Application filed February 20, 1929.

To all {UV/E0772. 2 2 may con c-cm:

ing construction, and particularly to window sashes, screen sashesand shutters, and more especially to an improved window frame for the support for all three of such closures.

An object of this invention is to provide a sheet metal window frame, constructed to hingedly support a plurality of closures, such as a window sash, screen and shutter, there being means cooperating between the window sash and the window frame acting to lock the window sash in position and at the same time constituting a weather strip.

Another object oil the invention is to provide a window sash having guides for the support of a plurality of counter-balanced auxiliary sashes, for closing the opening through the sash.

A further object or the invention consists in the provision of a plurality of auxiliary sashes, countor-balanced in pairs and slidable in guides of a window sash, each pair ot' auxiliary sashes forming a closure, so that when the auxiliary sashes or". all the pairs closed, intermediate spaces are provided to insure keeping; out the cold air, and preventing the escape of the warn'i air. The auxiliary sashes of the various pairs thereof are adapted to be manipulated for ventilating purposes, as is disclosed in the variousdiagrammatic views of the drawing. A still further object 01. the invention is the provision of a sheet metal window frame having means 'for the reception of the window trim.

further object or the invention is the provision of means for latching; one oil. the closures, in combination with connections between such closure and another of said closures, so that when the first closure is locked,the second closure will be locked.

An additional object of the invention is the provision of a window frame constructed from sheet metal molding, adapted to form the side and end rails of the frame, in com- Serial No. 360,151.

bination with means for connecting the side and end pieces to provide a rigid structure to engage the window opening of the wall.

1V hile the desin'nand construction at present illustrated and set forth is deemed preferahle, it is obvious that as a result of a reduction of the invention to a more practical form for commercialpurposes, heinvention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and coinbinationol parts, as will be hereinafter set forth, shown in the drawings and claimed.

Referring more especially to these drawings, 1 designates the window frame, preferably constructed of sheet metal, as shown. The frame 1 comprises the top and bottom end pieces 2 and 3 and the vertical side pieces a and 5. These side and end pieces are designed to beconstructed from suitable sheet metal molding of the character illustratedin the drawings, and according to the size of window frame to be used. The side and end pieces may be cut from the molding according to the dimensions necessary to make window frames to it various proportions of openings and walls of buildings. The opposed walls of the side and end pieces of the window frame at the corners of the window frame as illustrated in Figure 8, are joined by spot-welds as indicated at 6. These spot-welds are constructed by first notching the ends of the flanges of the end pieces as indicated at 7, so as to receive the ends of the vertical side pieces, that is to say, the flanges atthe ends of the vertical naeaeaa side pieces. Right angle plates 8 are arranged adjacent the inner surface of the adjoining ends of the flanges of the side and end pieces, and by means of the spot-welds as indicated at 6, the side and end pieces are securely and rigidly joined. It is to be noted that when fittingthe ends of the flanges of the side pieces in the notches '2", the walls 9 of the side pieces engage the edges 10 at the ends of the top and bottom end pieces. In other words, the end portions of the top and bottom end pieces are bifurca'ted as indicated, so that the ends of the side pieces will fit the end pieces, whereby the walls 9 and 10 may engage, as shown clearly in Figure 8.

The .inner flanges of the side and end pieces of the window frame adjacent their edges are bent to form channels 11, which when the window frame is complete, form a marginal channel on the interior of the room, to receive the ordinary trim or woodwork 12, which surrounds the marginal portion of the window frame not only to assist in holding the frame in position, but also to present a neat appearance and a finish. The brickwork 13 about the marginal edge of the window opening of the wall extends partially into the window frame, as clearly indicated in Figures 2 and 3, so as to hold the frame in position. The channel portion of the inner flange of the window frame is immediately adjacent the brickwork, and by means of the trim, the frame is held in a rigid position.

The inner wall of the window frame or casement (which is engaged by the inner flange of the main window sash) is provided with an angular rabbet 13. The wall of the window frame (which is engaged by the window sash) is provided with a substantially ttshaped channel 14. The wall 15 of this channel 14 is deeper than the opposite wall, and the outer wall of the channel 15% at the bottom and one side of the window frame is provided with an angular recess or rabbet 16, the purpose of which will be hereinafter set forth.

Mounted in the window frame is a window sash 17, and the side and end pieces 18 and 19 are out from sheet metal tl-shaped or channelled molding, according to the de sired lengths, to fit various sizes of window frames. The top and bottom end pieces are bifurcated at 20, in a manner similar to the bifurcation of thetop and bottom end pieces of the frame, to receive the ends of the flanges of the side pieces as indicated in Figure 1. In fact, the channel side pieces engage in the bifurcations, and by means of angle pieces 21, which are spot-welded in place, the side and end pieces of the window sash are securely and rigidly connected, thereby providing a rigid window sash.

