WEATHER-STRIBPED METAL WINDOW.

Application filed April 11, 1927. Serial No. 182,561.

This invention relates principally to metal windows equipped with sashes Slidable 1n guide slots provided therefor in the hollow jainbs of the window frame, and 1t relates more particularly to the application of metal weatherstrips to said windows.

The principal object of the present invention is to provide simple and eflicient weathcrstripping, which will prevent air and dust from entering the room through the joints and slotted jamb members of the above type of metal window and which can be easily and cheaply applied without any alterat1on of the frame or sashes. Other objects are to prevent rattling ofthe sashes without interfering with the easy movement thereof and to maintainv a weatherproof construction in all positions of the sliding sashes,

rlhe invention consists principally in the novel construction, arrangement and application of weatherstripping; and it also consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanyin drawings, which form part of this speci cation and wherein like symbols refer to like parts wherever` they occur,

Fig. 1 is a vertical cross section through a metal window construction equipped with metal weatherstripping embodying my invention;

Fig. 2 is a horizontal section through one side of the window frame and the adjacent portion of the upper sash on-the line 2 2 in Fig. l; andv v Fig. 3 is a similar cross section through one of the jambs of the window casing and the ,adjacent side rail of the lower sash on the line 3-3 in Fig. l. v

In the accompanying drawings, my invention is illustrated in connection with a metal window of the double-hung sliding-sash type, said window comprising a metal window frame or casing member A arranged for vertically sliding upper and lower metal closure members or sashes B and C', respectively. The metal window frame or casing A shown in the drawings comprises a hollow head or lintel box 4, a sill 5, and two' hollow or tubular .jarnbs 6, one only of which is shown. As shown in the drawings, the parts of the hollow jambs 6 are arranged to form enclosed boxes for the sash wei hts and chains (notshown) and the opposing inner walls of the hollow jambs are each provided with two vertical guide slots 7 and 8, which extend from head to sill of the window frame or casing and constitute slideways for the upper and lower sashes, respectively.

The upper and lower sashes comprise main frame members 9, which, are offset to form rabbets for supporting the mar nal edges of the sash panes 10, and retaining strips 1l secured to said main frame members to hold said panes therein.

As shown inthe drawings, the vertical frame members, which form the side rails of the upper or outer sash B, have their outer flanges 92L slidably arranged in the outer guide slots 7 provided in the innervor opposing walls ofthe hollow jambs 6. The upper flange 91 of the main frame member, which forms the top rail of the said sash, projects within a downwardly opening slot or groove 4a in the bottom of the lintel box 4 in the closed position of the sash; and the retaining strip which cooperates with said main frame member is provided with a stop shoulder 1la adapted to abut against the under side of the lintel box in the closed position of said sash. The retaining strip on the lower or meeting rail of the upper sash is preferably vprovlded along its lower inner edge with an upstanding hook flange 11",.

The vertical frame members, which form the side rails of the lower or inner sash .0, have outstanding vertical side fianges 9 slidably arranged in the vertical slots or slideways 8 provided therefor in the opposing faces of the hollow jamb members 6 The retaining member on the upper or meeting rail edge of the lower sash C is shown provided along its upper outer edge with a depending hook flange ,11 adapted to overlap the upstanding hook flange 11"A of the lower or meeting rail of the upper sash B in the closed positions of said sashes. As shown in the drawings, blocks 6 are secured to the'inner faces of the hollow jambs 6, between the guide slots 7 and 8 thereof, in

osition to close the joints between said jambs and the ends of the meeting rails of the sashes in the closed positions thereof. The framing member, which forms the bottom rail of the lower sash C, is arranged with its bottom flange 9d in position to cooperate with the sloping outer side of an upstanding rib 5l on the sill member 5 of the window frame A; and retaining strip for said bottom rail of said lower sash C has an outstanding flange 11d, which terminates in a depending lip adapted, in the closed position of said sash, to seat within an upwardly opening groove or channel 5b provided therefor in the stool portion of said sill.

In order to prevent air and dust from entering the building through the guide slots 7 and 8 in the hollow jamb member 6 of the window, sad jamb members are provided with metal weatherstrips 12, 13 and 14. As shown in the drawings, the weatherstrips 12 preferably extend from the sill 5 to the lower edges of the filler blocks 6a 'and are adapted to completely close the lower, normally unoccupied, portions of the guide slots 7 for the upper sash B. The weatherstrips 13 extend from the upper ends of the strips 12 to the underside of the lintel box 4 and serve to weatherproof the joint between theupper portion of the outer guide slot 7 and the guide or runner flanges 9a of the upper sash B in the closed, position thereof. The strips 14 are secured to the jamb members 6 adjacent to the outer face of the lower sash C and extend from the sill 5 to the under side of the filler blocks 6 and serve to Weatherproof the joints between the lower portion of the inner guide slots 8 and the runner or guide flanges 9c of the lower sash C in the closed position thereof. By this arrangement, the strips 12 and 13 serve to prevent air and dust from entering the hollow j ambs 6 through the guide .slots 7 for the upper sash B; and the strips 14 serve to prevent air and dust from entering the building through thejoints between the v:its

lower sash C and the portion of the guide slots 8 normally occupied thereby.

