The combination storm and screen sash assembly that embodies an illustrative part of the present invention, comprises a sash frame that is made up of a pair of hollow side members 1, a top cross bar 2, a middle cross bar 3, and a bottom cross bar 4, that are secured together at their junctions in any appropriate manner, as by welding, rivets, or the like.

The individual sash frame members, including the cross bar portions, are preferably hollow and are made of shaped, suitable sheet material that may have its edges l the various sash frame members, such as the side membe outdoor ilanges 6.

The sash frame member that is shown in Fig. 14 is formed from a single strip of material and, if welded together at all, may be welded along its panel receiving outdoor ange 7.

The sash frame is mounted in a building aperture with preferably a sliding seal in adlustably secured contact with the sash frame.

In the structure shown, a pair of seal side members 8 closely abut the building aperture side casings 9, the sliding seal top member 10 abuts the head casing 11, and the sliding seal bottom member l2 rests on the sill 13. Esch of these sliding seal members may b e adjusted toward or away from a part of the sash frame, as shown in dot and dash lines 8a in Fig. 4, or longitudinal thereof, so that no objectionable crack appears between the seal .and the building aperture casing.

The sliding seal shown in Fig. 5, is of substantially channel shape, with a plurality of side walls extending from a base portion. Where desired, the modied telescoping seal member that is shown in Fig. l5 may be used. In this structure the inner telescoping seal 85y slides longitudinally into the outer telescoping seal 86. 'Ihe division is preferably substantially midway between the ends of the assembled seal.

The sliding seal members are secured in the building aperture' at desired locations by suitable means, such as by the screws 14 that enter the building aperture blind stop 15 and that draw the sash frame contacting, preferably inclined, free edges 16 of the seal members into close clamping engagement with the contacted parts of the sash frame. The sash frame screw holes, it will be noted, are preferably, altho not necessarily, offset slightly with respect to each other so that the screws 14 have suicient slant to draw the seal tightly against the casing of the building aperture. Where the mold strip structure is used, the weld strip 5 is cut away, as at 17, to provide ample clearance for the proper positioning of the screws.

The bottom seal member l2 has a desired number of drainage and breather apertures 18 in the indoor side thereof for permitting a limited air circulation through the sash. It also has a fluid drainage aperture 19 that is offset and not in alignment with the apertures 18 and which permits the escape of any wind-borne water or the like that is carried into the interior chamber of the hollow frame bottom bar 4 through the ventilation louvers 20 that are disposed in the outdoor side of the bottom bar 4,

and that ows into the seal bottom member through the l drain aperture 21 in the sash frame bottom bar 4.

Ample areas of the seal bottom member 12 and the sill 13 are preferably exposed to the drying action of air to minimize the retention of water therebetween. This end is accomplished in the disclosed structure by the edge 4 the force distribution of the weight from the sash assembly through the seal bottom member 12 to the sill 13.

. Suitable means is provided for permitting the passage of air through the sash on pleasant winter days, auch as the shutter 22 that is provided with the hand grip 23 and that is opened in any desired manner, as by causing its rotation on the pin 24. The stop 25, or the like, arrests the shutter 22 in its closed position.

The bottom cross bar 4 receives a panel frame, such as thev frame 26 of the glass panel that is shown in the lower panel aperture, in a suitable upwardly opening channel, such as that formed by the. outdoor panel receiving ange 27 and the indoor flange 28 that may be inclined or not, as preferred and the cross brace 21a that forms the base of the channel. Suitable sash frame packing 29 may be interposed between the panel frame' and-a part of the panel receiving channel, if desired.

The middle cross bar 3 of the sash frame has a downwardly opening channel of ample depth to permit the easy clearing of the bottom bar indoor tlange 28 onthe introduction of the panel into the lower panel aperture, as by positioning the brace member 40 above the middle of the cross bar, or by similar provision.

The middle cross bar lower tlange portion of the indoor strip 31 is preferably, tho not necessarily, of sufllcient length to support a panel in the lower panel aperture when the lower bar of the panel frame is seated in the upwardly opening channel of the bottom cross bar.

The middle cross bar has an upwardly opening panel trame receiving channel of which the brace 30, or similar panel supporting means, forms the base or bottom and the upper ange portions of the indoor strip 31 and of the outdoor portion of the middle cross bar 3 forms the sides.

The top cross bar 2 of the sash frame opens downwardly in a panel frame receiving channel of ample depth so that the bottom bar portion of the panel frame may clear the upper ange edge of the middle bar inside strip 31.

