` hoppers.

16 indicates the side hopper-sheets, whose upper edges are riveted to the lower edges of the side walls, said side hopper-sheets being bent inwardly near their upper ends, as shown in Fig. 3, for the purpose of clearing the side sill. Brackets 17 extend from the side sill to brace these side hopper-sheets. These brackets, if desired, may extend continuously along the side sills opposite the side hopper-sheets. Curved angles 18 are employed. at the inner curved edges of the side hopper-sheets to reinforce and stiffen the same.

19 indicates the end'walls of the car, and 2O the inclined floor-sheets, which are supported by floor-supports 2l, arranged above the bolsters. These inclined floor-sheets extend down between the center and side hoppersheets and are riveted to inturned fianges 22 thereof, which preferably extend under said Hoor-sheets. An angle 23 is arranged under the inner edges of the inclined Hoor-sheets, said angle preferably extending entirely across the car or from side hopper-sheet to side hopper-sheet, as shown in Fig. 3. This angle not only serves as a stop, but also as a guide for the doors.

24 indicates a cross-ridge riveted tothe side wall of the car, the side hopper-sheets, and the inclined portions of the center sill. This cross-ridge is preferably constructed of two inclined plates, under the apices of which are arranged angles 25, while exteriorly-arranged angles 26 clamp the vertical partition and stiffening-wall 27 between them, said wall being also secured to the side wall of the car.

Riveted to depending flanges extending from the legs of the cross-ridge are curved plates 2S, said curved plates being also attached to the center sill and said side hoppersheets and forming the inner end walls of the The lower edges of these sheets are reinforced by angles 29, which preferably extend from side hopper-sheet to side hopper-sheet, said angles serving as guides for the door in a manner now about to be described.

30 indicates the doors, which are preferably reinforced by ribs of the frame-casting entering into their construction. These doors are shown curved to the contour of the curved edges of the hopper-sheets and in operation aredesigned to fit snugly between the angles 23 and 29, as shown in Fig. 1.

31 indicates hangers attached to the ends of the doors, which hangers are pivoted at their upper ends to levers 32. 33 represents the pivot-point of one these levers 32, which .is shown as a lever of the second order, and

34 is the pivot-point of the other of these levers 32, which last-mentionod lever is of the first order. It is of course understood that these levers are duplicated on each side of the car, there being hangers at each end of the doors. To the ends of the levers of the second order are connected rods 35, which #isses rods extend along the side sills and are connected to arms 36 on a rock-shaft 37. This rock-shaft is provided with a ratchet-wheel 38, with which coperates an operating-handle 39.

40 indicates a set of rods pivotally connected to the power ends of the levers of the second order referred to and also to the power ends of the second set of levers of the iirst order. The levers 32 are in this manner coupled and move in unison.

Assuming that the parts are in the position shown in Fig. 1, where the doors are closed, it is obvious that if the pawl is thrown out of the ratchet 38 the doors will drop by gravity to the position shown in Fig. 4, in which position the doors are beneath the angles 29.

Chains 4l have one of their ends connected to the doors, their other ends being received in two grooves, respectively, of a threegrooved sheave 42,' mounted in the center sill. This sheave is operated by a main chain connected to and wound about the third groove thereof, the other end of said main chain being connected to a rod 43,which rod extends, preferably,toward that end of the carat which the rock-shaft 37 is located, where it is provided with a chain 44, wound about a staff 45, having a hand-wheel 46. After the doors have been lowered to the position shown in Fig. 4 the hand-wheel 46 is operated to wind the chain on the staff and raise the doors inwardly to the position shown by dotted lines in Fig. 4, the doors swinging on an axis coincident with the pivotal points of their hangers. The load may thus be discharged through the exit-openings in the bottoms of the hoppers, (there are four of such openings, closed by two doors,) and when it is desired to close said openings the hand-wheel 46 is released, when the weight of the doors is sufficient to cause them to drop by gravity to the positions shown in Fig. 4, said doors being arrested in their lowermost positions by the angles 23. When in this position, the handle 39 is manipulated so as to rock the lever 32 and raise the doors to a position where they lit snugly between the angles 23 and 29 and in which position they eiectually close the hopperopenings.

The axes of movement of the levers 32 and the hanger-suspended doors are such that when the doors occupy their closed positions, as shown in Fig. l, these pivotal centers are slightly to one side of a'position of dead-centers, which tends to relieve the rods 35 and 40 of undue strains, but permits the doors to drop by gravity when the ratchet 38 is thrown out, as before described; also,when the doors are open, as shown by dotted lines in Fig. 4, these pivotal points are substantially in alinement, so that the chain-rod 43 and its connected chains are substantially relieved of all undue strains. It is of course understood that the pawl-and-ratchet mechanism can be employed in connection with the chain-staff,

doors will then drop to their lowermost posiwhich can obviously he placed horizontally instead of vertically for the purpose of holding the doors in their elevated positions; but as the doors are intended to occupy these positions only during the time of the discharge of the load the operator can conveniently hold the stad in this position 4during such period of time, which is comparatively short, as the car is practically self-clearing when the door The iion upon the release of the chain-wheel, when it is only necessary for the operator to manipulate the lever 39 to raise the doors to their home or normal positions.
