MATTHEW J. FLANNERY, OF CHICAGO, ILLINOIS.

CAR-DOOR.

Specification of Letters Patent.

Patented Dee. 16, 1919.

Application led January 24, 1919. Serial No. 272,917.

To all whom it may concern.'

Be it known that I, MArrHEw J. FLAN- NERY, a citizen of the United States, residing at Chicago, in 'the county of Cook and State of Illinois, have invented new and useful Improvements in Car-Doors, of which the following is a specication.l

This invention relates to railway freight car doors, and more particularly to doors used on cars which are employed for hauling grain.

The invention has for its object to provide a strong and simple door of the kind stated, and also one which can be readily opened, and which, when it is closed, is securely held in this position.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing,

Figure 1 is an elevation of the door viewed from the outside of the car;

Fig. 2 is an enlarged section on the line 2 2 of Fig. 1;

Fig. 3 is an enlarged section on the line 3-3 of Fig. 2, and

Fig. 4 is a detail in latch member.

Referring specifically to the drawing, the door is composed of a series of superposed sections 5 positioned inside the car wall 6 and extending horizontally across the usual door opening 7 lined on its sides with j amb posts 8. The bottom section seats on the Hoor of the car. Each door section is reinforced by cross pieces 9 secured to its outer face, and by blocks 10 secured to its inner face, the former being positioned to come inside the jam-b posts 8 as shown in Fig. 2. The door sections are positioned back of the jamb posts 8.

The inner faces of the jamb posts 8 are lined by strips 11 on whichl are fastened the Shanks 12 of hooks 13, one pair for each door section 5. The outer ends of the shanks project from the jamb posts, and are shaped to form the hooks, the latter extending laterally of the shanks and being located opposite the ends of the door sections.

The blocks 10 have recesses 14 opposite the hooks 13 to house pivoted spring clip members 15. The clips have hook-shaped ends perspective showing a 16 adapted to engage the hooks 13, similar to latches and said hooks 13 therefore serve as keepers for the latches. To each clip or latch member is connected a releasing chain 17, having a ring 17a at its outer end said ring being located on the outside of the block 10. A pull on the chain 17 from the inside of the door, by means of the ring 17a, disengages the latch member 16 from the keeper 13.

The outer face of each door section 5 is fitted with rings 18 for facilitating handling.

To open the door, the uppermost section 5 is slid upward until the latch hooks 16 slip olf the keeper hooks 13. The top section is now free and may be dropped into the car or on the material therein so as to be out of the way and allow the next section to be pushed upward, and so on until all or as many sections as desired have been removed. If-the top section cannot be conveniently reached, a crow bar or other suitable tool may be applied to the bottom section of the door and all the sections slid upward until the latches are disengaged. An entrance to the car having been gained, the door on the other side of the car may be opened by drawing on the chains 17 to release the latches. It will be noted that the latch devices do not lock the door sections but merely serve to prevent the same from Vdropping rearwardly into the car. Outward displacement of the door sections is prevented by their seating at their ends against the same posts 8, and a lateral displacement is prevented by the cross pieces 9 and the jamb posts 8.

I claim:

The combination with a car wall having a door opening; of a door composed of a series of sections slidably supported in superposed relation across the opening and against outward displacement, latch devices at the ends of the sections for holding the same against inward displacement, keepers for the latch devices on the car wall, said latch devices and their keepers being inside the car, and the latch devices being pivoted for engagement with and disengagement fromthe keepers, and being also disengageable when the door sections are slid, and means located inside the door for releasing the latch devices.

In testimony whereof I aflix my signature.
