This invention relates to a storm window and, in particular; to a metal storm window" charac"- t'eri'z'ed by tightly Sealed joints, great'dur'ability and relatively low cost of manufacture.
StOrm windows in various designs and styles and of metal-as well sis-wood constructionhave been proposed heretofore. All'types'of su'ch' winddws with which l ain 'familiar, however, are open to several Objectio'nsi Wood storm windows are generally not capable of ei'f'ectively'excluding' outside air 7 because the joints cannot be tightly sealed. In addition, they deteriorate" under weathering. "Metal stormwindows as previously known hav'e'been quite costly. Also, the construe tionusuallyeinployed is suchthat replacement of a broken panerequires that the sash be re turned to the factory. Still further, the" sash proper, without glass, lacks rigidity and any "stress applied is resisted partly by "the glass ncreasing the likelihood of bre'akagethe're'off I I have invented a novel construction :of storm window whereby the" above shortcomings of previous designs are" largely overcome" or eliminated.- In a" preferred embodimentliny window comprises a continuous unitary frame adapted to' fit'over the window opening in a buildingand be permanent-" 1y "secured thereto. "The fr'aine has a'sa'shj removably mounted therein including upper and lower sections which may readily be removed for cleaning. I also provide a screen adaptedto replace the '1owersection of the sash duringfwarm weather. I make specialpr'ovis'ions' for sealingthe joints between-the sash and the frame and between the twos'ections of the sash. I also pro: vid'eremo'v'able retainer strips for holding the panes in the sash sections whereby replacement of a broken pane may be effected: by the average hbusehcl'der'without s'p'eciahtools. The frame comprises a head rail, side rails and bottom ra'ils' having channels'on their inner faces. The sash section's comprise top, side and bottom rails 'of ,charinelbar having sealing'fianges" adapted to cooperate with'the channels the frame rails. The rails of the frame an'd'= sash are preferably cut from stockextruded from" aluminum or other light metal, and I provide novel means for assem bling them rapidly and at 'lowcost.
A complete understanding of the invention may be obtainedfrom the following detailed description which refers to the accompanying drawings'illustra'ting a preferred embodiment. In the drawings, Y

Referring in detail to the drawings and, for
the present, to Figures 1 through 6, the storm window of my'invention comprises a frame ill thereal'ong and the bottom rail I6 has a sealing" channel 19 formed at its upper edge, The head rail and siderails are grooved as at 20 toincrease their rigidity and improvetheir appearance,
- 'The'side railsare notched or mortised as at 2| to receive the ends of the head rail and the rails are bolted together with the inner corners of the head rail overlying the inner corners of the side rails. A finish plate 22 is secured over the adjacent ends of the head and side rails to conceal the jointf The lower ends of the siderails are bolted tothe ends of the bottom rail in overlapping relation, the sealing channels 18 of the side rails being cut away to the extent necessary to permit assembly of the rails in this. relation. The bottom rail has ventilating louvers 23 formed therein. A slide 24 movable between guides 25- formed on the inner face of the-bottomrailmay be adjusted to overlie the louvers to the desired extent, thus affording easy control OfgilhBfiIIlOllIltl of ventilation.
The width of the rails of the frame beyond opening which will accommodate a frame of given dimensions: 1
The frame lll'is provided with'leaf springs 21 of H shape shown in' detail in Figure 3 adapted to' e'rigage the sides of the upper sash section 12. The'vframe' is also provided with looking levers 28 and. 2fpivoted thereto 'for retaining the lower sash section l3 in'position'. "The levers are shown in detailin Fi ures 4' and'5. The springs 27 and levers 2'8 and 29 are secured toa flange 30 extending outwardly from the outer'wa'l'l ofthesealing channels [8;
The sash sections l2 and13 are'of generally similar"'construction"but; each. will be described separatelyin detail. The upper section-112, as shown in Figures '7 throughil2l 'omprisesia top rail 3 l; side rails 32 and. abottomv or meeting rail 33 composed of channelbar's" assembled to. form axrctangiilar frame for a glass. pane 34. The section's'ilof; .the' channelibars are shown clearly inLFiguresB through 10.. 'All the bars have a web 35 and flanges 36 and 31. Secondaryflanges. 38 extend inwardly from the flanges136 and 31;A flange;39textendsinwardly from the flange 36 to provide a seat for the pane 34. .The' web 35 of the-several channel'bars is slotted on its inner side" as at 40 to accommodate "a retaining strip 4| "having the generallshape' of'a Z bar' in section; It: will be observed inFiguresifi'through 10 that the slot 40 receives one flange of the retain-1. ing strip whilethe other; extends inwardly of the edge of the pane toretain itgagainstthe flange 39. The outer edge of the web of the strip has a ad o a i eremoval off. the strip y a prying instrument such as1 a-;screwdriver. A sealing andcushioning gasket strip '42 ofcork or the like is disposed L between the retaining strip e 1.th nan a 'r e channel bars of --whi'ch the rails of the sash section are formedare beveled at-their ends.
