DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 628,978, dated July 18, 1899. Application filed November 25, 1898. Serial No- 697,3l7. (No model.)

To all whom it mew concern:

Be it known that I, LESTER A. BURNHAM, a citizen of the United States, residing at O0- l'umbus, in the county of Franklin and State of Ohio, have invented a certain new and use ful Improvement in Dumping-Wagons, of which the following is a specification.

My invention relates to the improvement of dumping-wagons; and the objects of my invention are to provide a Wagon of this class of improved construction and arrangement of parts; to provide separated beds, so supported and operated as to admit of their being dumped and their contents discharged simultaneously; to provide improved means for operating the end-gates of the bed-sections; to so construct my improved dumpingbeds as to admit of their employment on ordinary wagon running-gears, and to produce other improvements the details of construc tion of which will be more fully pointed out hereinafter. 7 These objects I accomplish in the manner illustrated in the accompanying drawings, in which Figure l is a side elevation of myimproved dumping-wagon,showing for the sake of clearness portions of the Wheels broken away and showing the bed-sections in their horizontal or load-carrying positions. Fig. 2 is a side elevation showing the bedseotions in the dumping position and a portion of the side framework shown broken away and the wagon-wheels omitted; and Fig. 3 is a plan view of my improved wagon, showing the beds in the dumping or dumped position indicated in Fig. 2.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I employ a suitable or ordinary form of wagon runninggear, of which 1 represent the wheels 5 2, the axles; 3 and 4, the front and rear truck-bolsters, and 5 the reach or truck coupling-pole, all of the latter being of the usual or any ordinary construction. I

6 represents a bed-retaining frame, which consists of the parallel side frame-pieoesi, the under sides of which are connected at desirable intervals by transverse frame-bars 8. The bed-retaining frame thus formed is adapted, as indicated in the drawings, to extend between and rest upon the front and rear bolsters, in which position it is prevented from lateral movement by the usual bolster end standards 9. Near the forward portion of the frame 6 I support, as indicated, a forward or front bed-section 9, the under side of the latter being fulcrumed, as indicated at 10, to the under side framework of the bed-frame 6, said fulcrum-point being, as indicated in front of the center ofthe length of said forward bedsection. The bed-section 9 has its rear end portion open and adapted to be closed in the manner hereinafter described by an end-gate. The rear portion of the floor of the front bedsection is, as indicated more clearly in Fig. 3 of the drawings, provided with a central recess, preferably of the tapering form indicated at 11. 12 represents the front bed-section end-gate, the latter being provided at each end with oppositely-located ratchet trunnions or pins 13, which bear upon the upper sides of the side frame-pieces 7. The inner side and lower portion of the end-gate 12 is provided with a forwardly-prejecting floor section or tongue 14, which is of such form, as indicated in Fig. 3, as to cover the floorrecess 11 of the front bed when the end-gate 12 abuts against the rear end of said bedsection. As indicated in Fig. 2 of the drawings, I provide the lower portion of the endgate 12, near each end thereof, with a forwardly-projecting catch-finger 15, the latter being adapted to engage the under side of the rear end portion of the bed 9 when the endgate is in the closed position.

16 represent bed coupling bars, one of which is employed on each side of the wagon, the forward ends of said coupling-bars loosely engaging the projecting end-gate pins 13, and the rear and lower portions of said bars being provided with longitudinally-slotted openings, as indicated at 17, said slots engaging laterally-projectingpins 18 on the sides of a rear bed-section 19, which has its forward portion when in a horizontal position bearing between the rear portions of the frame side pieces 7 and which has its forward closed end adjacent to the rearend of the front bed-section. The rear bed-section 19is, as indicated at 20, fulcrumed to the rear end portion of the bed-retaining frame 6, the transverse fulcrum-rod which I employ for this purpose preferably being provided with upwardly-extending end portions 21, which are secured to opposite sides of the bed 19.

In constructing the rear bed-section I form the rear end thereof open and provide a swinging end-gate 22, adapted to close the same in the manner hereinafter described. In hinging the rear end-gate 22 to the bed 19 I provide a hinge-yoke 23, from the rear and transverse portion of which is suspended said swinging end-gate. The side arms of the hinge-yoke 23 bear upon shoulders or looks 24, secured to the sides of the rear portion of the bed and adjacent to the top thereof, while the extremities of said yoke side arms are fulcrumed to said bed, as indicated at 2st.

