WINDOW.

SPEGFICATION forming part of Letters Patent No. 664,993, dated January 1, 1901.

Application filed April 2, 1900.

To @ZZ whom it may concern,.-

Beit known that I, CHARLES CHMELITZEK, a citizen of the United States, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Windows, of which the following is a specification.

My invention relates to an improvement in windows of the type which consist of a frame containing two vertically movable sashes and each sash carrying an inner glass-holding swinging sash.

The novel features of invention consist:

First. In a locking device by reason of which the vertically-movable sashes may be locked against movement when their swinging sashes are opened, and, conversely, the swinging sashes may be locked when the vertically-moving sashes are movable, the object of this arrangement being, irst, to prevent injury to the glass in the swinging sashes, which is apt to occur by the sudden movement upward of the vertically-movable sashes when the swinging sashes are opened to their full extent, it being understood that when the swinging sashes are opened to nearly their full extent the weight of the swinging sash-frames and their contained glass will n0 longer resist the influence of the sash-weights tending to move upward the vertically-movable sashes, and, second, to prevent injury to the sashes by one part striking another, which is apt to occur if the swinging sashes are not firmly locked in their closed positionbefore the vertically-movable sashes are moved.

Second. In the employment Vin connection with the swinging sashes of devices normally out of sight and use, which when connected with the swinging sashes will limit their movement and prevent injury to them.

Third. In the use in connection with the swinging sashes of devices which will liniit the movement ofthe swinging sashes and which may be readily detached when a movement greaterthan that permitted by such devices is required.

The accompanying drawings will serve to illustrate my invention.

Figure 1 is a view in perspective of a window-frame, showing both swinging sashes opened and with the lower vertically-mov- Serial No. 11,271. (No model.)

able sash in its upper position and the upper movable sash in its lowest position. At the left of this iigure the frame is broken away to show the arrangement of adjustable 55V weights connected to the retaining-cords for the swinging sashes. Fig. 2 is a section v through the window-frame and one set of sashes, illustrating the vposition and relation of the locking device to the frame and sashes. 6o Fig. 3` is a section taken on the line X X of Fig. 2 looking upward. Fig. 4 is a transverse section on the line Y Y of Fig. 2. Fig.

5 is a transverse section through thelneeting-rails of the upper and lower vertically- 65 movable sashes, with their contained swinging sashes, with the window closed, the sec- -tion being taken through the middle of the sashes at the point where the spring-catch is located. Fig. 6 is a front view of the catch- 7o plate. Fig. 7 is a section of the catch-plate and limitingstrap.- This view shows' the limiting-strap about to be introduced and secured in theV catch-plate.

In the drawings similar numerals indicate 75 like parts throughout the several gures.

In the drawings, l0 represents a windowframe, which is of the ordinary construction. Located-within the window-frame and adapted to be moved by the ordinary cords and weights 8o are the vertically-movable sashes 1l lli. Y Situated within these sashes are the swinging sashes l2 12a. The swinging sashes are hinged at the bottom to the vertically movable sashes. Normally the swinging sashes 12 l2fJL 85 are held closed within the vertically-movable sashes by means of the spring-catches 13.

In Fig. 5 I have shown the construction of the joint between the frame of the upper ver,- tically-movable sash and its contained swingl9o ing sash, by reason of which the sash is made both wind and rain proof.

The swinging sash 12a is hinged, as shown at 14, to the vertically-movable sash 11', and the under surface 12b of the lower rail of the 95 swinging sash'12a is so formed as to overlap both the upper and outer surfaces 11b of the lower rail of the vertically-movable sash 11. This is accomplished by giving the meeting faces of the two sashes an inclination downroo ward from within outward and providing the lower rail of the swinging sash 12a with the depending portion 12u. I also construct the meeting faces of the swinging sash and vertically-movable sash in a similar manner.

Located on the top and on opposite sides of the top rail of the vertically-movable sashes 1l 11 are the double-action locks 15. These locks are countersunk in the top of the rail and consist, essentially, of a top plate 16, Fig. 3, carrying the studs 17, which support a plate 18, slotted at 19 and carrying the depending hook 20 and bolt 21. Movement is imparted to the plate 18 and through it to hook 20 and bolt 21 by means of a thumbpiece 22, which projects upward through a slot (not shown) in the plate 16. The hook portion 20 is adapted to take under a plate 23, countersunk in the top of the swinging sash 12. The bolt 21 is adapted to be passed into an opening in the plate 24 in the side of the window-frame. The operation of this doubleacting bolt will be readily understood.

I/Vhen the parts are in the position shown in Fig. 2, the swinging sash 12 cannot be moved outward, as it is retained by the hook 20 taking under the plate 23, but the vertical sash 11 is free to move upward. When the parts are in the position shown in Fig. 3, the swinging sash 12 is free to move outward; but the vertical sash cannot be moved upward, as the bolt 2l takes into the plate 24. In order to support the swinging frames, I provide the retaining-cords 25. These cords are located within the window-frame, as at 26 26a, and are retained therein and travel through a plate 27. They consist of a cord 25, on one end of which are located a number of separate weights 28 and at the other a catch-pin 29, which is adapted to take in the socket 30 on the front of the swinging sash 12. Preferably the plates 27 on the windowframe are screwedin position and ofa diameter sufficient when removed to permit the weights 2S to be carried out of the opening in the window-frame for the purpose of adding a greater or less number of weights to the retaining-cord to counterbalance the weight of the swinging frame.

For the purpose of normally limiting the outward movement of the swinging frames I provide the hinged strap 31. These straps are pivoted to the Window-frame by a plate, as at 32. The outer end of the strap 31 is provided with a pin with enlarged head which projects inwardly. 33 represents a plate countersunk in the said swinging sashes. At the bottom of the plate there is an opening 34- of the same diameter as the head of the pin on the end of the strap, and carried upward from this opening is a slot 35 of the diameter of the shank of the pin. Situated behind the slot 35 is a spring 36, which exerts outward pressure and which is turned backward at its upperend. It will be understood that when the head of the pin is placed in the opening 34 and then pushed upward the spring is pushed back until the head of the pin passes the spring, when the spring moves outward and under the head, thus preventing the head from moving down ward and holding the strap in position. To release the swinging frame, the pin is moved downward in the slot and then taken out of the catch.

A window constructed according to the foregoing description and as shown in the accompanying drawings may be readily cleaned with safety to the person doing the work. It may also be adjusted in various positions, as will be readily understood, in order to obtain effective ventilation.

Having thus described my invention, I claim- 1. In a window, the combination of a frame, a vertically-movable sash, a swinging sash hinged to said vertically-movable sash, anda lock carried by said vertically-movable sash, said lock consisting of a plate carrying a bolt and a depending hook, said bolt adapted to coact with the window-frame and said hook with the swinging sash, whereby when the bolt coacts with the frame, the swinging sash will be released, and when the hook coacts with the swinging frame, the vertically-movable sash will be free to be moved.

2. Ina window, the combination of aframe, a vertically-movable sash, a swinging sash pivoted to the vertically-movable sash, anda retaining device for the swinging sash, comprising a weighted cord, the weights of which are situated within the window-frame, and said cord provided with a catch-pin on its outer end adapted to coact with sockets on the faces of the swinging sashes.

In testimony whereof I affix my signature in the presence of two witnesses.