and ;are secured 'togetherby angle brackets 43'. one of which is shown in Figure l2.- These brackets have legs disposed; at right angles and notched on opposite sidessas at144.- The legsof the angles extend into the slots in the channel bars defined 'by the web 35, the flanges 3 6 and 31 and the secondaryflanges 38. When the bars ha e been assembled with the. angle; brack ts: in
this manner, the secondary flanges are deformed by suitable dies to cause the metal thereof to flow into the notches 44 to a limited extent, thereby providing a positive mechanical lock which holds the rails of the sash section permanentlyand rigidly in assemble'drel'ation. The bar forming the top rail 3| has a stiffening flange 45. The bars forming the side rails have a sealing flange 46 of angle section. The bar forming the bottom rail 33 has an outer sealing flange 41 and an inner sealing flange 41a.
The upper sash'section is dimensioned so that when'it'is placed against the inner face of the frame, the sealing flanges 46 on the side rails 32 will be in alinement with the channels l8 on the side rails of the frame. When the sash section is-thu'spositioned, it may easily be pushed upwardly until the top railenters the channel I! on the headrail of. the frame after which the lower portion ofthe sash;section may be moved-outwardlyuntil the flanges 46 enterthechannels l8 throughout the full length'of the formen- The springs 21 tend to urge the sash section away from the frame but it is held in place against the spring pressure by -the lower sash section 13 when put inplace and locked by the levers 28, as'will be apparent from the detailed description-thereof given herebelow. It will be evident from thedescription sofar. that the top rail '3 l of the upper sash section-makes tight sealing engagement with the channel I1 on the head rail of the frame and that the sealing flanges 46 on the side rails of the sash section similarly have tight sealing engagement with-the channels 8' on the side railsof the frame;-; r J :p
The lowersash section l3,shown in Figures 13 through 1'7is generally similar to the upper'section l2 in that it is composed of. a top rail 48, side rails; 49,,and a bottom rail'50. .Theside rails 49 and the bottom rail 5fl-are composed of channel bars'of the same section as the side rails 32 of the upper sash section. The top rail 48 is composed of a channel bar similar to that forming the top, rai1 3| of the upper sash section exceptqthat the formerhas an upwardly extending flange 5| in stead of the downwardly extending flange 45. The rails of the upper sashsection are secured together by; angle brackets43 and a glass pane 52 is seated therein and secured by retainer strips 4| in the manner already-described. s When the upper sash section has; been installed asexplained above, the lower'section may be put in place by disposing the flange 31 of the top rail 48 against the flange 36 of the bottom rail 33 of the upper sash section. The lower portion of the lower sash section maythen beswung inwardly until the sealing flanges 46 on the side and bottom rails enter the channels [8 in the side rails of 'the frame and the channel IS ,in the bottom rail thereof. The levers 29-may'then be turned down to hold the lower sash section inyposition. As shown in, Figure 18, the flange 5| of the top rail of the lower, sash section makes sealing engage ment with the flange 4'|a'of the bottom rail of the upper section. ,Similarly, the flange "or the bottom railof the upper section makes a tight joint with the web 35 of the'channel bar forming the top rail of the lower section. This web has a rabbet 53 to receive the flange 41, the depth of the rabbet being less than the thickness of the flange whereby the latter overhangs so as to permit free drainage, of rain water; Since the several rails of the sash sections are made of extruded stock which may be kept within very close dimensional tolerances, a precision fit of the meeting ing the sealing relation of the flanges 46 of the upper section with the channels 18 on the frame. Figures 19 through 23 show a screen 54 adapted to replace the lower sash section [3. The screen comprises a frame including a top rail 55, side rails 56 and a bottom rail 51 held in assembled relation by means of angle brackets 43 in the same manner as the sash sections. The top rail 55 is formed from channel bar generally similar to that used for the top rail 48 of the lower sash section except that it does not have the sealing flange 5| and has a channel 58 on the inner side thereof adapted to receive the edge of a panel 59 of wire mesh and a binder rod 60. The side rails 56 and bottom rail 51 are composed of a channel bar similar to that used for the side rails 32 and 49 except that they are provided with the channel 58 instead of the flanges for the glass pane to seat against. When the rails 55, 56 and 51 have been assembled, the screen may be completed by laying the panel of wire mesh thereon and pressing the binder rods 60 into the channels 58. It will be understood that the edges of the panel lap the channel 58 so as to be tightly held by friction when the rods are pressed home. The mesh panel may be replaced whenever necessary by prying out the rods 60. It will be apparent that the screen 54 has means for tightly sealing all joints between it, the frame and the upper sash section H, thereby precluding the entry of even the smallest insects.
