Jan. 27, 1948. H. A. KAUFMANN STORM WINDOW VENTILATING AND CLEANOUT OPENING Filed March 11, 1946 INVENTOR HarryA/faufmann Patented Jan. 27, 1948 STORM WINDOW VENTILATING AND CLBANOUT OPENING Harry A. Klul'maim. Detroit, Mich. Application March 11, 1946, Serial No. 853,558 Claims. (CI- 98-99) This invention relates to an improvement in storm windows and particularly provides means by which a wide range of longitudinal adjustability is made available at the time of installing the window, a ventilating and cleanout opening is provided, and which also secures other advantages.

In the construction of storm windows, particularly those made with metallic sash and mounting frames, there has frequently been encountered difiiculty a d inconvenience in supplying ventilation through a storm window and in providing means by which dust and dirt accumulating on the window sill between the main windows and the storm windows may be swept out of doors. While these problems have been before reco nized and a number of devices suggested for solving them. they have always presented a certain amount oi complexity and the proposed solutions have usually disclosed a structure involving considerable expense to fabricate or inconvenience to use.

A further problem arising in the construction of storm windows has been to provide a window which could be readily fitted to window openings in a building with a minimum of individual attention to the dimensions and shape of a particular window opening. It is well known that the window openings of most buildings, particu- 3o larly those window openings supplied with wooden frames, are made to only approximate dimensions so that normally in the hanging of windows considerable adjustment must be made in each individual case. It is accordingly desirable 35 to provide means by which adjustment may be made around the entire periphery of the window opening for providing such adjustment.

Means to this end have been disclosed in my Patent No. 2,222,273, but it has been found de- 40 sirable to associate such means with ventilating and cieanout means as above outlined. Further, it has been desirable to provide substantially more vertical adiustability than is available in the structure disclosed in the above designated patent.

Accordingly, a major object of my invention is to provide storm window frame construction applicable, among other types, to wooden window 2 for ready sill level cieanout for the space between the storm window and the main window.

A further object of my invention is to provide a storm window as aforesaid having, in addition to the features named foregoing, means for providing ventilation through the storm windows without the necessity of opening a storm window Other objects and purposes of my invention will be apparent to those persons acquainted with articles of this type upon reading of the following disclosure and examination 01' the accompanying drawing.

In the drawing:

Figure 1 is a broken view of my improved window applied to a building having a wooden window frame and viewed from the outside of the building.

Figure 2 is a section taken on the line Iii-II of Figure 1.

Figure 3 is a section taken on the line IIIIII of Figure 1.

Figure 4 is a section taken on the line IV-IV of Figure 1.

Figure 5 is a broken end bottom view of the side frame and bottom closing structure.

Figure 6 is an inside oblique view of the side frame and bottom closure construction taken from the inside of the window and looking at the side frame element appearing on the left hand side of Figure 1.

Figure '1' is a section taken on the line VII-VII of Figure 1.

In providing means meeting the objects and purposes aforesaid I have provided a structure involving an expansible frame of the type disclosed in my Patent No. 2,292,273 at a top and both sides oi the window opening, wherein each of the said side frames extends to the bottom of the window aperture and terminates at the sill thereof. A fixed bottom closure of relatively large vertical extent and sufficient horizontal extent to constitute a sill for the lower periphery of the adjacent storm window is placed across the bottom of the storm window frame close to, but somewhat spaced from, the anticipated position of the sill of the main window with respect to the storm window frame. A movable botframes providing a wide range of longitudinal tom closure member is then placed in adjustable adjustability which can be readily utilized at the time of the installation oi the window.

A further object of my invention is to provide storm window construction as aforesaid providrelationship to a vertical portion of the just mentioned fixed bottom closure member so that it may be adjusted vertically as needed to contact the sill itself. Thus with the vertical side ing, together with the features aforesaid, means frame members being made as long as the window 3 aperture is reasonably expected to be, and said bottom closure members in their extended position being of sufficient vertical extent to equal the extent of said side frame members, the window frame may be placed within a window opening and with a considerable degree of freedom the said side frame members may be cut at the time and place of installation to fit that particular window opening. when such is done the said movable lower closure member will be adjusted accordingly. In this way with the adiustability provided by the lateral expansion on both sides of said frame and the vertical adjustability provided by both the top ansible frame and the bottom structure Just bed. the window frame may be made to fit a considerable range of window openings.

Referring now to the drawings in more detail there is shown a window frame i having a sill 2. side frame members I and I and a top frame member I. Placed in the usual position outwardly of the main windows are the blind stops I (Fig. 8) and to (Fig. '7). The storm window is placed as shown immediately outwardly of the blind stop and against the window frame members defining the window aperture.

The storm window frame comprises a pair of side members I and I. a top transverse member s and a lower transverse assembly it. elsewhere sometimes referred to as "lower closure members."

The general construction of these frame parts and the window or screen panels associated therewith are as is disclosed in detail in my said Patent No. 2,292,273 to which reference is hereby made. However, said parts may for convenience be here briefly described as follows.

The side frame member I (Figure 2) comprise a piece of sheet material, such as steel, zinc or aluminum, rolled into substantially a chair shape as illustrated providing an opening II between the outward sheet if and the inward sheet II of the flange ll of said frame member. Engaged with said frame member is an expansible sealing strip III contacting in sealing relationship the innermost sheet it of the frame member If by its inward flange fl and engaging the outermost sheet II of said side frame by it flange II, the extended end of which enters into and at least partially fills the said space II. The bight it of the sealing strip l5 engages the surface of the frame member 3 and is in any convenient manner, as by screws, fastened in sealing relationship thereto. Thus the frame member I may move somewhat toward or away from the frame member 3 as required according to the relationship between the storm window paneis and the actual dimensions of the window aperture defined by the window frame I', without breaking the weather seal existing between said frame member I and the sealing strip II.

The upper transverse frame member 9 (Figure 7) and the other vertical frame member 8 are constructed substantially the same as the vertical frame member 1 above described and are affixed to the adjacent parts of the main frame I in the same manner.

Window panels and II, or screen panels as the case may be, are mounted within suitable sash members, such as that indicated at 22, and are held in any convenient manner within the aperture defined by the storm window frame members above described. My said Patent No. 2,292,273 describing one completely satisfactory manner for holding those panels in operative 4 position. reference is hereby made thereto for further detailing thereof.

At the bottom of said window frame there is provided a transverse member ll comprising a fixed closure member 3! having a body part sheet II. a substantially horizontal sill sheet 32, the inward edge of which is turned upwardly to provide a weather guard It. This member extends the full distance across the window and has flanges If and 8! at each of its ends engaging the storm frame opening defining portions 2| and ll of each frame member I and a. Any suitable means, as screws 88, may be utilized to hold said flanges It and II rigidly with respect to the adjacent frame members.

The storm window sill 32 extends the full width of the'window and closely abuts the aperture defining sheets 24 and II of the respective side frames (Figure 6).

A movable closure member It comprises a single sheet of material bent in substantially a U-shape to engage opposite sides of the body part sheet II to hold itself in any adjusted position by frictional contact therewith. Said movable member-comprises an outer sheet ll, an inner sheet 42 the top of which is bent inwardly to form a ledge 43. This ledge is utilized for manual manipulation of the movable closure it up or down as desired. As best shown in Figure 8 said movable closure til extends across the window opening the full width thereof and closely abuts the flanges 34 and 35. The outer ends of the ledge 43 are preferably beveled somewhat as shown at 44 to provide ampl clearance between said ledge and the screws holding the flanges against the adjacent frame elements.

Referring to Figure 5 it is seen that the body part sheet ll of the fixed closure member 30 lies tightly against the inner sheet it of the flange if of the vertical frame member I. Thus while the movable closure member 40 extends the full width of the storm window aperture it does so only by its inner sheet 42, its outer sheet ll (Fig. 4) being cut oil at a point closely adjacent to the end of the flange II, as shown by the cut-out indicated at 45, in order to permit said movable closure member 40 to clear said flange.

It will be understood that wherein the above described construction has made express reference to only one side of the window, the construction so described and illustrated is repeated on the other side.

The lower sash 23 (Figure 4) sealingly engages the outer surface of the weather guard 33 to prevent the passage of moisture or air. Said weather guard being on the inward side of the sill any moisture in the region will tend to return to the outside. a

In assembling and dimensioning the various parts of this storm window, the flxed closure member III is afllxed to the respective vertical side members I and I at a substantial distance from their lowermost ends (Figure 6). This distance is equal to whatever is provided as a maximum extension of the movable member lll while permitting it to remain in operative relationship with the flxed closure member 80. As an illustrative but not a limiting example, if the movable closure member in is made to have one and one-half inch of overall vertical dimension so that it can extend approximately one and onequarter inches below the bottom'edge of the sheet II without impairing-its weather sealing engagement with said sheet ll, then the vertical frame members I and 8 will extend beyond the lowermost edge of the fixed closure member 30 approximately one and one-quarter inches.

The vertical frame members I and U are dimensioned with respect to the size of the window apertures into which they are to be placed so that with the upper sealing strip lBa fully extended, as shown in Figure 7, the lowermost ends of the side frame members will fit into the largest window aperture intended to be closed by their particular size of storm window. Thus as actual installation conditions vary from this maximum size, compensation can first be made by receiving the sealing strip ifla more closely within the upper frame member 9. When the flexibility permitted by this, which in a frequent but by no means the only possible construction is approximately onehalf inch, is fully utilized, then it is a simple matter for the installation workman in dealing with a still shorter window aperture merely to cut off the lower ends of the vertical frame members I and 8 sufficiently to enable them to contact snugly the upper surface of the window sill 2, and to move the movable closure member 40 up sulficiently to fit. Thus utilizing the illustrative but not limiting dimension mentioned above, with onehalf inch of adjustment available in the top frame member 9 and one and one-quarter inch of adjustment available at the bottom, there is provided one and one-half inch of vertical adjustability for the size of the storm window frame and still leaving one-quarter of an inch of sweepout and ventilating opening available at the lower edge of the storm window closuremeans. Other magnitudes of adjustment may be readily provided.

Lateral adjustment by manipulation of the side sealing strip l9 and its counterpart on the other side of the window are effected as described in my above named patent.

It should be understood that the particular structure herein illustrated and described is for illustrative purposes only and is by no means limiting. For example the sealing strip l9 may without changing the hereindisclosed invention be replaced by a solid piece of wood, metal or plastic, of substantially rectangular cross-section as illustrated in my Patent No. 2,291,726, without in any way changing the scope or application of the invention hereindisclosed. Other modifications and variations will be evident to persons acquainted with articles of this type so that the interpretation of the claims should be limited only as required by the express language thereof.
