The window is of the type shown in my pending application, Serial No. 162,645, filed Septemher '7, 1937, of which this application is a division.

I designates the framing of a car body around 3 and 4 designate, respectively, the sections of a window framewhich form a sash receiving channel, one section, as 3, forming one side of the channel, and the other section 4 being angular in cross-section and forming the other side and the bottom 5 of the channel. The section 3 may be an extension of 'the outer sheeting of the car body beyond the Wall a window opening as 2.

around the window opening 2.

6 designates a sash frame which may be of any suitable construction, its construction per se forming no part of this invention.

As the windows used in air conditioned cars are generally formed double, or with spaced apart glass panes l, the sash frame 6 is formed with a channel for receiving two glass panes in spaced apart relation. The margins of the glass panes are seated in a sealing and spacing strip 8. It is requisite that the space between the panes 1 be sealed to prevent clouding of the pposing surthe latch mechaference is had 2 Claims. (01. 292-42 clouding gas from between the glass panes l.

of the sash.

Sealing and insulating means are provided between the sash frame and the window frame. 1;

In Figure 3, 9 designates a channel-shaped sealing strip of compressible resilient material, usually rubber, to seal the sash and cushion the sash or the glass thereof against shock and internal strains and insulate it against transference of heat from the outside to the inside of the car and vice-versa. The sealing strip 9 embraces or encloses the frame 6 and the margins I!) extend beyond the inner edges of both the window frame and the sash frame and press against the outer faces of the glass pane l to further seal the joint between the glass panes and the sash-frame.

It is preferably secured as by cementing or other- The angular section 4 is hinged to the body along one side thereof, that is, along the top or bottom rail or one of the stiles, it being here shown as hinged along the bottom rail and the axis of the hinge is so located that when the sash is closed, the sealing strip or the side thereof adjacent the stationary side 3 of the channel of the window frame is compressed and also the other side compressed against the sash, that is, the entire sealing strip is under compression. Preferably, the axis of the hinge is located at or near the exterior angle of the angular formation of the movable section 4 of the window H designates the hinge, which is of the piano In so far as this invention is concerned, the

The quick releasable means is located between the edge of the sash and the opposing edge of the window opening or frame, it being here shown as interposed between the bottom flange 5 of the section 4 which may be considered part of the sash, and a wall of the window opening, it being preferably located along the edge of the sash opposite to the hinged edge, this being in the illustrated embodiment, along the top edge The quick releasable means here illustrated comprises a pair of latch plates I5 slidable fiatwise in opposite directions along the edge face of the top rail of the sash or of the section 4 and coacting with a keeper plate H on the window frame, or in the window opening and arranged fiatwise relative to the latch plates 15. One of 55 faces of the panes 1 or to prevent the escape of I dry conditioned air or of dehydrating or dethese plates is formed with cam or bayonet slots and the other with studs for entering the slots. As here shown, the latch plates are formed with slots I 8 extending lengthwise thereof and opening laterally at [9 through like edges of the latch plate, and the keeper plate I! is provided with studs 2| for entering and interlocking in the slots I8. The keeper plate I"! is secured, as by screws 22, ing through holes 23 in the keeper plate. The latch plates are secured to the sash or the frame section 4 by means of headed pins 24 exte1 1 ding through the lengthwise slots 25 in the latch plates and into the sash or the angular flange 5 of the frame section 4. The latch plates are provided with handles 26 at their opposing ends for sliding the latch plates endwise toward eachv other, and in so doing, causing the cam slots to move along the studs 2| and force or pry the sash outward slightly where it can be swung into wide open position, when the latch plates are moved far enough to permit the slots to move free of the studs. The outer margin of the latch plate is rounded or formed with a head 21 to close the crevice between the edge or" the sash and the frame member I.

In operation, when it is necessary to open the sash, the handles 26 are pinched toward each other, this operation sliding the latch plates l5 endwise toward each other, and thus forcing the sash slightly open about the hinge ll, due to the camming action of the slots I8 on the stationary suds 2|. When the latch plates I5 move into a position in which the studs 2| are at the open ends IQ of the slots l8, the sash may be swung open by applying a pulling force to the handles 26. In again closing the sash, the handles 26 are again pinched toward eachother, in order to aline the open ends of the slots 18 with to the frame I, the screws extendof the opening.
