DUMPlNG-WAGON EPECIPICATION forming part of Letters Patent No. 367,103, dated July 26, 1887;

Application filed January 31, i887. Serial No. 226,074. (No model.)

and Lows NAPOLEON BERGERON, citizens of the United States, residing in Stillwater, in the county of Washington and State of Minnesota, have invented certain Improvements in Dumping-YVagons; andwe do hereby declare that the following'is a full andexact description of the same, reference being had to the accompanying drawings, making part of this specification.

Our invention consists incertain improvements in the dumping mechanism of a wagon or cart; in the peculiar means by which the wagon or cart body is held upon the supporting-frame of the running-gear, add in the construction ofthe tracks on the said supportingframe, on which the Wagon or cart body slides in dumping. These improvements will be fullyset forth and defined in the following description and claims. v

In the accompanying drawings, Figure 1 represents a central longitudinal vertical section of a dumpingwagon provided with our improvements; Fig. 2, a top view of the runhing-gear and frame of the wagon, the Wagon body being removed, except the hinged connection thereof with the endless chain by which the said wagon-body is moved backward and forwardin dumping; Fig. 3, a view of the under side of the wagon-body, showing also the endless chains in place in connection therewith; Fig. 4, a rear view of the wagon, the wagon-body being in cross-section in a plane cuttingjust at the rear of the runninggear frame; Fig. 5, a partial vertical section on an enlarged scale of the wagon around the tilting center of the body, showing the body in a tilting position.

Like letters designate corresponding parts in all of the figures.

In the drawings, A represents the .wagonbody 5 B, the frame of the running-gear; O C

, the front wheels, and D D the hind wheels, of

the wagon.

Upon the side timbers, a a, of the supporting-frame B of the wagon two metallic tracks,

' E E, are secured, on which two counter metallic strips, F F, on the bottom of the wagonbody A respectively slide, to take the wear and reduce the friction incident to the backward and forward sliding movements of the wagon-body in dumping. There is nothing special in the construction of these parts, ex-

cept that the steel or iron straps which form the tracks E E are bent around the rear rounded ends, I) b, of the side timbers, a a, of the frame, on which rounded parts of'the tracksthe wagon-body turns and slidesalittle in tilting; and the said track-straps are extended forward under the said side timbers and embrace the ends 0 cof the bolster G,which rests on the hind axle, H, of the wagomand thence forward and upward to the said side timbers, to which they are respectively bolted at d. These track-strapsthus fulfill the ad-' ditional purpose of braces for uniting the bolster to the frame and rendering its connection strong and firm.

For operating the wagon-body, in dumping the same, and returningit to position after its contents shall have been discharged, we employ one or more, preferably two, endless chains,l I, in connection with sprocketwheels or simple wheels J J on a shaft, K, mounted in the frame B in a proper position forward of the middle line of the wagon-body when in preferably the forward shaft, K, in one or the other direction. This may be effected by eX- tending one end of the shaft beyond the frame and attaching a winch or crank wheel thereto. But in order to gain leverage, so as to move the wagon-body more easily, it is best to gear the shaft 11"] to another parallel shaft, N, mounted in the frame, by the proper gearwheels, f g, to give the desired relative speeds to the two shafts, and attaching a winch or crank,0,to the shaft N, as shown in the drawings. The endless chains 1 I are connected with the wagon-body A for imparting the movement thereto by means of shackle-links or swinging hingesl P,piv0ted to a cross-bar,

11, under the floor of the wagon-body, and also pivoted, respectively, to links of the endless chains, substantially as shownin the drawings. Thus the shackle-links adapt themselves to the proper inclined positions in whichever direction the chains are moving, so as to draw on the wagonbody without strain in either direction. A feature of value in the construction and arrangement of this operating mechanism is that the chains and sprocket-wheels are arranged near the middle of the runninggear frame, one on one side and the other on the other side of the center, whereby the weight thereof is kept from leaning, to either side,but perfectly balanced or equalized on both sides of the wagon.

For holding the wagon-body on thesupporting-frame at all times, whether thebody is up right or tilted, and yet not to interfere with the sliding and tilting movements of the body in dumping, we employ two guide-arms or dogs,It It, pivoted upon the rearsproclcetwheel shaft, M, and respectively reaching up and holding overthe upper sides of longitudinal bars, j j, under the bottom of the wagonbody, near the sides thereof, The outwardlyprqleeting flanges of the guidearms are of considerable length, as shown, to rest on the said longitudinal bars of the wagonbody, and thus hold securely upon the said bars without much friction; and the arms turning on the sprocket-shaft M, which is concentric with the tilting motion of the wagon-body, hold the said wagon-body on the frame as well when it is tilted as when itisupright. Suitable washers, It: 1;, if necessary, are placed on the shaft M between the arms R- R and sprocket-wheels L L, to keep them separated and retain the arms in proper position.

A suitable hook, Z, attached to the front part of the frame B under the drivers seat S, hooking into an eye, m, on the front end of the wagon-liiody, serves to hold the said wagonbody securely in place. Any equivalent means may be employed.

\Ve claim as our invention 1. The tracks E E, in con'tbiuation with the side timbers, a a, having rounded rear ends, and the bolster G, the said tracks being bent around the rounded rear ends of the said tim bers and serving as braces for the bolster, snhsiantially as herein set forth.

2. The combination, with the tiltingwagonbody A and rnnning gear frame 13, of the endless chains I I, coupled to thewagon-body,

s n'ocket wheels J J and L L, and shafts K M, substantially as and for the purpose herein specified.

3. The combination of the wagon-body A, endless chains I I, and swinging hinges l P, pivoted to the said wagon-body and chains, snbstantialiy as and for the purpose herein set forth.

4. The pivoted guide'arms R It, in combination with the wagon body A andsproeketwheel shaft M of the frame B, substan tially as and for the purpose herein set forth.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