To the lower portions of the bed 19, adjacent to the rear end thereof, I fulcrum, as indicated at 26, the ends of an end-gate latchyoke 27, said fulcrumed end portions being provided with catch hook extensions 27 which are adapted to engage the lower sides and end portions of the rear end-gate and retain the latter in the closed position indicated in Fig. 1 of the drawings. The rearwardlyextending or loop end of the yoke 27 is adapted to contact with the beveled face of a rearwardly-projecting contact-block 28, which is latter having fulcrumed thereto at a point in front of its fulcrum-point the forward end of a'rearwardly-extending dumping bar or rod 32, the latter having its rear end fulcrumed to the rear bed-section 19. It is obvious that when the beds are loaded and in the horizontal position upon the truck-frame the lever 31 will be turned downward to the position indicated in Fig. 1, thus bringing its point of connection with the bar 32 below the fulcrumpoint of said lever and serving to retain the rear bed-section in the desirable horizontal position. The parts being in this position it is also obvious that the laterally-projecting pins 18 of the rear bed-section will be locked in the forward ends of the slots 17 of the bars 16.

In order to illustrate the operation of my improved dumping-wagon, we will assume that the bed-sections thereof have been previously loaded with gravel, broken stone, or any other material which it is desired to convey and dump. When the dumping-point is reached, the raising of the lever 31 and consequent rear movement of the bar 32 must result, as will readily be seen, in a rear tipping movement of the rear bed. This rear bed having thus been tipped until the side pins 18 are in contact with the outer ends of the slotted openings 17 it will be observed that the resultant pull on the bars' 16 will cause the end-gate of the forward end section to travel outward and cause a withdrawal of the supporting-pins 15 from \the bed, allowing the latter to tip through the weight of the material therein to the position indicated in Fig. 2 of the drawings. Owing to the formation of the fioor-recess 11 in said front bed= section it will be seen that the rear portion of said front bed-section will straddle the reach 5, thus insuring a desirable drop or incline of the rear end of the bed. The tipping of the rear bed-section, which is caused by the movement of the bar 32, results through the contact of the latch-yoke 27 with the reartruck projection 28 in a sufficiently downward movement of the latch extension 27 to cause a disengagement of the latter with the rear endgate and admit of said endgate swinging open to the position indicated in Fig. 2. Owing to the fact that the pivotpoints of the hinge-yoke of said rear end-gate are located at a distance from theend of the bed it will readily be seen that when said end-gate comes into contact with the ground or material dumped the same may be raised until its upper portion is above the bed, thus preventing the imparting of unnecessary pres sure or weight to said end-gate.

In the manner above described it will be seen that simple, reliable, and effective means are provided for tipping and discharging the contents of the bed-sections herein shown simultaneously, or substantially so, and it will also be observed that the contents of the rear bed-section are discharged without contact with the wagon gear orframework, while the contents of the forward section are discharged at such point as to prevent any injury to either of the trucks or other framework.

It is evident that the processof returning the bed-sections to their horizontal or normal positions must consist in forcing the handlever 31 downward to the position indicated in Fig. 1 of the drawings, this movement resulting not only in said beds assumingtheir normal positions, but in the moving of the end-gate 12 forward against the rear end of .in said bed-bottom.

It will be observed that the parts of my improved dumping-wagon are simple of construction and that the beds and bed-retaining frame, together with the operating mechanism, may be readily applied to an ordinary wagon running-gear without change to the latter.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is v 1. In a dumping-wagon, the combination with a wagon running-gear, of a bed-retaining frame mounted thereon, front and'rear bed-sections supported and fulcrumed in said retaining-frame, an end-gate for said front section having a sliding support on said retaining-frame, bars 16 jointedly connecting said front-bed end-gate with said rear bed and a lever-bar j ointedly connected with said rear bed and means for moving said leverbar rearward, substantially as and for the pn rpose specified.

2. In a dumping-Wagon, the combination with a Wagon running-gear, of a bed-retain- 3. In a dumping-Wagon, the combination with the running-gear having a projection 28 on its rear truck, a bed-retaining frame supported thereon, front and rear bed-sections independently fulcrumed to said frame, an end-gate hinged to the rear end of said rear bed, and a spring-actuated latch-yoke fulcrumed to said rear bed, said yoke having a catch extension adapted to engage said endgate and retain the same in a closed position and the rear portion of said yoke having contact With said rear-truck projection, substantially as and for the purpose specified.

LESTER A. BURNHAM.
