METAL-ROLLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 250,678, dated December 13, 1881.

Application filed March 24, 1881.

To all whom it may concern:

Be it known that I, SAMUEL F. REYNOLDS, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Metal Rolling Machines; and I do hereby declare thatthe 'followingis at'ull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

My invention relates to metal-rolling machines; and it consists in the construction and arrangement of parts, as hereinafter more fully described and claimed.

In the annexed drawings, in which like parts are indicated by like letters inthe several views, Figure 1 is a plan view of the machine. Fig. 2 is an end view. Fig. 3 is a vertical section on the line 00 m, and Figs. 4 and 5 are detail views of dies.

A represents the frame of the machine, which is constructed of suitable material and arranged with braces A A and cross-rods a a, to strengthen and support the operative parts. At one end of the frame A is journaled a driving-shaft, B, that carries at either end the cogged gears or pinions b b. The pinion 1) gears with a cogged wheel, B, which, in turn, engages above with a cogged wheel, 0.

0n the shaft B, that carries the gear-wheel B, is a pinion, I), that engages above with the cogged periphery of a recessed disk, D, on the shaft (1. The adjoining disk D, revolving in the opposite direction on its shaft cl, is driven by the pinion c on the shaft 0, that is operated by the gear-wheel O. The opposite sides of the frame A are connected and strengthened by the cross rods or braces a a, which are screw-threaded at their ends and provided with nuts a a, by which they may be tightened, so as to steady the machine.

E E are the bearings or journalboxes for the operating-shafts.

In machines for rolling wagon-axles I have found it convenient and useful, especially in forming that part of the axle on which the wheel revolves with a shoulder or collar, to provide the machine with two revolving disks carryin g dies, and arranged to be operated by cog- (ModeL) gearings, so as to revolve in opposite directions with equal speed. The dies that are arranged within the recessed disks are so constructed as to cause the iron of which the axle is formed to roll between them sidewise.

The recessed disks D D are provided on one side with ribs 0 e, that radiate from the center and assist in supporting the dies F, which are each provided with a V-shaped notch for the reception of theribs. The die F is provided with a groove, f,for forming the collar or shoulder, and with a depression, f, for breaking the iron down gradually. It is of greater thickness at the center than on the outer side, and that portion of the die that forms the collar gradually increases in thickness from the point 9 to h, the outer side of the die remaining the same from thelatter point to t, whence it gradually decreases to the pointj; but the inside of the die is thicker at k than at I, thus making theiron tnperin g as it passes between the points is and l. The die F (shown in Fig. 5) is a development of the circular die F, and is intended for use in machines provided with sliding plates or beds.

Attached to the cross-pieces A A, and arranged between the revolving disks D D, are beveled guides G G, that hold the iron in position and prevent it from slipping on the. dies. The manner in which these guides are arranged enables the machine to be operated from either Side, the crosspieces A A being perforated at a for the passage of the metal bar.

From the foregoing description the operation and advantages of my machine will be apparent.

When constructing wagon or car axles, carpins, studs for looms, and similar pieces of metal-work requiring a shoulder, the meta bar is passed through the opening a from either end of the machine. The metal is held by the guides Gr G to the action of the dies, which are revolving in opposite directions with equal speed. In this operation the depressed portions of the dies break the iron down gradually, while the groove forms the collar or shoulder, and the thick central parts of the dies finally smooth and finish the work from the shoulder to the end of the bar. I find by experience that when an attempt is made to form the shoulder and break down the whole arm at once the outer side of the metal will draw faster than the center of the bar, thus forming a coldshut or leaving the end of the axlearm hollow; but when the faces of the dies are made with a gradual increase, so as to break the iron down until it is of sufficient length before the thick central portions of the dies pass over it, the work, when finished, will be left solid at the ends. By the time the collar is formed the disks carrying the dies will reach a point during their revolution in opposite directions in which the V-shaped notches in the dies will coincide with the spaces between the guides, so that the finished axle or other article may be readily removed.

Having thus described my invention,what1 claim asnew, and desire to secure by Letters Patent, is

1. In a metal-rolling machine, the diesF,hav-

ing inclined edges, and provided with groovef 20 and depression f, substantially as specified.

2. In a metal-rollin g machine, the dies F F, having on one side a V-shaped notch, and provided with groove f and depression f, in combination with the recessed and toothed disks 25 D D having ribs 0 e, substantially as set forth.

3. In a metal-rolling machine, the'combination of the dies F F, having groovesf and depressions f, recessed disksD D, provided with ribs 0 e, and the beveled guides Gr G, substano tially as shown and described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
