UNrrED STATESA PATENT @trices CHRISTOPHER LEWIS, OF OOLUMBUSOHIO.

FEED DEVICE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 247,931, dated October 4, 1881.

Application led July 27, 188,1. (No model.)

To all Iwhom it may concern -Be it known that I, CHRISTOPHER Lewis, of Columbus, in the county of Franklin and State of Ohio, have invented a new and Improved Feeder for `Continuous Rolling-Mills; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanyingdrawings, forming part of this specification, in Which- Figure 1 is a plan View. Fig. 2 is a side elevation, looking in the direction of the arrow fr.

In an application for a patent filed by me January 12, 1881, I described a novel construction of rolling-mill for rolling bars of iron or steel, railroad-rails, and the like, in which I contemplated the continuons passage of the rail or bar through the entire series of rolls,

- each alternate pair of which had a reversed movement, so that the rail, after passing through one pair of rolls, was received on a buggy, which was made laterally adjustable to the next pair of rolls between which the rail was entered and rolled, and upon the delivery side of which pair of rolls another laterally-adjusta,` ble buggy was made to receive the rail and transfer it to the next, my object being to dispense with the great number of workmen ordinarily employed for this work, and to secure a rapid, continuous, and practically automatic action.

My present invention relates to the construction and arrangement of afeeder for such rollin gmill, or a device for transferring the bloom to the furnace, and also from the furnace to the first pair of rolls; and to this end it consists, principally, in one or more buggies pivoted at one end in line with the first pair of rolls, and having its other end arranged to swing upon a curved track, so that it may be i, swung out to the line in which the bloom is withdrawn from the furnace and then returned to the line of feed to the rolls.

The invention also consists in the combination, with these swinging` buggies, of shafts, clutches, drums, and chains for operating them, and also in the combination of the supportingrollers of these buggies with devices for rotating them to advance the bloom whenever the vbuggy is thrown into line with the rolls, all as hereinafter more fully described.

In the drawings, A represents the main shaft, which act-uates the series of rolls, as described in my application referred to.

B represents the. first of these series of rolls. Upon the feed side of this pair of rolls, and in line therewitlnis one, two, or more swinging buggies, D D.

E is a drive-shaft for operating the movable buggies, which drive-shaft is arranged parallel to the line of feed to the first roll and at right angles tothe main shaft A, to which latter it is connected through a bevel-gear, and fromV which main shaft it derives its motion. The stationary buggy has one or more of its supporting-rollers driven by the shaft E, so that a bloom delivered upon the same will be positively and automatically fed between the lirst pair of rolls.

D is the first of the swinging buggies. This is mounted at one end upon a vertical pivot, arranged at c in the line of feed to the rolls, and-at its other end it is provided with wheels that travel upon the curved track d, so that the said buggy may be turned from a position more or less at right angle to the line of feed to receive the bloom from the furnace, and be then turned into alignment with the stationary buggy C and the rolls to advance the bloom to the said rolls. To give these movements to this buggy there are placed upon the shaft E three loose drums, F F F2, which are arranged to be connected with the shaft for rigid revolution by frictionclutches f j" f2. One of these drums, F, connects with the free end of the buggy D on one side by a chain, g, and serves to pull the buggy into alignment with the rolls. Another one ofthe drums, F2, connects with the free end of the buggy on the other side by a chain, g2, and serves to pull the buggy into a right-angular position to receive the bloom from the furn ace N o. l, and the other drum, F', on this shaft connects with a chain, g', which lies directly over the buggy when in a right-angular position to the line of feed, and connects with the tongs for holding the bloom, and by which the bloom is drawn from the furnace No. l onto the buggy D, when the latter is in the position shown in dotted lines.

On the shaft E is a worm, G, and clutch H, rotated thereby, while a corresponding clutch, I, is arranged upon the extension of one of the a stationary bugg O, and

ICQ

journals ofthe bugg 7-rollers, so that when the buggy is thrown into line with the rolls B the clutch I of this buggy is projected against the clutch H, and the feed-rollerof the buggy being rotated thereby, the bloom resting on the same is advanced to the stationary buggy, and passes thence between the rolls from the inlinence of clutches H3 I3 and worm G3.

A second movable bugg i, and also a third and fourth, may be arranged to work in connection with a greater number of furnaces. I have shown a second buggy, D', which works the second furnace, which latter is located upon the opposite side of the shaft E from the first furnace that supplies buggy D. This second bugghY is pivoted at one end in the line of the rst stationary buggy and the rolls, and swings on a circular track to the right of the line of feed. For operating it a counter-shaft, E', is laid parallel to E, and connected therewith through a short shaft, H2, and bevel-gears. Upon this counter-shaft are arranged for this buggy the three drums, clutches, and frictioni feed in a manner similar to the first swinging buggy, which parts I have not shown in the drawings.

By means ot' this invention the feeding of the steel from the furnace to the continuous mill is effected mechanically7 and a great numberof men employed for this purpose dispensed with.

Having thus described my invention, what I claim as new is- 1. The combination, with the main shaft A ot' a rolling-mill, of a right-angular shaft, E, equipped with drums, chains, and clutches, as described, and one or more swinging bugges mounted at one end upon a vert-ical pivot in the line of feed, and swinging upon a track at the other end, so as to receive the bloom when in one position, and then be thrown into alignment with the rolls, as described.

2. The combination, with the irst rolls ofa rolling-mill, of a vertically-pivoted buggy, mechanism for turning it horizontally, and a coupling for rotating the feed-roller of the buggy when in alignment with the direction of feed for the advance of the bloom, as described.

3. The combination, with the stationary buggy G and the pivoted buggy D, ot' the shaft E, having three sets of drums and clutches and chains connecting with thebuggy,as described.

4. The combination, with the pivoted and swinging buggy D and the shaft E, with its triple sets ot' drums and clutches, of the second pivoted bugg i, D', arranged to swing in the opposite direction, and a counter-shaft, E, provided with a triplicate set ot' drums and clutches, and connected with the shaft E by a short right-angular shaft and bevel-wheels, as described.

CHRISTOPHER LEWIS.
