ClNDER-CAR FOR BLAST-FURNACES.

EPECIFICATION forming part of Letters Patent No. 353,009, dated November 23, 1886.

Application filed ll'uly 14, 1886. Serial No. 208,146. (No model.)

Theinvention relates to cinder-cars adapted to convey molten or liquid cinder from a blastfurnace to a place provided for it, and has for its object the construction of a car body or ladle which may be easily and readily turned upon its axis to pour out cinder on either side of a railroad-track as far from the rail as possible, and also revolved over a pit for the removal of chilled cinder when necessary.

Cinder-cars, as ordinarily constructed, pro= vide for drawing off liquid cinder through an opening on the side of the car body or ladle, nearthe bottom thereof; but when cinder chills in the ladleit (the ladle) can only be revolved into an inverted position directly over the center of the track on which the car moves. As it would then be impossible to remove the cinder from under the car, the ladle is only partially turned over, and its contents must be dug out by breaking the mass and removing it by manual labor. It is a fact well known to furnace-men that such an operation is exceedinglylaborious and expensive, and that under certain conditionsof the working of a furnace the cinder is liable to chill frequently in the car, which necessitates the operation of digging out the contents of the car each time it .it happens that the contents of the ladle become chilled, the ladle can be revolved laterally from off the car-trucks to a prepared place to receive such a chilled mass, and its contents dropped out of the then inverted ladle spout or mouth for the flowing cinder.

at a comparatively small expenditure of labor and time.

The invention will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 represents a side elevation, partly in section; Fig. 2, an

end view showing the Worm-gear for tilting or revolving the car body or ladle; Fig. 3, a section showing the space between the ladle and its supporting-hoop. Fig. t represents aneularged sidev view of the axle-box; Fig. 5, an end view of the car and a side view of the pit, with thecar-body in an upright and in an inverted position; Fig. 6, an end View of one wall of the pit, and Fig. 7 a perspective of the detachable section of the toothed or geared track. I

Reference being had to the drawings and the letters marked thereon, A represents the car body or ladle, provided with a lining, a, of fire-bricklor other suitable material, held in position by a flanged plate, I), which is secured to angle-iron c,surrounding the top of the body, by suitable bolts, as shown. The vertical flange of the plate I) is cut away at d to form a car-body is supported in a hoop, B, separate from the body, and made in six sections, two

of which have trunnions e cast'integral there? with. The several sections of the hoop are The provided with flangesf, for securing them together by means of bolts ,9. By making the hoop B in sections the car-body can be placed in position in the hoop without removing the angleirons i, which bear against the edges of the hoop and prevent the car-body from being displaced while being tilted or inverted, and

the several joints of the hoop impart'a degree of elasticity thereto, adding strength and en and with ample space between them, the ladle is free to expand without throwing any strain on the hoop or endangeringits stability by expansion and contraction.

The trunnions e are cored out, as shown at l 2, and to each is secured a master gearwheel, C D, each of which wheels is provided on its periphery with a toothed portion, j, and plain surfaces It Z on opposite sides of the teeth, and with flanges m 12', the purpose of which will hereinafter appear. Vith the wheel a pinion, E, engages, which is mounted upon a shaft, 0, supported'in plates F G, and upon the outer end of said shaft 0 is secured a wormgear wheel, 1), which engages with a worm, q, supported in brackets r .9, formed on the plate 0, and is operated by shaft t and hand-wheel a.

It has heretofore been the practice to suspend the car body or ladle of a cinder-car by means of trunnions united to the ladle, or by trunnions attached to and forming part of a hoop, into which the ladle was closely fitted and secured thereto, without any provision to allow for theexpansion of the ladle, but, on the contrary, making the wall of the ladle a support to the hoop and trunnions. This has also been the practice in the construction of ladles for handling molten metal. In such constructions the worm-gear wheel was placed directly on the trunnion and the worm cona truck-support or pillow-block.

In handling large quantities of cinder or metal it has been found that the strain was so great as to strip the teeth from the worm-gear wheel, when the ladle would tilt backward or forward, according to the angle of inclination it was in, and frequently cause serious damage.

By interposing the master gearwheel O and the pinion E between the trunnion and the worm-gear wheel 19 the weight of the car-body and its contents is distributed over the several gear-wheelsand the stripping of the teeth from the wheel p prevented. Afurther advantage of this construction is that the car-body can be held at any angle of inclination until a portion of its contents has been discharged, when it may be changed to suit' circumstances.

In working.blast-furnaces it sometimes occurs that iron is drawn off with the cinder, and when in the car it gravitates to the bottom. By the construction and operation of my cinder-car the cinder may be poured off until the iron is reached, when the ladle may be run back or held and the car drawn to an appropriate place, where the iron may be poured off and saved without further labor.

H I represent trucks mounted upon wheels, as usual, and provided with bolsters K L, the upper surfaces of which are provided with gear or teeth 1; and tracks won opposite sides of the teeth, which correspond with the teeth and the plain' surfaces is l on the wheels 0 D, and from each side of the bolsters project ribs a, with which flanges b on the plates F G en gage. r Thesurfaces of the tracks are about prevents the spilling of its contents.

on the pitch-line of the teeth 1;, and the surfaces k Z on the wheels 0 D sustain the same relation to the pitch-line of the teeth j. By this construction the weight of the car-body is borne by the tracks 10 on the bolsters K L and the surfaces Z of the wheels 0 D, thus relieving the gearing of said weight.

