4 Claims. (Cl.

, This invention relates .toa .windowlsasln .and more particularly to an auxiliary or storm windowsash...v The.. advantages of an auxiliary or storm sash .are Awell .knownfand there. are` many; types of conventional sash that. are adapted to be put on and removed as the weather changes, to protect against the cold and storm, and may be replaced byscreensuin. the summertime.

. A further object/.listo provide.; a sash of the type described in which at least one of the sashes may be raisedor lowered at will for ventilation ori-for cleaning purposes... a K y Y Y One of the. principal advantages of my inventionresides inthe mannerinwhich the frame ofthe sash is fabricatedLwhich enables it to be adapted readily to diiierent sizes and shapes upon installation and the manner in which the frame of the. sash` dove-tails into the Ysupporting members toprovidea completeair-sealing, while at the same time to allow free operation in opening afndlosng-...n s. Y

. otherfadvantageresides in the fact that upon .installation my fittings may be caulked to insure. a completesealing.: y .Y V`r`Other objects and advantages of my construction become apparent from the accompanying drawings, in which-fv v y Fig. l isk an elevation of my invention; e

. Referring more particularly to the drawings, my construction is adapted not only forioriginal installatiosin the building of new windows, but also installations in existing windows, and is a window embodying adapted to be fitted intoethev conventional frame 2i! as an auxiliary to the conventional window 2i. I provide channel members-25 having a pair of inwardly extending Vflanges 26 and 2.1,: and an additional ange 28 at right angles thereto. Flanges 26 and 2l Aprovide a channelZQ in which is formed a U-shaped mem-ber 3B which deiines, with the iianges 25 and 2l, grooves 3! and 32 therein. The flange 28 lis provided at spaced intervals with screw holes 33 for installation purposes. y f

`The channel member is adapted for installation in both the upper and lower sash being only necessary to reverse 4it from one position to the other.` Referring to Fig. 2, the channel member 25 is installed with the-.flange 28. against the window stop 35 for the upper. sash,.while in the lower, the flange 2B is installed against the window stop. In this manner the lower sash 35 may be raised inside theuppersash 3l.

It will be appreciated that the channel members 25 must not only be installed on .the sides of the window for the upper and .lower sash, but at the to'p thereof, as shown at 33. At .the bottom of. the window I. further install a member 6.0, due to the factthat in anormal window the lowersash is of greater length than the upper sash, the member 4E) will compensatefor the difference in length andmake it possible to use an upper and lower-sash of identical size. The member lidisfastened to the inner sill. and window stops by lmeans of screws, lll. At its lower endit is provided with a channel i3 which, after installation, is caulked with a suitable compound. .At its upper edge the, member 40 is provided withfa U-shaped member 45 slightly narrower in width thanthe member itself..

The. window frame is made of prefabricated stock 50 which is provided. at its inner side with aslot. 5l adapted to4 receive a pane of glass 52.

i The slot 5i leads to a chamber 53 in which may be mounted a sealing gasket 54. The member 59 is provided with two flanges 5t and '5l dening the channel. It will be seen that when the' window is fitted theilanges 56 and 51 engage the channels 3l and 3 2 of the-channel member 35, while the U-shaped member 3B is engaged in the channel 58 to insure a close fit.

In making the sash frame 60, the stock 50 is ont to the appropriate length and the holes 6I bored at the desired place. The four sides of the window are then assembled by meansV of the corner piece-52 which h-as inner and

outer portions

53 and 64 matching the sides 65 of the member 5B'. The corner portionv62 is provided with an elbow member 66 which has a channel 61 and the elbow portion is .adapted to fit within chamber '53 behind slot 5I in the memberll;` as indicated in Fig. 6. The elbow member 6571s also provided with tapped holes 68 -to fasten the corners together, As all four sides of the window are constructed of the same material, it is a simple matter to cut the stock to the desired size and quickly t it together by means of the corner members 62.

In the past, most windows of this type have been welded or otherwise permanently fastened together, and when a pane of glass is broken, it is necessary to return them to the factory. With my improved construction, the glass may be readily replaced by removing one end and its adjoining corner portions.

In installing my window the channel strips 25 are fastened to the frame of the window against the stop 33, the channel strips for the upper window having the'flange 28 against the window stops, while the channel strips for the lower window are reversed. Caulking compound is inserted in the channel 30 to completely seal the channel strips to the frame. The member 40 is then put in place. rIhe lower window 3E is put into place first and .the upper window 3l may then be slid into place. In order to hold the upper window in closed position, a hinged latch 15, having an extending member 16 abutting the under side of the window, may be provided on either side. In order to seal the windows when closed, the strip 'll is fastened to the top of the lower window, and a similar strip '|8 is fastened to the bottom of the upper window, as most clearly shown in Fig. 9. Since it may be desired toopen the lower window for ventilation, latches 80 may be provided at convenient places. The latch 80 consists of two members 8| and 82, the latter being a handle member and is pivoted by the screw 83.

As the window is raised, the member 8| will tend to fall outwardly and the window will be caught by the latch surface 84. It will be appreciated that it may be readily released by moving the handle member 82 toward the glass.

When it is desired to remove the windows they are removed in the same way by opening the hinged member and allowing the upper sash to slide downwardly and then by removing the lower sash. Screens 90, as shown in Fig. 13, are provided, having ends 9| adapted to fit within the channel 29. Since an air seal is unnecessary with screens, the end 9| may be rectangular. Obviously, any type of screen may be used, but one most suitable is shown in Figs. 13 and 14, which may be cut of standard stock and provided with a channel 92 and a wedge member 93 to hold the screen in place. The stock may be joined ,by the corner member 94 to hold the screen together.

While the material used does not formv an essential feature of my invention, quite obviously metal or other materials may be molded or pressed as most suitable, since the channel strips may be pressed out of sheetl material, while the stock 50 can most readily be pressed and welded together. Lighter metals may readily be used since there are no stresses or strains involved. The lower sash 3B may also be provided with a handle member 39 to facilitate its raising and lowering. v

I claim:

1. A window sash formed of channel. stock members which meet at the corners of said sash leaving a corner space therebetween, corner members which join said channel members and occupy said corner space, and means for fastening said corner members to said channel members, said channel members being substantially H- shaped in cross section, and having inwardly extending ilanges formed on the inner edges of their sidewalls, thereby dening an inner chamber underneath said flanges, a glass receiving slot between said anges, and an outer guiding channel, said corner members comprising L-shaped elements which are U-shaped in cross section and having side plates aixed thereto and extending in part beyond said L-shaped elements, said L-shaped elements being adapted to enter the inner chambers of adjoining channel members and to complement said glass receiving slot, said side plates being adapted to complement the side walls of said adjoining channel members and to occupy the corner space therebetween, the Y channels formed between the outwardly extending parts of said plates and said L-shaped elements continuing and complementing the outer guiding channels of said channel members.

2. A window sash formed 0f channel members joined at the corners by means of L-shaped members and joined intermediate the corners by means of T-shaped members, and means for fastening said channel members to said L and T-shaped members, said channel members being substantially H-shaped in cross section and having inwardly extending flanges formed on the inner side walls, thereby dening an outer guide channel between the outer side walls, an inner glass receiving slot between the nanges of the inner side walls and a pair of gasket receiving channels underneath said inner wall anges, said L-shaped members being U-shaped in cross section and being provided with side plates which project outwardly to form outer guide channels corresponding to the first mentioned guide channel, said L-shaped members being adapted to enter the space defined by the inner side Walls of the channel members and the flanges thereon and to complement the glass receiving slot between said ilanges, the side plates being positioned to complement the side walls of adjoining channel members and to occupy the corner space therebetween, said T-shaped members being U- shaped in cross section and being provided with outwardly projecting side plates corresponding to the nrst mentioned sideplates and forming outer guide channels corresponding to the first and second mentioned guide channels, said T-shaped members being adapted to enter the space dened by the inner side walls of the channel members and the anges thereon, and to complement the glass receiving slot between said anges, the side plates of said T-shaped members being positioned to complement the side walls of adjoining channel members and to occupy space therebetween.

3. A corner member for use in window sashes, said member comprising an L-shaped element which is U-shaped in cross section, having outwardly projecting side plates dening a guide channel therebetween.

4. A joining member for joining the side rails of window sashes at an angle of said joining member comprising a T-shaped element which is U-shaped in cross section, having outwardly projecting side plates defining a guide channel therebetween.
