DAVID REEVES, 0E PEcE'NIXvILLE, AssIGNoa To PPIcENIX'IEoN COMPANY,
' or PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN'THE CONSTRUCTION OF- ROILS TOR ROLLING METAL'.
slimme-anon for'ming pm ofiileaersratem N O. 39,869, dagen June 9, 1863.
To ,alla/tem it may' concern:
Een known that I, DAVID REEVES, of Ph.
nixville, in the county of Chester and State'of Pennsylvania, have invented a new and'Improved Manner -of Making a Compound Roll of Wrought andGast Iron; and I do hereby declare the following to'be a full, clear,`and
exact description ofthe manner of making the'same, reference beingahad to lthe accompanying draiyings, making a part of this speciticatiomin ivhich` Figure l represents an end View of a fagot 'or pile of wrought-iron, which, Awhen welded, becomes the-central portion of the roll. Fig.
Vention 'is -to overcome this diiiiculty, and I.,
have effected it by adopting the mode h 'ereinl after described of constructing such. rolls.
I first take a -ronnd shaft, A, of wroughtiron, of suitable diameter-say six or seven' inches--and-surround it byl other beveled shaped pieces of Wrought-iron, Bof a segmental form, as shown in Figs. l aud--2. These pie'c'es are held in place by the bands() U C, as shown i-nFig. 2. The pile'thus formed is charged into a heating-furnaceand brought up vto a Welding-heat. It'isthen Withdrawn from the furnace and passed between rollers, by Which'process the pieces arewelded into one solid mass, the pile being reduced some; what in diameter, and correspondingly increased in length, Tvhile the grain of the ironlie's inthe direction which 4gives vthegreatest power to resist torsion or transverse strains.
After' welding and rolling', I place the shaft in a lathe, f orjtbe purpose of reducing its surface toa true circle, and afterward make sev, eral circular and longitudinal channels a b on the perimeter of the'piece, as shown in Fig. 8.-
, When the shaft or centerof the roll is thu-s prepared, In make a mold in a flask of'thesize and form required for the roller, as I would 4Were I about to make a solid cast-irou'roller. yThe flask is'theu placed in an upright posi-v tion, having one end openlsuiicient to admit the wrought-iron shaft. Havingfthusfpr- .pared theA flask, the Wrought-iron shaft 'is placed on bearings and a coal or Nood fire is built around it, and it is heated up to a bright cherry-red. At this stage of the process the 4metal intended for casting around the shaft is Ain a molten state.' YWhen the shaft is hot en0ugh,it. is hoistedfrom the iire,and is let dotviiinto the center of the mold and secured in plape, and thus preparedthe molten metal D is poured intothe-mold around the shaft uutilthe mold is filled. The molten metal enters intoand llsthe circular and longitudinal channels. of the Wrought-iron shaft, as
also the vacant space around it. When cooled,`
the roller is taken .out of the ask, and the cast-iron envelope is found to be thoroughly fastened vupon thewroug'htfiron center. The roller is then ready for being. turned up "in a lathe, and for receiving its grooves in the usual manner practiced in rollturning. The cast-iron may be sufficiently thick to'permit the grooves being made. in it without-.reaching to the depth of the Wrought-iron, while the Wrought-iron` shaft may be sutieiently thick to make the full diameter required for the journals where its superior .strength over cast-iron prevents thegreat strain upon the rollers in the process of rolling from breaking at their necks, as is frequently the ease with rollers made entirely of east-iron. A- compound roller of Wrought andfcast iron is thus perfectly made; the wroughtirn, having-been heated to the limit of its expansion, contracts with the cast metal, thus relieving the enor mous strainA that the vcast lmetal would beother-wise subjected to.
If desirable for 'any spe l'al purpose, the
l' wrought-iron center may be hollow, as a hollosw instead of a solidceuter piece,"A, may b'c u cd.
Having'thus fully described my method-of making rolls for rolling irn and other metals, I would state that I' am aware that a fagot or pile of vwrought-iron-., such 'as I propose for the center of the roll has been made, and this I do notlclaim; but WVhat I de claim as of my invention, and desire tosecure by Letters Patent, is A compound roller made of Wroughtand cast iron, in the manner and for the purpose substantially as herein described. y DAVID REEVES.
