DUMPING-WAGON.

SEECXFIGATXGN forming part of Letters Patent No. 691,330, dated January 14, 1902. Application led May 16, 1901. Serial No. 60,473r (No model.)

T0 (all 1071/0771/ it' puny concern:

Be it known that I, DAVID SWATSON, a citi- Zen of the United States, and a resident of Oanastota, in the county of Madison, in the State of New York, have invented vnew and useful Improvements in Dumping-VVagons, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to a wagon which is designed more particularly to be usedin cities for collecting garbage, dac., and it has reference to that class of dumping-Wagons having a covered metallic body which is adapted to be tilted rearwardly to discharge its load.

One of the features of my improved dumping-wagon resides in the novel arrangement and construction of the mechanism employed for tilting the body, which mechanism comprises a suitably-journaled shaft provided with a gear, a system of levers connecting said shaft and body, a worm meshing With said gear, and means for rotating said worm,which means can be easily and conveniently operated by a person riding upon the wagon without dismounting. Y

One of the advantages derived from the tilting mechanism used is that the body is sustained at any angle of inclination, and another advantage is that the said body is securely locked in its normal position, owing to the peculiar disposition of the aforesaid levers when the body is in said position, Wherebythe liability of accidental tilting of the said body is prevented, which accidental tilting might otherwise occur during loading or by reason of a greater part of the load being shifted to the rear end of the body incident to the jar during transportation. In connec- -tion with said tilting mechanism I employ a set of primary pivotal bearings and a set of secondary pivotal bearings for supporting the rear end of the body, said bearings being so disposed as to sustain said body on the primary set during `its initial tilting movement and to. transfer'the support ot' the same to the secondary setduring the remainder of its tilting movement,which latter bearings serve to"-sustain the tilted body at a greater elevatloniabove the hind running-gear and shift the body rearwardly, whereby the material is deposited a greater distance to the rear of the Wagon, which is especially desirable Where the load is required to be deposited onto boats and over embankments in View of the fact that the wagon does not have to be backed up closely to such dangerous places.

Furthermore, the invention consists in the novel construction of the wagon-body, which permits of quick and easy loading and effectually prevents the escape of any odors arisingfrom the material contained therein and also in the novel means for automatically opening the discharge-door during its tilting movement; and the invention consists in the details of construction and combination' of parts of the Wagon, as hereinafter fully described, and illustrated in the accompanying drawings, in Which- Figure Al is a side elevation of a dumping- -wagon embodying my invention, the body being shown in its normal position. Fig. 2 is a vertical longitudinal section of the same with -the carrying-Wheels removed. Fig. 3 is also a vertical longitudinal section of the wagon, showing the body in its tilted position. Fig. 4 is a vertical transverse section on line X X in Fig. 1 viewed toward the rear. Fig. 5 is a horizontal longitudinal section on line Y Y in Fig. 1 with the carrying-Wheels removed. Fig. 6 is an enlarged detail side View of the Worm-gearing which is employed for tilting the body. Fig. 7 'is an enlarged sectional vview of a part of the supporting-frame and the body, illustrating more clearly the aforesaid pivotal bearings. Fig. 8 is a rear View of the parts shown in Fig. 7. Fig. 9 is a longitudinal section on line Z Z in Fig. 7, Fig. 10 is a vertical transverse section on line 1 1 in Fig. 7. Fig'. 11 is a detail plan view of the Wagon-body. Fig. 12 is an enlarged detail view of a portion of one side of the body, illustrating one of the hinged doors and one of the sliding doors which are disposed over the openings through which the body is loaded. Figs. 13 and 14 are longitudinal sections on lines 2 2 and 3 3, respectively, in Fig. 12. Fig. 15 is a side elevation of the Wagon, illustrating a modification of the means for turning the 'worm-gearing.

IOO

Referring to the drawings, A represents the metallic body, which is secured to a frame A',

may also be of any suitable form, butis preferably com posed of two longitudinal side bars a c and a rear transverse bar b, rigidly secured together, which bars a a are L shape in cross-section, as clearly shownl in Figs. 4 and 8, and may be connected in any suitable manner at their forward ends, as by `a board c. (Shown in Fig. 5.)

The frame A', to which the body is secured, is composed, preferably, of longitudinal bars d d and transverse end bars e e, and itis normally seated upon the horizontal portions of the L-shaped bars d a of the frame B, as more clearly illustrated in Fig. 4.

- The rear end portion of the bottom of the body is inclined forward, as indicated at f, thus forming a chute, which causes the material. to be thrown a greater distance from the wagon, and the sides of the body are riveted y to the bottom and have the rear end portions of their top edges inclined rearwardly, as shown at g.- The cover B is rivetcdto said n sides and is formed with a central longitudi- 'the same at the rear end, and the cover is further stiffened by means of a board k, secured to the central longitudinal portion thereof. y

f At the rear end of the body is provided a discharge-openingl, and over said openingis -ay door ym, which is hinged at its upper edge to the central longitudinal portion of the cover, as indicated at n, and normally lies upon the inclined edges of the sides. To said door 1n, adjacent to its hinge, is pivoted an arm o, to which is secured one end of a :rope or chain 1o, which extends lengthwise over the cover B' and through eyes q q, secured thereto, and is fastened at its opposite end to the seatrof the wagon. It will be seen that when the body is tilted rearwardly the rope is made taut, whereby the said door is caused to be opened, as clearly shown in- Fig. 3, andv'hen the body is brought to itsnormal position the door will close automatically by gravity.

