Application led Mayl, 1922. Serial No. 564,780.

To @ZZ whom t may concern Be it known that l, BENJAMIN; 1W. Hurra, a citizen oi the United/States, residing,` at Brainerd, .in the Icounty of Crow `Wing and State of Minnesota, have invented certain new and useful :improvements in Grain-Car Doors; and l do hereby declare the followingto be a full, clear, and exact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same. y

The present invention relates to grain ear doors, and aims to provide a novel and iinproved permanent door structure tor `grain cars, to eliminate the use ot the temporary doors made or' boards nailed to the door trames tor retaining the Lgrain, sand or other material.

Another object is the provision of novel means for mountingr double or a pair oi doors to be disposed at an vangle with one another when closed, for withstanding the pressure of the grain ormaterial against same from within the car, and to provide a tight tit between the doors an d between the doors and door trame, so as to avoid leakage, said mounting,` enaolinp; the doors to be conveniently moved to open and closed positions.

With the foregoing; and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit yof the invention.

The invention is illustrated in the accompanying drawings, wherein F igure l is an outer elevation showing the doors in closed position.

Fig. 2 is an inner elevation with the doors closed.

Fig. 3 is a top plan view showing' the doors in closed position, with the door trame shown in section.

Fig. 4 is a view similar to F ig. 3 show ing, in iull lines, the position ot the doors when swinging them together or apart, and showing, in dotted lines, the doors swung;v into the car behind the lside wall thereof out of the way.

F ig. 5 is a similar view showingthe doors swung' outwardly.

The doors 'i' and 8 may be of wood, metal, or ot composite construction, and such double doors are jointly wider than the door opening, and the doors are hingedly mounted tor swinging and shifting movement about different vertical axes. rThe hinge mountings include Horrible hinges having the leaves Qsecured to the inner sides of the doors at their oliposite edges, leaves l() secured to the inner sides oi1 the door posts or jainbs ll of the door trame, and pairs ot' intermediate leaves l2 liingedly connected with one another and with the leaves 9 and l0. The leaves l2 can be doubled or folded together, and provide `for the shitting of the doors to different positions relatively to the posts itl, those edges of the doors adjacent to the posts being` capable of movement to diierent positions 'adjacent yto and around the posts.

Vertical cleats or stops 13 are secured to the posts ll for the opposite edge portions of the doors to bear outwardly against, the leaves or linlrs l2 straightening out as said edges of the doors are shifted outwardly against the cleats or stops i3, as seen in Fin'. 3.

The adjacent vertical enges oi the doors have means to iit together, for preventing leakage, includinnj a flange 14 extending at an obtuse angle :trom the tree edge portion of the door 8 to be disposed in the same vertical plane as the door i when the doors are in closed position, anda pair of strips l5 is secured to the free edge portion oft-he door 7 to provide 'a vertical zgroove l5 for receiving` said'iangge le, thereby providing' a snug; ntbetween the doors.

Fach oi the doors is provided at its lower end with a discharge or release opening 16 normally closed by an auxiliaryv door 17 hinged, as at 18to the corresponding main door above the opening 16, for the outward and upward swinging; movement ot the auX- iliary door to open position. Stops' 19 are secured to the inner sides of the main doors for preventingthe inward swinging movement or the auxiliary doors when in closed position.

ln using the doors, they are closed before the car is filled, and the doors are therefore swung outwardly within the door opening, and by swinging the doors and shitting,` them relatively, as suggested in Fig. el, doubling',` one or both of the hinged mount-- ings, the flange is can be inserted in the Groove l5', and the doors are then shifted outwardly along the adjacent sides ot the posts 1l to the position as shown in Fig. 3, with the opposite vertical edge portions of the doors bearing outwardly against the` stops 13 and the edges ot the doors abutting the posts 11. rThe doors will assumel an obtuse angle with one another, so as to converge inwardly from the door posts, as seen doors will press the opposite edge portions 4 of the doors tivhtl against the sto s 13 and CJ y i p 7 and to also transmit the pressure cured on the floor or deck the doors tending to straighten out will thrust the opposite edges thereof tightly against the jamhs or posts ll, to prevent leakage past the opposite edges of the doors,

` from the doors to the posts il, in order to effectively resist the tendency tor forcing the adjacent edges of the doors open outwardly. The

links or leaves l2 permit the opposite edges l of the doors to be swung and shifted to bear against the cleats or stops 13 and posts 1l. Before iilling the car, boards or cleats 2O are nailed or otherwise fastened on the door sill or floor along the lower ends of the doors to contact with the outer sides ot the doors, and assist'I in preventing outward displacement of the doors under the pressure trom the inside, and similarboards or cleats 2l can also be nailed or otherwise sebehind the doors, to prevent accidental opening of the doors `while the ear is being iilled. rlhe boards or cleats 2O also extend across the auxiliary doors 17 to prevent them trom being opened. The car is then filled by running the grain, sand j or other material over the doors through a chute, or the like. itting together tightly and fitting against the jambs or posts l1 tightly, will prevent leakage past the vertical edges, and the cleats 2O and 2l will also prevent leakage under the doors, as well as holding the doors closed. In order to start the discharge ot the material from the car, the cleats 2O are pried up and removed, which will permit the auxiliary doors 17 to swing open outwardly and upwardly, for the discharge of rIhe doors the material through the openings 16. After the material has been suiciently removed or loosened Jfrom behind the doors andthe cleats 2l loosened, the doors can be swung and'shitted inwardly, as seen in Fig. 4, to separate them, and the doors can then be swung outwardly, as seen in Fig. 5, for removinoj the remaining material from the fear. Aiter the car has doors can be swung inwardly behind the side wall out of the way,` as seen in dotted linesin Fig. 4.

Having thus described the invention, what is claimed as new is p l. A door construction comprising door post-s having stops, a pair of doors arranged when closed, at an angle with one another with their adjacent edges litted `together been emptied, the

and their opposite edges abutting the posts and bearing against said stops, and means for mounting said doors on the posts for the swinging movement ot the doors and Jfor the shitting movement of their opposite edge portions along the adjacent sides oi theposts to abut the posts and move against said stops.

2. A door construction comprising door posts having stops, a pair ot doors arranged, when closed, atan angle with one another with their adjacent edges fitted together and their opposite edges abutting the posts and bearing against said stops, and means :for mounting said doors on the posts 'tor the swinging movement of `the doors and for the shitting movement ot their opposite edge portions along the adjacent sides ot the posts to abut the posts and move against said stops, said means including pairs et hinge leaves between the doors and posts hingedly lcoiinected with one another and with the doors and posts and adapted to be doubled between said doors and poses.

ln testimony whereotl I have signed my name to this specification in the presence et two subscribing witnesses.
