SPECIFICATION forming part of Letters Patent No. 369,503, dated September 6, 1887.

Application filed February 9, 1887.

T 0 all whom it may concern.-

Be it known that I, FRED H. DANIELS, a citizen of the United States, residing at \Vorcester, in the county of I'Vorcester and State of Massachusetts, have invented certain new and useful Improveinentsin Rollingldill Transfer and Charging Apparatus, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

The objects of this my present invention are, first, to provide a practical and cfficicnt mechanism for mechanically transferring billets or bars of metal from the. discharge-table of a rolling-mill or other delivery to a desig nated place of deposit; second, to provide means for mechanically transferring billets or bars of metal from a delivery-bed and automatically charging the same into a heatingfurnace; third, to provide means for separating, shearing, or cutting up bars or billets as they are delivered from a rolling-mill into sections of desired length, and automatically transferring; and delivering the sections into a heating-furnace, or depositing them at such other place of deposit as required; fourth, to provide a billet-conveyor or transferring mechanism having intermediate delivery passes and adjustable gates at intervals along the transfer-way to aii'ord facilities whereby the billets or bars canbe delivered at several different positions; fifth, to afford a charging mechanism with a system of rolls or adjacent advancing surfaceswhich, when the billet is deposited between them, act to impel the billet longitudinally forward to the position of discharge; sixth, to provide a mechanism forlongitudinally charging billets or bars, consisting or a system of convergent rolls supported by upright shafts, between the advancing sur' faces of which the billet is gripped, combined with devices for guiding and directing the bar into the mouth of the heating-furnace; seventh, to afford means for the economical production of wire rod or other small shapes from blooms by reducing the bloomin rolls to a billet or partially-formed product, cutting the same to convenient length, and mechanically transferring and charging said billetsections intoa furnace for reheating, and then Serial No. 227.004. (N0 model.)

continuing their reduction to a finished pro duct by further passage through reducingrolls or train of rolls; eighth, to provide an apparatus or plant for rolling bars or billets from blooms, cutting the billets or partiallyreduced product into sections, and automatically transferring and charging the same into a reheating-furnace, and then reducing said billets by rolling into wire rods and reeling the finished product, the operation being performed by direct or continuous process. These objects I attain by mechanism the nature, construction, and operation of which are illus trated in the accompanying drawings, and explaincd in the following description, the particular subject-matter claimed being hereinafter definitely specified.

In the drawings, Figure l is a plan view illustrating the nature of my improved mechanism for cutting up, transferring, and automatically charging metal bars or billets. Fig. 2 is a transverse section at the position of line to w on Fig. 1, looking in the direction indicated by the arrow. Fig. 3 is a longitudinal section at the position of line at m on Fig. 1. Fig. 4 is a plan view showing myinvention as employed in a plant for reducing and cutting up blooms into billets, automatically transferring the} billets into a reheating-furnace. and reducing the same to wire rods. Fig. 5 is a view of a portion of a similar plan, showing a modified arrangement of the rolls in the billet-forming mill.

In accord with the practice contemplated in my present invention, the metal is primarily heated in the form of blooms of any convenient size, which blooms are then rolled down or reduced into billet-bars of, say, about one inch square (more or less) by a series of reducing passes in properlyarranged rolling apparatus. The bars are delivered longitudinally onto a roller-bed or receiving-table as they come from the billet-forming apparatus. In connection with this roller bed or table, I arrange means for cutting the bars into billets of convenient length, which preferably consists of rotary shears or cutters disposed at the head and foot of the receiving-table, and having suitable clutches connected with their driving mechanism for throwing the cutters into and out of action at the required intervals of time. These clutches may, if desired, be

arranged for automatic action to operate when a given length of billet has been delivered from a rolling-mill, or be worked by hand, if preferred. At one side of the roller-bed, and extending laterally therefrom, I arrange a series of rails, tracks, or transfer-ways, and above said rails, and running parallel therewith, a series of chains or belts operated by suitable sprockets or driving-pulleys. Said chain belts are provided with hooks, lugs, or prongs that engage the billet and drag it laterallyfrom the delivery-bed along the transfer-way until it reaches a position Where it can drop away from the chain. Openings or passway-spaces are provided at intervals in the rails of the transfer-way at such positions as it is desired to deliver the billets, and movable gates are combined with the rails for closing said openings, so that the billets will pass across them, or for opening the passways to permit the billets to fall through the space.

