ASPECI]5IC.A'1IO1\T forming part of Letters Patent No. 748,075, dated December 29, 1903- Applieation led July 23, 1903.

To a/ZZ whom it may con/cern: i

Be itknown that I,JOHNT.HOPE,a citizen of. the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Dumping-Wagons; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings,forming a part of this specification.

'Ihe objects of my invention are, first, a wagon box or body the bottom of which is convertible into self-dumping parts; second, to enable the dumping parts to form a continuous bottom when in a closed position without leakage of the contents of the wagonbox; third, to divide and dump the loose contents of a wagon-box from either end of the box at the will of the driver when the vehicle is in movement or stationary; fourth, to enable thedumping parts of the bottom to be tilted upwardly by the dumped material and avoid dragging the material in the line of direction of the moving wagon; fifth, to accelerate the movement of material gravitated by the du mpiug parts of the wagon-body; sixth, to effect the raising in position of separate parts of the dumping-bottom simultaneously; seventh, to enable the tilting part or parts of the bottom of the wagon when raised to its normal position to self-lock; eighth, to disassociate the running-gear for dumping-wagons and reinforce the parts; ninth, to shift initially the weight upon the dumping-bottom past its center of gravity; tenth, totake up the slack in the hoisting-chains for separate dumping parts of the bottom equally.

The invention consists in the novel construction and combination of parts, such as will be first fullydescribed, and specifically pointed ou'tin the claims.

In the drawings, Figure 1 is a View in perspective of the novel dumping-wagon, showing the dumping parts of the bottom in an open discharging position with the intermediate division board of the wagon-box removed. Fig. 2 is a plan view of the wagon, showing the dumping parts of the bottom in a closed position and the division-board in place; Fig. 3 is a longitudinal sectional View Serial No. 167,256. (No modali:

of the dumping-wagon,taken on the line 7 7 of Fig. 2, showing the position of the du mp- `ing parts of the bottom in a closed position and in dotted lines their position when'discharging the contents of the wagon-box, also showing the lever for initially shifting the weight on the forward dumping part of the wagon-box. Fig. 4 is a transverse vertical sectional view taken on the line 8 8 of Fig. 3. Fig. 5 is a detail broken view of the chainwinding shaft on the forward i end of the wagon box, showing one of the windingspools. Fig. 6 is a detail sectional View of the side of the wagon and a portion of the rear end of the rear tilting bottom and the hook connected with the hoisting chains. Fig. 7 is a detail View of the adjustable de- `vices for taking up the slack in the hoistingchains.

VSimilar numerals of reference indicate corresponding parts in all the figures of the drawings.

Referring to the drawings, 10 10 represent the longitudinal vertical sides, and 12 the forward vertical end, of the wagon-box, which are rigidlylconnected together, the forward end of said sides projecting a short distance forwardly of the line of said end. 'lhe lower edge of said end is flush with the horizontal line of the lower edges of said sides 10 1U. The rear end 13 of the wagon-box is the same width as the sides 10 10 and is arranged in the grooves 14 14 on the inner surface of the sides 10 10 at a point a short distance forward of the rear ends of said sides, which grooves incline rearwardly and at an angle to said sides.

Beneath and supporting the sides and forward end of thewagon-box a short distance in rear of said end is a wagoubolster 15. With each end of said bolster are secured the wagon-stakes 16 16. Beneath the bolster 15 is the forward axle 17 of the wagon, which is of the usual construction and in separate longitudinal parts and slotted transversely at 18 18 to receive the inner ends of the hounds 19 and at 20* to receive the forward end of the coupling pole or bar 20, to the forward and rear axles upon which bar or pole the curved rear end 19 of the hounds obtains the usual.

