DOOR GRAIN-CARS.
aomoa.
Specification of Letters Patent.
Patented Apr. 22, 1919..
Application filed October 31. 1916. Serial No. 128,673.
To all whom it may concern:
Be it known that I, MICHAEL J JOYCE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Doors for Grain- Cars, of which the following is a full, clear, concise, and eXact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to doors for freight or similar cars, and has for its object the provision of doors which are readily removable and replaceable, and which are adapted to properly hold grain or similar materials in place within the car.
A further object of my invention is to pro vide doors which may be mounted in place in sections one above the other, each section comprising a pair of door elements together forming an arched construction. My invention further contemplates the provision of a supplemental floor construction between the different vertical sections of the door, thus to make allowances for inequalities should the various vertical sections not ontirely be alined.
I will describe my invention more in detail by referring to the accompanying drawing, in which Figure 1 is a vertical longitudinal sectional view through a car illustrating a portion of the car body showing my improved doors in place;
Fig. 2 is a sectional. view on line 2-2 of Fig. 1; and
Fig.3 is a fragmentary sectional view on line -et of Fig. 2.
Referring more particularly to Figs. 1 and 2, I show a car 10 having the floor 11 and roof 12. This car has a door opening 13 extending the full height of the car, this door opening having the customary door posts 1 1, 14:. The car is designed to carry grain or other similar small materials, and in order to close this door opening, I provide a door consisting of the elements 15 and 16. These door elements are made so that at their meeting ends they. dovetail as shown clearly at 17.
The outer edges of the doors'ections 15, 16 are grooved throughout their length so as to embrace the inner corners of the door posts 14. Thus the grooved door edges in fitting over the corners of the door posts .14 will hold the door sections in place, the
pressure from the grain against the inner side of the arch formed by the door sections holding the door securely in place.
It will thus be seen more clearly from the plan view of Fig. 2 that the'door elements 15 and 16 supported at their grooved extremities directly upon the corners of the door posts 14 and interlocked at their meetmg extremities form an arched construction, thus making a secure closure for the car capable of withstanding the great pressure caused by the heavy grain or similar material with which the car is loaded.
The vertical height of the sections may be any size to facilitate proper loading. I have shown in Fig. 1 two vertical sections of closure, the lower section consisting of the door elements 15 and 16 and the upper section consisting of the elements 24 and 25, the elements 24 and 25 being the counter parts of the elements 15 and 16 except that they are of less height. As before stated, the number of vertical sections can be made any desired number to facilitate loading or unloading.
In order to properly superpose these vertical sections to avoid the possibility of leakage, I provide supplemental fioor elements 26, there being a supplemental floor element 26 between the vertical sections of door elements. The supplemental floor element 26 is laid on top of the door elements 15 and 16. It very frequently happens of course that due to severe handling the superposed vertical sections may not aline properly and the supplemental floor section provides a meeting place primarily to properly support the door elements placed on top of it and at the same time to obviate any difficulty due to non-alinement of these vertical sections. Furthermore, it is the custom when removing door elements, to place a crow-bar or similar instrument under the door element and thus raise it upwardly. The floor section 26' thus serves an additional purpose. After the door elements have been raised to permit the material back of them to flow out thereunder, it is a simple matter to remove these door elements. In order to hold them in place hooks 28 are provided, as readily apparent from Figs. 1 and 2.
From what I have thus described the advantages of m invention Will be readily clear to those siiilled in the art.
Havinghowever thus described my invention, What I claim as new and desire to secure by Letters Patent is:
A grain door for cars comprising two interlocking door elements forming an arch, saiddoor elements having grooved edges along their outer extremities adapted to engage the corner posts of the car door frame and interlocking edges at their inner ex-.
tremities whereby said door elements are maintained in position When pressure is exerted from Within.
In witness whereof, I hereunto subscribe my name this 24th day of October, A. D.
