SELF-STORING STORM WINDOW AND SCREEN James D. Reinhardt, Louisville, Ky., assignor to Aluminum Home Products Corporation, Louisville, Ky., a corporation of Kentucky Application August 20, 1952, Serial No. 305,346

18 Claims. (Cl. 160-90) The present invention relates to. a. combination selfstoring storm window and screen of the metal frame type.

Windows of this type are provided with upper and lower glazed sashes, and the invention is directed to such a window having a screen sash which is movable from an upper storage position to a lower ventilating position.

According to one feature of the present invention the outer or upper window sash is provided with a catch operable from the outside which requires lifting of the outer sash to release the catch, and this upper sash. has an interlock with the inner or lower sash, so that by locking the lower sash the upper sash is locked against the initial upward movement required to release its catch. However, when the lower sash is raised access to the catch of the upper sash can be had from the inside through the window opening.

Another feature of this invention involves a construction which enables the provision of a double interlock between the screen sash and its adjacent glazed sash so that the screen can be used for ventilation in the upper part of the frame when the upper sash is lowered, or can be used for ventilation in the lower part. of the frame. When the screen sash is in its lower operative position it forms an interlock with the adjacent raised glazed sash which prevents entrance of insects. When the screen sash is in its upper position and. the adjacent glazed sash is in its lower closed position the screen sash also forms an interlock with the glazed sash. To enable the projecting parts of the two sashes to pass for raising or lowering the respective sashes the screen sash is mounted to have movement toward and away from the glazed sash, and a spring is provided to hold the screen sash against the glazed sash.

In addition to the above features the invention comprises an arrangement by which adl three sashes may be removed from their respective channels. This involves openings or cut outs in the respective outside and inside sash channels, with the screen sash confining the inside sash in its respective track in raised position.

The invention will be described in greater detail in connection with the accompanying drawings illustrating a preferred embodiment of the invention by way ofexample, and wherein:

Figure 11 is a similar view illustrating removal of the upper sash;

Figure 12 is a fragmentary side elevation of the frame; and

Figure 13 is a fragmentary plan view of the frame:

Referring to the drawing the window frame comprises abottom rail 1, a top rail 2 and oppositely arranged stiles 3 and 4 (Fig. 4). Each stile comprises an H-bar 5 (Figs. 1 and 13), which receives a. channel bar 6 between the flanges 5a, 5b. The H-bar has internal flanges 7-7 (Fig. 12) which receive leaf springs 8, these flanges being peened to hold the springs in place. The springs allow telescopic movement of the channel bar 6 to permit the frame to be inserted in a window opening, and urge the channel bars out when the frame is in position. The top rail. 2 (Figs. 4 and 13) of the frame comprises a channel with a base 9, an exterior ribbed flange 11, an interior flange 12 and a middle flange 13.

The bottom raill (Fig. 4) comprises a channel member providing a base 14 with an exterior ribbed flange 15 and an interior ribbed flange 16. A rib 17 extends across the top of the. channel base and a J-shapedpiece 18 is fastened to interior flange 16. The bottomrail telescopically receives" a channel 19 which is allowed to.drop by gravityv to fill in thei'space-between thebottom rail land the windowopening; The Window frame may be held in the window. opening byv countersunk screws or the like extending through? the frame (not shown). The bottom rail; stiles and top rail are held assembled by suitable sheet metal. or self tapping screws.

Stile 3 (Fig. 1) has an-intermediate flange 21 in substantially the same plane as middle flange 13 of the top rail. This flange 21 terminates at 22Inear the mid dle of the frame, and, stile 4 has a similar intermediate flange 23 (Figs. 4 and 5) which terminates at 24, substantially at or below the level of edge 22. The distance between the edge 24 and the base 9 of the top rail. is slightly greater than the height. of the exterior glazed sash 25. The bottom rail 25a of sash25 providesa channel in which is located a bell crank latch. 26 on a pivot 27 providing an operating end.26a and a detent end 26b. As shown in Figure. 6, the detent end enters an aperture 28 in the stile 4. A similar latch 29 at the other end cooperates withv an aperture 31 in stile 3. These detents are so balanced that the weight of the operating levers urge the detent ends into the apertures.

