4 Claims.

This invention relates to improvements in storm windows, and, particularly, storm windows of the permanent self-storing type provided with an upper glazed sash and a sliding lower glazed sash which may be raised or stored during the summer-time to provide an opening in the lower half of the storm window frame; this opening may be screened with a sliding screened sash, which is adapted to be raised or stored during the winter-time, when the lower glazed sash is in use.

It is an advantage of storm windows made according to our invention that they may be made of extruded metal, preferably aluminum, having channel or box sections, thereby providing the permanence and strength of metal while being lightweight for shipping and handling and economical to produce. Storm windows made according to our invention are closely fitting, and may be produced for closer tolerances than has been heretofore possible with wood or metal storm windows of the self-storing type.

Because of the close fits necessary to obtain the desirable wind-tightness in storm windows, the so-called self-storing storm windows heretofore available have not satisfied this need. Such failure has been attributable largely to the fact that the prior art storm windows have had to be custom built, i, e. made on special order and fitted on the job in order to compensate or correct for the inevitable warped, misaligned and/or out-of-plumb construction inevitably found in the casings of windows in wood or masonry buildings. The carpentry or tinsmith work involved in fitting prior art wood or metal storm windows not only was very expensive but could not equal the close-tolerance precision construction of our windows. Our storm windows may be either cut and built to stock sizes in the factory or cut, in the factory, shipped, knocked-down, and assembled on or near the site of installation. Though our storm windows are preferably produced in stock sizes, such stock-size storm windows may be easily fitted to the wood or masonry casing of a window, despite the variations normally found in such window casings. This substantial advantage is obtained by providing an integral waste strip or flange around the frame of our storm windows.

It is another object and advantage of our storm windows that all the sliding sash may be easily removed for cleaning and such removal may be accomplished from inside the building on which the storm windows are fitted and permanently mounted. We accomplish this object by providing a tiltable sash which may receive the aforesaid sliding sashes and then may be tilted to project the bottom portions of said sliding sash into the room on which the window opens. Except when all said sliding sashes are in a position permitting such removal, the tiltable sash is locked.

It is another object and advantage of our invention to provide a novel adjustable pivot construction for the aforesaid tiltable sash which, after adjustment to fit the tiltable sash precisely in the frame, may then be permanently and securely locked in its adjusted position.

Another object of this invention is to provide a simple and convenient swingable handle construction permitting the sliding sash to be raised and lowered in the storm window frame.

A still further object of this invention is to provide a novel corner construction for the sliding sash providing a strong sash corner and simultaneously providing suflicient flexibility to prevent the glass carried thereby from being broken during use.

Other and further objects and advantages of this invention will be apparent from the following specification, claims, and drawings, in which Fig. 1 is an outside, front elevation of a storm window made according to our invention.

Fig. 2 is a side elevation of the structure shown in Fig. 1, but with the tiltable sash tilted inwardly and the sill of said sash swung open to a position permitting the sliding sashes carried thereby to be removed therefrom.

Fig. 11 is an enlarged sectional detail of the jamb of the window similar to Figs. 4 and but taken along the line II-II of Fig. 1.

Referring to the drawings, in which lik reference characters refer to like parts, our storm window is comprised of a frame, referred to generally by the reference character III. The frame In is comprised of a channeled lintel member II, channeled jamb members I2 and I3, and a sill member I4, all being preferably formed of extruded or rolled aluminum or like corrosionresistant metal to provid the strong and rigid box or channel sections disclosed in the several detail views and discussed below. Although the frame members II, I2, I3 and I4 are of a complex c'ross=section, they are formed economically and accurately either by the extrusion of molten aluminum or like metal through suitable extrusion dies or by rolling the section from coiled strip. Long lengths of such extruded stock may be cut with hack saws to window lengths, which window lengths may be routed in milling machines where modification of the cross-section in certain portions of such window lengths is required.

