DU'MPING-WAGON.

SPECIFICATION forming part of Letters Patent No. 730,607, dated June 9, 1903.

Application tiled October 7, 1902.

To (tZZ whom it may concern.-

Be it known that I, VIRGIL BROWN, of W'at-' rous, in the county of Mora, Territory of New Mexico, have invented a new and useful Improvementin Dumping Wagons, of which the following is a specification.

My invention relates to dumping-wagons,- my object being to provide a wagon of this character that will be strong, durable, simple in construction, economical in manufacture, easy of operation, and one that can be easily loaded. v

My invention consists in the novel features of construction andoperation which will now be poihted out and claimed in the appended specification and illustrated in the accompanying drawings, which form a part of this application, and in which Figure l is a side elevation of my improved dumping-wagon. Fig. 2 is a top plan view of the frame which supports the body. Fig. 3 shows an end elevation of a portion of my invention, the wagon-bed being in its dumped position with its normal position indicated in dotted lines. Fig. i is a perspective View of my invention in its dumped position. Fig.5, is a detail perspective view showing the con-' struction of the arms and levers usedat either end of my wagon-body for operating the gate.

My wagon includes a main frame upon which the body 1 is supported. This frame consists of the heavy longitudinal beam or plate 2, which is secured to the axles of the: wagon, the parallel bar 3, upon which the side of the Wagon-bed rests when in its normal position, and the transverse bars l, which connect the longitudinal bar 3 .with the main beam 2. This beam is secured, preferably, to the under side of the axles of the wagon in order that the body may be close to the ground,

. which is a decided advantage in the loading of heavy materials, such as stone, 85c. It is furthermore desirable to have the body located near the ground in order that it may not have so far to fall when dumped, which would only impart undue strain and jar and would also require'additional effort' to bring it back to its normal position. Atits rear end the beam 2 is bolted directly to the axle, while its front end is provided with the heavy iron plate 5, which is secured by bolts to the under side of the beam and projects a certain Serial No. 126,286. (No man.)

distance. in front thereof. The forwardlyprojeeting portion of said plate has a hole 6, designed to receive the king-bolt. (Not shown.) The hole 6 is located sufficiently in advance of the front end of the couplingbeam to prevent said end from interfering with Ihe' necessary oscillating movement of the front axle.

The brackets 7 are secured by bolts or screws to'the longitudinal beam 2 just inside the outer transverse bars 4. They are each provided withthe upwardly-extending parallel ears 7, spaced apart to receive the downwardly-extending lugs 9f of the body-plate 8, which are suitably secured to the wagon-body on its under side and are adapted to codperate with the plates 7 to form a pivotal conmotion between the body and the frame A of the wagon. The body-plates S are located slightly nearer to the dumping side of the wagon-body than'to the other side,which tends to im part to the said body at all times a slight tendency to dump.

The dumping-lever 9 is secured to the closed side of the wagon-body or the side opposite its dumping edge and is designed to assist in readily effecting the dumping process and also in bringing the wagon-body back to its normal position after its load has been dumped. This lever is preferably adjustably connected with the wagon body, so it can be swung out, as shown in Fig. 3, for

.use,or in, as shown in Fig. 1, when not in use, and is reinforced by a brace-rod 10, riveted at one endto'said lever and having an eye at its other end to receive the upper end of the bolt 11, the lower end of which bolt passes through an aperture at the inner end of said lever 9. The bolt 11 is held in proper relation to the wa on-body by the angle-bar 12, which is secured to the body by bolts and at either end has an outwardly-extending wing 2, provided with suitable apertures to receive the bolt, the lever and its bracerod being held bythe bolt ll between the wings 12*. 7

It will be seen that the lever 9 and its bracerod 10 are free to swing on the bolt 11, and when the lever is used to dump the wagonbody or to bring it back to its normal position .the same is swung out at right angles to i the body, as shown in Fig. 3, whereby the greatest possible amount of leverage is obtained.

The latch-bar 13 is rigidly secured to the frame of the wagon and projects outwardly from the center of the longitudinal bar 3. The wagon-bed is secured to this latch when it is desired to hold it in its normal position in engagement with the main frame, and the lever 9 is further utilized for forming the connection between the body and frame, as shown in Fig. 1, for it will be seen from Fig. 1 that when the latch is swung around against the side of the wagon-body, as there shown, the inner end of said lever will pass under the projecting end of said latch and it will be impossible for the bed to be dumped while the lever remains in that position. In order that the lever 9 may be secured in the position just described to prevent it from swinging out of engagement with the latch 13 and dumping the load at an inopportune time, I provide the drop-latch 14: for said lever. This latch comprises a bar slidable vertically on the wagon-body. The lower end of this bar is bent outwardly and upwardly and presents an inclined face to the upper side of the lever 9, so that when the said lever is swung around againstthe wagon-body it will engage the inclined end of the said keeper and will elevate it till it has passed behind it. The keeper will then drop downwardly by gravity and will prevent the bar from swinging outward.

