METAL FRAME CONSTRUCTION FOR \R INIDOW'S AND THE LIKE.

Application filed October 18, 1922, Serial No. 595,374. Renewed April 3, 1926.

This invention relates more particularly to a class of frames for supporting plates of glass.

My invention has for its object primarily to provide a metal frame designed to be employed for mounting in store fronts, show cases and elsewhere plates of glassin a manner whereby the glass plates will be firmly held against tendency to accidentally shift in therframe, in order to prevent liability of breakage from the force of currents of wind as Well as allowing for expansion and contraction of the glass during hot and cold weather conditions, and which is of a form whereby unusually limited portions of the glass are obscured byethe frame. The invention consistsessentially of a metal stiffening bar having lengthwise thereof two flange members extending in opposite directions, and these flange members may be disposed on relative diverging planes or on similar relative planes for use as the corner stile or as the central stile of the frame of a store window or show case and elsewhere so'that the marginal parts of opposed edges of two plates may be applied in lapping arrangement on the flange members. A separate metal clamping plate of a formation corresponding to the shapes of the flange members is provided for engaging the surface parts of the glass plate opposite to the flange members, and means is provided for releasably locking the clamping plate to the stiffening bar whereby the glass plates will be held in the frame.

A further object of the invention is to provide a metal frame of a simple, efficient and durable construction which may be made in any appropriate shape and size.

With these and other objects in view, the invention will be hereinafter more fully described with reference to the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, and will then be pointed out in the claim at the end of the description.

In the drawing, Figure 1 is a fragmentary view showing the manner of using my improved metal frame for erecting a window.

Fig. 2 is an enlarged fragmentary view showing a detail section taken through the form of the device for providing the corner stile of a window frame.

Fig. 3 is an enlarged fragmentary view showing a detail section taken through a a store window, show case and elsewhere for fastening the oppose-d edges of plates of glass, as 13 and 14, disposed at angles, as shown in Figs. 1, 2, 3, the metal strip at the edges of the slot 12 of the tubular member 11 is bent to provide two flange members 15 and 16 which are disposed on relative di- 4 verging planes or at suitable angles according to the relative positions of the plates of glass. In the tubular member is tightly driven a core, as 17 ,which may be in the form of a solid metal rod, as shown in Figs. 1 and 2, or the core may be in the form of a metal tube, as indicated in Fig. 3, for serving to reinforce the tubular member 11.

Associated with the stile member 10. is a separate clamping member or plate 18 which is also preferably formed of a strip of sheet metal having spaced parts intermediate its side edges bent lengthwise to provide a spanning part, as 19, and two flange members, as 20, 21, disposed in opposite directions from the side edge portions of the spanning part on diverging planes so that these flange members 20, 21 are in spaced parallel relation to the flange members 15, 16 of the stile member 10. When the glass plates 13, 14 are mounted in the frame the marginal portions of the opposed edges of the plates are arranged between the flange members 15, 16 of the stile member and the flange members 20, 21 of the clamping plate 18 so that the opposed edges of the glass plates are in spaced relation. The spanning part 19 of the clamping plate is of a width whereby it will bridge the space between the glass plates as well as being disposed crosswise in spaced relation to the slot 12 of the tubular member 11 of the stile member 10.

hen the frame construction is made to serve as a central stile, as B, for a store window, show case and elsewhere, for fastening the opposed edges of plates of glass disposed on similar relative planes, as shown in Figs. 1 and 4, the flange members, as 22, 23, of the slotted tubular member 11 of the stile member 10 are disposed in opposite directions on similar relative planes, instead of being disposed on diverging planes. The clamping plate 2a is in the form of a flat strip of metal disposed in spaced parallel relation to the flange members 22, 23, and, as illustrated, the plates of glass are arranged between the clamping plate 24 and the flange members 22, 23 so that their oppo's ed edges are spaced from each other.

Serving as means for fastening the plates of glass between the clamping plate and the stile member of the frame construction, one or moi'e locking elements, as 25, are provided. The locking elements are of similar formations, and each element has a threaded rod or bolt 26 with one of its ends being screwed in a threaded hole provided in the metal core 17 of the tubular member 11 of the stile member 10 so that the second end portion of the rod extends through the slot 1:2 of the tubular member as well as extending between the glass plates and through a hole provided in the clamping plate. On the central part of the rod is a nut, as 27, which is screwed into engagement with the edges of the slot 12 of the tubular member 11 of the stile member 10 to prevent tendency of the rod to accidentally shift from its normal position, and on the end of the rod protruding beyond the clamping plate is a thumb nut 28 which is screwed into engageinent with the clamping plate. The plates of glass are thereby held against liability of accidentally moving in the frame to pre vent danger of breaking under strong currents of wind, as well as being mounted to allow for expansion and contraction of the glass plates under varied weather conditions, besides being easily removable from the frames occasion may require.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore, I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination, in a frame construction as characterized, of a stile member hav ing a slotted tubular member with two flange members disposed in opposite directions from the edges of the slot, a separate apertured clamping plate spaced from the flange members crosswise of the slot of the tubular member, a bar in the tubular member of the stile member and having a threaded hole in register with the slot of the tubular member, a threaded rod having one of its ends screwed in the ho'leof the bar and projecting through the slot of the tubular member and through the aperture of the clamping plate, a nut screwed on the bolt for releasably fastenin the clamping plate when adjusted relative to the flange members of the tubular member of the stile member, and a second nut screwed onthe bolt into engage ment with the flange of the tubular member.

This specification signed this 17th day of October A. D. 1922. I I
