6 Claims. 1

This invention relates in general to a self-storing combination storm and screen sash unit and more particularly to improved means for sup porting the sash thereof with respect to each other and substantially within a zone peripheral ly defined by the opposing surfaces of the blind stop and the sill of a conventional, double hung window frame.

Although there are many types of conventional window frames for double hung windows, such as those usually found in industrial or apartment type buildings, features of construction common to most such frames include a sill and a blind stop which latteris generally comprised of a pair of vertical elements and a top, horizontal element. However, the cross-sectional contours of said sill and the blind stop may, and often do, vary substantially from one window frame to another. For example, the exterior side of the blind-stop, which faces towards the outside of the building, sometimes has an ornate bead which prevents securement of storm sash thereto. Often, the exterior surface of the sill is flush with the exterior surface of the blind stop, thereby eliminating the means upon which conventional types of storm sashes are normally supported. If either or both of these conditions exist, it is diflicult at best to mount presently known types of combination storm and screen sashes upon the window frame.

The majority of presently known, combination storm and screen sash units can be conveniently installed only from the outside of the building, even though the sashes thereof may be operated from the inside after installation. Thus, where the window openings are at a considerable height from the ground, such as in oiiiee buildings or apartment houses, the installation of said present units becomes dangerous and/or difficult. Under such circumstances a combination storm and screen sash, unit which is normally installed from within the building would be of great value.

It is further often desirable, particularly in office building, factory and apartment window construction, that the window unit be of the socalled self-storing type. be provided by which at least a portion of the glass panel may be quickly and easily moved out of the way, leaving only a screen panel to close the portion of the window opening formerly closed by said glass panel, in order that it will not be necessary to remove said glass panel from the window assembly for storage purposes.

It will be evident, of course, that although these remarks have been directed particularly toward office, industrial and apartment type buildings, the problems mentioned are by no means limited thereto, but apply also, though perhaps in lesser degree, to individual dwelling units.

Accordingly, a primary object of this inven- That is, means should entirely upon and substantially between the on posed surfaces of the sill and blind stop elements of a double hung window. The upper and lower tion is the provision of a self-storing combination storm and screen sash unit easily mountable upon any window frame wherein at least a portion of the sill thereof lies within a zone defined by the opposing surfaces of the vertical and horizontal elements of the'blind stop.

A further object of this invention is the provision of a combination unit, as aforesaid, mountable entirely upon and substantially between the opposing surfaces of the sill and blind stop of a double hung window frame.

A further object of this invention is the provision of means for supporting the sash of said combination unit with respect to each other and the blind stop and sill of a double hung window frame, whereby the objectionable openings often occurring between said blind stop elements and said sash supporting means are positively eliminated. I

Another object of this invention is the provision of sash supporting means, as aforesaid, mountable upon the opposing surfaces of the sill and blind stop of a double hung window frame by workmen operating from within the building containing said window frame.

A further object of this invention is the provision of a combination unit, as aforesaid, having double hung storm sashes disposed between the opposing surfaces of the sill and blind stop of a double hung window frame whereby a lower storm sash may be stored parallel with an upper storm sash between said upper storm sash and the upper sash of the main window.

A further object of this invention is the provision of a combination unit, as aforesaid, comprised of a lower screen sash, an upper glass sash supported upon said lower screen sash, and a lower glass sash disconnectably supportable in storage position upon said screen sash adjacent to the upperglass sash, all of said sashes being easily and quickly removable from the means sup: porting said sashes between and upon the opposing surfaces of the sill and blind stop of the double hung window frame.

Other objects andpurposes of this invention will become apparent to persons familiar with this type of equipment upon referring to the accompanying drawings and upon reading the following specification.

