I I HHH H r/WM l l/ All? United? States Patent 2,888,721 WINDOW Andrew T. Hagerty, Elkhart, Ind., assignor to The \dlake Company, Elkhart, Ind., a corporation of Illinois Application July 20, 1956, Serial No. 599,119 Claims. (Cl. 20-69) This invention has to do with windows of the type in which a sash is pivotally mounted in a frame and sealed in its closed position by a continuous sealing gasket located between the outer periphery of the sash and the inner periphery of the frame.

It is a general object of the invention to provide in a window of the type described new and improved sealing or gasketing means between the sash and the frame in the form of a continuous strip member having a base section adapted to be frictionally retained in a peripheral recess in the sash and a compressible or distortable tubular section which is adapted to project across the clearance space between the sash and the frame.

It is a more specific object of the invention to provide in a window of the type described a new and improved sealing gasket comprising a metal base or holder strip which is bent upon itself and which clamps between the flange forming legs thereof the marginal edges of a reversely folded strip of fabric covered rubber sheeting, with the latter projecting therefrom in the form of a tube and being adapted to span the space between the sash and the frame and resiliently engage with the inward 1y facing surface of the frame thereby to provide a weather seal between the sash and the frame.

It is another object of the invention to provide a sash and a sealing gasket of the character referred to wherein the sealing gasket is characterized by being divided into annular corner sections and connecting strip sections which are individually insertable in the edge recess provided in the sash and frictionally retained therein whereby to facilitate initial assembly of the gasket and the sash and subsequent replacement of the gasket when required.

These and other objects and advantages of the invention will be apparent from a consideration of the window construction which is shown by way of illustration in the accompanying drawings wherein:

Figure 1 is a perspective view of a window constructed in accordance with the invention, the sash being shown in open or angular relation relative to the frame;

Figure 2 is a partial elevation, to an enlarged scale, of the lower portion of the window with the sash in closed position relative to the frame;

Figure 3 is a section taken through the connecting pivot between the sash and the frame on the line indicated at 33 in Figure 2, to an enlarged scale;

Figure 4 is a fragmentary view, on a still larger scale and with portions broken away, showing the details of a corner of the sash and the associated sealing gasket;

Figure 5 is an exploded view, on an enlarged scale, showing in elevation a corner portion of the sash with portions of the sealing gasket in position for insertion in the edge recess in the sash;

Figure 6 is a section, on a larger scale, taken on the line 6-6 of Figure 5; and

Figure 7 is a perspective view, on an enlarged scale, of a portion of the sealing gasket.

Referring to the drawings, the window includes an 'ice outer stationary frame 10 of generally rectangular form, which frame is adapted to be anchored and sealed any suitable manner in an opening in the wall of the building. The frame 10 surrounds and fits closely about a glazed sash 11 of the same general rectangular form. The rail members 12 of the frame 10 and the rail mem bers 13 of the sash 11 are both preferably constructed of extruded aluminum but either or both may be cori-- structed of any other suitable material. I

The sash 11 is pivotally connected, preferably midway between its sides, to the frame 10, the pivotal connection being effected by aligned top and bottom pivot pins 14 and 15. The sash 11 is provided about its outer periphery with a pair of laterally spaced, continuous, outwardly opening groove or recess formations 16, preferably of generally rectangular cross section, in which a continuous sealing member 17 is partially housed. The continuous recesses of slots 16 open outwardly of the edge face 18 of the sash rails 13 and are in confronting relation with the inwardly facing periphery 19 of the frame 10. The recesses 16 are spaced laterally so that they are 10- cated near the outer edges or faces of the sash rails 13 on opposite sides of the supporting pins 14 and 15 which are located in the center or intermediate the side edges of the same.

The pins 14 and 15 are mounted in a similar manner being secured in a sleeve 20 (Figure 3) in the bottom sash rail 13 and projecting into the bearing sleeve 21 in the bottom rail 12 of the frame 10. The sleeves 20 and 21 have confronting flange or

shoulder formations

22 and 23 which project slightly from the faces of their respective rails and hold the sash 10 in spaced relation within the frame 11.

The Weatherstrip or sealing member 17 is of special construction and is arranged to provide a continuous seal extending between the confronting faces 18 and 19 of the sash 11 and the frame 10. The sealing member 17 comprises a holder member or base section 24 and a resilient compressible tubular member or section 25 projecting therefrom. The tubular section 25 is preferably formed from a napped cloth sheeting vulcanized to a relatively thin base sheet of rubber. The holder member 24 is preferably formed initially from a relatively narrow fiat strip of relatively thin metal such as aluminum sheeting or the like. In fabricating the sealing member 17, a relatively narrow metal strip is folded on its longitudinal axis to provide a channel of generally U- shaped cross section while a strip of napped rubber sheeting is folded on its longitudinal axis to form the tubular section 25 adjacent or along the fold and marginal portions or flanges 26 which are brought together into flatwise relation and engaged between the legs 27 of the folded aluminum strip member or holder 24 as shown in Figure 7. The leg portions of the strip member 24 are creased somewhat at 28 adjacent the fold area which results in a slight outward bowing or bulging of the marginal portions permitting these portions to be resiliently compressed when the member is inserted in the recess 16 so that the member is resiliently held in position in the recess. The tube forming portion or section projects from the holder 24 so that when the weatherstrip member 17 is attached to the rails 13 of the sash 11 by seating the holder member 24 in the recess 16, the tubular section 25 projects into the space between the confronting faces 18 and 19 of the sash 11 and frame 10 providing an allweather seal between the same and bridging the space separating the two members.

In preparing the sealing member 17 for assembly in the grooves or recesses 16 in the sash rails 13 corner pieces or members 29 are provided as shown in Figure 5, which are formed by abutting the mitered ends of two relatively short sections 30 of the assembled sealing strip material as at 31 and vulcanizing the abutting edges of the gasket forming tubular section 25, as indicated at 32. The other ends of the sections 30 are cut on transverse lines except for the ends of the tubular section 25 which are cut on a diagonal 'line, as shown at 33, providing an end portion adapted to be tucked into the corresponding tubular section 'of an adjoining straight length 34 of the sealing member 17 which extends in the recess 16 between the corner members 29. With this arrangement, the assembly of the sealing member 17 with the sash frame to provide an unbroken or continuous seal is readily accomplished even after the sash 11 is installed in the frame 10. The leg portions 27 of the weatherseal holder member 24 have sufficient resiliency to normally hold the strip members in resilient engagement within the groove 16 so that the tubular section 25 thereof'projects between the confronting faces 18 and 19 is distorted or compressed somewhat when the sash 11 is in the closed condition as illustrated in Figure 3.

While specific details of construction and specific materials have been referred to in describing the illustrated form of the invention, it will be understood that other details of construction and other materials may be resorted to within the spirit of the invention.
