Referring more particularly to the drawings, l0

I indicates a hopper of a railway car of any suitable construction, the hopper shown for' purposes of illustration comprising inner and outer side sheets 2, and 3 respectively, an end sheet 4, and an inclined oor sheet 5. The inner side l5 sheet and the end sheet aresubstantially vertically dlsposed while the outer side sheet inclines downwardly and inwardly and terminates in a vertically arranged flange 6. The hopper sheets may be secured together in any convenient 20 manner, such as for instance, by rivets 1 which pass through inturned flanges 8 with which the inner and outer side sheets are respectively provided and adjacent portions of the end and floor sheets which are overlapped by the iianges. l 25 Secured to the lower or discharge end of the Y hopper is a frame 9 which receives a sliding door I0 for closing the lading discharge opening of the hopper. Although the sliding door is disposed in a substantially horizontal plane, it is inclined slightly with respect to the horizontal so that it will tend to remain in closed` position. 'I'he door frame is provided with an opening conforming to the discharge end of the hopper and it is also provided with a plurality of walls I I, I2, I3, and I4 which are respectively secured by rivets I5 to the hopper sheets 2, 3, 4, and 5. The walls II, I2, and I3 of the frame are vertically disposed while the wall I4`which is secured to the floor sheet 5, is inclined upwardly so as to conform to the inclination of that sheet. The frame is provided with a lateral projection which extends outwardly beyondthe outer side sheet 3 of the hopper in which theouter end' portion of the door, hereinafter referred 'vo as 45 the door extension, is disposed when the door is in closed position. g This lateral projection has substantially vertical side walls I6 which, in etfect, respectively constitute continuations of the walls Il and I4 of the frame. Adjacent their 50 inner ends, the walls I6 are integrally connected by vertically spaced plate like portions I1 and I8 respectively. 'I'he upper plate like portion I1 which projects forwardly from adjacent the upper portion of the wall I2 of the door frame and 55 the lower plate like portion I 8 which overlaps the upper face of the door are preferably formed integrally with the wall I2.

Extending continuously around the lower portion of the frame, from the outer end of one of l the vertical side walls I6 of the frame extension to the outer end of the other of the side walls is a laterally projecting iiange IS which, in addition to rigidifying the frame, serves as convenient means to which a member 20 for supporting the sliding door I 0 may be secured. This member, like other parts of the door frame, is preferably formed as a unitary casting and it is generally of U shape, the arms of the U, however, being connected at a point inwardly of their free ends by a transversely extending plate like portion 2 I. The door supporting member is preferably formed with an upstanding rib 22 which engages the underside of the laterally projecting flange I9 intermediate its edges and with a plate portion 23 which is spaced below the ange I9 and projects on opposite sides of the rib 22. It will thus be observed that the door frame is provided with a door receiving groove which is .formed by a portion of the flange I9, the rib 22 and the inwardly extending part of the plate portion 23. If desired, the inner edges of the plate portion 23 which cooperate with the side edges o f the door may be formed with an upwardly extending bead or rib 24v on which the door slides. In order that suitable means such as a. boot indicated by dota and dash lines in Figure 1 by the numeral 65, may be removably attached to the door frame for receiving lading as it discharges from the I hopper, the door supporting member 2li may be integrally formed along one of its sides and along its inner edge with, a groove 25. This groove is formed by a wallt26 which is preferably disposed in the plane' of the rib 22 and which terminates in an 'inwardly projecting flange 21 spaced below the plate portion 23. The outer end of the groove 25 is' preferably closed by a flange 28 which depends from the outer edge of the plate portion 2I of the door supporting member and extends from substantially' one side of the member to the other.

By providing the door `supporting member with a relatively narrow surface, such as the upper end of the rib 22, for. engaging the underside of v. the flange I9, it will be appreciated that consupporting member with metal of suicient area to permit it to be apertured to receive rivets 29, for attaching it to the flange I9, portions of the rib 22 are enlarged as at 30 to provide bosses.

On the sides of the door supporting member which are provided with the groove 25, the bosses 30 are formed above and below the outwardly projecting part of the plate portion 23 while on the remaining side of the member, theposed within the lateral projection of the door frame.` The portion of the extension which is normally disposed beyond the outer edgeof the lower plate portion I8 of the door frame is formed with an aperture 32 for receiving a suitable operating tool or the hand of an operator so that the door may be easily moved. To rigidify this por-l tion of the door, it may advantageously be provided with a reinforcing member 33 having a plate portion 34 overlapping the upper surface of the door and secured thereto by rivets 35. The reinforcing member is formed with an opening which registers with the aperture 32 in the door, and surrounding the opening is a marginal flange 36 which depends into the aperture and' preferably engages portions of the door bounding the latter. This flange protects the portions of the door bounding the aperture from blows which may be transmitted to it in the event the door becomes difficult to move. Moreover, the outer edge of the door is protected from such blows, by forming the reinforcing member with a depending portion 31 overlaps the outer edge of the door and which terminatesV in an inwardly extending ange 38 overlapping the underside of the door. The ends of the portion 31 form shoulders or abutments 31' which afford convenient means to which blows may be imparted from a hammer or the like tending to shift the door sidewise for the purpose of loosening the door prior to being moved to open position. In order that the reinforcing member lmay be readily applied to the door, the portion of the marginal ange 36 nearestthe outeredge of the door is of less depth than other portions of the flange, as is clearly shown in Figure '1, and the upper surface of the inturned flange 38 is spaced a sulcient distance below the underside of the door so that the reinforcing member may be removed and applied tov the door by rotating it about a point adjacent the point of intersection of the portion 31 and the flange 38.

