Application led April 15, 1921. Serial No. 461,475.

To a-ZZ 'whom it may concern.:

Be it known that I, JAMEs W. MCNEICE, a

4'citizen of the United States, residing at Ridgefield Park, in the county of Bergen and State of New Jersey, have invented new anduseful Improvements in Car-Door Con-4 structions, of which ication.

This invention relates to car doors and to the following is a speci- .some extent car construction.

yunloading of such commodity from the car;

to equip a car with a door of hingedly re lated sections, swingingly supported so'as to be movable intothe door opening, and out of the door opening to a point adjacent the top of the car; to provide a car with a door or doors having openings therein covered by slides which are movable to uncover the said openings to facilitate unloading operations, and means for holding the slides against movement in either of their positions. V`With these and other objects in view the invention resides in the particular provision, construction and relative, dispositions of the parts hereinafter more fully described and illusltrated in the accompanying drawing, in

which:

Figure 1 is a side elevation of a freight ,car equipped with a door of the present invention-a part of the car being shown.

Figure 2 is a vertical sectional view taken on the line 2-2, Figure 1.

Figure 3 is a horizontal sectional View taken on the line 3--3, Figure 1.

Figure 4 is a view illustrating the manner in which the door may be folded upon itself and be suspended at a point adjacent the top of the car.

At the outset it is to be understood' that freight cars usually'have door openings at the opposite sides thereof, and therefore a door constructed in accordance with the present invention will be arranged forvjuse at each of said door openings, It is als@ to Abe understood that the usual sliding or roll- In the drawing a part only of a freight car 10 is shown. The car 10 is equipped with the usual door 11 and has door openings, such as the door opening 12. Door jambs 13 are arranged at the door opening 12. The jambs are rabbeted to receive the side edges of the door 14. The door 14 comprises sections 15 and 16 which are hingedly connected together as at 17. The section 16 has openings 18 therein. Doors'or slides 19 are arranged to move over theopenings to close the same, and the slides are movableabove the openings to uncover the same. The slides 19 are arranged to move in guide ways formedby the use of strips 20 which are secured to the section 16. Each of the slides 19 has a handle 21 and a stop-lug 22. Arranged for swinging movement on the section 16 are latch members 23. An end of e-ach member 23 is hingedly connected to a bolt 24 carried by a bracket 25 secured to the section 16. The free end of each of they members 23 is provided with a slot 26. Securing devices 27 in the nature of latch elements are secured on the' section 16 and coact with the ends of the members 23 by virtue of the slots 26, that is to say, -by turning the part 28 of each of the devices 27 to one posltion',` the members may be held against outward swinging movementandby turning the part 28 of each device 27 to another position the members may Ibe removed from engagement with said parts 28. It

should now be obvious that when the slides v In order that the door 14 maybe swung in itsv entirety from one position to another,

the sectionl 15"'1 of the door has secured in place thereon members 29 by the luse of. straps 30. Each of the members 29 has an endangularly disposed portion 31 and the opposite end is connected to a rod or bar 32 attached to the top longitudinal 33 of theV car. It will be noted that the door14 does not entirely close the door opening 12 so that anular commodities such as grain may be loaded with the Well-known chutes over the top of the door.

lin order that the door 14C may be held or supported at a point adjacent the top 34 of the car, a swingmgly mounted member 35 is secured to the top 34C. As stated, the sections 15 and 16 of the door 14 are hingedly related, it should therefore be manifest that the sections 15 and 16 may be brought together in overlapped4 relation as shown in Figure 4r, and may be supported by the member 35 lWith the portions 31 of the members 29 in engagement with the said member 35. When in such position the door 14 is out of the Way to allow the car to be completely cleaned,y or the entire contents thereof removed; the door supported adjacent the top also allows thevcar to be used for transporting any other kind of merchandise.

lin 'order that the door may be locked from the inside against movement there is provided sliding bolts 36 which are carried y the sections of the door 14, and may be made to enter holes or openings in the jambs 13.

The door 111 is to be made preferably fromthin metal plates and it has been found desirable to employ braces 37 which may be detachably connected to the section 16 of the door and to the side of the car. Each brace 37 may include a turnbuckle 38.

What is claimed is:

A car door of the character described comprising a pair othorizontally hingedly connected sections normally arran d one above the other, the lower section being provided With spaced openings, strips secured to the side edgesof the openings and providing guideways, sliding doors arranged in the guideways, means for retaining the doors in opened or closed position -and said means being in the nature of latch elements including a bracket secured to the lower section between the openings, latch members hingedly connected to said bracket and provided vvith slots in their free ends anda latch element rotatably mounted upon each outer side of each opening to receive the slotted end of the latch members respectively.

lin testimony whereof l hereby amr my signature.
