OHN W. WATKINS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO DAVID LUP'IONS SONS COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A' CORPORATION OF PENNSYL- VANIA.

SHEET-METAL WINDOW-SASH.

To all whom it may concern:

Be it known that 'I, J OHN W. WATKINS, residing at No. 2223 East York street, in the city of Philadelphia,

unty of Philadelphia, and State of Pennsylvania, h ve invented certain new and useful Improvements in Sheet-Metal Window-Sashes, whereof the following isa specification, reference being had to the accompan ing drawings. I A

My invention relates to sheet metal window sashes and comprises such an organization of the sash that it may be reglazed without its dismemberment.

It comprises bounding members with continuous the sides of a series of panes, and intervening partitions between the adjacentmembersof said series. The bounding members are permanently united within the sash, whereas the intervening partitions are removably secured in position.

Italso comprehends removable means forfastening the end pane of a series in position, whereby, after said fastening means is removed, the end pane may be removed.

Said intervening partitions are provided at each .end with removable securing means, which may be unfastened, whereupon each intervening partition may be tilted to be removed after the pane in advance of it has been removed.

Although in its present embodiment my invention is shown as applied to a window in which the panes are mounted in vertical relation with one another, it will be readily understood that said invention is applicable to sashes inwhich the panes are mounted in horizontal relation with one another. 1

i In the accompanying drawings, Figure I, is an elevation oi a sheet metal casement window embodying my invention. Fig. II, is an elevation of a sheet metal pivot window also embodying my various improvements. Fig. III, is a section taken on the line III, III, in II. Fig. IV, is a section taken on the line IV, IV, in Fig. II. Fig. V, is a section taken on the line V, V, in Fig. II. Fig. VI,is a view similar to Fig. III, of a modified form of pane groove'and clamp.

In said figures:1, 1, are the side rails.

2, 2, are the bottom rails.

3-, 3, are the top rails. 4, 4, are the munnions, and 5, 5, are the muntins. The side, bottom, and top rails and the munnions may be termed bounding members while the elements (in this case muntins) which separate adjacent panes of v Said sash members are formed by interlocking pieces .of details of construction as are pertinent to my invention being shown'.

Referring to Fig. III, is formed by two strips of sheet metal having fiat portions 6, 6, forming the sides of the rails, together with the body portion of the rail 3, I

the moldings 9, 9, bent in the shape of an ogee curve, the metal at the lower end of this curve being then bent upwardly to form the sides 10, 10, of the pane groove, and then bent outwardly to form overhangs l1, 1]., at the proper height to correspond with the pane to be inserted in the window. The pane groove is closed by means of a plate or clamp 12, made of a piece of sheet metal formed by bending its edges downwardly and inwardly to fit over the overhangs 11, 11, and thereby keep the sides of the panegroove in position and prevent them i'rom spreading under the influence of heat. The plate or clamp 12, is usually made to extend over a portion of the distance between the pane supports. One of said clamps is shown indotted lines in Figs. I-and II. Its length is so proportioned to the width of the panes that it may be slid to one side to provide .room for the convenient withdrawal or insertion of a pane. The top of the rail is closed in the usual manner by the strip or cover 7. It will be understood that the outside configuration of this rail 3, may be varied to suit different conditions.

Referring to Fig. IV, which shows the mode of securing the muntins, or intervening partitions it will be seen that the muntins 5, are provided with longitudinal extensions or flaps 13, provided with holes 14, which are adapted to register with similar holes in the munnions 4. The muntins and niunnions are secured together by means of screws 15, passing through the holes 14. In Fig. I, the muntins are shown as fastened to side rails 1, 1, whereas, in Fig. II, the muntins are shown as fastened to side rails and munnions. These muntins bind the sash together to stop deflection by fire, yet are readily removable for reglazing the sash.

