said lever being provided with a handle K1 and having the rearward segmental portion L1, which is provided with the holes L2, either of which may be made to aline with a hole in each of the arms P1, so that a suitable pin, as L3, can be inserted in the alined holes for the purpose of locking the wagon-body at any desired inclination.
     N1 designates a pin which is attached to the arms P1 near their junction on which a roller is mounted which engages the walls of the slot M1, which latter is curved in substantially the arc of a circle, as will be understood from Fig. 1.
     Referring now to Fig. 3, the means for rotating the drum T1 will be described, said drum having the journal R1 provided with suitable bearings, said journal having mounted thereon the gear Q1, which meshes with pinion S1, which is mounted on the shaft U1, which is suitably supported, said shaft U1 carrying also the gear V11, which latter is in mesh with the pinion U2, which is mounted upon a shaft supported in any convenient manner, the outer extremity of said latter shaft having the squared portion W1 for the application of a wrench or crank X1, thereto, while the inner portion of said shaft is provided with a drum Y1, with which the lever Z1 is adapted to contact said lever being suitably fulcrumed and having a handle A2, whereby it can be used as a brake and thus retard the rotation of the drum Y1, and consequently the descent of the wagon-body, when desired.
     B2 designates depending arms or guides attached to the wagon-body, which are adapted to guide the same in its descent to its proper position between the sills B, as will be evident.
     The operation is as follows: The parts in their normal position appear as seen in the lower dotted lines in Fig. 1, the supporting arms P and V being substantially horizontal and the gearing on their abutting edges in mesh. When it is desired to raise the wagon-body, the drum T1 is caused to rotate by means of the gearing seen in Fig. 3, or other analogous mechanism, whereupon it will be seen that the chain S will be wound thereupon, thereby exerting a pull on the extensions Q, thus causing the cross-rod N to move toward said drum T1, said rod being guided in the tracks M. The arms P in the meanwhile also assume an inclined position, since a pull has been simultaneously exerted on the extensions U2, and the arms V being therefore raised from a horizontal position to the elevated position simultaneously with the arms P, it being remembered that the gearing on the ends X and Y of said arms is always in mesh, and if the rotation of the drums is continued to a sufficient extent the wagon-body will assume the position seen in full lines in Fig. 1, said body being kept horizontal by the insertion of one of the pins or locking devices L3 in its proper opening,

as L1, the cross-bar B1, always maintaining the same relative position by reason of its contact with the shoulder A1 of the head Z. When the wagon-body is in the position seen in full lines in Fig. 1, it will be evident that it can be rotated in any desired position upon the head Z, and that when the desired position is reached it can be tilted by imparting the proper movement to the lever J1, the body being further locked in any desired inclination by means of the pins L3. After the wagon has been dumped and restored to horizontal position it can be readily caused to descend to its inferior horizontal position k (seen in dotted lines,) the rapidity of descent being regulated by means of the braking-lever Z1, the parts finally assuming the position seen in the inferior dotted lines in Fig. 1.
    Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is--
     1. In a dumping-wagon, side sills with tracks thereon, a wagon-body, a head supporting a bar on the ends of which said wagon-body is mounted, two pairs of arms pivoted to said sills and having their upper intermeshing ends connected with said head, one of the said pairs having their pivotal connection with said sill movable in said tracks, and means for operating said pairs so as to raise said body.
     2.In a dumping-wagon, a truck with side sills having tracks thereon, two pairs of arms one pair of which is pivotally connected with said sills and the other pair being pivotally mounted having a sliding rod having heads in said tracks and having intermeshing upper ends, a head to which upper ends are pivotally connected, said head having a shoulder thereon with an upwardly-projecting stem, a bar on said stem and resting on said shoulder, and having its ends forming journals, a wagon-body with depending boxes in which said journals have bearings, a drum mounted on said sill, and a chain connected at one end with said drum and passing around a pulley on an extension of one of said arms and connected at it other end with an extension on another arm.
     3. In a dumping-wagon, a head a wagon-body rotably and pivotally supported thereupon, a plurality of supporting-arms pivoted to said head, and having intermeshing gear-teeth thereupon, a fixed fulcrum for one set of arms, a movable fulcrum for the other set of arms, and means for actuating the latter.
     4. In a dumping-wagon, a wagon-body mounted on a shaft or bar, the arms G each having an end secured to said bar, the other ends being connected by the pin H1, the lever J1 fulcrumed on said pin, and having a handle and a rearwardly-projecting portion L with the slot M1 and the holes L2 therein, the arms P1 depending from said wagon-body and having holes therein corresponding to said holes L2 and a pin N1 with a roller therein working in said slot.
     5. In a dumping-wagon, a wagon-body with
