SHOW-WIN DOW STRUCTURE.

Application filed July 22,1910. Serial No. 573,249.

Structures, of which the following is a full,

clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to store-fronts, show-windows and similar structures which clamping members that bear against the outer face of a plate of glass and also against the stationary frame in which the glass is arranged for retaining the glass in position.

One object of my present invention is to provide means of novel construction for holding the outside clamping member tightly against the glass and against the stationary frame in which the glass is arranged.

Another object is to provide a glass-retaining means of novel construction that exerts an even clamping pressure on the glass and which can be set up easily and without liability of cracking or breaking the glass.

Another object is to provide a novel support for the inside clamping member which bears against the inner face of the glass, said support being so designed that the inside clamping member can be adjusted to accommodate glass of difl'erent thickness. And still another object is to provide a glassretaining means comprising an outside clamping member, an arm projecting inwardly from said member beyond the edge of the glass, and a plurality of adjustable devices cooperating with said arm for exerting. pressure on said clamping member in two different directions.

Other objects and desirable features of out.

Figure 1 of the drawings is a perspective view illustrating my present invention; Fig. 2 is a vertical sectional view taken on approximately the line 2 2 of Fi 1; Fig. 3 is a perspective view of one of t e supporting members arranged on the inside of the window opening for supporting the inside my invention will hereinafter he pointed clamping member and also the devices which illustrating one of the capsthat are arranged over the joints between the'ends of the outside clamping members; Fig. 5 is a perspective view of the. inside supporting member that'carries the devices which draw said cap into engagement with the outside glass-clamping member; 6 is a detail sectional view of an outside glass-clamping member provided -with an' inwardly pro ecting arm which is adapted to be engaged by the devices that draw said member into operative position; and Fig. 7 is a perspective view of a pressed metal key.

- Referring to the drawin 's" which illustrate the preferred form 0 my invention, A designates the sill or lower cross-piece of a stationary frame in which plates of glass B are arranged, said plates being supported by blocks or other suitable devices, not shown, such as are generally used for this purpose. Outside clamping members C are arranged in engagement with the outer face of the glass and with the stationary frame A for retaining the glass in position, and caps or covers C are arranged over the joints formed between the ends of said outside clamping members G. The outside clamping members C may be of any preferred shape or design but I prefer to use pieces of molding provided with vertically disposed flanges 1 and? that project inwardly toward each other, as shown in Fig. 1, so as to form lugs or stops which metal, pressed or drawn sheet metal, or they can be formed by two pieces of molding mitered together. The keys 3 are provided with arms 4 which project inwardly beyond the glass, and means is arranged on the in- Specification of; Letters Patent. Paflmnjgfl Nagy, 1%, 1911,

side of the opening which the glass closes for cooperating with said arms to exert pressure on the outside clamping members in two difi'erent direct-ions, namely, inwardly against the glass and downwardly against the stationary frame A. While I have herein used the terms inwardly and downward-1y. to,indicate the direction in which the outside clamping member is moved, it will, of course, be understood that the clamping member which is arranged at the upper edge of the glass will be drawn in wardly and upwardly, and the clamping members which are arranged at the side edges ofthe glass will be drawn inwardly and sidewise. Therefore, I do not wish it to be understood that my invention is limited to a structure in which the outside clamping member rests upon the sill or cross-piece of the stationary frame in which the lass is arran ed.

T e means w ich cooperates with the arms 4 on the keys 3 to draw the outside clamping member inwardly and downwardly consists of a plurality of adjustable devices cooperating with each arm and mounted in a stationary member D that is arranged on the inside of the glass adjacent the lower edge of the same. These supporting members D which are preferably formed of cast metal are spaced certain distances from each other and are securely connected to the stationary frame A. Each of said members D is provided with a vertical wall 5 through which fastening devices pass to connect it to the frame A, a lug 6 that projects forwardly from said verticalwall, ahorizontally disposed flange 7 projecting forwardly from the upper edge of said vertical wall, and a lug 8 carried by said flange and arranged in alinement with the lug 6. The arm 4 on the key rests on the lug 6, and said arm is provided with an opening 9 which receives a tapered head on an adjusting device 10 that is mounted in a screwthreaded openin in the lug 6. Said tapered head is provide with a slot, as shown in Fig. 1, for receiving a screw-driver or other suitable tool for turning said device, and an opening 9 is formed in the horizontal flange of the member D in alinement with the device 10 so as to enable it to be gotten at easily. When the device 10 is screwed downwardly the tapered head thereon will bear against the wall of the opening 9 in the arm 4 on the key 3 and thus operate to draw the outside clamping member C inwardly into intimate engagement with the outside face of the glass, the vertical wall 5 of the supporting member D being providedwith a slot 11 through which the inner end of the arm 4 can ass. Means separate and distinct from t e device 10 is provided for ex erting downward ressure on the outside clamping member so as to force it ti htly against the frame A, and in the em odiment of my invention herein shown said means consists of a screw 12 mounted in the lug 8 on the member Dand adapted to be forced downwardlyinto engagement with the inwardly projecting arm on the key 3, the lug 8 being so arranged that the screw 12 willbearupon the arm 4 at a point intermediate the key 3 and the inner end of said arm. While I preferfto use the keys 3 for drawing the outside clamping members into operative position, I do not wish it to be understood that my invention is 'limited to a structure in which keys are used for, if desired, the outside clamping member could be provided with inwardly projecting arms being lon front ends of the s10ts'13 so as to 4*, as shown in Fig. 6-, for cooperating with the devices 10 and 12 carried-by the supporting members D. The caps C which are arranged over the joints between the ends of the outside-clamping members are pro- 'vided with inwardly projecting arms 4" supporting members there is not as great a liability of cracking or breaking the glass as there is in structures in which the clamping members are subjected to a direct pressure produced by the tightening of a bolt or screw. Another advantage of such a structure is that the outside clamping members are forced tightly against the glass and against the stationary frame in which the glass is arranged so that a tight joint is produced between said members and frame; and still another desirable feature is that the means which draws the outside.

clamping members into operative position and holds them in position is completely hidden from view. The inside glass-clamping member E which is arranged in engagement with the inner face of the glass rests upon the horizontally disposed flanges 7 of the stationary supporting members D, said members being so constructed that the inside clamping member E can be adjusted so as to accommodate plates of glass of different thickness. As 'shown in Fig. 3, the horizontal flange 7 of the member D is provided with inverted T-shaped slots 13 which'receives bolts 14 that project downwardly through openings in the inside clamping member E and having nuts 15 mounted on the lower ends thereof, said nuts lying in the The side wide portions of the slots 13. walls of the wide ortions of said slots prevent the nuts 15 om turning so that the inside clamping member E can be securely clamped to the supporting members D by insorting a screw-driver in the slotted heads of the bolts and turning same, the slots 13 enough to permit the bolts to move longltudinally thereof so as to pi'ovide for thick or thin plates of glass. If desired,

the members D can be provided with cover plates 16 which extend over the bottoms and revent displacement ofthe bolts 14 andit e nuts thereon.

Each of the keys 3 which are arranged inside of the outside clamping member C'is preferably provided with one or more forincense wardly projecting legs 3* that bear against the insideof said member C and thus hold the key in an upright-or substantially ver;- tical position and prevent it from tilting after it has been inserted in the member C. Said legs can be connected to the key in any suitable manner or,"if desired, thekey can be formed from a single piece of sheet metal pressed or drawn into the proper shape, as shown in Fig. 7, the legs 3 and arm 4: being integrally connected to the body port-ion of the key.