The outer flange of the window sash is designed to engagethe wall 15 of the ll-shaped channel of the window frame, and it is to;

= engages the angular rabbet 16 of the wall 15, in order to assist in holding the window sash in position. One of the side portions of the inner flange oi the window sash is hingedly connected at 22 to the window frame, so. that the window sash can swing inwardly, when it is desired to have access to the screen sash or frame and the shutter.

Mounted adjacent the innerface or" the outer flange of the window sash, that is to say, the bottom portion and one side portion thereof, is a right angle locking member 23.

This locking member 23, which also con- 'stitutes weather strip is provided with arcuate slots 24, receiving guide pins 25. However, one of the guide pins :25 is capable of rotating and is provided with an arm 26 which is pivotally connected to the locking member or weather strip as at 27, so that when rocking the rotatable guide pin, the locking member or weather strip may be moved to. annnloclred position or to a locked position. ld hen the locking member or weather strip is-in locked position, it protrudes beyond the angular recess 16, so as to protrude further into the channel .14, there by preventing the window sash from being opened, particularly from the exterior, there is no way of reaching the rotatable pin, for the purpose or operating the same. The inner end of the rocking pin is pro vided with a transversehand piece 28, to be grasped by the hand oi an operator so as to rotate the'pin, for moving the locking or weather strip into locked and unlocked position.

Secured to the wall. 29 of the window sash is a plurality of parallel frames 30, the side and end pieces of which are ll-shaped, therefore, are provided with channels 31. Preferably there are six of these channelled frames, though they may be more or less, and these frames are connected to the wall 29 of the sash in pairs. The frames of the inner pair are spaced from the intermediate pair, while the frames of the outerpair are spaced from the opposite side of the intermediate pair. Upper and lower pane or glass receiving auxiliary sashes 32 and 33 are mounted in the inner pair of channel frames of the dominant sash l7, and these auxiliary sash frames are constructed from channel members, so as to receive the window panes or glasses 3a and 35- These auxiliary sashes have their: meeting rails provided with interengaging flange connections 36, whereby when said auxiliary sashes are closed, a substantially air-tight joint is provided, Furthermore, this joint will assist materially in holding the auxiliary sashes rigid. Mounted in the outerpair oi hannel frames of the dominant sash. 1'? are upper and lower pane or glass receiving auxiliary sashes 37 and 38, which are similar in construction to those areviously de scribed, and their meeting rails are provided with inter-engaging flange eomiections Mounted in the intermediate pair of channel frames of the dominant sash are upper and lower glass or pane receiving auxiliary sashes 40 and 41, the meeting. rails Of which also have inter-engaging flange connections 42. It will be noted that by the provision of the three sets or pairs of channel. frames with their respective upper and lower MUL- iliary sashes, intermediate air s ices and a0 44- are provided, acting, as cushions for the exterior air and the interior air oi the room. The lower rail of the inner sash provided with suitable hand grips h). whereby the lower sash 35 may be raised. it will be noted that in Figure 13, the meeting rails of the various auxiliary sashes adjoin each other in a plane, angular across the domi nant window sash, that is to say, in a direction outwardly and upwardly] it will be noted that when the auviliar sashes are reversed in their positions. in fact" the lower auxiliary sashes moved into their upper positions-and the upper auxiliary sashes to lowered positions, as shown in the various diagrammatic views. the interior of the room can be iFlJiIllfiiQifl, (swing to the spaces between the adjacent hcriziontal ra r," o'l said sashes r m shown in the diagraiw matic Figure 5, the lower inner auxilia sh is aised and the outer upper auxiliaii' sash is lowered, theretore. the dead air spam between the inner auxiliary sashes and the intermediate auxiliary sashes is di owing to the passages resultin; ajacent rails of said auitil air space between the ou and the intermediate :1 ise destroyed, by reversing the po the outer upper and lower 'lia If desired, the various an be suspended in re ister with: above and below allot the aux the other through the met o'l; cord e5 which passes over a pulley outer upper and lower an airy connected and are counter-ha]ancefl o e against the other by means ot a sash co d 4?, which passes over a pulley "he intermediate upper and lower aurriliar ashes are also connected and COllIl'iClY-Gtllfi ed hv a sash cord 49 passing over the pulley Fl By this arrangement oil coi'inecting counter-balancii the aura iary sashes (or that shown in F3511 es 5.

.54, and they are counter-balanced thereby.

T he upper and lower intermediate auxiliary sashes are connected and counter-balanced by means of the sash cord passing over a pulley '56. This arrangement permits the various auxiliary sashes to be moved to different positions to those assumed by the s: shes shown in Figure 2, thereby enabling a different arrangement of ventilation. It is obvious that the auxiliary sashes may be connected and counterbalanced in any other suitable manner. In other words, the inven tion, particularly pertaining to the auxiliary sashes is not to be limited in any way in so far as the connections and counter-balancing of the sashes are concerned. The manner of counter-balancing the auxiliary sashes, and the arrangement of them in pairs, so as to provide the intermediate air spaces constitute an improvement over the construction and arrangement of dominant sashes, such as shown in the co-pending application. filed August 2nd, 191.9, Serial Number 314C910 in the name of George lV. Lancaster, and which application has matured into patent, issued December 7, 1920, Patent Number 1,361.,1

The marginal rabbet or channel. 57 (which is angular in cross section) receives a screen frame 58. Adjacent the upper part of the channel or rabbet 57, a pair of suspension or hinged hooks 59 is secured preferably by spot-welding, though it is obvious that they may be otherwise connected. These hooks are in the form of plates bent upon themselves, the bends thereof acting as supporting hooks 60. he plates forming the suspension or hinge hookshave their upper parts recessed as indicated at 61 so that when the plates are bent to form the hooks these recesses will be positioned adjacent the sides of the hook, thereby permitting the bends proper of the plates to protrude upwardly beyond the recesses to form lugs 62.

The screen frame is also designed to be constructed of sheetmetal, and. secured in any suitable manner to the upper rail of the screen frame, preferably by spot-welding, are hanger plates 63. These hanger plates are bent to form theupwardly extending parts 64 which are provided with slots 65 which engage the books of the plates 59,

thereby hingedly mounting the screen frame. It will be noted that when the screen frame is swung outwardly i1;- niay be easily detached from the hook. Hingedly connected at 67 to the upper part of the outer portion of the window frame is a shutare angle plates or hooks 68, which are en 'aged by the lower portion of the screen frame 58, when the shutter and the screen if 'anie are closed. However, when the shut ter is swung open the screenfrarne will also be moved to an open position. When shutter swung open far enough, the s reen frame will disengage from the angle plates or hoo s 68 owing to the different arcuate movements of the shutter and the screen frame. In other words, the screen frame and the shutter are mounted toinove through converging arcs, therefore, when the shutter is moved to an open position far enough the screen frame will disengage from the angle plates or hooks 68. When the shutter is moved to an open position far enough to per halt the screen frame to disengage, the screen frame may be moved inwardly again and fastened, and in such a case the shutter may be supported in an open position by means of the brace 69 shown in Figure 1.

it is obvious that when it is necessary to close the shutter, the screen frame must be swung open again until its lower end is in a position to engage the angular plates or hooks 68, and then the brace 69 is disconnected from the exterior of the window frame, after which the screen frame and the shutter may be moved inwardly together. Secured at 70 to the lower part of the window frame is a keeper 71. This keeper comprises a plate, which has an upwardly ex tending flange 72 disposed at an angle to the horizontal position of the lower part of the window frame. This flange 72 is formed by bending the plate upon itself as shown in the detail view in Figure 10 of the drawing. A latch is pivotally secured by means. of a screw 73, to the lower rail of the screen frame, and this latch has a handle portion T l, and a keeper engaging part 75, which is curved as shown.

This latch is constructed from a single piece of sheet metal as disclosed in the drawings. The keeper engaging part, when the latch is swung in one direction, is designed to engage the inclined flange 72, thereby latching the screen in a closed position, and when so closed the shutter will be held in a closed position owing to theangular plates or hooks 68. When the latch is moved in the opposite direction, thekeeper engaging part Figure 12, the main sash 80, which is similar in some respects to the main sash heretofore described, has its auxiliary sashes arranged in spaced relations .to prov de the air spaces or pockets heretofore rel l to. inese auxiliary sashes are also inter-locked as shown at 81, and are niiininted in guides 82. Additional guides 83, 84. and are adjacent the guides in which the auxiliary sashes are mounted, and mounted in the guides 83, Eli; and85 are rods 86, 8'7 and 88 and connecting the rods 86, 87 and 88 with the upper parts of the upper auxiliary sashes are ropes or cables 89. Carried by the side rails of the lower auxiliary sashes are projecting a ms 90, 91 and 92. Certain. of the flanges of the guides for the rods 86, 8?- and 88 having openings 94, which are adjacent the arms 90, 91 and 9:2. The cables which connect to the rods pass over the pulleys 95 which are journaled in any suitable manner, as shown, in the channel of the upper part of the main sash, and are connected to the upper ends ot the upper auxiliary sashes. It is obvious that by removing the lower rod 86 from its guides through the lowermost notches of one of the flanges of the guides for the rod and in setting it through the succeeding notch or notches, the rod 86 may be disposed under the arms 91, thereby lowering the upper inner auxiliary sash, in tact lowering it a distance substantially equal to the distance between the pins 91 and the bottom ot the main sash, thereby breaking the air pocket between the inner sashes and the intermediate sashes. Then the rod 86 is disposed in engagement with the arms 91. it is obvious that the lower inner auxiliary sash may be adj usted, by applying pressure on the rod 86 under the pins 91 rai. ing the lower inner auxiliary sash, and when raised, the upper inner auxiliary sash will be lowered correspondingly. However, when raising the lower sash by engaging the rod 86 with the arms 91 ot' the inner lower sash, the upper inner auxiliary sash may be lowered to an open position for a distance equal to the space between the arms 91 and the bottom of the main sash. Should the inner lower auxiliary sash be moved by applying upward pressure on the rod 86, when engaged under the arms 91. the upper inner auxiliary sash may be lowered for its full movement, while the inner lower sash will be raised to a position wi h its upper edge spaced a distance from the upper railof the main sash substantially equal to the distance between the arm 91 and the arm 90.

After manipulating the inner auxiliary upper and lower sashes, the intermediate auxiliary upper and lower sashes may be likewise adjusted. If desired, the rod 86 or the rod 87 or the rod may be moved to engage any of their respective arms 90, 91 and 92, in order to raise and lower the inner auxiliary sashes. In other words, said auxiliary sashes are capable of adjustments in yariable positions relatiie to each other, or are capable ol adjustments to corresponding positions. It is obvious that this construction of the auxiliary sashes is equally as well adapted for use in connection with the window construction shown in Figures 1 and 2. In fact, the main sash shown in Figure 12 is similar in every respect to the main sash shown in Figures 1 and2, with the exception that the sash in Figure 12 is equipped with different auxiliary sashes, and it is obvious that the construction in Figure "12 can be used in Figure 1 or in Figure 2.

In Figure 13, the auxiliary sashes are arranged in stepped relation-similar to the construction shown in the patentto George 1V. Lancaster 01 December 7. 1920, Patent No. 1,361,163, but in the present instance, the upper and lower auxiliary sashes are capable of adjustments in variable positions relative to each other. in a manner similar to the adjustments oi": the auxiliary sashes in Figure The auxiliary sashes 96, 97, 98 and 99 in Figure 13 have inter-locked connections 100, and the two intermediate auxiliary sashes in Figure 13 are counter-balanced, by means of the cable or rope 101, passing over the pulley 102, which is journalled in the upper part of the main sash in any suit able manner. The main sash in Figure 13 is PZ'OVlClGtl with guides 103 which are similar to the guides of the sash in Figure 12.

liflounted in the guides 10S normally in thelower portion thereof is a sash. adjusting rod 10%, which is connected to and counter-balanced with the uppermost auxiliary sash 99 by means oi" the cable or rope 105, which passes over the pulleys 106, which are jour nailed in the upper part of the main sash in any suitable manner. It is to be observed that by removing the adjusting rod 104 from its guides. bypassing through any one of the notches 104' of certain oi the flanges of the guides 10 and placing it under either one ot the upper lateral arms 108 of the lower auxiliary sash. the upper auxiliary sash may be adjusted. in variable positions with relation to the lower auxiliary sash. By causing the rod 101- to engage under the lower arms .109 of the lower auxiliary sash, the lower and upper auxiliar g sashes may be opened correspondingly. ilia'iy sashes shown'in Figures 1, 2, 12and 13 extend the entire width of the dominant or main sash. rioweyer, each of these auxiliary sashes may be made upin panels. such shown in Figures 1 1, 15 and 16. In fact, the auxiliary sashes are in the form of chan nel irons, shown in Figure 16 to receive The various auxthe pane of glass 110. These channel frames:

have channel guides 111,'near one end 01 ment.

the frame to receive the panes of glass 112- and 113. The channel frame at one end is cut away or slotted as shown at 114; so that the pane of glass 112 may be easily removed for repair or for the insertion of a new pane. The channel frame is also provided with spaced vertical strips 115. The other end of the channel frame has a vertical cut away portion or slot 116, through which the panes oi glass 110 and 113 may be inserted, or removed,in other words removed for repairs. or for the insertion of new panes. It will be noted that the adjacent edges of the panes 110 and 113 engage between the vertical strips 115 thereby holding them in position. The panes of glass are designed to engagethe channels of the channel frames frictionally, in order'to remain in position.
