VICTOR D. JOHNSON, OF AURORA, ILLINOIS.

MATERIAL CONTAINING AND IDEPOSITING DEVICE.

To all whom it may concern:

Be it known that I, VICTOR D. JOHNSON, a citizen of the United States, residing at Aurora, in the county of Kane and State Of Illinois, have invented new and useful Improvements in Material Containing and Depositing Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention pertains to material containing and depositing devices, and relates particularly to dump wagons. Such devices, and especially dump wagons, are usually subject to the disadvantage that considerable space must be left between the bottom of the material container and the surface upon which the material is to be deposited; and it is one of the objects of my invention to produce a material containing and depositing device which will not have this disadvantage, z'. e., to produce a device in which the bottom of the container may be located near the surface upon which the material is to be deposited.

It is another object of my invention to produce a device which may be used without danger to the operator. And it is a further object of my invention generally to improve upon devices of the character set forth above.

A dump wagon constructed in accordance with my invention is shown in the accompanying drawings and described in the following specification.

I have shown and described this device in order that my invention may be clearly understood; but changes may be made in the device shown without exceeding the scope of the appended claims, and the invention may be embodied in other constructions within the scope of such claims.

In the drawings :F igure 1 is a plan of the wagon frame and body; Fig. 2 is an end view of the same, showing the portions of the body together, a part of the frame being broken away to show the dumping mechanism; Fig. 8 is a view similar to Fig. 2, but

" 1 showing the portions of the body in the position they assume after the dumping mechanism has been partly actuated; Fig. 4 is a view similar to Fig. 3, but showing the portions of the body in the position which they assume after the actuating of the dumping mechanism has been completed; and Fig. 5

Specification of Letters Patent.

Application filed, July 21, 1911.

Patented Sept. 24, 1912. Serial No. 639,775.

is an end view showing the portions of the body in the widely separated position to which they may be moved by the load itself in escaping from the body.

In the particular embodiment of my in vention which is shown in the drawings, the wagon frame is rectangular and consists of two side bars and two end bars 11, these bars being formed of channel iron and being secured at their ends by means of rivets or the like. Connected between the side bars 10, but below the level of the same, are two transverse track bars 12, also formed of channel iron, which are secured in place by hangers 13 riveted to them and to the side bars 10.

The track bars serve to support the body 14: of the wagon, which body is of semicylindrical shape and divided centrally into two portions which are adapted to be separated when the contents of the body are to be dumped. In being separated from each other, the portions of the body first move transversely away from each other, thereby loosening the load, and then tilt in Opposite directions, whereby the load is dumped. To this end, the body 1 1 is provided with four brackets 15, one at each end of each portion of the body; and in these brackets are jour naled rollers 16, which engage the top surfaces of the track bars 12 and are adapted to roll thereon. The portions of the body 14 are provided, at the meeting edges of their ends, with overlapping horizontal arms 17 having in their ends short slots 18. Through these slots 18 pass bolts 19 which are vertically guided in vertical slots 2) formed in standards 21 which extend upward from the track bars 12. These parts constitute a lost motion connection between the two body portions and the vertical guideway. Considering the portions of the body as being in the positions shown in Fig. 2, it will be seen that, if a force tending to separate these portions be exerted upon them at the brackets 15, the body portions will move transversely away from each other on the rollers 16. When, however, they have separated to such an extent that the ends of the slots 18 in the arms 17 engage the bolts 19 Fig. 3), the portions of the body can only move farther by tilting about the bolts 19, which bolts descend in the slots 20. It will be seen, therefore, that the portions of the body first separate transversely, and then tilt about the rollers 16 as pivots, these rollers continuing their transverse separating movement. Thus, during the latter portion of the move ment of the portions of the body, the portions simultaneously tilt about the rollers 16 and slide upon these rollers. This combined movement is very advantageous, in that the portions of the body have not, in separating, any tendency to compress the load and thus be hindered in their operation. In fact even if the device were not constructed so that the body portions had the preliminary trans verse movement described above, these portions would still move laterally away from the load while opening benr i it,--thus facilitating the dumping opeia...on.

