UN 117E CI-IARLEs n. nnnnus, or .irrinnisnuae, PENNSYLVANIA.

To all whom it may concern I i Be it known that I, Crmnrns Hr Annnus, of Harrisburg, in the county. of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Sliding Doors for Pressed-Steel Freight- Cars; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionvrel'ates to an improvement in sliding. doors for pressed steel freightcars, and it consists in the combination and arrangement of parts, and in the details of construction as will be more fully described and pointed out in the claims. I

In the accompanying drawings, Figure 1 is a View in side elevation of a section of a freightcar showing the doors closed; Fig. 2 is a view in section on the line 00 mofFig. 1; Fig. 3 is a view in longitudinal" section through the roof at about the longitudinal center thereof, and Fig. 4 is a view in horizontal section taken through the meeting edge of the door.

1 represents the side of a car, 2 the roof,

and 3 a side sill secured to the end sills and to the transoms a which support the floor 5. The roof is supported at its side edges by the eaves frames (only one of which is shown) each of which is composed of two angle bars 6 and 7 the former of which is L-shaped in cross section and the latter 2 shape. The lower flanges of the two angle irons 6 and 7 project toward each other as shown in Fig. 2, but are separated sufliciently for the passage of the upper. end of the door 15, and also to provide suiiicient space for ventilating the car. These angleirons are secured together by the bolts 9, and are held apart by the spacing sleeves 10, through which the bolts 9 pass, and they are also secured-to the side frames of the car. The side sills 3 are composed of two inverted L- shaped angle bars the horizontal members of which project away from each other, and they are separated and held apart from the free entrance and movement of the lower ends of the doors by the spacing blocks 11 held in place bythe bolts or rivets 12. The side frames 13 and 14 of the door opening in the car, are preferably formed of angle bars riveted at their upper ends to the lower flanges of the angle bars 6 and 7, and at their lower ends to horizontal flanges of the Specification of Letters Patent.

side sill 3. These side frames at each side of :the door are separated ufliciently for the free movements of the doors, and alsoto permit of the free passage of air between the frame and the door for ventilating the car. Where it is necessary or desirable to make the doorsair tight, as in refrigerator cars,'it can be done by suitable filler strips.

In order to permit of the. passage of air from the car to the outer air, or vice versa, I haveprovidedthe angle bars- 7, of the eaves frame, with. openings 1%,: located at intervals throughout the length of the car through which the air may freely pass from the car into the space between the angle bars 6 and 7 and also from the latter into the car.

1 While I have shown the car provided with in, closing, I may however use a single door r rnien I Patented Aug-10%, 1915. Application filedJune 10, 1314. Serial No. 844,229.

such asis now commonly used. The doors 15 each project at the top into the space between the anglebars 6 and 7, and at the bottom into the space between the sill members 3, thus absolutely preventing the possibility of any outward displacement of the door. Each member of the door is provided at its top, near each end, with the oppositely projecting angle plates 16,7each of which is provided on its lower face with concaved seats 17 for the roller 18, which latter move on runways on the top faces of the lower flanges of the angle bars 6 and 7.

One member of the door 15 is constructed at its inner edge as shown at 19, Fig. 1, to receive the inner edge of the other member, and said other member is provided with a stop 20 which limits the movements of the door sections toward each other so as to prevent them from becoming wedged together. Each door section is also provided with a handle 21, by which they may be moved to open and closed position, and the two sections are limited in the closing movements by the abutment 22 located in the eaves frame and in a position to engage the two members of the door at the top, thus preventing either section of the door from being drawn outwardly sufficiently to create an opening between the door and door frame.

' lVith this construction the doors may be readily and quickly moved to open or closed position. In open position they are closed between the inner and outer walls of the car body, and when in closed position they are positively retained against outward dislodgement or swinging-movement,

by the'slotted members of the car frame which receive respectively the upper and lower ends of the doors, and this is truein the event of breakage of any one ormore of the rollerbearing supports for the doors.

Again with this construction the'top and bottom'sections of the frame are so braced that the load cannot press outwardly and bind the door,, andthe roof truss prevents any outward movement of the hollow frame at the top.
