B Claims.

The present invention relates to an improvement in car window structure, particularly for I use in railroad passenger cars, busses, or the like, wherein the window is a ilxed installation, as

g distinguished from windows which may be raised which may be easily cleaned to provide a sash.

having rounded corners. Thestructure of the window opening as incorporated in the frame work of the car is such that the opening has square corners, and it is an object of the present invention to provide a combination frame and sash structure in which the window opening having square corners may have the sash having rounded corners tted therein in such manner as to provide a rigid, solid structure and one which is entirely nished in appearance. To this end it is-proposed in the illustrated embodiment of of sash structure in which the vframe may be formed of one piece of material if desired, and

will permit of the ready insertion of the pane of glass as well as its convenient removal in the event ci breakage.

a further object is to provide a structure of this character whichwillbe Weather-proof and en tirely free from looseness and rattling.

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

Fig.- 10v is a horizontal sectional View takeng along the line lill-i0 of Fig. 1.

Similar reference characters indicate correv sponding parts throughout the' several gures of the drawings.

Referring to the drawings the window framel`structure.'comprises ver-tical uprights lt-id disposed in spaced relation and defining the vertical edges of the windowopening, these uprights being shown as of T-shape in cross-section with the flange extending inwardly, but which may be of any suitablel form, an upper horizontal frame member ii of inverted Lvshape in cross-section, dening the upper edge .of the window opening, and a lower horizontal frame member i2, shown as formed of sheet metal bent upon itself at its upper edge, as at i3, the thickness of this upper portion of thelower frame member being substantially equal to the thickness of the vertical frame members liliii and the upper horizontal frame member ii. The upper frame member ii has secured to the underside of its outwardly projecting flange the base ilange of an outer sheathing it and to the upper side base flange of an inner sheathing l5. The lower frame member it is connected by an angular sheet metal member it to angle frame member i'i. extending horizontally of the car and upon which the sill. it is mounted at the upper side and the inner sheathing it is mounted at the inner side.

In each of the four corners of the window opening there is secured a corner ller member 2li having a rounded inner edge 2i. adapted to merge into the straight edges of the window opening and to conform to the corner oi the window sash, as will hereinafter more fully appear. The filler member is provided with a right anguiarly shaped outwardly projecting ilange t2 which extends beyond the edge of the window opening and is secured to the inner surface of the window frame structure by means of rivets 23. The outer surface of the insert member is ush with the outer surfaces of the vertical and horizontal members of the window frame structure, so that at the outer side of the window the frame structure, with the llers incorporated therein, presents a smooth, continuous and nished surface.

The window sash comprises a frame 24, preferably formed of one strip of material bent to shape and adaptedto have its ends joined centrallyss of the upper part of the frame, the cross-section of the material being such/v as to provide a U- shaped sash glass receiving portion, providing a channel 25 for receiving the edge of the sash glass, and an outwardly projecting flange 2i, the outer surface of which is continuous with theA outer surface of the channel portion, while the inner surface extends to a shoulder 2l forming the base of the channel portion. The sash glass 28 having rounded corners is provided at its edge with a U-shaped glazing strip 29, and is inserted into the frame by first spreading the sides of the frame, as shown in Fig. 4, the rounded corners of the sash frame permitting the latter to be readily inserted in this manner. The sides of the frame are then drawn together and are secured by a connecting strip 30 disposed in recesses 3l and 32 in the butted ends of the frame and secured by screws 33.

The shoulder 21 of the sash is slightly less in its dimensions than the window opening and is engaged and positioned in the window opening, as shown in Fig. 2, the flange 28 of the sash being disposed at the outer side of the window structure and engaging the outer surface of the window structure in surrounding relation to the window opening.

It will be noted that at the corners the flange of the sash structure is at the outer side of the flush surfaces of the vertical and horizontal frame members and the filler member, while the flanges 22 of the filler members are at the inner side of the frame structure, thus providing binding flanges at each side oi the frame which insure an absolutely rigid structure.

A weather strip 34 of felt, rubber, or the like, is provided upon the inner surface of the flange 26 and is tightly compacted between the frame structure and the flange upon securing the sash in place by means of the screws 35, which latter are engaged through holes 36 in the frame structure and screwed into threaded sockets 31 at the inner side of the flange 28 of the sash.v It will be noted that the screw heads are at the inner side structure, so that the sash may be assembled from the inner side and at the same time the outside of the Window structure is entirely free of screw heads, providing a window structure of very attractive and clear design at the outside, and one which prevents removal of the sash from the outside.

In practice the inner side of the window frame will be covered with suitable covering or sheathing, but as this forms no part of the invention it has not been illustrated.

While I have shown the sash frame as made of one piece, it will be understood that if desired it may be of any other suitable structure, as for instance a two-piece frame, in which case the two pieces of the frame may be joined together along the vertical center line of the upper and lower portions, in a similar manner to the joining of the upper portion as shown in the illustrated embodiment. Y

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