The mechanism for effecting the tilting operation is substantially the same at each end of the wagon, and a description of that at one end, therefore, will suffice. Mounted in bearings 22 carried by the track bar 12 and the end bar 11 of the frame, is a spindle 23 which carries at the end thereof, adjacent the body 14, a cross head 24, which is normally disposed in a horizontal plane, as shown in Fig. 2. Arms are pivotally connected between the ends of the cross head 24 and the brackets 15 carried by the separable portions of the body 14, each arm 25 being connected to that end of the cross head 24 which extends away from the bracket 15 to which such arm is connected. The points of connection of the arms 25 t'with the brackets 15 are substantially in the same plane as the points of connection of these arms with the cross head 24; so that the arms 25 are in a dead center position when the parts are in the condition shown in Fig. 2. It will be seen that, if the spindle 23 be rocked in a clockwise direction, the arms 24 will exert a force upon the brackets 15 tending to separate the portions of the body 14, and will therefore first move them apart and then tilt them. It is to be noted, however, that this movement of the portions of the body can only be effected by rocking the spindle 23; since, unless the spindle is rocked, the body portions are securely locked against movement, owing to the fact that the arms 25 are in a dead center position when the body is closed.

The spindle 23 carries, between the bearings 22, a lever 26, to the outer end of which is connected one end of a link 27. The other end of the link 27 is connected to a curved lever 28 carried by a rockable shaft 29, the

latter being mounted in suitable bearings so as to extend longitudinally along one side of the wagon frame. The link 27 is provided with spaced stops 30 and 31, adapted to be engaged by the forked end of an operating lever 32 which is rockably mounted in a bearing 33 carried by the end bar 11 of the frame. If the operating lever 32 is rocked in a clockwise direction about its pivot, it will engage the stop 31 of the link 27; and, if its movement is continued, the operating lever will carry with it the link 27, thereby rocking the spindle 23 in a clockwise direction and separating the portions of the body 14. When the dumping operation has been completed and it is required to bring the portions of the body together again, the operating lever 32 is swung about its pivot in a contra-clockwise direction until it strikes the stop 30 of the link 27. The swinging of the operating lever being continued results in the link 27 being moved toward the right and the body portions being reunited.

After the rocking of the spindle 23 to an extent suflicient to move the arms 24 out of their dead center position, the weight of the load mi ht cause the portions of the body 14 to suddenly open and, if the operating lever 32 were definitely connected with the link 31, cause the operating lever to swing suddenly over. The same thing might occur, owing to the weight of the body portions, during the closing operation. By the con struction described above, however, I allow a lost motion between the operating lever and the link 27; so that, even if the portions 'of the body 14 should separate, or come to gether, suddenly, the operating lever 32 would consequently be no danger of injury to the operator. The operating lever 32 has pivoted thereto a pawl 34, the end of which engages a series of ratchet teeth 35 formed upon the curved surface of the lever 28. By this means, the spindle 23 is definitely locked in the position in which the body is closed and can only be released by the movement of the operating lever itself. The mechanism for operating the portions of the body, and guiding them in their movement, is the same at each end of the device, except that the actuating lever and locking pawl are omitted at the opposite end to that at which these parts are provided; at that end, the mechanism is actuated by the arm 28 connected to the shaft 29.

The body 14 is formed of sheet metal, strengthened at its edge by angle irons 36. In order to provide for a closed joint between the meeting edges of the portions of the body, I provide angle irons 37 and 38, of which the iron 37 is set somewhat beyond the edge of the body portion to which it is attached, and the iron 38 is set somewhat within the edge of the body portion to which it is attached, so that the edge of the angle iron 37 overlaps the edge of the opposed body portion and abuts against the rocking the spindle 23. The effect of rocking the spindle 28 is that the portions of the body lat are first separated transversely (see Fig. 3), whereby the load is loosened, and then tilted into the position shown in Fig. 4:, the load being thereby dumped. The load, in falling through the space between the portions of the body can, by itsweight, tilt the body portions to a greater extent (Fig. 5), thereby accelerating the dumping operation. When the material has been dumped, the portions of the body can be brought together again by swinging the lever 27 in the opposite direction, which reverses the above described operations.

It will be seen that, by the construction described above, much space beneath the body is saved; in fact the body may be operated quite close to the ground. The compound transverse and tilting movement of the body portions causes loosening of the load from the body and facilitates the dumping. There is no danger to the person operating the dumping mechanism, and no chance of the body opening and dumping its contents accidentally.

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