DUMPlNG-VEHICLE.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed January 24, 1906. Serial No. 297,660.

To all whom it may concern:

Be it known that I, EDWIN I. NOTTING- HAM, a resident of Washington, District of Columbia, have invented certain new and useful Improvements in Dumping-Vehicles and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in dumping-vehicles, an object of the invention being to provide a vehicle-body comprising two independent sections co6perating when closed to form a single receptacle, but having individual supporting mechanism which permits the sections to be drawn apart to dump or move together to close the body.

A further object is to provide a dumpingvehicle with a hopper-shaped body comprising two half sections independently supported and the supporting mechanisms constructed to be moved relative to each other to separate the body-sections or move them together.

A further object is to provide a vehicle of this character with improved brake mechanism which may be'operated to control the momentum of the vehicle and which is automatically applied when the body-sections are separated or moved together to hold one section against movement during such operation.

With these and other objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation with one wheel removed, illustrating my improved vehicle in closed position. Fig. 2 is a similar view showing the vehicle open for dumping. Fig. 3 is a view in vertical cross-section. Fig. 4 is a view in horizontal section. Fig. 5 is a view showing a train of my vehicles. Fig. 6 is a similar view showing the vehicles in the act of dumping and leveling. Fig. 7 is a view showing my improvements as applied to a wagon, and Fig. 8 is a view showing my improvements applied to a railroad-car.

The body of my vehicle, which is composed of sheet metal and of hopper shape, comprises two half- sections 1 and 2, each having a scraper or leveler 3 at its lower end. T o opposite sides of bodysection 1 box castings or guides 4 are securely fastened in horizontal position and encompass the parallel side channel-bars 5 of a rectangular frame 6, and to which latter thebody-section 2 is securely riveted and strengthened by a crossbar 7 and brace-rods 8, and this body-section 2 is preferably provided at its sides with plates 9, telescoping in body-section 1 and serving as side closures for the body when the sections are separated, to prevent the load falling out at the sides.

Axle-stubs 10 are secured to the box castings or guides 4 and mounted in the hubs 11 of wide-rimmed wheels 12, and caster-wheels 13 are located at the forward corners of frame 6 to prevent tilting of the body and maintain frame-6 always in a horizontal position. Owing to the half-hopper shape of body-section 1, the box castings or guides 4 will project rearward beyond the inclined rear wall of said body-section, and triangular-shaped castings 14 are secured to the rearwardlyprojecting portions of castings 4 and also to the body-section 1, serving to brace and strengthen the latter. In these castings 14 pockets 15 are provided for sliding catches 16, forced outward by coiled springs 17 behind them and connected by chains 18 with a T-lever 19, pivoted to body-section 1. When the body-sections are together, the

catches 16 project into openings 20in side bars 5 of frame 6 and lock the body-sections together, permitting the vehicle to be moved from place to place without separating the body-sections.

To unlock the frame 6 from castings 4, or, in other words, to unlock the'body- sections 1 and 2, supported by the castings 4 and frame 6, the T-lever 19 is swung to either side to draw inward the catches 16, and a chain 21, which is secured between its ends to the upper end of lever 19, may be pulled to accomplish this purpose and may be caught over lugs or pins 22 to hold the catches withdrawn and the vehicle ready to dum Brake-shoes 23 are pivotally secure to the forward ends of castings 4 in position to engage the hubs 11 of wheels 12, and upright brake-arms 24 are secured to the brakeshoes and provided at their lower ends with forwardly-projecting curved or cam extension-bars 25, to be engaged by lugs 26 on body-section 2. The arms 24 and cam extension-bars are preferably made of a single bar of spring metal bent into the shape shown, and this brake-arm 24 may. be swung to apply the brake during transit of the velncles and 1s automatically applied during the separation of the body-section's, as will now cam extension-bars to'press brake-shoes a 23 against the hubs 11 of wheels 12, and

thereby hold the body-section 1 stationary while body-section 2 is pulled away. movement of frame 6 and body-section 2 continues until lugs 26 reach the ends of the cam portions of bars 25, when pressure of brake-shoes 23 will be relieved and the rear cross-bar of frame 6 will have engaged the rear'ends of'castings 4 to limit the separation of the body-sections. As the body-sections areseparated the contents of the body will fall through the open bottom thus made, and when the sections have separated to their fullest extent the vehicle will be in to move forward as the brakes are released, and the rear scraper or leveler 3 will level the pile as the vehicle continues to move forward and dump; When the vehicle has been emptied, the draft-animal or engine will be backed, or draft is applied to the rear end of frame 6, and as the frame 6 begins to slide rearward through castings 4 the lugs 26 will engage cams 25 to apply the brakes and hold the body-section 1 against movement until the sections are together, when the brakes will be released andcatches 1 6 will spring into locked position, and the vehicle is ready to be drawn away for another load.

In Figs. 5 and 6 I have illustrated anumber of my improved vehicles coupled together and operating as a train. A train of such vehicles can be easily drawn by a traction-engine, which latter can be shifted from one end of the train to the other to close the vehicles and draw the train back for another load without turning the train around, which is especially desirable in working on narrow roads.

In Fig. 7 my invention is illustrated ap plied to an ordinary wagon. In this form of my invention, I preferably provide the bar 26 with. two cams and the side bars of frame 6 with two openings 20 for the catches 16, thus permitting the body-sections to be opened half-way or entirely, at the will of the operator.

In Fig. 8 my improvements are illustrated as applied to a railroad-car.

A great many other slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I would have This it understood that I do not restrict myself to the precise details set forth, but consider myself at liberty to makesuch slight changes and alterations as fairly fall within the spirit and scope of my invention.