The top cross bar brace 32 imparts strength and firmness to the top bar by being positioned preferably rather low in the top bar and by being secured, as by a weld, or the like, to both the outdoor part of the top bar and to the indoor portion 33.

During the winter months glass panels are positioned in the panel receiving apertures in the panel frame. The glass panel frame 26 preferably extends along theperiphery of the glass 34 to provide a uniform thickness for 'the edge of the panel and to permit the handling of the panel without danger'of hand injury froman exposed glass edge. A desired packing material 35 may be interposed between the glass and the frame, if preferred, as shown in Fig. 5. The packing material, if soft and resilient, prolongs the life of the glass by its absorption of shocks or torque to which the panel frame may be subjected.

The packing 35 is shown in Figs. 13 and 16, as having the defiector portion 36 that extends along the glass beyond the frame and that imparts an attractively finished appearance to the panel. The defiector portion 36 simplies the cleaning of the window panels by detlecting the engagement of the lower face of the seal bottom member l2 with the inclined sill 13.

The screws 14 are preferably drawn suiciently tight so that the side members of the seal substantially support the bulk of the weight of the sash assembly to provide substantially a oating sash and to minimize the setting of the sash assembly on the building aperture sill. The weld strip 5 on the sash frame bottom bar 4 may, if desired, be disposed on the indoor side of the lower face of the frame bottom bar to shorten the moment arm .in

water and the rubber strips of a'window cleaning tool beyond the junction of the glass and the packing without the deposit of objectionable water at the edge of the glass.

The deector portion 36 may also protectively overlie the edge of the glass panel frame and, if desired, extend continuously beyond the sash frame packing 29 and the edge of a sash frame panel receiving channel, as the strip `37 that is shown in Fig. 16, to protectively deect the flow of water thereacross, where the packing 35 is of waterproof material, such as rubber or the like.

The glass panel frame 26 is secured together at the corners in any suitable manner, as by having its overlapping parts welded together, as shown in the lower corner of Fig. 8. where the frame is of metal, or the like.

The glass panel frame may be adapted for the replacement of glass therein, if desired. In the structure that is shown in Fig. 8, one or more sections 38 of the frame, with its packing 35, may be removably secured to the remainder of the frame by suitable means, such as by the screws 39. A portion of the glass may be removed to provide clearance for the screw, as where the corner is cut away at 40, or the like.

During the summer months the glass panels are kept in storage and screening panels are in use in the sash.

The screen wire 41 in the screen panel is mounted on the screen frame in any suitable manner, as by having its edge secured by welding, or otherwise, where thek core is of metal or'the like, to the screen frame core 42, that may be solid bar stock, as shown, or hollow to decrease the weight of the panel, as preferred.

For the present use it has been found that ample strength is imparted to the corners of the screen panel where the core 42 is abutted and spot welded deeply at the line of abutment, as at 43, on the face and the outer edge of the core 42.

A finished appearance is imparted to the screen panel frame in any suitable manner, as where sheet material 44 is applied to overlie the contact between the screen wire 41 and the core 42, or where a desired sheet material 4S substantially incloses the frame core 42.

The panels are preferably secured in the panel receiving apertures of the sash frame by suitable means, such as the keepers 46, that are operatively interposed between the panel and the sash frame in any preferred manner.

In the illustrated structure shown, the keeper 46 is rotatably mounted on a panel frame by suitable means, such as by the rivet 47. The keeper is provided with a suitable hand operating means, such as the ring 48 that is advantageous in that it may be folded back against the sash frame so that it is not objectionably visible from the outdoor side of the sash.

The sash frame engaging end of the keeper contacts the sash frame in any desired manner to firmly secure the panelwithin the sash frame. In the structure shown, the sash frame is apertured, as at 49, for the reception of the sash frame engaging end of the keeper. The sash frame aperture may, if desired, terminate on a level with an edge of the keeper, as at 50, so that leverage is available to lift the panel up out of the channel in which the lower part of its frame rests, or to press the panel frame down into its channel, as desired. i

Where desired, an edge 51 of the aperture in the sash frame may be inclined sufficiently so that, as the sash frame-engaging end of the keeper is operated against it, the panel frame is pressed toward and is secured closely against the sash frame packing 29.

