IMPROVEMENT IN MACHINESFOR ROLLING BLOOMS.
Specification forming part of Letters Patent No. 139,358, dated May 27, 1873; application filed r June 29, 1872.
To all whom t may concern:
Be it known that I, GEORGE W. BILLINGs, of Chicago, Cook county, Illinois, have invented a Machine for Welding Piles for Railroad Rails, Beams, Bars, and other things of Iron, of which the following is a specification:
In the drawings, Figure l represents a side elevation of the rollers, their housings, boxes, and adj usting-screws; Fig. 2, a vertical transverse section of the same taken on the line :v
y of Fig. l.
a a represent the housings; b b, the journal-boxes 5 c c, the screws for holding the rollers together. These several parts are of ordinary construction, and may have the strength and capacity for piles of any size, capable of being heated and handled in a furnace. d, e, and fare the welding-rollers which are intened to be geared and driven in the ordinary manner.
The rollers are from twenty to twenty-four inches in diameter, and about five feet in length between the housings, and divided by several transverse collars or bosses, g, into several spaces, as follows, viz: The middle roller e is divided into four spaces, all of which are cogged, as shown; the upper roller d and lower roller f are similarly divided, but only two the spaces of these rollers d and f are provided with cogs, the other two spaces of each being left blank. The middle roller e is of a varying diameter, the diameter being different in each of its four cogged spaces. The cogged spaces of the upper and lower rollers ol and f, respectively, are each the same in diameter as the opposite or corresponding spaces, respectively, of the middle roller e.
This construction and arrangement of the Spaces are necessary in order that when a pile is passed through any one of the spaces, the rollers acting on it above and below shall tend to move it uniformly, or with the same rate of motion.
I give the gears a pitch of about two inches, measuring from center to center of the pitchline of the meshing cogs. The spaces between the cogs are about eight (8) per cent. wider than the faces of the cogs respectively. The cogs have a depth of about three-quarters of an inch.
The pile having passed through the corre-` sponding cogged spaces of rollers e and f is returned between the corresponding cogged spaces of the rollers d and e, and in this way there is secured an almost continuous pressure and a thorough Welding or amalgamation of the metal before it has time to cool.
The action of the cogs in the roller spaces is such that the parts of the pile are pressed i together without much, if any, draft ofthe pile, it being a very little longer after the weldin g operation than it was before. A
Four passes through the rollers are suicient to thoroughly Weld any ordinary pile of iron, and when so welded the pile is returned to the furnace for a second heating, and then by a train of the common draft-rollers is drawn into the shape desired.
The pile may be passed two or three times through the cogged spaces of the rollers, as described, and then at once, without reheating, may be passed through the draft-rollers for final shaping.
I claim- The combination of the three welding-rollers d, e, and f, each of which is divided by bosses g into spaces whereof the cogged spaces of the upper roller d are the same in diameter as the respective corresponding or opposite spaces of the middle roller e, and the cogged spaces of the lowerroller f are the same in diameter as the respective correspond! ing cogged spaces of the middle roller e, so that the pile can be passed backand lforth between the rollers and thoroughly welded Without material elongation of the pile, subr stantially as set forth.
GEORGE W. BILLINGS.
