- WIRE-DRAWING DRUM.

Specification of Letters Patent.

' l atented Sept. 25, 1906.

Application filed April 14, 1906. Serial No. 811,787.

To all whom it'may concern:

Be it known that 1, JAMES A. HORTON, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Wire-Drawposition sup ing Drums, of which the following is a specification.

This invention relates to the drawing of wire composed of steel or material of similar hardness; and its object is to enable the wire to be subjected to a large number of reductions in a single operation or-continuous process without breaking the wire or impairing its uniform quality.

The invention has particular reference to the construction of a Wire-drawing drum having a wire-forwarding1 seat adapted to prevent the abrasion of t e wire running in contact with the drum, and thus preventing the removal of the coating which is commonly a plied to the wire to prevent direct contact etween the material of the wire and the drawing or reducing dies through which it is assed.

he invention consists in a wire-drawing drum having a wire-forwarding seat of a material which is softer than steel wire and means for clam ing and confining the relatively soft wire-fbrwardingfeat in such manner as to revent it from eing expanded or distorted y the combined action of the wire pressing against it and the lubricating comlied to the wire-forwarding seat, the dies during the drawing opthe wire, an eration.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a sectional view of the wire-drawing drum embodying my invention. Fig. 2 represents a section on line 2 2 of Fig. 1-.

The same numerals of reference indicate the same parts in both figures.

In the drawings, 10 re resents a wiredrawing drum, which ma e one of a series of drums arranged in tan em order, as shown in Letters Patent of the United States No. 742,987, dated November 3, 1903, or the drum may be one of a tier, as shown in Letters Patent No. 784,264, dated March 7, 1905. In either case the drum may be mounted to rotate in a trough or tank adapted to hold a body of liquid lubricating composition in which the drum or drums are immersed, as shown in said Letters Patent No. 784,264, or the lubricating composition may be-applied to the drum, the dies, and the wire by any other suitable means.

"12 represents awire-forwarding seat, the periphery of which constitutes the surface of the drum with which'the wire is in contact. The said seat is made of a material which is, softer than iron or steel wire to the end that the coating of the wire will not be rubbed off nor the wlre abraded by frictioned contact with the drum. The material commonly used for coating all sizes of wire below the largest is bronze, composed of copper and tin, which is laced upon the wire in a suitable bath. 'l he larger sizes of wire are usually coated with a composition composed of lime or some analo ous material.

The wire-forwar in seat 12 of m present invention is compose of a materia which is softer than iron or steel wire. The said material may be of any suitable non-abrasive character. For example, it may be any of the well-known forms of compressed aper or pa er-pulp, rawhide, or other suitab e materia s, including hard wood. The said seat is of annular form and is closely confined or clamped between two metallic sections 13 and 14 of the drum, the said sections being connected in such manner that they exert compressive ressure upon opposite sides of the seat 12, t e sections also projecting outwardlyl from the periphery of the seat 12, so

that t ey prevent the spreadin or widening of the periphery of the seat by the pressure of the wire against it. The sections 13 and 14 are preferably the edge portions of the peri hery of the seat and prevent the corners o the seat from wearing away and forming a crevice into which the wire might enter. Distortion of shouldered at 18 to overlap the seat, due to the softening action of the 5 lubricating liquid and to the pressure of the wire u on the seat, is thus prevented, and a drum avin a durable wire-forwarding seat free from lia ility to abrade the wire and remove the coating therefrom is rovided.

A wireforwarding seat of t is character permits the wire to be subjected to alarge number of reductions in a single operation or continuous process without impairment of the wire or its coating and therefore without liability of breaking the wire or impairing its uniform quality.

If the seat 12 is made of Wood, a number of wooden sections 15 may be employed, these being arranged with the grain of the wood extending in a radial direction from the center of the drum to its periphery and tightly clamped between the metallic sections 13 and 14. Any suitable hard wood, such as rockmaple, may be emplo ed The wood may be saturated or treate with oil or paraflin to prevent the absorption of liquid.

I claim 1. A wire-drawing drum having a wireseat com osed of material softer than the wire, an means for confining said seat to prevent spreading or distortion of the same.

2. A wire-drawing drum having a wireseat com osed of a material softer than the wire,v an metallic drum-sections between which the said seat is clamped, the sections projecting outwardly from the periphery of the seat.

3. A wire-drawing drum havinga wireseat com osed of a material softer than the wire, an metallic drum-sections between which the said seat is clamped, the sections projecting outwardly from the eriphery of the seat, and shouldered to over ap the edge portions of said periphe In testimony whereo i I have aflixed my signature in presence of two witnesses.