[The modified storm sash and screen assembly that is shown in Figs. 17-27 inclusive of the drawings comprises a plurality of sash frame members that are preferably shaped from single strips of material. The sash frame comprises a pair of hollow side members 52 'that are provided with outdoor panel supporting flanges 53 against which panels are removably positioned] [The top bar S4 of the sash frame comprises hollow portions above and below a partition element or strengthening brace 55. The outdoor ange 56 is spaced from the indoor ange 57 suliiciently so that the indoor flange may yieldingly permit the insertion of the frame of a removable panel therebetween] [The bottom cross bar 58 of the sash frame is hollow and terminates upwardly in a panel receiving channel 59. Provision for permitting ventilation through the bottom bar is made by suitable means such as the rain deflecting and air-admitting, downwardly opening louvers 60 in the outdoor face of the bottom bar, and a shutter 61 that is movable, as by being mounted on thepin 62 or the like, and that is operated by suitable means, such as the handle 63. A rest for the shutter in its closed position is provided, such as the stop 64.]

[A suitable, yielding sill sealing means, such as the spring metal strip 65, is disposed at the lower edge of the be welded in place or not, as desired, and serves to subl stantially close the junction between the sash frame and the sill 13 on which the sash frame rests. Suitable apertures 66 in the bottom bar permit the draining away of any wind borne water that may enter the bottom cross bar thru the louvers 60.]

[The sash frame is adjustably mounted in the building aperture casing in a desired manner, as by being adjustably interposed between the blind stop 15 and a sealing strip 67 that is secured in place by suitable means, such as the screws 6l. The sealing strip 67 is drawn into close pressing engagement against the frame of the sash and serves to close against the admission of wind, any crack that may exist between the sash frame and the building aperture side casings 9 or the head casing 11.]

[Where the building aperture is of a size that requires a plurality of removable sashes, a suitable middle cross barfs provided, such as the middle bar 69 that opens upwardly in a panel receiving groove or channel 70 having spaced wall elements one of which is inclined at an acute angle to the plane of the panel, as shown. The downwardly depending spring flange 71 is disposed on the indoor side of the middle bar and is spaced from the stiff outdoor part of the bar so that the upper edge of the removable panel may be inserted therebetween. The brace or partition element 72 extends across the middle bar 69 and assists in imparting rigidity thereto] [A modified middle cross bar 73 is shown in Fig. 25 of the drawings, wherein a double thickness of metal, as in the middle bar 69, forms the outdoor side of the bar and extends toward the indoor side thereof to provide the brace portion 74, from which it divides into the more resilient single thicknesses of metal and provides the upwardly and downwardly extending spring indoor panel gripping flanges 75. The upwardly and the downwardly opening channels that are lso positioned yieldingly receive upper and lower panel frames thereinto] [The parts of the sash frame are preferably secured together by suitable overlap structures, such as those that are shown in Figs. 26 and 27 of the drawings, and may be welded, riveted, soldered, or otherwise fastened toimpart rigidity to the frame] [The removable glass panels comprise the sheet of glass 76, that preferably has its edge protectively enclosed in a frame of suitable material, such as the metal 7,7 that may be replaced where desired, by rubber, a plastic, a fabric or the like, to minimize the breaking of the glass and to prevent cuts and injuries to-the hands of anyone handling the panels, and also to insure a panel edge of uniform thickness thruout its length] v [Suitable means may be used, if preferred, for rigidly securing the panels in the sash frame. The form of securing device that is shown in the Figs. 22 and 23, com-y prises a J-shaped keeper 78 that`1s made of metal or the like, and that is movably mounted on the panel frame 77 by suitable means, such as the rivet 79. The tip of the longer arm of the keeper 78 enters an aperture 80 in the side sash frame 52 to lock the panel in position. The aperture 80 in the side sash frame 52 preferably terminates in an upper edge that is substantially level with the upper edge of the keeper 78, so that'by pressing down on the keeper handle 81 the bottom edge of the sash panel is pressed down into the groove into which it seats. The reverse action is accomplished where the keeper lower edge is level with `the lower edge of the aperture 80.]

Removable panels are inserted and secured in the sash frame from preferably the inside of the building. The panels may be of sheet metal during such time as the building is unoccupied, glass for winter, and screen for summer.

