Application filed September 9, 1903. Serial No. 172.509. (No modeL) To all whom t may concer/t:

Be it known that I, WILLIAM E. HARRIS, -a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Dumping- Oarts, of Whiohthe followingis a specification.

This invention relates to dum ping-carts of that class constructed of steel or other metal; and the primary object of the same is to provide a dumping-cart having a tail-gate which is automatically opened and closed by tilting the body of the cart and restoring it to normal position and also one which is equipped with bottom gatesor In oveable bottom sections voperative independently of the tail-gate or simultaneously with the latter, whereby a load may be dumped from the end of the body or through the bottom of the cart or from the end and bottom at the same time.

A further object of the invention is to provide a strong and durable dumping-cart of a comparatively simple construction. j

With these and other objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the body of a cart and one shaft with the wheels removed and embodying the features of the invention. Fig. 2 is a rear end elevation' of the body of the cart with the wheel attachments and shafts or thills removed. Fig. 3 is a longitudinal vertical sec# tion of the parts as shown by Fig. 1, illustrating the tail and bottom gates in open position. Fig. 4. is an enlarged transverse vertical section ofa portion of the body and wheel attaching means.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral l designates a cart-body of usual form, preferably constructed of steel and having a front closed end and a rear open end. The general structure of this body will be the same as that found in vordinary steel or metal carts, so far as bracing or binding the edges thereof is concerned. The body l is secured to and supported on sills 2, which are formed of channel-iron, with their open portions inward, and provided with wood-llers 3. These sills 2 are projected in rear and in advance of the opposite ends of the lower portion of the body 1 and possess superior characteristics of strength and durability to resist breakage, particularly at the rear ends, which strike the ground or other surface when the body 1 is dumped. By the use of the sills 2 with their wood-fillers, as set forth, the cost of repair and inconvenience is reduced to a minimum. The under edges of the sills have hinge-plates 4. secured thereto and cooperate with similar plates '5, bolted to the rear extremities of the thills 6, which are projected under-the sills and are mortised to receive the said plates 5. The front end of the body 1 is inclined forwardly and attached thereto is Y a fastening device in the form of an elongated hook 7, adapted to removably tit in a slot 8,' formed in the center of the cross-bar 0f the thills, the said slot 8 being intersected by a vertical opening 9 to receive'a headed pin 10, which is also passed through the lower hooked terminal of the fastening device to prevent accidental displacement of the latter. While this is a preferred construction, it will be understood that any form of hook might be substituted with equal efficiency in holding the bodyl in normal position in relation to the thills. To opposite sides of the body 1 plates 11 are securely fastened and have stub axles 12 projecting outwardly therefrom to receive wheels, the lower extremities of the plates being normally deflected, as at 13, and rest on the upper edges of the sills 2. The lower angularly-defiected ends 13 of the plates are secured to the sills 2 by bolts 141, and the latter are also utilized in fastening the hinge-plates t against the under edges of the sills.

The lower portion of the body -1 is closed by hinged gates 15 and 16, as clearly shown by Fig. 3, each of these gates having out- Wardly-projecting fulcrum irons or members 17 secured to opposite edges thereof and bearing in the wood-fillers 3 in the sills, as indicated byv Fig. 2. The said gates also have angular arms 18 secured to their opposite ends adjacent to their meeting ends, the said arms partially depending below and passing outwardly under the sills 2 and provided with eyes or analogous devices 19, to which chains or other iiexible operating connections 2O are attached and run through a single chain or other connection 21, passing upwardly over a guide pulley or sheave 22, applied to the upper portion of the side of the body 1. These connections and guide-pulleys will be duplicated on opposite sides of the body, and the single chain or analogous connections 21 extend forwardly and wind on and unwind from a drum 23, held in suitable bearings 24, secured to the front end of the body. The drum 23 is operated by a hand-lever 25, having thereon a spring-actuated latch or dog 26, which engages a toothed pinion or ratchet-wheel 27 on one end of the drum. By successively reciprocating the hand -lever 25 and locking the drum 23 against rotation through the medium of the latch the chain or other connection 21 can be wound on the drum and draw the gates 15 and 16 upwardly against the lower portion of the body 1 through the medium of the chains or other connections 20. By releasing the latch 26 from the ratchet-wheel 27 the drum will be free to rotate and allow the chain connections to rapidly pay off and quickly open the bottom gates, especially when a load is imposed thereon. These bottom gates render the improved cart especially useful in relieving the body 1 of its load on a level when it is not required to dump the cart to deposit the load.

