1 My invention relates to railway hopper cars and more particularly to individually operated doors for such cars.

1 One of the principal objects of the invention is to prevent such a door from sagging on its hinge pins.

Another object of the invention is to provide simple and reliable means for forcing the door to a fully closed position.

Another object is to provide simple and reliable means for freeing the door from engagement with its supporting hook.

A primary feature of the invention consists in having a portion of the reinforcing member which is secured to the outer face of the door project inwardly and engage the housing for the door supporting hooks so as to prevent the door from sagging.

Another feature of the invention consists in providing a door supporting hook with a recess in its outer end for receiving a pry bar to, force the door from partially closed to fully closed position.

A further feature of the invention consists in providing the reinforcing member secured to the outer face of the door with a flange extending outwardly therefrom, the flange having upstanding means affording an abutment for alever to pry a door supporting hook from engagement with the door. Other and more specific features of the invention, residing in advantageous forms, combinations and relations of parts, will hereinafter appear and be pointed out in the claims.

In the drawings, Figure 1 is a face view of a portion of the door when in fully closed position.

Figure 2 is a sectional view taken on line 2-2 of Figure 1. i Figure 3 is an enlarged view partly in section and partly in elevation of the door supporting hooks. Figure 4 is a detail sectional view at the inner ends of the hooks. I I

Figure 5 is a sectional view through the hooks Figure 6 is a sectional view ends of the hooks.

Figure 7 is a transverse cross sectional view of through the outer the hook housing and the associated door shoW- ing the hook l2 in engaging position.

Figure 8 is a similar cross sectionalview of Figure '7 showing the door in locked position. In the drawings, l represents an individually operated door which is hingedly mounted 6 Claims. (01. 105-308) along its upper edge (not shown) by hinge brackets 2. The door is of conventional shape having inwardly extending flanges 3 which, when the door is in closed position, are disposed in overlapping relation with a member 4 which extends around three sides of the hopper, the member extending beyond the forward edge of the floor or slope sheet 5 of the hopper to define the opening through which lading discharges from the hopper. Where this member extends beneath the floor sheet of the hopper, it is of angle shape having an outwardly extending flange 6 similar to the member which extends on the sides of the hopper and a downwardly extending flange I for connection to an angle member 8 which is rigidly connected to the floor sheet of an adjoining hopper to tie the hoppers together.

Secured to the outer face of the door is a reinforcing member 9 having an outwardly projecting flange Ill. The outer face of the reinforcing member affords a surface which is engageable by door supporting hooks II and i2 projecting through matched openings in the door and in the reinforcing member. The hook II is adapted to support the door in fully closed position, while the hook I2 is adapted to sup- .port the door in a partially closed position. 1

Both hooks are pivotally mounted within a housing [3 which is secured to the floor sheet 5 of the hopper. The top wall of the housing is preferably formed by downwardly diverging portions I 4 so that lading within the hopper will be shed onto opposite sides of the housing to discharge from the hopper when the door is open.

Rigid with the reinforcing plate and extending inwardly therefrom through the door itself is a flange 15 which projects into the mouth of the housing l3. This flange may be conveniently formed as a marginal flange of. the opening in the reinforcing member and, by

having the lower portion thereof project into and is adapted to overlappingly engage, the upperedge of the hook l2ufor supporting thedoor in partially closed position. It is apparent, therefore, that when the hook H is moved downwardly the hook 12 must move correspondingly and it cannot move upwardly until the hook H is free from engagement with the door. Hook ll may be advantageously locked in closed positiori by a cam orthe like ,iflwhichiis "rotatably-"mounted on a rivet 19 between an'outer face plate 20 and the reinforcing member 9.

In view of the manner in which the portion in overlaps the hook l2, it will, ot course, Joe,,,appreciated that so long as the cam is in engagement with the portion I! of hook H both" hooks are prevented from moving: upwardly.

At their inner ends, the' 'hooks' 'may beaconveniently mounted upon a sleeve 2| which is supported by a rivet 22. While tharivet 22 may be suflicient to support the pivoted ends of the hooks, each of them may be advantageously provided with a lug or the like 23, the outer .sisur face' ofrwhioh isuconcentricxwith the pivotal Maxis bf tl'l hODki andiaisi adapted toiengage the -fi'oor sheetaS.iilrrvthisimanner, the? rivet and i'-\sleeve-' 2 lliare: relieved from all strains incident .supporting; theiaripivotedv :ends' 'ofzathevhOQKS.