The combination of the resiliently yielding toppbottom and side sealing members 8, 10 and l2 provides a supporting frame that may be used in window openings of consize and shape of window assembly that is secured in place lreceiving frame to seat upon side and transverse walls of by the yielding pressure of the contacting edge portions lof the sealing members. This edge Acontact is of suficiently small area to minimize the heat transfer between the metal surfaces. The yielding contact removes all strain incident to expansion and contraction of the building or of they, window parts from-one another, so that there is no warp-j',

ing or objectionable strains imposed upon the window` assembly. This oating or free moving action of the window assembly prevents the development of Vobjectionable cracks or openings and maintains adequate seal be-' tweenl the'window assembly and the window casing during all weather conditions.

The formation of the dead air spaces or cells, by reason of the hollow sheet metal construction of these parts, and the small area yof contact between metal surfaces, minimizes the transfer of heat through the assembled unit.

The dead air spaces or cells are so divided by thestructural formation of the metal parts that there is a mini-- mum circulation oi' air within the structure and a minimum replacement-of the air conilned within the structure.

The dead air space or air cell formed by the sealing members 8, and 12 overlap the dead air space or cell formed within the window frame, the only contact between the metal in the side wall of the sealing members and the window frame being at the inner edge portionsoi the sealing members that engage the side wall ofthe sash trame.

For the purpose of further minimizing the transfer oi heat and providing additional heat insulating properties tothe structure, the metal parta are given an internal and l external surface iinish of a bright reilecting metallic paint y or coating, such as aluminum paint, chrome plating or other radiant heat reilectingmaterial.

It is to be understood that the particular constructions of sash frame members, seals and panels that are `shown and described herein are presented for the purposes of illustration and explanation and that various modifications in the particular shapes, constructions and applications may be made without departing from the invention as defmed by the appended claims.

A building aperture sash assembly comprising, in combination, a casing forming the periphery of a generally rectangular window opening for a building, a rigid, rectangular sash framedisposed in said opening, said sash frame comprising side and transverse metal bars connected together for interchangeably receiving glass and screen panels, a channel-shaped hollow seal for each of said side and transverse bars, each of said seals having three integral sides of resilient sheet metal, including a pair of spaced lianges straddling and gripping a frame bar in resiliently compressed siidable engagement with oppo site sides thereof for angular, longitudinal, and transverse adjusting movement with respect thereto in the general plane of said opening, and screws passing through at least one of the sides of an opposite pair of said channel-shaped seals and entering said casing forpermanently firmly securing said pair of seals against said casing and securing said frame in said opening, the portions of said screws within a channel-shaped seal beingconfned to clearance spaces provided between the base of such seal and the adjacent edge of said frame and spaced from the frame to avoid interference with subsequent self-adjusting movement of the frame relative to the seals.

I8. A building aperture sash assembly comprising, in combination, a casing forming the periphery of a generally rectangular window opening for a building, a rigid, rectangular, sash frame disposed in said opening, said sash frame comprising side and transverse metal bars connected together ,for interchangeably receiving glass and screen panels, a channel-shaped hollow seal ior each of said side and transverse bars, each of said seals having three integral sides of resilient sheet metal, including a pair of spaced flanges straddiing and gripping aframe bar in resiliently compressed siidable engagement with opposite sides thereof for angular. longitudinal, and transverse adiusting movement with respect thereto in the general plane of said opening, and screws permanently passing through said spaced flanges of an opposite pair of said seals and entering said casing [or firmly securing said pair of seals against said casing and more firmly clamping both side flanges thereof against said frame, the portions of said screws passing between said spaced flanges of a seal belng disposed between the base of such seal and the adiacent edge of the frame and spaced from,the frame to avoid interference with subsequent self-adjusting movement of the frame relative to the seais.

19. An auxiliary window for use with a permanent one, including an outer member attachable to the permanent window, said outer member being composed of sides and ends each of channel formation having their channels facing inwardly, the sides and ends being free of con- 12 nection with each other to provide for adiustabiiity in attachment and for expansion and contraction, a paneled inner member having sides and ends receivable in the channels of the outer member, the sides and ends of the inner member being disposed with free space between same and the corresponding sides and ends of the outer member, whereby to provide for tractability of the inner member relative to the outer member, said inner member having outer edges that are relieved to form slots opening outwardly toward the channel bottoms of the outer member, fastening elements that extend through the sides of the outer member and through the slotsl of the inner member for permanently connecting the outer member to the cas ing of a permanent window, said slots being wide enough in directions parallel to said outer edges to receive said fastening elements with substantial clearance permitting subsequent shifting of the inner member with respect to the fastening elements in directions parallel to the slotted outer edges of the inner member, and yieidable means to seal the outer portions of the channels against the ingress of air into the spaces aforesaid between the two members.
