Be it known that I, ABRAHAM L. YOUNG, a citizen of the United States, residing at Paris, in the county of Edgar and State of Illinois, have invented a new and useful Improvement in Dumping Apparatus for Vehicles, of which the following is a specification. y

My invention relates to means for transporting and quickly delivering a great variety of loose materials, and is adapted to service in railway as well as common road cars and wagons, my object being to provide aconstruction giving a high eficiency at a moderate cost, the saine being fully described liereinafter and is fully illustrated in the accompanying drawings, in whichl Figure l is a bottom plan of a common wagon-box bed, showing some of the principal parts of my dumping attachment. Fig. 2 is a transverse section on broken line A B, Figs. 1 and 5, to illustrate the position of the operative parts when in the closed state. Fig. 3 is the same section as Fig. 2 with the parts in the open position. Fig. 4 is a bottom plan of one of the dumper-shutters to more clearlyillustrate the construction. Fig. 5 is a side elevation of the wagon-bed to illustrate means for operating the dumping-shutters. Fig. 6 is a plan of the wagon-bed to illustrate several principal operative features not shown in Fig. 1, such as the top appearance of the dumpingshutters and other parts which form the bottom of the bed. Fig. 7 is an elevation of the front end of the bed, showing levers for operating the dumping-shutters. Fig. 8 is a cross-section on broken line E F, Figs. 1 and 6, which is close to the front bolster, to show position of the side slots in the dumper-sliutters to permit the latter to fall to the open position astraddle the holsters as in Fig. 3.

Similar numerals indicate like parts throughout the several views.

The drawings show the common road-wagonbed form of this dumping apparatus, in which l and 2 are holsters and 3 and 4 the vertical sides of the bed, in each of which latter is a series of grooves 5, which are wide and vertically disposed. In each side also is a longitudinal groove crossing the grooves 5. and in each longitudinal groove 1s mounted in `margins of the duiiipei-shutters.

bearings a long shaft 7, which is bent into a series of double cranks 8, which occupy the wide vertical grooves 5, the cranks being adapted to assume by turning the handle-arms 9 at the front end of the bed, Figs. 5, 6, and 9, either the Lipper or lower positions, as shown in Figs. 2 and 3, the handles being held in the lower position locked by being sprung under pins 9. Each of these cranks has loosely attached thereto the upper end of a vertically disposed connecting rod 10, the lower end beingloosely in engagement with the outer end of a clip 11, projecting from 'the outer sides of the dumping- shutters 12 and 13. The length of each rod is such that when the cranks 8 are in a raised position the shutters will be closed, with the rods each extending substantially across the axis of the crank-rod, thereby forming dead-centers and automatically locking the shutters in their closed position. Longitudinall y disposed there is secured at the ends of the bed, at the center of width, the ends of a strip 14, which has a triangular cross-section, Figs. 2, 3, and 8, the strip being so disposed that one of the points or angles is at the top to prevent lodgment of material being dumped. The duinping-shutters are each pivotally attached at the bottoni ends of the bed at 15 at about one-third the distance of the triangular strip from the inner faces of the sides of the bed. There are long strips 19 and 2O secured to the inside surface of the bed, which serve to close the outside There is a close-fitting strip of elastic or pliable material 21 secured to the ends of the dumping-shutters to prevent leakage of [ine materials, yet not prevent the easy movement in opening or closing the shutters. The dumping-shutters are each slotted about two-tliirds across their width from the outside, or to a point substantially in line with the pivotal points at 15, as plainly indicated in Fig. 1, to straddle the holsters when being turned to the position shown in Fig. 3, and these slots may be bordered with flexible strips similar'to end strips 21, but secured to the bottom faces of the shutters against the bolster side faces to prevent leakage in the slots.

In operation the dumper-sliutters 12 and IOO 13 being closed, as shown in Figs. 1, 2, 6, and 8, and the bed filled with loose material the latter may be dumped by disengaging the levers 9 and pressing them forwardly from engagement with pins 9, when by virtue of the upward and outward movement of the levers and the weight of the materials in the bed the dumping-shutters are made to assume the position shown in Fig. 3 and the material permitted to pass downwardly, as indicated by the arrows in Fig. 3. By reversing' the movement of levers 9 it is obvious that the dumping-shutters will be turned to the nearlyclosed position when the levers 9' are sprung forwardly and downwardly, and then they spring inwardly in engagement with pins 9, and in the locked position shown in Fig. 7 when the shutters are fully closed.

It will be noticed that when the levers 6 are in the locked position the cranks 8 of shaft 7 are all at or past the upper center, so that there is no tendency to turn outwardly and dump a load, since very little strain is imposed to twist the shaft or disengage levers 9 .from the pins 9.

I claim as my invention- 1.. In a dumping apparatus for vehicles, a receptacle for materials to be dumped having a bottom consisting in part of shutters each pivotally connected to the receptacle at the ends aside of the center of width of the shutters and notched from the outer edge to a point substantially in a line with the pivotal points at the ends, and means connected with the shutters through which their position relative to the receptacle is controlled.

2. In a dumping apparatus for vehicles, a receptacle for materials to be dumped having a bottom consisting of two shutters each pivotally connected to the receptacle at the ends aside of the center of width of the shutters, and means through which their relative position is controlled consisting of revoluble shafts mounted at the sides of the receptacle, and whichare bent to form double cranks, connecting-rods between the cranks and the shutters,and hand-levers connected with the shafts, for the purpose as shown and described.

3. In ad umping apparatus for vehicles, a receptacle for materials to be'dumped having a bottom comprising two shutters each pivotally connected tothe receptacle at the ends aside of the center of width of the shutters, a central support secured to the receptacle at the ends and between the shutters in close proximity to the latter in the closed position, strips secured to the inside surface of the receptacle in position to overlap the edges of the shutters when in -their closed position, and means connected with the sh utters for controlling and forholding the shutters in the closed position, substantially as described.

1. In a dumping apparatus for vehicles, a receptacle for materials to be dumped having each side recessed longitudinally and transversely, two pivoted shutters forthe bottom of the receptacle, a double-crank rod mounted in e'ach longitudinal recess in the sides, the cranks of which fit in the transverse recesses, means for rotating said rods, and means for connecting the cranks with the outer edges of the shutters.

5. In adumpingapparatus for vehicles, a receptacle for materials to be dumped having a bottom comprising two pivoted shutters, a double-crank rod mounted on each side of the receptacle, the forward end of which is provided with a handle, a stop for each handle, and rods for connecting the cranks with the outer edges of the shutters, said rods being of such a length that when the cranks are in a raised position, each rod will extend substantially across the aXis of the crank-rod-and automatically lock the shutters in a closed position.

In witness whereof I have hereunto set my hand, this 28th day of May, 1904, in the presence of two subscribing witnesses.
