My invention relates to car door mechanism such as is employed for maintaining the swinging doors of dump cars in closed position. The principal object of the invention is to afford a construction efliciently reinforcing a door locking mechanism involving a. sliding bolt element, to the end that the thrust or reaction of the door locking devices may be efliciently transmitted to the door when the latter is closed and subjected to the load due to the lading in the car.

The principal feature of the invention, generally stated, consists in providing a hinged car door with a spreader or stiilener which is secured thereto adjacent the free edge thereof, and in combining therewith a slidable bolt mounted upon the door and a locking member carried by the car body for cooperating with the bolt to maintain the door in closed position, the bolt being disposed so as to overlie a portion of the door spreader and the door having secured thereto in overlapping relation to the bolt a door stiflener which extends lengthwise in the direction of sliding movement of the bolt.

Another feature of the invention consists in providing the hinged door with a plurality of door stifleners extending at an angle to each other, one of the stifl'eners being secured to the inside of the door and the other upon the outside, and in combining therewith a slidable bolt mounted on the door and projecting between said stifleners and adapted to extend beyond the edge of the door so as to cooperate with a door locking member mounted upon the car body.

A further feature of the invention consists in providing a hinged door with a plurality of stifieners extending at an angle to each ried by the car body, whereby the door may be maintained either in fully-closed position or in partially closed position.

Other features of the invention relating to advantageous formsof construction and relations of parts will hereinafter appear.

While applicable to cars of other types,

door locking mechanism constructed in accordance with the invention is especially advantageous for maintaining the doors of hopper cars in closed position, and accordingly a car of that type has been illustrated in the drawings for the purpose of explaining the invention.

7 In the drawings, 1 indicates the side sheet of a car hopper and 2 is the hinged door for closing the hopper discharge opening. This door, which may be most advantageously formed of sheet metal and provided with marginal stifienin flanges, is adapted to swing to open posltion under the influence of gravity and may be hinged to the car bod in any customary or suitable manner. Pre

erably secured to the inner face of the door 2 is a door stiflener 3 extending at an angle to the hinge axis of the door. The stifiener 3 may be of flanged form, preferably an angle iron, and may be employed as one of the hinge straps of the door. Secured upon the outside of the door and extending parallel to the free edge of the latter remote from the hinge axis, is a door stifl'ener 4 which extends at an angle to the stifi'ener 3. When the invention is applied to a hopper car having hoppers disposed on opposite sides of the car, such as'is illustrated in my Patent No. 1,491,576, April 22, 1924, the stiffener 4 may serve as a door spreader for connecting the doors or door sections for respectively closing the hopper discharge openings. When connected by a door spreader the two doors in effect become one. The stiffener 4 is preferably a Z-bar whose downwardly extending flange 5 engages and is riveted to the door 2 and whose upwardly extending flange 6 is spaced outwardly from the plane of the door plate by means of the web 7.

Secured to the door in overlapping relation to the stiffener member 3 is a bracket 8 forming a guide for a reciprocating bolt 9. The lower end of the bracket is interposed between the door plate and the outwardly spaced flange 6' of the stiffener member 4 and is provided with flanges 10 which are perforated to receive rivets 11 serving to connect the bracket to the web 7 of the stiflener. The bracket is also riveted to the door plate and to the stiffener 3. The web 7 of the stiffener 4 is slotted to permit the bolt 9 to extend beyond the adjacent edge of the door.

At its lower end the slidable bolt is preferably stepped so as to provide a plurality of locking shoulders 12 and 13, respectively. These shoulders, as will hereinafter appear, are adapted to cooperate with corresponding shoulders with which the door locking member 14: carried by the car body is provided, whereby the door may be maintained either in partially closed or in fully closed position. The lower end of the bolt on the side opposite the shoulders 12 and 13 is beveled as indicated at 15 to cooperate with the inclined or rounded face 16 of the stationary looking member carried by the car body. When the door is swung towards closed position the cooperative engagement of the inclined faces 15 and 16 causes the bolt to be automatically lifted so that it may thereafter drop into door supporting engagement with the member 14. At its upper end the bolt 9 may advantageously be formed with an outwardly projecting lug 17 which is spaced somewhat above the upper end of the bracket 8 in which the bolt is mounted. This is a convenience in moving the bolt to unlocked posit-ion when the door is to be released, as a bar or any convenient tool may beintroduced into the space between the lug 17 and the top of the bracket 8 and employed to pry the bolt upwardly.

To prevent the bolt 9 from accidentally moving to a position permitting the door to swing open, a revoluble cam 18 is preferably mounted on the bracket 8 just above the upper end of the bolt. To allow the cam to swing without binding, it is journaled upon a flanged thimble 19 secured to the bracket 8 and to the door 2 and stiffening member 3 by means of a rivet 20. When the cam is driven downwardly against the upper end of the bolt 9 the latter is maintained in door supporting position.

The door locking member 1A is preferably mounted on the car body by being riveted to the angle iron stiffener 21 which is attached to the outer face of the slope sheet 22 of the hopper. The door supporting bracket 14 is formed with an opening 23 to receive the lower end of the sliding bolt 9, the outer wall of said opening being stepped so as to provide a plurality of shoulders or abutments 24 and 25, respectively, for cooperating with the corresponding shoulders 12 and 13 of the bolt. As will be readily understood, when the shoulder 12 of the bolt engages the shoulder 25 of the locking bracket 14, the door is maintained in partially closed position.

Because of the nature ofthe serviceto which cars of this character are subjected, the doors for closing the discharge openings of the hop pers frequently become warped to such an extent that while they may readily be caused to assume an approximately closed position, their complete closure is a matter of considerable difiiculty and requires the employment of a removable prying bar or lever. To enable the door to be readily forced from a partially closed to a fully closed position a perforated fulcrum plate 26 is preferably rigidly mounted upon the car body. After the door has been swung toward closed p0 sition until the shoulder 12 upon the bolt comes into locking engagement with the shoulder 25 upon the bracket 14, a prying bar or lever may be inserted through the hole in the fulcrum member and be brought into engagement with the door or with the door spreader 4 mounted upon the latter. By manipulating the lever the door may be forced inwardly to fully closed position, thus allowing the bolt 9 to descend so that its shoulders 12 and 13 respectively come into engagement with the shoulders 24 and 25 of the door locking member 14. The cam 18 may then be rotated so as to engage the upper end of the bolt and thus maintain it in door locking position.