One or both of the sides of the lbody may be provided with openings s s, and the in-` clined portions of the cover are each pro- Y vided with openings t t, which openings serve by said doors are adapted to be swung down against the side. The hinged edges of said vto said cover.

doors are formed, preferably, with inwardlyprojecting anges w w, as clearly shown in Fig. 4, to prevent lodging of material upon the bottom edges of the openings s s during the process of loading the wagon.

To retain the doors u u in their closed position, I provide a lock comprising a pair of longitudinal rods a; extending through guidesy y on the door and in opposite directions, whichV rods are pvotally connected at their inner ends to a disk a, pivoted to said door, and engage eyes a' a with their outer ends, said eyes being formed in vertical bars b b', secured to the sides of the body at the ends of the door. The disk is provided with a handle c', by which to turn the same, whereby the rods are made to engage and disengage the aforesaid eyes, and in place ot' said disk a two-armed lever may be substituted.

The openings t tin the cover B' are provided with doors d' d', which slide with their side edges in guide bars or tracks e' e', secured Said latte;` doors are held in their open positions by means of camsff, pivoted to the outer face of the doors and adapted to engage the edges of said guidebars, and said cams are provided with operating-handles g g'.

In order to add greater stiffness to the wagon-body, I secure longitudinal bars g3 g3, L shape in cross-section, to the sides of same, as clearly shown in Figs..1 and 4. Y

71,' denotes a transverse shaft which is journaled in suitable bearings Q1' i', secured to the under side of the supporting-frame B, and to said shaft, as indicated at k3, are rigidly secured one end of a pair of levers j 7", which 'are pivotally connected at their other ends,

respectively, to one end of another pair of levers lo' la at h3, which latter are pivotally connected at i3 to the under side of the frame A', to which the body is secured. To said shaft h at the outer side of one of the longitudinal bars of the supporting-frame is rigidly secured a gear m', which is inclosed by a casing fn', which latter is suitably attached to said frame, and with said gear meshes a Worm o', journaled in a casing p', formed integral with the casing ln. To said worm is rigidly secured an upwardly and forwardly extending shaft or rod q', which is suitably journaled at its forward end, as shown at r', and to said end is secured a hand-wheel s' for turning the shaft.

To the rear end of the frame A is rigidly secured a transverse bar D by means of bolts t' t', and to said vbar is rigidly fastened, by bolts t2 ta pair of depending arms u'u,formed with pivots o' o back of and below the supporting-frame B and with pivotsw w', disposed back of the pivots o' 'v'.

To the under side of the cross-bar b of the supporting-frame B is rigidly secured a pair of brackets a? c2 by means of bolts b2 b2, each of which brackets is composed of a pair of like integral plates disposed side by side and formed with upwardly and rearwardly ex- IOO IIO

tending segmental slots c2 c2, the lower ends of which constitute primary bearings, (indicated at tZ2,)in which the pivots o' v are seated, whereby the rear end of the body is sustained during its initial rearwardly-tilting movement. Back of and below` said primary bearings the brackets are formed with secondary bearings e2 e2, in which the pivots w' w' are adapted to be seated, whereby the primary bearings are relieved and the rear end of the body `thereby sustained on said secondary bearings during the remainder of its tilting movement. Said sets of bearings being disposed one back of the other cause the body to swing in two arcs described from separated centers, and thus the body is shifted rearwardly simultaneously with its tilting, and both sets being located in front of the rear axle maintain the weight of the body thereat. As hereinbefore stated, the shifting of the body'is very important, as it causes the material to be thrown a greater distance to the rear of the wagon.

As clearly shown in Figs. 7, 8, and 9, it will be seen that the secondary bearings consist of hooks formed on the rear ends of the bracketplates and a concaved block secured between said plates.

W'hileI prefer to construct the pivotal bearings as herein described, and shown in the drawings, at the same time they are subject of many modifications. Therefore I do not wish to limit myself in this respect.

To the sides of the body A, adjacent to the bottom thereof,are secured guards f2 f2,which serve to prevent any material or substance from accidentally droppin g between the body and side bars a ct of the supporting-frame while the body is being loaded, which might interfere with the tilting of said body. Said guards consist of angle-bars riveted to said sides and projecting over the side bars a a, as clearly shown in Figs. l and 4, and they also serve to further stiifen and strengthen the body.

In reference to the tilting mechanism it will be observed that the two pairs of levers jj and 7c 7c when in their folded condition, as shown in Figs. 1 and 2, securely lock the body against accidental tilting, and, furthermore, the worm-gearing effectually holds the body at any angle of inclination.

IVhile I have shown only one side of the wagon-body provided with hinged doors, still at the same time both sides may be equipped, in which case I arrange the shaft or rod q', as shown in Fig. 15, for turning the worm o', in order not to interfere with the opening of said doors. In this instance said shaft q' extends horizontally along the supportingframe, and jonrnaled on the same, as indicated at g2, and to the forward end of said shaft is secured a bevel-gear h2, which meshes with a like gear t2, secured to the lower end of a vertical shaft j2, journaled in suitable bearings k2 at the side of the seat, said latter shaft being provided with a hand-wheel Z2 for posed to swing turningthesame. However,Iprefertosimply drop the forward end of the shaft q'.