Combined with the transfer-way and means for moving the billet along the same at the position or positions of delivery I arrange charging mechanism provided with oppositelyconverging advancing surfaces, between which the billet is thrown or falls by gravity, which surfaces, acting by gripping and friction, project the billet forward as required. This charging mechanism is preferably a series of rolls arranged in pairs, and made of conical form or upwardly tapered, fixed to or running on upright axial shafts, and rotated by power driving mechanism, so that when the billet falls from the transfer-way it will be immediately caught or gripped between the roll-surfaces, and thereby projected forward into the furnace by rotative action of the rolls. Guiderolls or guide-plates are provided for support ing and directing the billet as required to properly project it into the furnace.

The mechanism for transferring, shearing, and charging the billets is provided with suit able driving-shafts and gears, and a motor or engine is provided for imparting the operative power and motion. Suitable clutches are arranged in connection with the driving-shafts and gearing for throwing the different parts of the mechanism into and out of action.

The transfer-rails may extend any required distance, and any desired number of delivery intervals and gates may be employed, and the transfer way may embrace any number of tracks or supporting-rails and carriers or belts in the series, according to the length of the billets which it is desired to handle.

In referring to parts, A indicates the bed or table onto which the billets are delivered from the billet-forming mill B. Said table is pref erably provided with a series of rolls, a, mounted in suitable bearings to run loose, so that the billet will run forward upon the table without undue friction.

0 indicates a shearing device located near the head of the table for severing the billet into sections, and 0 indicates a similar shear rear end of the tracks.

at the foot of the table for cutting off the crop ends of the billets.

D indicates a driving-shaft operated by the engine E, and D a shaft for transmitting power and motion to the second shear devices. The respective shears, G and G, are provided with suitable operating-gearing, G and with clutches O for throwing them into and out of action. The shaft D is provided with suitable connecting-gears, as at d d.

' Findicates the laterally-extended rails'or tracks upon which the billets are supported and'transferred from the roller-bed A. Said rails are preferably arranged in pairs, as indicated, the pairs being disposed at such intervals apart as will suitably support the billets from sagging. In the present instance four tracks or pairs of rails are employed, the apparatus being designed for transferring billets of about twenty-five feet length, (more or less,) or such billets as are employed for rolling into wire rods. Above each of the tracks 'or pairs of rails is arranged an endless traveling chain belt, G, supported by a guide-pulley, g, at the front of the roller-bed, and by a drivingsprocket, h, fixed to an overhanging operating-shaft, H, at or near the rear end of the transfer-tracks. Said shaft H carries the sprockets or pulleys for the entire series of chain belts, which are all simultaneously and uniformly operated thereby. The shaft H is connected by suitable gearing and the upright shaft H" with the driving-shaft D, which latter receives motion from the engine E, and a clutch, H", is provided for throwing the chain mechanism into and out of action. The traveling chains or belts G are provided with lugs, hooks, or projecting fingers G, which engage the billet and move it along the tracks F, the said fingers on the several, belts being at correspondingv position, so as to move the billet parallel. The shaft H is supported by hangers H from an overhead beam or frame, H, so as to allow the billets to pass off the The rear end of the tracks are preferably inclined downward, as indicated at F so that the billets can be delivered therefrom and piled onto a car or onto the floor by sliding them down the incline. The portion F of the track is preferably made to swing up and down for delivering the billets at any desired height from the floor. At corresponding intervals along the several tracks passways or openings are formed, as at f, and suitable gates, f, are provided for closing said passways when it is desired to transfer the billets beyond the position of the same. In the present instance the gates are made as sliding bars, and are operated by arms connected with a rocker-shaft, f which is provided with a hand-lever, f, by means of which any series of the gates. can be opened and closed. 7 l

The tracks F are supported on beams or girders J, in connection with frames or standards J, near the passways f.

