Patented July 20, 1937 UNITED STATES PATE oFicE 1 Claim.

This invention relates generally to windows of the type employing a plurality of sashes adapted to swing in a vertical plane.

It is an object of the invention to provide a window of the above type which will afford better ventilation, in conjunction with ease of manipulation. In this connection the invention is characterized by the fact that it utilizes at least two sashes carried by the frame, with the lower 1() horizontal edge of the upper sash spaced at a substantial distance above the upper horizontal edge of the lower sash. These sashes are so mechanically connected that when the lower sash is swung in one direction, as for example inwardly, the upper sash is swung in an opposite direction.

Another object of the invention is to provide a window of the above character, which will afford no unprotected open slots between the sashes, or between the sashes and the frame, when the sashes are swung to open position.

Further objects of the invention will appear from the following description in which the preferred embodiment of the invention has been set forth in detail in conjunction with the accompanying drawings.

Referring to the drawings:

Fig. 6 is a cross-sectional detail taken the line 66 of Fig. 2.

Referring first to Fig. 1, I have shown a window incorporating the present invention installed in the wall of a building. The window includes a frame In, which in this instance is of wood construction, but which may be of metal. Swinging sashes II and I2 are carried within the upper and lower parts of the frame I0, and between these sashes there is a separate sash or panel I3. The sashes II and I2 in this instance are shown in open position, with the upper sash swung outwardly and the lower sash swung inwardly.

Referring now to Fig. 2, the upper sash I I has its upper horizontal edge secured to the frame along along along 40 along for simple pivotal movement. By simple pivotal movementZI have reference to pivotal movement about a relatively fixed axis, as distinguished from swing movement about an axis which simultaneously slides in a vertical di- 5 rection. pivot pins I6 are provided (Fig. 3) which are mounted at the upper ends of the side frame portions I I. Plates I8 are secured to the upper side corners of sash ii, and are pivotally connected with the pin it. In order 10 to transmit swinging motion to the upper sash I I, and also for the purpose of retaining or sup porting this sash in a desired position, a pair of arms I9 are provided. The lower ends of arms I9 are pivotally connected to the side vertical portion ll of the frame. A suitable expedient for this purpose is illustrated in Fig. 5, in which plates 2 I, secured to the frame, carry pivot pins 22. These pivot pins in turn serve to carry the lower ends of arms I9] The upper ends of arms I9 have a pin and slot connection with the side edges of the s ash II. A suitable expedient for this purpose, illustrated in Fig. 4, consists in providing plates 23, which are secured to the side rails 24 of the sash II. These plates '23 are slotted, to slidably accommodate pins 26, which in turn are carried by the upper ends of arms I9. It will be evident from Fig. 2 that when arms 39 are caused to swing in a clockwise direction, as viewed in Fig. 2, sash II will be swung outwardly, while when arms I9 are swung in. a counter-clockwise direction the corresponding sash II is closed.

The lower sash I2 is shown provided with a mounting to the frame, similar to that described above for sash II. In this case, however, the lower horizontal edge of the sash is pivotally mounted for simple swinging movement, and the arms connected to the same (corresponding to the arms I9 for sash II) are inverted. Thus, the lower side corners of sash I2 are provided with pivotal connections 21 to the frame, and arms 28 (corresponding to the arms I9) are attached to the side rails of sash I2 by pin and slot connections 29. The pivotal mountings between arms 28 and the vertical side portions of the frame may be formed as illustrated in Fig. 6. Thus, plates 30, secured to the frame,'carry pivot pins 3|, to which the arms 28 are connected. In order to mechanically connect the two sashes II and I2, whereby they are caused to swing in unison in opposite directions, means are provided as follows:The side members of the frame are provided with recesses 32 which are normally covered by strips 33. Fixed to the lower ends of 55 arms H! are the crank arms 34, which are offset to be accommodated in the recesses 32. The lower arms 28 likewise have similar crank arms 36 secured to the upper ends of the same, which are offset and also disposed within recesses 32. Extending vertically within the recesses 32 are the adjustable connecting bars 31, which have their upper and lower ends pivotally connected to the

crank arms

34 and 36. The intermediate portion of each bar 3'! may be slidably engaged by a guide clip 38, which in turn is secured to the frame.

