of Lansdowne, in the county of Delawarev and State of Pennsylvania, have invented certain new and useful improvements in Dumping'Wagons 'whereof the following is e specification7 reference being had to the accompanying drawings.

vMy invention particularly relates to dumping` wagons of die class usuaily einpioyed in conveying loose material, suoli as sand, coal, bricks, etc.7 which may bedis` charged in bulli, and in which the body is so supported upon the supportingJv structure as to heve an oscillatory movement whereby it may be tilted to discharge its contents or load. in previous constructions of this character, in so for as if am aware, it has been Vnecessary to apply soiue force other thangravity to cause the receptacle or body of a wagon or similar vehicle to tilt to discharge its load and to cause the reeduiust ment of the same to its normal position.

One of the objects oiE my invention is to provide wagon having an oscillatory receptacle or body which wiil automatically tilt to discharge its contents or load ivneri the driver withdraws the liitcli trigger or other moans which may be used for holding the bod;v in its normal position and which receptacle or body will roodjust iisel autoinetioai to noi'nal position ailier its load has been `ychir-fred. Other duni 1g wagons of this or ctcr wiiicli have been heretofore constructed require, iis nirezidy indi cated, some force other than und in addition vto gravitj to canso the receptacle bony to completely and aiiioinaticznly perform the acts of iiiting to discharge its contents oi' load and readyiis nent to norinal i'iositioii.

The opeu lon of discharging the contents or ioad from the receptacle or body has genu ernlly been performed heretofore in 'three distinct acts,--iiist, by tilting the body, usnailyP by hand, to a dumping position; second, the dumping oi' the lood7 which is the act of gravity: and third, the resdjnstinent of the ieceptacle or body which may be per formed iA` voi-ions By the employn mont of my invention these o? the ieccptacie or body, discharging toe contents oi1- lood therefrom, and the ieadjiiflit-` nient oi 'the receptacle or body to its .noi-moi position are perfor-fied by the oli tiltingr I gravity and require no other force to effect o cornnlete operation. The peculiar and novel construction and arrangement of the parts of the structure embodying my invention? maire this possible. in a structure einbodying my invention the axis of oscillation of the ieoeptaole 0r body is so situated that the center of gravity/thereof is in front of the axis of oscillation from normal position when the said receptacle or body is empty7 while the center of gravity of the combined weights of the receptacle or body and its contents or load is situated in rear of such axis of oscillation.

In the structure embodying my invention have also provided means for utilizing the tail board of the body or receptacle as e countrwweiglit, whereby a siiiicient amount Vof energy may be accumulated to readjust the receptacle or body to its normal position after the load is dumped or discharged.

At the time that the receptacle or body tilts to discharge its ioad the tail-board which acts as a counter-weight is raised. This counter-weiglit assists in causing the body to readjust itself to normal position.

'The tail-boord in acting as a counter-weight or potential energy accumulator thereby becornes the by which the kinetic energy exerted. in dumping the load may be used in effecting roadjlistment oi' the body,

Further objects of my invention are vto provide a construction in which the axis of osoiliation oi the receptacie or body from its normal position lies in a plane forward oi' the :ii/Lie of the rear wheel of the wagon so that the weight oi the receptacle either empty or loaded is disposed on the wagon botween'tlie front and rear axles and so that suiicient weight is thrown upon the front wiioeis oi said wagon to prevent lateral skid .i ing; o 4provide the receptacle with iin auiiiiinry airis of oscillation rearward of the rear lwie of the wagon., upon which asis the receptacle may rock ofte-r oscillating on the main axis suiiicieiitiy to shift the center of gravity of the load bacli of the plane of said auXiiiai-y airis; and to provide means to maintain the recept-icio in :i fixed oscillatory path with respect to the wagon frame; to pro vide means to retain the receptacle in its normal or operative position, to provide ineens release said receptacle; and to pro- 7"ide a tnii gate arranged to be automatically 1 l ont noi-mal position by die dumpo f illustration; Fig. 2 is a fragmentary, sec-A Vtional view of theiwag'on shown in Fig. 1,

carried by the receptacle; Fig. 4 isa-fragmentary plan sectional view of one of the uides and its respective guide-way; and `ig. 5 is a diagrammatic plan yView on a reduced scale of the receptaclev per se.

In said figures the frame of the wagon is supported upon the front and rear axles 7 and 8, respectively carried bythe wheels 9 and 10 and comprises the side rails 12, preferably .formed of angle irons, .which are looped upwardly atl 14 to provide a mounting for the seat bolster 15 carrying the springs 16, upon which the seat 171s mounted. Said side rails 12 ane, cpn/sniettly braced intermediate of lthen by the cross beam 19 and their horizontal webs, each carry a bar 20, which extends rearwardly over and slightly beyond the rear axle 8 of the wago and 1s slightly deflected downward as shown at 21. Attached to the vertical flange of each of the respective side bars 12 are the rearwardly extending bars 22, which extend 4obliquely upward from the rear axle 8 and terminate in a verticalextension 23 in close proximity to the rear end of the receptacle 25. The receptacle 25 is mounted for oscillation upon said frame I and is provided with a supporting member or chair 26, which has a relatively short bearing surface 27, and which extends obliquely upward from the opposite ends of said short bearing surface, and is provided with extensions 28 and 29 respectively secured to the under side of the floor 30 of the receptacle 25, and to cleats 31, 32 and 33 on theunder side of the-floor.

