Application July 16, 1952, Serial No. 299,457 7 Claims. (01. 160-90) My invention is particularly concerned with an improved type of combined storm and screen window construction incorporating a sash supporting frame having triple tracks, and it has for its general object a triple track combined storm and screen Window structure wherein screened ventilation is enabled through either the top or bottom of the structure or both without removal or replacement of any of the sash members.

In my invention an expansion frame adapted to be secured about a window opening carries a sash encasing frame provided with three pairs of rails up and down which there is adapted to slide a pair of storm window sashes and a screen sash. The screen sash serves to provide ventilation through the lower portion of the window opening; to have ventilation through the upper portion there is provided a smaller screen sash. This latter sash does not move vertically, but is arranged to move rearwardly or forwardly of the encasing frame.

The invention, while it could well be used in lieu of the conventional double hung windows of a building, represents an auxiliary structure for double hung windows, and it is intended to occuply that space in the window opening that exists between the regular window and the outside of the building. In its later use it provides many advantages, eliminating many defects associated with conventional storm and screen window structures.

Inserting or changing storm or screen sashes with the different seasons is not required with my invention, as the storm and screen sashes are already incorporated in the structure and are operable much in the manner of double hung windows. The screen sashes and the storm sashes may be adjusted as desired and, regardless of the season, without removing or replacing any of the sash members.

In the use of a structure embodying my invention ventilation may be had through the window frame opening either at the top or bottom, or both; ventilation may also be out 01f entirely by the storm window sashes, if desired, particularly in cold weather.

The invention further lies not only in the various features whereby the foregoing advantages are obtained, but also in the novel arrangement and general organization of its various co-operable elements.

The invention together with its many advantages will become readily apparent as this specification unfolds in greater detail and as it is read in conjunction with the accompanying drawings 2 wherein a preferred and specific embodiment of the invention is illustrated. In the drawings:-

Fig. 1 is a front elevational view of a combined storm and screen window structure embodying my invention;

Fig. 2 is a cross section taken .on the lines 2 -2 of Fig. 1;

Fig. 3 is a fragmentary View of part of a sash member;

Fig. 4 is a front elevation of the small screen sash;

Fig. 5 is a perspective view of the small screen sash illustrating the top, rear and one side thereof; and

Fig. 6 is a sectional view showing the small sash displaced to its middle position.

In detail, the invention includes an expansion frame I comprising upper and lower broad strips 2, 3 and a pair of upright broad side strips 4. The expansion frame is adapted to be aflixed in suitable manner, such as by fasteners 5 to the outside of a building about the conventional window opening. The expansion frame serves to carry by proper means a sash encasing frame 6. For this purpose a continuous channel 1 is provided in the inner side of the expansion frame. In this channel there is adapted to be received and contained a tongue 8 of the encasing frame member 6. To allow frame member 6 to be received by its tongue in the expansion frame I, the upper strip 2 is preferably formed free of the uprights 4. In the assemblying process the tongue 8 on three sides of frame 6 is received in the channel 1 of the uprights 4 and the lower strip 3. Next, the strip 2 is placed in its proper position at the top to complete the frame, in such manner that tongue 8 of the upper side of frame 6 is contained in the channel 1 of the upper strip 2.

The sash encasing frame 6 further includes top and bottom cross walls 9, l0 and a pair of upright side walls I I, of which but one is shown, the other being identical, suitably joined to one another in the form of a box with open front and rear ends. Frame 6 is further provided to carry for vertical sliding movement therein three sashes I4, I 5 and I6. Sashes I 4 and it are each closed over with a glass panel [1, while sash l6 carries a screen panel !8. Each sash member comprises upper and lower cross pieces I9, 20 and a pair of side pieces 2|. The lower cross piece of each sash contains lifting means, such as a finger well, not shown. In each of the sash uprights 2| is a channel 23 by which each sash is guided for vertical sliding movement upon a separate pair of rails 24 carried by the inner walls of the upright side members ll of frame 6. The outer pair of rails, those nearest to the expansion frame I, serve to guide one of the glazed sashes, here sash M; the middle pair of rails serve to guide the glazed sash [5, while the inner pair of rails guide the screen sash l6.

Rails 24 are carried, three to each side, on the inner faces of walls ll. While the rails may be an integral part of walls H, or removably inserted in'suitable manner in slots therein; here, however, they assume a different and preferred form. In this form there is provided for each side wall H a pair of plates 21, 23. In each plate there is formed a set of three rails 24 parallel to one another and uniformly spaced apart. Plates 21, 28 of each pair are removably secured to the inner face of each side member H, one above the other, in such manner that the rails of the lower plate 28 are in vertical alignment with the rails of the plate 21 above it. The several rails of each side wall are of equal height and extend from the base of the frame to a short distance from the top, leaving a space 29 without rails at the top of each wall ll.

