Description
UNITED .STATES PATENT @Prion DAVID EYNON, OF RICHMOND, VIRGINIA, ASSIGNORTO TREDEGAR COMPANY, OF SAME PLACE.
IMPRovED RoUGH|NG -Ro| Specification forming part of Letters Patent No. 102,670, dated May 3, 1870.
I, DAVID EYNoN, (assignor tothe TREDEGAR OOMPANY,) of Richmond, county of Henrico, State of Virginia, have invented Improved Roughing-Rolls, of which the following is a specification Nature md Object of the Intent/ion.
My invention consists of certain improved roughing-rolls, constructed as fully described hereafter, so that old double-headed rails, or
iron of approximate form, or piles, may be so rapidly converted into billets that. the latter can at once, and without reheating, be conf verted by ordinary rolls into merchantable bars.
Description of the Accompanying Drawing.
Figure l is a side view of my improved rolls.
Fig. 2 represents a section of a double-headed rail which may be converted rapidly into a billet by means of the rolls; and Figs. 3 and 4 are sections of piles, each composed of a double-headed rail with other scrap-iron, the said piles being arranged to be acted on by the improved rolls.
General Description.
The highest 11011, D, and lowest ron, E, are precisely alike, and are provided with such grooves and flanges in relation to those of the.
Avertically in one direction by the bottom, d,
of the groove of the intermediate roll and by the portion e of the lower roll, and it will be observed that this portion of the lower roll has slight anges f f, overlapping the said flanges a, and b of the middle roll. The adjacent space B, almost square, is shorter and widerthan the space A, and is bounded4 laterally by the deep flanges h and h' of the lower roll, and vertically by the bottom, fi, of the groove in said roll and by the portion j of the middle roll, the said flan ges h and 11, penetrating a short distance into the grooves of the intermediate roll. The sides of the deep flanges are inclined, the bottoms of the spaces are rounded, and the edges of the illets or shallow flanges f are beveled, as shown in the drawing. The next space, l, is diamondshaped, and is formed by suitable grooves in the lower and intermedi-ate rolls.
Hitherto l have referred to the lower spaces only as being formed by a combination of grooves and iianges. In the lower and -middle rolls, however, the upper spaces are formed by a precisely similar combination.
The groove O and the remainder of the grooves in the rolls are successively reduced in size, so as to draw the billet formed in the grooves A and B into merchantable bars in the ordinary manner.
O Mint.
