DUMPING-WAGON.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed March so, 1907. Serial No. 365,476

" wagons, and the principal objectof the invention is to provide mechanism for crating the hinged bottom sections so that t 1e load may be rapidly or slowly dropped, and thereafter the said hinged bottom sections may be quickly returned to their closed position.

A further object resides in the arrangement and location of the operating mechanism whereby it will be in a position to be readily manipulated by a person upon the drivers seat of the vehicle, with the use of but one hand.

A furtherobj ect resides in the arrangement of the operating mechanism whereby the opening and closing movements of the hinged bottom sections is controlled and regulated by means of one lever.

A further object is to provide means whereby the bottom sections will be caused to close one in advance of the other.

A fu rther object is to provide a safety looking means for the o eratmg mechanism which w' I normally hol the said operating mechanism in its locked position, but which can be readily disengaged therefrom when desired.

A still further object is to provide an improved form of hinge connection for the bottom sections that will cause them to swing clear of thesides of the wagon body, when they are in their lowered, or open osition, so that they will be out of the path of the material being dropped.

Other and further objects and advantages of the invention will be apparent from the following detailed description when taken in connection with the accompanying drawings.

Of the accompanying drawings, in which like gcharacters of reference refer. to corre-' sponding partsFigure 1 is a longitudinal sectiona view through a dumping wagon, showing the arrangement of the ift ing chain.

' Fig. 2 is afront view of the mechanism for opcrating the lifting chain. Fig. 3 is side view of the operating mechanism the same being shown in its operative position in full lines and in its inoperative position in dotted lines.

Fig. 4 is an end View of the wagon, the bottom sections being shown partly lowered. Figs. 5 and 6 are details of the hinge connection between the sideboards of the vehicle and the bottom sections. Fig. 7 is a detail sectional view of one of the hollow sills of the bottom sections;

In the annexed drawings I have illustrated a conventional form of wagon body, the sides of which are extended forwardly and are provided with bearings 10 for the drum, 11.

. As is shown more clearly in Fig. 2 of the drawings, this drum 11 extends entirely across the wagon, and is located below and forward of the drivers seat. An enlarged worm or thread 12 is mounted upon one ortion of the drum 11, preferably the left and portion and is held relatively immovably thereto by means of bolts, or other securin means' 1314 designate respective y the right and left bottom sections which are hinged at their outer edges to the sides of the wagon body. One of these bottom sections (14) is provided with an extended portion 15, that forms an overlap for the opening formed by the meeting edges of the two sections; The under faces of the two hingedbottom sections are each providedwith ahollow sill 1 6-1 6 that extends the entire length of each section and is located at their meeting edges. Within the upper portion of each of the sills 16-16,

and at each end thereof, are located.

Centrally .located upon the rear face of the back of the wagon body are two pulleys The pulley 19 is mounted to freely rotate upon its pivot, and the pulley 18 is so mounted that there is a resistance to its rotation. Any preferable meansmay be used to cause this resistance to the rotation of the pulley 18, the simplest being the present structure in which the resistance is caused by the increase in the size of its ivot.

20 designates a chain one end of which is securely attached to the right hand side of the drum 11, and has a few turns wound upon that portion of the drum. The loose ,portion of the chain is then passed over a pulleys or rollers 17 i ,mounted in theend of'the loop imity to the ratchet or pinion 21.

enlarged worm or thread '12, after which its end is securely attached to the drum adjacent to or upon the said worm or thread.

A ratchet or pinion 21 is rigidly mounted uplon the drum 11, at the extreme right hand s1 e.

22 designates an elongated lever, the lower portion 0 which is bifurcated to provide the arms 23 23, and these arms terminate in the circular portions 24 24, which are of a size sufficient indiameter to permit of the drum 11 being readily passed therethrough.

25 designates a pawl that is pivoted within'the upper part of the bifurcated portion of the lever 22. A rod 26 has its lower end in pivotal engagement with the pawl 25, and its upper end is in pivotal engagement with a hand lever 27 which is in turn pivotally connected with the 11 per end of the lever 22.