I indicates the series of rolls for charging the billets into the furnace. Said rolls are preferably mounted on upright shafts rotated by means of suitable gearing from an operating-shaft, I, which in turn is operated by the driving-shaft D. Clutches I are provided for throwing the roll mechanism into and out of action. The rolls I are disposed in pairs, one, two, or more pairs being employed, as preferred. In the present instanceI have shown a series of four pairs in each of the charging devices, two pairs being geared for operation by the shaft 1 and two pairs arranged to run loose or to serve simply as guide-rolls, power being applied only to the geared pairs, as indicated in Fig. 3. It is obvious, however, that all of the pairs of rolls I might be geared and operated from the shaft, if preferred. The rolls I serve to grip the bar between advancing surfaces as it falls from the tracks F through the passways f into the space between the rolls. The rolls I can be made either as shown in the right-hand series, Fig. 2, or in the left-hand series. In one case the rolls are made conical or tapering upward to give oppositelyconvergent surfaces, so that the billet will wedge between the surfaces as it is dropped between the rolls. In this instance the rolls are supported in stationary bearings and geared together in pairs to cause the surfaces to move with uniform velocity. In the case of the rolls illustrated at the left-hand series, Fig. 2, the rolls are shown of cylindrical form, and one roll of each pair is mounted to run loose on a movable axis or swinging shaft that is fixed to a rockershaft, K, which latter shaft is furnished with a lever, K, connected with the piston of a hydraulic cylinder, K so that the rolls can be moved to or from each other for gripping and releasing the billet between the rollsurfaces by actionof the by draulic piston under control of the valve V and its operatinglever V, which valve and valve-operating lever may be placed at any convenient position adjacent to or at a distance from the cylinder, suitable pipe-connections'being provided for conducting the water from the valves to the cylinder.

L indicates horizontal rolls that are provided for supporting the bar and preventing it from dropping too far down between the rolls I.

in and m indicate guide-rolls arranged adjacent to the front of the furnace M. The roll m serves to support the billet from running on the bottom of the furnace, and the roll m serves to hold down the rear end of the billet from tilting up by preponderance of its for ward extremity as it runs into the furnace. Said rolls mm are preferably made adj nstable up and down in their supporting-frame, and are operated by suitable sprocket-wheels and chains, m and drivinggearing m in connection with operating-shaft I.

n and n indicate guide-plates which serve to assist in directing the billets into the furnace.

In the present instance, as illustrated by Figs. 1, 2, and 3, I have shown the transferringways as having three positions of delivery via, the passways f for first and second chargers and at the end of the track. It will be understood, however, that the apparatus can be constructed with a greater or less number of positions for delivery, if required, without departure from the nature of the invention. It is also obvious that a greater or less number of tracks or ways F and carrier-belts G may be used accordingly as long or short billets are to be handled.

The transfer and charging apparatus arranged as herein described could be employed for conveying and feeding hot bars into the passes of rolling-mills in lieu of into the furnace. In such event the rolling-mill would be located in line with the charging-way-as, for instance, at the position in Fig. 1.

In Figs. 4 and 5 I have illustrated my invention as employed in a plant for making,

transferring, and reducing billets complete from blooms into finished wire rods.

Ndenotes the furnaceforheating the blooms to be reduced in the billet-forming mill B, which mill maybe constructed as indicated in Fig. 4, and as described in detail in my previous application for Letters Patent, Serial No. 225,995, or be made with a series of rolls disposed to operate in continuous order, or in other suitable manner. From the finai pass of the rolling-mill B the billets run out direct or through the guide Z) onto the roller-bed A, and are there cut up by shear C and transferred and charged by the mechanism which is above described, as fast as the billetsections are formed, into the furnace M, for reheating or elevating the temperature to proper degree for the further reduction.

P indicates a continuous rod-rolling mill or rodreducing train, which receives the billets from the furnace M and reduces them to wire rods, which rods are automatically reeled, coiled, or wound up, alternately, by the reeling apparatus at R R, a suitable switch device, S, being arranged for directing the rods alternately to the respective reels.

T indicates a chute for receiving billets in case any disarrangement occurs in the transferring or charging mechanisms, or in the event of a surplus of billets being run from the mill B in excess of what can be conveniently charged into the'furnace M.

B indicates the engine for operating the mill B.

In Fig. 5 I have illustrated a modification of the billet-forming mill, wherein the rolls are arranged operating in continuous order instead of by back-and-forth passes.
