2 Claims. (01320-45) This. invention relates to improvements in storm'window' frame construction and is particularlyadapted for use in storm window frames of the self-storing type which receive an upper glazed sash and a sliding lower glazed sash which may be raised or .stored' during the summertime 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, whenv the lower glazed sash is in use. This application is a continuation-in-part application with respect: to our co-pending application Serial N 0. 853756 for'Storm Window,. filed April 6, 1949, now U; S. Patent No. 2629.143" issued February 24,. 1953 and with respect to our pending application Serial No. 144,386 forStorm Window, filed- September 7, 1949, now U. I S. Patent No. 2,595,016 issued April 29, .1952.

It is an advantage of storm window frames made'according to our invention that theymay be made of extruded metal, preferably aluminum or stainless steel, having channel or box sections, thereby providing the permanence and strength-of metal while being light-weight for shipping and handling and economical tov produce. Storm windows made according to ourinvention are closely fitting, andmay 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 availablehave 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 primary windows in wood or masonrybuildings- The. carpentryantinsmith work involved in fitting prior art wood or metal storm windows not only was very expensive butcould not equal the close-tolerance precision construction of our windows. Our storm window frames 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 window frames are preferably produced in stock sizes, such stock-size frames may be easily fitted to the wood or masonry casing of a primary window, despite the variations normal 1y found in such. window casings. This substantial advantage, is obtained by providing an integral waste strip or flange around the outside of our storm window frames.

Other advantages of this invention will be apparent from examination of the following specification and the drawings in which:

Figure 1 is an outside front elevation'of a storm window frame made according to our invention.

Figure 2 isla side elevation of the structure shown in Figure l.

Figure 3 is an, enlarged sectional detail of the sill construction taken on the line 33 of Figure 1.

Figure 4 is an enlarged sectional detail of the frame jamb, taken along the line 6-4 of Figure 1.

Figure 5 is an enlarged sectional view of the frame lintel taken along the line 55 of Figure 1.

Referring to the drawings, in which like reference characters refer to like parts, our storm window frame is referred to generally by the reference character Ill. The frame is comprised of a channeled lintel member I I. channeled jamb members I2 and I3, and a' sill member I4, all being preferably formed of channels of stainless steel or like corrosion-resistant metal to provide the strong and rigid box or channel sections disclosed in the several detailviews and discussed below.v Although the, frame members II, I2, I3 and I 4 areof a complex cross-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 steel strip. Long lengths of such extruded. stockmay be cut to window lengths;

Specifically, the lintel II iscut to the window Width required from standard deep channeled stock of the cross-sectionshown, in Figure 5- of the. drawings. Such lintel stock comprises, in cross-section, a. body portion .I It having sash receivingchannels IIII'I, H2, and H3 and an integral, outwardly extending flange or wastestrip H4 provided with the parallel break-off grooves H5. 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 formed from lengths of standard stock of similar cross-section, the cross-section of the jamb- I2 being illustrated in Figure 4. Each jamb may comprise a box section I20 having sash receiving channels I2I, I22 and I23 (corresponding to the lintel channels III, H2 and H3) and an integral flange of waste strip I 24 provided with parallel breakoff grooves I25.

It should be noted that the waste strip I24 of the jambs I2 and I3 occupies the same relative position with respect to its 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 sash-receiving channels in alignment, the waste strips I24 and H4 will form a continuous grooved fin around the top and sides of the frame I0.

As may be seen in Figure 3, the sill 24 may comprise a length of extruded stock having a substantially box section and comprised of a sill portion 24! which may have a bevelled sealing ridge 2M which, with the ridge 242, defines a screen sash receiving channel 243. The sill portion 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 14 comprises a hollow body or box portion I46 having a slot adapted to receive a rubber sealing strip I 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 I44 provided with break-off grooves I45. The length of the extruded stock from which the sill I4 is cut is milled at the ends to permit the body portion I40 to be received between the jambs I2 and I3 and the waste strip I24 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 2 15 of the sill 24.

Storm window frames constructed and assembled as above described are preferably made up in stock sizes to carry sashes of the approximate width of the sashes of the primary window on which the frame is to be mounted. The proportions of the several waste strips I24 are then such that their total width will exceed the width of the opening between the casing jambs in any primary window casings. The height of a storm window is also selected so that the waste strips H4 and H14 will exceed the height of the opening between the sill and the lintel of the primary window casing. To fit the storm window, all that need be done is to break off the waste strips along the break-off grooves II5, I25 and I45 until the waste strips fit against the blind stops of the casing, the ends of the sill waste strip I44 being trimmed as necessary. The waste strips are then drilled and screwed to the casing.

While we have disclosed a preferred and tested embodiment of our storm window frame, it is understood that other specific embodiments may be fabricated without departing from the scope of our invention as defined in the followin claims.

What is claimed is:

1. The method of installing a stock size storm window frame within a primary window having arbitrary dimensions without distorting and misaligning said stock size storm window frame comprising the steps of providing a stock size storm window frame including jamb frame members and transverse frame members at least one of said jamb frame members and one of said transverse frame members being bordered by integral fiat coplanar flanges grooved on one surface along longitudinal parallel lines and the surfaces of said co-planar fianges on the reverse side from said one surface being substantially planar to define outwardly of the innermost of said lines associated with each frame member, a tearoff flange comprised of a plurality of tear-off strips, discarding the number of said tear-off strips necessary to accommodate the height and width of said storm window frame to the dimensions of said primary window, and thereupon anchoring said fiat coplanar flanges to said primary window. 2. The method of installing a stock size storm window frame within a primary window having arbitrary dimensions without distorting and misaligning said stock size storm window frame comprising the steps of providing a stock size storm window frame including jamb frame members and transverse frame members at least one of said jamb frame members and one of said transverse frame members being bordered by integral fiat co-planar flanges grooved on one surface along longitudinal parallel lines to progressively shallower depths from the outermost to the innermost of said lines associated with each frame member and the surfaces of said co-planar flanges on the reverse side from said one surface being substantially planar to define outwardly of the innermost of said lines associated with each frame member, a tear-off flange comprised of a plurality of tear-off strips, discarding the number of said tear-off strips necessary to accommodate the height and width of said storm window frame to the dimensions of said primary window, and thereupon anchoring said fiat co-planar flanges to said primary window.
