Patented May 25, 1943 Application April 20, 1940, Serial No. 330,754 In Sweden November 27, 1939 6 Claims.

My present invention relates to a new and improved operating means for hinged or pivoted windows.

'The object of my invention is to provide an efficient and reliable device of the general kind tain other new and useful features which will be apparent from the following description of some embodiments of my invention with reference to the drawing in which:

Fig. 1 shows a partial perspective view of a pivoted window provided with an embodiment of my invention,

Fig. 2 shows a sectional view on the line II-II 0 in Fig. 1 but with the sash in closed position,

Fig. 3 shows a sectional View on line IIIIII of Fig. 1, and I Fig. 4 shows diagrammatically the arrangement of the operating means according to the invention.

In the embodiment of my invention illustrated in'the drawing a window frame I is provided with a window sash 2 mounted to pivot in said frame on horizontal pivots one of which is indicated by 3. In the hollow or recessed frame I,

pulleys 5 and 5 are rotatably mounted at the lower corners thereof, and other pulleys l and 8 are rotatably mounted in the side members of said frame I, as shown in Figs. 1 and 4. A roller 9 provided with an operating handle III is mounted rotatably in the bottom piece of the frame I and connected with a wire II which is pulley over the pulleys 5, 6, I, 8 in the way indicated in Fig. 4 or as indicated partly in Fig. 1.

As shown in Fig. 4 the free ends of wire II are each wrapped about roller 9 in opposite directions and secured thereto. Sufiicient length of each end of the wire is wrapped about roller 9 to provide for a linear displacement of the wire equal to the length of slot I5 for the purpose which will appear hereinafter.

In Fig. 1 the wire is associated with roller 9 in a slightly different manner in that the stretch of wire between pulleys 5 is wrapped about pulley 8 in a direction opposite that in which the wire is wrapped about pulley 9. If desired, separate wires I I may be used on opposite sides of the frame in which instance the ends of wires I I will position.

be wrapped about pulley 9 and secured thereto as in the case of pulley 9.

Two pins I2, I3 are secured to the wire I I in the positions indicated in Fig. 4. Each pin I2, I3 is provided with a head I2a and I3a, respectively, and said heads are slidably mounted in guides in the frame I, one of said guides being shown at I4, while the pin I3 projects through a slot I5 in the'frame and into a chute It in the adjacent surface of the sash 2.

In the embodiment shown the slot I5 is parallel with the longitudinal direction of the side frame member, while the chute I6 is inclined in relation to said direction, also when the sash is in closed It should be evident that the slot I5 need not be parallel to the side frame member, the main thing being that the slot I5 and the chute it are not parallel. Of course, both of them can also be curved more or less.

When moving the pin I3 upwards from the position shown in Fig. .1, it should be obvious that said pin I3 forces the sash to turn on its pivot 3 in a counter-clockwise direction, 1. e. towards closed position. The movement of said pin it. is effected by means of turning the handle I9, and from Fig. 4 it should be evident that the pins .I 2 and I3 are always moving simultaneously in the same direction. Thus, both sides of the sash 2 are simultaneously acted upon by the pins in one and the same direction and, since the movement of the handle I0 can be stoppedat any time,'the sash 2 can evidently be brought to a standstill in any position between the position shown Fig. l and the closed position.

The pivot 3, which is secured to the sash 2, canbe adapted to rest in a bearing in the frame which is open at the top so that the sash 2 can be opened further from the position of Fig. l by turning on the pins I2, I3, the pivot 3' thereby leaving its bearing and moving upwards therefrom. Said possibility of further opening the sash from the position of Fig. 1 can be secured also in other ways as, for instance, by making the end of the chute I6 open, so that the pin can move out of the same and the Way to be preferred is dependently largely upon the nature of the sash movement required and the pivot means utilized.

It should be obvious that several other modifications of the embodiment described are feasible within the scope of my invention. Thus, for instance, the mechanism described above as located in the frame could be provided in the sash, and vice versa. Furthermore, the inclination and shape of the slot I5 and chute I6 can be varied as found suitable. Besides, the wire H can be pulled over pulleys also at the top corners of the window and extend along all four sides of the window, pins being mounted on the wire at any point of said stretches for cooperation with slot and chute devices.

Instead of locating the mechanism comprising the wire, pulleys, etc. in the frame, as shown, it could be mounted in a special separate moulding to be attached tothe frame or sash as a unit. Of course, the roller 9 and handle It! can be located at any suitable point of the wire.

Furthermore, one or more sets of similar operating means could be used in a Window and operated by means of the same handle. For instance, one set could be used in the way shown in the drawing, and another set could be mounted in the same frame, or tube, and utilized for fastening and unfastening a screen or some other appliances. The last mentioned set could be combined with the same handle as the first mentioned, for instance, in such a way that said last mentioned set is connected to the handle by moving said handle inwards or outwards against the action of a spring,

It is to be understood, thus, that the embodiments and modifications described above must not be interpreted as in any way limiting the scope of my invention but just as exemplifications.

What I claim is:

1. In windows of the types comprising a sash mounted to turn in a frame, a chute in said sash, a guide in the frame, said guide and chute being in overlying edge surfaces of the frame and sash and forming an angle to each other, a pin slidably mounted in said guide for engagement with said chute, a wire connected to said pin, and operating means for moving said wire and there by displacing said pin along its guide in order to cause said sash to turn in said frame.

2. In windows of the types comprising a sash mounted to turn in a frame, a chute in said sash, a guide in the frame, said chute and guide being in overlying edge surfaces of the frame and sash and forming an angle to each other, a pin slidably mounted in said guide for engagement with said chute, a wire connected to said pin, pulleys rotatably mounted in said frame for guiding said wire, a roller rotatably mounted in the frame for operating said Wire, and a handle attached to said roller for rotating the same.
