8 Claims. (01. 298-20) This invention relates to dumping wagons and to a convertible body therefor. Referring initially to the dumping feature, it is an object to provide a chassis having brackets on which the body or bed frame is oscillatable, and in which means are provided for holding the bed frame in a substantially horizontal position during the hauling or moving activities, and providing means by which the holding means are operated to release the rear portion of the bed frame in order that it will rock on pivots and move to an inclined position with the rear enddipped, as compared with the front end, which front end would be slightly raised, for a purpose to be, presently explained.

It is an object of the invention to provide novel means for supporting the rear end of the bed frame and whilethe bed frame is being elevated to the dumping or unloading position, the said means acting as a pivotal support for the rear end of the bed frame while the front end is being propped or elevated by means to be presently described.

It is furthermore an object to provide latch bolts which act in conjunction with brackets secured to the side members of the bed frame near their outer ends, which brackets have apertures for receiving the latch bolts, whereby the bed is held or supported in different positions of adjustment; and it is furthermorethe purpose of the-inventor to provide springs for operating the latch belts through their seated positions,

and to provide mechanicalmeans operated by a.

which will hold the wagon against being pushed rearwardly while force is being applied to raise the bed frame and, to that end, novel means are provided adjustably associated with the chassis which can be elevated out of operative position or lowered into operative position, as will presently appear. a Y

A still further object of this invention is to provide means for raising the front end of the bed frame by power applying instrumentalit-ies and, in this connection, thechassi's at its front end is provided with a bracket on which a sleeve is mounted, through which a tongue is slidable, and the said tongue is associated with links or props, the outer ends of which are pivotally connected to the tongue and the inner endfi Q? which are pivotally connected to the bed frame, and they are operative to lift the front end of the bed frame after it has been elevated to a certain extent by reason of the movement 7, of the bed frame on its trunnions, and the rear end by gravity descendsfrom the'horizontalto the inclined position, and it is the purpose of the inventor that the. tongue shall be connected to a source ofpower, such as a tractor, which will move the tongue inwardly in its guide and thus,

bring into action the lifting rods or links, to which reference hasbeen made.

Itv is afurtherfobject of the invention to facilitate the movement and guiding of the wagon by the employment of caster wheels suitably mounted on a bracket which is rotatably held in assembled relation with a plate carried by bled relation to the late which is mounted on.

the bed frame and thereby the caster wheels can be turned to facilitate the guiding or 10- eating of the wagon.

With regard to the convertible body, it isan object of the invention to provide a bed platform or bottom having sides hingedly connected to the bed frame through the use of brackets .attached to the said bed frame, with relation to which, standards to which the sides of the body the bed bottom and provide a Wide deck'for loads which do not have to be restrained at the sides of the wagon.

It is furthermore an object of the invention to' provide extension brackets whose ends telescope into the standards which are hollow or tubular, and the said extension brackets are provided with-extension sides of the body so that the said body may be deep when the auxiliary sides are in place;

It is furthermore the purpose of the inventor to produce a wagon of the character indicated -which has a great variety of uses as compared added functions as '7 compared with ordinary trucks or wagons, it is comparatively inexpensive to produce and maintain.

With the foregoing and other objects in viewy: the invention consists in the de'tailsiof. construc-; tion, and in the arrangement and combination 6 of parts to be hereinafter more fully set forth: and claimed.

In these drawings l0 "denotes thesidre'rails-of a chassis frame, .eachhaving a bracket I; I between its ends offset forwardly of the jlongitudinal center of the side rails and provided-with bear-- ings. I2, for a purpose to be presently explained. At the rear end of the frame'there is mounted between the side rails, a supportingmember- I3 on which a plate 14 is oscilla'tively mounted and" it extends transversely of the supportingmemben- There is a link 15 pivotally connected to-thezplate:

on each side of the pivot l6,'-fby whichrthei-plate' is oscillatively' connected tozthe .support," and .one such link is employed 'on'eachyend -of:.the plate, and the plate is provided with slotsgsuchrasrei 1p in.which the pivotlB-by which'the-l-ink.l5*is-connected to-theplate is'slidable; Theouter endzof the. link is pivota-lly connected toa *rodglS which: extends from a plunger ,b0'lt-.20;which operatesin a sleeve or guide 2 I mountedon thesideframe. of the chassis. Suitable bushingsll are provided in which the plunger bolt is slidablauand the. chassis frame has angaperture throug which the plunger .bolt reciprocatese. The. .plungerbolt. is undenpressure of a spring ,23 .located in the sleeve.