frictional bearing. The bolster 15 under the wagon-box is secured pivotally to the axle 17 ICO by the king-bolt, (see Fig. 2,) which passes through the said bolsterintermediate its ends and through the forward end of the couplingbar 2O and the axle. Extending transversely to and beneath the forward end of the wagonbox a considerable distance in rear of the bolster 15 is a bar 21, and with the ends of said bars are connected the plates 22, which extend upwardly on the outer surfaces of the sides 10 10 of the wagon-box and are secured thereto by screw-bolts 22X. In order to provide clearance for the downward movement of the rear end of the forward tilting part of the bottom of the wagon-box, the coupling pole or bar 2U is broken away at a point a short distance rearwardly of the curved rear end 19 of the hounds, and to maintain its rigidity a strap 23 is secured ata point intermediate its length to the rear end and under side of the portion of the pole or bar 20 connected with the axle, and the outer ends of said strap are extended upwardly and in the direction of the sides 10 10 of the wagon-box and secured to the under side and ends of the bar 21.` A brace-bar 25 is connected at one end rigidly with the upper surface and rear end of the transverse bar 21 above the connection of the strap 23 and the forward end of said bar extended between the bolster 15 and axle through which the king-bolt passes, thus aording a strong connection of the wagon-box with the axle.

Upon the axle 17 are the forward wagon` wheels 26 26. With the forward ends of the hounds 20, which extend through the axle 17 and a short distance beyond the forward side thereof, is pivotally connected at 27 the forked ends of the draft-pole 28. The sides 10 10 of the wagon-box are mounted directly upon the rear axle 29 of the wagon, which axle is located the usual distance in rear of the forward axle, upon which rear axle are the rear wagon-wheels 30 30. With the under side and each end of axle 29 and near the hubs of the wheels 30 are secured rigidly the reinforcing-straps 31, the separate ends of each strap being twisted outwardly and extended in opposite directions and at opposite angles of inclination upwardly and connected rigidly with the outer surfaces of the sides 10 10 of the wagon-box by suitable screws or bolts 32.

The bottom of the wagon-box consists of a separate forward tilting or discharging part or platform 33 and a rear separate tilting or discharging part or platform 34, each part of the bottom extending from the inner surface of one side 10 to the inner surface of the other side, the under surfaces of said parts in a closed position being within the lower edges of the sides 10 10. The forward end of the tilting part 33 of the bottom extends from a position nearly in contact with the inner surface of the forward end 12 of the wagon-box and is supported by the bolster 15 on the axle and the running-gear, and its rear end extends to a position a short distance in rear of a point intermediate the forward and rear ends of said wagon-box. Supporting pivotally said part or platform 33 of the bottom is a transverse beam 35, secured rigidly to the under side of the platform directly above the hounds of the axle and at a point on said platform or part of the bottom less than onehalf the distance from the forward to the rear end, so that the center of gravity of a load on the said tilting part of the bottom may be located in rear of its support.

The transverse beam 35 is mounted upon the radins of a transverse rock-shaft 36, a groove 37 in the under side of the beam admitting the upper part of the shaft with which it is. parallel, as seen in Fig. 3, the shaft being connected with the under side of the beam rigidly, so as to rock withthe shaft by means of the bolts 38.` The ends of the rockshaft 36 extend toa position beyond the vertical lines of the outer surfaces of the sides of the wagon-box and are journaled in the lower perforate ends of the plates or shafthangers 39 39 on each side of the wagon-box, the upper ends of which plates are secured vertically in position to the outer surfaces of the sides 10 10 at a point a slight distance in rear of the ends 23 23 of thestraps securing the bar 2O above the hounds. The rear part 34 of the bottom is supported in a like inanner as described of the forward part 33 by means of a transverse beam 40, secured transversely to the under side of the platform 34, said beam being located in rear of the rear axle 39 and mounted on and secured to a rock-shaft 41, journaled at each end in the perforate lower ends of the plates or shafthangers 42, which are secured to the outer surfaces of the sides 10 10 of the wagon-box by the bolts or screws 43. The forward end of the platform 34 is supported by the rear axle 29 of the running-gear.