As best shown in Fig. 5, the receptacle 25 is formed wedge-shaped, havin its minimum width at its forward end, and its maximum width at its rearward end, whereby its center of gravit when empty is farther toward the forwar end than when loaded,

so that when its center of oscillation is disposed between the center of gravity, when when loadempty andthe center of gravit ed, it will tend to automatica ly return to detent ate ofts ends upon the pintle 61 to the lugs i,iaagasm.

its normal. position when empty and when the bar 2O as best shown in dot and dash line in Figs. 2 and 3 until theextension 28 of said supporting member engages the end 21 of said bar 20 upon which it rocks as a center, entirely raising the chair 26 from said bai' 20 and providing an auxiliary axis of oscillation which is farther back than the axis of oscillation 38 and upon which the receptacle 25 with its load continues to oscillate until it reaches the -position shown in Fig.,2, at such an angle as to permit the load to slide'tlierefrom.

In order to maintain the receptacle 25 in a fixed path relative tothe frame of the wagon, said receptacle is provided with guide bars 40 respectively secured to the opposite sides of the receptacle, by bolts 41.

.Each guide 4U is provided with a down-- wardly and rearwardly curved projection 42, whichextends through the guide way 43 formed by the strap 44,- which the bar 22 by bolts45.

The oscillatory movement .of` the recepis secured to vtacle 25vupon its axis of oscillation at 21 is limited by a pin 48 carried by the curved projection 42 of each of the guide bars 40,

the under side of the axis strap 49 of the wagon frame. Y

The tail gate 50, which forms the rear wall of the receptacle 25, is' provided with forwardly and upwardly extending arms 51 which 'extlend straight for a distance from said tail gate-and then curve upwardly, and are pivoted at 53 to the upper endvof the respective guide bars 40.

' which pin, as best shown in Fig. 2 engagagesA The arm 51 of the tail gate 50 is arranged to ride upon the roller 54, which is mounted for rotation upon the shaft 55 in the upper extremity 23 of the bar 22, said arm 51 be# ing of such shape as to effect the uplifting' 50 when the receptacle?4 is of the tail gate shifted to the dumped position shown 1n- Fig. 2, so that when theload is discharged from said receptacle, the tail gate servesto start the rocking of the receptacle upon its w rearward axis of oscillation back to its nrmal operative position, until fitted to form the end closure of the receptacle 25 as show!!l in Fig. 1.

The receptacle 25 is retained 1n its normal operative position as shown'in Fig. 1 by :af

lever4 60, which is pivoted intermedi- 62 of a plate 63 secured to the under side of the seat bar 15, and between the upper ends of a pair of plates 64, which in turn are se this pin, however, is not and intermediate the" altitudinal limits thereof. The lower endY of the detent lever 60 is arranged to engage adetent bracket- 65 secured to the front wall 66 of the receptacle 25 and is arrangedA to normally retain the receptacle in it operative position shown in F ig. 1. Said detent lever 60 is connected by the chain 68 to the foot lever 69, which is pivoted at 70 and arranged to be shifted in the direction indicated by the arrow thereon in Fig. 1 'to'disengage said detent lever 60 from theldetent bracket 65, in opposition vto the ytensionV Aof the spring 72, which normally tends totshift said lever 60 to its operative position to engage the detent bracket 65. I

The' foot lever 65.) is arranged to oscillate in the guide 75. which is provided with an aperture 7G into which a pin 77 may be fitted to prevent the accidental movement of thel foot lever to effect the premature duinping of the load carried by the receptacle 25';

an essential elenient butiis merely a preventative to insure against carelessness. wagon constructed in accordance with the invention is advantageous in that the operator may actuate the dumping mechanisni without dismounting from the seat 17 or without releasing control of the team, and by merely proceeding from the discharged contents ot' the receptacle 25, may eilect the automatic return of said receptacle to its normal operative posit-ion.'

lt is not desired to limit this invention to the precise details'of construction andarrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features yot' the invention as defined in the appended claims.

llaviiie' thus described my invention I Y claim:

l. ln a dumping wagon con'iprising' a frame, the combination with an oscillatory receptacle arranged to carry its greatest load rearward of the plane of its center of gravity, of a supporting member having a relatively short bearing surface slightly 'rearward of theenter of gravity of said i'eceptacle when empty, and arranged to rest upon said frame forward of the rear axle of said wagon, said receptacle being arranged to first rock on the corner or said support,

and to thenv rock upon the rear corner of .said frame, rearward of said axle, curved guides carried by said receptacle, and guideways carried by said frame coperative with said guides to maintain said receptacle in oscillatory relation with said frame.

2. In a dumping wagon comprising a frame, the combination with an oscillatory receptacle arranged to carry the greatest load rearward of the plane of the center of gravity, of a supporting member having` a relativelyr short bearing sui-'fatte slightly rearward of the center of gravity of said receptacle `when empty and arranged to restupon said frame forward of the-rear axle of4 said wagon, said receptacle being arranged -to first rock on the corner of said support and then to rock on the rear corner of said traine rearward of said axle, curved guides carried 'by said receptacle, guide-ways carried by said fraaie coperative with said guides to maintain said receptacle in oscillatory relation with said frame, arms eX- tending upwardly and rearwardly from the opposite sides of saidA frame, pivoted arms having pivotal connection with the said guides and being provided with a tail-board upon their outer ends and being supported intermediate their ends upon the arms extending upwardly from said frame.

In witness whereof, I have hereunto set inyfhand this 17th day of March, A. D. 1911.
