ITo (din-7mm it mag concern:

Be it known that -I, ALEXANDER IIoovEN and \VILLIAM IIENRY ADLE, of Norristowmin the county of Montgomery andState of Pennsylvania, have invented certain new and useful Improvements in a Machine for Rollin g Iron or other metals and we dohcreby declare that the i'ollowing'is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appcrtains to make and use thesame, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

.l igure 1 is a top orplan view of the machine.

- by three rolls throughout the process of rollin g, all as hereinafter more fully set forth.

-In the drawings, A marks the bed-plate of the machine, and A the frame in which the operative parts are'supported. In this frame are adiustably fixed the journal-boxcsof the rolls B U I) E F G ll I J K, whose journals I) c d of g h '6 k are seen in end view in Fig. 2, supported in their respective boxes, which are fixed in the desired position bythescrews S S, &c. Guides L M N O are introduced between the rolls, as shownin Fig. 3, for the purpose. of directing the barot' metal in the proper path in its passage through the machine.

he train of gears byavh'ieh the rolls are driven is hung in the opposite side of the frame, and the journals of the shafts are supported and adjusted by screws S in the same manner as the journals of the rolls. They are coupled to the shafts of the rolls by means of the sleeves 1 1'', Q, Q, &e., provided with bars I), and with the strips 0 and bands (1 for keeping the sleeves in position when the shafts of the rolls and gears are coupled.- The opening through the sleeves isangular, and -cori;e--

spends in shape and size with the herb and with the inner ends of the journals of the rolls and driving-gears, on whielrthe sleeves are, respectively, placed. This arrangement .is

clearly shown at Q Q, Figs: 1, 4, and 5, the

sleeve Q being placed onthe' inner end of the journal of roll 0 and sleeve Q on the inner end of the journal of shaft 0'. The bar Z) enters both sleeves and connects them, and the strips 0, bound to the bar I) by the straps 01', hold the sleeves apart and on the journals which they respectively receive.

To u-neouple the journals of rolls 0 and C, or any other pair in the series, it is only necessarytoieiuovc the strips 0 aud-bringthe sleeves together, .when they, with the bar b, can be removed from between the ends of the journals to which they had'be'en applied.

The rolls B C D E F G H I J K are arranged relatively to each other in the manner shown in Fig. 3, roll 0 being nearer to.D thanto B, roll E being nearer toF than to 1), and so on through:

out the series, J and K, the final pair, being separated by a distance equal to the final thickness of the rolled metal. The gears on shafts B O D 1*) F G H I J K are so timed as to give increased speed over its predecessor to each successive roll from Bto K so as to produce a combined drawingand compressing action -upon the metal. c

B Fig. 3, marks the bar of metal passin g through the machine. It reeeivesits first re-' duction between rolls 1 and O, the next between C and D, then between 1) and E, E and F, F and G, G and H, H and I, I and J, and finally between J and K, each group of three rolls throughout the series efi'ectiug two -reductions, as clearly shown. v

The guides L M N 0 guide the bar in the proper path through the machine, preventing it from following around either of the rolls which are operating upon it. a

We are aware of the existence of a patent-,-

dated August 12, 1873, No. 141,701, -to E. H. Davies, for a machine for rolling sheet metal, in which is shown a series of pairs of rol'lers,

with gradually-increasing pressure, and hav iug intermediate rollers arranged between the pairs of rollers and resting upon the bottoui'.

ries;

' i We claimrollers of the adjoining" pairs. Such construction we do not claim; but u 1. In a, machine for rolling metal, the combination, in the manner described and shown,

* of a series of rollers arranged relatively to each 0ther,'so that each roller shall be nearer the roller which follows than to the one which precedes it, and so that two reductions of the metal are eflected by three rollers at one operation, all as specified.