To lock the door in closed position, and thereby prevent it from accidentally opening while the car is in transit, a suitable locking member 39, such as a cam, may be employed. The locking member is preferably pivotally mounted and the pivotal axis thereof may be advantageously arranged so that the member will swing in a path transversely of the direction of movement of the door. The pivotalmounting or support for the locking member comprises a rivet- 40 and a bushing or sleeve 4I which encircles the rivet and extends into an opening formed in the locking member. The outer end of the bushing 4I is formed with an annular flange 42 which provides a seat for the head on the outer end of the rivet. The inner end of the rivet extends through a wall 43 which is formed integrally with the upper and lower plate portions I1 and I8 respectively of the door frame and which forms the forward wall of an inwardly opening recess with which the wall I2 of the frame is provided. This recess has side walls 44 formed integrally with and projecting forwardly from the wall I2 and the forward wall 43 of the recess integrally connects the side walls 44 adjacent their outer edges. l

The lower plate portion I8 and the plate portion 2| are form-ed with aligned openings 45 for receiving the locking member 39 and, for the same purpose, the door is formed with an opening- 46 which, when the door is in closed position, is adapted to register with the openings 45.- Thus when the door is in closed position the locking member 39 may readily pass into the openings 45 and 46 and thereby assume a position preventing opening movement of the door.

To protect the door and the door locking mechanism from rain, snow or the like and thereby prevent moisture and foreign matter from entering the hopper and damaging the lading therein, a hood 41 is associated with the hopper for housing the locking mechanism and the outer end of wardly from the top wall 48 to overlap the outer sides of the side walls I6 of the door frame. The inner edge of the hood is formed with a depending flange 5| which is adapted to overlap the inner face of a rib52 which projects upwardly from the front edge of the upper plate portion I1 of the frame. Int will thus be observed that the hood will eiectively protect the locking mechanism and the outer end of the door from rain, snow and the like and also other foreign substances which it is desirable to exclude from the hopper.

Although any convenient means may be employed for associating the hood with the hopper,

it is preferred to pivotally connect the hood di` rectly to the door frame. yThe pivotal connec-,

tion between these parts may be formed by integrallyeproviding the inner .end of the hood with spaced lugs 53 which are adapted to respectively cooperate with twopairs,oflu'gs 54 which project forwardly from and are integrally formed with the wall l2 of the frame above the upper plate portion I1 thereof. The respectively cooperating lugs of the frame and hood have registering apertures for receiving any suitable hinge pins such as cotters 55. As water and foreign matter are likely to collect on the upper surface of the upper plate portion l1, it is desirable in order to prevent the hinge lugs on the door and frame kfrom acting as a dam to retain such water and foreign matter, to provide sufficient clearance between the lugs and the upper surface of the plate portion, so that any matter which may collect on the latter may readily escape therefrom. This clearance may be provided by forming the end portions of the plate Il with downwardly offset portions as indicated at 56 and also by increasing the width of the plate, as indicated at 51, adjacent the offset portions.

When 'the hood and locking member are in operative position, as shown in Figure 1, it will be perceived that it is impossible to move the locking member into an inoperative position until after the hood has been raised. It will also be perceived that even after the hood and locking member have been moved into inoperative positions, it will be necessary to maintain the hood in such position so that an operator may easily grasp the door to move it to open position. To make it unnecessary for the operator to hold the hood in an elevated position while opening or closing the door, the locking member is so designed that when it is moved into an inoperative position, as indicated in Figure 3, it will engage the underside of the hood and support the latter in its elevated inoperative position. The underside of the hood may be conveniently formed with downwardly extending ribs 58 which are spaced transversely of the hood so that the locking member may be interposed between them. In this manner accidental disengagement of the locking member and hood is prevented while the door is being operated.

Considerable dimculty is often encountered in moving the door to a `fully closed position due to the fact that portions oi the lading, as it is being discharged, lodge in the grooves in which the door slides. The lading which accumulates in the grooves along the sides of the door does not hlnder closing movement of the door because it will be pioughed out as the door is moved toward closed position, but the lading which accumulates in the groove for receiving the inner end of the door seriously hinders proper closing of the door. T0 obviate this diillculty, the portion of the flange i9 forming the groove at the end of the door frame is provided with a longitudinally extending downwardly opening recess into which lading which may have accumulated in the groove may be'forced by the inner end of the door. Moreover, the inner end of the door is somewhat pointed as indicated at 59 so that that portion of the door may readily enter the groove even though the lading which may have accumulated therein may have become packed and, therefore, tend to resist penetration. To further assist the door in its final closing movement and to also seal the door along its inner edge, the underside of the latter is provided with a transversely extendingl strip 60 having a beveled portion 6I for engaging a similarly inclined or beveled portion 62 on the door frame. These beveled portions function as a wedge and insure intimate engagement between the door and door frame to prevent the escape of any fine lading 'from the hopper adjacent the inner edge of the door.

As it may be desirable to prevent unauthorized tampering with the hood 41,v means may be provided for receiving the usual car seals (not shown). This means may consist of upwardly extending lugs 63 formed o n opposite sides of the frame which are adapted to be. respectively interposed between pairs of lugs 54 formed on the hood. The cooperating lugs on each side of the hood and frame are provided with apertures 55 which are adapted to register when the hood is in closed position in order to receive a suitable seal (not shown). As long as one of the seals remains intact, it willbe appreciated that access cannot be had to the door locking mechanism nor can the door be moved to open position.