28 designates a ever that is located to the left of lever 22, and this lever 28 extends forward adjacent to the bifurcated portion of said lever 22. The lower end is bent around the circular portion 24 one of the bifurcated arms of lever 22, and then extends forward a short distance, and is then bent around to form a loop portion 29, that terminates directly in front of the ratchet or pinion 21.

30 designates a bracket that extends from the side of the wagon body, and has its end bent around the side-of the loop 29.

through the end of bracket 30, and the loop 29, and has bearing in the side of the wagon body.

32 designates a pawl that is pivotally 29, in prox- 33 designates a locking 'aw or hook that is pivoted to one side of I t e lever 28. The curved lower portion of this hook or jaw is of substantially, the same contour as the drum 11, and is so located upon the lever 28 that when it is dro ped down, its hook portion will engage wit 1 the drum 11.

The relative arrangement and location of the parts just described is best shown in Figs. 2 and 3 of the-drawings, and by reference to said figures it will be seen that the bifurcated portion of lever 22, extends down upon both sides of the ratchet or pinion 21, and that the circular end portions through which the drum passes rests against the ends of the hubs of the said ratchet or 'inion. The pawl 25 which is mounted in t e bifurcated portion is so arranged that its ratchet-engaging end extends rearwardly and when in engagement with, the ratchet or pinion, such engage ment is with the rear portion, which prevents the said ratchet or pmionfrom rotating forwardly. The pawl 32 that is mounted in the 100 29 of lever 28, has its ratchet-engaging en so arran ed that it extends rearwardly, and is norma y in engagement with the front of the ratchet or pinion, which also prevents tion is slightly concaved to form a seat 31 designates a pivot bolt that extends said ratchet or pinion from rotating forwardly, or in a direction to cause the opening of the bottom sections.

In dumping wagons of this general type, one disadvantage has resided in the fact that when the hinged bottom sections are in their dropped or open position, they do not swing far enough outside of the line of the side boards of the wagon body, the result being that there are projecting edges left in the path of the material bein dro ped, and as such edges catch a consi erab e amount of the material, difliculty is caused when it is attempted to return the bottom sections to their closed position. viating this objection, I have designed the form of hinge connection shown more clearly in Figs. 4, 5 and 6 of the drawings, in which 34 designates metal straps that are secured to the under sides of the bottom sections. These straps extend to the outer edges of the bottom sections, and their end portions are bent first at right an les to form a short upward extension, and t e end of this extension is then bent over u on itself to form an eye 35. The side boar s are each provided with vertically arranged metal straps 36, the lower ends of which are each rovided with the enlarged portion 37, provided with an opening. Preferably the periphery of this enlarged fporor a U-bolt 370, that forms an additional securing means for the straps 36 and also forms a strengthening means for the enlarged ortions 37. In assembling the hinges the olt or intle is placed within the eye 35 with its en s projecting from each 'side thereof. The side straps 36 are then placed in position so that the ends of the bolt orpintle will be within the openingsor recesses in said enlarged portions, after Whichsaid; side straps are secured in position on the side boards of the wagon body.

The operation of the invention is as follows :Assuming the wagon to be in its closed position, and that it is desired to open the bottom sections.The locking jaw 33 is turned upon its ivot, freeing it from engagement with the rum 11. Lever 28 is then free to be thrown forward. Such forward movement of lever 28 released pawl 32 from its engagement with the ratchet or pinion 21. The pawl 25, by means of its rod and hand lever enga ement with lever22, is then thrown out of engagement with the ratchet or pinion 21, the drum 11 is then free to revolve. The weight of the load causes the hinged bottom sections to drop which of With a view of ob-' course carries with them the chain 20 that is position. When such bottom sections are teeth thereof, the degree of pressure, or resistance, afforded by said pawl being regulated by the amount of pressure exerted upon the hand lever 27.

