DUMP BODY FOR TRUCKS.

Application led February 27, 1925. Serial No. 11,990.

To all whom t may concern.'

Be it known that I, RAY J. WINGER, citizen of the United States of America, residing at Brush, the county of Morgan, and State of Colorado, have invented certain new and useful Improvements in Dump Bodies for Trucks; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in the construction of dump bodies for trucks. In the transportation of materials of various kinds, a large amount of time and labor can be saved if the load can be readily dumped as the labor of unloading canI thereby be reduced to a minimum.

I am, of course, aware that many different means for operating dump] bodies have been invented, many of which are in use today. I have, however, invented a specifically different dump body than any that is at present known to me. The ob] ect of my invention is to produce a dump body that shall be adapted more particularly to horse drawn trucks and which shall be so constructed that the power required for hoisting and dumping shall be supplied by the team.

The above and other objects that will become apparent as the description proceeds are attained by means of a construction that I will now proceed to describe in detail, reference for this purpose being had to the accompanying drawing in which the present preferred embodiment of the invention is shown and in which v Fig. 1 is a side elevation of my improved dump body, showing the same in place on a truck.

Fig. 2 is a section taken on line 2-27 Fig. 1.

Fig. 3 is a section taken on line 3-3'. Fig. 1.

Fig. 4 is a side elevation showing the body in dumping position.

Fig. 5 is an end view, with 1warts broken away and parts shownV in section, said view being taken along line 5-5, Fig. 4 and shows the dump body in tilted position as it appears bef-ore the body has been hoisted.

Fig. 6 is similar to Fig. 5 and shows the body both hoisted and tilted.-

Fig. 7 is a view taken along line 7-7, Fig. 5 and shows the manner in which the cables are resiliently attached to one of the side members and Fig. 8 is a detail showing the double drum to which the ends of each pair of hoisting cables are attached.

The truck that I have shown has merely been indicated for the purpose of better illustrating my invention and is n0 part of the invention. The truck has a pair of front wheels 1, a pair of rear wheels 2, reach 3 and holsters 47 in the usual manner. Transverse timbers 5 rest on the upper surface of the holsters 4 and are secured to the latter by means of clamping rods 6. To the upper side of the transverse members 5, I secure two parallel spaced beams to the upper side of which I secure a number of transverse frame members 8, that are secured to the beams 7 by means of bolts 9, or other suitable means, and I preferably provide four transverse frame members 8. To the ends of members 8- I attach hooks 1()` whose function and mode of operation will hereinafter appear. At the rear and front of the side beam 7 I secure vertical standards 11 that are held in place by bolts 12 that pass transversely through the frame in the manner shown in Figs. 5 and 6. These uprights are braced by means of diagonal braces 13 and have attached totheir tops castings 14 (Fig. 3) each of which carries two pulleys 15 over which the cables 16 run. A shaft 17 extends lengthwise of the frame and is journalled in the transverse pieces 18. Near each end of shaft 17 I secure spaced collars 19 (Fig. 8) which form spools on which the cables 16 may be wound in the manner shown most clearly in Fig. 8. A drum 20 is secured to the shaft 17 about midway between its ends. A cable 21 is wound onto the drum 20 and has one end attached to it. The other end of this cable carries one or more links to which a whiiiietree may be attached. A team of horses may be attached to the whiflletree for the purpose of rotating the shaft and for winding the cables 16 thereonto. The box or body in which the load is carried consists of a plurality of transverse members 22 whose ends are connected by means of longitudinal beams 23. A plurality of scantlings or two by fours 24 are secured in parallel relation tothe upper surface of the transverse members 22 and to the upper side of these the floor 25 is cured. Ends 26 are secured to the front and rear of the bottom and these cooperate with the sides 27 to form a box. The sides are hinged so as torotate about the axes of the rods 28. Rods 29 are secured to the lower side of the transverse members 22 and are so spaced that they rest in the hooks 10 in the manner shown in Fig. 2. lVhen the box is tilted it rotates about one of the rods 29 until it is in position to be hoisted.

