WINDOW CONSTRUCTION Filed May 23, 1955 2 Sheets-Sheet 1 INVENTOR. 6022Zie6 NuebeZ ATTORNEYS United States Patent '0 WINDOW CONSTRUCTION Gottlieb Nuebel, South Norwalk, Conn.

Application May 23, 1955, Serial No. 510,091

6 Claims. (Cl. 20-42) This invention relates to window constructions, and more particularly to windows having both slidable and swingable sashes.

An object of the invention is to provide an improved window of the type having upper and lower movable sashes, wherein by a single movement both the said sashes may be moved or shifted to open and closed positions.

Another object of the invention is to provide an improved window as above set forth, wherein one sash is of the slidable type and the other swingable or hinged.

A further object of the invention is to provide an improved window construction having a lower swingable sash and an upper slidable sash, which is so arranged and organized that swinging movement of the lower sash will automatically raise or lower the upper sash, thereby to provide for an advantageous double ventilation.

A still further object of the invention is to provide an improved two-sash window in accordance with the above, wherein both sashes may be swung to open position, the swinging of the upper sash occurring after it has first been slidably lowered.

Yet another object of the invention is to provide an improved window construction as above set forth, which is extremely simple and economical to fabricate, yet sturdy and reliable in its functioning.

A feature of the invention resides in the provision of improved chain or cord-operated actuating means for a window of the above type, which requires but little room and may be readily installed on existing frames.

Another feature of the invention resides in the provision of an improved window as above set forth, which may be utilized with a full length screen when such is desired.

Other features and advantages will herein after appear.

In the accompanying drawings:

Fig. 1 is an inside elevational view of a window construction made in accordance with the invention.

Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1, the sashes being in closed positions.

Fig. 3 is a view like Fig. 2 but with the sashes in open positions.

As shown, the improved window construction of the present invention comprises a frame having side members 11, a top member 12, and a sill portion 13. Mounted in the frame 10 are upper and

lower sashes

14 and 15, the upper sash being preferably of lesser height than the lower, and being downwardly slidable edgewise in the frame 10. Short guides 12a are provided in the upper portions of the frame 12, which are cleared by the sash 14 when in the open position shown in Fig. 3. The sash 14 may thus be readily removed from the frame 12, insofar as its mounting is concerned. The lower sash 15 is merely set in the frame 12 against guides 12b, and is swingable inward or to the left as shown in Fig. 3. For this purpose the lower member 16 of the frame 15 is provided with a stepped or shouldered edge engageable with a sill S of the frame 12, such engagement constituting in effect a hinged connection.

Referring'to Fig. 2 the

sashes

14 and 15 have

cooperable edge portions

14a and 15a respectively, provided with stepped interfitting configurations whereby a tight ing means are provided by which movement of one of the

sashes

14, 15 will result in opening or closing movement of the other sash. Thus an operator may swing inward the lower sash 15 and cause the upper sash 14 to slide, downward, and the opposite may also be done, thereby to readily effect and control an advantageous double ventilation through the window. In accomplishing the above 1 provide spring-charged means for normally holding the upper sash 14 in raised or closed position, said means comprising pulleys 18 secured to the upper corner portions of the frame 10,

lines

19 and 20 passing around the pulleys 18, and

springs

21, 22 and 23 secured to the lines and also releasably secured to the lower corner portions 24 of the upper sash 14 by hookand-eye or other suitable connections 14c. By the provision of the three

springs

21, 22 and 23 together with the pulleys 18 and lines 19 an advantageous soft or smooth-acting spring return is provided which is simple and economical to construct and reliable at all times in returning the upper sash 14 to the raised, windowclosing position.

I further provide pairs of

pulleys

26 and 27 at opposite sides of the frame 10 and on the lower portions thereof, and lines 28 passing around said pulleys and releasably secured respectively to the

sashes

14 and 15 by hook-and-eye or other suitable connections 14b and 15b. Preferably, as shown in Figs. 2 and 3, the lines 28 are secured to the lower sash 15 approximately half way between the top and the bottom of the sash, and are fastened to the lower corners 24 of the upper sash 14.

The

pulleys

27 and 26 are disposed one above the other, the lowermost pulleys 26 serving to reverse the direction of the lines 28 and the pulleys 27 co-operating with the pulleys 26 to enable the swinging movement of the lower sash 15 to be effective in causing longitudinal movement of the lines 28. The arrangement of the

pulleys

26, 27 and the lines 28 is such that when the sash 15 is swung inward as shown in Fig. 3 it will slide downward the upper sash 14, thus providing for double ventilation through the window. When the lower sash 15 is swung closed, the

springs

21, 22 and 23 will automatically raise the upper sash 14, enabling both sashes to become vertically aligned in window-closing position as shown in Fig. 2. By the provision of the separable connections 14b, 14c, and 15b, in conjunction with the removable mountings of the sashes, both the sash 14 and the sash 15 may be, without the use of tools, completely disconnected and removed from the frame 12 when desired, as for example in the case of fire, for repair or cleaning, etc.

When the upper sash 14 is lowered, as shown in Fig. 3, it may be readily swung inward as shown by the broken lines, being supported wholly by the chains or

lines

19 and 28.

In the above description it is intended that the term linesf includes chains, wire rope and other equivalent parts, and that the term pulleys includes sprockets,

rollers, V-pulleys and the like. In the drawings chains and sprockets are shown.

For the purpose of taking up slack in the lines 28 I provide springs 30 connected in the lines, and preferably keep the said lines continuous, with portions thereof (indicated at 31) extending between the ends of the springs 30. Thus, a positive drive is established between the lower sash 15 and the upper sash 14, while at the same time the flexibility provided by the springs 30 is had.

It will be understood that the usual one piece screen may be employed on the outside of the window, if such is desired.

I have found that my improved window construction as above set forth is simple and economical to construct, and reliable in operation at all times, and provides an advantageous means by which upper and lower ventilation may be effected in response to operation of only one of the sashes.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.

I claim:

1. A window construction comprising an upright frame; a pair of window sashes disposed one substantially wholly above the other when closing the frame and each sash closing a difierent portion of the frame, one sash being vertically slidable in the frame with a translational movement and the other sash being adapted to hinge on an edge of the frame; and means responsive to swinging movement of the said other sash away from the frame, for causing vertical sliding movement of the said one sash in the frame.

2. The invention as defined in claim 1, in which'the slidable sash is swingable away from the frame after it has been slid vertically downward in response to the said swinging movement of the other sash.

3. The invention as defined in claim 2, in which the frame has short guides, the slidable sash being swingable away from the frame after it has been shifted to open position and has cleared said guides.