or housin and thesprin opg at sltoforce t e lun er -bolt. normally outwardly throughthe chassis frame for the purpose of holding. the bed. frame at different positions of adjustment;'as.will presently appear. The plate M has an arm-2t rigidly connected to it and it projects outwardly "the. links 15 and they in turn will retract the bolts against the action of the spring. The parts, it isunders-tood; are duplicated on each side of the chassis frame, and the bolts are intended to hold the bed frame in different positions of adjustment.

The-bed frame 26:is"(see-Figure 4) preferably of;rectangular construction and on the side thereof,,jtrunnions UIjpiVOtS. 21' are mounted, secured to itheframe"by-welding,-or the like, and the.

trunnions operateinithe bearings l2 which are preferably;babbittedvorotherwise lined to pre-.

vent wear on the brackets; and the said trunnions support the bed while-itis being transported, but provision made :for' dumping the wagon in 5 which operation the trunnions leave the bearings and "are -elevatedthereabove, so that the bed frame with the; bed" is-carried to the dumping position by means to-be presently explained.

Nearthe rear of the chassis frame, brackets 28 .are provided, one on each side of the bed frame;and thesebrackets are provided with apertures-29 which-are intended to selectively receive the: plunger-bolts which have been described: Whenthewagon is'intransporting position, thezbed 'is supported approximately horizontallyby'the trunnions-0n their brackets and by'plu'nger boltswhichenter the lowermost of the apertures 29 in the brackets 28,'but when the-load isto be dumped, the plunger bolts are retracted from the-lo'werof the series of holes in'the brackets and'by-gravity the rear end of the bed frame-and bed-descend until one of the other apertures'in'the brackets alines with the plunger-bolts; The--plunger bolts would be re- 4' leased to enter either-"of the holes, according to the inclination which the bed should have for effecting--the-dumping-- operation at that stage of the--operation;- *If the load were to be precipitously discharged, the uppermost hole 29 would be made' to' register with the plunger bolt before-the plunger bolts were released by the operatorpso that the-brackets would then be hinged on the chassis frame with the bed inits greatest- -inclination,whereas if only a moderate-discharge of the contents of the body ortruck were desired,{the-plunger bolts would be =released so thatthey would enter the intermediate hole inthe bracket, and thus the rate of discharge would -be lessened, as compared with the first mentioned operation.

It" is 'believed that-the coactive 'results of the mechanism so far described will be understood from" the description accompanying the reference to-the' several-parts and their relation to other 'partsof the wagon."

b-e-of more or'less'conventional form, but there is shown =a preferred form "of construction in which the'chassis frame has diagonally disposed braces 30 and 3| connected to the sides of the chassis frame, and these braces converge and their ends are connected to longitudinally disposed struts 32 which maybe connected to-the sides of the chassis frame in appropriate manner.

A bracket is connected to the front end of the frame structure and itcomprises side plates 33 each having angularly disposed'ends 34 and 35, and the said bracket further comprises a yoke 36 which, with the side plates 33, is connected to the chassis frame by fastenings 31 extending through the angularly disposed portion 34 of the side plates, the members 3| and 32 of the chassis frame, and through one side of the yoke, this fastening being in the nature of a bolt which may be secured in place by a'key 38. A housing or tongue guide 39, which is preferably rectangular in cross section, is supported'by the bracket and it has an aperture l-[iv through which a securing or king pin 48a may be inserted, which pin is intended to hold the tongue in different positions of adjustment. Thetongue is slidable in the housing and it is provided with a plurality of apertures 42 by which the tonguemay be held in different locations with respect to the housing. It is intended that the tongue should have ,a coupling 43 at its outer end by which it is connected to a tractor or source of power, and when the tractor is pulling the load, the pin will be inserted in the aforesaid apertures of'the housing and tongue, but when the load is to be dumped, the tongue is to be freed from the influence of the king pin 45a so that the tongue may slide rearwardly in the housing; and furthermore, the rear end of the tongue has a detent M which will engage the inner end of the housing and limit the outward movement of the tongue. a f

Rods or links 45 have their outer ends pivotally connected to the tongue through the medium of a bolt 48 extending through a bracket ll on the tongue and through apertured plates 38 on the outer ends of the links. The inner end of each link has an apertured arm mounted on a pivot 55 of a bracket 5|, one of which is secured to each side of the bed frame.

