To all whom it may concern,.-

Be it known that we, ALFRED M. CHAFFEE and llnRBnRTA V. CHAFFEE, both citizens of the United Statesresiding at Oxford, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Dumping-Wagons for Coal, &c., of which the following, together withthe accompanying drawings, is a specification, suffici ently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and'use the same.

The object of our present invention is to provide, in that class of wagons used for the delivery of coal andother materials, a powerful, ecient and easily operated mechanism for giving a tilting or'dumping action to the wagon-body. p Also, to produce alight, strong and durable wagon and to improve the struct- 'ural detail of the mechanism to render the apparatus more perfectly adapted!V to the pur- `our dumping wagon. Fig. 2 is a rear end view of the same.

Fig. 2a shows detail of the end gate holder.

Figs. Band 4 show details of the lifter-bar, its supporting roller and connecf tlons. Fig.`5.is a plan view of the running gear, supporting frame and operating mechanism with the body removed. Fig. 6 is a bottom view ofthe body and delivery chutek attachment. Fig. 7 is a part of the chute in plan view. Fig. 8 is a perspective view of the chute attachment.

The construction and operation of our dumping wagon are as follows:

A `A denote two longitudinal bearers or sills disposed parallel to each other at a distance apart corresponding to the width of the wagon-body B, and connected togetherrigidly at or near their forward ends by transom bars a a, which are secured to the center-plate or circle e, whereby the structure is mounted on the swing-frame E carried by the front axle and wheels W; while at their rear ends said sills A are individually supported in connection with the rear axle W and wheels W', preferlof one of the sills.

ably on springs S arranged asindicated. The sills are made of approximately the same length as the wagon body, say eight feet,

more or less, and are preferably formed of a rectangular wood bar with metal reinforce plates A attached to the opposite sldes p thereof. (See Figs. 3 and l.) Diagonal braces a connect the sills and transom bars a and maintain the parts rigidly square with each other. 'Fixed to and projecting upward from lbackwardly inclined (see Fig. 1).. .f

A shaft F extends across the front of the `wagonloeneath the body B, and is provided with flanged rollers' F that are supported upon .and roll along the respective sills A, whichv latter serve as tracks for the rolls. Swinging strutsI or' lifting-bars H extend from the ends of the shaft adjacent to said rolls obliquely upward and backward to pivotl studs G fixed onthe sides of the body near its upper part, as shown; said bars being provided at* their ends with eyes that embrace the shaft and pivot, and form hingingjoints or iiexible connection therewith. The pivot studs G are best provided with sustaining straps g that are secured'to and pass beneath the sides of the body, as illustrated. y

' Suitable drag loops I are combined with the `shaftand rolls -F (see'Figs. 3, 4 and 5) carry-4 to be Wound upon or unwound from the same by rotation of the shaft, which can be elfected by the train of operating gears M arranged in connection with said winding shaft and supported in suitable manner at theouter side Said operating'gearing consists preferably of the crank receiving arbor m carryinga pinion m', the intermediate gear and pinion fm2 mounted on a stud xed in the frame, and the gear m3 fixed on the end y of the winding shaft, said gears meshing together as shown in Figs. 1 and 5. Astop dog IOO fr is provided for locking the gear train to retain the mechanism at any position of adjustment.

The winding shaft K is best provided with collars f that are rigidly fixed on the shaft and embrace the ends of the bearing boxes for retaining the sills against lateral displacement in relation to each other, thus avoiding the necessity of other framing therefor than the front transoms a.

Beneath the body there are two forwardly extending push-bars or rods L that have their rear end pivoted to an nn'der part of the body at L', and their front end formed with atransverse eye L2 through which the chain J is rove, as indicated in Fig. 5.

The rear part of the body is provided with laterally projecting studs Cv that extend through the slots clin the bracketsfor hinging and retaining the body in connection with the sills; said studs being best provided with caps that prevent lateral spread of the frames. The studs C and brackets D also hold the body from swinging sidewise at its forward end, the bars H in a measure assisting to keep the body in proper lateral alignment.

