STORE-FRONT AND SHOW-WINDOW.

Specification of Letters IPatent. Patented Nov, 141 1911,

Application filed January 24, 1911. Serial No. 664,389.

comprise outside clamping members thatbear against the glass and also against the stationary frame in which the glass is arranged.

One object of my present invention is to provide a structure in which the means that retains the outside clamping member in position can be manufactured cheaply and installed easily.

Another object is to provide a structure of the character described that comprises means of novel construction for retaining the adjustable inside glass-clamping member in position. And another object is to provide a key of novel construction for retaining the outside clamping member in position.

Other objects and desirable features of my invention will be hereinafter pointed out.

4. is a vertical sectional view taken on the line 4.-4 of Fig. 1; Fig. 5 is a horizontal sectional view taken on the line 5-5 of Fig. 2 looking in the direction indicated by the arrow in Fig. 2; Fig. 6 is a vertical sectional-view similar to Fig. 3 of a slightly modified form of my invention; Fig. 7 is a perspective view of one of the supporting devices shown in Figs. 1 to 4 on which the inside glass-clamping member rests; and Fig. 8 is a perspective View of the key shown in Fig, 3.

Referring to the drawings which illustrate the preferred form of my invention, A designates the sill or lower cross-piece of a stationary frame in which a plate of glass B is arranged, and 1 designates blocks or other suitable devices on which the lower edge of said plate rests. An outside clamping member C is arranged in engagement with the outer face of the glass and in engagement with the sheet metal covering 2 that extends over the lower cross-piece A of the frame, and suitable means is provided for retaining said member C in position and drawing it inwardly toward the glass and downwardly toward the frame A. The outside clamping member C may be of any preferred shape or construction but I prefer to form said member from a piece of sheet metal molding provided with vertically disposed flanges 1 and 2" that cooperate with the means which retains said member in position. Said retaining means preferably consists of keys 3 arranged inside of'the member C in engagement with the flanges 1 and 2*, as shown in Fig. 3, and provided with arms 4 that project inwardly beyond the glass, and adjustable devices 5 arranged on the inside of the opening which the glass closes for engaging the arms 4 so as to exert inward and downward pressure on same.

In the embodiment of my invention herein shown, the arm 4 of each key is deflected downwardly and thence upwardly, as shown in Fig. 3, so as to produce an inclined surface 4 on which the lower end of one of the devices 5' bears, and at the inner end of the arm 4 is a depending L-shaped leg 4. which rests upon the top face of the lower cross-piece A of the glass-supporting frame or rather upon the sheet metal covering 2 on said cross-piece if said cross-piece is provided with a cover as herein shown. This leg 4 supports the inner end of the arm 4 so that when the device 5 is screwed down wardly the tapered lower end 5" of said device will bear against the inclined surface 4: of the arm and thus cause the key 3 to draw the outside clamping member C inwardly and downwardly, the pressure which the device 5 exerts on the arm i also operating to cause the 1e 4 to clamp the sheet metal covering 2 tig tly against the lower cross-piece A of the glass-supportin frame. If desired, the key 3 can be provi ed with a forwardly projecting part 3 that bears against the inner side of the member 0' and thus retains said key in an upright position. By forming the key in this manner, namely, providing it with a depending lug or other' suitable supporting device at its lnner end I overcome the necessity of forming a suporting leg on the member which carries the evices 5.

While I have herein shown only the outside clamping member that is arranged adjacent the lower edge of the glass and have used-the terms inwardl and .downwardly to indicate the dlrection in which said clamping member is moved, it will, of course, be understood that outside clamping members are arranged at the sides and uper edge of the glass, and that said memliars are moved into engagement with the glass and with the glass-supporting frame when the devices 5 which cotiperate with said members are adjusted. 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 lower cross-piece of the glass-supporting frame.

The devices 5 are mounted on a continuous member 6 that runs longitudinally of the lower edge of the glass, said member 6 preferably consisting of a piece of angle iron arranged with its vertical leg in engagement with the lower cross-piece A of the frame and its horizontal leg projecting outwardly from the upper edge of the vertical leg, as shown in Fig. 3. Screws 7, or other suitable fastenin devices, pass through the vertical leg 0 the member 6 and secure it-to the frame A, and the horizontal leg of said member is provided with screw-threaded holes in which the devices 5 are adjustably mounted.

An inside clamping member D is arranged on the inner side of the glass, and a plurality of shiftable devices are mounted on the member 6 for carrying said clamping member D and holding it in'adjusted position, thereby enabling the member D to be adj usted relatively to the member C so as to accommodate glass of different thickness.

Each of the shiftable devices herein shown for supporting the inside clamping member D and retaining it in position consists of a substantially channel-shaped spacing device 8 provided with a block 9 that is arranged in an elongated'slot 10 in the horizontal flange of the member 6, and a screw 11 that passes through said clamping member and projects into a screw-threaded opening in the block 9, as shown clearly in Figs. 2 and 4. The block 9 .is provided at its lower end with a head 9 which bears against theunder side of the horizontal flange of the member 6, and the spacing de-'- vice 8 is connected to said block 9 in such a manner that the block can move upwardly relatively to the spacing device and thus bring the head 9 on said block tightly against the member 6 when the screw 11 is tightened. The block 9 passes loosely through a hole 8 in the spacing device 8 .and the upper end of said block is flanged loosened. By loosening the screws 11 the inside glass-clamping member D can be moved easily toward or away from the glass, because when said screws are loosened the blocks will drop downwardly far enough to carry theheads thereon out of engagement with the member 6. After the inside clamping member has been adjusted in proper position the screws ll'are tightened so as to press the spacin devices 8 downwardly against the top ace of the horizontal flange of the member 6 and also draw the heads 9 on the blocks 9 tightly against the bottom face of the horizontal flange of the member 6. A means of the" construction above described for retaining the inside glass-clamping member in position enables said member to be adjusted quickly and easily, it retains said member securely in position, and it can be assembled complete by the manufacturer and ship ed to the point where it is tobe installed, t us eliminating a great deal of time and labor in the operation of setting up the device. The keys 3 which retain the outside clamping member 0 in position, are also an improvement on the keys which have heretofore been used in structuresof this type because they are so constructed that it is not necessary to provide the member 6 with lugs or supporting devices for the inner end of the arms on the keys. Consequently, I am able to use a piece of angle iron to form the member 6 instead of castings of special construction. The keys 3 are preferably in one piece and are formed" of ressed or stamped sheet metal but they could, of course, be formed in various other ways.

While I prefer to provide the arm 4 of each key with an inclined surface 4 against which the pointed end of the device 5 bears so as to draw the outside clamping member downwardly and inwardly when the devices 5 are tightened, I do not wish it to be understood that this is the only kind of key that can be used for, if desired, the key can be provided with an inwardly projecting straight arm 40, as shown in Fi 6, having teeth or corrugations 40" forme in the top face thereof to cooperate with the pointed end of the device 5. When keys of this construction are used, one of the workmen who is installing the device, presses the outside clamping member C inwardly and downwardly and then the workman who is on the other side of the glass, tightens the screws 5 so as to exert downward and inward pressure on the arm of the key and thus securely lock the outside clamping member in position.
