Description:

This invention relates to metallic sash storm windows and particularly to the type thereof designed for application to casement windows.

The major purpose of this invention is to provide a storm window for application to a casement window which will have small and neat parts for holding the glass or other panel, and yet fit the casement window tightly, smoothly, and with a trim appearance.

In pursuance of this major purpose, it is a further object of this invention to provide a storm window having metal supports, fastening means, and sashes which are capable of being readily fastened to a casement window.

It is a further object of this invention to provide a storm window which can be applied to and removed from a casement window with a minimum of labor.

A further object of this invention is to provide a storm window for application to a casement window which will open and close with the vent of said casement window easily and readily, and, when in a closed position, will make a tight weather seal against adjacent stationary portions of the window.

A further object of this invention is to provide a storm window for application to a casement window in which there will be required a minimum of light materials for construction but the window will be strong and rigid.

In the art of making storm windows as heretofore known, casement windows could ordinarily be provided with storm sash only by means which were bulky in appearance, clumsy in operation, and difficult of application and removal.

Particularly, prior existing storm sash, when applied to a casement window, often would not permit the opening of any portion of the casement window without either great inconvenience caused by the necessity of special manipulation of the storm sash, failure of the storm sash to seal tightly when again closed, or both.

This invention solves this difficulty by providing a storm sash which is carried solely by the frame of the casement window in which certain portions thereof are independently mounted on the stationary part of said casement window, and other portions are mounted on the movable part of said casement window; and effective means are provided for sealing the meeting surfaces of said members against entry of weather when said window is closed.

Referring to the drawings: Fig. 1 represents an overall view of a conventional casement window as seen from the outside, with my improved storm sash applied thereto.

Fig. 14 is a view similar to Fig. 12 and showing alternative means for holding the sash frame in place. In the description following hereinafter, it will be understood that the term "casement window," or "casement window frame," shall refer to the casement-type window or frame thereof which is installed in a house or other building and to which the storm window is being applied. The term "storm sash main frame" shall refer to the portion of the storm window construction which is designated generally by the numeral 2 and comprises the relatively permanent structure applied to the casement window. The term "storm window sash" refers to the portion of the storm window structure removably mounted on the storm sash main frame and holding the glass.

Referring now to the drawings and particularly to Fig. 1; there is indicated at I the outer frame of a casement window which may be made of any material or of any conventional shape without changing the scope of this-invention, but which for the purpose of the hereinafter-following description is assumed to be made of steel, and is further assumed to be of substantially the cross section shown in FIgures 5 and 6. This casement window has panels supported by members 5, and includes a vent having panels 47, 48, 48, 50, 51, and 52 thereof, which vent is mounted in a hinged frame for opening in the usual manner. The remaining panels are stationary. The hinges for opening said vent are indicated generally at 6 and Sa.

Mounted on frame S is the storm sash main frame 2, the detailed construction of which is shown in Fig. 2. Referring thereto, it will be seen that storm window frame is made from sheet metal which can be readily rolled into shape as shown. Member 23 of storm sash main frame 2 has opening 25 therein for reception of any convenient fastening means (such as screw 41 shown in Fig. 6) by which frame 2 is fixed securely to casement frame I. Member 24 is substantially parallel to member 23 and is spaced therefrom a convenient distance (approximately one-quarter inch In present installations) and serves to support the storm sash as also shown in Fig. 6.

Since, as illustrated in Fig. 9 and explained hereinafter, parts 22 and 28 of this frame member may be cut out to accommodate a hinge, a hinge butt or other projection out from the surface of the casement sash in the region of said frame, it will be evident that part 24 must be spaced from part 23 at least a distance greater than the greatest such projection encountered in a particular installation. This is necessary in order that proper cutout may be provided as shown in Fig. 9 without cutting into the sash supporting ledge 24 and spoiling the barrier provided thereby to leakage of rain, cold air or wind. Member 24 has opening 26 therein to permit a screw driver or other operating tool to reach the fastening member in opening 25. Frame 2 has a flange shown at 21 and a substantially smooth and flat side shown at 22 for purposes to be described hereinafter.

When there is used the form of means for locking the storm window sash onto the storm window frame shown in Fig. 14, frame 2 also has opening 27 therein, but this will be omitted when other locking means are used.

The corner construction of frame 2 is shown in Fig. 3, where a right-angular cut is made through members 23 and 24 and through the inner side of flange 2 by which frame 2 may be bent to form a neat corner.

It will be seen that the above-mentioned rightangular cut is easily made by a fixed die so that construction is rapid and accurate.

Frame 2 is ordinarily made in two separate strips, having corers as above described, and encompassing the sides of a sash section, as at 2a, 2b, 2c, 2d, and 2e. The same is provided for the other sections shown. It is hence usually necessary to fasten abutting ends together in only two places, as 2a and 2d, for each window section.

For the upper section having sash members 14 and 15, one meeting point is shown at 2a and 2b and a detail thereof shown in Fig. 4. A small rectangular plate 18 is inserted within flange 21 of frame member 2 and held in place by embossings IS. The end 2b is then drawn onto plate i0 and embossed thereon similarly to the end 2a.

This makes a strong, continuous frame, easily assembled for installation on the site.

It is evident that although I have found two pieces to be the most satisfactory for most purposes, that this sash frame can be made in one piece or many pieces depending upon the size In of the panel being handled, the manufacturing and transportation facilities available, and installation conditions. In any event, the abutting ends, whether one or many for each panel, are all joined together in the same manner as described above for the joint at 2a and 2b.

For a window of the type shown in Fig. 1, four of these frames are made, one for the section holding sash 14 and 15, one for the section holding sash 3 and 8, one for the movable section holding sash 9 and 10, and one for the section holding sash 1 and 12. These are fastened to the casement window frame I as described and are left in place permanently insofar as the storm window is concerned, even though the sash be removed for reglazing or storage, but can be readily removed whenever desired.

The storm sash is preferably constructed as shown in various places, such as at 9 in Fig. 6.

It is merely sheet metal rolled to the form shown and retaining a window panel between the parallel sides thereof with the assistance of a strip of rubber, fiber, or other convenient binding and shock-absorbing material with corners and abutting ends constructed in any of many conventional ways. This sash may also be constructed as disclosed and claimed in detail in my Patent No. 2,291,726, or any other convenient manner which will provide a sash of only slightly greater thickness than the thickness of the window panel itself. However constructed, these sash panels are made to fit snugly within each of the four main frame sections 2 above described. They are received into said frame sections 2 in the angle between member 24 and flange 21, lying against 43 member 24 and within the recess defined by flange 21 as it extends around each section. They are held in place by hinges on the one side of each of them (as 63 in Fig. 1) and by locking means on the other side of each of them (as 64 in Fig. 1).

5o To elaborate on the mounting of the sash into the frame, reference is made by way of example to the panel containing sash members 3 and 8, as shown in Figures 6, 8, and 10, and it will be understood that all of the other panels are simiC5 larly mounted. Referring first to the hinge construction, it will be seen in Fig. 8 that a section is cut out at 35 from the extremity of flange 21 in frame member 2. The receiving portion of the hinge is a strip of metal having a fiat portion 32 inserted into cut-out 35, embossed into place at 32b, and provided with rolled-over portion 32a for the reception of the hinge pin. Sash frame 10 is provided with a similar member having flat portion 33 which is fastened in any convenient manner, such as by a screw at 33b, to said sash 10 and provided with a rolled-over end at 33a. This grasps and firmly holds a pin 34. Pin 34 is inserted into the opening in rolled-over member 32a when the hinge is in operating position.

Similar hinges in any convenient number are used on each of the sash sections as shown generally in Mg. 1.

It will be seen that these hinges hold one side of each window section in place with respect to the main frame section 2. The opposite side of each of said window sections is held in place by either of the locking means shown in Fig. 12 or in Fig. 14.

Referring first to Fig. 12, it will be seen that sash member 8 lies against flange 24 in the same manner as shown in Figures 5 and 6. It is held in place by a wire clip 29 inserted through an opening 28 made in the flange 21 of frame member 2, and extending through said flange 21 to a point beyond member 24.

It is evident that by having the flat side of the sash firmly pressed against the flat surface of flange 24, a wide surface seal will be obtained around the entire perimeter of each window section so that no leakage therethrough is possible.

Referring now to Fig. 14 for alternative means, an opening is cut in the bottom of the sash frame as shown at 42 and a portion of the resilient panel-containing material is cut out to permit the reception of slide 43 between the panel and the side of the window sash as shown. Slide 43 extends through opening 42 and onward through opening 46, which is placed in the flange 21 of frame 2 in position aligned to receive slide 43.

By placing a series of similar slides in any conveniently selected number around each of the storm window sections, the said sections can be held firmly in place against flange 24 around the entire lengths of frame members 2.

Clip 28 is shaped as shown in Fig. 12 with a shank 57, a bent-over head portion 02, and a bent foot 80. Shank 87 is of sufficient length that when clip 29 is in place with foot 30 resting tightly against the under side of member 24, its head 62 will press tightly against the upper surface of sash 8 to hold the same firmly in place.

In installing clip 29, the opening 28 is made of sufficient width to permit passage of foot 30 when the clip is turned so that foot 30 is parallel to the frame member 2. The clip is then inserted, moved downward to engage foot 30 under member 24; then with any convenient tool, such as a prick-punch, the two depressed portions 58 and 59 are made, one on each side of shank 57, in the side 61 of frame 2 at approximately the midpoint of flange 21. These two depressed portions, together with foot 30 which bears tightly against member 24, hold clip 29 firmly in place. Clip 29 can rotate on its shank 57, but can not move laterally. Obviously, the placing of clip 29 in place and providing said raised portions 58 and 69 can be accomplished easily and speedily. The clip is turned so that head 62 Is in line with flange 21 and the sash' (as sash 8) is then placed in position on member 24 of frame member 2, after which head 62 is turned back over the sash and holds it firmly in position. It is evident that any convenient number of clips may be used and will be applied to all frame members and sash members in the same manner described above.

It will be seen that removal of the window is easy for either form of fastening means shown merely by disengaging the clip 29 or the slide 43 as the case may be, swinging the window outward, and lifting the hinges out of position.

Thus the windows can readily be swung outward for washing, or the entire window can be readily removed or reinstalled as called for by changing seasons.

Attention is called to the fact that although in some installations it may be omitted, best sealing and heat retention is obtained by the use of an insulating strip (which may be any sealing tape or conventional friction tape) at 44 and 45 and all corresponding positions to assure that irregularities of the opposed metal surfaces will be properly compensated and sealed, and to eliminate the highly heat wasting metal to metal contact which is now common in many installations.

By thus preventing the passage of heat from the one steel frame to the other, we are able to secure the structural advantages of metal frames without being subjected to appreciable heat loss therethrough. This applies particularly to sealing strip 44 but is also true of sealing strip 46.

Strip 44 is preferably placed around the entire perimeter of each window section and thus completely insulates the storm window from the i., casement window. In this way, not only is heat saved, but the inside window is permitted to assume the room temperature and the storm window will assume the outside temperature. This prevents condensation of moisture on the inside 21 window and window frame and thus prevents the now common spoiling of drapes and curtains due to such condensation of moisture on the metal frame of the inner window when the storm window and the maini window both include steel .,, frames which are assembled in steel to steel contact. In this way my window not only saves heat but eliminates a common cause of complaint against steel frame storm windows.

Particular attention should be called to the :3 section on the lines VI-VI as shown in Fig. 6 wherein is illustrated the meeting surfaces of the movable vent of the fixed part of the window.

The frame sections of the window are shown at 53 and 54 respectively and also shown is the :as slight overlapping thereof as is commonly employed in this sort of window to secure sealing between these portions. The frame sections 2 are here fastened in the usual manner to window sections 53 and 54, excepting only that it may be 4d necessary to employ bracket 38 to assist such fastening. It will be understood that bracket 38 may or may not be employed as needed.

Said frame sections 2 are fastened to window frame portions 53 and 54 in such relation to each other that when the vent of the window is closed. and section 53 is contacting section 54, the respectively opposed portions 36 and 37 will contact each other throughout most of their respective lengths. This will provide a wide 56 closely contacting surface seal between these portions of the storm window to insure against entry of any rain or wind therebetween. Obviously, sash sections 8 and 9 shown in Fig. 6 are held In position with respect to frame sec56 tlons 2 by either of the means above described.

Also, the sealing strips indicated at 44 and 45 in Fig. 5 may be used here, too, if desired.

Fig. 11 shows the side of the vent adjacent its hinges. This is substantially the same as the side already described and shown in Fig. 6, excepting that attention is called to the fact that with standard' casement hinges there will be experienced no difficulty in opening said vent and closing same again to a tight seal on the storm sash. Dotted lines A represent an ordinary position of hinges 6 and Ga with respect to the section of said Fig. 12, when said vent is closed.

When it is opened, the arm of each hinge fastened to the vent will assume a position such as that shown at B, while the arm fastened to the frame will remain in the position A. Observing the line of motion of said hinge, it will be evident that the portion of frame 2 indicated at 70 moves first directly away from that indi76 cated at 71 and then turns outwardly; and that the return to closed position will be the converse.

Hence, a tight seal will be made on the hinge side of the vent when same is in closed position.

Thus, by use of these relatively simple parts, a close seal can be secured entirely around both stationary and movable parts of the storm window.

Attention is also called to Fig. 7 showing a 4 +,i, 1 11th 4i t V TTT Tf .i L 1 Th Ina secAUton on e ne V - 0 JL S .. ,. s a section shows the manner of affixing the frame sections on the portion of the casement window at the bottom of its transom. Obviously, similar procedure can be employed at any other frame member in the casement window at which mutually immovable sections of the storm sash are to be mounted. This feature, of course, will have its widest application on very large windows wherein a single panel can not advantageously be used.

Fig. 10 shows a section similar to that shown in Fig. 7 but taken on line X--X of Fig. 1 to show the details of the vent sealing. Particular attention is invited to member 55 therein which is merely a U-shaped member of appropriate width and depth which is inserted into the opening which would otherwise exist between the upper extremity of the vent portion of the storm window and the bottom of flange T. Obviously, this will or will not be used according to the existence of space between the upper limit of the storm window and said flange. If used, it may be fastened by any appropriate means such as screws similar to those fastening the rest of the storm window frame. Obviously, a similar piece can be placed in the same manner at the bottom of the vent if desired or needed.

Referring to Fig. 9, it will be seen that the frame 2 can be cut out at points 19 and 20 to receive hinge brackets or other extensions from the otherwise smooth outer surface of the casement window frame. In the particular embodiment shown, the hinges 6 and 6a are assumed to be mounted on flanges fastened to the front of the vent frame and said cut-out portions TO and 20 are cut so as to fit closely over them.

Slight leakage may occur at these points, but if the cutting and fitting is done carefully, it will not be appreciable.

However, where an installation of highest quality is desired, it is evident that after the storm sash main frame is attached to the casement frame, all corners, joints, bracketed attachments (such as that including strip 38 in Fig. 6) and other points where leakage of air is conceivable may be puttied or caulked in any standard manner, and this will eliminate all possibility of leakage at any point. If the puttying and caulking job is carefully done, it is evident that it can be kept entirely out of sight from either the inside or the outside of the window.

It will be observed that by reason of the mounting of said storm window firmly onto the casement window itself, the storm window will possess all of the rigidity of said casement window, and yet its opaque parts be small to admit a maximum amount of light into the room. It will also be light in weight to minimize the load on the casement window hinges and mounting means, and it will require a minimum amount of material for fabrication.

It will be seen that while I have selected a particular type of domestic casement window as the embodiment of my invention for purposes of illustration, that the frame and sash sections disclosed and described can be varied to meet a wide variety of windows without alteration of these sections or of the technique employed in using them. The sections can be conveniently cut to fit any size window and in very large windows subdivisions can be readily made in the manner shown in Fig. 7. The movable vent can be either horizontally or vertically hinged with no difference in the installation of the storm window. With such flexibility and versatility inherent in my invention and the members used in comprising the same, it will be obvious that various modifications of the individual parts can be readily made without departure from the underlying concept of invention.herein disclosed.

Such variations- may (by way of example only, and not as inclusive enumeration) be found in further variations of the locking means represented by slide 43 on clip 28, by variations in the section of sash member 3, and its counterparts, wherein the same can be variously reinforced, providing only the frame section is substantially rectangular, or by using any of the many forms of hinges which will be found readily available. Therefore, excepting as the claims specifically limit otherwise, they will be construed to include these and the various other variations which will be found available.
