trance of weather when in its closed position and which may be securely locked in any one of several adjusted relationshipsv A further objective resides in the provlslon of a novel weather sealing relationship which promotes easy window Other objects will in part be pointed out as the de scription proceeds and will in part become apparent therefrom;-

The invention accordingly consists in the features of construction, combinations of elements,

tion of which will be set forth in the accompany-' tions of a particular use.

Figure 1 illustrates a window frame generally indicated at 20 consisting of a header 22; a sill 24 and

jambs

26 and 28. In'window frame 20 are slidably mounted an inner sash 30 and an' Sash 38 is an inner sash with outer sash 32.

an inwardly which, in the presently described form, to be filled with a rubber-like packing 49 encasbodiment channel 50 is defined (see Figures 2 and 5) by an inner stop head 54 embodying an outwardly extending flange 56 and a parting bead 58 embodying an inwardly extending flange 60. Channel 52 is defined by stop bead 58 including an outwardly extending flange 62 and an outer stop bead 64 embodying an inwardly extending flange 66.

Sash 30 is shown in Figure l to have is

rails

34, 36 and 38 seated within channel 50 and sash 32 has its

rails

42, 44 and 46 seated within channel 52. From the relationship illustrated in Figure 1 sash 30 may be moved to the right, its rails 34 and 36 sliding within channel 50, to a position directly behind that occupied by sash 32. Similarly, sash 32 may be moved to the left, as viewed at Figure 1, its rails 42 and 44 sliding within the guiding channels 52.

The lower rail 36 of sash 30 (see Figure 5) is provided with an inwardly extending flange 68 and an outwardly extending flange 10. In the normal position of sash 30 the extent to which the lower rail 36 of the sash can be seated in channel 50 of sill 24 is limited by the downwardly facing abutment surfaces presented by flanges 68 and I0. correspondingly, sash 32 is provided with an inwardly extending flange I2 and an outwardly extending flange 14 which flanges limit the extent to which lower rail 44 can be seated in channel 52 of sill 44.

In order to assure an easy sliding action of the sashes within the frame members and to prevent the passage of moisture and air around the rails of the sashes each of the sashes is provided around its upper, lower and vertical rails with a resilient hardened stainless steel weather strip of channel-like cross section. More particularly, sash 30 has the outer edge of its upper rail 34 encased by a weather strip 16 held in position by machine screws I8 threaded directly into the upper rail. As best shown in Figure 5, weather strip "I6 is U-shaped in cross section and each of its legs has an inwardly turned flange 80 which is constrained by the natural resilience of the strip itself in face-to-face relationship with the side walls of rail 34. The intermediate leg portions 02 of the weather strip are bowed outwardly away from the side walls of rail 34 and maintain yielding contact between the opposing surfaces presented by flanges 5B and 60. Thus access of air or moisture from outside to inside around rail 34 is prevented by the sealing contact effected by outer leg 82 and flange 60 and additionally by inner leg 82 and flange 56. The double seal which results not only makes a lasting bar against entrance of adverse weather conditions but also promotes an easy and silent resilient sliding action between the top rail of the sash and the header of the frame when the sash is moved horizontally from one position to another.

As best shown in Figure 2, vertical rail 38 of sash 30 is provided with a weather strip which effects a similar double seal between flanges 56 4 and 00 of jamb 26. In like fashion (see Figures 5 and 2 respectively) the upper rail 42 and the vertical rail 46 of sash 32 are double sealed between the flanges 52 and S6 of channel 52 by like weather strips 15.

In order to prevent unintended entrance of adverse weather conditions between

sashes

30 and 32, meeting rail 40 is provided with an outwardly extending flange 84 having a backwardly directed leg 86 presenting an inclined surface 88 facing toward the sash. similar in cross section to the cross section of meeting rail 40 and both rails can be made from sections extruded by the same die. Meeting rail 48 included an inwardly extending flange 90 provided with a backwardly directed leg 92 presenting an inclined surface 94 facing toward the sash. When the sashes are in close position, as shown in Figure 2, surfaces 88 and 94 engage each other with a slight wedging action which assures a firm and extensive surface to surface contact along the flange portions of the meeting rails so that the weather is effectively barred.

