S. JOHNSTON." METAL ROLLING MACHINE. No. 455,336. Patented July' 7,1891.
Z INVENTOR:

' tween these NTTED STATES PATENT OFFICE.
SAMUEL JOHNSTON, OF DENVER, COLORADO.
METAL-ROLLING MACHINE.
SPECIFICATION forming part of Letters Patent No. 455,336, dated July 7, 1891.
Application filed July 14. 1890- .lo all whom it may concern.-
Be it known that I, SAMUEL JOHNSTON, a citizen of the United States, residing at Denver, county of Arapahoe, and State of Colorado, have invented a new and useful Improvement in Metal-Rolling Machinesfof which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
Figure 1 represents a front elevation of my improved arrangement of rolls Fig. 2, a longitudinal section of the same; Fig. 3, an end View of rolls and shell on line 00 y, Fig. 2; 4, an enlarged sectional view of the drawing and finishing rolls.
My improvement has for its object the reduction and finishing of rods, shafting, tubes, &c.,of metal, of iron,steel,orsteely-iron; and it consists in the employment of a series of rolls inclosed in a strong shell which surrounds the rolls. These rolls are arranged so that the rod or tube shall be passed between the rolls in aline parallel to their axes. The rolls with the inclosing shell are made to revolve around the rod. The rods are progressively fed berolls by means of a pair of feeding-rollers opposite each endof the shell.
These feeding-rolls at the same time that they feed the rod longitudinally forward between the shell-rolls prevent the rod from revolving and hold it steadily against all tendency to turn.
AA AA AA AA AA represent the rollers, of about one foot to three feet in length and of about one-fourth totwelve inches in diameter, depending on the diameter of the rod to be treated. These rollers AA AA AA AA AA are made of hardened steel or chilled iron and are frust-ums of cones very slightly tapering and rounded at the receiving ends A A A A A. A series of five of these rolls AA AA AA AA AA are arranged within a strong iron shell BB, made of cast-iron, of a cylindrical exterior BB, and the interior is the shape of the frustum of a cone. This interior has a chilled-iron surface. When the rolls AA AA AA AA AA are placed within the shell and surround the rod 0, the'slightlytapering rolls AA AA AA AA AA correspond with the reverse taper of the shell, so that the interior space occupied by the rod Fig.
Serial No. 358,727. (No model.)
C will present a space adapted toreceive a cylindrical bar, the circle thereof being tangent to the rolls AA AA AA AA AA, and
the diameter of the space between the rolls and the cylinder being uniform throughout, as shown in Figs. 2 and 4.
The rolls AA AA AA AA AA are not journaled, but are placed loosely in the shell B. The pressure on each of the rolls AA AA AA AA AA is brought bythe inner surface of the shell in contact with the outer surface of each of the rolls AA AA AA AA AA throughout their length.
There are end brackets or projections at E E, which extend from the shell internally,
and against them the ends of the rolls AA,
approximate the rolls, andthus make up for the wear. The shell revolves in boxes or end bearings. (Shown at H H in Figs. 1, 2,3,and 4.) The shell is madewith exterior corrugations 9 g g or grooves on its outer circumference and is driven by rope belting 70 k. Opposite each end of this set-off are placed a pair of ordinarygrooved rolls K K, which feed the'rod into the center space between the rolls AA AA, &c., and force it along the central space between those rolls, so that the rod gradually progresses while it is compressed, drawn, and finished by the rolls AA AA, &c. At the opposite end another pair of rolls J J receive the rod as it emerges from the series of rolls AA AA, &c. The rolls K I K and J J are geared and driven in the usual manner.
- The operation'is as follows: The rod or tube, either heated or cold, is passed between the rolls K K and forced by these rolls into and through the central space between the rolls AA AA, &c. As the rod is'forced through this space, the rolls AA AA, 620., revolving freely in contact with the rod, produce the drawing, straightening, and finishing process upon the rod. The rod as it emerges passes between the rolls J J. The
rolls K K and J J so-operate infeeding the rod through and prevent it from turning,'
while the constant passage of the rolls AA AA, &c., in the revolving shell around the rod finishes it and draws it in a more perfect manner than has been heretofore eflt'ected.
For drawing and reducing Wire the feeding-rolls K K should be dispensed with and the rods drawn between the rolls AA AA, &e., by the rolls J J.
Having now fully described my invention,
What I claim-as new, and desire to protect by Letters Patent, is
1. The combination of the longitudinal drawing and finishing rolls AA AA AA AA AA, the revolving shell BB, and the feeding or holding rolls K K. i
2. The combination of the longitudinal drawing and finishing rolls AA AA AA AA AA with the feeding-rolls J J v SAML. JOHNSTON. 'Witnesses:
