GRAIN-DOORS FOR RAILROAD-CARS.

Specification of Letters Patent.

Patented May *7, 1912.

Application filed June 2, 1911. Serial No. 630,933.

To all whom it may concern:

Be it known that I, JAMES T. W. LOE, a citizen of the United States, residing at Marshall, in the county of Harrison and State of Texas, have invented certain new and useful Improvements in Grain-Doors for Railroad-Oars, of which the following is a specification.

My invention relates to new and useful improvements in grain doors for railroad cars.

The objects of my invention are to provide vertically swingable double doors for grain cars, which are safe, economical and eflicient, and easy of operation and of universal application to all grain cars. And further objects are to provide doors which are adjustable on the inside of the car and capable of operation from within, and are easily removed, stored and replaced as required by the grain season. I accomplish these objects by means of the device illustrated in the accompanying drawings, in which Figure 1 is a view adjusted to a car door opening, with dotted lines showing the stay bar and the doors in an open position. Fig. 2 is a vertical sectional end view of the same. Fig. 3 is a view looking down upon the doors in position for use. Fig. 4 is a cross sectional view of the doors on a line where they lap in the middle.

Similar figures refer to similar parts throughout the several views.

Referring specifically to the drawings, 1, is an ordinary closed or box freight car with broken away ends, 2-2, and side door opening 3, through which the car is loaded and unloaded. The plates 4-4, are suitably secured by bolts, nails or screws to the interior of the car walls and extend flush with the door frame. They are of convenient width and of a length equal to the width of the doors, against which they swing, in the use-0f the device, as hereinafter detailed. The bot-tom of these plates are outwardly bent upon themselves, forming substantially U shaped troughs, 5-5, in which the doors move and rest in the use and operation of the device, giving to them strength and rigidity and preventing them from pressing out when grain presses against them when the car is loaded.

The double doors, 6 and 7 are of suitable material, preferably of metal, and are of sufficient length to extend across the door opening 3 and lap a sufiicient distance to give strength and rigidity to the same when in use, and are of a width to suit the conditions required. On the door operating on the inside, 6, a bend is formed, as at 8, similar in construction to the one on the plates and extending the length of the lap of the other door, 7 into which the latter door drops when the doors are to be closed. This bend or trough thus formed extends slightly over the edge of the door passing into it, and gives strength and rigidity, preventing it from sliding or slipping from side to side or settling below the margin of the door frame. On the door, 7 located outside of the door 6, is formed at its upper edge where it laps over the door 6, abend, as at 9, similar in construction to the bend on door 6 and the plates, 4-4, and adapted to fall over the upper edge of the opposite door 6, giving a stifiness and security to the top of the doors similar to that of the bottom, as heretofore described. The lower outside corners of these doors, 6 and 7, are slightly curved, as at 10-11, thus permitting them to swing up or down in the troughs 55 on the plates 4-4, in raising or lowering the doors to open or close the same as desired. In these curved corners are provided openings through which they may be suitably attached to the sides of the car 1, as at 12, by means of a pivot upon which the doors swing up or down in the use of the device. Ordinary hooks, 13-13' are conveniently pivoted to the door frame of the car opening 3, as at 14, and are provided for the purpose of gripping the upper edges of the doors 6 and 7 and holding them firmly in closed position. Usual and ordinary loop handles, 15-15, are suitably secured to the interior of the doors, thus providing a convenient method of manipulating the same. A bar or brace, 16, may be conveniently inserted in openings, as at 17 ,in the car door frame, which will add to the stability and rigidity of the doors when in use.

Having described the construction of the device, the operation is obviously as follows :After the device is attached to the interior of the car door opening, as detailed, by manipulation the doors may be raised or lowered, swinging up or down on the pivots, 12, closing or opening the same as desired by the operator, the lapping ends when lowered or closed, will enter the bends or troughs, holding the same in close and rigid relation. The bar 16 may be used to add further strength if desired. When the doors are thrown back in opening they drop into the trough or bends 55 on the plates H, and prevent them from going down below the margin of the door frame, and assist in holding the doors in an upright position. The doors may be made of any ordinary size to suit the width or height of the car door opening, and they can be easily removed for storage by removing the pivot 12 upon which the doors swing, and are equally as easy of putting back on the ear for use.

Having described my invention what I claim is 1. A device of the character described, consisting of a pair of plates having outwardly upturned lower edges forming troughs and means for securing the same to a car wall; and a pair of doors, each having a curved corner with an opening therein and adapted to pivotal attachment therethrough to the said plates; said doors being provided with upturned edges at their overdoors being provided with upturned edges at their overlapping ends and adapted to swing vertically in the car door frame, substantially as described.

In testimony whereof I aflix my signature witnesses.
