SPECIFICATION forming part of Letters Patent No. 604,789, dated May 31, 1898. Application filed August 16, 1897. Serial No. 648,480. (No model.)

To all whom it may concern:

Be it known that I, OLIVER B. REYNOLDS, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of I\[tSStOhUS6l3l1S,hfLVG invented certain new and useful Improvements in Dumping-lVagons, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to that class of vehicles designed for hauling heavy loads and commonly known as dumping wagons; and my invention consists of the parts and the constructions and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming part of this specification and in which similar letters of reference indicate correspond ing parts in the several views, Figure 1 represents a side elevation of a dumping-wagon embodying my invention and showing by dotted lines the movement of the centrally-fulcrumed tiltable body. Fig. 2 represents the body elevated and pivotally hung at its rear end and showing at the front end the means for elevating said end and swinging the body about its rear fulcrums. Fig. 3 is a detail of the lifting-jack arrangement for elevating the front end of the body. Fig. 4 is a bottom view of a portion of the body, showing the means for locking the body to the side-bars of the frame of the vehicle. Fig. 5 is aside view of Fig. 4. Figs. 6, 7, and 8 illustrate detached views of the adjustable end gate or chute. Figs. 0, 10, 11, 12, 13,14, 15, 16, and 17 are details of construction to be hereinafter referred to.

In constructing my improved wagon I use any appropriate and well-known form of running-gear, comprising front and rear wheels A A, and a frame consisting of longitudinal side-bars B and one or more cross-bars O, said frame being supported upon springs D, as shown in Fig. 1. To the side-bars 15 are bolted or otherwise rigidly secured the vertical hangers or standards E, having open bearings at their upper ends to receive the journals or trnnnions a, projecting from the sides of the wagon-bod y. These trunnions and their hearings or standards are centrally located with respect to the wagon-body, whereby when the body is loaded the weight is equally distributed or balanced, and the body may be tilted about the central axis thus formed with the exercise of a minimum of power. The wagon-body F is otherwise of any usual and appropriate construction, depending on the character of the use to which it is put. It has an end discharge controlled by a vertically-sliding gate or valve 1), and it has an adjustable end chute which will be hereinafter specifically described.

Depending from the rear portion of each of the side-bars B is a curved bracket G, having a series of holes or sockets c, which in connection with certain features to be presently described enable the wagon-body to be tilted and secured at different inclinations.

As it is desirable to prevent the body from movement toward and from the side-bars B of the main frame, I secure to the end of the side-bars the outwardly-projecting studs (Z, Fig. 4, and adapt these for dropping into engagement with slots or open bearings e in castings or brackets secured to the inner sides of a cross-bar f on the under side of the rear portion of the body, as shown in Figs. 1, 4, and 5, these connections being such that when the body is tilted about its central fulcrum or bearing the engagement of the studs and slotted brackets is readily broken, so as not to interfere with the tilting action of said body.

To lock the body to the side-bars, I may use various means; but the preferred one is shown in Fig.4 as consisting of suitable guides or plates g, bolted or secured to the under side of the body, near the rear end thereof, and provided with bolts h, slidable therein and actuated simultaneously by means of rods 2', connecting the inner ends of the bolts with a horizontal hand-lever II, fulcrumed to the body and having the rods '5 connecting with it on opposite sides of and equidistant from its pivot, said lever projecting from the rear of the vehicle, so that it may be readily operated to retract the bolts from their engagement with the stationary side-bars and thereby enable the wagon-body to be readily tilted about its centrally-located side trunnions. This lever II will also be found useful in effecting tho ilting of the body after the bolts are withdrawn, and the outer ends of the bolts are preferably made tapering or wedgeshaped, Fig. 16, so that when forced into the holes or sockets j in the inner faces of the side-bars B they tend to slightly raise the rear end of the body B and thereby remove in the center of the load.

the weight of the load from the central side trunnions and transfer it to two strong bolts at the rear, it being understood that the front portion of the body is supported by the crossbar 0. (Shown in Figs. 1 and 2.)

A plate Z (see Fig. 15) is secured to the rear cross-bar f of the body and has a slot 11, in which the lever H passes, the slot being widened at one end to enable the lever to drop therein and be held against accidental movement. In addition to these features the body is provided with an adjustable chute at its discharge end and in communication with its tail-gate. This chute Iis shown in detail in Figs. 6, 7, and 8, and consists of a threesided body hinged at m to the lower edge of the tail-board and provided with pivoted links a, adapted to hook over and embrace the notched or toothed edges of suitable plates 0, projecting edgewise from the rear of the body. By this arrangement the inclination of the chute may be changed at pleasure. It may be held in a horizontal position when the wagon-body is tilted to enable the contents of the body to be shoveled out of the chute, or it may be still further elevated to entirely shut off the flow of the material.