Specifically, the lintel H is cut to the window length required from extruded dee channeled stock of the cross-section shown in Fig. 3B of the drawings. Such lintel stock comprises, in crosssection, a body portion I I3 having sash-receiving channels III, H2, and H3 and an integral, outwardly-extending flange or waste-strip I I4 provided with the parallel break-off grooves II5. In the particular embodiment shown, the ends of the window lengths of the lintel stock are suitably mitered to form the mitered joints with the jambs I2 and I3, as shown.

The jambs I2 and I3 are each formed from lengths of extruded stock of the same cross-section, each such window length being mitered at one end to form the mitered joints with the lintel II and the preferred butt joints with the sill I4. Fig. 11 shows the unmodified cross-sections of the jambs in their upper portions I26 and I36. Equivalent cross-sections are shown by the combined areas of the portion of the jamb I2 and the portion of the tiltable sash jamb 22 shown in Fig. 4, or the combined areas of the portion of the jamb I2 and the tiltable sash jamb 22 shown in Fig. 5, or the combined areas of the portion of the jarnb I3 and the portion of the tiltable sash jamb 23 shown in Fig. 6. It will be noted that the configuration of all of said combined cross-sectional areas is identical. The jamb I2, therefore, is comprised of a box portion I20 having sash receiving channels I2I, I22, and I23 (indicated by dash reference lines in Figs. 4 and 5), and an integral flange of waste-strip I24 provided with parallel break-off grooves I25. The jamb I3 likewise has a box body I30 having sash receiving channels I3I, I32, and I33 and an integral waste-strip I34 provided with break-off grooves I35.

It should be noted that the waste strips I24 and I34 of the jams I2 and I3 occupy the same relative positions with respect to their sash receiving channels as the waste strip II4 of the lintel II occupies with respect to its sash-receiving channels, so that, when the lintel II and jambs I2 and I3 are joined with their respective sashreceiving channels in alignment, the waste strips I24, I I4, and I34 will form a continuous grooved fin around the top and sides of the frame III.

The walls defining the channels I22 and I23 of the jamb I2 are milled off or otherwise removed below the upper portion I26 in order to permit the frame jamb I2 to receive the jamb 22 of the tiltable sash 2D. The front wall I21 of the frame jamb channel I2I is also removed completely for a distance below the portion I23 in order to provide a stepped opening I28 for the sealing fin 28 of the tiltable sash jamb 22. Below the opening I28, only the rear of the Wall I21 is milled off, thereby providing a sealing fin I29 on the jamb I2. The jamb I3 is likewise milled to rovide an opening I38 and a sealing fin I39.

As is evident from the foregoing, the jambs I2 and I3 carry the tiltable sash 20, which is comprised of the channeled jambs 22 and 23 and the swingable sill 24, hinged on the jambs by means of the hinge straps 25 pivoted on the jambs 22 and 23. The jamb 22 may be milled out of a length of stock from which the jambs I2 and I3 are formed, but preferably the jamb 22 is cut from lengths of extruded stock having the crosssection of the jamb 22 as shown in Fig. 5. The jamb 22 has sliding sash-receiving channels 22I, 222, and 223 corresponding to the channels I2I, I22, and I23 of the ja'mb I2. The front wall 26 of the channel MI is extruded with a sealing fin 28, but except for the portion received in the opening I23 of the jamb I2, the fin 28 and the corresponding portion of the front wall 26 are milled off to permit the jamb 22 to fit and seat in the jamb I2 behind the sealing fin I29, as shown in Fig. 4. The tiltable sash jamb 23 is likewise provided with a sealing fin 29 adapted to be received in the opening I38 and is milled to seat behind the fin I39 of the jamb I3. The jamb 23, being of a similar configuration as jamb 22, is also provided with sash-receiving channels 23I, 232, and 233 which normally align with the corresponding channels I3I, I32, and I33 of the jamb I3.

The sash 20 is pivoted in the jambs I2 and I3 by means of the pivots 30. The tops of the jambs 22 and 23 are cut on an angle (which mates with the bottom of the upper portions I26 and I36 of the jambs I2 and I3) which permits the sash 20 to pivot only from an aligned position in the frame ID to a position in which the top of the sash 20 is swung outwardly and the bottom is swung inwardly, as shown in Fig. 2. The pivots 30 are comprised of hardened steel bushings 3| and pivot disks 32 provided with eccentric bosses 33, as shown in Fig. 6. The bushings 3I are received in suitable sockets drilled in the jambs I2 and I3 at the center of the steps of the openings I28 and I38. The pivot disks 32 are received in shallow sockets drilled in the back of the jambs 22 and 23. The edges of these sockets are then spun over to hold the pivot disks 32 rotatably in the sockets. I

Although the jambs I2, I3, 22, and 23 are preferably milled in suitable jigs to maintain uniformity, in actual production, variations from piece to piece and accumulation of deviations within permissible production tolerances will not insure that the tiltable sash 20 will always fit precisely in the frame I0, nor will the sliding sash receiving channels of the several jambs always align precisely immediately upon assembly, if the pivots 30 were not adjustable. To adjust the pivots 30 so that the sash 20 will fit and swing properly in the frame III, the pivot disks 32 are simply rotated in their sockets until the eccentricity of the bosses 33, rotating in the bushings 3I throws the sash 20 into proper position in the frame III.

To look the pivots 30 in their adjusted position, the pivot disks 32 are provided with a plurality of tabs 34 spaced about the periphery of the disks 32 so that in any adjusted position, at least one of the tabs will be located over a channel wall in the jamb carrying the disk. With the disk 32 rotated to its adjusted position, the tabs 34 are driven inwardly to rivet at least one in the deel iaS sections of metal provided by the channel wa With the sash 20 mounted in the jambs I2 and I3, the sliding glazed sashes 40 and 50 and the sliding screened sash 60 are slid into the channels of the jambs, the two glazed sashes being adjacent each other and the screened sash preferably being in the inner channels. The sill 24 may then be swung to its normal position closing the end of the jambs 22 and 23.

Figure 3 shows that the sill 24 is comprised of a length of extruded stock having a substantially box section and comprised of a sill portion 240 having a beveled sealing ridge 24I which, with the ridge 242, defines a screened sashreceiving channel 243. The sill portion 240 carries a dependent sealing fin 244 and a seating fin 245.

As a final assembly operation, the sill I4 is joined to the jambs I2 and I3. The sill I4 comprises a hollow body or box portion I40 having a slotadapted to receive a rubber sealing strip I M which engages the seating fin 245. The body portion I40 carries a sealing fin I42 which is engaged by the fin 244 of the sill 24. The body portion I40 also carries the integral waste strip I 44 provided with break-off grooves I45. The length of the extruded stock from which the sill I4 is cut is milled at the ends topermit the body portion I40 to be received between the jambs I2 and I3 and the waste strip I44 is notched, as shown in Fig. 1, to receive the ends of the jambs I2 and I3. The notches in the thin waste strip I44 are easily trimmed, as by filing, to compensate for any accumulation of manufacturing tolerance and to permit the sill I4 to seat firmly on the seating fin 245 of the sill 24.

The glazed sliding sash 40 is comprised of a frame of extruded metal stock 4I having a deep glass-receiving channel 42 in which the light 43 is received, being supported and sealed therein by means of the compressed rubber glazing channels 44. The glazed sliding sash 5B is similar to the sash 4!], except that this embodiment is shown with a bottom member 5| provided with a circular groove 52 adapted to receive a swinging handle III as may be seen in Figure 3; the member 5| is also provided with a weather-stripping groove 53 adapted toseat on the beveled ridge 24I of the sill 24 when the sash 50 is in its lowered position.

