ROLLS FOR ROLLING OVERHANGING SLOT-RAlLS.
SPECIFICATION forming part of Letters Patent No. 387,147, dated July 31, 1888.
Application filed June 12, 1888. Serial No. 276,824. (No model.) i
To all whom it 72mg concern:
Be it known that I, FREDERICK OoLLEY, of Johnstown, in the county of Oambria and State of Pennsylvania, have invented new and useful Rolls for Rolling Overhanging Slot- Rails, which invention is fully set forth and illustrated in the following specification and accompanying drawings.
The object of this invention is to provide a set of rolls for rolling slot-rails for cable railways of the form hereinafter described.
The invention will first be described in detail, and then particularly set forth in the claim.
The accompanying drawings, consisting of two figures, marked, respectively, Figurel and Fig. 2, illustrate two pairs of rolls, the upper roll of each pair being indicated by the letter U, and the lower roll by the letter L. Said rolls contain, collectively, eleven passes, distributed in each pair as follows: Five passes, as shown in Fig. 1, numbered 1 to 5, inclusive; and six passes, as shown in Fig. 2, numbered 6 to 11, inclusive.
The manipulation of the hot metal and the operations of the rolls upon it are performed in the following manner: Pass No.1 is an ordinary slabbing pass, after being rolled through which the billet is entered diagonally and run through pass No. 2. The metal is then entered, after leaving pass No. 2, into and rolled through pass No. 3, excess of work or draft having been brought upon the metal in the former pass at the point A. Turned once, the metal is then entered in and rolled through pass No. 4, in which it is subjected to excess of draft at the point B. Entered next in pass No. 5, without turning, excess of draft is thrown on the metal at the point 0, and an angle is thereby thrown at said point into the head portion of the rail in process of format In passes Nos. 6, 7, and 8 such angular tion.
formation of head portion is still maintained and increased, excessive draft being concentrated on the shoulder portion of the metal (marked D) in said passes. In passes Nos. 9, l0, and 11 the operation consists principally in the truing up and finishing of the rail to the exact form of crosssection desired, the main portion of the draft being concentrated upon the flange portion of the rail (marked E) in said passes. It will be observed that throughout the design of these rolls each pass concentrates an excess of draft upon a specific portion of the mass of metal being rolled, instead of distributing the draft over the whole of such mass generally-that is to say, such treatment is locally concentrated and the rest of the draft distributed with a view to this local concentration.
In the drawings, Fig. 1 shows roughing rolls and Fig. 2 finishing'rolls; but I do not limit myself to the exact number or distribu tion of passes shown, as the number of passes and their distribution into roughing and finishing passes is to a certain ex tent arbitrary, being influenced by the length and diameter of the rolls, a light train of rolls calling for more passes with lighter draft than a heavy rolltrain. It is also evident that the rolls can, if desired, be made three-high instead of tw0- high, as shown.
Having thus fully described the construction and operation of my said rolls, as of my invention I claim- A set of rolls for rolling overhanging slotrails, having passes of the conformations indicated in the accompanying drawings by the numbers 1 to 11, inclusive, substantially as set forth.
