GRAIN DOOR.

Application filed December 4-, 1926. Serial No. 152,611.

This invention appertains to grain doors the or gates for railroad box cars, vehicle bodies and the like and the primary object of the present invention is to provide a grain gate or door which can be used a great number of times without injury thereto, thereby resulting in a saving of lumber and money as well as a saving of time and effort in removing the door or gate from its operative closed position. I

Another object of the invention is the provision of novel means for applying the gate in place, whereby the same can be effectively reused, the gate having pairs of swinging apertured steel plates at each end thereof for receiving the holding nails, the plates being so arranged as to be swung todifferent positions for different widths of door frames.

A further object of the invention is the provision of a novel grain door or gate including inner and outer skins or sections, which are so arranged as to provide a leak proof construction the ate also bein orovided .b N a.

with a novel outlet closure. r

A further object of the invention is the provision of a novel lock for the closure and novel means for permitting a car seal to be used with the lock or closure whereby tampering with the latch or lock can be readily discovered. 1

A still further object of the invention is to provide a leak proof grain door or gate of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture and one which can be placed upon the market and incorporated with a box car or vehicle body at a small cost;

With these and other objects in view, the invention consists in the novel construction. arrangement and formation of parts, as will be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a fragmentary side elevation of a box car showing our improved door connected therewith,

Figure 2 is a top plan view of the door showing the same in position on a box car, the car being shown in horizontal section,

Figure 3 is a central horizontal section through the improved door,

Figure 4 is a fragmentary elevation lookigg at the inside f he d or show ng ne f and swinging attaching plates connected therewith,

Figure 5is a detailed horizontal section taken on'the line 5-5 of Figure 1, and Figure 6 is a detail vertical section through the latch taken on the line 66 of Figure 1,

Figure 7 is an elevation of the gate showing the same in use on a wagon or truck body, and V Figure 8 is a plan view of the same.

Referring to the drawings in detail, where in similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates the improved grain door or gate and B. a box car with which the same can be associated. The box car B. is of the conventional type and includes the usual side wall 10 having the door opening 11 and the side frame bars 12. The gate A is preferably constructed from wooden strips and includes outer and inner skins or sections 13 and 14. It is to be noted that the strips 15 of the outer skin 13 run horizontally while the strips 16 of the inner skin run vertically. This provides a grain proof door or gate.

The door or gate preferably includes upper and lower sills or bars 17 and 18 andthese bars or sills extend beyond the front face of the door or gate. As shown the ends of the sills are notched as at 19 to provide shoulders 20. It is to be noted that the longitudinal walls oft-he notches 19 are flush with the outer face of the outer skin 13 of the gate. This allows the face of the door to be fitted flush up against the frame bars 12 of the 'door opening.

On the inner face of the door at each end thereof we provide pairs of attaching plates 21 and these plates are pivoted intermediate their ends to the door or gate by means of suit able bolts 22. The door itself on each side ofthe pivot point of the bolts is provided with spaced openings 23 and one end of the attaching plates 21 is provided with a nail receiving opening 24 which is adapted to he brought into registration with either one of the openings and by placing nails 25 in the openings, the gate or door can be quickly applied to different widths of frames and the attaching plate 21 forms means for receiving the nails for preventing the splitting of the gate or door and facilitate removal of the fas tening elements from out of the door frame.

The provision ot'the gate or door with the pairs of relatively spaced-openings23,,permits the door to be nailed to the "uprights of door openings of diiferent widths. When thegate or door -is-appliedtoa-door opening wider than -:the i one illustrated in the drawings, certain of the openings 28 will be located outwardly beyond or below the-uprights. These openings will becloscd bythe plates 21 to prevent the passage of water and ai t ough t em,,and,.the' ai w Pa s through the openings into the plates and the emain ng open ng ntheg rdoor.

"In accordancewithjtliis invention ,the gate orv door at a central pointiisprovided with, an

' enlarged outlet opening 26, which is adapted to be closed byz a suitable c'losure 27. This urei 27 i orme o er appi,ng boar the same as the body portion of the gate. This s re 2 is onnec ed to th ga e yuse f tabl h nges28- n rde t ma ntai ,Q1 S 1re27' in. its

' normal ,closed position we provide: a latch V I otedLlockingjplate 33 which,serves as means torpreven'ting the rocking of the latch bar from .outof engagement with the, keeper plates 51 andf32. This locking ,plate 33 is adapted to, receive aistaple 34: rigidly .6011- nectedwith the gate ordoorand a suitable tapered pin'35 is provided for fitting in the staple 3.4 whereby swinging movement of the locking plate 38 will be prevented and consequent swinging movementof the latch T bar 29. 'If preferredthe tapered lockpin dl'rcari'v be connected with the frame ot'a door by suitablefflexible means such as a cha1ni36. [T he lower free end of thispin has a trans- 7 Verse opening37' for the reception of a car seal 38. i

:"Iti's to ,be noted that the staple 34 .is carried. by an angular attaching base .plate"38 the'lower portion of which is arranged in horizontal plane and-provided with an opening in alinement',wi th.the staple 34 for receiving'thelower endof the tapered pin'35.

'7 -Fromthe foregoing descriptionQit can be seen that a grain car door has been provided which can be easily applied to and easily removed without appreciableinjurylto the door or door frame.

In Figures 7 and 8 we have shown the gate applied toa vehicle body C which-can be considered either;.-as,-a ,wagon ortluckiibody. This body can be of any conventional character-and is provided with upright stop cleats 40 at the rear endthercof against which the gate is adapted to be'fitted. The gate in this instance is of substantially the same .eonstruction as thegate or door previouslyidesigned and therefore adetail description thereof will notbe here given.

Changes in details may be made without departing from the spirit or scope ofythisinvention,-but what we claim asnQ lis:

.1. The combinationwith a car havingan opening and provided with spaced uprights at the sides of the opening, of a removable closure, including a body, sills secured to the upper and lower ends of the body and extending beyond thefront or outer side of the body, the sills being provided at their ends with notches receiving the uprightsand ,deep enough to permit the outer side ofthe closure to lie in full abutting contact witlrthc inner sides of the uprights,.and retaining'elqments passing through the body and engaging the uprights.

2. A removable closure for an opening in a car having uprights ,at the sides of the opening, comprising abody adapted to rest in full abutting contact, with the inner sides of the uprights and provided with pairs of spaced. openings. the openings of each pair being horizontally alignedand one opening of each pair'being arranged directly in rear of the-uprights, the other openings bein rarranged'laterally beyond the uprights, plates greater in length than the distance between the openings and pivoted centrally between their ends to the body at points centrally betwcenthe openings, the plates 'closing;the openings, laterally beyond the uprights and provided with openings registering with the openings directly inrear of the uprights, and elements passing through the openiugsimthe plates and the registering openings in the body and engaging the uprights.

In, testimony w iereof we afiix our signatures.
