Specification of Letters Patent.

Application filed May 12, 1909. Serial No. 495,399.
i To all whom 'it may concern.'
n the `body of the Wagon is made in two pivoted sections adapted each to be swung laterally by the pressure of the load but held normally closed by a latch; and to pivot these two sections on a common pivotal axis so that the two sections, when locked and forming the body of the wagon, shall be supported so that if the wheels of the wagon "be laterally inclined, the body will remain horizontal.
In the drawings,nFigure 1 is a side elevationv of my improved dumping wagon; Fig.
the pivotal y supported body; Fi@ 6 is a "tively the front and rear wheels of the 2 is a rear elevation of the same; Fig. 3 is a front elevation; Fig. 4 is a plan view of Fig. 1; Fi 5 is a longitudinal section of transverse ysection thereof on the line 6-6 of Fig. Fig. 7 `is a like section to Fig. 6, only showing the opposite body sections laterally swungvinidumping position; Fig. 8` is an enlarged detail axial section of the pivotal support for the body sections; Fig. 9 is an enlarged detail view of the underside of the adjacent portions of the body `sections and the latching device for holding them locked together; F iw. 10 is a side `view of the locking device; Fig. 11 is a side elevation of the foot piece for actuating the 4locking device.
In the drawings, 2 and 3 denote respecwagon. The rear wheels as shown in Fig. 2
l havethe upwardly bowed axle 4, the middle portion of which is flattened as at 5 to form a firm support for the transverse I beam 6, which is bolted to the axle 4 by clips 7. Opposed longitudinal I beams 8 are supported `on the ends of the axle 4 and held thereto by `fclips 9. The beamsS are upwardly inclined from the rear wheels as shown in Fig. 1, this inclination extending the length of the body,
and the beams then extend horizontally forward and are convergently curved, meeting at 10. They are here connected to each other by a gusset plate 11. A series of transverse holsters 12 support the forward ends of the frame formed by the beams 8 and these in turn are supported on the usual fifth wheel, 13, mounted on the axle 14. Braces 15 are attached to the upper flangesy of the inclined portions of the beams 8, extend rearward and are riveted to the flanges of the beam G. This construction it will be seen provides a reach which is elevated at its forward end and under which the wheels 2 may be turned.
Attached to the under edge of the beams 8 and extending transversely across the same at the forward end of the inclined portion thereof is the transverse beam 16, which forms the forward support for the body of the wagon. This transverse beam 16 and the transverse beam 6 form the front and rear supports on which the sectional wagon body is pivotally supported.
Referring now to Figs. 6 and 7, it will be seen that the wagon body is composed of two laterally arranged sections, 17 and 18, one section being slightly shorter than the other so as to rotate within that other into the position shown in Fig. 7, wherein the ends of one section overlap the ends of the other. The bottom of each of the two sections is formed of a downwardly and inwardly curved plate 19, the upper edge of which is reinforced by an angle iron 20. End plates 21 are riveted to the bottom plates 19 and the plates 19 are further strengthened by'an angle iron 22, which is riveted to the middle portion of each of the plates 19 and extends downward from the upper edge of the plates to the lower edge. This angle iron 22 not only reinforces the bottom plates 19 but affords a support for the locking mechanism as will be later described. The lower margins of the plates 19 are provided with longitudinally extending angle irons 23 and 24.V In the plate 19 forming the bottom of the section 18, this angle iron 23 is set back from the edge of the plate, while the angle 1ron 24 attached to the lower-most margin of the bottom plate 19 of the section 17, is attached to the extreme edge of the plate 19 and extends inwardly beyond the plate. This construction provides for an overlapping of the lowermost margins of the two sections of the CIV body as shown in Fig. 6, which prevents the accidental discharge of any material between the abutting edges of the two sections of the body. At the middle both of these angle irons 23 and 24 are provided with the alining perforations, 25, and one of the sections is formed with a locking finger 26, riveted to the angle iron 22 and adapted to extend into and through the perforations 25 of the opposed sections when the sections are closed as' in Fig. 6. i
As before stated, one of the sections of the body, as 18, is longer than the other and this body section has connected to it the projecting gudgeons, 28 and 29, while the end walls of the opposed section 17 have attached thereto outwardly projectingsleeves, 30 yand 31, which surround the gudgeons, 28 and 29, each trunnion being formed on a reinforcing member riveted o-r otherwise secured along each vertical meeting edge of the end plates. kRollers 27 are interposed between each gudgeon and sleeve, and between the sleeves and the bearing. The transverse beams 6 and 16 form a support for the pivots of the sections as shown in Fig. 8. The beam 16 supports on its u-nder side a bearing 32, which immediately supports the sleeve 30 shown in Fig. 8, and of the gudgeon course, also supports through the sleeve 30 the gudgeon 28. A washer 33 surrounds 28 and bears against the end of the sleeve 30 and against the journal bearing 32, and a washer 34 surrounds the sleeve, and bears against the bearing 32. Thus each of the sections has an independent movement-of rotation in the bearing and both sections together have acommon movement of rotation therein. The support for the rear lend 'of the body sections is practically the same as that described for the forward end. The beam 6 is formed with a bearing through which passes the sleeve 31 and the gudgeon 29 with the interposed rollers 27. Bearing blocks 35 are attached on either side ofthe web of the beam 6, and washers 36, 36a, are supported on the sleeve 31 and the gudgeon 29 and bear against either side of these blocks in precisely the same manner shown in Fig. 8. It will be seen then that the body sections are pivot- Y ally swung in these transverse beams 6 and 16, but each with a capacity for independent lateral rotative movement into the position shown in Fig. 7 vfrom their normal position shown in Fig. 6.
