6 Claims.

This invention relates to storm windows designed to create a dead air space between a storm iwindow and an outside window of any suitable It is an object of the invention to provide a storm window which may be conveniently installed inside of the usual window, which may be kept in place throughout the year without removal if desired, and which may be opened for ventilation.

It is a further object of the invention so to design an inner storm window that either or both of its sashes can be swung inwardly in such a manner as to permit cleaning of the inner adjacent faces of the storm window and the outside window which are usually inaccessible. This type of construction makes it possible to clean the outer and the inner windows in business or apartment houses without exposing the cleaner to the danger inherent in cleaning windows where the storm window is hung outside.

It is a still further object of the invention to eliminate the necessity of installing and removing storm windows at the end of a winter season and the consequent storing of them on higher floors or in the basement, thus minimizing the danger of breakage.

Furthermore. it is an object of the invention to provide an inner storm window having an airtight t with its frame, thereby creating a dead air space between the outside and the inner window so as to minimize heat transfer from the outside to the inside, or vice versa. This makes a construction particularly desirable for use in air conditioned buildings.

A further important object of the invention is to make it possible to place the lower sash of the storm window in vertical alignment with the upper sash during periods of use. This makes the window present a finished appearance and also insures tightness.

Other objects of the invention will appear from the following description:

Fig. 1l is a detail sectional elevation of a removable strip of a jamb taken on the line I I-I l of Fig. 6; and .v

Fig. l2 is a perspective vie'w showing the corner construction of one of the storm sashes.

The general construction and relation of the parts of the inner storm window is best illustrated in Figs. 2, 3, and 4 of the drawings, in which I0 represents the upper of the pair of sashes of the storm window, and li the lower of the pair of sashes of the storm window. l2 and I3 are the upper and lowerv sashes, respectively, of the 'usual outside double hung window of a building. These sashes of the outer window may have anyusual construction, such as metal sash rails of the general construction shown in Fig. 2. The precise construction ofthe outer window is not a part of this invention `but for purposes of illustration a construction is shown which forms the subject matter of an' application for patent led by me December 28, 1945, Serial No. 637,635, now abandoned.

It may be desirable, in some instances, to have an integral sill I4 for the inner and outer windows. However, in the illustrated form of the invention, the frame of the inner window is constructed of separate pieces of extruded metal, such as the header shown at I5 in Figs. 2 and 3 in which the header of the frame of the inner window is a separate piece, not integrally joined to the frame of the outer window.

For the purpose of illustration only, there is shown at i6 an inner screen which may be rolled up at the top of the window within the room, but adjacent the storm window. This screen, however, is not a feature of the invention and ,is shown merely to illustrate the relative positions of the various parts of the double-hung storm window. l

The sill of the .inner storm window has the configurations shown from the point indicated by the position of the numeral I4 to that indicated by the position of the numeral Il of Fig. 2; and is a separate strip of extruded metal not integrally joined to the sill of the outer window. As shown in this section of the frame, the sill is provided with a shoulder at I8 and an upstanding flange at l'l which form the lower channels for the storm window sashes. The header l5 has a channel wide enough to accommodate the two sashes of the inner window with a parting strip between the two. This parting strip extends onlyabout half of the vertical distance between the header and the sill of the frame, as will be noted in Figs. 3 and 4 where the parting strip terminates at the point indicated by 22. Since the parting strip does not extend below this point 22, there is a common undivided channel at least double the width of either sash in the lower part of the jamb for purposes which will be explained.

