SPECIFICATION forming part of Letters Patent No. 499,830, dated June 20, 1893.

Application filed February 18, 1893. Serial No. 462,850. (No model.)

- improvement in hoisting coal wagons that are employed for the delivery of coal to consumers, and for the dumping thereof at the point of storage without the usual shoveling of the coal into baskets and other receptacles to be carried from the point of dump to storage.

To this end the invention primarily contemplates an improved unloading wagon, which, while specially adapted for the delivery of coal in small quantities, at the same time can also be used for other self-dumping and hoisting purposes.

With these and many other objects in view which will readily appear as the nature of the invention is better understoodthe same consists in the novel construction, combination and arrangement of parts, hereinafter more fully described, illustrated and claimed.

In the accompanying drawings:Figure 1 is a perspective view of a hoisting coal Wagon, the body being hoisted to a, dumping position. Fig. 2 is a central vertical longitudinal sectional view of the wagon, showing the chute gate open in a position to discharge the coal to either side of the wagon. Fig. 3 is a horizontal sectional view on the line osm of Fig. 2. Fig. 4 is an enlarged detail view showing one of the segment guidesl Fig. 5 is a detail in perspective of the bottom of the wagon body showing the lifting arms bearing there- Fig. 6 is a detail plan view of the chute end of the wagon body showing the chute gate open and the extensible chute disposed at an angle to the wagon body to discharge to one side of the same. I

Referring to the accompanying drawings, A represents the bed or truck frame of the ordinary construction, and supported on the front and rear wheels B, in the usual manner.

Secured to opposite rear ends of the truck frame A, are the opposite vertical guide bars or standards O,which are securely braced from their upper ends to the opposite sides of the truck frame by means of the brace rods 0. The said opposite rear guide standards G,-receive the opposite guide clips 0, secured to opposite sides of the vertically movable tilt.-v ing wagon body D, and at the rear dumping end thereof. The said wagonv body D, is of the ordinary construction and is provided with a sliding end gate d, inclosing'the rear discharge opening, from which leads the short fixed chute d, which forms a contracted outlet or discharge for the material within the wagon, and said wagon body may be partitioned off so as to accommodate different quantities of coal to be separately delivered as will be readily understood. The said movable wagon body D, has secured to opposite bottom edges thereof the longitudinal metallic roller guide plates E, on which move the ant-i-friction-rollers F, at the moving extremi ties of the opposite pairs of crossing front and rear lifting arms G and G, respectively.

The front pair of lifting arms G, are lifted independently of the arms G, so as to provide for lifting the front end of the wagon body before and higher than the rear end thereof, and said front pair of lifting arms are pivotally attached at one end as at g, to opposite sides of the truck or running-gear frame A, near its rear end, while the other shorter rear lifting arms are pivotally attached at g, to opposite sides of the running gear frame, near the front end thereof. \Vhen the movable wagon body is loaded and rests flat on the running gear or truck frame, the opposite lifting arms fold down within said truck frame as can be clearly seen in the drawings.

The wagon body D, is hoisted into a tilting position by means of the opposite toothed segments or segment-bars II. The opposite toothed segment bars H, are provided at their upper ends with the notches h, embracing the longer front end lifting arms G, and at the bases of which are arranged the anti-friction rollers h, contacting with said lifting arms so that, as the Wagon body rises, the said lifting arms are free to slide through the upper notched ends of the lifting segments. The said lifting segment bars 11, are further provided at a suitable point intermediate of their ends with the laterally extending lifting pins J, which, after the front end of the wagon body has been lifted a certain distance, are designed to come in contact with the under edges of the rear end-lifting arms so-as to carry up the rear end of the wagon body, as will be easily understood. The opposite toothed lifting segments l-I, work within the curved guide pockets K, of the guide plates 70, secured to oppositeinner sides of the running gear or truck frame A,intermediate of its ends. The curved guide pockets K, correspond to the curvature of the lifting segments and carry therein the combined guide and anti-friction rollers L, over which the smooth edges of said segments slide, as the same are moved up and down. The segments 1-1, are held into the guide pockets K, and are lifted up and down by means of the lifting pinions M, mounted on opposite ends of the transverse lifting shaft m,'journaled in opposite sides of the frame A. The transverse lifting shaft m, also carries the cog-wheel m", which meshes with an adjacent pinion N, on one end of the stub shaft n, journaled at one side of the frame A, and carrying at its outer end the cog-wheel n. The cogwheel 01., is turned by the adjacent driving pinion O, mounted on a crank handle shaft 0, having an outer squared end adapted to detachably receive the operating crank handle employed for operating the wagon. A gravity check pawl P, is pivoted to a suitable point of attachment adjacent to the cogwheel n, and is designed to hold the hoisted load at any desired point, while adjacent to the driving pinion O, is pivoted a pawl brake lever Q,'under the control of the operator so as to ease the drop of the wagon body onto the truck or running gear frame. Now it will be readily apparent that when it is desired to hoist the Wagon body, by starting the train of gearing described from the crank handle, the opposite lifting segments H, are forced up and out of their guides, and therefore lift the lifting arms G, and the front end of the wagon body. If it is desired to increase the tilt of the body and also lift the rear end thereof, the gearing is merely kept in motion so that the lifting pins of the segments come under the rear end lifting arms and therefore also carry up the rear end of the wagon body to the desired elevation as is clearly seen in Fig. 1 of the drawings. After the wagon body has been tilted to the desired elevation, it is necessary to provide means for conveying the coal or other material theresliding extensible chute T, is of the ordinary sectional construction, and which, when extended from under the wagon body, is designed to form a continuation from thefixed chute d, at the rear discharging end of the body, and said extensible chute can be turned, when extended, at an angle to the rear end of the body, and still deliver the material so that the wagon can be driven alongside of the pavement without the usual backing in.

In order to render the chute T, available for discharging to either side of the wagon body as clearly shown in detail Fig. 6 of the drawings, the short fixed discharge chute d, is provided in the bottom thereof with a bottom discharge opening X, which is designed to be covered and uncovered by the gate Y, hinged at y, to one edge of said opening. When discharging straight to the rear of the wagon body the gate Y is closed as shown in Fig. 2, but to discharge to either side of the wagon body the same will be opened, and the chute T, turned around at an angle to the wagon body on its swiveled eye 3, so that the discharging coal will drop through the opening X, onto the chute T, and thereby be discharged to either side of the wagon body without clogging. After the hoisted wagon body is lowered onto the running gear or truck frame,'the said chute is slid back intov position under the body and is supported at its outer end by means of the suppo'rtinglink if, placed into engagement with the hook-end t, of the slide rod R.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described hoisting coal wagon will be readily understood, and it will be noted that changes in the form, proportion and the minor details of construction as embraced within the scope of the appended claims, may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is- I 1.