In order to hold the two sections of the body locked in the yposition shown in Figs. 2 and 6, I provide one of the sections with the locking linger 26, previously referred to, this finger being riveted to the outwardly extendingV flange of the angle iron 22, and
thenv bent into a` horizontal plane and eX- tended through the downwardly extending flange of the angle iron 24. This finger at its end is notched as at 38 to engage with a bolt 39 passing through the downwardly extending flange of the angle iron 22 of the opposed section. The front endof the bolt is mounted to slide in a suitable support 40 on the angle iro-n 23, and the bolt is held in its latching position by means of `a coiled spring 41 surrounding the bolt, the rear end of the spring being engaged by a pin projecting from the bolt, and the front of the spring `bearing againstthe lug 40. The end f of the bolt is formed with an `eye to which is connected a chain 42, or other flexible connection, extending forwardly and passing` over a pulley 43, suitably supportedat the forward end of the section. A pulley 44 is mounted on the transverse beam 16 over which this chain passes, the chain then eX- tending to a bell crank lever 45, formed with a foot piece, 46, and pivotally supported on one of the bolsters 12, convenient to the foot of the operator. A spring, 47, acts to return the foot piece to normal position after being` depressed.
The o eration of the invention will be obvious rom the above description.
When the wagon is loaded the two lateral sections are, of course, closed, The
locking finger 26 is inengagement with the bolt 39. This holds the lower edges ofthe' two sections together in the position shown in Figs. 2 and 6. In this position the body as a whole is pivotally supported or swung upon trunnions, which trunnions are supported in bearings on the beams 6 and 16. With this construction, the wagon vframe can tilt considerably while the body maintains a horizontal position, since the centerv of gravity is considerably below the points of pivotal connection between the body and vehicle frame. This is of great advantage in maneuvering the Awagon over rough country or in awkward positions.
When it is desired to dump thewagon, the foot piece 46 is depressed, drawing upon the chain 42, which withdraws the bolt 39 from its engagement with the latch. As soon as the bolt is withdrawn, the weight of the material contained within the body acts to rotate the sides laterally andv outwardly from each other to the position shown in Fig. 7,
thereby dumping the load. The inclination tions apart, causing the inclined'walls to separate or open, permitting the entire Vdischarge of the load,swhereupon the sections will immediately and automatically close by Y gravity and automaticallylock by reason of the spring finger.
bolt engaging Vwith the latching It is to be noted that the sides move upward when the load is dumped and that,
, therefore, there are no doors or other parts to drag in the dumped material and inter- .fere with the complete clearing of the wagon.
The weight of the sides is such that they close automatically as soon as the load has been deposited, and the locking arrangement i instead they rise, thus clearing themselves from the dumped load. "My construction provides for a wagon having great ease of travel, of relatively 'light framework, in which the center of 'ravity is much lower than in other wagons or this purpose and which can be made as short-coupled as necessity requires.
While I have shown what I believe to be the preferable and effective details of construction, I do not wish to be limited to these,
a inasmuch as they may be changed or modified in many ways, within the scope of the claims, without departing from the spirit of my invention.
Having thus described my invention, what I claim as new and desire to secure by Letn' directions to drop the load from the ters-Patent, is:
