ALBERT H. SISSON, OF ST. LOUIS, MISSOURI, ASSIGNOR TO ST. LOUIS OAR COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION.

METAL WINDOW-SASH.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed November 15. 1906. Serial No. 343.493. Renewed July 22. 1907. Serial No. 38 L918- and stiles, connecting corner blocks seated within the stiles and rails, and means in the form of bolts whereby portions of the rails and stiles are drawn into the connecting blocks to bind the parts to each other.

Figure I is an elevation of one corner of my metal sash. Fig. II is a cross section taken on line III I, Fig. I. Fig. III is a cross section taken on line IIIIII, Fig. I. Fig. IV is a cross section of a modification. Fig. V is a cross section of another modification. 1 designates one of the sheet metal stiles of my metal window sash (see Figs. I and III) which are of approximately U-shape in cross section and the wings of which are bent inwardly toward each other at 2 and .U-shape in cross section, the wings of these rails being bent inwardly toward each other at 5 and terminating in clamping arms 6.

7 are connecting blocks, preferably of cored form to render them of lighter weight. Each of the connecting blocks preferably consists of a single casting and is provided at its sides with recesses 8. Extending through each block in line with the recesses in the sides thereof are bolt holes 9. The connecting blocks are reduced in thickness at their inner portions against which the clamping arms of the sheet metal stiles and rails bear when the parts of the sash are united.

10 are binding bolts that are passed through bolt holes in the stiles and rails of the sash and the bolt holes 9 in the connecting blocks, each bolt being provided with a nut 11. The connecting blocks are introduced into ends of mating sash stiles and rails that are to abut against each other when the members of the sash are assembled, and upon the parts being brought to their proper positions relative to each other the bolt holes in the stiles and rails register with the bolt holes in the connecting blocks and the recesses also in said blocks at the locations of the bolt holes.

A suitable die or punch is then utilized to indent portions of the wings of the stiles and rails into the recesses in the connecting blocks, as seen in Figs. I and II, whereby said wings are embedded into the connecting blocks for holding action. The bindin bolts are then inserted through the bolt holes in the stiles, rails and connecting blocks and the nuts of said bolts are applied to them with the result of firmly uniting all of the parts to each other. Rivets, however, ma be used in lieu of the bolts and headed after they are passed through the holes that re ceive them.

12 designates channeled cushion strips of elastic material such as rubber and which are adapted to receive the pane of glass A that is mounted in the sash. These cushion strips are seated at their bases between the clamping arms 3 and 6 ofthe sash stiles and rails respectively, and held in place in part by said arms.

13 are clamping face strips that are fitted to the clamping arms of the stiles and rails and bear against the cushion strips, as seen most clearly in Figs. II and III, for holding action upon said strips. These clamping strips are connected by binding screws 14 that pass through them at intervals and through the connecting blocks 7 at the locations of said blocks. Intermediate of the connecting blocks the binding screws extend through distance sleeves 15 that are positioned between the clamping arms of the sash stiles and rail wings (see Fig. III). 7

In the modification shown in Fig. IV the bottom rail 4 of the sash is preferably formed of two pieces of sheet metal, one of which extends laterally at its lower end and then downwardly and the other of which is flanged around the termination of the first named, and connected thereto by rivets as seen at 4*. By this construction an extension is formed at the bottom of the bottom rail which is adapted to fit against the side face of the rest on which the sash is supported when in an elevated position, as indicated in dotted lines, in order that the sash may be held from escape from said rest.

In the modification shown in Fig. V, the sash stiles and rails 1 respectively, are provided with straight wings instead of being formed with the clamping arms previously described and the elastic cushion strips 12* are seated directly in the stiles and rails and clamped therein by binding screws 14 that extend through the stile and rail wings and the cushion strips.

The sash herein described is more particularly intended for use in windows of street railway or other cars, but may be used in windows in other structures.

I claim 2- 1. A metal window sash consisting of stiles and rails of U-shape in cross section, connecting blocks seated in said stiles and rails and having recesses in their sides adapted to receive portions of said stiles and rails, and means for uniting said stiles and rails to said blocks, substantially as set forth.

2. A metal window sash consisting of stiles and rails of U-shape in cross section, connecting blocks seated in said stiles and rails and having recesses in their sides adapted to receive portions of said stiles and rails, and binding bolts extending through said stiles and rails and said connecting blocks, substantially as set forth.

3. In a metal window sash, the combination of stiles and rails of U-shape in cross section, connecting blocks seated in said stiles and rails and having recesses in their sides and bolt holes extending therethrough in line with said recesses, said recesses being adapted to receive portions of said stiles and rails, and binding bolts extending through said stiles and rails and said connecting blocks; said binding bolts being each provided at one end with a head and having a nut at the other end adapted to bear against indented portions of the stiles and rails at opposite sides of said connecting blocks, substantially as set forth.

4. In a metal window sash, the combination of sheet metal stiles and rails of U-shape in cross section, the wings of which terminate at their inner ends in clamping arms, cushion strips seated between said clamping arms,

and means for binding said arms to said cushion strips, substantially as set forth.

5. In a metal window sash, the combination of sheet metal stiles and rails of U-shape in cross section, the wings of which terminate at their inner ends in clamping arms, cushion strips seated between said clamping arms, clamping strips seated against said clamping arms and against said cushion strips, and means for connecting said clamping strips to each other, substantially as set forth.

6. In a metal Window sash, the combination of sheet metal stiles and rails of Ushape in cross section, the Wings of which terminate at their inner ends in clamping arms, cushion strips seated between said clamping arms,

clamping strips seated against said clamping arms and against said cushion strips, and binding screws connecting said clamping strips, substantially as set forth.

7. In a metal window sash, the combination of sheet metal stiles and rails of U-shape in cross section, cushion strips located between the wings of said stiles and rails, distance members located between the wings of said stiles and rails, and clamping means connecting said wings, substantially as set forth.