The screened sliding sash 60 is comprised of a frame of extruded stock having a cross-section as shown in Figs. 3A and 3B and provided with an inwardly opening channel SI in which the screening 62 may be locked by the locking wire 63. The bottom member of the frame of the sash 60 is also provided with a groove 64 adapted to receive a swinging handle III.

The handles I0 are hinged very simply in the sliding sashes. The handles I0 are punched out of extruded stock having a cross-section similar to that of the end views of the handles as shown in Figs. 3 and 3A. By punching out a center area bounded by the hinge pin portion II, the straps I2 and the grip portion I3, and simultaneously punching away an area bounded by the hinge pin portion, the straps I2 and the ends of the length of stock, a handle III, as shown in Fig. 8, is formed. To mount the handle in the sash, strap-receiving slots I4 are milled across the handle receiving grooves in the sashes. The hinge pin portions of the handles are then fitted in the receiving grooves and slid in from an end of the sash frame until the straps can fall in the slots I4; then the edges of the groove are peened over to lock the handles in place along the length of the groove. The handles are then free to swing from a dependent position, as shown in Fig. 3A to a raised position, as shown in Fig. 3.

To hold the several sashes frictionally in their raised positions and also to press the sashes against the forward walls of the sash-receiving channels in order to seal the tolerance allowed between the sash and channels and to prevent rattling, the portions of the sash frames sliding in the channels are grooved to receive leaf-spring wires 85, as shown in Figs. 4 and 5.

A very simple and novel corner construction for the sliding sashes is shown in Figs. 9 and 10. The frame members fit with a mitered joint, as shown, one member being drilled and countersunk to permit a screw to extend into the channel of the other frame member. The walls of the other member are slotted to receive a nut 5| which receives the screw 90. Tightening the screw 9i jams the mitered surfaces together and any tendency to spring the joint is resisted by the tensile strength of the screw. At the same time, the screw does not prevent one frame member from pivoting with respect to the other and thereby providing a flexible frame. It has been discovered that such a flexible frame reduces breakage of the glass which may be mounted in it due to sudden shocks, the rubber glazing strips permitting slight movement of the glass in the frame. The flexible corner construction permits the glass to flex and fiex other portions of the frame when one corner or portion of the frame is distorted. It has been found that a rigid corner construction will hold the glass rigidly and, thereby, increase the danger of glass breakage.

Operation Storm windows constructed and assembled as above described are preferably made up in stock sizes in which the width of the tilting sash 20 is somewhat less than the sash opening of the window on which it is to be mounted. This is to permit sash 28 to tilt into the room on which the room Window opens. The proportions of the several waste strips I24 and I34 are then such that their total width will exceed the width of the opening between the casing jambs in any stock window casings. The height of a storm window is also selected that the waste strips H4 and I44 will exceed the height of the opening between the sill and th lintel of the window casing. To fit the storm window, all that need be done is to break off the waste strips along the break-off grooves I I5, I25, I35, and I45 until waste strips fit against the blind stops of the casing. The Waste strips are then drilled and screwed to the casing.

When mounted and employed as a storm window to insulate the room window, the sliding sash 40 is raised and the sash 50 is lowered, and the screened sash is raised or stored, as shown in Figs. 1, 3A and 3B. For summer use, the sash 50 is simply raised or stored and the screened sash 50 is lowered. It will be noted that the parting line between the upper portions I26 and I36 of the jambs l2 and i3 and the tiltable sash 28 is above the bottom of the sash Thus, the height of each sliding sash being greater than the height of the upper portions of the jambs l2 and 53, when any one of the sashes is raised, the tiltable sash is automatically locked against tilting.

To remove the sliding sashes for washing, all sashes are lowered into the tiltable sash 20, care being taken to swing the handles it upwardly. The tiltable sash 29 may then be tilted and the sill 24 swung open, as shown in Fig. 2, to permit the sliding sashes to be removed into the room on which the window opens.