The configurations of the jambs of the window frame of both the inner and outer usual windows may be like those shown in Fig. 6 at 24 and 25. The jamb shown in cross-section at 24 is an integral piece of extruded metal which provides sash channels and parting strips for both the inner and outer windows. The frame shown at 26 at the left hand of Fig, 6 consists of two parts with a separate jamb for the inner storm window shown at 28 in Fig. 6. The innermost flange of the jambs of the lower portion of the storm window is removable as is indicated by the construction shown at 30 of Figs. 6 and 11. These Ifliange portions constitute removable sash retaining strips, which complete the inner channels of the jambs of the storm window. They are held in position normally by the device shown in Fig. 10, comprising a handle 32 with a portion thereof constricted as at 34, which restricted portion closely fits the slit of a slotted hole 3G. The flange is so dimensioned that an outward pull of the handle 32 brings the constricted portion of the handle within hole 3S whereupon the strip can be swung outwardly and away from its normal position to that shown at 38 in Fig. 11; and further movement of the flange permits its cornplete removal from the. window. The lower end of the ange is provided with slot 31 which disengages the pin 31 in the frame. When this iiange is thus completely removed, both from the right and left hand sides of the lower jamb of the inner storm window, it then becomes possible to swing inwardly either sash of the window into a position illustrated at 40 or 42 in Fig. 4.

The frame of the inner storm window including the jamb members, the sill and the header 4 are held in position in the walls of the building by strips of resilient plastic material of the general coniiguration indicated at 44 in Figs. 2, 3, 4, and 6. These strips of resilient material are attached to the said frame by slipping two ribs of the strip over ribs 46 of the frame. The body portion of the resilient strips is generally tubular in design; and it can therefore collapse somewhat, as indicated in all sections showing the strips 44 so that the frame of the inner window can be forced into position and held rmly in engagement thereby with the adjacent walls of the building. This feature makes it possible to add an inner storm window to a normal double hung window at any time subsequent to its original construction.

At each side of the header of the frame of the 'storm window, there is provided a suspension for the two sashes consisting of a plurality of roller bearings, illustrated here by three rollers, disposed between the header of the frame and the adjacent walls of the ybuilding at a point illustrated at 48 in Figs'. 2, 3, v4, and 7. The construction of this `rollerbearing is best illustrated by Fig. 9, which shows, `in cross-section, a channel 50 vmade from a piece of sheet metal having two legs bent at a right angle to the web -connecting them, and indentations 52 stamped therein which provide pivot supports for short pieces of tubing 54 suitably dimensioned to Yrevolve on the indentations 52 as bearings when a cable or other sash suspension cord I5' moves over the rollers 54.

The relation of the sash suspension cord Ylli 'to the roller bearings is illustrated clearly in Fig. 9 and also in Figs. 3 and 4 which show the Ycord or cable passing over the rollers aforesaid; cord I6 may be attached by loops or other means tothe sides of the upper rails of the sashes as illustrated at 56 in Figs. 3 and 5.4 From Figs. 2, 3, and 4, it will be notedthat the rollers 54 are disposed along an arc which extends in such a manner that the peripheries of the two outer rollers are in alignment with the center lines ofthe inner and outer sashes of the storm window, so that the said sashes hang vertically downward from the cable I6' attached to said sashes and passing over the rollers. This construction reduces the vertical space which would ordinarily vbe required for a circular pulley of proper diameter, such as is usually employed.

The attachment of the cable'suspension of the sashes to the rails thereof maybe provided by a tubular member 60 shown in detail inFigs. 5 and 8. This member may be attached -to the upper rail of a sash by means shown in Figs. 1, 5, 7 and `8 including a downwardly-projecting flange 62 welded or screwed as at in Figs. 1 Aand 5, to the sash rail. It housesa plunger 66 having an end 68 of reduced diameter. A rubber or other pliable washer 69 may be installed-on the end 68 to cushion its engagement with jambs 24 and 26. Plunger 68 is spring-pressed asby aspring lil and is normally urged outwardly :so vthat 68 will enter holes 12 or 'I4 in the jamb at approximately its central point, i. e., in the position shown in-Figs. 4 and 5. Inv this position, the reduced end 68, when lodged'in hole-12, provides a pivot upon which the upper sash'I- can-swing inwardly into the positions shownfat-4il or v42 in Fig. 4, but only after'the retainingstrips 30 v`of the lower halves of the jambs (see-Figs.-6 yand'll) have been removed from the jambs by pulling the handle 32 out to a position which, 'as previously described, permits removal vof the Ystrips 30-from--the jambs. The lowerfsashfon' the other hand, is similarly pivoted in the hole 'I4 which, it will be noted in Fig. 4, is adjacent to the hole 'IZ but slightly above its horizontal level and located in the sash channel of the lower sash.

The parting rail 20, as previously stated, does not extend below the point 22 where the common sash channel in the lower portion in the jamb is more than twice the width of either sash. I-Iaving such a width, the channel permits movement of sash II from the right hand side of the common sash channel to a parallel position at the left hand side of that channel, thereby placing sash I I in vertical alignment with the upper sash I0, i. e., with the upper outside window as illustrated vin Fig. 2. In accomplishing this, the lower end of the lower sash I I is first inserted behind the shoulder I8 of the sill and then the upper end of the sash is swung inwardly into the position shown in Fig. 2. Having arrived in this position, it will be automatically locked by entrance of the reduced end 68 of plunger 66 into the hole I2, urged by the spring 10.

When it is desired to remove the lower sash I I from this aligned position, a handle 'I6 attached to plunger 60 through oblique slot 'I8 is pressed downwardly, thus compressing spring 'I0 and withdrawing the constricted portion 68 from the hole l2. When this has been effected, the upper portion of the lower sash can then be swung inwardly; and after being raised a short distance can then be pulled from behind the shoulder I8 and then can be moved upwardly into its own proper channel, so as to assume the position shown in Fig. 4, with its resilient weather strip contacting with the header of the frame. The upper end of the lower sash can also be released from its vertical alignment with its upper sash shown in Fig. 2, by withdrawing the reduced end 68 from hole I2 and by moving the upper end of the lower sash upward, thus permitting the end 68 to enter into hole 14. Since upper sash I8 is shorter than lower sash II, it can be pivoted in hole 'I2 and can then be swung inwardly to the positions 40 and 42 shown in that gure. It will be understood that sash I I can be pivoted in hole IB and that with either sash thus swung inwardly, access is provided .to the inner window pane surface of the storm sash and of the outer window sash for cleaning purposes. Plunger 6U of the upper sash I does not have a handle such as 'I6 attached thereto, because it would interfere with vertical movement of both sashes. Accordingly, withdrawal of such plunger 6B from hole 'I2 must be eiected by sidewise manual pressure exerted upon screw head 'II (Fig. 5) after its shank has been unscrewed sufciently to release screwhead TI from any tightened and clamped position.

Both horizontal rails of the lower storm sash and the upper rail of the upper sash may be formed of extruded metal and have a configuration in cross section roughly resembling the figure H shown at 'I9 in Figs. 3 and 4. The lower` rail of the upper sash has the conguration shown at 80 in Figs. 3 and 4, which latter resembles a channel beam, namely, two parallel straight upstanding ilanges connecting by a straight web. The inner surfaces of these ilanges may be provided wth ribs 82 designed to enter channels 84 in the plastic glazing strip 86.

The essential difference between the configurations 'I8 and 80 of the horizontal rails is that rails 'I9 are provided with outstanding hooked ilanges 86 which enter into corresponding channels in extruded pliable strips, such as that shown 6. Vat 88 in Figs. 2 and 3idisposed along the outer edges of the horizontal sash rails. This weather strip section 88 being hollow, as shown, is deformed fairlyeasily (see, for example, 88 in Fig. l) so that it can accommodate itself to inequalities in the sill when it is in the position shown in Fig. 2 and can likewise bend suciently to permit of its sliding over the shoulder I8 when removal of the lower sash from vertical position becomes necessary.

The Stiles of the window sash, on the other hand, are constructed primarily of extruded pliable plastic strips which have the configuration shown at 9D in Fig. 6. Embedded in the bases of these pliable stiles 98 are metal strips 92 which, as will be noted upon reference to Figs. 5 and 12 extend from the lower to the upper sash rails to which each stile strip may be secured by a screw 94 entering a right-angled ange 96 with which the metal stile strips are provided at each end. By this means, the sash frame is assembled after the glass pane has been inserted in its appropriate channel 88 in all of the four glazing strips which encompass the window pane when it is in position.
