DUMPlNG- WAGON.

Specification of Letters Patent,

Patented April 30, 1907.

Application filed October 5, 1906. Serial No. 837,606.

To LLZZ whom it may concern: Be it known that I, WILLIAM T. GABRI- SON, a-citizen 0f-the United States, residing at Columbia, in the county of Lancaster and following is a specification.

This invention relates to dumping wagons, and more especially to that class of wagons in whiohhinged bottom gates or leaves are used.

The principal object of the invention is to provide an improved means for effecting the closing movement of the gates, so that the edges of the same may overlap, .one of the gates closing slightly in advance of the other.

A further object of the invention is to so arrange the gate closing mechanism that thegates will be firmly.v and securely held and a perfectly tightjoint formed between them.

A still further object of the invention is to provide an improved form of lever on which the rear end or bight of the gate closing chain may be secured, and which will operate to effect the closing of the gates one after the other.

A still further object of the invention is to provide a connecting bar of such nature that one of the gates will be moved to closed position in advance of the other, the order in which the gates close being determined by the resistance .which they offer to the closing movement, so that the left hand gate may close first at one time, while the right hand gate may close first the next time.

A still further object of the invention is to provide an improved chain guiding means which will permit free' movement of the chains with minimum friction.

A still further object of the invention is to- 1 will more fully hereinafter appear, the inven tion consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form,

proportions, size and minor details of. the

structure may be made without departing from the spirit or sacrificing any of the" ad-.

vantages o? the invention.

In the accompanying drawings :Figure 1 is a perspective view of the rear end of the body of a wagon constructed in accordance with the'invention. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is a transverse sectional view through the body of the wagon, showing the bottom gates in closed position and showing, also, the open position in dotted lines. Fig. 4 is an enlarged detail view of a portion of the structure shown in Fig. 2. Fig. 5 is a sectional elevation of the lever or connecting bar showing the manner in which the chain is attached. Fig. 6 is a detail perspective view of the bar detached. Fig. 7 is a plan view of one of the forward chain guides detached. Fig. 8 is a rear elevation of the same.

Similar numerals of reference are employed to indicate correspondim parts throughout the several figures of the rawings.

The body of'the wagon is-mounted on suitable supporting wheels, the rear wheels beingdisposed at the ends of an axle bed 10, formed of wood, the lower face of the axle having a longitudinally disposed recess in which is placed a reinforcing bar 11 formed of iron or steel, the bar bein of less width than the axle for a purpose hereinafter described.

The sides 15, the front 16, and the rear wall 17 of the body may be of any ordinary construction and formed of any suitable material.

Secured to the outer faces of the side walls 15 are straps 17, the lower ends of which are provided with eyes for the passage of a pair of pivot-bolts 18tl1at extend for practically the full len th of the gates, and on the gates are secured similar straps 20, also having eyes for the reception of the pivot bolts, the

pivotal connections being preferably so arranged that when the gates are in open position there will be little or no gap between the gates and the sides 15.

The rear ends of the gates are arranged to fitsnugly against the forward face. of the axle bed, as will be evident on reference to Fig. 2, the joint formed being sufliciently close to prevent the passage of fine articles of the load from'the receptacle. ends of the gates are provided withguard flanges 23 which preferably are formed of angle bar, the upper webs of these bars bein disposed on lines paral e1 with the front wall of the receptacle, and eing designed'to fit snugly against the outer face of the front T e front.

wall in order'to prevent the escape of particles of the load, and at the same time to avoid endwise movement of the gates while the wagon is moving. Secured to, and extend-v ing longitudinally of each of the gates is a bar 25 that is arranged nearthe front edge of the gate, each bar being provided at its rear end with a recess in order that it may properly with a pivot pin f runs of the chain thence chain bears during the wise secured to the fit against the axle, and extending from the ends of these barsare chain guiding eyes 26, the inner walls of which are rounded in order to permit free play of the gate closing chains 27. Near the central portion of each of the bars 25 is a small hanger .or bracket 29 carrying a sheave or roller 30, against which the gate closing operation, so that force will be exerted at both ends and at the center of each gate in order to hold the same tightly closed.

.Secured to the upper central portion of the axle 10 are two straps 30 and'31, the base portions of which are secured to the axle by bolts 82,'the bolt openings being arranged beyond the edges of the metallic reinforcing bar 1 1 of the axle. The outer strap or bracket 30 is extended up and is bolted or otherrear wall of the receptacle. or brackets are provided r the reception of a connectinglever 33, the pivotpoint of which is arranged to one side of the center so as to form two arms ofunequal length. The up- These two straps per face of the lever is arranged to engage y with the chain 27 the lever being preferab recessed, so that the links of the seat therein, and securing bolts 36 being employed in order to prevent any independent movement'of the chain. The two runs of the ain xt n t gh t id n e -2 and engage with the sheaves or rollers 30, and at the front of the wagon are extended upward and pass through a guide 38 that is firmly secured to the front wall 16, the two passing to a suitable winding drum 39. The ide 38 is prefer- .ably in the form of a U-S. @Ped bar'of suflicient width to permit the free passage of the chain, and the inner wall of this bar is rounded, so that the chain is free to ride thereover, and to accommodate itself to the Winding operation as the. chain is coiled around the drum. a

That run of the chain which extends from the shorter arm'of the connecting .lever 35. is a trifle shorter than the other run of the chain, and this insures perfectlapping of the and the formation of a tight joint between them to prevent the escape of gates or doors,

the load.

The gate which closes first being the gate which is connected by the chain to.- the shorter arm of the lever, is provided with a pre ewns l p r fl ge 0 formed of'sheet m l, d e t r ate TS-ar anged t -fit ainst is r or fl n e a e the fir sate chain may,

lever 35, but owing to the difference in'the length of the arms, the longer arm will de scend while the short arm is raised, andthe gate to which this shorter arm is connectedwill, therefore, be moved to closed position in advance of the other. After the first; gate reaclies the closed position with the connecting lever still at an angle to the horizontal, the continued movement of the chains will draw the second door or gate closed, and as that run of the chain connected tothe shorter arm is of less length than the other, the force of both chains will be employed in closing the second gateand the lever will be pulled from its inclined position to an approximately horizontal position during the latter portion of the gate closing operation, the force exerted at this point being sufificientjo filrnly hold the gates closed "anClI make a tight oint between them.

It will be noted that the construction-of the lever is such that there can be no possibility of said lever sition, or to such I the matter of closing of the gate a matterof uncertainty. In all cases the gate connected. to the shorter arm of the lever must first move to closed position, and it is not neces sary to employ any auxiliary stops or other moving to inoperative poj pos tlon as would render devices for limiting movement of'the lever in either direction.