Each of the weatherstrips 12 is provided along its middle portion with a. longitudinal channel 12, which snugly fits the lower, normally unoccupied, portion of theouter guide slot 7, and outstanding side marginal flanges 12", which bear against the jamb 6 on opposite sides of said outer guide slot. As shown in the drawings, the channel 12?1 is' of a width adapted to accommodate the runner or guide flanges 9a of the upper sash B when the same is lowered; and the side marginal flanges 12b of said strip are preferably provided with corrugations 12c where they join the side walls of the channel 12a to prevent binding or cutting of the strip on the sides of the slot. As shown in the drawing, the side flanges of the strip 12 are provided adjacent to the corrugations 12c with reverscly cor rugated portions 12d adaptedto bear against the j amb; vand the free marglnal edge of the ,Y

outer flange of said strip is provided with a hollow bead 12e, the corrugations 12c and 12d and the bead 12e permitting the flanges of the strip to be clamped tightly against the jamb to secure a weatherproof joint between the jamb and the strip.

Each of the metal weatherstrips 13 preferably comprises a metal strip of substantially angular cross-section, one flange 13 of which is rigidly secured to the jamb; and the other flange 13b extends in to the outer guide slot 7 and constitutes a resilient sealing member which bears against the adjacent face of the guide flanges 9a'of theupper sash in the closed position thereof and thus serves to weatherproof v the joint between said flange and saidr slot. The flange'13a of the strip 13 is longitudinally corrugated as at 13C, where it joins the resilient sealing flange 13, -thereby preventing binding or cutting of the strip on the edge of the slot. The flange 13a is also provided adjacent to the corrugation 13c with a reversely corrugated portion 13d, and has a curled marginal edge.

the guide flanges 9c of the lower sash C and l the portion of the guide slots l8 normally occupied thereby are secured to the jambs 6 adjacent to the outer face of said sash. Each of the strips 14 is of angular cross-section, one flange 14a being secured to the jamb, and the otherflange 14b being-.left free and extending into the guide slo/t 8 in position to resiliently engage the guide flange 9 of thelower sash. ings, the flange 14a, Ywhich is secured to the jamb, is reversely corrugated, as at 140,'to secure a tight joint between said flange and the jamb and to prevent cutting or binding As shown in the draw-- of the resilient Sealing flange 14b on the edge of the guide slot 8. 4

The outer marginal flange 12a of a'strip 12 is secured to a jamb 6 preferably by means of a rigid clamping bar or strip 15 that is held in position by means of screws 16, which pass' through said flange and said clamping bar and are threaded into the jamb'. Thel clamping bar or strip 15 has the same crosssectional shape as the flange engaged there' by. The corrugated inner marginal flange 12a of a strip 12 and the corrugated flange 14aI of a strip 14 are rigidly clamped to a jamb by means of a rigid.l clamping bar or strip 17, which is secured Ato said jamb by screws 17a, and has its side marginal portions` serve valso as guard or wear plates to revent i the thin gage weather-strips engage thereby from being crushed or otherwise dam aged.

The joint between the top rail ofx the upper sash B and the guide slots occupied` thereby in the raised position of 'saidssh is les weatherproofed preferably by means of a strip 2O of substantially the same cross-sectional shape as jamb strips 13, and is secured in position by means of a clamping strip 21 similar to the clamping bar 18 used to secure the strip 13 in place. i

The oint between the meeting rails of the upper and lower sashes is weatherproofed preferably by means of a metal weatherstrip 22 secured to the hook flange 11b of the meeting rail of the upper sash B. As shown in the drawing, said strip comprises a main body portion of angle shape section provided with a rebent resilient sealing flange 22a adapted to bear against the'depending hook flange 11c on the meeting rail of the lower sash C in the closed position of the two sashes.

The weatherstrip 23 for the joint between the bottom rail of the lower sash C and the sill 5 of the window frame 'A' comprises av strip of metal secured along one'edge to the top of the upstanding rib' 5a ot' said sill 5 and a downwardly extending resilient free marginal portion adapted to be engaged by the lower flange 9d of the bottom rail of the lower sash in its closed position.

The arrangement hereinbeforc described has numerous advantages. It minimizes the time and expense of applying t-he strips by eliminating the need for altering the sashes or frame and by enabling the strips to be readily applied with a minimum number of fasteners. It prevents rattling of the sashes without interferring with the easy movement thereof; and it remains weatherproof and dust-proof in all positions of movement of the sashes and when the sashes are frame expand or contract due to temperature changes.

Obviously, the construction hereinbefore described admits of considerable modification without departing from the invention; therefore, I do not wish to be limited to the precise arrangement shown and described.
