DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 714,286, dated. November 25, 1902.

Application filed fileptember 16 1902. Serial No. 123,622. (No model.)

mentsin vehicle-bodies,and particularly to they dumping type, the object in view being the production of a body having doors forming the bottom thereof and loosely mounted, so as to be capable of vibration when in an open condition.

In constructing a vehicle-body after the manner of the present invention a further object is attained in the particular means of supporting the doors forming the body, whereby said doors may be caused to assume an inclined plane when in an open condition, with the upper edges thereof lying beneath the lower edges of the side-boards of the vehicle.

. With these and other objects in View the invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described plan view of the structure disclosed in Fig. 1.

Fig. 4 represents an enlarged detail fragmentary perspective view of a portion of one of the doors, illustrating the chain hinges therefor. Fig. 5 represents an enlarged, detail fragmentary view of one of the supporting chain brackets.

In the art to Which the present invention relates vehicle-bodies have been constructed with doors forming the bottoms thereof and hinged to the side-boards rigidly, so as to swing downwardly and assume a vertical plane when in an open condition, and it is further common in the art to support the doors forming the bottom of the body of a vehicle by chains attached on the inside of the side-boards, whereby the said doors assume vertical planes and extend within the vehicle-body when in an open condition; but

serious objections have arisen to both the constructions described, in that in closing the doors after'a discharge of the contents of the vehicle-body quantities of the load carried by the vehicle are usually caught by the edges of the doors and cause the same to spring and become jammed, loosening the con necting and supporting parts and sometimes causing a serious injury to the doors, the prime object of the present invention being to avoid these serious results by providing means whereby there is the least possibility of either of the doors collecting any of the matter being discharged from the body of a vehicle and, further, whereby the small quantity which may accidentally come in contact with said edges will be forced therefrom by the closing movement of the door without any springing or binding action upon the parts. These valuable functions are attained by the present invention, one embodiment of which is depicted in the accompanying drawings, in which 1 indicates any suitable vehicle-body made up of side-boards 2 2 and front and rear end-gates 3 3, which latter may be of any suit-able construction and positioned on diagonal planes or vertical, as may be desired. The bottom of the body 1 is formed of doors 4 4, each of which has attached thereto a plurality ofchain hinges 5, each of said hinges being made up of a chain attached to the outside of a side-board, as at 6, and to a door, as at 7, a suitable wearingplate, as 8, being secured to each of the respective doors 4 at the point of the hinge for receivin g the weartherefrom, the said plate being preferably cupped, as indicated in Fig. 4. A plurality of braces 9, of suitable material, preferably metal, extend downwardly from each of the side-boards 2 2 past the upper edge of each of the respective doors 4 for bracing the same when in a closed position and limiting the same against lateral movement when open. Attached to the inside of each door 4, preferably near the inner edge thereof, is a chain 10, which extends upwardly through the respective side-board 2 about a"pulley 11, carried by a bracket 12, extendinglaterally from said side-board, and the chain thence extends forwardly and is attached to .a windingshaft 13, which shaft may be provided with any preferred form of pawl-and-ratchet looking mechanism 14. Each chain 10 is of a and the doors 4 dropped under the weight of the contained load, said doors in dropping assuming diagonal planes owing to the supporting chain hinges 5 and the chains 10, whereby the upper edges of said doors are held beneath the respective edges of the side-boards, therebyobviating to a great extent the danger of foreign matter being lodged upon the said upper edges of the doors. After the load has been discharged it is only necessary to wind the shaft 13 to lift the doors to a closed position, said doors in the lifting movement bringing their inner corners first into contact with the inner corner of the respective side'- board and the said corner of the door then moving transversely across the lower edge of the side-board and driving before it any foreign matter which may possibly have been retained by the said. edge or which may have become lodged upon the lower edge of the side-board, whereby each door 4 is self-cleaning, the cleaning operation being performed each time the door is closed.

In the repairing of roads it is often found desirable to discharge a small quantity of crushed stone at a given point, and this is usually accomplished by shoveling the desired quantity from the supply-vehicle, and in order to obviate the necessity for this shoveling process I contemplate providing each door with a sliding gate 15, provided with a suitable operating-handle 16 and slidably retained in position by any preferred form of frame 17, attached to the respective door. When only a small quantity of contained material is desired to be deposited, it is only necessary to grasp the handle 16 and withdraw the gate 15 to the desired extent, then replace the same, the contained material automatically discharging itself and the discharge being cut off by the closing of the door.

Although I mention chains throughout the specification, it will be understood that where such term is used I refer to any suitable cable and do not limit myself to a link construction, and it will further be understood that I am aware that it is old in the art to employ brackets for guiding the chains 10 in the manner disclosed, so that I shall not limit myself to any particular construction of brackets and do not desire to be understood as posing as the inventor of a chain passed through the side-board, but may change this construction as I may find desirable at will, the disclosure of the particular device mentioned being the best for illustrative purposes of the present invention. Other features of the structure may be altered as may be found necessary, and I shall not consider myself limited to the minor details herein specified, but shall deviate therefrom to any extent within the spirit and scope of the present invention.

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

1. In a vehicle-body the combination with side-boards, of doors forming the bottom of said body, and chains connecting the under sides of said doors with the outside of said side-boards, and supporting said doors when in an open condition with the upper edges thereof normally beneath the lower edges of the respective side-boards, the upper edges of said doors being left free to swing or vibrate, substantially as described.

2. In a vehicle-body, the combination with suitable side-boards, of doors forming'the bottom of said body, flexible hinges connecting the outside of said doors with the outside of said side-boards and having the upper edges thereof free for lateral movement when the doors are in an open condition, and means for supporting said doors in a closed condition, substantially as described.

3. In a vehicle-body, the combination with suitable side-boards, of doors forming the bottom of said body, chain hinges connecting the outside of said doors directly to the outside of said side-boards, and means for supporting said doors in a closed condition, substantially as described.

4. In a vehicle-body, the combination with suitable side-boards, of doors forming the bottom of said body, flexible hinges connecting said doors directly to the outside of said side-boards, and independent means forlimiting said doors from swinging beyond a diagonal plane when being opened, substantially as described.

5. In a vehicle-body, the combination with suitable side-boards, doors forming the bottom of said body, flexible means between each of said doors and the outside of its respective side-board, a cable connected with each of said doors, and means for swinging said cable for closing the doors, substantially as described.

6. In a vehicle-body, the combination with suitable side-boards, of doors forming the bottom of said body, flexible means connecting said doors and the outside of said side boards, said doors being left free to swing thereon, braces secured to the side-boards and extending beyond the edges of said doors, and means for supporting said doors in a closed position, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