The improved cart is also equipped with a sliding tail-gate 2S, having upper and lower outwardly-projecting apertured ears 29 and 30, arranged in transversely-alined pairs. Fulcrumed at intermediate points on the bearings of the guide-pulleys 22 are tail-gateactuating levers 31, one on each side of the body, the said levers having their forward extremities deflected downwardly at an angle, as at 32, to give them the proper throw and pivoted at their front ends to the upper ends of connecting-bars 33, in turn pivoted at their lower ends to the thills 6. The rear ends of the actuating-levers 31 are inserted through the ears 29 and secured in place by cotter-pins 34, and between the fulcrums of the said levers 3l and their rear ends the upper ends of lifting-bars 35 are pivotally attached and have their lower ends bent at an angle and inserted through the ears 30 and secured by Cotter-pins 36. The actuating-levers 31 are automatically set in motion to open and close the gate 28 when the cart-body is dumped and restored to normal position, and the movements and positions of the said actuating-levers and cooperating parts, as well as the gate 28, is clearly shown by Fig. 3. When the cart-body 1 is released and permitted to dump, the connecting-bars 33 pull downwardly on the forward extremities of the actuating-levers 31, and thus throw the rear extremities of said levers upwardly and lift the gate 28, as well as throw it outwardly at an angle in relation to the rear open end of the body 1.

This angular disposition of the gate 28 when the actuating-levers 31 are operated by the movement of the body is due to the continued downwardly-drawing action exerted on said actuating-levers through the connecting-bars 33, and the operation of the gate is steadied through the medium of the lifting-bars 35. The actuating-levers and connecting-bars 33 are so proportioned that when the gate closes it will be drawn closely against the rear end of the body, and after the latter has been relieved of its load and is gradually restored or thrown back to normal hrizontal position in relation to the thills the forward extremities of the actuating-levers are pushed upwardly, and the rear extremities of said levers are consequently thrown downwardly. In dumping moist material both the tail-gate 28 and the bottom gates 15 and 16 may be caused to operate to relieve the body 1 more rapidly of such load and prevent sticking of any part thereof within the body. This will expedite the dumping operation.

The improved cart will be found exceptionally convenient in its use and in view of its strength and durability will form a valuable acquisition to the art to which it pertains.

It will be understood that changes in the proportions, dimensions, and minor details may be resorted to Without departing from the spirit of the invention.

Having thus fully described the invention, what is claimed as new is- 1. A dumping-cart body having a bottom fully open from the front wall to the rear end thereof and also provided with a rear open end, a single gate for the rear open end of the body, a pair of gates for closing the bottom of the body, said gates having independent operating means, and means connected to the opposite sides of the body for supporting the latter to fully clear the under side of said body and permit the bottom gates to have free operation in their opening and closing movements, the said bottom gates being fulcrumed adjacent to the opposite ends of the body and opening from the center.

2. A dumping-cart, having a body movably attached to thills and provided with a fullyopen rear end and bottom, an end-gate connected to the thills for automatic operation to release the load by the dumping operation of the body, gates coperating with the open bottom of the body and movably attached adjacent to opposite extremities of the latter, said bottom gates opening downwardly from the center, and having initial actuating means applied to the front end of the body for operation simultaneously with the release of said body for dumping action whereby both the end and bottom gates may be simultaneously operated to release the load through both the bottom and rear end of the body.

3. In a dumping-cart, the combination of a body fully open at the rear end and bottom, supporting means attached to the lower part of the body and located to one side of IOO IIO

the open bottom to give full clearance to the latter, gates coperating with the rear end and bottom of the body, independent means for releasing and closing said gates, and thills to which the saidl supporting means are hinged.

4. In a dumping-cart, the combination of a body having dumping means at the bottom, sills for the bottom, formed of channel-iron and projected outwardly clear of the bottom of the latter, wood-llers in the sills to lighten andstiien the same, thills to which the said sills are movably attached, and end and bottom gates for the said body having independent operating means, the bottom gates being free to move downwardly and upwardly between the opposite side portions of the sills.

5. In a dumping-cart, the combination of draft devices, sills formed of channel-iron and movably attached to said draft devices, a body secured to the sills and having end and bottom gates, the said sills being projected outwardly beyond the opposite sides of the body and clear of the bottom of the latter, stub-axles secured to the outer portions of the sides of the body and resting on the sills, and means for opening and closing the said gates.

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

WILLIAM E. HARRIS.
