VIITN SSEs UNITED STATES PATENT OFFICE- PETER M. WEBER, OF MUNHALL, PENNSYLVANIA, ASSIGNOR To THE CAR- NEGIE sTEEL co PANY, LIMITED, or PITTsB'uRe, PENNSYLVANIA.
ROLLS.
SPECIFICATION forming part of Letters Patent No. 606,608, dated June 28, 1898.
Application filed May 22,1897. $erial No. 637,690. (No model.) 7
To all whom it may concern:
Be it known that I, PETER M. WEBER, of Munhall, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Rolls, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, in which the figure is a diagrammatic view, showing rolls provided with my improved set of passes for rolling flats from blooms or billets.
My invention relates to the rolling of fiat sheets or bars, such as are usedfor tin plates, pipes, strips, 850., and is designed to provide an improved set of passes for rolls employed in forming such material whereby the re duction can be easily and quickly elfected without injuring the metal by changes in the direction of its flow during reduction.
In the drawing, A, B, O, D, E, and F represent the successive passes within which the metal is rolled. At the first pass the rolls are provided with annular projections arranged to form a single upper and lower longitudinal groovein the metal. Passes B, O, and D are also arranged to spread the metal laterally and lessen its thickness, the grooves being made flatter and shallower in each of these passes. In pass E the metal is narrowed slightly and lessened in thickness, the edges being squared up and the piece being fiattened. In the final pass F the metal is lessened in thickness and spread laterally.
The advantages of my invention result from the fact that the first pass forms an upper and lower longitudinal groove in the metal, while the next successive passes are shallower and wider, the grooves being retained, but being spread and made shallower, The
metal, therefore, is caused to How in the same general direction in each of these passes, thus preventing injury to the metal as each pass more nearly approximates the flat bar finally obtained. Any defects in the edge portions of the metal are squared up in the fifth pass,which flattens the metal and squares up theedges. The number of passes may be varied, as may'also the shape and size of the grooves or longitudinal depressions, and many other variations will suggest themselves to those skilled in the art without departing from my invention, since What I claim is 1. In apparatus for rolling fiat sheets or bars, rolls having at the first pass registeringprojections arranged to form a single upper and lower registering groove in the metal and succeeding passes having symmetrical flatter and wider projections arranged to spread the metal symmetrically in a lateral direction and fiatten'the grooves to substantially the same amount upon each side.
2. In apparatus for rolling fiat sheets or bars, rolls having at the first pass annular projections arranged to form a single upper and a single lower groove in the metal, said grooves registering with each other, intermediate passes provided with registering wider and shallower projections arranged to spread the metal symmetrically on each side, and a pass arranged to narrow the metal slightly and flatten the same.
In testimony whereof I have hereunto set my hand.