I provide arms and levers at the ends of my wagon-body for automatically effecting the double purpose of lifting the gate thereof out of the way when it is desired to dump a load and for assisting in bringing it again into its normal position as the body is readjusted, so that one man can perform both operations by simply tilting the wagon-body by means of the dumping-lever 9. In order to effect this result, I provide operating-arms 16 and the auxiliary arms or braces 17. The arms 16 constitute swinging carriers for the dumping side or gate and are pivoted at their inner ends to the outer side of the ends of the wagon-bod y and near the top thereof. A boss 18 is interposed between the wagon-body and each arm at its pivotal point 18, which serves the double purpose of furnishing a good bearing for the pivot and of holding the arm slightly separated from the body in order that the upper ends of the auxiliary arms 17 and curved standard 19 may be easily received between the arm 16 and the wagon-body. The outer ends of the'operating-arms 16 and of the auxiliary arms 17 are bent inwardly at right angles to their main or body portions, and these bent ends hook around the outer side ofthe gate 15 and are bolted thereto, the former near the upper and the latter near the lower edge of the gate. The auxiliary arms 17 at their inner ends are riveted or bolted to the arms 16 and serve the purpose of braces to assist the said arms 16 in holding the gate 15 in proper position.

The device for controlling the position of the gate includes the curved standards 19, suitably supported on the longitudinal beam 2 of the main frame at each end of the wagonbody and extending outwardly and upwardly and provided in their upper ends with rollers 20, upon which the lower edges of the arms 16 rest. Since the supporting-standard 19 remains stationary, it follows that when the wagon-body is dumped the arms 16 and 17 will remain substantially where they were, as will also the side 15 of the body, which side they support, the gate being lifted slightly as the body reaches the dumped position. Hence when the wagon-body is dumped it will have moved downward from the gate 15, and the side of the body will be opened to permit the free emptying of the load. However, since the wagon-body is pivoted at its bottom to the frame and the arm 16 is pivoted to the body near its top immediately above the pivot upon which the bed turns and the standard 19 remains stationary it follows that when the body is dumped the inner end of the arm 16 will be slightly lowered and will also move somewhat nearer to the stationary roller 20, the effect of which will be to elevate the outer ends of the arms 16 and 17, together with the gate 15 of the body. The purpose of the roller 20 is to permit the free longitudinal movement of the arm 16 upon the curvedstandard 19. The farther out the arm 16 moves upon the roller20 the greater will be the lever-power which the side 15 of the wagon-body will exert to assist in bringing the body back to its normal position when the load is emptied, for in this case the arm 16 becomes a lever, the roller 20 the fulcrum, and the weight 15 the power to effect this result. This arrangement will not perceptibly affect the operation of dumping in its initial stage, but will retard it somewhat as the wagon-bed becomes more inclined. This, however, is rather an advantage than a disadvantage, for when the operation of dumping is once fairly begun there is a superabundance of power to finish it, so that my invention practically stores up a portion of the surplus power of the dump and utilizes the same to assist in bringing the body back to its normal position.

As will be seen from Fig. 4, the upper end of the supporting-standard 19 is provided with the keeper 19, and in the space intervening between the keeper and the standard the roller 20 is located, so that its pivot may be supported at each end. Through thisintervening space the arm 16 also passes. By preference I pivot the standard 19 at its i11- ner lower end to the wagon-frame at 19", as this will permit the lifting of the gate 15 by hand wherever desired Without tilting the body of the wagon.

In the dumping operation as the pivot-point 18 approaches the roller 20 it is evident that there must be sufficient vertical space between the arms 16 and 17 to permit the stand- ICC vec eor g ard 19 to be received between them, and in 1 order to provide for this the parts may be: looselyjointed or some of the parts may be bent to permit the desired operation, as preferred.

From Fig. 2 it will be seen that in the con-j. struction of the main frame of my wagon the transverse beams at thereof are provided at their inner ends with the iron plates a, which serve as large washers or clamps for the bolts that pass through them, so that the same may i be screwed up unusually tight without tearing or bruising the wood.

From the construction of the main frame it will be seen that one side of my wagon is somewhat heavier than the other, and in or-' der to counterbalance this slight additional weight on one side Iload the otherside slightly heavier, so that my wagon as a whole is evenly balanced, and the additional weight being on the tilting side of the bed will cause I 1 supported by the curved standard; and a it to dump all the more promptly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In dumping-wagons the'combination of the main frame; the latch-bar carried there- .by; the tilting body pivotally mounted on said frame; thehandle-lever for dumping said body; said lever being pivoted to the body and adapted to swing against the side thereofj lever whereby to lock the lever against the.

side of the body; a removable gate for the opposite side of the body; swinging carriers supporting said gate at their outer ends and pivoted to the body at their inner ends; braces for said carriers; controlling devices comprising standards pivot-all y supported on the main frame and having rollers bearing loosely underneath the swinging carriers, upon which rollers the carriers are free to move when the wagon-body is dumped; said swinging carriers normally occupying a horizontal position with their pivot-points above the tilting pivot of the wagon-body, whereby the dumping of the body not only causes said arms to move outwardly upon the controlling devices, but also elevates their outer ends and with them the gate as specified and set forth.
