ART-GLASS JOINT.

Application filed September 7. 1926.

The object of this invention is to provide a substantial and convenient joint connection between metal window mullions at their intersections, such that one of the mullions may extend continuously across the window frame, for maximum strength, and those running in the opposite direction can be attached at any position along the continuous one or ones, and can be changed at will.

A further object is to provide a connection which can be entirely or partly removed from working position for the sufficient separation of the mullions to allow for the assembly of the glass in the mullion channels or grooves, and then slid on the continuous mullions into final assembly position of the others.

I accomplish the above, and other objects which will hereinafter appear, by the means illustrated in the accompanying drawing, in which Fig. 1 is a front elevation of a window utilizing my invention;

Fig. 2 is a plan view of a metal blank slotted at the corners preparatory to bending the resulting ears into holding devices;

3 shows the same after the ears are bent into holding devices;

Fig. 4; shows the opposite side of that illustrated in Fig, 3;

Fig. 5 is a perspective view of a continuous mullion with a pair of my improved clips in position for holding a horizontal iuullion, one of which appears in full lines and the other forming its ezuension, is indicated by dotted lines; and

Fig. 6 is a detail looking at the sides and cut 3, respectively, of mullions joined by my invention.

Like characters of reference indicate like parts in the several views of the drawing.

All of the mullioins are til-shape in cross section, the channels being where the edges 0t the glass are secured and held by the flanges which define the channels. The glass will be retained without additional means, but may be further secured by putty. The mullions as now commercially procurable are bent to form out of sheet metal strips of zinc, copper, brass or the like.

In the embodiment of my invention here illustrated, the continuous mullions 9 extend from side to side of the window frame 8 Serial No. 133,932.

and the vertical or cross mullions 7 only extend between the continuous one 9, and are attached to the latter at their intersections by two of my joint pieces 10.

The joint pieces 10 are each formed from a square blank of sheet metal in which slots 11, from each corner toward the center of the plate, are made, thereby producing eight ears of acute outer angular form all of which are next bent in the same direction, int-o parallelism with the body of the piece, thereby producing eight locking cars 12, arranged in four pairs, as shown in Fig. 3. The ears of two diametrically opposite pairs receive one side of an H-shaped mullion 7, between them and the body 10 with a sliding fit, and the ears of the other two diametrically opposite pairs receive one side of the respective ends of two H-shaped ears or horizontal mullions 9.

The joint pieces are used in pairs, one for each side of the H-shaped mullions, and they can be slidingly moved to any convenient working position along the continuous mullions 7, which is particularly desirable in setting the glass 13.

Iaving thus fully described my invention, what I claim as new and wish to secure by Letters Patent of the United States, is

1. In a corner fastener for window mul-- lions, a substantially rectangular plate slotted from each corner toward the middle of the plate forming apair of angular cars at each corner, the ears of each. corner pair being bent on the same side of the plate but in opposite directions from each other to receive the flanges of mullions with a sliding lit.

2. The combination, with a sash having mullions which are H shaped in cross section, some of said mullions extending continuously of the window and others in opposite directions between pairs of the continuous mullions, of a fast ner at the joints between and connecting the mullions, comprising one or more plates at each joint having two pairs of diametrically opposite ears in pairs, adapted to slide on the continuous mullions and to receive and hold the ends of the other mullions.

In testimony whereof I aflii: my signature.
