates.-

The improved device is also very convenient in view of the rapidity with which it can be applied or detached in setting up or tak-.

ing down show-oases, and as it does not require the knowledge of a skilled person to apply the corner the show-case composed of glass plates without side and end frames or moldings can be reduced and packed closely during transportation or storage and afterward easily set up in operative position.

It is proposed to make all the parts of the improved corner or fastening of metal and suitably ornament the same, particularly the socket 4, and for the purpose of practically applying the clamping-block 9 to the plates the side edges thereof are beveled or cut at an angle of inclination, as clearly shown by Fig. 3. As a further means of facilitating the application of the clamping-block 9 the inner portions of the corners are cut away to form curved bevels, as at 12, and in view of the formation of the socket 10, which is located in the center of the block 9, the latter will automatically adjust themselves to the inner faces of the plates 1, 2, and 3 when applied.

To accommodate the application of the improved corner or fastening to cases of various sizes, changes in the proportions, dimensions, and minor details of construction may be resorted to without in the least departing from the principle of the invention.

Having thus fully described the invention, what is claimed as new is 1. A corner or fastening of the class set forth comprising an approximately triangular socket having depending sides and a top member and also provided with a bolt-rod extending from the upper angle thereof at a downward inclination, a triangular-shaped clamping-block to loosely fit over the said bolt-rod, and a clamping-nut removably engaging the said rod.

2. A corner or fastening of the class set forth comprising a socket to fit over the exterior of the corner of a case or the like and provided with an inwardly-extending and downwardly-inclined bolt-rod, and means for engaging the said bolt-rod within the plane of the socket to firmly hold the latter in applied position.

3. A corner or fastening of the class set forth, com prising asocket member of approximately triangular form and having an upper surrounding hollow bead, and means for securing the said socket in applied position.

In testimony whereof I affix my signature in presence of two witnesses.

OTTO C. KADE.