In meeting those objects and purposes, heretofore mentioned, as well as others incidental thereto and associated therewith, I have provided sash supporting means including guide angles for removably supporting an upper glass sash, a lower glass sash and a lower screen sash glass sashesand the screen sash are slidably and of my invention, reference is made to the accompanying drawings in which:

Construction in general For the purposes of convenience in description, the terms left or leftwardly and right" or rightwardly. as used in this specification, shall be understood to mean leftwardly and right weirdly of, the combination unit, or parts thereof. when positioned as appearing in Figures 1 and 2. or as viewed from'the exterior of. the

building in which the unit is installed. The terms interior or "interiorly and exterior or exterior-1y shall have reference to parts of saidcombination unit toward and away from,

respectively, the interior of the building in which the said combination 'unit Ill is installed. The terms upper" or upwardly and lower or downwardly shall be understood to refer to V the said combination unit and parts thereof when window frame rather than on the exterior surfaces of such a frame as is common with presently Cir known storm window units. A pair of double hung sash structures, carrying glass panels, are mounted within the frame and a sash structure carrying a screen panel may also be mounted in said frame directly below the upper of the two glass carrying sashes. frame structure on the opposing faces of the blind stop permits such mounting to be done from the inside of the building, and yet the structure hereinafter described is of suificient compactness that it will not decrease the total effective size of the window opening by an unreasonable amount The general arrangement can best be seen in Figures 1 to 4, inclusive, wherein the storm and screen sash unit It to which this invention relates is shown as comprised of an upper glass sash II, a lower glass sash i2 and a screen sash I 3 which sashes are all supported within the window frame M of the building.

In the following description, reference will usually be made only to the left side of the window as viewed from the outside with the understanding throughout that the other side is iden tical therewith. In this manner the description will be shortened and simplified without loss of clarity or completeness.

The unit structure generally is comprised of a pair of vertical guide angles i5 and It afiixed to the opposed faces of the blind stop and a similar guide angle ii is affixed to the under.

surface of the blind stop at the top of the Win dow. A sill structure is provided at the bottom 'of the window opening to provide complete mounting of the sash panels. A U-shaped channel is ailixed by its web to the lower endof the vertical guide angle on each side of the window frame to receive and guide the lower glass sash.

It is spaced from the outer flange provided on the vertical guide angles a distance'sufficient to provide therebetween another channel for the reception and guiding of the screen sash. A similar U-shaped channel is afiixed to the top guide angle at the outer portion thereof for reception of the upper end of the upper glass sash and suitable springs are afiixed to the respective vertical guide angles near the upper ends thereof for holding the upper glass sash against the outer flange of said guide angles.

Ifhe window. frame [4 (Figures 1 to 5) with which the herein disclosed storm and screen sash unit may be used is indicated generally as comprised of a window sill 22 and a blind stop 23. having a top horizontal element 24, a left ver-- tical element 25 and a right vertical element 26.

The unit frame structure The right, left and topguide angles 15, It, 11, s

respectively, (Figures 1, 2, 5 and 7) have substantially similar cross-sectional contours, and are. provided with side flanges 18, 18a, and 18b and. face, flanges 49, I80. and 191), respectively, which are preferably.perpendicularly disposed with respectto each other. These angles may be. fabricated in any convenient, conventional manner, such as by rolling or extruding, from any suitable material, such as aluminum or steel. Referring now only to the left guide angle 16,

and understanding that the others are duplicates thereof, the side flange file is provided with a V longitudinally disposed bead 21a (Figures 1., 2 and 7). which bead extends out of the plane of theside flange in the. opposite direction to that Such bead is preferably The mounting of the spaced therefrom a distance slightly less than the thickness of one of said sashes.

The left guide angle I6 is secured to the inner face 21 (Figure 7) of the left blind stop element 25 by any suitable means, such as the nails 28 (Figure 3) so that the bead 2Ia, thereof, is po sitioned adjacent to the exterior edge 29 of the element 25, and further so that the face flange I9a extends toward the right blind stop element The side flange I8 of the right guide angle I5 is similarly secured to the inner face 3I of the right element 26.

