' GaAvLEL DUMP;

Application file'dfNo vember To all whom/2'25 may-concern V Be it known that'I, THEODORE A. HAn UNe,

'a citizen of the United States, resid ngat Austin, in the countyof'Travis and State of Texas, have invented a new and useful Gravel Dump, of which the following is a specification. i

This invention relates to improvements in wvagon construction, and more particularly tion, novel means being provided for releasin the sections to accomplislrthe purpose of the invention. 7 h With the foregoing and other obe cts 1n view which will appear as the description proceeds, the invention resides in the c'ombi nation and arrangement of parts and in the details of constructlon hereinafter descrlbed and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing: v Figure 1, is aplan view of. a wagon bed coi'istructed in accordance with the invention."

Figure 3 is a sectional .view'taken on line 33- of Figure 1. 7

.Referring to the drawing in, detail, the wagon loody includes side boards 5 which are connected at their forward ends in any suitable and well known manner. p The side boards 5 are mounted on the channel irons 6 that are bolted or otherwise secured to the bolsters? on which the wagon body is supported, it being understood that the channel irons '6 extend theentire length of the body. f

The floor of the wagon bed or bottom includes a plurality of cooperating sections arran ed in parallel relation with each other as clearly shown by Figure 3 of the draw- Figure 2' is'a side elevational view' there- $3923. Serial No. 673,570. 1

ings'." Each-section is formed with a hinge 8 adapted to embrace the supporting rod 9 associated therewith, whereby the" sections may swing to theirfo'penor closed positions, at the will of the operator. As shown, lips 10 are :formed on certain sections of the floor, which lips overlie a portion of the adjacent hinged sections to prevent material frompassing between the adjacent edges of sections. The supporting rods 9 have their ends extended throughthe end members 11 forming a part of the wagon body.

The sections vary in length, the outer, or shorter sections being designed to fall to a discharging position; prior to the "moving of theremaining' sections so that portions of the load may 'bedumped independently of the remaining portion thereof. I "Slidably mounted at the ends of thewagon body are supporting bars 12fthat have their ends dis posed in slots *13 formed adjacent to the ends of the wagon body, so that theibars may slide throughout the length of the slots and allow the hinged sections forming th bottomto swing downwardly. In order that thehinged sections will closely engage the supporting bars 12, the ends of the sections extend upwardly at l4=where'. they overlie the supporting, bars 12.

- Extending through the side boards 5 at a point substantially intermediate their ends,

isa rod 15, the length of the rod being greater than the width of the wagon bed to allow the ends" of the rod 15 to extend beyond the side boards 5 where they support the arms 16, which arms have connection with the'rods 17 and 181'respectively at points'adjacent to the upperends of the arms whereby movement of the arms 16 produces a relative movement of the rods 17 and 18.

The rod 17 has pivotal connection with the lever 19 at 20, which is manuallytoperatedto cause a movement of the rod 17 when it is desired to operate the supporting bars 12. A dog-21 is provided on the lever 19 and is designed to hold the lever in various positions of adjustment. The lower end of the lever is pivotallysupported at 22 to pro vide for such 'movement of the rod, When the lever 19 is moved.

The rod 18 at theopposite side'o f the bed has pivotal connection with the bar 23,..at 24;, the lower ends of the bar being tapered and extended-into an opening formed in the supporting bar 12 associated therewith,

- movement of the bar 27 is accomplished by the movement of the arms 16.

The supporting bar at the rear end of the wagon body. is actuated by means of the arms 30 that are pivotally connected to the wagon body at 31 and have reduced end portions 32 extended into openings formed in the supporting bar associated therewith, the upper ends of the arms 30 having pivotal connection with the operating rods 33 that connect with the arms 16 so thatmovement of the bars at both ends of the wagon body will be simultaneous.

From the foregoing it will be obvious that upon movement of the bar 17 in the direc tion of the arrow as shown by Figure 2 of the drawing, the supporting bars at the end .of the wagon body will be moved away from the ends of the sections of the bottom of the body to allow the sections to swing donnwardly under the weight of the material supported thereby to discharge the load.

,When it is desired to'return the hinged sections of the wagon body to'their nori-nal [or supporting positions, the lever'3 l is operated. The lever 34 is pivotally supported at its lower end and has pivotal connection with the rod 35 that extends dow 'iwardly which in turn has pivotal connection at 36 with the supporting shaft 38 that is hollow and houses the rod 15 as clearly shown by Figure 3 of the drawings.

Secured to the shaft 38 at a point adjacent to 'one end thereof, is a collar 39 which carries an arm 40 formed with openings to receive the lifting links ll that have connection with sections of the bottom through the links 42 so that movement of the arm 40 will'result in a relative movement of the sections associated therewith.

' Collars 43 are also secured to the shaft 38 and are arranged in suitable spaced relation with each other to accommodate the members 44c thathav-e arms 45 formed integral therewitlnwhich arms have connection with sections of the bottom through the links 16. Shoulders 47 are formed on the collars 43 which shoulders are engaged by the laterally extending lugs 48 of the members 44- so that the bottom sections may be moved simultaneously from their open positions to their closed positions and at the same time permitting the bottom sections adjacent to one side of the wagon body may fall downward- 1y to discharge the contents or portion of the load supported thereby, without effecting the remaining sections of the wagon bottom, thereby permitting portions of the load to be discharged at the will of the operator.

It is therefore obvious thatv by operating the lever 19, to move the supporting bars slightly to disengage the shorter sections of the wagon bottom. the shorter sections will be permitted to drop partially rotating the shaft 38 and moving the shoulders 47cm of engagement with the members 44, while a further movement of the lever 19 will permit the adjacentsections of the bottom to swing downwardly while a still further movement of the lever 19 to mov the supporting bars out of engagement with the remainingbottom sections will permit the last mentioned sections to drop. 7 When-it is desired to return the sections to their normal or supporting positions. the lever 34 is operated moving the shaft 38, whereupon the shoulders 47 of the collars 4l3'contacting with the laterally extending lugs of the members let will pick up the members 4% and move them to theirnorinal positions. When the shaft 38 is rotated by a. movement of the lever 34, due to the fact that members 44: have connection with the bottom sections it is obvious that the bottom sections are moved upwardly or to their active positions. 7

It mightbe further stated that the movement of the rod 35 is restricted by the coiled spring 49 which has connection with the rod 35 to the link 50, the opposite end of the coiled spring being anchored at 61 to the body portion.

At the ends of the body portion are eye plates 32 through which hoisting hooks may be positioned when it is desired to lift the wagon body from the running'gear supporting the same. 7

I claimr In a dumping wagon "body, a sectional bot tom, means for permitting the -sections to be moved to their discharging positions independently of each other, a shaft'extending transversely of the body, collars loosely mounted on the shaft and having shoulders, collars secured to the shaft adjacent to the first mentioned collars and having shoulders adapted to cooperate with the first mentioned shoulders to move the first mentioned collars with the shaft when the shaft is rotated, and means connecting the collars to the floor sections disposed thereunder.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signatur in the presence of twowitnesses.

THEODORE AUGUST HARTUNG.