Between the wall spaces 29 at the upper portion of frame 6 there is provided to move rearwardly or forwardly of the frame, as desired, asmall sash member 30 having a screen panel 3 I. This small screened sash occupies about onesixth of the opening of frame t, and it is intended to provide screened ventilation through the top portion of the window opening. Suitable means is provided to enable this rearward or forward movement of sash 30. It is guided in this crosswise by suitable Crosswise of the space 29 in each sidewall H is an elongated slot 32 through which extends a pin.33 projecting one from each side of uprights 34 of the small screen sash 3G. The sash is carried rearwardly or'forwardly of slots 32 through spring means co-operable with the raising or lowering of the glazed sash members is and it. A pair of curved or s springs 35 affixed at one end to the top side of wall a and at the other end'to'the rear of sash uprights 3d serve to tension sash 30 in an erect position constantly forwardly of frame 6. Sash 39 is limited in its forward movement to a position in alignment with and above sash M by pins 33 abutting the forward ends of slots 32.

Glazed sashes I4 and 15 are of equal height and each. is adapted to close off a half portion of the Window opening. Screen sash it could also be of .a height equal to one of the glazed. sashes, however, it is desirable that sash it, when compin and slot means.

bined with sash 30 equal the height of one of the glazedsashes. The smallersash 3t is intended tOLPIOVldB screened ventilation through the upper portion of the window opening, while the larger sash 116 is intended to serve the bottom.

To. enable sash 3D to move rearwardly of frame 6 against the tension of springs 35, the lower crosspiece of sash 39 is adapted for camming action in conjunction'with either of the sashes i4, 1 5 or 16, whereby sash 39 may be progressively moved rearwardly. To effect this action, the bottom side 42 of the lower crosspiece of sash 3B is inclined rearwardly from ahigh point on the. forward edge of the crosspiece to a low point on the rearward edge thereof; and the top side 43 ofthe upper crosspiece l9-of each sash it, it and IG is inclined in a complementary manner.

In explanation of the use and" operation of the structure reference is directed particularly to Figs. 1, 2 and 6. The expansion'frame 'l is intended to attach to the outside of a building structure, while the frame 6 encasing the several sashes is intended to occupy the space between the outside and the regular window of the building. In Fig. 2 the small screen sash 3B is shown tensioned to its foremost position above the lower sash l4, and sash I5 is in its lowered position. To move sash 3B rearwardly so as to out 01f ventilation from thetop of the structure, sash I4 is raised to bring the cam surface 43 of its upper cross piece against the complementary cam surface 42 of sash 30. Further and a .full raising of sash M will cam sash 30 rearwardly against the tension of springs 35 to assume aposition to the rear of sash M as in Fig. 6. During the camming operation sash 30 is forced off the inclined surface of sash l4 and moves to the rear as it rises upwards in front of it as in Fig. '6. Sash 30 is guided in its rearward movement by the pin and slot means 32, 33 at the sides thereof; It is plain that fully raising the middle sash 15 will ina similar manner force sash 30 to its rearmost position above screen sash l6. When sash an is in the latter position with the two glazed sashes-l4 and I5 fully raised, screen sash It may in a-lowered position provide screened ventilation through'the'bottom of the window opening. 7

It is plain from Fig. 6 that if the first sash I4 is lowered, springs 35 will tension sash Sllback to its normal position.

When sash 3a is in its normal position, sashes l4 and [5 may be partly raised and screen sash It lowered, whereby ventilation will be afforded through both the top and bottom of the structure.

Due to the slight separation of sashes M, 1-5 and Hi from one another, means is provided to prevent entrance of cold air, insects and other foreign matter from between the sashes. This is enabled by a cross strip 41 located along the rear marginal edge of sash 30, which strip overhangs the sash below and to its rear.

When sash 3a is in its normal forward position and sash It is in its fully lowered position, sash I5, the middle sash, may be raised until its uppermost edge contacts the cross strip 41 of sash 30. In this arrangement ventilation can be had solely through the sash 30 at the top of the structure. When sash M is fully raised so that sash 3B is displaced to its rear, and while sash I5 is in its lowered position, ventilation is .cut off entirely.

Thelower half of the window opening may be made fully open so as to provide. free access through to the outside o'f-the building. This is accomplished by successively and fully raising sashes i i and &5 so as to displace-sash 3!) to its rearmost position abovesash'i-B, and finally by raising sash H5 until'it contacts sash 3i].

Conventional well known means; such as springs, not shownyinthe channels 23 .of sashes l4, l5 and it serve in conjunction with conven tional grooves, not shown, in which they engage to tension and to hold the sashes in their various raised positions.

The various elements. of the structure are preferably fashioned of light, stainless metalfsuch as aluminum or other suitable metal. l 'I While I have described what'I considerto'bc a highly desirable embodiment of'my invention, it is my intent, however, to claim'all such forms OfthBlIIVELIItiOII as may bereasonably construed tob'e within the spiritof the invention .and with in'thescope'of'the appended claims.