l/Vhen it is desired to close the bottom sections, lever 28 is thrown back to its rear position, and the locking 33 is turned upon its pivot and allowed to fall to its lowered position where its curved end engages with drum 11. The locking pawl 32 having been brought into engagement by the backward movement of lever 28, the said pawl is in position to prevent a forward rotation of the ratchet or pinion, or a rotation that would permit of further opening of the hinged bottom sections. As thev lower ends of the bifurcated portion of lever 22 are loosely mounted on the drum 11, such lever can be moved backward and forward relatively to said drunn Lever 22 is then rocked forwardly and rearwardly, the forward move-' ment causing the pawl 25 to click.along the ratchet or pinion 21, the rearward movement causing the pawl to engage with and rotate said ratchet or pinion. The rotation of the ratchet or pinion imparts its rotations to the drum 11. As the ends of the chain 20 ane attached to different portions of the drum 21, and such different portions of the drum are of different diameters, it will be readily understood that the chain is wound upon the drum at different speedsthat is, the end secured to the larger portion of the drum is Wound faster than the ortion of the chain which is wound upon t e portion of the drum that is of a small diameter. It

.will also be understood that when the bottom sections are in their opened or lowered position the chain will be hanging ractically oosethat is, there will be no pu ling pressure upon it. And it will be further understood that when the chain is in such loose position, it will practically form two long loops-one extendin down the right side of the; wagon from the front pulley a down and through. the sill and up ]819 at the rear of the wagon body. The other loop extends from the pulle s 1819 down into and through the sill 16 at t e left side of the wagon body then up to the pulley bat the frontof the wagon body. As the drum 11 is rotated to wind the chain 20 thereon, the first or initial lifting movement will be to the two pulleys imparted to the left hand loop, for the reason that, as the chain is practically loose inboth loops, the first movement of the chain is one that will ti hten it, and when the chain is tightened, tIiere is a slight resistance to the further movement of the right loop caused by the retarding action of friction pulley 18,

such retarding action, while being slight, is

sufficient to enable the left loop to have started the lifting movement of section 14, and as the retarding action of the pulley 18 is continuous, and as the left loop is being drawn faster than the right loop on account of its being wound upon the enlarged portion of the drum 1 1, the result is that the bottom section 14 is closed in advance of the bottom section 13. And as bottom section 14 carries the overlapping portion 15, it will be in position to cover the opening formed by the meeting edges of the two sections.

From the foregoing description it is thought the objects and advantages of the invention will be a parent. It will be understood that while I liave described the locking jaw 33 as a means for retaining the lever further function of providing an eiiieient means for retaining such lockingleverm position when the wagon is traveling, it being of especial advantage as when the wagon is traveling over rough roads where there is a liability of the levers being jolted out of position. It will also be understood that any suitable means may be provided to prevent the chain from being displaced from its carrying pulleys. For example, I have provided the sill pulleys with a loop through which the chain passes, and have provided the rear pulleys with a sheath or covering,

and have mounted the front pulleys in brackets. I

Throughout the specification and in the drawings I have set forth the lifting means as an endless chain. This has been done for convenience and as the preferred form, but I wish it to be understood that I do not desire to limit myself to a chain, for it will be obvious that any other form of cable possessing the necessary strength may be substitheir free edges each provided'with a hollow sill, one of said sills being provided with an overlapping portion, a chain having portions passed througheach sill, a drum to which said chain is secured, and meansfor retarding the movement of said sections, said sections being mounted to swing beyond the plane of the said body when in dumping position.

3. A dumping wagon comprising a body, dumping sections hinged thereto, a drum connected with said sections, a ratchet on said drum, a lever for rotating the same, a locking lever having a pawl engaging said ratchet, and a locking member depending from said locking lever and normally engaging said drum.

4. A dumping wagon comprising a body, dumping sections hinged thereto, a drum connected with said sections, a ratchet on said drum, a lever for rotating the same, a locking lever having, a pawl engaging said ratchet,

and a locking member depending from said locking lever and provided with a curved portion normally embracing the lower face of said drum.

5. A "dumping wagon comprising a body, dumping sections hinged thereto, adrum connected with said sections, a bifurcated ratchet lever mounted on said drum, a ratchet and embracing the lower face of said drum.-
