DUMP BODY.
Application mea April 29, 192i. serial no. 187,664.
Our invention relates to dump bodies. It is the object of our invention toprovide a dump body whichk will automatically. dump when loaded and when released. It is a particular object of our` invention to provide a construction that will be self contained and rigid to yprevent any 'warping of the supportf'ng mechanism which will throw the tilting and unloading mechanism out of alignment so as to prevent it properly functioning. It is a further object to p rovide the supports for the tilting mechanism ofy such `character Vthat they will serve the purpose of tyingthe chassis frame together.
It is an additional object of our invention to provide the combination of a dump body supported on the chassis frame indirectly.
It is a further object to provide an arrangement by which the supporting brackets for the dump body and the points ofconnecti'on of the brackets with the cross rods of the chassis frame are all inside of the chassis frame and inside of a-supplementary frame thereby protecting the brackets andl preventing injury to persons who may be ad]ace'nt to the mechanism when it is' operating.
Referring to the drawings,
Fig. 1 is a side elevation of the complete mechanism;
Fig. 2 is a rear elevation thereof; y
3y is a detail side elevation 'of a supporting bracket and the associated supporting mechanism, thesupp'orting mechanism being shown insectiong- Fig. 4 is a section on the line 45-4 of Fig.
1 looking in the direction of the arrows;
Fig. 5 is a front elevation of the supporting leg.
, Referring to the drawings in detail, 1 represents a chassis frame which is connected together by a straight tube or rod 2 mounted in depending side plates' carried by the side members 4 of a supplementary frame which is'inounted 'upon the chassis frame 1.
which the supplementary frame 4 tied to` gether by the transverse angle members 5 and V6 is provided carryingthe depending side f plates 3 within the chassis frame and connected together by the supporting bolts 'or rods 2, 7 and 8, rods 7 and 8 being kicked,
'up centrally as at 9 and 10 to provide suit'- able clearance and adequatestrength ofthe parts. The supplementary side .members 3 `The rod 29 is placed behind the' shoulder 33 Thus' a ui'iita'ry construction is provided-by are bolted vto the supplementryframe 4 by 55 the bolts 11 and vare spaced by the spacing blocks 12. The dump body 13 has connectedv to its side rails 14 oneither side thereof a bracket consisting of a vforwardly disposed downwardly extending vertical frame meinber 15 terminating ina jaw 16 which rocks upon 'the transverse rod 8. A secondl depending member 17 extends downwardly f spaced from the member 15 and somewhat rearwardly at thebottom so that its genera-l direct'on is diagonal. This member 17 terminates in a jawv 18 riding upon the rod V7, The two jaw portions are Connected together by a web 19. A second web L2() connects the jaw 18 with a jaw l21 which is formed on ythe end of a depending diagonally disposed armf22. From either side of the jaw 21 extends an arm having a Ubolt 123 which extends around" the bottom of the transverse rod 2 on which the `jaw 21 is 'adapted "to be mounted and with which it engages when the bodyis in'dnmping position. l
These two side framemembers are connected together by crossed 'diagonally disposed brace rods 24 and 25. These cross frame members 'are connected toeyes 26V on vthe brackets. If it is 'desired to maintain the body in elevated p'ositifonthe stiif leg 27 is provided pivoted at 28.y This leg 'is provided on either side of the body and the arms of the legs arejoined together by a rod 29 to which is connected thevusu'al chain 3 0. The spring 31 and the chain 32 are connected tothe supplementary frame 4 'and body 13.
on the supplementary frame when the `body is in its elevated position. The lever 46'will unseat the rod '29 through the chain connection 30.
The dump body is provided with the usual rear tail gate, the exact details of which are not important.
kThe forward end of the body' is provided with a transverse rod known as va locking rod 34 engaged by a locking head 35 pivoted at 86 on the supplementary frame. A rear* wardly extending arm 37 is also provided mounted on the frame to which is pivoted a lever 38 having anunlocking plunger 89 passing through the angle ironsu'pport 40 tothe front end of the body `and adapted to engage with the locking headf to lock it against the resistance of the spring 41 which normally maintains the locking head in locking position, such spring being supported at its free ends by the bracket 42 mounted on the cross frame menr ber 40. This lever 38 and bolt 39 are actuated by the pitman 43 connected to a lever 411 pivoted on the cab frame member 1.
This lever 38 and bolt 39 are actuated by the pitman 4:3 connected to a lever 4:4 pivoted on thc cab frame or floor board at 15. The lever 4 4; terminates in av handle 46 adjacent the drivers seat 47. Thus the body can be unlocked from the driyers seat and as the weight of the load is greater to the rear of the pivotal support on the rod 8 than in front of the pivotal supportthe body automatically tilts rearwardly first bringing `the jaw 18 on the rod 7 and then the jaw 21 on the rod 2 so that the load dumps. the tail gate heilig opened up automatically in the usual manner to permit of the discharge of the load.
Method of operation.
When the lever 46 is pushed forwardly by the operator on the seat 47 the bolt 39 moves the locking head 35 forwardly against the resistance of the spring .4l disengaging the head of the locking head 35 from the latching rod 3l on the body thereby releasing the body. The weight being greater on the rear of the body with respect to the rod 8 than on the forward part of the body, the body 4 automatically tilts rearwardly until the jaw 18 engages with the rod 7. Then the jaw 16 lifts off of the rod 8 and the body continuing in its rearward movement is finally brought to rest by the engagement of the jaw 21 with the rod 2 and the engagement of the dump body with the cross frame As soon as the load is dumped, the body being heavier when empty in ,front of the rod 2 than to the rear thereof, thebody will automatically return Vto its initial position. It will be prevented from continuing its forward arcuate movement by the4 restraining eect of the U bolts 23 which pass beneath the rod 2. In its return movement the brackets first engage through the jaws 18 of the rod 7 and then lift the jaws 21 ofi the rod 2 and finally reengage the rod 8 through the jaw 1 6.
The cross frame members 2l and rigidly tie these supporting brackets together and prevent any warping or non-alignment of the parts so that the brackets always are accurately positioned with respect to the supplementary side frame members 3, the cross rods 2, 7 and 8 and the dump body supported by the brackets.
The abuse imparted to a structure of this sort is extreme. The loads are dumped into the body usually from an elevation from a steam shovel dipper bucket and not only contain earth but often times rock or large pieces of rock. The operators operate the vehicles in the worst kind of terrain where jars and twisting strains of all sorts are customary and common and necessary and the operators themselves are usually of the type that is largely unskilled and neglectful of equipment, so that the equipment must be self sufficient and self contained and so rigid and strong that ordinary usage will not throw the parts out of alignment.
This equipment is used largely by contractors to whom time is of the essence and any breakdown of equipment would be eX- tremely serious in causing failure to perform the contract on time.
Hence it is essential to have a construction that can not get out of alignment, that can not come apart, and a construction in which any accumulation of dirt, mud. small parts of rock and the like will not injure.
t is further necessary to have the entire dump body unit consisting efV the dump body, the interlocking and inter-locked `l'n'ackets and the supplementary frame, so
constructed as to be able to drop them as a unit on to the chassis frame.
`This type of equipment is manufactured by dump body manufacturers who sell their dump bodies and associated equipment to those who either own the chassis frame or those who will assemble the chassis frame and dump body for sale to others. The truck with the chassis frame is one unit of manufacture and the equipment explained in this specification is another item. Hence it is essential that the two items be so constructed that they are independent of one another and can be assembled by the easiest method possible. Hence the dump body, supplementary frame, brackets, and associated mechanism have been constructed as a single self contained unit adaptable to any proper form of chassis frame.
It will be understood that We desire to comprehend within our invention such modifications as may be necessary to adapt it to varying conditions and uses.
Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:
1. In combination, a dump body, a pair of spaced brackets, means tobrace said brackets with respect to one another and to rigidly tie them together as a unitary support for said body, a plurality of spaced support engaging jaws on said brackets, a supplementary frame, inwardly disposed depending, supporting and guarding plates mounted on either side of said frame, supporting rods connected therebetween adapted to engage with said jaws on said brackets and U bolts spaced from a pair of said jaws adapted to pass around one of said supports to prevent the brackets from being detached entirely from the supports and limiting the movenient of the body with the brackets in one direction.
2. In combination, a dump body, a pair of' spaced brackets, means to brace said brackets with respect to one another and to rigidly tie them together as a unitary support for said body, a plurality of spaced support engaging jaws on said brackets, a supplementary frame, inwardly disposed depending,
