6 Claims. (01. 105270) My invention relates to improvements in dumpbodies for vehicles wherein a pivotally mounted body has an inclined bottom to produce a greater capacity upon one side of its pivotal axis than the capacity upon the opposite side thereof, said lesser capacity side being weighted and heavier than the greater capacity side only when said body is unloaded, said body operating in conjunction with a series of connected latches arranged to engage said body and prevent movement thereof from and to loading and dumping positions, whereby said body may be moved, when loaded or unloaded, from, and to, said dumping and loading positions respectively, by the attraction of gravity when said latches are released.

The primary object of the present invention is to provide a new and improved dump-body.

Another object of the invention is to provide a new and improved dump-body having improved means for automatically moving said body to and from loading and dumping positions, as may be required.

A further object is to provide a new and improved device of the character set forth having improved means for automatically moving a dump-body from loading to dumping position and from dumping to loading position.

A still further object is to provide new and improved means for retaining a dump-body in either loading or dumping position, and for releasing said body from either position.

A still further object is to provide a single element, which, when actuated, will release said body from either position.

A still further object is to provide a new and improved dump-body which, will normally be pivotally supported in an unbalanced state to move said body to a dumping position when loaded, and to move said body to a loading position when unloaded.

I accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present application, wherein like characters of reference are used to designate similar parts thruout the specification and drawings, and in which- Fig. 1 is a partly broken end elevation of my improved dumping-body mounted upon a vehicle;

Fig. 2 is a side elevation thereof; and

Fig. 3 is a partly broken plan view of the device.

Referring to the drawings the numeral 2 is used to designate in general a suitable supporting frame mounted upon a suitable vehicle I, which may be a rail-car, as illustrated, or any other suitable vehicle adapted for transportation.

Pivotally mounted upon the frame 2 is a body 3 having an inclined bottom 4, which bottom 4 is inclined transversely thru the longitudinal axis of the pivotal support 6 of said body 3, as disclosed in Fig. 1 of the drawings, whereby the body 3 has a greater capacity upon one side of its pivotal support 6 than the capacity of said body 3 upon the opposite side of said pivotal support 6, whereby said greater capacity side of said body 3, when loaded, will be actuated by the attraction of gravity to move the said body 3 to a dumping position in a manner hereinafter more fully set forth.

The lesser capacity side of the body 3 is provided with a suitable weight 1, while a second weight 8 depends from the body 3 and directly under its pivotal support 6, the weight of said combined weights and the weight of a load in the lesser capacity side of said body 3 being less than the weight of a load in the greater capacity side of said body 3 when said body 3 is loaded.

The side of the body 3 adjacent, or on, the greater capacity side is open and a door 9 is hingedly suspended from the body 3 and is actuated by the attraction of gravity to close said side when the body 3 is in a loading position, and to normally open said side when said body 3 is in a dumping position, as disclosed in dotted lines in Fig. 1 of the drawings.

Rotatably mounted within the frames 2 on each end of the vehicle I are transverse shafts ll, each being provided with a series of latches l2, l3 and I4, rigidly connected to their respective shafts H, and engaging, respectively, stops l5 and I6, mounted upon the ends of the body 3, and catches ll projecting from the bottom of the door 9, said series of latches I 2, l3 and I4 being thus connected so that the body 3 may be released from either dumping or loading position in a manner hereinafter more fully set forth.

Each shaft II is provided with a depending lever or arm l8 to which are connected rods 2| passing thru suitable supports 22. A spring 23 is interposed upon each rod 2| and between said levers l8 and the supports 22, as disclosed in Figs. 2 and 3 of the drawings.

Links 24 connect said rods 2| to opposite sides of the pivot 26 of an operating or releasing lever 21 whereby one movement of said lever 2'! will actuate the shafts I l and move all of the latches I2, i3 and M to disengage their respective stops l5 and 16 upon the body 3 and the catches I! of the swinging door 9, and against the tension of the springs 23, which tension will tend to normally retain engagement of the latches with their respective stops.

The body 3 is held in horizontal or loading position by means of a suitable longitudinally disposed support or angle iron 28 secured to the frames 2 and under the lesser capacity side of the body 3.

In operation when the body 3 is loaded, the greater capacity side, or that side adjacent the open side or door 9, is the heavier.

When the operating lever 21 is moved to pull the rods 2I against the tension of the springs 23, the levers I8 partially rotate or oscillate the shafts I I and the latches I3 and I 4 are disengaged from their respective stops IS and catches H on opposite ends of the body 3, and the attraction of gravity, acting upon the load of greater capacity on that side of said body 3, will lower the said body 3 to dumping position, as disclosed in dotted lines in Fig. l of the drawings, and, the catches I I being released, the door 9 will swing open by gravity and the load will slide from the inclined bottom 4 thru the open end of the body 3 and be discharged.

When the body 3 moves to such position, the stops I5 on opposite ends of said body 3 will be moved into a position where they are readily engaged by the latches I2, and said body will thus be held, or retained, in dumping position by said latches I2, so that any lodged or unloaded matter may be liberated and removed, or permitted to slide down the inclined bottom 4.

After the load has been duly discharged or dumped, the operating lever 21 is again operated, which will oscillate the shafts II, as hereinbefore described, against the tension of the springs 23, and release the latches I2 from engaging relation with their respective stops I5, and, the now heavier side of lesser capacity (upon which the weight 'I is attached), will, operating in conjunction with the depending weight 8, be actuated by the attraction of gravity and the body 3 will be automatically moved to a loading position and supported upon the longitudinal support or angleiron 28, as disclosed in full lines in Fig. 1 of the drawings.

As the door swings closed, the catches I1 thereon, being provided with beveled ends II, will move between the latches I4 and the ends of the body 3 and move said latches I 4 outwardly to permit the passage of said catches I'I beyond said latches I4 and thereby permit said latches I4 to drop back into securing position.

I claim:
