DUMPlNG- CAR.

SPECIFICATION forming part of Letters Patent No. 425,607, dated April 15, 1890.

Application filed October 9, 1888- Serial No. 287,652- (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM W. GREEN, of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Dumping-Oars, of which the following is a full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of this invention is to secure the car-body to the bed-frame in such a manner as to readily permit of the body or divisions thereof being tilted and the load discharged on either side, as will be hereinafter set forth.

Figure 1 is a side elevation of a'car structure embodying my improved features; Fig.

2, a transverse section in plane 2, Fig. 1; Fig.

3, a broken-away detail of one of the standards supporting the Windlass-shafts; and Fig. 4, a sectional detail in plane 4, Fig. 3.

In the draWings,A represents the framingtimbers forming the car-bed. The body of the car consists of the three separate and independent compartments or boxes B B B pro- Vided at each end with hinged end-gates B B. These end-gates may be locked in place by means of the ordinary slide-bolt a, arranged vertically. The locking device consisting of the verticalbolt a, having the inner ends of the horizontal companion bolts (1 a pivoted thereto and the outer ends engaging with the sides of the box-compartment,is preferred, as it more firmly secures the end-gate in position, and is thrown into and out of a locking engagement by the vertical movement of theprincipal bolt a.

The box compartment or compartments forming the car-body may be tilted so as to discharge the load from either side of the car, as may be required, by means of the mechanism that will now be described.

The car-body or each boX- compartment thereof is hinged to the bed-frame at each side by the transverse lever-hinges O O. The alternate ends of these companion levers are attached to the under side of the car-body by the pivot-bolts a a (see Fig. 2,) while the opposite alternate ends are pivoted to the lugs a by the bolts a a the lugs being rigidly I bolted to the frame-timbers of the car structure. It will be understood that this system of lever-hinges is used in duplicate on both sides of the box-compartments. This arrangement and manner of attaching the car-body permits of the box-compartments being tilted from either side of the car, as shown in Fig. 2.

D represents a number of standards, (two being required for each boX-co1npartment,) the lower ends of which are properly secured to the car-frame, the upper ends terminating at some distance above the car-body, and supports the Windlass mechanism employed in tilting the body when discharging the load.

The upper ends of the standards D are provided with the horizontal rectangular slots 1), (see Figs. 2 and 3,) in which are placed the adjustable boxes 19', forming journal-bearings for the respective ends of the Windlass shaft or shafts D. Each of these shafts has winding-drums D D mounted thereon. The upper ends of the Windlass cables or chains D are properly secured to the winding-drums, the opposite hook ends 12 detachably engaging with the lugs 12 b, rigidly secured to each side and near the respective ends of the box-compartments, the hook ends of cable being shifted from the lugs at one end to the companion lugs at the other end, in accordance with the side of the car itis intended to discharge the load from, the Windlass-shafts having a corresponding movement in the rectangular slots b,

so as to bring the winding-drums into proper position and angle relative to the ends of the box-compartments to insure a more direct lift.

The Windlass-shafts have each a worm gearwheeld mounted thereon. The Worm-shaft d is provided with bearings d on the upper ends of the standards D and engage with said gear-wheels. The worm-shafts have square ends to receive the hand-crank d by which means the motion necessary to tilt the carbody is transmitted. By this arrangement the load may be discharged from either side of the car with the same facility. The nature and simplicity of the improvement are such that a special car structure is not required, but may be used on the ordinary platformcar.

The object of dividing the car-body up into a number of compartments is to permit of the load being easily dumped by hand. Where it is intended to employ power the car-body could be tilted as a whole with the same facility, It is also obvious that the improvement 2.