Upon the under side and rear end of the forward tilting platform is secured rigidly a transverse cleat 44, a portion of which cleat extends beyond the said end of the platform beneath the forward end of the rear part 34 of the bottom and closes the joint when the parts are in line with each other.

The tilted parts of the bottom are controlled as follows: Through the sides 10 10 of the wagon-box and the portion of said sides projecting beyond the forward end 12 extends a transverse shaft 45, which is located a short distance below the line of the upper edges of said sides. Upon each end of the shaft projecting beyond the outersurfaces of the sides is a spool46, upon the circumference ofwhich spool is a spiral groove 47, extending the length ofthe spool. (See Fig. 5.) Upon the outer surfaces of the sides 1010 of the wagonbox, near the upper edges and rear ends, are secured the pulley-blocks 48 48. At a point on the sides 10 10 of the wagon, about equidistant from the blocks 48 and the forward end of the wagon-box, are connected the pulley-blocks 49 49, which are located in position an increased distance downwardly from ICO the upper edgef of the sides 10 10 than the Y `blocks 48.

With one end of the spools 46 46 and in the groove 47 are connected the inner ends of hoisting-chains 50 50, the other ends of which chains extend to the rear end of the wagonbox and over the pulley in the pulley-blocks 48 48, thence downwardly and connected with the hooks 51 51, located near the rear end and outer longitudinal edges of the rear part 34 of the tilting bottom, the lower ends of which hooks are connected with the outwardly-extended ends of the bars 52 52, which are secured to the underside of the partor platform 34 by the bolts 53 53, as seen in Fig. 6, so that when the part 34 of the bottom is in a closed position `there is considerable space between the hooks 51 51 and the outer surfaces of the sides 10 10. With the chains 50 50 at a point a considerable distance from their inner ends are connected the inner ends of separating hoisting-chains 54 54, the outer ends of which chains extend over the pulleys in the pulley-.blocks 49 49, thence downwardly and connected with the vertical hooks 55 55, secured to the outer projecting ends of bars similar to bars 52 andwhich are connectedr with the under side of the cleat 44 on the for-` ward tilting end of the separate part 33 of the bottom in like manner as described of the hooks 51 51. `To the `outer surfaces of the sides 10 10 of the wagon-box are secured pivotally and directly above the outer ends of the bars 52 52 the self-engaging catches 57 57.

These catches are centrally pivoted to the` wagon-box and are in the form of the letter S, the upper portion being cast heavier or Weightier than the lower portion 56, said lower portion being curvedrin the arc of a circle and engages with the outer ends of the bars 52 52 when the part 34 of the bottom is in a closed position, the upper end of the catch serving to throw the hooked portion of the catch beneath the bar. Upon the side 10 of the box is a pin 57X, which holds the catch when inverted in position. Similar catches are connected with the sides of the Wagon -box, which engage with the bars on the cleat 44 on the forward end of the tilting part 34 of the bottom. On one side of shaft 45, between the spool 46 and the side 10 of the wagon-box, is a ratchetwheel 59, and on the side ofthe box is a pawl 60,lengaging with the wheel. (See Fig. 2.)

`Upon the other end ot the shaft outside of the spool 46 is a hand-wheel 61, and upon said wheel is a handle 62.

Upon the inner surfaces of the sides 10 l0 at a point intermediate the ends 12 and 13 of the wagon-box are vertical guide strips or cleats 63 63, which serve to retain a divisionboard 67, as shown in full lines in Fig. 2, and dividing the box into separate parts transversely, when required, the lower edge of which board 67 rests upon the rear end of the forward tilting part 33 of the bottom when the said part is in a horizontal or closed position. A

In each chain 50 and 54 at a convenient point in its length is inserted an adjustinglink 64, having swivel connection 65, and a screw 66, extending within a perforate end of the'link, as seen in Fig. 7, which are respectively connected with detached links, so that a slight adjustment may be made in the length of the chain` to a lesser degree than the length of a single link.

The tilting points 33 and 34 of the bottom being in the position as seen in Fig. 1, in which the contents of the wagon-box are fully dischargd upon the ground, power is applied to the wheel 61 through the arm 62, and shaft 45 is rotated, the hoisting-chains 50 and 54, communicating an equable draft to the respective rear ends of the parts 33 and 34 of the bottom, the chains winding upon the spools 46 in the grooves 47, so that the take-up is equally proportioned. Thelength of the separate chains 50 and 54 and the parts of the bottom are drawn into a horizontal position, as seen in Figs. 2 and 3, making close contact with the sides of the wagon-box and forming a continuous bottom, the lower end 5S of the catch 57 engaging automatically with the bar 52, the wagon-box being suitable for the transportation of grain or fine substances, as soil, without sifting through the bottom or unnecessary waste. The catches 57 on the sides of the wagon-box may be vcanted y over upon the pins57 so as to beout of en gagement with the ends of the bars 52, supporting the hooks 51 and 55, and in this position the ratchet-wheels 59 are held bythe pawl 60 when the vparts 33 and 34 of the bottom are hoisted into a closed position. Should, however, it be desired to transport different kinds of articles or cereals or dierent kinds of coals, the division-board 67 is inserted between the cleats or strips 63, the catches thrown into engagement with the ends of the bars 52, and the wagon loaded with the various articles. By the disengagement of the catches from the bars it is readily seen that the contents of the rear end of the wagon-box may be discharged prior to the other end, or vice versa, thus enabling separate deliveries of separate commodities, or` fall from the wagon without confusion or intermixing.

With the division -board removed the wagon-box is adapted for the transportation of loose material in bulk,such as corn or grain, and when it is desired to discharge the contents of the wagon the pawl 60 is disengaged from the ratchet-wheel and the center of gravity of the load being toward the rearends of the parts 33 and 34 of the bottom a slack in the chains 50 and 54 is sufficient to tilt the parts downward and eect the discharge, it

IIC

being observed that the position of the beams parts of the bottom downwardly. In the breaking up of the compact body of the material in the wagon -box anterior its final discharge the respective forward and rear ends of the separate parts 33 and 34 of the bottom move away from each other, and the resistance to this movement becomes less when the rst movement downward of the tilting part 33 occurs, and this start given the contents of the box is immediately discharged. Frequently the portion of the load imposed upon the forward part 33 of the bottom may be heaviest adjacent to the forward end of the wagon-box and compact, so that to overcome the gravity of the material and cause a movement upwardly so far as to expose'the opening an initial movement of the forward end of the part 33 may be necessary. To effect this result, upon the lower edge of the forward end l2 of the wagon-box is a footoperated lever 68, which is pivotally connected at a point midway its length to a bearing 69, the outer end of the lever being extended forwardly and curved upwardly in a slight degree and the rear end curved upwardly and made to contact with the under surface and forward end of the part 33 of the bottom, so that downward pressure of the foot will give the initial movement upwardly, so as to shift the load.

In the application of my invention to a wagon in which fifth wheels are employed the beam supporting the wagon-box is secured rigidly to the upper portion of the fth-wheel, and I may use a number of beams upon the under side of the wagon-box the same as beam 21 and upon each side of said beam. y

The rear ends 13 of the wagon-box maybe withdrawn from the sides at any time the Wagon-box is required'for the purpose of carrying lumber or for expressage, and thus adapting the wagon for all uses required of a wagon. The tilting bottom may be applied to a two-Wheel cart or to railway-cars or to vehicles when required and operated as heretofore described, it being observed that the weight of the load in the Wagon-box is sustained to a considerable extent by the axles and running-gear of the wagon instead of throwing the jar wholly upon the sides of the wagon-box.

Such modifications of my invention may be employed as are within the scope of the invention. i
