Renewed May 23, 1935 9 Glaimst (01. 189-72) This invention relates to window construction,

an object ofthe invention being to provide a win dow construction having sliding sashes, the latter having roller contact with the frame, said contact being adjustable so as to ensure an easy movement and yet provide a tight sash.

A further object is to provide, in combination with the roller sash, improved resilient weather strips with which the sashes contact.

A further object is to provide an improved frame construction with a removable section providing access to the weight boxes.

A further object is to provide a window construction having an improved arrangement of parting strip and inner bead, both of which are removable to facilitate the assemblage of the sashes in the frame or'r'emoval of the sash there provided at its bottom or lower end with angular anchor pieces for fastening the sill to the channel frame, and the upper corners of the channel.

frame are riveted or welded together and create an'unusual, strong construction upon which masonry may lie and serve instead of a lintel.

A further object is to provide a window construction of this character embodying many novelfeatures of construction and combinations and arrangement of parts, all of which will be more fully hereinafter described and pointed out in the claims.

Figure 4 is a view in elevation of one of the the removable section to provide entrance to the weight box;

Figure 8 is a fragmentary plan vievv of the upper sash; and

Figure 9 is a fragmentary sectional plan view of the lower sash.

Our improved window construction embodies a heavy gauge channel-shaped buck illustrated generally'by the reference character I, which is located around three sides of the window opening; that is to say, at the top and at both sides of the opening. This buck constitutes weight boxes and spaces for the necessary pulleys and the like for supporting the sashes, and may be of steel or other metal. The lower ends of the buck receive therein anchor pieces 3, the latter'having upright flanges 4 to which in-turned flanges 8 on the buck are secured. These flanges 8 are preferably turned backward on themselves for strength and for rigidity of coupling. Non-ferrous frame members 5; are secured to the anchor pieces 3 and close the open portions of the channel-shaped buck l. The anchor pieces 3 also serve to secure the buck and frameto a sill I so that the buck, sill and frame members constitute a strong, rigid structure which may be inserted in the window opening. The side members of the buck l which form weight boxes have removable and swinging partitions 9 therein which are hung from the top and which can be readily moved so that access may be had to both compartments through a single entrance, as will more fully hereinafter appear. An upper member ll) is also fixed to the upright side members 5 and to the lintel portion of the buck to complete the frame structure, and plates ll located at proper intervals are secured to the weight boxes and lintel formed by the buck l and to the masonry or wall construction.

The vertical side members 5 of the frame are made with integral outer beads l2 comprising an inverted three-sided channel shaped member and with seats for a removable inner bead l3 and a removable parting strip it. The parting stripl t has a plate It extending throughout the length of the frame, forming with the strip Mi a member T-shaped in cross section, each end of the T head it comprising a bearing surface having sealing engagement with the upper and lower sashes A and B. The strip It has flanges it at its edges which co-operate with shoulders H which form the parting strip recess on the frame member and on a removable section it of the frame, to form holding means or confining means for the edges of bowed Weather-strips i9 located at opposite sides of theparting strip. The weather strips I 9 are integral parts. of an element U-shaped in cross section. The*bottom of the U-shaped element fits between and isheld by the shoulders I! and the legs of the U-shaped element project outward from the Jamb member. The parting strip l4 may be removably secured in place by means of screws 20 so that it may be strip "properly engaging over an enlargement readily removed as occasion may require. The strip I 4 cooperates with the shoulders llto hold the weather-strip element in place.

The inner bead II. constitutes a bar which has webs 2| fitting in grooves 22 in the frame member '5 and in the removable section l5 respectively, and this inner bead I 3 issecured to the frame member 5 by means of screws 23 so that it is readily removable on occasions. The removable section II of the frame member 5, which may be punched directly out of the frame member and preferably extends for but a short distance of the length of the frame member, is held in closed position by one of the webs 2! of the inner bead l3, and also by reason of the fact that this section I! has a stepped plate 24 fixed to its rear face which extends back of the strip l4, and screws 20 which hold the parting strip l4 in place are also screwed into threaded openings 25 in this plate 24 after being screwed to the frame bar 5.

Aand B represent the upper and lower sashes which are .mounted to slide in the frame between the beads i2 and i3 and the parting strip l4. The upper horizontal bar 25 of the sash A has agrooved portion 21 receiving a web 28 on the bar I5, and the lower bar '25 of the lower sash B is provided with webs 30 and II and a weather- 33 on the sill I. Meeting rail 34 of the upper sash A and meeting rail35 of the lower sash B are formed with inter-engaging webs 36 and 31. The rail 34, carries a weather strip 38 engaging the web 31, and a flange or web on the-bar 35 engages the upper edge 01'- the bar 34 giving a three-point contact. The construction of the three-point contacts between the bars of the sash and frame are illustrated in our United StatesPatent No. 2,084,355, dated June 23, 1937.

An important feature of this invention is the employment of rollers 40 which are carried by the vertical-bars of both sashes which engage the outer bead l2, and by reason of the adjust ment of these rollers the frictional sealing engagement between the webs 4l'on the rails and the resilient weather-strips I9 is regulated. Any desired number of these rollers 40 may be em-.

ployed, and each roller 40 issupported on a trunnion 42 projecting from the end of a plate 43, and the major portion of the roller is housed within the hollow vertical bars of the sash frames. The ends of the plates 43 are movably fulcrumed in notches 44 in the sash bars 45. The trunnions 42 move in slots 45 in the peripheral walls of the bars 45, and the rollers 40 project through slots 41 in the inner side walls ofthe bar and bear against the beads l2 and II respectively. Screws 45 project through the openings 49in the bar 55 and have screw-threaded engagement with the plates 42 so that by adjusting these screws the angular disposition of the plates may be varied so as to force the rollers with variable pressure against the,beads. The pressure exerted forces the web 4i, on the opposite side of the vertical sash'bars from which the rollers 40 project, into sealing frictional engagement with.

surfaces at either side of the T head l5- to give a weather-tight and freely movable -engagement between the sashes and the parts of the frame;

' Should it be necessary at any time to have access to the weight boxes the inner bead I2 and the parting strip l4must be removed, which will release, the movable section is and allow it to be removed. When this section is in place the inner bead and parting strip may be replaced and the 4 and frame together provide spaces between them,

vminimum frictional engagement.

constituting air pockets or cushions which resist wind pressure. While there is a weather-tight juncture between the sash and frame there is a This reduction of frictional contact is due primarily to the fact that the sashes have at their outside edges F rounded beads 4a which ,are adapted during the sliding movement of the sashes to contact with the frame; thus the entire edges of the sash do not at any time contact with the frame.

Particular attention is called to the manner of securing the panes of glass 53 in the sashes. A groove 54 may be provided in one bar of the sash to receive a pane of glass, the other three bars of the sash being formed with integral flanges 55, between which and removable glazing anchor strips 55 the glass' is secured. These glazing anchor strips 55 are secured by screws 51 to the sash bars and lie back of integral flanges '58 on the sash bars so that wind pressure is sussashes .A and B at the overlapping portions of, their meeting rails have notches 5|! at the ends of the meeting rails and these notched portions- Qf the sashes receive the parting strip I4. 0n the parting strip a plate 5| is secured. This plate, shown in Figure 2, .is relatively short and v has bevelled or inclined ends 52' so that when the sashes are together the'plate 5| will bear tightly against the ends of the sashes'and hold them against rattling or movement. When'the" sashes are partly opened they will, be free from contact with the plate. 5i and can slide readily in the frame without unduefriction.

By reason of the construction above described, it will be noted'that we not only employ a novel arrangement of buck, non-ferrous jamb, header and sill so constructed as to receive the sliding sashes, but we also provide a novel arrangement of parting strip with continuous resilient weatherstrips therein which are housed in the parting strip, and the specially designed frame construction provides flat riding surfaces for the rollers of the sashes to provide easy operating movement thereof.

While we have illustrated what we believe to be the preferred embodiment of our invention, it is to be distinctly understood that various slight changes may be made with regard to the form and arrangement of parts without departing from our invention, and hence we do not-limit ourselves to the precise details set forth but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scone of the claims. 7