The storm window of my invention, as will be evident from the foregoing, has numerous advantages over storm windows as constructed heretofore. In the first place, the frame and sash sections are all metal, except for the glass panes, thereby eliminating warpage, shrinkage or the like, and permitting manufacture to desired dimensions within small tolerances. In addition, the all-metal construction has a long life, showing little or no deterioration after extended use. The frame is factory-made in proper sizes so there is no cutting or fitting on the job. The wide lap of the frame over the edges of the window opening permits a single size of frame to be tightly fitted to window openings in a range of sizes; thus a few stock sizes of frames can be adapted for practically all standard sizes of windows. The fabrication of frames and sash sections to special order is but a simple matter, however, since the only variable is the length of the side, top and bottom rails and the size of the panes.
The angle bracket used to connect the rails of the sash section provides a rigid construction which may be assembled quickly and easily. The rigidity of the resulting frame protects the glass pane from twisting stress. The removable retainer strips make it possible to replace broken glass very easily and the gasket strips prevent leakage of air around the edges of the panes. The joints between the frame and sash sections are closed by baffle or labyrinth seals, reducing infiltration to a minimum, providing effective Weatherstripping of the sash.
The invention may be applied to buildings of any construction, i. e., frame, brick, stone or stucco. Finally, my construction permits easy removal and replacement of the sash sections for cleaning and replacement of the lower sash by 6 a screen during warm weather. Accurately controlled ventilation is obtainable by the slide 24 when both sash sections are in place.
Although I have illustrated and described but a preferred embodiment of the invention, it will be recognized that changes in the details and arrangement disclosed may be made without departing from the spirit of the invention or the scope of the appended claim.
In the combination of a frame with a plurality of glazed sash panels mounted therein in substantially coplanar abutting relationship, the sash panels being in slidable engagement with the sides of the frame and being removable from the frame in a direction normal to the plane of the frame, the improvement comprising a pair of opposite parallel side members of the frame each in the form of an integral length of extruded metal having a first flange extending parallel to the plane of the frame and two other flanges projecting from one side of the first flange normal to the plane of the frame and forming a channel therebetween, said first flange having a flat surface of substantial area on said one side between the outer edge of the, first flange and the nearer of the other two flanges, and a pair of opposite parallel side members of each sash panel slidably engageable with the respective frame members and also each in the form of an integral length of extruded metal, each of said sash panel members having a flat portion of substantial are-a slidably bearing against said flat surface of the first of said flanges of the adjacent frame member, and having a flange of substantially U-shaped cross section extending around both sides of one and along one side of the other of the said other two flanges of the adjacent frame member, with the U-shaped flanges of the sash panels extending from and between the front and rear planes of the sash panels and with the outer edges of the interlocking flanges of the sash panels and frames spaced from any sliding contact during relative movement of the sash panels in the frame, whereby the said flanged frame and sash panel members form a rigid and weather-tight window structure with the wear distributed along the sides of the flanges to increase the life of the structure.
