EDYARD SIMPSON, OF JOHNSTOWN, PENNSYLVANIA, ASSIGNOR TO THE JOHNSON STEEL STREET RAIL COMPANY, OF KENTUCKY.
MILL FOR ROLLING SIDE-FLANGED GROOVED RAILS.
SPECIFICATION forming part of Letters Patent No. 394,022, dated December 4, 1888.
Application filed February 16, 1888. Serial No. 264,137. (No model.)
The invention will first be described in detail, and then particularly set forth in the claim.
In the acctunpanying drawing the figure shows in front elevation a. pair of rolls, the letter A imlicating the top roll and 13 the bottom roll. Said rolls are provided with six passes, numbered accordingly 1 2 3 l 5 U.
The bloom having been first reduced to any shape of? cross-section suitable to enter pass No. 1, is then entered therein, and, having been rolled through the same, is next successively rolled in each of the following passes, being finished in the last or final pass, N0. 6.
The rolls may be mounted in any suitable housings of well-known construction.
It will be noted that the projection which forms the groove in the finished rail, is of smaller proportions than the guard shown in the finished section shown in my application Serial No. 264,136, herewith filed, and that,
moreover, it is level, or nearly so, with the head 0 of said finished section, necessitating a modification of passes, as shown, between the two applications. For it will be seen that in passes Nos. 1. and 2 there is no ofi'fset provided for the initial formation of the guard, both groove and guard being formed entirely in passes Nos. -.t and 13. Thus, whereas four passes are required to form the groove and super-elevated guard in said application Serial No. 261,136, but two passes only form the groove in this application.
I do not limit myself to the exact number or disposition of passes shown, as the number of passes and their distribution into roughing or reducing and finishing passes is to a certain extent 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 roll-train. It is also evident that the rolls can, if desired, be made three-high instead of two-high, as shown.
Having thus fully described my said improveinent, as of my invention I claim- A set of rolls for rolling side-flanged grooved rails, provided with passes, substantially as hereinbet'ore described, having the conformations indicated in the accompanying drawing by the nun'lbers from 1 to 13, inclusive, substantially as and for the purposes set forth.
