DUMP-BODY.
Specification of Letters Patent.
ratentea'iyrar. s, 1921.
Application filed April 1, 1919. Serial No. 286,784.
To all whom t may concern:
Be it known that I, I-IALLnT'r D. Enns, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Dump- Bodies, of which the following is a specification.
My invention relates to improvements in dump bodies adapted for use on wagons or tractor drawn trailers.
One of the objects of my invention is to provide a dump body which has a relatively large carrying capacity, which may be easily dumped, which is exceedingly simple in construction and cheap to manufacture, which is strong and durable, and which may be easily and quickly placed in condition for retaining the load.
My invention relates to the type of dump bodies having two bottom portions which incline to a central opening and which is provided with swinging doors arranged to swing toward each other from a closedposition against the inclined bottom portions of the body. In the ordinary construction of this type, the bottom portions of the body incline from the sides of the body to a longitudinal opening extending from one end of the body to the other end, and the swinging doors are mounted on a longitudinal axis and extend lengthwise of the body. lIn my improved construction, I provide a central bottom opening which extends from one side of the body to the other and the body is provided with two bottom portions which respectively incline from the front and rear ends of the body to the opening, and the two doors are pivotally mounted on a transverse axis between the sides of the body. IVith my improved construction, in having the doors disposed transversely in the body instead of longitudinally, the doors are relatively short and more easily operated than in the type having longitudinal doors and the carrying capacity of the body is greater.
My invention provides also novel means for swinging the doors to and holding them in the closed position.
In the accompanying drawing, which illustrates the preferred embodiment of my invention,
Figure 1 is a vertical sectional view of my improved dump body on the line 1-1 of Fig. 2.
Fig. 2 is a top view of the same, partly I broken away. 1 Fig. 3 is a side elevation of the same.
Similar. reference characters designate similar parts in the diiferentviews.4
l designates the two sides of the body, and 2 the ends thereof. The bodyV is provided with a central opening 3 which extends transversely between the side-1. 4 designates two-bottom portions which incline respectively from the ends 2 downwardly to the opening 3 at opposite sides thereof.
A horizontal transverse bar 5 has its ends mounted respectively in the sides 1 above the opening 3 and between the bottom portions 4. Two doors 6 and 7 are hinged to the transverse bar 5, which serve'ssas a transverse axis on which the doorsy can swing toward each other from a closed position against the lower edges respectively of the bottom portions 4, as shown in Figs. 1 and 2. The door 6 has secured to its outer side near the upper edge thereof an angle'plate 8 having a length equal to thewidthof the door i and which, when thedoors are in the closed position, overlaps the door 7 at the upper edge thereof, so as to exclude dirt, when piled above the doors, from passing between them. f
For forcing the doors to the closed position, I provide a transverse rockA shaft 9 which has its ends respectively rotatably mounted in the sides 1 andwhich at one end, outside the body, is provided with an operating crank 10 by which the rock shaft is rocked. The crank 10 is oscillatable between the adjacent side 1 and an arcuate plate 11 is secured to said side and provided on its inner side with teeth 12 with which the crank 10 is adapted to engage for releasably holding the crank in the closed position shown in the drawing.
The rock shaft 9 is provided at opposite sides respectively withtwo arms 13 and 14 adapted to respectively slidably engage two strike plates 15 and 16, which are respectively secured to the inner sides of the doors 6 and 7. y
For releasably securely holding the doors 6 and 7, in the closed position, I provide two transverse rock shafts 17 and 18 mounted in bearings 19, which are fastened to the bottom portions Ll. Each of the rock shafts 17 and 18 is provided with one or more arms 2O adapted to engage the adjacent door 6 or 7, as the case may be, for holding the doors in the closed position, as shown in Fig. 1.
The shaft 17 at one end, outside the body c is provided with a crank 21 which is pivoted to one end of a connecting member,,com prising a bar 22, the other end of whichis pivoted to an operating crank orv lever 23 with which the rock shaft 18 is provided.-`
The crank 23 is manually operated and is located between the adjacent side 1 and an arcuate plate 24, which is secured to the adjacent side 1 and which on its inner side is provided with teeth 25 adapted to releasably engage they crank 23 for holding it in the locking position.
The connecting bar 22 'is attached to the crank 23 below the rock shaft 18 and to the crank 21'above the rock shaft 17. By means of .this construction, when the rock shaft 18 is swung to the locking position, the rock shaft 17 is also swung simultaneously to the locking position. In the operation of my invention, to release the doors, the cranks 10 and 23 are swung to the left, as viewed in Fig. 1, thus releasing the arms 2O from the doors and releasing the arms 13 and 14 from engagement with thedoors 6 and 7, upon which the latter will be swung by gravity and byfpressure of the load to a central vertical position,
upon which the twoV portions of the load willslide 'down the bottom portions f1 and will be discharged through the opening 3 upon the ground directly below.
After the load has been discharged, the crank 10is swung to the right, as viewed in Fi 1, to the ,locking position shown in said gure, upon which the arms' 13 and 14 will engage the strike plates 15 and 16 and force the doors to the closed position. The o erating crank 23 is then swung to the right, as viewed in Fig'. 51,' to the locking position shown in said figure, at which time the arms 20 will engage and hold the doors in the closed position.
The arrangement is particularly well adapted for use in tractor drawn trailers.
I do not limit my invention to the structure shown and described, as modifications,
within the scope of the appended claims, may
be made without departing from the spirit of my invention. Y
lVhat I claim is z- 1. In a dump body of the kind described, a body having a discharge opening and bottom portions inclining toward said opening, two doors hinged to said body and adapted to swing to and from a position against said bottom portions respectively, two rock shafts mountedon said body and having means for respectively holding said doors in the closed position, one of said rock shafts havinga crank, a manually operated l lever secured to the other rock shaft, and a single member connecting said lever and said crank.
2. In a dump body of the kind described, a body having a discharge opening and bottom portions at opposite sides of and in# clining toward lsaid opening, twok doors hingedto the body on a horizontal axis and adapted to swing to and from positions against said bottom portions respectively, a horizontal rock shaft mounted in the body between the doors and parallel with and below the aXis ofthe doors, the rock shaft having two arms arranged to respectively engage the'underV sides of said doors andv force thedoors to the closed position when the rock shaft is turned to the proper position, and a crank secured to the rock shaft outside of the body, substantially as set forth.V f i Y In testimony whereof I have signed my naine to this specification.
