DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 258,357, dated May 23, 1882.

Application filed January 12. 1 882. (No model.)

vented a new and useful Improved Dumping- Wagon, of which the following is a full, clear, and exact description. I r

The object of our invention is to facilitafe dumping the contents of a wagon or cart.

The invention consists in adumping-wagon constructed with two adjustable circular racks at the rear end of the box-supporting frame and a circular rack with an extensible arm at the front of this frame, and with suitable gear- :5 wheels, sprocket-wheels, and a driving-chain for operating these racks, whereby the box may be raised and inclined by the front and rear racks; or the rear racks may be disengaged, so that the front end of the box will be raised only, as will be fully described and set forth hereinafter.

. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal elevation of our improved dumping-wagon, parts being broken out. Fig. 2 is a plan view of the supportingframe, the wagon-box being removed.

The wagon-box A is constructed with a false bottom inclined from the front toward the rear, and at its rear end the box is provided with an opening and a spout, B, the opening being provided with a suitable door or gate 5 for closing it. The box A rests on a baseframe, 0, which is supported by the axles and wheels in the ordinary manner. In the rear end of the base-frame G a transverse shaft, D, is journaled, and each end of this shaft,

0 projecting from the sides of the frame 0, is

provided with an eccentric bushing, E, on each of which a large quadrant-shaped or circular rack, F, is loosely mounted in such a manner that this rack extends toward the front of the The upper arm of each rack-frameFis provided at the free end with a short longitudinal slot, at, through which a pintle or stud, 12, passes into the sideof the box A, as shown in Fig. 1. The quadrant or circular racks F engage with pinions G, mounted on the projecting ends of a transverse shaft, H, journaled :the wagon-box A, as shown in Fig. 1.

in the frame 0. On this shaft a cog-wheel, I, is mounted, within theframeO,and engageswith a pinion, l, on ajournaled shaft, J, on which is mounted a cog-wheel, J, engaging with a pinion, K, on a journaled shaft, L, provided atits end projecting from the side of the frame (3 with a ratchet-wheel, L, and a crank, M, on which ratchetwheel L a pawl, M, rests. The shafts J and L arejournaled in one of the outer longitudinal bars, 0, and in one of two longitudinal intermediate bars, 0 of the frame G, .as shown in Fig. 2. A quadrant rack, N,

is loosely mounted between the middle bars,

0 on a transverse shaft, 0, of the frame 0. The upperarm of the quadrant or circular rack N is provided with sliding arms P, which can be adjusted and locked to project a greater or less distance from the outer end of the upper arm of the'quadrant or circular rackNbymeans of pintles or bolts (1, or any other suitable or equivalent device. In the outer ends of these arms P a wheel or pulley, Q, is journaled, which is adapted to slide in a longitudinal groove, R, in the front part of the bottoni of he quadrant-rack N engages with a pinion, S, on ajournaled shaft, T, near the front end of the frame O. Sprocket-wheelsUandVare mounted on the shafts H and T, respectively, and a driving-chain, W, of any suitable construction, passes over these wheels U and V, as shown.

The operation is as follows: If the contents of the wagon-for instance, coals- 4s to pass from the wagon through a cellar -window or other opening into the cellar, a chute must be used, down which the coals can slide from the wagon to this opening or cellar-window. The crank M is turned as indicated bythe arrow a,cai1sing the quadrant or circular racks F and N to swing as indicated by their arrows, as the two shafts H and T, carrying the pinions G and S, are connected by the chain W. The upper arm of the front quadrant or circular rack, N, is'lengthened more or less by means of the adjustable arms I, and the front end of the box A will be raised accordingly higher than the rear end. The entire box is also moved to project from the rear end of the frame 0 a distance equal to the radius of the quadrants or circular racks F. It is not necessary that the upper arm of the front quadrant or circular rack, N, be lengthened; but we prefer to do so, as the front end of thebox A will be raised so much higher; but in place of providing the rack N with the adjustable sliding arms Pthe rack can be made larger than the rear racks, F, and a correspondingly larger pinion, S, must be provided. When the box is thus raised, as shown in dotted lines in Fig. 1, the chute is placed under the spout B and the gate or door in the rear end of the box A is opened. The coals or other materials will slide down this chute into the cellar. If the coals are to be dumped upon the sidewalk or upon the ground, the shaft D is turned about a halfrevolution by means of a wrench or anysuitable key. The eccentric bushings E will move the racks F slightly toward the rear end ofthe frame 0, (the slots at permitting of thi's 'movementfl and these racks F will thus be disengaged from the pinionsG. If the crank Mism-owturned, the'front rack, N, only will be raised, as the racks F are not-engaged with thepinion's G, and the front end of the box only will be raised, and will only draw the racks F upward slightly.

lf the racks F and N are used to dump the box A, the rear end of the same can be projected some distance beyond the curb-stone, so that none of the contents of the Wagon will fall into the gutter in case the chute is not used- Having thus described our invention, we claim as new and desire to secure by Letters Pate'nt- 1 In a dumping-wagon, the combination, with the supporting-i'rame C and the box A, of thequadrants or circular racks F at the rear end-of the wagon and the quadrant or circular rack N at'the front end of the wagon, and of gear-wheels for operating these racks, substantially as herein shown and described, and for the purpose set forth.

2. In a dumping-wagon, the combination,

,with thesupporting-frame G and the box A,

of, the rearquadrants or circular racks, F, the

, front quadrant or circular rack, N, gear-wheels,

sprocket-wheels U V, and the chain W, for operating the frontand rear racks simultaneous- 1y, substantiallyas herein shown and described, and for-the purpose set forth.

3. In a dumping-wagon, the combination, with thesupporting-frame U and the box A,

of the shaft D, the rear quadrants or circular racks, F, the shaft H, the pinions G, the front quadrant or circular rack, N, the shaft T, the pinion S, the sprocket-wheels U and V, the chain W, and of gear-wheels for operating the racks, substantially as herein shown and described, and for the purpose set forth.

4. In a dumping-wagon, the combination, with the supporting-frame and the box, of circular or quadrant racks at the rear end of the wagon, a circular or. quadrant rack at the front end of the wagon, the front rack being provided with an arm adj ustably secured thereto, and of gear-wheels for operating the racks, substantially as herein shown and described, and for the purpose set forth.

5. In a dumping-wagon, the combination, with the supporting-frame O and the box A, of the rear circular or'quadrant racks, F, the front rack, N, provided with sliding arms I, having a pulley, Q, at the outer ends, the

groove R in the bottom of the'box, at the front end of the same, and of gear-wheels for operatingthe racks, substantially as herein shown and described, and for the purpose set forth.

6. In a dumping-wagon, the shaft D, provided with the eccentric bushings E, in combination with the body A, the frame 0, the quadrant-rack F, and mechanism for operating thesame, substantially as shown and described, whereby the said rack is adapted to be disengaged from the operating. mechanism, as and for the purpose set forth.

7. In a dumping-wagon, the combination, with the supp/orting-frame G and the box A, of the front circular or quadrant rack, N, the shaft D, provided with eccentric bushings E, the circularor quadrant racks F, loosely mounted on these eccentric bushings E, which racks are provided at the upper ends with slots at, the pintles b, passing through the slots ainto the box A, and of gear-wheels foroperating these racks, substantially as herein shown and described, and for the purpose of disengaging the rear racks, F, from their pinions, so that the box will be raised by the front rack only,

as set forth.
