BUS OR CAR WINDOW CONSTRUCTION Filed Aug. 24, 1955 Eig- 1.... E`E=E a i l Patented oei. 16, 1934 UNITED STATES PATENT OFFICE BUS R CAR WINDOW CONSTRUCTION Application August 2.4, 1933, Serial No. 686,535

4 Claims. (Cl. 18S-72) 'I'he present invention relates to bus or car window construction, and more particularly to an improved transom structure, an object being to provide a structure which will permit of the 6 convenient removal of the glass and side felt channels, -for replacement or other purposes, simply by the removal of the bottom rail of the transom. Another object is to provide improved spring means for supporting the transom glass in a way to effectually relieve it of the body or post movement, so that strains from such movement will not tend to break or loosen the glass.

With the above and other objects in view, an embodiment of the invention is 'shown in the accompanying drawing, and this embodiment will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

As the construction, according to the invention, is the same at each side, only one side will be shown in the illustrated adaptation of the invention.

In the drawing:

Fig. 1 is a fragmentary outside elevation of the transom structure according to the invention, and showing the upper portion of the movable window sash.

Fig. 2 is a vertical sectional view, taken along the line 2--2 of Fig. 1.

Fig. 3 is a horizontal sectional view, taken along the line 3-3 of Fig. 2.

Fig. 4 is a horizontal sectional view, taken along the line 4-4 of Fig. 2.

Fig. 5 is a reduced outside elevation of one end of the transom, the parts being shown in their assembled relation, and

Fig. 6 is a similar view showing the glass together vwith the bottom rail and side channels partially removed.

Similar numerals of reference will be used to denote like parts in the several gures of the drawing.

Referring to the drawing, 1 represents the side post of the window casing, and 2 denotes the top moulding, the latter being relatively narrower than the post 1 and having its outer wall disposed in flush relation with the outer wall of the post. The transom, according to the invention is disposed within the upper end of the frame in the plane below the moulding 2, as will presently more fully appear, and rearwardly of the transom the channel 3 for the movable window sash 4 is mounted on the post 1.

The top channel rail 5 of the transom is of inverted U-shape in cross-section and is connected to the under side of the moulding 2 by means of an upwardly projecting ange extension 6, ush with its inner leg and secured to the inner wall of the moulding by means of screws 7. A layer of cement 8 is interposed between the 60 moulding 2 and the top rail 5. A felt channel strip 9, for receiving the upper edge of the glass, is retained in the top rail by inwardly projecting anges 10 and 11 at the lower edges of its sides.

The side channel rails 12 (only one of which is 65 shown) are also of U-shape in cross section and are secured to the posts 1 by screws 13. A bowed leaf spring 14 is riveted or otherwise suitably secured in the base of the spring preferably having bowed extensions, as shown, extending upwardly and downwardly from a at intermediate portion. The inner wall of the side rail is provided at its end with a forwardly projecting lip 15 while the outer wall hasits end outwardly oset and folded inwardly upon itself, as at 16. The parts of the transom thus far described are xed with relation to the casing, while the parts now to be described are removable.

The glass 17 has its side edges contained in felt channels 18, and these channels are backed by a metal retaining strip which has a portion 19 that extends behind the channel and an outer portion 20 that extends along the outer face of the channel, the strip being clamped to the felt channel by flanging over its ends, as at 21 and 85 22, upon the inner and .front faces of the felt channel, the flange 21 being pressed into the felt so that it is ush with said inner face.

The lower edge of the glass is bound with glazing tape 23 and is inserted into the channel bot- 90 tom rail 24, which is of U-shape cross section and is provided upon the inner surfaces of its side with longitudinal ribs 25--25 that act as stops to limit the extent to which the glass may be inserted, and also reinforce the sides of the rail against the tendency to bow as the sides are sprung during the pressing in of the glass. The inner wall of the rail is provided with a dovetail groove 26 in whichis set a rubber sealing strip 27 adapted to engage the upper rail of the movable window sash 4, in the closed position of the latter. The glass together with the side felt channels and the bottom rail, are put in. place simply by sliding the side channels upwardly in the xed side rails 12 to a point where the upper edge of the 105 glass is rmly seated in the top felt channel 9, the bow springs being compressed and through pressure upon the portion 19 of the metal retaining strip pressing the felt channel 18 against the flange 15.

Angle retaining brackets 28 are thereupon se- -cured by screws 29 to the post 1 beneath each end of the bottom rail, and the transom is thus retained in place, it being only necessary to remove these brackets in order to remove the glass. Fig. 6 shows the manner in which the glass with its side channels and bottom rail is removed or inserted.

It will be observed that the felt channel 18 has its inner leg directly engaged with the retaining ange 15 of the side rail, while the metal-retaining strip 19-20 upon which the pressure o! the spring 14 is exerted is restrained only by the felt channel, there being nolimiting means upon the side rail 12 to oppose the pressure of. the spring upon saidstrip. The glass is thus eilectually insulated against the strain of body or post movements, and atight ilt is at all times secured irrespective of dimensional variations or changes due to shrinkage of the felt or other causes. Should the glass be broken it may be very easily and quickly removed and replaced without disturbing any other parts of the window structure.

I have illustrated and described a preferred and satisfactory embodiment of the invention, but it will be obvious that changes may be made therein, within the spirit and scope thereof,.as defined in the appended claims.

Having thus described my invention what I claim and desire to secure by Letters Patent is:-

In a window transom construction, a frame, a top channel rail secured in the upper end of said frame, side channel rails secured to the sides of said frame'having fixed inner and outer legs and open at their lower ends, there being a vertical free space beneath said lower ends; a glass sash, a bottom channel rail engaged upon the lower edge of said glass sash, said sash adapted to be vertically engaged with said side rails and said tcp rail through vertical movement in said free space, and removable retaining means secured to said frame beneath the ends of said bottom rail.
