NITED STATES JOHN BULLOCK, OF WILMINGTON, DELAWARE.

DUMPING-WAGON.

SPECIFICATION forming part Of Letters Patent No. 635,420, dated October 24, 1899.

Application filed April 7, 1899. Serial No. 712.135. (N0 model.)

To all whom it may concern.-

Be it known that I, JOHN BULLOCK, a citizen of the United States, residing at Wilmington, county of New Castle, and State of Delaware, have invented a certain new and useful Improvement in Dumping-VVagons, of which the following is a specification.

My invention relates to a new and useful improvement in dumping-wagons, and especially to that class of wagons which are intended for the delivery of coal, and has for.

its object to generally improve upon the construction of such wagons, removing all obstructions from the interior of the body thereof, so that the coal may freely flow therefrom, and to increase the height to which the body may be raised in awagon of given dimensions, and also to increase the distance to which the rear end of the body may be carried relative to the running-gear, thereby greatly facilitating the delivery of the coal.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of a wagon made in accordance with my improvement,the body beingin its normally-lowered position; Fig. 2, a similar View showing the body raised to its highest point; Fig. 3,a side elevation showing the body tipped at the greatest angle after being raised; Fig. 4, a central longitudinal section of the wagon, showing the relative position of the operating mechanism when the body is lowered; Fig. 5, a bottom plan of the wagon; Fig. 6, a rear end view thereof, and Fig. '7 a section on the line x as of Fig. 1.

In carrying out my invention as here embodied, A represents the frame of the wagon, which is suitably mounted upon the wheels B and O, and from the rear portion of this frame dependthe supports D, having pivoted thereto at E the lifting-bars F, there being one upon each side of the wagon. The upper ends of these bars are pivoted at G to theside of the rails 11, and at these same points are also pivoted the operating-bars I,

the lower ends of which have journaled therein the rolls J, adapted to travel upon the incline tracks K, said tracks being preferably formed of wood and bound with metal. The operating-bars are connected at their lower ends by a cross-piece L,havin g attached thereto the pulleys-M, over which run the chains N.

One end of each of these chains is attached to the side rails of the wagon-frame at 0, their opposite ends being secured to the Windlassshaft P. By this arrangement it will be seen that when the Windlass-shaft is revolved in the proper direction the chains will be coiled thereon, during which operation the operating-bars will be drawn inward, their lower ends traveling up the incline tracks, thus elevatin g the body, as will be readily understood. While the body is being thus elevated, itis prevented from upsetting by the stay-rods Q, the upper ends thereof being pivoted at Rto the front of the body, while their lower ends are pivoted to the clips S. These clips are adapted 'to slide upon the side bars T, in which are formed holes U, in order that the clips may be held in any adjustment upon these side bars by the passage of a suitable pin through a hole in each of the clips and in "one of the holes in its side bar.

further increase the angle of the body until reaching the position shown in Fig. 3, which represents the greatest inclination at which the body may be set, being considerably greater than the angle possible to be attained in wagons of the same dimensions of the usual construction. The Windlass-shaft P is operated through a train of gears consisting of the gear V, secured upon said shaft, meshing with the pinion \V, pivoted upon a stud X, said pinion being formed with or'secured to a gear Y, which latter in turn meshes with the pinion Z. This last-named pinion is secured upon the crank-shaft (1-, adapted to receive a suitable crank 12, by which it may be revolved, and in so doing transmit motion to the Windlass-shaft P to bring about the operations before set forth.

A pawl d, meshing with the teeth of the pinion Z, prevents any retrograde movement of the crank-shaft, so that when the body is being elevated the operation may be suspended at any time without danger of downward movement thereof. hen it is desired to lower the body, the pawl is disengaged from the teeth of the pinion, and to prevent a too rapid rotation of the crank-shaft a brake e, pivoted at f, is forced against the outer portion of the crank-shaft or a disk thereon to retard this rotation.

A suitable bracket g is secured to one of the side rails of the wagon-frame and serves as an outside bearing for the train of gearing, including the crank-shaft.

It is to be noted that by the construction here shown and described no obstruction is placed within the body of the wagon, and therefore the coal will readily flow therefrom without being hindered in its passage to the chute or other point of delivery.

The rear end of the body is provided with an upper end-gate h, which is hinged at 1', so as to be swung downward, and beneath this gate are hinged the two smaller gates j, so as to swing outward. A chain l is secured to the upper end-gate at m and passes through the eyes a, terminating in hooks p, which are adapted to'en gage the edges of the lower bars, so that when these are swung open and thus acted upon their outward movement will be limited, thereby directing the flow of the coal toward the center in passing from the body.

I am aware that wagon-bodies have been mounted so as to be elevated upon operatingbars to which they were pivoted and that stays have been utilized to hold such bodies in position, and I do not broadly lay claim to such a construction; but

WVhat I do claim is 1. A dumping-wagon consisting of a suitable frame mounted upon wheels having supports depending therefrom, supporting-bars pivoted to the last-named members, a body to which said bars are pivoted at the center thereof, operating-bars pivoted to the body at the same point as the last-named bars, rolls journaled in the lower ends of the operatingbars, inclined tracks supported by the frame upon which said rolls are adapted to run, a windlass-shaft, two chains attached thereto, pulleys attached to the operating-bars around which said chains pass, the opposite ends thereof being attached to the Wagon-frame, means for revolving the Windlass-shaft whereby the body may be elevated, stay-rods pivoted to the front of the body, clips to which the lower ends of these rods are also pivoted, side bars upon which the clips are adapted to slide, said side bars and clips having holes therethrough for the passage of pins to hold the stay-rods in adjustment whereby the body may be swung to any desired angle within certain limits, as and for the purpose set forth.

2. In combination, a wagon-frame suitably mounted upon wheels, a body adapted to be supported by said frame, support-bars pivoted to the frame and to the body at its center upon the lower edge thereof, whereby no obstruction is formed within the body, operating-rods pivoted at the same point to the body, their outer ends having rolls journaled therein, inclined tracks upon which said rolls are adapted to run, means for drawing these rolls inward and up said tracks, whereby the body is elevated, a stay-rod so pivoted to the body and frame as to produce a parallel movement with the support-bars, and means for adjusting said rods, as specified. 3. In combination with the body of a wagon of the character described, an end-gate h pivoted to the upper portion of the rear end of the body so as to be swung downward, means for holding it in its closed position, two gates jhinged beneath the first-named gate and adapted to swing horizontally, and a chain secured at its center to the first-named gate and passed through suitable clips terminating in hooks adapted to engage the edges of the said gates j, as and for the purpose set forth.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

JOHN BULLOCK.
