This invention relates to weather stripping for slidin window sash, the purpose bein to provi e weather stripping that 1s mounted upon the sash and in engagement with the frame in which the sashlis slidable in a manner to make a weather tight joint. The practice heretofore has generally been to provide weather strip upon the window frame which requires considerable hand labor in fittin the sash to the frame in cooperative relationship with the weather strip.

This invention has for its object to practically completely obviate the hand labor 1nvolved in weather stripping a window and provides a unique form of strip whereby the strip is carried by the sash and has a flexible portion extending outwardly from the sash to engage the sash runway of the window frame. By this arrangement the sash 1s flexibly held in a central position between the two vertical-side members of the frame and therefore the sash is less liable to bind as even a reater interstice may be provided than usua if desired without affecting the weather-proof efiect secured by the use of the strip.

A further object of the invention is to provide in combination with a sash having oppositely disposed grooves on the side and edge of the sash into which portions of the strip engage under spring tension avoiding necessity of nailing t e strip to place inasmuch as when once assembled with the sash and positioned in the frame the strip .is antomatically retained in lace.

A further feature 0 -the invention is to provide a strip that is adaptable for use upon both the top and bottom as well as the vertical sides of the sliding sash whereby, when the sash is in closed position, the interstice between the upper and lower sash at the meeting rail, the interstice between the lower rail and frame and the top rail and frame are weather-proofed as well as the interstice between the side membersand the sash groove of the frame.

A feature of this invention resides in the construction of the strip which has a portion thereof bent for insertion in a groove provided n one member of a pair and a 1929. Serial lilo. 361,585.

Fig. 5 is a perspective view illustrating the construction of the strip applied to a cross member and a side member of the sash. Fig. 6 is a perspective View showing the end of the cross stri as constructed at this meeting point with t e vertical strip.

Fig. 7 is a perspective view of the end of the vertical strip for cooperative relation with the end of the cross strip shown in 511 its preferred form the strip is of metal sprin side ange or wing 1 and a similar flan e portion 2 normally at an angle one to t e other of less than ninety degrees. The flange 1 terminates in an inbent end portion 3 having the terminal edge 4 thereof bent like in character and consists of the back upon itself to form a smooth edge portion. The flange 2 has the wing member 5 preferably. integrally formed therewith by an inbent part 6 and an outbent part 7 to form a rounded edge 8 corresponding somewhat to the edge of the portion 3 of the flange 1. This rounded edge 8 is thus formed by spaced walls 6 and? and when this portion of the stri is inserted in a groove m a sash rail or ot er character of grooved member as hereinafter described, it is held therein under 5 ring pressure due to the walls 6 and 7 being pressed together slightly in entering the groove. The flexible wing portion 5 has a portion 9 adjacent its edge turned inwardly slightly from the plane of the portion 5 with its terminal edge portion 10 turned back upon itself to form an out turned rounded edge for this flexible strip. The sash frame has the vertical and cross members grooved to receive the weather strip. As shown in Fig. 2 the vertical member 11 has a groove 12 formed irithe edge of the sash riding in the sash groove 13 of the Window frame 14 which is formed between the usual parting strip 15 between the upper and lower sash 11 and 16 and the outer mold or strip 17 while the inner sash 16 has an edge portion riding in the sash groove 18 formed between the parting strip 15 and the mold 19. This sash bar 11 also has a groove 20 in the side face of the sash adjacent the parting strip. These two grooves 12 and 20 are formed in the adjacent faces of a rectangular portion of the frame and provide recesses for the lip or edge 3and the edge portion 8 respective y of the strip to engage.

As the flanges 1 and 2 to which the edge portions are respectively connected are notmally less than ninety degrees apart to position the same on the sash requlres the spreading of these two flanges apartto a ninety de ee angle and, as thls str1p is formed of sufficiently resilient metal, the strip automatically clam s in position; in the respective grooves an with the flexible wing or flange 5 lying in contact with the bottom of the sash groove 13 or other portion of the window frame. This relationship of parts illustrates the reason for turning the edge portion 9 of the-part 5 slightly inwardly toward the flange 2 as it prevents any rough or cut edge .of the flange from gouging into the window frame. It. is also to be noted that this flange portion 5 does not extendto the point of connection of the flange 2 with the flange 1 and thus is spaced from the parting strip shown in Fig. 2 and therefore not in position to gouge into the same. The upper sash is shown in section in Fig. 2 while the lower sash meeting rail is shown in elevation. It will be noted in this view that the strip for the vertical side of the lower sash 16 is positioned in a reverse relation to that shown in the vertical side member Ill-that is, the flexible wing portion 5 and 5 are both turned toward the parting strip and thus are reversely positioned. There is a strip for each vertical side member of each sash, a strip for the the top member of the upper sash and for 21 for the lower sash is outwardly inclined on the meeting side as indicated at 22 while that of the upper sash is correspondin 1y inclined as indicated at 23 and a weat or strip is provided at the lower and inner edgp of this meeting rail 24 of the upper sas it having the flexible flange 5! contacting the. inclined face 22 of the lower sash when in closed position. This rail 24 is provided with grooves 12" and 20, corresponding to the rooves 12 and 20 inthe vgrtical rail 11, into which the respective e e de cri ed. As the flexible strip 5 extends downwardly, the lower sash may be readily raised away from the strip and when brought toclosed position comes properly into contact with the strip which, when the sash is separated, springs outwardly from the inclined face 23 of the meeting rail 24 of the upper sash. This strip introduced between the meeting rails not only closes the interstice therebetween but due to the spring like character of the flexible strip 5 tends to separate the two rails and to hold the sash more or less tightly in engagement with the op osed sides of the respective sash grooves and thus naturally revents rattling of these parts. This flexi le stri on the side rails of either of the sash tens to centralize the sash between the two side grooves provided therefor in the frame member and thus reduces frictional contact of the sash edge with its groove making the window much easier to raise or lower.

This is not only due to the lessened friction but also to the fact that the sash is sustained in its relative s aced relation with the sash groove throug out its length thus tending to cause the sash even when lifted from one side to move freely without tilting or cramping.

In the perspective view Fig. 5, the upper cross member 25 of the upper sash is shown in conjunction with the vertical member 11 to illustrate the construction of the strip for these respective sash rails at the meeting rails at the meeting point. The strip 26 extending across .the. upper rail 25 has its flange 27 and inturned ed e portion 28 cut away at the end as is in icated at 29 and the strip on the vertical sash element 11 ening the flange 3 which, when the parts are assembled as shown in Fig. 5, just meets the end 31 of the flange 28 of the strip 26 on the top rail 25 with the angular portion of the flange 1 overlying the portion 32 at the end of the strip 26. The relative relationship of these will understood portions of the strip clamp as before from the disassembled but relatively positioned parts in Figs. 6 or 7 and the assembled relation in Fig. 5.

When these strips are .mounted in the respective sash grooves provided for the same and the sash mounted in the window frame there is no possibility of displacement of the respective strips but a flange of either of the strips may be tacked in place if desired. This is usually unnecessary as it will be seen from Fig. 5 that the strip across the upper sash may not move endwise nor may the strip for the vertical rail 11, due to the fact that the flanges 3 and 28 practically meet in the grooves of the respective rails provided therefor.

It is to be noted, however, that the strip shown in section in Fig. 3 and indicated generally at 40 terminates slightly short of the parting strip on opposite sides of the window frame. This is indicated in dotted lines in Fig. 2 and when the sash is assembled in the frame the strip may not move out of position as it would engage the parting strlp's. In order to avoid cutting of the parting strip the ends of this weather strip 40 adjacent each parting strip of the frame may be inturned to prevent a cutting edge coming in contact with the strips. The remaining strips which join at the corners of the sash as indicated in Fig. 5 are practically held from displacement one by theother.

By the eneral arrangement of the strip described, it having the spring clamping action and the flexible contact strip, a very inexpensive weather strip is provided requiring no hand labor in the fitting of the sash to the strip as the grooves for the strip may be formed by a rabbeting machine at the time the sash is manufactured and all that is necessary for the workmen to do in assembling the sash in the frame is to cut the strip of the necessary length or it may be provided in standard lengths for standard sizes of windows.

It is further to be understood that the strip, herein described as being ap lied to the outer face of a sash to engage a rame in which the sash is slidable, may also be applied or utilized in any appropriate structure where a space between two opposing members is to be closed irrespective as to whether or not the said members are in sliding relationship longitudinally of, the strip. a
