Specification of Letters Patent.

Patented Feb. 11, 11919.

Application filed January 30, 1917. Serial No. 145,345.

To all whom it may concern:

Be it known that 1, WILLIAM J. S'rmLrNc, a citizen of the United States, and a resident of Elmhurst, in the county of Queens and State of New York, have invented certain new and useful Improvements in Window Constructions, of which the following is a specification.

My invention relates to window constructions and more particularly to that class of windows having a plurality of window sashes mounted therein in a horizontal row and which are adapted to swing horizontally while the planes of the sashes remain vertical during the swinging movement.

One of the objects of my invention is the production of a sash of the above character which shall be simple in construction and easy to operate and in which both sides of the window pane may be cleaned from the inside of the window and while the sash is in closed position, thus preventing drafts during the cleaning operation.

A further object of my invention is the production of a window having sashes of the character above described and provided with interlocking means attheir meeting edges so as to obviate the necessity of using muntins or other separating strips in the window.

A further object of my invention is the production of a window having means adapted to retain the sashes in closed position and enable them to successfully resist ordinary pressure such as wind pressure which in the absence of said retaining means or of a lock might blow open the sashes.

Tothe above ends my invention consists in the novel construction of window and sashes hereinafter more particularly described and then specifiedin the claims.

Tn the accompanying drawing:

Figure 1 is a horizontal cross-section taken through the window and sashes showin one of the sashes partly open.

ig. 2 is an enlarged horizontal cross-section taken through the window and sashes showing both sashes in closed and interlocked position.

Fig. 3 is a vertical cross-section talren throu h the window and one of the sashes.

Re erring more particularly to the several figures of the drawing:

1, 2 indicate the walls of a building in which are embedded the angle iron piecesfl,

4. To these angle iron pieces are attached respectively in any desirable manner the upright side bars or frames of the Window as indicated at 5, 6' to which are fastened re spectively the inverted U-shaped strip 7 and the U-shaped strip 8 the function of which will be presently described.

The sashes 9, 10 of which there may be any desired number, two being shown in the present case for the sake of illustration only, are respectively provided with window panes 11 and 12 held in position between the molding and the front face of the sash, as is illustrated, by putty or any other suitable composition. The particular manner of holding the window panes in position and the particular construction or form of molding used, however, forms no part of my invention. Each of the sashes is provided on one of its sides with a il -shaped strip as indicated at 13 and 14, which U-shaped strip may be made an integral part of the sash itself or may be a separate piece united in any manner with the sash. The opposite sides of the sashes 9 and 10 have united thereto the inverted til- shaped pieces 15 and 16 opening in the opposite direction to the pieces 13, 14.

Referring now more particularly to Fig. 3 in which one of the sashes only is shown, a description of the device will be confined for the present to the window and to that sash only, it being understood that both the sashes are identical in construction.

The sash is centrally and pivotally mounted on an upper pivot 17 and on a lower pivot 18. Pivot 17 is suitably fastened within a flanged channel strip 19 eatending horizontally the length of the window and the lower pivot 18 is secured in any desired manner to the lower frame 20 of the window. 11 tl-shaped strip 21 extending also horizontally the length of the window fits within the flanged channel strip 19 and is capable of a telescoping movement therein. The upper pivot 17 protrudes downwardly through an opening in the U- shaped strip 21 and through an opening in the upper wall of the top portion 22 of the sash. The lower pivot extends upwardly through an opening in the lower wall of the bottom portion 23 of the sash. A spring 2 1 encircling the upper pivot 17 bears against the U-shaped strip 21 causing said strip to exert a downward pressure against the sash.

It will be noticed that the U-shaped strip 21 has an inwardly curved base conforming in shape to the outwardly curved surface of the top portion 22 of the sash and that the lower frame 20 of the window on which the sash rests has an outwardly curved upper surface conforming in shape to the inwardly curved lower wall of the bottom portion 23 of the sash. It is therefore obvious that to open the sash a more or less firm pull is required in order to overcome the resistance of the spring 24 and also to overcome the resistance. due to the cam action which takes place and which is the result of the particular shape of the upper and lower portions of the sash and also-of those parts of the window cooperating therewith as has just been described. It is apparent for instance, that when the sash is opened a distance of 90, or in other words when it is opened to a position at right angles to that shown in Fig. 3, the lowest parts of the bottom portion 23 of the sash ride up and on to the barrier 40 of the lower frame 20 of the window and that the U-shaped strip 21 is in consequence forcibly raised an appreciable distance against the action of the spring 24. Because of the construction just described it is apparent that the sash has a tendency to remain closed or in that position shown in Fig. 3 and that a greater force is necessary than ordinary wind pressure to open the sash. This form of sash is very desirable for high windows or windows which are not easily accessible from the outside as no special lock, hook or latch is necessary to keep the sash normally closed.

From the foregoing description and from an inspection of Fig. 1, it is manifest that one or both of the sashes may, if desired, be swung around almost a complete half revolution or almost 180, so that when so swung the strip 16 bears against the strip 15 and the strip 14 against the strip 8 as shownin dotted lines in Fig. 1 and the outside of the window pane may be conveniently and easily cleaned from the inside of the window while the sash is in closed position. It is also obvious that because of the U-shaped and inverted U-shaped strips fastened to the sides of the sashes and to the side bars or frames of the window and each adapted to interlock with the adjacent strip, no muntins or other separating pieces are necessary for the sashes and if a l the sashes, of WhlCll there may be any number as has been explained, are swung open to an angle of 90 from their closed position, a maximum supply of light and air may be obtained. lhese interlocking means as described are extremely simple in construction and the sashes wit these strips may be made with so fine a deeeaace gree of accuracy as to render them practically air-tight.

It will be understood that my invention is not limited to the exact details of construction shown and described but various modifications might be resorted to without departing from the spirit of the invention as set forth in the appended claims.

\Vhat I claim as my invention is 1. A window having a plurality of centrally and vertically pivoted horizontally swinging sashes each adapted to interlock along its vertical edge with its adjacent sash when in closed position and means tending to retain said sashes in interlocked position.

2. A window provided with side frames and centrally and vertically pivoted sashes arranged side by side in horizontal alineclosed position, said sashes being adapted to be swung around horizontally so that the front and rear thereof will occu y substantially reversed positions, interloc ing means comprising a vertical U-shaped strip attached to either side of said sashes and adapted to interlock with the interlocking means or vertical U-shaped strip of the adjacent sash, said side frames being also provided with interlocking means comprising a vertical-U-shaped strip adapted to interlock with the interlocking means of the sashes adjacent said frames and means tendin to retain said sashes in closed and interloied position.

3. A window havin a channel strip em bedded in the wall at t e top thereof and extending horizontally the length of the window, a U-shaped strip fitting within said channel strip and capable of vertical movement therein, a plurality of horizontally swinging sashes arranged side by side in alinement and mounted on pivots fastened in said channel strip and extending through said U-shapcd strip said sashes being provided with means along their vertical edges adapted to interlock with each other when Said sashes are in closed position, a lower frame for said window having a curved surface on which said sashes are adapted to ride when being swun on their pivots and springs carried by sai pivots and engaging said U-shaped strip to cause the same to exert a downward pressure against the tops of said-sashes.

Signed at New York, in the county of New York and State of New York, this 27th day of January, A. D. 1917.
