VILLIAM A. SVEET, OF SYBAOUSE, NEW YORK.

IMPROVED ROLL FOR SPLITTING RAILROAD-RAILS.

Specification forming part of Letters Patent No. 95,284, dated September 28, 1869.

To @ZZ whom it may concerm Be it known that l, WILLIAM A. SWEET, of the city of Syracuse, county of Onondaga, and State of New York, have invented a new and Improved Form of Bolls for Splitting Bailroad-Bails; and I do hereby declare the following to be a sufficiently clear and exact description of my invention, reference being made to the accompanying drawings and letters thereon, that any one skilled in such matters may make and use the same.

Figure l represents a side elevation of m invention. Fig. 2 is a sectional view of one of the stands, showing the journals of the rolls in elevation.

Like letters refer to like parts in both views.

The chief object of this invention is to prepare the scrap of railroad-rails and beams, where flanges are projected from a web, for conversion into other useful products or artcles of manufacture; and it consists in so constructing a pair of rolls as that the webs or flanges of rails or beams may by one operation be severed or split apart from their corresponding members, and at once, if desired, passed through the other operations to convert the several parts into useful products, without the necessity of reheating them.

Manufacturers have heretofore considered all the portions of rails and beams that accumulate inthe rolling-mill by whatever causesuch as the ingots being either too small or too large to produce the exact length of rail or beam-as simply so much scrap, not capable of being either rolled or hammered into any useful form on account of the flanges being so wide and thin that seams or cold sheets77 are always formed during the operation; bu-t I have learned from a great number of experiments that by a cheap process of splitting or severing these several partsas the base, web, and head of a rail-the head may be profitably converted kinto crowbars, wheel-tires, sleigh-soles, 85e., and the other portions' (if the rail is of steel) may be easily converted into stock for seat-springs and similar articles, completely avoiding the necessity of repiling, fagoting, or rerolling in order to make it suitable for conversion into new and useful articles of manufacture. It may seem at first sight, at least to any one not skilled in such operations, that little, if any, difficulty need arise in making a pair of rolls perform the operation of splitting such material but experiment has proven that the cutting-edges of the rolls must be held very closely and firmly together-so closely, in fact, that if permitted to run empty the edges would soon be destroyed 5 but this difficulty I have completely overcome by mounting the rolls in stands so constructed that the moment the binding-screws are relieved the bottom roll drops from contact with the upper one, and by forming the rolls so that guards to the cutting-edges shall always protect them from any injurious contact.

A A are the stands or frame for supporting the rolls B and B. These stands are of any suitable material-such as cast-iron-and are securely mounted upon a base, A', by bolts extending down through timbers and masonry of sufficient solidity to furnish a firm though slightly elastic foundation. rIhe rolls B and B may be formed of the same materials as those used for rolling iron, and the edges or critters for splitting, as shown at i in Fig. 1,

are made of as great a diameter as any other portion of the rolls; but at m and n guards to the cutting-edges are provided by leaving a considerable surface of metal, of equal rdiameter to the cutting-edges, and said guards receive the pressure of the binding-screws, and serve as a gage to the operators for applying pressure upon the rolls. The inner edges or corners of these guards also serve as guides to the material to be split, and between these and the cutting-edges are the grooves through which the rails or beams are to pass, as at l, 2, and 3, the base of a rail passing through at l, the web at 2, and the head at 3; or, if a beam, the grooves and cutting-edges are made to correspond with its dimensions, but in a` similar manner. The bottom roll is supported in working position upon the movable boxes or brasses e e, which are raised or lowered by the set-screws o o, said set-screws being geared to work together by the spurwheels C C, which are operated 4by a pinion upon the hand-wheel shaft D. rlhe upper roll is supported in bearings in the stands, as shown at A, Fig. 2, so that how far soever the lower roll may be dropped or lowered the upper one will not be affected thereby in any manner. Its brasses tt are forced down upon it by suitable binding-screws, as in the ordinary style of rolling-mills, but when once properly set is left to Work in that position, as all adjustment between the two rolls is effeeted by operating the lower screws, as :Llready described.

strueted and arranged as described, brasses e e, set-serews o o, spur-Wheels G C, pinion, and hand-Wheel D, substantially as described, and for the purposes set forth.

Having thus briey described my invention, XVM. A. SWEET. what I claim, and desire to secure by Letters Vitnesses: Patent, is- Gno. W. Hlimvoon,

The combination of the rolls B and B', con- ITJEUBEN MURRAY.
