GEORGE B. ALLIS, OF LITTLE ROCK,` ARKANSAS.

WOODV AND CQAL'ELEVATOR.

SPEGIFICATIQN forming part of Letters Patent No. 256,452, dated April 18,1882.

Application filed March 2, 18d?. (No model.)

To all whom it may concern:

Be it known that I, GEORGE B. ALLIs, of Little Rock, in the county ofPulaski and State of Arkansas, have invented certain new and useful Improvements in Wood and Ooal Elevators; and I do hereby declare that the foly in g devices for wood and coal stations on rail- Fig. 2, a vertical section of same; Fig. 3, a verroads, dan.; and it consists in details of construction and arrangement of the several parts that will be hereinafter more fully set forth in the specification and claims and pointed out in the accompanying drawings, in which- Figure 1 is a front elevation of my device 5 tical section showing the box or receptacle opened; Fig. Il, a vertical section of the box closed; Fig.v 5, a perspective view of the side guides and supports Fig. 6, a plan view of the catch by means of which the fuel-box is held in position and locked or unlocked.

The object of the invention is to provide an easy and ready method for dumping coal and Wood into the tender of a locomotive and directly measure the quantity thus thrown in. Generally when locomotives are stopped for the purpose ot' taking on fuel the train-hands are required to throw the wood into the tender. This requires loss of time and labor. By my device the wood can he dumped into the tender by the reman of the locomotive in the same manner that the tender-tanks are filled with water from the supply-tank. To attain this I provide a suitable frame-work consisting of the posts or uprights A, secured by crossbeams B B', the Whole frame being elevated above the ground to enable a fuel-box, O,Wheu raised, to be easily discharged into the tender of a locomotive. The box C is provided with a hinged end piece, D, and is supported on and hinged to a platform, F, which moves up and down between the posts `A as guides. Also, pivoted to the platform F 'are the elevatin g-pieces I,wl1ich are also guided by the posts A. Pulleys N are fastened to the cross-beam B and pulleys P Q to the pieces l and top of the frame, respectivel y. Ropes L pass from a capstan, V, around the pulleys, and thence toey'es Q in the platform F. To raise or lower the platform and box it is only necessary to wind or unwind the cords L byl means of the capstan. The operation ot' the pulleys is obvious.

Secured by hinges to the under side ofthe box are arms or supports F', having weights W secured thereto by suitable cords. The object ofv these arms is to support the hinged end D of the box when the box is ready to be Adumped and prevent the end from swinging back and breaking when the box is dumped. When not in use the arms may be turned back parallel with the frame, as shown in Fig. 1.

A locking device (shown in Fig. 6) is secured at the back of platform F. The spring-bolt G enters a plate bolted or fastened to the bottom ofthe box F.

Attached to spring-boltG by means of a pin, t', is a lever, H, having a slotted plate, j, inwhichthepintenters. Thisleveris actuated from either end by cords c c, the stops KK acting as fulcra in the movement of the lever. The cords c" c extend down a sufficient distance to allow the fireman to take hold of them from the tender'.

It is obvious, of course, that l may have the frame wideenough for two, three, or more boxes to be seated therein, any one or all ot' which may be dumped in succession; and they may be of desired size. They may also be used for discharging grain or coal into cars, boats7 &c. Thol operation of my device is as follows:

L from the capstan until its platform rests on beam B, and it is then loaded. The capstan is then turned, and the ropes L, passing over the pulleys, draw up the box until it will just turn underneath the top beam, B. The arms F are then drawn forward and straightened out underneath the box and the hinged end D turneddown on them. During this time the box is held by thebolt G, and it may be re? marked that the box extends forward sufliciently to throw the center of gravity in advance of the platform F, so that when the boxis released it will fall forward. To dump the box C, catch hold of either cord c c and draw down on it.

- This will pull back bolt G and allow the box Thebox C is lowered by unwinding the ropes I ICO to fall forward on its hingesf, as shown in Fig. 3. The arms F will ai; same time fall backward, aided by the weights W, andthe fuel be discharged through the endD (actingasa chute) into the tender, which has been broughtjust beneath.

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

`1. In an elevator and dumping device, a boxhinged toaplatform moving in guidesformed by the supporting-frame, and adapted to be automatically dumped, substantially as set forth.

2. In an elevator and dumping device, as described, a frame having a box'supporting platform moving' therein, a fuelbox hinged to said platform, and means whereby the box and platforni are raised and the box automatically dumped.

3. In an elevator anddumpingdevice,aframe consisting ofthe posts A and cross-beams B B B2, in combinati'm with the supporting-pieces I, platform F, and fuel-box C, substantially as set forth.

4. In an elevator and dumping device, the combination of a vertical supporting-frame, A

B B', supports I, and platform F, moving in,
