14 Claims.

This invention relates to supplemental metallic window units, that is to say to additional units for incorporation in regular Window structures of a permanent type, and characterized by having sliding glazed storm sashes for winter use, and sliding screen sashes for summer use, the present application being a division of a U. S. Patent #2,295,685, granted to-me on September 15, 1942.

Amongst the objects of my invention are to enable the component parts of a supplemental window unit of the kind referred to to be assembled in a permanent window structure without requiring the aid of any special tools, and without the need of screws, bolts or otherfastening devices to subsequently hold them in place; and to make possible the ready and quick interchange of the glazed and screensashes without necessitating the removal of other parts of such unit.

Still another object of my invention is to attain the foregoing advantages in a supplemental window unit which is simple in constructiomand whereof the sash frameparts and the sash guides lend themselves to expeditious manufacture from sheet metal at relatively small cost.

Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein Fig. 1 shows the outside elevation of a metallic window structure with a supplemental or auxiliary unit conveniently embodying my invention.

Fig. 2 is a vertical sectional view of the organization taken as indicated by the angled arrows IIII in Fig. 1.

Fig. 3 is a horizontal section taken as indicated by the angled arrows III-HI in Figs. 1 and 2. I

Fig. 4 is abroken-out perspective view of one of the sash guide elements of my improved supplemental window unit.

Fig. 5 is a view corresponding to Fig. 2 with screen sashes substituted for the glazed sashes shown in the latter illustration.

Fig. 6 is a fragmentary sectional view taken cal with that featured in the co-pending applicationhereinbefore referred to, the sides or jambs of its frame being indicated at l, the head or lintel at 2, and the sill at 3, these being all of hollow formation. As seen in Fig. 3, the jambs I have their inner faces medially recessed longitudinally as at 4 and are provided at the outside and inside comers with box beads 5 and 6. Secured centrally of the jambs l by means of screws 1 are parting strips 8 of U shaped cross sectional configuration whereof the longitudinal flangessserve as guides for upper and lower sliding sashes 9 and llLthe lintel 2 of the'window frame being longitudinally recessed as at II to receive the top edge of the' upper sash, and the sloping surface l2 of the sill being stepped as at l3 for engagement by the bottom rail of the lower sash Hi, all as shown in Fig. 2.

The supplemental window unit, with which the present invention is more especially concerned, includes a pair of auxiliary jamb or sash guide strips l5 whereof one is shown in perspective in Fig. 4. Although these strips may-be otherwise portioned that their central ridges l6 frictionally as indicated by the angled arrows VI-VI in I venience of exemplifying my invention is identi-- fit over the outer box beads 5 on the jambs l of the main or permanent window, which beads extend inwardly of the window opening as shown in Fig. 3. The sides of the central ridges l6 of each auxiliary jamb strip l5 are depressed inwardly from opposite sides to form stop shoulders I1 which bear against the comer beads 5 of the corresponding main jambs l and thus determine the position of said strips in the main window structure. The outer walls l8a and Ma of the reversely positioned outer ridges I8 and I9 of each jamb strip l5 provide, in conjunction with the central ridge l6, parallel sash guiding grooves 20 and 2|. From Figs; 2 and 4 it is to be noted that the grooved side wall |8a of the strip l5 extends downwardly to near the middle of the main window structure,'and that the grooved side wall Illa extends upwardly to the same extent. The purpose served bythis construction will be explained later on herein.

My improved supplemental window unit further includes upper and lower glazed sliding sashes 24 and 25 to correspond with those of the main window. As shown in Figs. 2 and 3, the frame of the upper sash comprises a top bar 26 and side bars 21 of Z cross section, and a bottom bar 28 of W cross section whereof the outer trough isdisposed in the plane of the other three bars, said bars being all permanently united at corners preferably by welding. Set into the frame of the upper sash 24 is a glass pane 29 whereof; the edges are enveloped by compressible weathering 30 which may be of felt or rubber. The laterally projecting flanges of the side bars of the upper sash frame are sheathed by conformative strips 3| fashioned from relatively thin non-corroding metal. As shown in Fig. 3, the sheathed projecting side flanges of the upper sash frame 24 are snugly engaged within the corresponding grooves or guideways 20 of the auxiliary jamb strips I and the sheathing strips are extended inwardly of the window frame at the outer face of the upper sash to act as retainers for the glass pane 29. The top bar 26 of the upper sash is likewise provided with a sheathing strip 32 which is like the strips on the side bars except for being fashioned to provide a groove for the retainment of a compressible hollow sealing strip 33 of rubber or the like to bear against the under-side of the lintel 2 of the main window frame, as shown in Fig. 2. The projecting flanges of the top and side bars are apertured at intervals of their length as instanced at 35 in Fig. 2 and the metal of the sheathing strips is depressed inwardly from -opposite sides of said flanges into these apertures. In this simple way it will be seen that the sheathing strips are effectively secured without the aid of additional fastening means. To the bottom bar 28 of the upper sash 24 is suitably secured a strip 36 of thin non-corroding spring sheet metal of which a free edge portion 36a extends downward into the inner trough of said bar.

The frame of the lower sash 25 likewise has top and side bars 31 and 38 of Z cross section which are'reversed in position with respect to the corresponding bars of the upper sash. The bottom bar 39 of the lower sash 25 is also of 2 cross section, but reversed in position with respect to the other bars 31 and 38 of said sash, said several bars being permanently united at corners preferably by welding like those of the upper sash. The side bars of the lower sash are similarly provided with sheathing strips 49 of noncorrosive metal which are similarly secured to the outstanding flanges of said bars, said flanges extending respectively into the guide grooves 2| of the auxiliary jamb strips |5 as shown in Fig. 3. The sheathing strip 4| on the top cross bar 31 of the lower sash 25 is extended outwardly as shown in Fig. 2 and then downwardly as at 42 to cooperate with the free spring portion 36a of the strip 36 on the bottom rail 28 of the upper sash 24, thereby to-form a weather-seal at that region when the sashes are in closed position. The sheathing strip 43 on the bottom cross bar 39 of the lower sash 25 is fashioned to provide a longitudinal recess for the retainment of a compressible hollow packing strip 45 of rubber or the like which is adapted to bear weather-tight against the top surface of the sill |2 of the main window structure. As shown, the sheathing strips 40 and 4| on the top and side bars 31 and 38 are extended inwardly at the inside face of the sash 25 and the strip 43 on the bottom bar 39 extends inwardly at the outside face of said sash to retain the glass pane 46. While the outer walls |8a and H311 of the grooves 28 and 2| in the auxiliary jamb strips l5 exert frictional pressure on the side flanges of the two sashes 24 and 25, such pressure is not sufiicient to hold the sashes in shifted position. I have accordingly provided the sashes respectively with suitable catches 41 and 48 whereof the slide bolts are adapted to respectively engage suitably allocated openings 49 and 50 in the auxiliary jamb strips 15. Due to the interruption of the guide grooves 20 and 2| in 5 the auxiliary jamb strips |5 approximately midway of the height of the window, as hereinbefore pointed out, it is possible to remove the upper sash 24 from below and the lower sash 25 from above, the bottom and top ends of the side walls of the grooves being bent outwardly somewhat as at I8b and |9b in Fig. 4 to facilitate such removal. In this connection, it is to be noted from Fig. 3 that the width of the two sashes 24 and 25 is such that the auxiliary jamb strips |5 are held in place by them, as a consequence of which,

the component parts of the supplemental window,

unit can be readily and quickly installed or removed from the main window structure.

The provision made for the ready removal of the glazed sashes 24 and also makes possible the ready substitution of upper and lower sliding screen sashe such as shown at 54 and 55 in Figs. 5-8. The frame of the upper screen sash 54, see Figs. 5 and 7, has top, bottom and side bars 25 56, 51 and 58 all formed to hollow channel cross sectional configuration with their hollows facing outward and with their outstanding flanges in a common plane, the flanges of the side bars 58 extending into the guide grooves 20 in the auxiliary jamb strips I5. Stretched across the opening of the upper screen sash frame is a sheet of wire mesh, 59 which is held in place by a clamp frame 60 whereof the bars are of U shaped cross sectional configuration, the latter frame being inserted, flange edges foremost, into the hollows of the main frame with the margins of the screening 59 engaged as clearly shown in Figs. 5 and 7. The outstanding flanges of the several bars of the main frame of the sash 54 are sheathed by strips 6|, 62 and 63 of non-corroding metal which are extended inwardly to overlap the corresponding bars of the clamp frame 60 thereby to hold the latter in place. The main frame of the lower screen sash 55 differs from the corresponding frame of the upper screen sash 54 in that its top, bottom and side bars 64, 65 and 66 are of L cross sectional configuration with outstanding flanges in a common plane whereof those at the side bars 66 fit into the guide grooves 2| of the auxiliary jamb strips |5 as shown in Fig. 8. The wire mesh 61 for the lower sash is clamped by a clamp frame 68 in a manner similar to that described of the upper screen sash 54 while sheathing strips 69, 10 and H of non-corroding metal serve to hold the clamp frame in place. Catches to hold the upper and lower screen sashes 54 and 55 in open or closed positions, the slide bolts of these catches being adapted to engage the same apertures 49 and 59 in the auxiliary jamb strips |5 which serve the catches 41 and 48 on the glazed sashes 24 and 25. In addition to the catches the lower screen sash 55 is fitted with handles as instanced at 14 in Fig. 6 for convenience of raising and lowering it.
