UNITED i STATES PATILMIQM HENRY A. WILLIAMS, `OF TAUNTON, MASSACHUSETTS.
ROLLS Foa ROLLING Roos, sbo.
SPECIFICATION forming part of Letters Patent No. 367,8/779, dated August 9, 1887.
i Application filed October 4, 1886. Serial No. 215,232. (No model.)
T0 all whom, it may concern:
Be it known that I, HENRY A. VILLIAMS, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Machines for Reducing Metal Rods, of which the following is a specification, reference being had to the accompanying drawings.
Figure 1 is a plan of part of a machine provided with reducing and finishing rolls embodying my invention.Y Fig. 2 shows a portion of a pair of finishing-rolls embodying my invention, with part of a spindle between them. Fig. 3 shows a portion of a pair of reduci n g-rol ls embodying my invention; and Fig.
4L shows ajpair of rolls of uniform diameter embodying my invention, with a portion of a spindle between them.
Machines for reducing metal rods by pressure between a pair of rolls, with the axis of the rod substantially parallel with the axis of the rolls, have long been know/n; and my invention is an improvement applicable to machines of this class, including machines in which the working-surfaces are on plates instead of rolls, for, as will be clear, the working-surface may be either the periphery of a roll or the face of a metal plate. Inasmuch as I esteem that form of machine in which rolls are used as preferable, I have shown my invention as applied to that form; but, as will be clear, it is applicable to either form.
du reducing-machines I have found that the amount of surface-contact between the surfaces of the reducing rolls or plates and the surface of the rod to be reduced is so great that it greatly increasesthe difficulty of reducing the rod to its desired shapedas, for instance, in reducing a rod of uniform diameter' to a taper, (as in making spindles, hacklepins, or the like,) or a rod of uniform diameter to varying diameters, (as in making car-coupling pins,) or in the manufacture of steel bullets from a rod of uniform diameter. I have discovered that this difficulty is obviated by cutting slanting grooves in the .reducing-surfaces, and so arranging these grooves that the working-surfaces between them shall always be opposed. Slanting grooves thus arranged leave the working-surfaces unaltered, so far as concerns their operation in reducing the rod to its desired shape, (whether tapered, conical, spherical, or cylindricaL) but greatly affeet-the operation of these surfaces, by causing them to act in a novel and peculiar manner, for each working-surface is practically divided into anumber of narrow strips, each doing its part of the work. Moreover, the slanting grooves allow free space for the motion of the particles of metal in the rod which is reduced.
In'order to insure a smooth surface on the finished article, it is necessary that the width of the spaces between the grooves shall be slightly greater than the width of the grooves, as this causes each strip of the working-surface to operate not only on its own portion of the rod, but also to operate at its edges on that portion 'of the bed operated upon by the neighboring strips of the working-surfaces. All this will be clear to all skilled in the art from the drawings, which illustrate my invention as applied to the rolls of a reducing-machine which forms the subject-matter of my application for patent now pending, Serial No. 194,455, tiled March 8, 1886.
In Figs. l, 2, and 3 the rolls are designed for a spindle, and the other rolls for reducing a rod to a taper, or when aV rod is inserted be tween them and they are brought slightly nearer together and set they simply reduce the diameter and true a cylindrical rod. These rolls and the other parts shown are the same as in my pending application, (and are there fore not described here,) with the exception that the'working-surfaces of the rolls are subdivided into a number of strips, d a a2, Snc., by a number of slanting grooves, b b' b, V&c., the strips and the grooves extending entirely around the rolls. Each of these surfaces a da, as will now be clear, does its own work on the rod to be reduced, but the total work done by all is precisely the same as if the original working-surface had not been subdivided by the grooves; but the work is done far more read- -ilyand with less resistance from themetal of the rod to be reduced, because the grooves allow the metal to flow freely, which flow would be obstructed were the rollingvsurface not subdivided by the slanting grooves.
The depth of the grooves is not material, as
Vhat I claim as my invention is- In a rod-reducing machine, two workingsurfaces, each of which is wholl y made up of a 15 series of slanting lands, a a' ai, &c., separated by grooves b b b2, the., substantially as and for the purpose set forth.
