SPECIFICATION iorming part of Letters Patent No. 366,917, dated July 19, 1887.

Application filed Deccmber IG, 18h51. Renewed June 17, ISST.

To all whom it may concern:

Be it known that I, GEORGE E. BLAINE, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new anduseful Improvements in Dumping Cars; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and t-o the letters of reference marked thereon, which form a part of this specifica` tion.

My invention relates to dumping-cars, and has for its object to provide an improved construction ofthe ear, whereby it can be loaded with the same or different contents, which will be entirely separate from each other, and to also provide an improved mechanism for dumping the two contents on opposite sides of the track, which will be performed in a rapid and effectual manner, with a minimum expenditure of power, a saving in time, and a certainty of correct action, the parts being so arranged and combined as to be entirely under the control of the operator at any and all times, and can be corrected, reversed, or altered at any desired period.

To accomplish the above-mentioned objects I have constructed, arranged, and combined the parts and mechanism herein shown, and of which my invention consists, all of which will be fully and aceuratel y described hereinafter,and specifically pointed ont in the claims.

Referring to the drawings, Figure l is a perspective View of my improved dumpingcar. Fig. 2 is an end elevation showing said car in an upright positionwhen loaded and not tilted, and also illustrating the end having the operating or dumping mechanism. Fig. 3 is an end elevation of the other end of the car. Fig. 4t is an end view ofthe car when dumped. Fig. 5 is a side elevation ofthe car-body, showing the manner of hinging it to the drawframe and the bifurcated arms P P. Fig. 6 is an enlarged detail view showing the latch.

Like letters of reference indicate corresponding parts in all the figures.

Referring to the drawings, A represents the body ofthe car having hinged sides A, mounted Serial No, ilfll. (No model.)

at their tops ou hinges a, of ordinary construction, which permit thc doors to swing freely when not controlled by mechanism, to be hereinafter described.

B are the side beams or sills ofthe body, and C the end beams. rlhe remaining portion of the body, except as hereinafter described, is of ordinary construction. On the side beams, B, are clips, (not shown,) which serve as guides for vertical latch-bars c, of which there are two for each hinged side or flap, and they serve to prevent said doors from tilting or swinging outward, except at the desired time. At their lower extremities these latch-bars are pivoted in the forked ends a ofthe levers D, and said `levers are pivoted on hangers a, depending from thesills B, and are provided with sliding weights E on their inner ends, which normally serve to hold the latch-bars in their highest position.

The lower or draw frame is composed ofthe longitudinal rcach-bars F Fand holsters FF, and to this frame are attached the bumpers d d, and the ends of this frame extend sufficiently beyond the car-body to form a platform, upon which the operator stands.

Projecting through the bolsters is the kingbolt, (not shown,) by means of which the body is connected with the truck, twin pivot-plates or bearing-guides fj" being secured, respectively, to the bolsterand the cross-beam G ofthe truck.

On the ends of the reach-bars F F are suitably bolted and secured the two cross-beams H, upon each of which are placed the journalbearings for the main operating-shaft I, which extends from platform to platform. Upon each end of this shaft is mounted the gear or worm wheel 71., which is held rigidly on shaft and securely in place by the bearings g and z', one of which is not shown. Immediately behind and adjacent to the bearings is arranged the double flangewheels J, rigidly secured to said shaft at each end. The worm-wheel h on end of said shaft is engaged by worm-wheelj,

(not shown,) mounted on the upright shaft K,

which is journaled in a bearing, la, secured ou the platform of the car, said bearing serving as a boxing for the small worm-wheelj. The upright shaft terminates iu the hand-wheel L,

IOO

of each other, as will be hereinafter described.

The inner edges of the sills of each halfcar are hinged to the draw-frame of the truck, and are provided with the upright standards M M at each end, said standards being substantiallyT braced by rods e e, secured to the sills and standards. These standards, taken in connection with the worm-wheel mechanism and shaft, serve to dump the car in the following manner:

Vhen the hand-wheel L is turned,thc wormwheel j engages the gear-wheel h, which is rigidly secured to said shaft. This motion revolves the shaft I, and consequently the double iiange-wheels J. Now, to the hub of this manner to standards M, as shown.

iiange-wheel is secured the one end of the chains m, the other ends passing over the pulleys N, secured in studs o on the ends of the standards M, and are fastened in any suitable Thus they operator having rotated the shaft I, it causes the chains to be unwound from around the double fiange-whecls J-that is, if the car is to be dumped-and thus by weight of its load the car gradually is allowed to obey the force of gravity, as only one side is hinged to the draw-frame, because, as will be evident, as the wheel J allows the chain to be released,nothing prevents the car from obeying the law vof gravity. When the'body of the car A reaches a certain incline, vit causes the latchet c to remove automatically out of the Way of the hinged iiaps A A on the side of the car at the proper time to allow the load to slide off. When the car-body begins to tilt,v the latchets are automatically removed by the weighted levers and the auxiliary devices hereinbefore described, but which I do not claim, as they form part of the subject-matter of a previous application; but instead of using the arc-shaped holsters, as heretofore, to prevent the car from going over too far, I-employ thebifurcated horizontally-extending bars I), upon which the levers rest when the car has reached its tilting limit. NVhen the half-cars arein upright position, they can be secured together tightly by means ofthe stay hooks or fingers R It, pivoted on standards M', and the pins or catches r on standards m, as shown in Fig. l. When the car has been unloaded, the operator can, by reversion of the hand-wheel, wind the chains m back around the flange-wheels, and thus re? turn the car-body to its normal or upright position on its track and ready to be again loaded.

My improved dumping-car is particularly designed to be used in the construction of railroads, and the transportation and dumping of rock, dirt, and so forth, which are used for ballast and4 lling purposes for the sides of the roads.

There are many obvious advantages whichy accrue from the car being longitudinally divided into two halfcars and provided with the dumping mechanism, a few of which are hereinafter enumerated.

Heretofore when dumpingcars were used for the above-mentioned purposes the load dumped on the side of the track was so large, owing to the size of the car, that there was an vadditional expense incurred by the buildersfor shoveling and distributing the earth, rock, 86o., proportionately along the track, as the load accumulated in one vast heap, and thus required to be distributed, whereas with my construction, which makes the load the same in bulk, it is so' divided that it can be unloaded upon both sides of the track at the same time in proper quantity, which will obviate the necessity of any distribution Whatever.

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

l. rIhe combination of the half-sections having hinged fiaps or sides with the chains m, the flange-wheels, the worm-wheels, and the shaft, as described.

2. The combination of the car-body divided longitudinally in two parts with hangings, standards, hingedl flaps, the chains, Hangewheels, worm-wheels, and shafts, as set forth.

3. The combination of the car-body longitudinally divided into two sections or compartments, each section being hinged or pivoted centrally to the reach-bars of the drawframe, and having hinged fiaps or sides, with the automatically-operated latches, the bifurcated arms, `and dumping mechanism, as described.

4. The car-body longitudinally divided in two compartments or half-cars, and having hinged flaps or sides, with the automaticallyoperated latches and the bifurcated arms P, as set forth.

5. The combination, in a longitudinallydivided dump-car adapted to dump each side of the track, of the dumping gear mechanism, the vertical central standards, chains m, and the locking-hook r, as described.

In testimony that I claim the foregoing as my own I hereto aliix my signature in presence of two witnesses.