Referring to Figures 6 and 11, when the screen sash and lower glazed sash are removed the upper sash can be removed as follows: the upper sash is raised up against base 9 of the toprailand the latches are manually operated to raise the operating ends 26a, thus retracting the detent ends 26b from the respective apertures. The sash now is high enough so that the detent ends will clear the top edges 22, 24 of the flanges 21, 23 as the sash is drawn inwardly to the dot and dash line position shown in Figure 11. The sash then is drawn downwardly to release it from flanges 11 and 13 so the sash can be removed. It will be observed there are no internal flanges in the upper half. of the window frame to interfere with the removal of the sash. In normal assembled relation, as shown in Figure 4 the detents hold the sash in position so that flange 13 prevents the sash falling inwardly outof place while flange 11 prevents the sash falling outwardly. If desired, openings similar" to aperture 28 may be provided at various elevations in the frame, so the sash. can be lowered to corresponding intermediate positions;

When the lower sash 33 is in its upper position (Fig. 5) the upper rail 33a engages. between outer sash 25 and flange 12, and the flange 13 has its edge offset at 33c to act as a stop. At the bottom rail 33b of the sash a channel is provided for a detent rod 34 which is biased outwardly by a spring 35 between the end of the rod and an abutment 36 formed by striking out a tab from the bottom sash. An operating knob 37 extends through a cut out 38 in the sash. This rod is pressed into an aperture 39 provided in stile 4. A similar detent is provided at the opposite edge of the sash, and the engagement of these detents in their respective apertures 39, 41 hold the sash in its upward position between the flange 12 and sash 25. To lower the sash 33, the handles of the latch are pressed toward the middle to release the latches, and the sash then can slide down between flanges 21 and 42 of the stile. The flange 42 may be a continuation of flange 5b. The flange 42 terminates below edge 22 so that with the screen removed, the lower sash can be removed by raising it in the frame to the upper position, then drawing it inwardly as shown in Figure 10, then downwardly at an inclination to clear flanges 42. Apertures are provided in the stiles so that the lower sash can be held by the detents at various levels, and holes 43 at the bottom position enable locking of the lower sash. In the lowermost position of sash 33 the rib 17 is received in the lower channel to hold the sash against rattling, and the operating knobs 37 can turn inward to allow full closing of the sash. To open the sash it is necessary only to optilrate the knobs 37 to release the detent and lift the sas The lower rail 25a of sash 25 on the inside has a projecting flange 44 providing an upwardly open channel, and the upper rail 33a of the lower sash is provided with a similar rib or flange 45 providing a down- Wardly open channel. When the two sashes are in their closed positions the flanges 44, 45 overlap and interlock so that the upper sash can be lifted only together with the lower sash. When the lower sash is locked in closed position the upper sash is interlocked therewith by the flanges 44, 45 so that the upper sash cannot be raised sufliciently to release the detent ends of the latches from their locking apertures. Thus, it is not possible to release and lower the upper sash when the lower sash is locked in its lowermost position. The upper rail 33a has a similar rib 46 on its inside face, and the bottom rail 33b has a rib 47 providing an upwardly open channel for a purpose presently to be described.

The stile 3 has an L-shaped flange 48 secured to the face of flange 5b so that its edge terminates substantially in the plane of the cross web of the H-bar, and the middle portion of this flange is cut away, as indicated at 49. A similar flange 51 similarly cut away is provided on stile 4. These flanges provide a guide for the screen sash 52. The sash 52 is suitably constructed to provide a peripheral channel 53 around the sash, this channel being wider than flanges 48 and 51 so the flanges may be received in the channel with a very loose fit. Within the screen channel at each side is located a bowed leaf spring 54 having a bent end 55 which anchors the spring in a recess 56 in the sash. This spring preferably has a transverse head 57 at its middle. In normal operative position the flanges 48, 51 are received between the spring 54 and the wall of the channel 53. This spring provides suflicient friction to hold the screen in raised or partly raised position.

At the top the screen sash has a rib 53 forming a downwardly open channel so that when the inner sash is raised and the screen sash is lowered this channel is adapted to interlock with rib 47 so as to prevent entrance of insects. The bottom rail of the screen has a similar upturned rib 59. In raising the screen sash the bottomrib 59 must pass over the bottom rib 47 of the lower glazed sash. This is provided for by the springs 54 which yield to allow such passing. This arrangement of upper and lower interlocking ribs allows the screen sash to be used in the upper window portion for ventilation when the upper and lower glazed sashes are lowered. In such position the interlock between ribs 46 and 59 prevents entrance of insects between the screen and the lower sash, and the spring mounting of the screen sash allows rib 46 to cross rib 58 on the screen in raising or lowering the glazed sash or screen. When the screen sash is in its lowermost position the channel 53 in the lower rail receives the J-shaped member 18 to hold it against rattling. In this position the handle 61 latches under the member 18 to lock the screen in position.
