1 Claim. (Cl. 160-91) This invention relates to improvements in combination screen and storm sash frames.

lt is the object of the present invention to provide a unitarily assembled combination storm and screen sash for removable application to a conventional window frame havingdouble hung windows. ln the device of my invention the combination sash frame is of simple and inexpensive construction and all elements thereof are mounted for unitary handling. ln the specic embodiment of my invention shown in the drawing the combination storm and screen sash has fixed glass and screen sash elements permanently mounted in the frame, and the frame has a way oiset laterally from the plane of the lixed sash with a movable storm sash slidable in said way to selectively expose and block said screen.

The invention also relates to the specific structure of the sliding sash way by which the Sliding sash is readily removed from engagement with said way. ln the preferred embodiment of the invention the sash way channel at one side of the xed storm sash element is relieved to permit lateral disengagement of the sliding sash from the way.

A further object of the invention is to provide means for readily mounting the combination storm and screen sash frame with respect to the sill and lintel of a conventional window frame. in the device of my invention a releasable latch connects the top rail of the sash frame with the lintel of the window frame, the bottom rail of the sash frame and the sill of the window frame being provided with interengaging rib and channel interlock means.

Other objects and advantages of the invention will be more apparent to one skilled in the art upon examination of the following disclosure` In the drawings:

Fig. l is a front elevation of my combination screen and storm sash frame.

Fig. 2 is a vertical cross section taken through my novel storm and screen sash frame mounted in a conventional window frame.

Fig. 3 is a cross sectional view taken along the line 3-3 or" Fig. 1, the sliding storm sash being partly removed from its way.

Fig. 4 is an enlarged fragmentary cross sectional lView taken along the line 4 4 of Fig. l.

Fig. 5 is a fragmentary cross sectional view taken along the line 5-5 of Fig. 1.

A conventional window frame comprising a sill 19 and lintel 11 and having conventional double hung sash 12 and 13 is shown in Fig. 2.

My novel combination screen and storm sash frame comprises upper rail 14, lower rail 15, intermediate rail 16 and side Stiles 17, 22. The upper and lower sash frame lights are defined by a rabbeted upper seat 18 for the glass 19, and a rabbeted lower seat 20 for the screen 21. The glass 19 and screen 21 are permanently fixed within their seats by means of the molding strips indicated generally by reference character 24.

Thus far I have described a conventional double light storm window structure, in which the lower glass has been replaced by the screen 2l, however, in the device of my invention the upper and lower rails 14, 15 and side stiles 17, 22 of the frame are of conventional storm window thickness (DAW). The intermediate rail 16, however, is about one half that thickness, or about S.

The rabbeted seats 1S and 20 for the glass 19 and screen 21 are disposed near the outside face of the sash frame. Near the inside face of the sash frame l provide a seat 25 rabbeted in the top and bottom rails 14, 15 and side stiles 17, 2?.. Side stile 22 is provided with an inwardly facing channel Way 26 which tits into seat 25 and which extends fully between top and bottom rails 14, 15. Side stile 17, however, is provided with an inwardly facing channel way 27 which tits into seat 25 but extends only between the bottom rail 15 and intermediate rail 16.

Accordingly, while the lower light occupied by screen 21 has channel ways 26, 27 along both stiles of the sash frame the light occupied by glass 19 has channel 26 at one side only, the other side being laterally open. Accordingly, a separate storm sash includingglass 28, top and bottom rails 29 and 3@ and side stiles 31, 32 may be manipulated laterally through the said opening (as suggested in Fig. 3) to engage its stile 32 with the upper half of channel 26.

Channel 2d provides a fulcrum in which the stile 32 of the sash pivots in the direction of the arrow 33 for removal of the sliding sash of the frame and in the reverse direction of the arrow 33 to insert the sliding sash in the frame. Stile 31 of the sliding sash is thus received in the portion of rabbeted seat 25 which extends above channel way 27. From this position over the light occupied by glass i9 the sliding sash may be slid downwardly in the ways 25, 27 to intermediate positions and the extreme position shown in Figs. l and 2 in which the glass 23 blocks the light occupied by screen 21.

As best shown in Fig. 5 lower rail 30 of the sliding sash may be provided with a detent pin 36 biased by compression spring 37 to project the pin 36 through hole 38 in side stile 31 and beyond said side stile through the hole 39 in the base web of channel 27 to enter aligned hole 40 bored into the sash frame stile 17. Pin 36 carries an operator handle 43 and knob 45. The handle 43 slides in slot 44 formed in the rail 30. Engagement of handle 43 with the edge of slot d4 limits the projection of pin 36 into the hole 4d.

The stile 17 may be provided with additional vertically spaced laterally extending holes 46, 47 with which pin 36 may be engaged in successive positions of the movable sash. The mechanism at the other side of lower rail 31 is the same as just described and is given the same reference characters in the drawing.

In its uppermost position pins 36 may engage the uppermost set of holes 47. Even though the side stile 31 of the movable sash is no longer confined by channel way 27, engagement of pin 36 in hole 47 will restrain the sash against lateral removal from its way. However, when pin 36 is retracted against the bias of spring 37 the movable sash may be pivoted in the manner shown in Fig. 3 for complete removal thereof.

Upper rail 29 of the movable sash receives the glass 2S within its channel flanges which also clamp the side margin of a weather strip 43 having a portion 49 curled about a ilange of the top rail to dispose the strip between the rail 29 and the intermediate rail 16 of the sash frame for weatherproong. he weatherstrip 43 is of natural or synthetic rubber or other resilient material.

It will be noted that intermediate rail 15 is relieved to provide a bevel at Sti extending across the lower half atented Feb. 12, 1957 3 of the rail from the way on one side to the way on the other to'ss'ue a perfect weather seal when the weather strip is inV closed position. 'A i The movable sash is also provided in its lower rail 30 with a hand grip 52 by which it may be moved from one position to another.

Sill 10 is provided with a step 53 and shoulder 54 against which the lower rail 15 of the sash framey may be seated in the course of mounting the frame in the window opening. The lower edge of bottom rail 15` may be grooved'at 55 for interlocking engagement with the upstandin'g rib 56 mounted on the step 53.

kThe lintel 11 may be provided with a latch bracket 57 releas'ably engaged by the rotatable latch 58 mounted by screw 59 on upper rail 14 of the sash frame. The latch 58 has a handle 62 and a relieved portion 63 opposite the handle and through Vwhich the latch lug 57 passes in the course of applying the sash frame to the window. Latch 58 is then rotated by means of the handle to engagement with the lug to maintain the sash in position.

To 'manipulate latch 58 upper sash 12 of the double hung window is desirably lowered to provide a space through which the installers hands may reach Vthe latch. By disposing the latch at the uppermost part of the sash it is out Vof the reach of children for safety purposes.

I claim:
