METHOD OF AND APPARATUS FOR PRODUClNG RAILWAY-BALLAST FROM FURNACE-SLAG.

SPECIFICATION forming part of Letters Patent N 0. 465,572, dated December 22, 1891.

Application filed April 20, 1891. fierial No. 389,716- (No model.)

To aZZ whom it may concern;

Be it known that I, JOHN IV. DIEBOLD, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Methods of and Apparatus for Producing Railway-Ballast from Furnace-Slag; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which-it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, in which Figure 1 indicates a side elevation of my improved device for preparing blast-furnace slag for utilization as railway-ballast. Fig. 2 is a partial end elevation of same. Fig. 3 is an enlarged plan View of roller journaled in large link of chain. Fig. i is a side"vie\'v of same. Fig. 5 is a detail perspective view of one of the molds. Fig. G,Sheet1, is a side sectional elevation of breaking-plate and incline.

My invention relates to improvements in the method of and apparatus for the production of railway -ballast from blast -furnace slag, the object of my invention being to prepare from said slag a serviceable and durable railway-ballast at a cost that will warrant the use of the same in preference to other mate rial that may be used for such purpose, and this I have obtained by the method and apparatus used therein, which method, broadly stated, consists in filling slowly-moving molds with blast-furnace slag from a modoc, or in any suitable manner, and after permitting said slag to cool somewhat in said molds to discharge the same upon a metal plate or other hard substance and reduce the sameto fragments, and then convey said broken slag to an annealing-oven.

In the drawings I show an apparatus adapted to the application of said method. Said apparatus consists of a series of molds suitably secured upon a pair of endless chains operating over sprocket-wheels placed a suitable distance apart, according to the width of said molds. The upper pair of said Wheels is elevated a very considerable distance above the plane of the lower pair, whereby the chains operating over the same are maintained at an angle of almost forty-five degrees and elevating the forward end, where the slag is discharged from said mold, a distance sufficieut to break said slag into fragments upon a metal plate suitably located at such point.

I will now specifically describe my invention, reference being had to the accompanying drawings, forming part hereof, in which like letters indicate like parts wherever they occur.

Referring to said drawings, a a .are uprights at any required distance apart, according to the width of the apparatus. 1') b are similar uprights at the opposite end of the apparatus.

0 c are endless chains, one at either side said apparatus and adapted to operate over sprocket-wheels (Z cl cl (1, which are suitably secured, respectively, on the shaftsf and respectively. Said shafts f g are respectively suitably journaled in the uprights a a b b, respectively, the shaft 9 being considerably above the plane of said shaft f, where- '7 5 by said chains are maintained, as shown in Fig. 1, preferably at an angle instead of horizontal. Atiutervals in said chains, depending upon the length of the molds, are placed links h h h, 820., considerably larger than the remaining links of said chains. Between said links 7L h and suitably journaled therein are a corresponding number of rollers 'i t t, &c., which are adapted to pass between the sections of said sprocket-wheels d d and travel along the eyebeams 71? 7c, the ends, respectively, of which are suitably secured upon the uprights at either end, respectively, of said device, as shown in Fig. 1.

Z Z Z, 650., are series of transverse bars connecting said chains, being preferably formed of angle-iron suitably secured upon the upper side of said links h h h, and having near the ends thereof lugs m m, the.

n n n, &c., are a number of molds adapted to contain molten slag, the forward end of one and the rear end of the next succeeding one of said series of molds being pivotally connected to said bars Z Z Z by the lugs 0 o 0 and the armsp p p, &c., upon the forward mo and rear ends, respectively, of said molds, the lugs 0 0 being formed or secured upon the lower forward end of said molds near the sides thereof and the arms 1) 1) being pivotally secured in the bearings q g at either side the rear of the same, as shown in Fig. 1, said arms being of sufficient length to maintain said molds in a horizontal position, as shown in Fig. 1, notwithstanding the chains which carry said molds are inclined at an angle. The rear of said molds is provided with slots or gates 07/72 to enable the molten slag to pour from the forward to the next succeeding mold, thereby avoiding the danger of overflowing either said molds. Suitably secured upon the sides of said molds are rollers 'r T, which are adapted to travelon the beams s s in the return passage.

25 is a metal plate, preferably the bottom of a bin, placed beneath the elevated end of said device in such position that the solidified slag when, discharged from said molds drops thereon and is reduced to fragments, and is permitted to slide down the incline u, connected with said plate, into an annealing-oven (not shown) at or near the bottom of said incline.

The operation of my device is as follows: Blast-furnace slag, being carried by a modoc or otherwise suitably conveyed from a blast furnace, (not shown,) is permitted to flow into said molds at the lower end of said device.

Power being applied to said device, said molds in a liquid condition to slowly-moving molds, which permitit to cool and solidify, and discharging it from said molds in a solid condition upon a metal plate beneath, whereby it is reduced to fragments and subsequently annealing such fragments.

2. The combination of a pair of endless chains connected by a number of transverse bars provided with lugs, a pair of sprocket- Wheels suitably secured upon shafts journaled in the frame of said apparatus at either end thereof, one pair of said wheels being so elevated above the plane of the other pair as to incline said chains at an angle, and a series of molds adapted to be carried by said chains, the forward end of said molds being pivotally connected to the lugs on one of said transverse bars by a short arm, the rear ends being similarly connected to the next succeeding bar by an arm of greater length, whereby said molds are enabled to maintain a horizontal position, substantially as and for the purpose set forth.

3. In a ballast-producing device, substantially as described, the combination of a pair of endless chains adapted to operate over sprocket-wheels at either end of said device, the rear pair of said wheels being elevated, whereby the chains operating over the same are inclined at an angle, said chains being connected by transverse bars provided with lugs and having suitably journaled at intervals in the links of the same a number of rollers, and a series of molds pivotally connected to said bars and adapted to be carried by said chains, and a metal plate located beneath the elevated end of said device, substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing I hereunto affix my signature this 9th day of April, A. D. 1891.

- JOHN W'. DIEBOLD. [L. s]

In presence of J NO. H. Ronny, W. H. LEMON.