When in the position shown in Fig. 1 and the.

dotted position of Fig. 6, it serves to direct the flow of the discharging material in the usual manner. In any of its adjustments it is securely held by the links at dropping into engagement with the notched plates 0.

If the wagon-body is centrally suspended and is fully loaded, the weight will be evenly distributed and nicely balanced and the body can be readily tilted; but if the body is loaded with about, say, one-half of its capacity it would be much more easily tilted if its point of suspension was correspondingly lowered on the body, so as to be located approximately Now if the pivots or trunnions have their positions on the body changed the supporting-standards must also be changed to properly receive the trunnions in their newly-adjusted positions, so that the body when in a horizontal position may assume the same position on the main frame or side-bars B. To accomplish these results, I show in Figs. 9 to 14, inclusive, the detailed construction of the standards and their connections. The trunnions are carried by levers J, fulcrumed at one end to the body and having handle-pieces at the opposite ends, said levers having curved extensions or members J from their under sides and movable through guides K. There is also secured on each side of the body a bar or plate L, with spaced lugs or ears at each end, while a companion bar or plate L is pivoted between the lower lugs or ears p and has its inner face recessed or notched at different points. The free end of each of the levers J passes across one of the plates or bars L, and the other plate or bar is latched or closed upon it, so that the lever will rest in one of the recesses or notches, after which the upper end of said bar or plate is secured between the upper lugs or ears p on the bar or plate L by means of a pin q or other fastening. Thus the trunnions a may be raised and lowered in vertical planes by unlatchin g the member L and raising or lowering the lever J, after which the parts are latched and the lever fixedly secured, as before described.

To accommodate the adjustments of the trunnions, I make the hanger or standard also capable of vertical adjustment. This is done by forming the hanger or standard of a fixed and movable member, the fixed member r being slotted or channeled and the movable member r being slidably secured therein and having an open-top bearing for the trunnion a. The movable members are adjusted vertically to correspond with the adjustment of the trunnions, and said members are each fixed in their adjusted positions by means of a clasp or hinged or swinging plate 8, pivotally secured to the stationary member 1" and having a lug on its inner face to enter one of the series of notches or grooves formed in the adjacent face of the movable member 1", said hinged or swinging plate or clasp .9 being in turn secured between lugs 15 on the member 4" by means of a pin or fastening, as shown in Figs. 11 and 12.

The description so far relates entirely to the tilting of the body about a central axis, as this is the easiest method of dumping a loaded wagon, owing to the fact that the weight is equally distributed and balanced; but when such a wagon-body is tilted the rear end lowers in the same proportion as the front end raises. In some instances it is desirable that the rear or discharge end should maintain its height without regard to the elevation of the front end, and I provide for this by the construction shown in Figs. 2, 3, and 4:. The bolts h in this instance serve as fulcrums about which the body tilts, and the positions of these bolts may be changed by making them engage the holes in the brackets, these said bolts being operated by the lever and connections before described as furnishing the means for locking the body to the side-bars B.

The elevation of the front end is accomplished by means of the lifting-jack arrangement shown in Figs. 2 and 3 and consisting of a curved and double-faced ratchet-bar O, hingedly secured to the lower front edge of the body, and a fulcru med lever P and doubleacting pawls Q, whereby the rack-bar and body are raised. To lower the front end of the body from its elevated position, the pawls are thrown out of engagement with the ratchet-faces of the bar, and by pressing on the long arm of a fulcru med lever B the short arm of the lever acts to force the lower free end of the ratchet-bar against the wall of the slotted guide in which said free end moves, thereby controlling the descent of the body.

From this description it will be seen that I am enabled to suspend a load centrally and tilt the body about a central axis. I am also ICC permitted to change the axis of the body with relation to the weight carried, and when circumstances require tilt the body about a rear fulcrum and fix it in any position during the period of dumping.

My wagon is simple in its construction and may be tu rned so that its front gear will stand at right angles to the body. It is easily operated and altogether is very desirable for hauling and discharging coal, gravel, and other materials.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. I11 a dumping-wagon, a tilting body having trunnions about which it tilts and means whereby the trunnions are maintained approximately in the center of gravity of the load.