Between the plates F G are wheels a, mounted upon shafts d, secured to said plates. The wheels 0 run on the tracks to and support the weight of the plates and the gearing attached thereto, and also assist in supporting the weight of the car-body and its contents. The flanges m n on the wheels 0 D engage with the outer sides, e, of the tracks w, and, in conjunction with the gearing, form the means for coupling the two -trucks through the medium of the hoop audits trunnions. The lowersides of the bolsters are provided with projections g h, which are arranged opposite to corresponding projections, i j, on the plate N of.

the trucks, and prevent the tilting of the bolster to any considerable extent when the carbody is run out on either side of the trucks.

To provide for the swinging ot' the car in adapting itself to any curves in the roadway, the bolsters are provided with hemispherical projections 70, which are seated in corresponding boxes,Z, supported by the plate N in a recess in the truck-frame P. Each box Z is seated upon an elastic cushion, m, which relieves the car containing liquid cinder of any jolts caused by rough places in the'road or matter that may have fallen on the track, and

The bolsters are also provided with flanges a, curved on their lower surfaces, to prevent any undue rocking of the car. To an extension, 0, of the flanges n are secured coupling jaws or heads 1), with an elastic cushion, q, interposed between the flange r of the coupling-jaw and the flange of the bolster. By the interposition of the cushion q the shock due to the 10- comotive striking either of the jawsp in the act of coupling is taken up by the cushion and undue strain prevented. I

0 represents laterally-removable covers for the axle-boxes, which are secured at their upper ends to the plates N by bolts and to the truck-frames]? at their lower ends, as shown. The journal-boxes s t are held in a rectangular frame, 10, open at both ends and at'its lower side.

As car-axle boxes are generally constructed the truck must be jacked up sut'ficiently high to permit the raising of the axle out of the boxes. In the manipulation of so heavy a structure as my cinder-car it becomes necessary to provide a construction that will obviate this necessity.

By the use of the axlebox shown and described the trueks. need not be raised any higher than merely to take the weight of the car off the axles, when the cover 0 may be removed and the axles run out on either or both ends of the trucks, they carrying with them the rectangular frames w, containing the journal boxes 8 t. The worn boxes are removed, new ones applied, and the axles returned to their places, when the covers are replaced and the car is again ready for use.

The carconstructed as described is operated as follows: After having been filled with cinder the car is drawn out ofthe furnace by alocomotive and taken to a suitable place for d um ping, when thecar bodyor ladleis turned to eitherside of the trucks,which act causes the car-body to travel laterally onthe bolsters while it is being tilted, and will cause the contents of the car to be discharged so far away from the track as to avoid any obstruction therefrom or danger of burning the sills on which the track is laid. Should the furnace be discharging iron with the cinder, the latter is ponredoff until the iron which has gravitated to the bottom of the ladle has been reached, when the car is moved to a suitable place and the iron poured out. When, from an abnormal condition of the furnace, it is working or discharging mucky cinderV-i. a, cinder that is very stiff and will chill rapidly in the ladle-it cannot be discharged from the ladle through a door in the side, for the reason that it chills on the surface of the lining and over the aperture controlled by the door, and forms scull sufficiently hard to prevent the discharge of the contents of the ladle when the door has been opened. This cinder will, however, pour over the top of the ladle before it becomes too thick to run, after which it must be removed by other means. To overcome this difficulty I provide pits, over which the ladle is revolved and its contents dumped ordischarged. In constructing these pits two will be sufficient, and they may be placed in any convenient position.

In Fig. 4, A represents one of the side walls of a pit, surmounted by a track, B, which corresponds with the upper surface of one of the bolsters on the car, and the opposite wall (not shown) is provided with another track. The inner ends of the tracks B are providedwith recesses 3, and both ends of the bolsters with corresponding recesses, 4, into which recesses a detachable section, 0, of track is laid and secured to the bolsters and the track by keys 5, and thereby forms a continuous track.

A car containing mucky cinder is run out of the furnace and its contents poured out of the ladle, if it has not become too thick In the latter-event the caris drawn to one of the pits, the connecting-section O inserted, and the car body or ladle run out by the worm-gear over the pit until it has made one revolution. The flanged plate-sections b are then removed from the top of the ladle, and the ladle again revolved until it-assumes an inverted position, as shown at D, when the lining of the ladle, together with the mass of chilled cinder, will fall into the pit. The ladle is then revolved back again until it assumes an upright position, such as is shown at E, when it is relined preparatory to subsequent use.

The object in revolving the ladle before ble distance away from the track, to avoid any obstruction from the cinder or bricks as they fall from the ladle. The two views D E do not show the relativepositionsof the ladles in practice, but are given merely to explain the operation of my invention.

In practicing my invention, instead of waiting for the car body or ladle which has just been dischargeduntil a new lining has been inserted, a ladle already lined may be run upon the trucks from the other pit-walls by simply detaching the section 0 and moving .on the pit-walls supporting the lined ladle.

what I claim is constructed in sections and detached from the body, substantially as described.