Assuming that the bed has been allowed to gain an inclined position, the frontend thereof will be elevated to such a degree that when the tongue is moved rearwardly, the links will exert a pressure upwardly onthe front end of the bed and move it to a position where the load will be discharged and it may gradually assume this position according to the movement given the tongue under the influence of the tractor, as shown in the drawing. When the bed is to be moved to its horizontal position, the plunger bolts are released and, with slight pressure on the front end of the bed, the bed may be moved onits trunnions to the horizontal position and when the plunger bolts ar released, they will enter the apertures. in the lower ends of the brackets.

As a means for facilitating the guidinglof the wagon and locating it'in positionfor discharge of the load, a caster wheel (see Figures 12 and 13) is employed at the front end of the chassis frame instead of the usual front axle and wheels em ployed in such trucks. The caster wheel, in the present embodiment of the invention, is associated with a top plate or bracket 52 which is horizontally positioned but which in mounting it on the chassis frame requires. the employment of a wedge plate 53 which extends from one side to the other of the chassis frame, and it has a beveled upper surface conforming to the angle of inclination of the chassis frame in order that the top plate may be horizontal and in order that the rotating parts of the caster wheel will'be parallel thereto and also that the axle of the caster wheel may be vertically disposed at right angle to the top plate.

There is a bar 54 in front of the wedge plate which extends across the members between the side bars, and it is connected to the'sid'e bars to strengthen the structure for the tongue housing. A plate 55 rotates under the plate 52 and the plate 52 has a recess 56 into which a spring-pressed detent or pawl 51 is seated, for the purpose of holding the caster wheels against undue vibration or shimmying, though thecaster wheel and the plate 55 may turnindependently of the plate 52 while the caster wheel bracket is turning.

A sleeve 58 is attached to or integral with the plate 55, and a wrist or king pin 59 is located therein and projects at the end thereof, the said pin being also extended through the plates 52 and 55. The sleeve 58 has a base plate 60 attached to it and it is braced by check pieces 61 integral therewith, and the cheek pieces are welded to the sleeve so that a rigid bracket is produced extending from the sleeve, and the plate so is provided with a bearing 62 in which a shaft (33 is secured,'the said shaft being provided with suitable spindles (not shown), on which the caster wheels 64 are rotatably secured in appropriate manner, and as the details of construction of the caster wheels may be changed to suit particular requirements, it is believed that those skilled in the art will understand the manner of their mounting. The bearing is secured to the plate 60 by a plate-and bolt assembly, generally identified by the numeral 64a, and the lower end of the wrist pin 59 is secured in place by fastenings, such as nuts, 6%.

It is the purpose of the inventorto provide a convertible bed or wagon body by which the capacity of the bed may be augmented by the addition of side boards, with novel means by which they are applied to or removed from the body frame, and there is provided a plurality of supporting members or brackets each comprising two side plates or cheek members 65 which are connected by a plate 66 secured to the sides of the body frame. Tubular standards, such as 61, are pivoted to each of the brackets through means of a bolt 68 extending through the cheek pieces and through the standard. The standard has an angularly disposed foot 69 projecting from its side which is intended to abut and bear against the side frame member when thesaid standard is in horizontal position, that is to say when it is movedoutwardly so that the side it of the body assumes 'a horizontal position in alinement with the bottom of the bed in order that the bottom of the bed and the side of the body form a deck to which loads may be applied if the load is not susceptible of being dislodged from the side of the deck. Such commodities could be visualized as filled-bags or the like.

Another modification or utility associated with the wagon bed -may comprise extended side boards H whichare attached to brackets H, the ends I3 of which are lodged in the tubular standards, and it is obvious that such modified construction would considerably increase the capacity of the bed of the wagon, and the side boards, as Well as the supplemental or auxiliary side boards, would be held in their upright positions by braces or rods 14 having hooks 15 engaging eyes 16 anchored in the Sideboards, or

other appropriate means may be provided for strengthening the structure.