A guide channel 48 (Figures 4 and 7), of U- shaped cross-section, which is approximately half as long as the vertical guide angle I6 is secured to the inner surface of the side flange I8a near the lower end thereof, said securement being by any convenient means, such as the nails 5i which also hold the lower part of the guide angle I6 against the blind stop element 25. Its exterior flange 52 (Figure 3), which extendsupwardly substantially further than the interior flange 53 is parallel with and spaced from the interior surface of the adjacent face flange Illa a distance sufllciently greater than the thickness of the screen sash to permit reception of said screen sash between said flanges. The flanges of the guide channel are spaced from each other a distance sufliciently greater than the thickness of the lower glass sash II to permit its snug,

sliding reception therebetween.

The top guide angle I'I (Figures 1 and 5. ex-

tends between the upper ends of the blind stop elements and 26, and its side flange I81) is secured to the lower face 33 of the top blind stop element 24 by any suitable means in a manner similar to that of said side angles. The opposite ends of the face flange I9b overlap the exterior surfaces of the face flanges I9 and I911, and the exterior portions of the opposite ends of the side flange I8b extend beyond the upper ends of the side flanges I8 and Illa.

The holding channel 68 (Figure 5) extends between the upper opposed edges of the face flanges I9 and I9a, and is secured to the lower surface of the side flange I8b by any suitable means such as the screws or rivets 'II The exterior, depending flange I2 of said holding channel preferably extends downwardly approximately the same distance as the adjacent face flange I91) and is disposed snugly adjacent thereto.

A removable sash support base 35 (Figures 1 and 4), having a riser flange 36 and a support flange 31, substantially perpendicularv thereto, extends between the lower ends of the guide angles I5 and I6. The support base 35 is preferably disposed so that the opposite ends of the riser flange 36 bear against and are substantially parallel with the interior surfaces of the face flanges I9 and I9a, and further so that the support flange 31, which extends interiorly from the upper edge of the riser flange 36 for support of the lower glass sash I2, lies substantially within a horizontal plane spaced upwardly from the window sill 22 when the lower edge of the riser flange 36 is resting thereupon. An Lshaped sill plate 38 (Figures 3 and 4) is secured upon the sill 2'2, by means such as the nails 42, and extends between the lower ends of the side flanges I8 and I8a so that its vertical flange 33 extends downwardly from its horizontal flange ll, The vertical flange 39, which is parallel with the plane of said face flanges I9 and I9a, is spaced interiorly therefrom sufficiently to permit snug reception of the riser flange 38 between said face flanges and the vertical flange 39.

An L-shaped support angle 43 (Figures 1 and 4), whose length is preferably slightly less than the distance between the opposing edges of the face flanges I 9 and Illa, is secured to the external surface of the riser flange 36 of the support base 35. The support angle 43 is preferably parallel with, and spaced downwardly from, the support flange 31 and extends in the opposite direction therefrom for supporting the screen sash I3.

The glass and, screefn sash structure v of this invention. However, the combined vertical length of the upper glass sash II and the screen sash I3 is preferably slightly less than the vertical distance between the support flange 31 of the base 35 and the web 69 of the holding channel 58 to permit insertion of these sashes.

The screen sash I3 (Figures 1, 3, 4 and 7) may be comprised of any convenient, conventional type of screening mounted in a metallic frame of a conventional type. Said frame is preferably substantially equal in thickness to the frame of the said glass sashes, for reasons which will hereinafter become apparent. The screen sash (Figure 7), which is preferably identical in width to the glass sash, may, for example, be comprised of frame elements or rails 44, each of which have a tubular portion and a portion providing a sidewardly opening, longitudinally disposed slot 45, into which an edge of the screen panel 46 may be placed and held fast by means of a suitable strip 41.

