ment. The sashes are further permitted to move to a limited extent in a lateral direction, sub-- stantially parallel to the plane which they occupy when in the closed condition. The dimensions of the parts and the arrangement of the seating surfaces are such that the two sashes coact in the manner of a toggle lever, so that when the meeting joint between the sashes, which represents the articulation joint of the toggle lever, is pressed inwards the force applied is transmitted, with great augmentation due to leverage,

in the plane of the sashes so asto press these latter very firmly together and against the window frame on both sides. A similar arrangement is also applicable to doors and to shutters for windows.

The bearings between the sashes and between the latter and the window frame which are effective as pivots during the final portion of the closing movement, and which serve as seatings in the position of closure, are not hinged or pin bearings but interengaging profiles running the whole length of the contacting parts, and consist for example of rounded profiles on the one part and corresponding channels on the other part. Thus at the end of the closing movement the sashes are very firmly pressed against each other and against the window frame throughout the entire length of the bearing surfaces, and therefore very tightly fitted. For the further swinging out of the sashes there are provided additional hinges which are specially designed to permit of limited movement of the sashes in a lateral direction as these latter approach the position of closure, so that the described closing action can take place.

Forms of construction embodying the invention are shown by way of example in the accompanying drawing, in which:

Fig. 1 is a diagrammatic section of a window in accordance with the invention.

Fig. 2 is a front elevation, partly in section, of the upper portion of the window shown in Fig. 1.

Figs. 3 and 4 are diagrammatic sections of modified forms of construction of the window according to the invention;

The window shown in Fig. 1 consists of two sashes I, 2 which are arranged to bear pivotally against each other along their abutting inner edges by virtue of the fact that the sash I is provided with a rounded edge 3 and the sash 2 with 5 a channeled edge 4. The outer edges of both sashes are likewise provided with rounded or similarly

shaped profiles

5, 5 with which they engage in

corresponding channels

6, 6 in the window frame. The sashes I, Z are additionally 10 1 pivoted to the window frame I by means of pins 8 which engage in slots in casings 9 let into the material of the frame, springs I0 being tensioned between these pins and the window frame.

In the meeting rail I2 there is rotatably mountl5 ed a bolt I3 which engages with its threaded end I4 in an internally threaded socket I5 attached to the middle member I6 of the window frame. A hand knob I1 is provided on the outer end of the bolt I3.

The mode of operation is as follows: When open, the sashes swing about the pins 8 as pivots. On the closing of'the window, the inner edges of the two sashes first come together, after which the rounded outer edges 5 move against the action of the springs Ill into engagement with the channels 6 in the side members of the window frame. If the bolt I3 be then tightened up, the two sashes act in the manner of a toggle lever, the pressure exerted by the bolt I3 in the direction of the arrow I8 being thereby converted into augmented pressure in the direction of the arrows I9 which presses the sashes very firmly together and against the window frame. This pressing ensures perfectly tight fitting of the window, which can be further improved by the provision of elastic packing means between the contacting surfaces. The slotted casing 9 serves to permit of the necessary final movement of the pivot pin 8, and the springs I0 keep these pins in position at the inner end of the slot when the sashes are being hinged in the open position.

Fig. 3 shows an alternative arrangement for per mitting of the lateral yielding of the sash hinge. In this case the hinge 20 attached to the sash 45 is connected to the window frame through the intermediary of a second hinge 2| which admits of the required lateral movement of the first hinge together with the sash during the tightening movement. 50

Instead of the described tightening by means of a tension bolt, the arrangement can also be such that, as shown in Fig. 3, a plain knob is provided on the meeting rail I2, and a stop 25 on the middle member of the window frame. 55

The sashes can then be pressed by means of the knob 24 slightly past the maximum spreading or dead center position up to the stop 25, in which position the inherent tension will retain the sashes in the tightened and closed condition without the necessity for any fastening means.

Fig. 4 shows how the hinge 2! can be replaced by a resilient connection 21 which likewise permits in a simple manner of the required slight lateral movement in the plane of the sashes. Fig. 4 also illustrates the manner in which a resilient counter-support 28 can be provided for the thrust end of the sash in the window frame. In this manner the fitting between the sash and the window frame can be still further improved without deviating from the mode of operation described in connection with the form of construction shown in Fig. 1.

I claim:

1. In a window, a frame, two sashes, slotted plates on the said frame at the corners thereof, pin hinges between the said frame and each of the said sashes, the pins of the said hinges engaging in the slots of the said plates to admit of limited movement of the said sashes in the direction of their main plane, corresponding abutting surfaces on both the side members of the said frame and the said sashes extending over the entire length of the longitudinal parallel sides thereof, the said sashes being together of a total breadth greater than the clearance between the said abutment surfaces on the frame when the window is open.

2. In a window, a frame, two sashes, pin hinges and spring elements between the said frame and sashes to admit of combined pivotal movement of the said sashes about their outer longitudinal edge and limited movement thereof in the direction of their main plane, corresponding abutting surfaces on both the side members of the said frame and the said sashes extending over the entire length of the longitudinal parallel sides thereof, the said sashes being together of a total breadth greater than the clearance between the said abutment surfaces on the frame when the window is open.

3. In a window, a frame, two sashes, pin hinges attached to the said sashes, further pin hinges interposed between the said first pin hinges and the said frame to admit of combined pivotal movement of the said sashes about their outer longitudinal edge and limited movement thereof in the direction of their main plane, corresponding abutting surfaces on both the side members of the said frame and the said sashes extending over the entire length of the longitudinal parallel sides thereof, the said sashes being to- 5 getherof a total breadth greater than the clearance between the said abutment surfaces on the frame when the window is open.

4. In a window, a frame, two sashes pivotally mounted in the said frame, corresponding abutting surfaces on both side members of the said frame and of the said sashes and extending over the entire length of the said members, the sum of the widths of the said sashes being greater than the inside clearance between the abutment surfaces on the side members of the said frame when the window is open, and the planes joining the center lines of the abutting surfaces on the said sashes being at an obtuse angle to each other when the window is closed.

5. In a window, a frame, two sashes pivotally mounted in the said frame, corresponding abutting surfaces on both side members of the said frame and of the said sashes extending over the entire length of the said members, and resilient packing means disposed along at least some of the said abutting surfaces, the sum of the widths of the said sashes being greater than the inside clearance between the abutment surfaces on the side members of the said frame when the window is open, and the planes joining the center lines of the abutting surfaces on the said sashes being at an obtuse angle to each other when the window is closed.

6. In a window, a frame, two sashes pivotally mounted in the said frame, corresponding abutting surfaces on both side members of the said frame and of the said sashes extending over the entire length of the said members, resilient packing means disposed along at least some of the 40.
