EDWARD L. LAMB, OF CHICAGO, ILLINOIS.
CASTING ROLLS.
SPECIFICATION forming part of Letters Patent No. 225,479, dated March 16, 1880.
Application filed June 16, 1879.
To all whom it may concern:
Be it known that I, EDWARD L. LAMB, of the city of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in the Casting of Rolls for Rolling Metals; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use thesame, reference bein g had to the accompanying drawing, and to letters of reference marked thereon, which form a part of this specification, in which the figure is a longitudinal central section of a mold and roll therein, the core of the roll being shown in elevation.
The nature of my invention consists in forming a sand mold for the body and necks of the roll, supporting Within such mold by a nonchilling support a core adapted to chill the roll-body only,and pouring around such core the material to constitute the body and necks of the roll, as hereinafter described.
In the drawing, A represents the body, and a a the necks, of the roll; B, the chill-core; O, the non-chilling support of the core; D, the mold-box, and E the sand mold.
In carrying out my invention I construct a D, of any size desired, and arrange therein a sand mold, E, of the form required, as shown in the drawing. In the center of this mold, by means of any suitable non-chilling support, c,a core, B, adapted to internally chill the body of the roll only, is supported, as shown, and then around it is poured the material to constitute the bodyAand necks a a, as also shown in the drawing.
By this method I am able to construct a roll with its body only chilled internally about a chill-core, while its outer surface and necks remain unchilled.
I am aware that rolls for reducing metals have been made by pouring metal about a solid core, but with the core so constructed and arranged as to form either the necks of the roll or to extend entirely through the portions forming the necks.
Having thus described my I claim is- The method of casting an internally-chilled roll, as hereinbefore described, which consists in forming a sand mold for the body and necks of the roll, and supporting within such mold by a non-chilling support a core adapted to chill the roll-body only, and pouring around such core the material to constitute the body and necks, as shown and set forth.
In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
invention, what .EDWARD L. LAMB.
