ROBERT MATTHIES AND JOHN A. SHEPHERD, OF HAMMOND, INDIANA.

DUMP-BOX.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed July 23, 1909. Serial No. 509,210.

To all 'wh-0m t may concern.'

Be it known that we, ROBERT MAT'rHIns and JOHN A. SHEPHERD, citizens of the United States, residing at Hammond, in the county of Lake, State of Indiana, have invented a new and useful Dump-Box, of which the following is a specification.

Our invention relates to improvements in dumping wagons and consists in certain novel features of construction, arrangement and combination ofparts illustrated in the accompanying drawings,... and hereinafter first fully described and then pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of a dumping wagon embodying our improvements. Fig. 2 is a bottom plan view of the same. Fig. 3 is a front elevation thereof. Fig. 4 is a transverse vertical section showing the doors on one side closed and those on the other side opened. Fig. 5 is a side elevation of a modified form of the invention, and Fig. 6 is a front elevation of the same.

Our invention relates to the construction of the wagon box, and the box embodying our improvements may be used in connection with any form of running gear, for which reason the running gear is not illustrated in the drawings.

The sides and ends of the wagon box are formed of wood and connected by suitable angle irons for the sake of economy, but the entire body may be made of metal if so desired. The front end 1 may be construct-ed of a single board or a plurality of small boards, as may be preferred, and the sides are constructed of one or more boards 2, the ends of which project slightly beyond the front end 1 and are joined thereto by angle irons 3 whereby a rigid and strong corner will be provided. At the rear end of the box we employ an angle iron 4 which extends around the sides and under the bottom, to which straps 5. are hinged at their lower ends, as shown at 6, the said straps 5 being secured to transversely disposed boards 7 constituting an end gate which may be swung down to form an apron at the bottom of the wagon box when the load is in boxes or sacks so as to permit the discharge of the load in the ordinary manner.

Arranged longitudinally within the wagon box and extending from end to end of the same is a T-iron sill 8, the rear end of which is secured to the angle iron 4, and the front end of which is secured to an angle iron 9 constituting a cross sill and secured to a transverse bar 10 which in turn is secured to the lower edge of the front end of the wagon box. Near the front and rear ends of the wagon box bolsters 11 are secured to this central longitudinal sill 8, and the ends of the said bolsters are suitably notched to fit upon standards or other parts of the running gear. Upon the front side of the front bolster and the rear side of the rear bolster we secure supporting strips 12 upon which are secured the ends of longitudinally disposed boards 13 which constitute iioor sections for the wagon box at the ends of the same. Above these floor sections 13, and

extending between the innermost edges of the same and the adjacent ends of the box, are removable guide boards, indicated at 14 in dotted lines in Fig. l, which serve to given the wagon box a hopper-like formation so as to direct the contents of the box to the dumping doors in the operation of the invention. At intervals along the depending portion of the T-shaped sill 8 we secure brackets 15 which carry a hinge shaft 16 upon which are fitted eyes 17 formed at the inner ends of brackets 18 secured to the under sides of the inner doors 19, the said doors being thus hinged to the T-shaped sill.

The outer doors 20 are hinged to the sides of the wagon box by means of hinges 21 having their members secured to the wagon box and the door respectively. The operating chains 22 have their inner or lower ends secured to. the hinge shaft 16, or to collars 23 rigidly secured thereto, and extend outwardly therefrom under the doors and through guides 24 on the undersides thereof, and then u'p along the sides of the wagon box and have their outer ends secured to the free ends of crank arms 25 rising from rock shafts 26 which are journaled upon the sides of the wagon box and have their front ends provided with operating levers 27 which project inward in front of the front end of the box. It will readily be seenthat if these operating levers be thrown upward and outward the crank arms 25 will be swung outward and downward, whereupon the weight of the contents of the box will force the

doors

19 and 20 to drop and permit the discharge of the said contents.

It will also be seen that the doors are arranged in two pairs, one on each side of the central longitudinal sill 8, and that a lever isprovided to operate each pair of doors so that the doors may be operated simultaneously or independently, as may he desired.

The doors may be opened to their fullestextent so as to permit a quick discharge of the entire contents of the wagon box or junction of the operating lever and the rock shaft, as shown most clearly in Fig- 3. The

lever and rock shaft with the doors operated' thereby may be held at any desired position by throwing the dog 28 into engagement with the proper notch in the plate or quadrant 29, as will be readily understood.

A foot rest 30 is provided at the front end of the wagon box and is secured to the same by brackets 31 which are fastened to the underside of the foot rest and to the lower edge of the front of the wagon box, as will be readily understood.

The seat consists of a board 32 secured upon the upper sides of angle irons or straps 33 having their upper horizontal portions rigidly secured to the under side of the seat and their front Vertical portions hinged to the outer side of the front end l of the wagon box so that the seat may be turned A forward and rest against the front end of the wagon box o-ut of the way when the box is being loaded.

In Figs. 5 and 6 we have shown a modified form o-f t-he invention in which the rock shafts 26 are dispensed with and pulleys 34tare mounted on the sides of the box. The chains 35 which are secured to the longitudinal T-shaped sill, and pass under the doors in the same manner as in the arrangement shown. in the other figures of the drawing, pass over the said pulleys and are then carried` to the front end of the wagon box where they are secured to operating levers 36 which are fulcrumed upon the sides of the box at the front end of the same and are provided at their lower ends with notched segmental plates 37 engaged by pawls or dogs 38 pivoted upon the sides of the box in advance of the said notched plates, as clearly shown in Fig. 5. The operating levers 36 are formed into curved arms 39 at an intermediate point of their length so as to present a curved guide or support upon which thechains 35 will ride in the operation of the device. As clearly shown in Figs. 5 and 6, the levers 36 are so Vdisposed that their upper ends will be with- -in convenient reach of the driver from the seat.

From the foregoing description, taken in connection with the accompanying draw-v ings, -it will be seen that we have provided a dumping wagon of a simple and strong construction which may be easily operated land by which the load will be eiiiciently held against premature discharge. /Nhen the doors are in their closed positions they lit up snugly against the lower edges of the sides and ends of the box and against the overhanging flanges of the central longitudinal T-shaped sill so that no open spaces will be :left through which the contents of the box be lost. a y In order to prevent wear on the lower @edges of the sides of the box by the contents of the same in the act of unloading, we pro- `lvide wear plates 40 which are secured to the inner faces of the sides at the lower edges gof the same, as clearly shown in Fig. t. @The greater portion of the weight ofthe load of the wagon box is borne by the T- shaped sill 8 so that the strain upon the :sides and ends of the box is much less than `in prior forms of dumping wagons.

In the usual use of the wagon, the guide boards 14 will be employed so as to direct the contents of the box toward the dumping ydoors andy prevent the same accumulating `in t-hevfront and rear corners, but if the box is to be used to transport'articles in boxes or sacks or other forms of'bundles, the said guide boards will be removed, and then when the box is to be unloaded the end gate 7 will be turned outward and downward and the load discharged over the same in the usual manner. This manner of using the box will be facilitated by making the Hared portions of thevsides removable.

- Having thus described our invention, what we claimV is:

A dumping wagon body, having an open bottom, a central sill T-shaped in cross section extending longitudinally thereof', brackets secured to the vertical terminal of said sill and longitudinally thereof, a longitudinally disposed hinge shaft carried in said bracket, a pair of longitudinal-.bottom doors lupon each side of the sill, having one member of each pair hinged to said shaft at each side of the sill and theV other members hingedv to the lower edges of the sides of the wagon body, flexible elements attached at their inner ends to the shafts and extending under the doors, guides located under the doors and through which said flexible elements pass, av rock shaft journaledupon each side of the body, a series of arms cary as our own, We have hereto aitixed our sigried thereby and engaging the outer ends of natures in the presence of tWo Witnesses. the flexible elements, and a handle for each ROBERT lVLATTHIES. rook shaft operably connected, whereby the JOHN A. SHEPHERD.

5 exible elements are drawn through the guides to close the doors.

In testimony that we claim the foregoing Witnesses:

WILLIAM J. MGALEER, ROBERT MCALEER.