By employing the construction thus far described, it is possible to readily replace a broken panewithout dismemberment of the sash; for any pane in the top row is readily drawn up through the pane groove, and any intervening muntin, by the removal of the screws, may be slipped up and out of place, and thus the lower panes similarly removed. A, d W

Referring to Fig. V, the bottom rail 2, is of the usual construction except that at the top of the flat sides 16, there are short slots 17, adapted to receive tongues or flaps 18,extending from the flat faces of the munnions'4. These flaps are inserted through the slots 17, and bent upwardly against the inside of the top portion or molding of the rail body thereby securely holding the munnion to the rail. "At he inside of the munnion next to the pane groove are flaps 19, extending through the slots 20, at the bottom of the pane groove in the rail said shown to to m the oiiprhan s 21, 21, at the proper height III; but the pane groove and clampare slightly different. The lower ends oi the ogee curves 9, 9, are bent upwardly t form tlrle sides I0, 10, oi the pane groove andihen lent outwardly and 'downwardly as clearly to ooi'respo iid Willi-iii t le p die to be inserted in' the window The'panelgroove i dosed by means of a plate hr clamp 22, made of pi, ce of sheet lmetal formed by bendingitsredges downw rdly, inwardly and upwardly as shown by the portions 23, 24, and 25, to fit over the overhangs 21, 21,;and thereby keep the sides of the pane groove in position and prevent them from spreading under the influence of heat. Theclamp is provided with one or more flaps 27, which may be rasped by the fingers to move the cla mpalong the groove; it being understood that this clamp, like clamp 12, is usually made to extend over a portion of the distance between the pane supports.

In the description I have used the terms munnion and muntin, but in the claims I have found it convenient to use the term uniting member which it will be understood intended to mean either of them.

It is to be understood that I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.

I claim:

1. In a sheet metal window sash, the combination of a rail having portions bent to form the sides of a pane groove. said sides being provided with overhangs; and a sliding clamp uniting said overhang-s and preventing their separation under heat, said clamp having its length so proportioned to the' width of the panes of the sash as to permit of its being slid to one side to provide room for the withdrawal of the pane. v

2. In a sheet metal window sash, the combination with a rail having portions bent to form the sides of a pane groove, said sides being bent to form projecting overhangs and a sliding clamp engaging said overhangs for main taining the sides of said pane groove in position, said clamp having its length so proportioned to the width of the panes of the sash as to permit-of its being slid to one side to provide room for the withdrawal of a pane.

ii. In a sheet metal Window sash, the combination of a pair of bounding members for supporting the, sides of the series of panes;

and panes in succession for reglazing the sash without its disinemberment.

4. In a sheet metal window sash, the combination with a pair of members for supporting the sides of'the panes; of means for uniting said members rigidly in the sash; a muntins removably secured to said snpporting members and located between each of the panes; and removable means in the upper uniting member for clamping the upper pane groove, whereby said clamping means may first be removed and thenthe panes and removable niuntins in succession for reglazing the sash without its dismemberment. I

5. In a sheet metal window sash, the combination with a pair of vertical members provided with pane grooves. and rigidly secured to upper and lower uniting members also provided with pane grooves; of a series of panes separated by muntins removably SQCiIl'Qd to said vertical members; and a removable clamp for the pane groove in said upper uniting member, whereby upon removing said clamp the upper pane may be withdrawn through this groove: then by the removal of the securing means from the muntins, said muntins and the remaining panes may be removed successively without dismemberment of the sash.

6. In a sheet metal window sash, the combination of a pair of grooved supporting members adapted to receive a series of panes; a uniting member at the top and bottom of said supporting members and rigidL: secured thereto; a pane groove in the upper uniting member provided 'with a removable clamp for holding, the sides of the groove in said supporting members between each pair of panes,

whereby upon removing said clamp, the upper pane may be Withdrawn through the groovein the upper uniting member, and by removing the securing means from the muntins said mnntins and the ramaining panes may he'removed successively for reglazing' without dismemberment of the sash.

In testimony whereof, I have hereunto signed my name, at Philadelphia, Pennsylvania, this 28th day of December, 1906.

, I JOHN W. WATKINS.