The intermediate sash 13 may vary in construction in different instances. It may be a panel rigidly carried by the, frame, or it may be mounted for swinging movement to be manipulated independently of the upper and lower sashes H and I 2. As shown in Fig. 2, its upper horizontal edge is pivotally connected to shoes 4|, which in turn are slidably carried by the frame, and it is retained in open position by the support arms 42. The upper ends of arms 42 are shown with pivotal connections 43 to the side rails of the sash, while the lower ends are shown pivot ally connected to plates 44. Such mountings, for independently operated sashes, are well known in the art and need not be described in'detail.

In order to insure that the sashes H and [2, when closed, will be relatively tight with respect to the frame, the strips 33, which extend the entire height of the frame, serve as stops for the side rails of the sash H, and also for the sash 13 in theevent this sash is mounted for swinging movement. The lower sash 12, since it is mounted for swinging movement inwardly, is cut away to clear the strips 33, as shown in Fig. 6. Filler members 43 are secured to the side portions of the frame and extend for the height of the lower sash IE to serve as a stop when this sash is in closed position. The lower edge of the upper sash I! can be provided with weather stripping 4's, and the lower edge of the intermediate sash 13 with weather stripping 48.

Operation of my window can now be briefly reviewed as follows:When the lower sash. i2 is grasped by an operator and swung inwardly, crank arms 36 are rotated in a clockwise direction, to cause upward movement of rods 31, which in turn impart clockwise rotation to the upper crank arms 34. Thus, arms l9 are rotated to swing the upper sash H outwardly. W'hen disposed in such an open position, air from the exterior cannot blow directly into the interior, since the opening between sash I l and the intermediate panel is generally downwardly, while the opening between the lower sash and the intermediate sash, I3 is generally upwardly. Thus good ventilation is afforded, and at the same time the openings are somewhat protected with respect to the direct entrance of rain. Closing of both the lower and upper sashes is likewise accomplished by manual swinging movement of the lower sash 12 to closed position, in which event motion transmitted through bars31 effects simultaneous closure of the upper sash II.

In connection with so-called awning type windows, in which a number of sashes are interconnected for simultaneous manipulation, it is common to have the upper rails of the sashes pivotally connected to shoes, which in turn are vertically slidable in the frame. If such a construction were modified to secure inward and outward movement of certain of the sashes, combined sliding and pivotal movement of the sashes would occasion formation of direct opening slots when the sashes were in open position. For ex ample, if the upper corners of applicants sash I I were pivotally connected to slidable shoes, upon opening of this sash an open slot would exist between the upper edge of the sash and the upper horizontal portion of the frame. The present construction obviates this difficulty, since ituses simple swinging movement relative to the frame for both the upper and lower sashes, thus avoiding such unprotected open slots.

I claim:

In a window structure, a frame including vertical side portions, a sash disposed in the upper portion of the frame, said sash having its upper horizontal edge pivotally secured to the frame for simple swinging movement of the sash relative to the frame, another sash disposed in the lower part of the frame, said last-named sash having its lower horizontal edge pivotally secured to the frame for simple swinging movement of the same relative to the frame, a pair of sashsupporting arms connecting the side edges of the upper sash with the vertical side portions of .the frame, another pair of supporting arms connecting the lower sash with the side portions of the frame, there being a substantial vertical space between the lower horizontal edge of the upper sash and the upper horizontaledge of the lower sash when both said sashes are in closed position, and vertically extending motion transmitting means interconnecting the upper set of support arms with the lower set of support arms, whereby when the lower sash is swung in one direction the upper sash is caused to swing in an opposite direction.
