of coaling such kilns by hand; and the following is declared to be a full, clear, and exact description of the invention, such as to enable any person skilled in the art of burning clay ballast to construct and usethe same.

In the constructionand erection of clayballast kilns for the production of burnt-clay ballast it has been and now is the usual practice to deliver the coal and slack upon the kiln by hand at great expense, either by first unloading it from coal-cars upon the ground by hand, and thence shoveling it upon the kiln, or by first unloading it upon the ground and allowing it to become intermixed with the clay and then delivering it upon the kiln by the action of a conveying elevator or scoop.

One method used is to deliver the coal into a hopper which feeds it into an elevator, and which thence delivers it upon a platform immediately over the breast of the kiln, .whence it is thrown upon the kiln by hand labor.

To overcome the great expense of coaling a kiln by hand and at the same time to insure a perfect and even distribution of the coal upon the kiln is the object of the invention, to fully understand which a brief description of the art of burning clay ballast will here be proper. T

Selecting a suitable place-that is, one where there is suitable clay or gumbo-for the purpose, the operator builds upon the surface of the ground an initial or core fire the desired length of material to insure a strong heat, generally of old railway ties or timbers. Then by hand a light covering of clay is placed upon the kiln from an excavation or trench running along the face of the kiln. Then coal having been previously unloaded into this trench, it is then thrown by hand upon the face of the kiln above the ditch or trench. This is called slacking the kiln. This operation is performed by hand, as before, until a ballast-excavating machine may be operated upon a railway-track running parallel with the face of the kiln, when the coal having been first unloaded'u pon the ground in the pathway of the excavating plow or scoop by hand is mixed with the excavated clay and so intermingled is carried upon the kiln by the conveyer, which carries and deposits thereon the clay or excavated material, and this operation being repeated continuously the kiln is constructed and contains when constructed a mass of clay, coal, and slack more or less intermingled, and being above and away from the initial fire it is expected that this fire from below will successively ignite the additional layers of coal and clay as they are from time to time added.

With this brief description of the art of burning clay ballast some of the many defects which exist in every kiln when it is coaled by hand will now be pointed out and how these defects by the use of this invention may be avoided.

The main purpose in the preparation of clay ballast is to insure a product of calcined clay thoroughly and evenly burned throughout the kiln and to produce this result at a minimum of expense.

The defects of ooaling a kiln by hand are,

first, the amount of coaldistribnted by hand greatest difficulty, as it is dependent upon so many circumstances, and the coal distributed upon the kiln being quickly covered by the next and succeeding deposits of clay is at once hidden from the operator, however careful he may be, and if the coal is deposited upon the ground first by hand and then intermingled with the clay by the operation of the excavating-machine its even admixture and distribution is but a matter of looseconjecture and the degree or evenness of the admixture cannot be really known until the kiln is burned out and opened, when, if there has been any uneven or unequal admixture of the coal and clay, it may be then seen in the inferior ballast product. The defect in the admixture cannot then of course be remedied, the loss to the operator being complete. Again, if from any cause it becomes necessary, as it frequently does, to reslack or recoal the kiln during the progress of the workit is practically impossible without great expense to do this by hand, asthe condition of the kiln at the place where the coal is required is beyond remedy and reach of the operator attempting to coal by hand. There is, it is believed, not now in existence any practical method or way of recoaling a kiln of ballast by hand without great and unnecessary. expense. Therefore in practice as the art is worked at the present time great quantities of inferior and partially-burned and unevenly-prepared ballast exist in every kiln, and the ballast product at present produced is generally of an unevenly-burned quality and low grade, resulting from the great uncertainty experienced in the coaling of kilns by hand,

To overcome the foregoing and other defects in present processes and methods of burning clay ballast is the object of this invention set forth in the following specification. This object is attained by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view of the machine and the attached car to be unloaded, omitting the motive power. Fig. 2 is a top view omitting the motive power. Fig. 3 is an end view of the machine, omitting the motive power and slack or coal car.

Similar lettersrefer to similar parts throughout the several views.

The cars are designated by G and F, the former having mounted upon it a suitable engine to operate the drum 0 and drum D, the car F carrying the load of coal to be distributed upon the kiln. Extending over the car F are booms K K, suitably braced to support the weight of the loaded scoop. A. Adapted and constructed to travel upon booms K K is a trolley E, carrying a grooved sheave f, loosely mounted upon an axle midway between the'sides of the trolley and the wheels 2' t'. A Winding and unwinding cable I), drawn and released by the winding-d rum 0, passes upward and over a sheave g, and thence oversheave f, to where it is connected to the bail a of the scoop A. The sheave, 7c in a hanger below tne trolley E, besides being a guide for the cable 19, operates in connection with this cable to draw the trolley forward, so that the scoop A may more readily assume its position over the coal-car to be unloaded and in position for reloading.

Spring-latch h, with the spur h, is the means to facilitate the unloading and dumping of the scoop-load into the hopper B. A cable 0, attaohed to the upper rear end of the scoop A, thence passing upward over sheave e, mounted upon a shaft between the parallel booms K K, thence backward over a loosely-mounted double-grooved pulley g, and thence to the winding-drum D, constitutes the means whereby the scoop A is drawn backward into position for reloading after it has emptied its load into hopper B. To facilitate the downward and backward movement of the scoop and its speedier return to a position immediately over the coal-car, booms K K are inclined upward and away from the hopper and are secured to upright posts g g. Between the posts g g a frame, with bearings in its upper ends, supports the shaft carrying the double-grooved sheave 9. Over this double-grooved sheave, itwill be understood,pass both' the cables b and c, the sheave being in two sections independent of each other. A hopper B, with a slanting discharge-pipe L, having a grating or screen at its lower end, furnishes an outlet from the hopper into the horizontal pipe I, from the latter of which the coal is finally discharged upon the kiln. A receiver H shown in the drawings; but this may be omitted where the coal is free from lumps and other obstructions likely to choke the discharge-pipe. The screen M at the lower end of the pipe L prevents any large pieces Of Coal and other materials from obstructing the even flow of the coal from the hopper down and through the dischargepipe I. The discharge-pipe I supplied at its outer end with a concave deflector O, which may be readily adjusted or turned upon the end of the discharge-pipe I by means of the collar 0.

After the coal has been deposited into the hopper B and thence downward into the dischargerpipe Iit comes in contact withan airblast furnished by means of a blower N. For this purpose a centrifugal blower is preferred; but the invention is not limited to any precise form of blower. In practice it will be an advantage to employ a flexible dischargepipe, s0. that the coal may be distributed at any desired angle; but if this be employed the deflector can then be dispensed with. To suspend and adjust the position of the discharge-pipe I, a transverse boom P may be employed, and to facilitate the'speedyadjust'ment of the discharge-pipe I a pulleyl and cable 19 may be employed to. advantage. The cable 13 is wound around a drum 0 within reach of the operator.

The drum-and-clutch mechanism employed to wind and unwind the cables supporting and drawing the scoop A may be of any approved kind in well-known use. The motive power also used to operate the drums and to drive the blower or fan may be connected up to the car by any suitable sprocket-gear or hther mechanism by which the car, may be moved upon the track.

The mode of operation of this machine-is as follows: Adapted to travel upon a railway-track adjacent and parallel to a clayballast kiln in course of construction is a flatcar carrying the motive power and frame supporting the scoop and fan. The booms proj ectin gout longitudinally reach over a load ed coal-car filled with the necessary coal or slack to be distributed upon the kiln. Power being now applied to the drum D by means of cable 0, the scoop A is drawn into a position over the coal-car and there dropped with its open face downward into the coal. Power is then applied to the drum 0, and by the operation of this mechanism and that of the draftcable I) the scoop is drawn forward, filled, and carried upward toward the trolley E and, coming in contact with the trolley and e the cable 0 being released or loosened, is

carried upward, with the trolley, over the inclined booms K K' to its dumping position over the hopper B. Cablecis then tightened, cable 12 is released, and the scoop A turns upon its pivoted bail and discharges its load into the hopper B. The coal from the hopper naturally descends through the pipe L, is

screened by the grating M, and flows on into the discharge-pipe I, where it comes in contact with the air-blast supplied by the fan or blower N, and by this means the coal is blown and distributed upon any part of the kiln evenly, as desired by the operator. By means of the deflector O the contents of the hopper as said content-s pass out of the end of the discharge-pipe I may be diverted in any desired direction by changing the location of the deflector.

It is to be understood that this invention is not restricted to the particular construction shown and described, since it is obvious that various changes in the construction might be made by one skilled in the art without departing from the spirit of the invention.