By referring more particularly to Figs. 4 to 8, we will see how the device operates. The cables 16 shown to the right in Figs. 5 and G pass through suitable openings in the beam 23 and are anchored to the latter. The cables on the left, however, are about two feet longer than those on the right and pass through holes in member 23, thence around pulleys 30 through notches or openings in the brackets 31 and are joined to the free ends of the springs 32 whose other ends are anchored to brackets 33 in the manner shown most clearly in Fig. 7. Secured to the end of each cable 16 adjacent its connection to the spring 32, is an enlargement or ball 34 that engages the bracket 31 and forms a stop which limits the movement of the cable. The ends of the beams 23 project over the uprights 11 and are provided with pulleys 35 that engage in and cooperate with the guide grooves 36. The tension of springs 32v is sufficient to prevent any slack from forming in the cables to which they are attached.

Let' us now assume that the parts are in the position shown in 2 and that a force is applied to the cable 21 which is sufficient to rotate the shaft 17. The cables 16 will be wound onto this shaft in the m'anner obvious from the drawing. The right hand side of the box will be raised in the manner shown in Fig. 5. The cables that are attached to the left hand beam 23 will slide through the same until the member 34 engages the bracket 31 when the relative movement will cease and both sides will thereafter be hoisted at the same rate until the parts assume the position shown in Fig. 6. The amount of inclination of the bottom may be as great as necessary to effect complete dumping of the particular material handled.

I want to call particular' attention to the construction which permits the box to be first tilted and then hoisted to the extent necessary. It is not always necessary to raise the box as the unloading may, obviously, take place by merely tilting the box, but it may be necessary at times to hoist it also. The idea of having the cables on one side so connected that they will slide for some distance gives a simple mechanism for tilting which I believe to be new.

Having now described my invention, what I claim as new is:

1. In a dump body construction, in combination, a. supporting frame, vertical standards at each end thereof, a body supported by the frame and located between said standards and means for hoisting the opposite sides of said body to different heights, said means comprising a cable for each corner of the body, the cables attached to one side having a lost motion connection with the body whereby they will not become effective for the purpose of raising the body until the other side has been raised to some distance.

2. In a dump body construction, in combination, a supporting frame, vertical standards at each end thereof, a body supported by the frame and located between said standards and means for hoisting opposite sides of said body to different heights, said means comprising hoisting drums secured to the frame beneath the body, cables having one end connected to a drum and the other end connected to opposite sides of said body, the cables that are connected to one side of the body having a lost motion connection 90 with the body and the cables connected to the other side being positively connected to the body whereby when the hoisting drums are operated the body will be tilted before it is hoisted.

3. In a dump body construction, in combination, a frame having vertical standards near each end, a body member adapted to be supported on said frame between said standards, a shaft rotatably connected to the frame and extending lengthwise thereof, said shaft having hoisting drums near each end, said drums being each located underneath in the plane of one pair of said standards, pulleys secured to the standards near the tops thereof, cables having one of their ends attached to said drums and the other ends being connected to the body, one cable near each corner of the body, the twocables on the side to which the load is to be vdumped having a lost motion connection with the body and means for rotating the hoisting drums.

4. In a dump body construction, in combination, a frame having vertical standards nea-r each end, a body member adapted to be supported on said frame between said standards, a shaft rotatably connected to the frame and extending lengthwise thereof, said shaft having hoisting drums near each end, said drums being each located underneath in the plane of one pair of said standards, pulleys secured to the standards near the tops thereof, cables having one of their ends attached to said drums and the other ends being connected to the body, one cable near each corner of the body, the two cables on the side to which the load is to be dumped having a lost motion connection with the body and means for rot-ating the hoisting drums, said means comprising a drum secured to the shaft intermediatethe hoisting drums.

5. In a dump body construction, in combination, a fra-me having Vertical standards near each end, a body member adapted to be supported on said frame between said standards7 a shaft rotatably connected to the frame and extending lengthwise thereof, said shaft having hoisting drums near each end, said drums being eaeh located underneath in the plane of one pair of said standards, pulleys secured to the standards near the tops thereof, cables having one of their ends attached to said drums and the others ends being connected to the body, one cable near each corner of the body, the two cables on the side to which the load is to be dumped having a resilient lost motion conneetion with the body and means for rotating the hoisting drums.

In testimony whereof I alix my signature.

RAY J. WINGER.