The lower rail 44 of sash 32 (see Figure 5) has its lower portions encased by a weather strip 96 of U-like cross section held in place by machine screws 98. Each of the legs I00 of weather strip 36 is provided with a flange I02. The outer flange I02 is interposed between upper portions of flange 66 and lower portions of flange 14. The inner flange I02 is interposed between upper portions of flange 02 and lower portions of flange T2. The legs I00 also may make resilient lateral contact with the opposing vertical faces of

flanges

62 and 66. It will be appreciated that most if not all of the weight of the sash will ordinarily be imposed by flanges I2 and 14 upon

flanges

62 and 56 and therefore that weather strip 96 is maintained under some pressure in a position to form a double seal along the inner and outer edges of rail 44 so as to prevent entrance of moisture or cold air. In addition, however, weather strip 96 also functions to promote a smooth and silent sliding action between the sash and the sill member since the coefficient of friction between the hardened steel margins of the weather strip and the underlying aluminum flanges t2 and 66 is relatively small. Thus weather strip 96 not only serves to maintain a complete weather bar but it also eliminates surface to surface contact between the associated aluminum parts and promotes an ease and quietness of operation not commonly obtained in ordinary sliding windows. The lower rail 38 of sash 30 is also fitted with a weather strip 96 which operates along with

flanges

56, 60, 68 and I0 in the same manner as that described in connection with the weather strip of rail 44 of sash 32. It will be appreciated that the problems of forming an effective weather bar along the bottom of a horizontally sliding window such as shown herein are more substantial in some respects than those attending the sealing at the sill line of a double hung window, for example, because the seal does not part when the sash is moved, as in a double hung construction, but on the contrary must be such as to permit an easy initial sliding action so that the window may be opened without application of undue force.

In order to lock the windows in the position illustrated in Figure 1, outer sash 32 is provided centrally of its meeting rail with a keeper I04 and inner sash 30 is provided with a latch I06. Keeper I04 is a dihedrally shaped plate having a short leg I08 secured by a machine screw IIO ters detent II4 of the keeperto lock the sashes in close position. The sashes may readily be unlocked by lifting latch I06 and sliding sash to an .open position.

It is desirable that the window be fashioned sothat one of the sashesmay be opened slightly.

and there locked in adiustedpositionso as to afiord a controlled amount of ventilation with-.

out rendering thesashes subject to further opening byan intruder. To this end I provide a isconstrained to vertical sliding movement by slot I32 (see Figure 5) through which screw I30 passes and a slot I34 inwhich an elongated hub I35 formed on meeting rail operates.

Latch I28 includes a finger piece I38 by which I the latch may convenientlybe raised or lowered.

The latch is wider as measured transversely with respect to sill 24 than the. opposing faces of

flanges

56 and 60 and accordingly the latch may adjusted fraction thereof and there secured in place by latch I28 and the sash 30 cannot'later be further opened by an unauthorized person outside the window.

In order to prevent unintended .opening of outer sash 32 when its keeper I54 is released by latch I05 on the inner sash I provide a pivoted catch I40 (see Figures 2 and 8) secured by a pivot screw I42 set in parting bead 5&3. Latch I 4!! in-..

cludes a detent portion I44 which in the locked position passes through a slot I46 in a handle portion I48 centrally carried by vertical rail 56. When the detent I44 is engaged with handle I sash 32 cannot be moved away from the provide a large window opening and for this reason the larger the opening that can be effected in any given window, the more satisfactory the window is likely to be during warm weather. My invention makes it possible for the ordinary home owner to remove both of the sashes from the window frame thus creating: a window-"open";- ingof maximum size. It is also tobe noted that l the. sashes may be removed. for cleaning purposes;