The vertical side rail 58 of the upper glass sash II (Figures 1 and 2) is held against the interior surfaces of the face flange I9a by the flat spring BI which spring is secured to the inner surface 21 of the vertical blindstop element 25, It will be clearly understood that the number and type of springs used may be varied within the scope of this invention depending upon the specific requirements and the size of the sash. The top rail 61 is snugly and slidably received into the holding channel 58.

As shown in Figure 4, the lower rail 53 of the upper glass sash I I is supported upon the upper rail 64 of the screen sash I3. A plurality of positioning ears 65 (Figure 4) are secured to the upper edge of the screen rail 64 for reception into a slot 56 in the lower edge of the lower rail 63 of the upper glass sash II, thereby preventing accidental, lateral displacement of the lower rail 63 of the upper glass sash with respect to the screen upper rail 64 when said upper glass sash and screen sash are properly assembled.

In normal operation, the lower glass sash I2 is disposed between the flanges of the guide channels 48 and 49, the lower rail I3 thereof rests upon the support flange 31 of the sash support base 35. The fiat springs SI and 62 are preferably so tensioned and so positioned with respect to the face flanges I9 and I9a,'that the lower glass sash 12 may be moved upwardly and downwardly beate, 951

of. the frame of the, upper. glass sash H.

The upper rail, 64' of the screen sash i3 is.

. wardly within its supporting channel members 48 the support bracket 83 will not scratch the glass. However; the supportbracket 83 does extend a sum'cient. distance from the screen upper mu B l to engage and support the lower rail 53 of the lower glass sash l2 when said lower glass sash is lifted above said bracket and then moved downwardly thereagainst. Support bracket be is correspondingly positioned near the other side of the screen sash and functions similarly.

In raised position the said lower sash will be underthe springs 81 and 62 and the action thereof will urge'it. snugly against the upper screen rail so-thatthere is no reasonable likelihood that the said lower sash will become accidentally disengaged from. its supporting brackets.

Cut-out portions 93 may be provided to receive the said brackets and to provide a fiat surface for them to'bear against. 4 1 v When the lower, glass sash is thus resting upon the brackets 83. and 84,. it is in the storage position. adjacent to and. substantially parallel with V the upper glass sash ll.

Since the lower glass sash and screen sash are a of substantially the same length, the sill support fangle 43 is spaced downwardly from the adiacent support. flange 31 and the support brackets 83 and 84 "are disposed near the lower edge of the screen sash upper rail 64 to prevent interference between the said support. brackets and the upper rail 88 of the lower glass sash l2 when said lower sash. is; resting upon the support flange 3?. Although the length of the lower glass sash may be varied somewhat, it will be recognized that said length must be such. that said lower glass sash can be received between the support brackets and the top guide angle it.

The above described vertical ofiset between the screen and lower glass sash provides an overlap between the lower rail of the upper sash and the upper rail ofthe lower glass sash, as shown in Figure l, which inhibits the passage. of. air

' between the; said two rails. To provide further; L against such passage of air, a resilient, preferably metallic sealing member 89 is secured to the upper rail 88 of the lower sash l2 (Figures 3. and and extends between the opposed edges of the flanges on the channel, members 48 and 49. I 7 h A rectangularly shaped handle M (Figures 3, 4, 6, 8 and 9), preferably fabricated from wire, is slideably engaged, alongv its upper portion 76 by a cylindrical bracket '13 which bracket is secured tothe lower rail 13 of the lower glass sash E2 in any conventional manner near the leftward end thereof. The handle 14 is horizontally slideable toward and away from the vertical guide angle I6. A plurality, here two, of integral protrusions BI and 82 are provided along the interior faces of the interior flange 53 of the channel member t8.v These extend into the path of the vertical movement of the handle when it is extended toward the adjacent guide 'angle l8 and engages said upper portion 16 to DOSES.

. 3 provide support for the lower glass sash H in a partially raised position for ventilation pursimilar handle construction 19' is provided at the rightward side of..the lower sash together with similar supporting and cooperating structure.

Alternate structures In the event that the sill 9| (Figure 11) has an exterior edge 92 flush with the exterior edge of the blind stop 93, the lower end of the'vertical face flange 95 may be bent inwardly to engage the window sill exterior edge 92 thereby improving the exterior appearance of the combination unit II]. All other features of the structure hereinabove described in detail remain the same. a

If the blind stop- (Figure 10) should have an ornamental head 9'! along the exterior'edge thereof, there will be no interference with the mounting of the unit 'herein described and it may be applied in exactly the same manner as above described. This is not true with other unitswith which I am-familar.

The combination unit l0 may be converted into solely a storm window unit by removin thescreen sash l3 therefrom and placing a pair of channel members (not shown), between the face flanges i9 and Mia and the exterior flanges of theU- channels in place of the screen for the'purpose of supporting the upper: glass sash H.

In Figure 12 there appears a modification which adds materially to the appearance of the unit. A strip lilo is bent. at its upper edge and is inserted into, and held by, the lower rail .of the upper sash in. the same manner as the glass panel. The lower edge extends downwardly s'uiliciently to cover the. meeting line of the lower edge vof the upper sash, and the upper edge of the The storm window and screen sash frame is first mounted on the sill and opposed faces of the blind stop of the main window frame with which the storm. window and, screen unitis to be used. The panels may then be installed. First,

I the lower edge of the screen panel is inserted between the U-channels, and the face flanges I 9 and I9a of the guide angles and is passed downwardly until it rests on the screen. support angle 43. The upper glass sash is then inserted under the. springs 6| and 62 andfmoved upwardly until it is received into the holding channel 68.

The lower edge of the upper glass sash is then moved first 'exteriorly toward the face flanges l9 and Illa and then downwardly against the screen sash so that the positioning cars thereon served that the interior flanges of the two respec- -tive U-channels are cut off somewhat shorter than are the webs and outer flanges thereofin order to facilitate this insertion.

When it becomes desirable to provide a limited amount of ventilation through the unit Hi, the

upwardly to its full open position, which is the same as its storage position, the said lower sash is, with the handles 74 and first moved toward each other to clear said protrusions 8i and 82, lifted upwardly until the lower rail 13 thereof is entirely above the brackets 33 and 86. At this point, said lower sash will have been urged between the springs 6i and (i2 and the face flanges [9a and IS. The tension of the springs GI and 52 will urge the lower sash exteriorly against the upper glass sash. A slight downward movement of the lower glass sash will the cause the surfaces defined by the cut out portions 99 to rest upon the upper surfaces of the brackets 83 and 84. The brackets will support saidlower glass sash in its upper or storage position and the action of said springs 6| and 62 will assure that said sash will not accidentally slip off said supporting brackets.

It will be seen that the support brackets 83 and 84 provide an uncomplicated, positive means for supporting the lower glass sash I2 in the storage position without necessitating that said lower sash be moved inwardly of a plane defined by the interior edges of the blind stop 23 at any time, including the movement of said lower glass sash upwardly into. or downwardly out of said storage position.

The lower glass sash is removed from the combination unit by sliding it downwardly and interiorly from the storage position after disengaging the lower rail '13 thereof from the brackets 83 and 84. The upper glass sash Il may then be removed by urging it upwardly slightly until it is disengaged from the positioning ears 65 and then drawing it interiorly and downwardly. This need for upward movement of the upper glass sash to effect such disengagement is the reason why the distance between the said web 69 of the channel I38 and the flange 3'! of the base 35 is slightly greater than the combined vertical lengths of the screen sash l3 and upper glass sash H. The screen sash l3 may also be removed by moving it upwardly to clear the U- channels 48 and 49, and then interiorly and downwardly.

Although the above mentioned drawings and description apply to one particular, preferred embodiment of the invention, it is not my intention, implied or otherwise, to eliminate other variations or modifications which do not depart from the scope of the invention unless specifically stated to the contrary in the hereinafter appended claims.
