The present invention relates to improvements in. storm windows and therewith interchangeable screens of the type which are mountable.

either on the regular double hung type of sash window or applicable to the outside of the frame thereof with provisions for-removing and interchanging screen panels and storm window glass.

It is one of the objects of the present invention to provide a type of storm window in which the,

glass to constitute the storm window, said glass being readily attached and detached from the sash itselfwithout the use of any special tools.

Other objects of the invention include the provision of special sliding members for the attachment and securing of the panels of the sash or the special frames provided therefor.

Fig. 15 is a fragmentary perspective view of the frame which holds either the glass or the screen panel; and a Fig. 16 is a fragmentary perspective view, showing the details of the manner of attaching the permanent holding frame to the outer parts of a window frame.

The present invention provides a simple, inexpensive and easily applied storm window or screen which isneat in appearance and which renders either the glass or the screens readily removable without the use of screws, bolts or parts of any kind. It is applicable both to windows of the common casement type, as well as to double hung windows.

Referring first to that part of the invention which relates to storm windows which are slidable with double hung sash, such as illustrated in Figs. 1 through 9, there is provided in connection with each sash an extra sheet of glass constituting .the storm window which sheet is held within a surrounding frame which encloses the edges of the glass on all four sides thereof. 0n the outsideof the upper sash, and on the inside of the lower sash, there are provided, respectively, rectangular frames which are capable of looking engagement with the frames that hold the extra glass, slidable means being also provided, which, in conjunction with suitable slots and proje'ctions, are capable of effectively afiixing the framed extra glass on the outside of the upper sash and on the inside of the lower sash. As a result there will be obtained many of the benefits of a storm window, the dead air space between the ordinary glass of the window and the added glass serving as an efiective insulating medium against loss of heat.

In Fig. 2 which shows a window as it appears from the outside, the window will be seen consisting of a window frame 11 within which are hung the two double hung sash l8 and IS, the latter being the lower sash and the former the upper. Afllxed to the outer side of the upper sash I8 is the outside storm window while afllxed to the inside of the lower sash I9 is the inner storm window 2|. This is accomplished by surrounding a pane of glass 22 by a metallic channel frame 23. In order to insure a tight weatherproof fit between the channel frame 23 and the pane 22, suitable resilient insulating material, for example, sponge rubber 24, or some mastic composition is interposed between the frame 23 and the pane 22 (see particularly Fig. 6). Permanently affixed to the sash i9 is a channel frame 25 which is preferably nailed, for example by means of nails 26, to the sash l9 (see Fig. 6). In order to insure a weather tight fit a suitable mastic composition, for instance sponge rubber 21, substantially fills the inside of the channel frame 25, and therefore causes a part of this material to abut tightly against the sash 19.

This frame is further illustrated in Fig. 8 which also shows the manner of assembly at the corners, which is as follows: A suitable connecting member 28 (illustrated on an enlarged scale in Fig. 9) and which is provided with a number of cut out portions 29, is forced with each of its legs into the interior of channel frame 25 so as to lie between the outer and inner flanges whereafter the inner flange is deformed so as to extend into the cut out portions or recesses 29, thereby locking the connecting member 28 in place, and therefore also serving to keep the frame members tightly together at the point of juncture.

The I permanent frame 25 is moreover more fully illustrated in Fig. '7 where it will be seen that it has a longitudinal depression 32 which serves to contain the heads of the nails'26. It also has a rolled or bent over edge 33 and two terminal flanges 3i and 34 which lie in the same plane and both of which abut against the sash.

The frame which holds the pane 22, consists of a sheet metal channel a portion of which is illustrated in perspective in Fig. 5 and is broadly designated by the reference numeral 23. This channel frame 23 consists of an outer flange 35 and an inner flange 36, which lie in planes substantially parallel to each other, the ends of the flanges 35 and 35, however, being obliquely bent toward each other at 31 and 38, so as to be in gripping engagement with the pane 22. Depending from the lower flange 36 is a web 33 which terminates in a further horizontally extending web 40 which leads to a further downwardly extending web 4|, the sheet then being bent 180 to form a vertically extending web portion 42 which in turn leads to an obliquely extendin web portion 43 which leads directly to the upp r flange 35, eventuating a channel member of substantially the shape shown in Fig. 5. The rounded bottom portion 44, as can best be seen in Figs. 5 and 6, is cut away to provide a cut out portion 45 and a corresponding slot 45' while the obliquely extending web portion 43 is provided with a slot 46.

The permanent channel 25 as may best be seen in Fig, '7 is cut away to provide a slot 41. A slidable latch 48 serves to connect the frame 23 with the permanently afllxed channel frame 25.

I In connecting the two frames 23 and 25 use is made of a net metal strip 49 (Figs. 3 and 6) which is inserted into position within the member 23 by being slipped through the slot 45.. The upper edge of said strip has an upwardly extendin tongue 50 which passes through and beyond slot 46 when said strip is in place. The latch 48 comprises a slidable member 5| (see Fig. 4) having an upper bead 52 and also a flange 53 at its lower edge, the latter being provided with an extension 54, which last mentioned portion forms the actual latching means. As can best be seen in Fig. 6, the flange 53 is bent rearwardly and then upwardly so as to lie in the slot or cut-out 45 and engage behind the part 4| of the channel member 23, while the extension 54 is disposed at a right angle to said flange so as to enable it to slidingly engage with the portion 33 of the channel member 25 thereby holding the two channel members 23 and 25 together. The extension 54 is of such length as to permit it to pass through the slot 41. The upper head 52 of the member ii is bent around and slidingly engages the extension 50 of member 49. Shoulders 45" at the ends of slot 45 serve to limit the amplitude of sliding movement of latch 48.

In assembling the parts, the frame 23 has attached thereto a soft rubber gasket 55 by means of a. suitable adhesive, this being secured to flange 36 of said channel member. This soft rubber gasket 55 is pressed against the outerflange 30 of the channel member 25, while the tongue 54 of the latch 48 is in such a position that it will register with and pass through the cut away or slot 4'! of the channel member 25, whereafter the latch 48 is slid laterally so as to cause the tongue 54 to engage underneath the portion 33 of channel member 25, thereby locking the parts together.

It will be self evident that a plurality of these latching members 48 will be necessary, and for example, eight of them have been indicated in Fig. 1, although it is obvious that perhaps four of them will suffice, while even a larger number than eight might be used. 4

By reason of the' fact that the soft rubber gasket 55 is tightly pressed against the upper flange 35 of channel member 23, there will be a tight flt between the two channel members, thus excluding dust, water and air. essary to do to aflix the storm window is to press the pane 22 and the surrounding channel member frame 23 against the already affixed channel member 25 with the latch members in such position that they will fit into and pass through the cut away portions ll of the said frame member 25, and then to slide the latch members until they engage as described.

While the method of aiflxing the device has been described in full in connection with the sash IS in Fig. 6, there is also shown in place the regular window glass 51 kept tight by a strip of putty 51. It will be obvious that exactly the same arrangement is used in connection with the upper sash l8 and the window 20 except that in this case the storm window is on the outside. By reason of this construction it is possible to slide the window up and down without in any way interfering with the dead air space between the regular window glass and the extra panes 20 and 2|.

The metallic parts are preferably made of some non-rusting sheet metal such as aluninum or aluminum alloy, or brass, copper, and the like.

Where screening is to be used, it is preferred All that it is nec-.

to use the construction such as illustrated in Figs.

through 16.

In this construction there are applied to the 7 outside sash, frame d8 of the sash (see Fig. 1].),

sheet metal angular housings ti which are pro vided with nail holes 52 for purposes of nailing them to the frame 69. The lower side of the housing member 8i may be provided with drain and ventilating openings 53 and dd respectively. The lower h'ousingmember 6i is nailed to the sill M of the window. These members ti thus form a box like framework or housing within the window frame dd.

Amxed to the inwardly extending flanges bl of the housing members stare the permanent retaining frame members 8-5 which perform substantially tire same function as the channel frames illustrated in connection with Figs. 1 through 9, except that their manner of attaching is different. An end view, partly cut away, of the retaining frame 55 is shrown in Figs. 12 and 14 where it will be seen that it consists of a vertical web portion 68, and therefrom horizontally extending upper flange bl, a parallelly thereto disposed lower flange lit, the flange db having a downwardly extending portion db, a horizontal portion ii! which is than bent outwardly and upwardly at ll and i2, and finally bent rearwardly to form the flange it.

The forward edge of the upper flange 6? has a downwardly extending portion it, horizontally extending portion it, another downwardly extending portion l5 and a horizontally extending terminal portion ll which latter lies directly above and parallel to the flange portion l3 leaving, however, a slight space 78 therebetween. This space is adapted to receive the inwardly extending flange portions iii of the housing inembers El. Self tapping screws it, or other suitable fasteners, are employed to fasten the parts 'Bi, i7 and it together as shown in Fig. 12.

Therefore by this construction the retaining frame 65 will be kept in place and wlll extend all around the window, there being two of these, one for the upper window and one for the lower window, but both bearing the same reference numeral, as they are identical in structure. They are connected together at about the center of the window by a transverse strip till, which performs the same function relative to the flanges Id and ii as do the flanges 6i of the housing frame.

There will thus be present two frames 85 which may either serve to support storm window panes 22 or screens 82. These screens 32 or panes 22 are retained in metallic channel frames Zil which are identical in construction with those already described, when glass is used. However, it a screen is to be used, for instance as indicated in Figs. 10 and 12, a. suitable screen fabric 82 may have at its outer periphery suitable strips 33, the screen extending into a. suitably screen-retaining frame at which consists of a substantially closed channel into which the screenis inserted and crimped as at 85. Such types of frames are well known. The thickness oil-the screen frame did is preferably the same thickness as the window pane 22 so that frame member 23, such as already described, may be employed.

In this form of the invention, the locking of the glass pane or screen holder or frame 23 to the retaining frame it is made possible by forming slots 85 in portions it and iii of said frame 65 through which the tongues 5d of the latch 48 may pass as best seen in Fig. 14. The portion It is slotted at t! to allow the tongues lid to engage under the portion 15, upon sliding of the latch member 38, thereby lockingthe parts toather. l

The frame 23 may, if desired, be fastened together at the corners in substantially the manner shown in Fig. 15 in which the vertical portion of the frame is provided with a slot 88 near the upper end thereof through which an ear 89 extends, being bent upwardly as shown in the figure, and therefore serving to hold together the miter-ed corners of the metallic channel frame 23.

It will be evident that if desired a 'pane 22 may replace the screen $2 or two screens 82 may be used, both in the upper and lower part of the window frame so that the window may be opened from either top or bottom and yet have the benefit oi a screen, or the entire window may be closed with window panes 22 to serve as a storm window.

Inasmuch as both the screen and the pane can be inserted from the inside of the window, there will be no necessity for going outside of the building to place either the screen or the storm window in position; and even the housing frame 6! may be applied from the inside of the building! It will be obvious that the present construction presents'many structural advantages and is also extremely convenient for use by the comparatively unskilled householder, and is particularly advantageous in that it is not necessary to use ladders or scaffolding in order to put these storm windows or screens in place, as all this can be done from within the building. The advantages in case of tall apartment buildings and the like will be immediately apparent.

The exact shape of the various parts may of course be departed from to a considerable extent provided only that the inter-relationship of the parts remains substantially as shown and will accomplish substanitally the same functions.

While metal has been described as the preferred material for manufacturing the channel frames, it will be obvious that suitable plastic material may be used to replace them, and modern industry knows many such materials; which are both weather-proof and have the necessary strength and resilience to operate as shown.

Thus when making the sliding latch member d5, this may be made of a suitable plastic sheet material which may, if desired, be molded into position while hot, and which will retain its shape after cooling down.

While the methods of connecting the mitered ends of the frame are convenient as shown herein, the invention is not by any means to be limited to this manner of connecting the mitered corners of the frame, as many other mechanical methods are known to eifect this purpose.