When in normal position the body rests at its rear end on the sills A and at its front end on the rolls F which lie on the sills at the position shown in full lines Fig. 1; the studs C occupying the lower end of the vertical portion of the slots ci in the guide brackets D.

In the operation for tilting the Wagon body, the operator places the crank h on the arbor m and by means of the crank and gear-train M rotates the winding-shaft K, winding in the chains J thereby drawing backward the shaft F to which the lift-bars H are connected the rolls F runnin g on the sills A causing the inclined lift-bars to assume a more nearly upright position and consequently elevatiiig the front end of the body while the rear end rests upon the sill (see dot-and-dash lines Fig. 1). When the body has reached the position indicated at B4 the rings i, or suitable stops on chains J engage the eyes L2 of the push-rods L. Also at such position the studs C have risen in the slots d to theinclined portion thereof; then the further winding in of the chain J while further elevating the lift-bars H also at the Sametime forces backward the pusli-rods L that are attached tothe body at L', thus moving the entire body rearward and causing the studs C to slide up the incline slots d thus effecting the elevation of the body to the position indicated at B5 on Fig. 1,'by dotted lines. The contents of the wagon can thus be dumped by releasing the end board B', or delivered through the endgate into the chute to be thereby conducted into the coal-hole or place of deposit. By reversal of this operation and the unwinding of the chains J the wagon body is readily let down to its normal position. By means of the rolls F traveling upon sills A, and the lift-bars H acting in conjunction therewith and the pivots Gr, a very powerful, efficient and easily operated apparatus is produced. Also, by the arrangement of the bars L and slotted brackets D the elevation of the body can be effec-ted in an automatic and highly satisfactory manner. y

By making the slots d vertical at their lower ends the body is retained against rearward movement until its forward end has been elevated to the desired degree and until the rings I have been drawn back to meet the eyes of the push-bars, thus rendering the operation more perfectly under control and regular in its order of action. Y

It is obvious that the rollers, lifting bars and winding chain appliances may be employed without using the slotted brackets D, the body being simply hinged at its rear end to the sills, or with the studs O serving merely as stationary .pivots instead of movable pivots; such arrangement may, in some instances, be employed but does not afford elevation at the rear of the body and is not therefore deemed as desirable as the form shown with the brackets vertically and obliquely slotted. The body is best provided with metal chateplates b along its lower part where the lifting bars H strike the sides thereof in the various positions of elevation.

The rear end board of the body is hinged to swing downward and is also provided with a delivery opening and closed by a sliding gate B2 as indicated; this gate we provide with notches n in one side (see Fig. 2?) and combined therewith we arrange a spring holder N having a flat portion that screws onto the frame, a spring portion n and a bolt or nose n2 that extends through the frame and engages the notch in the slide, and a thumbflange n3 for retracting the bolt.

Underneath the bottom of the body B we provide two parallel rods R R secured only Vat their front and rear ends to the body frame,

but also permits of the chute being swung to a position of right or left inclination, as indicated by Fig. 7. When under thebody the IOO rear end of the chute P is suspended by a 'to more clearly illustrate the action of the wagon-body adjustment and the mechanism for effecting the same.

What we claim, and desire to secure by Let- .ters Patent, is-

1. In a dumping wagon the side brackets having the slot therein for the body-retaining studs shaped as shown, thelower part of said slot to resist backward movement of the stud until. the wagon front is at a given degree of elevation, and the upper part to afford backward and upward movement thereof; in combination with the sills, lifting mechanism mounted thereon for elevating the body, and

. push-bars engaged and actuatedby said liftthe rollers and rol1-shaft carrying the lower ends of said lifting-bars, said rollers running upon said sills as a track, the windingshaft, y y

the chain connecting said rollers and lift-bar carrying devices with said winding-shaft, the push-bars pivoted to the body and having eyes that engage with said chain, and the crankactuated gearing for rotating said windingshaft, substantially as setforth.

Witness our hands this 3d day of March, A. D. 1894.
