Tonll whom it'ma/y concern.` y Beit known that I, JAMES iL'HoRigoN,` of county of Providencevl and new and useful Im rovements in Wire-Drawing Machines, of w 'ch the following isI a speci- This 4invention relates to machines for4 drawing iron or steel wire by a continuons process, the wire passing through several dies in a series and around wire through the dies.

A type of continuous-process machineto; which my. invention relates is shown in Let-` ters Patent of the United States No.- 742,987,- dated N ovemb'erB, 1903. In the said machine each of the drums has a wire-forwarding device, preferably-composed of a series of shoes loosely encirclin the drum and having an automatically regu ating or compensating lconnection therewith, whereby slippage between the wire and the wire-engaging surface of the drum is -substantially avoided, such slipping being objectionable, because, first, of the inequalities caused thereby in the distribution of strains on the wire, tendin to break the latter, and, secondly, because o the slippage on the protective coating of the wire, which coating is essential to prevent contact between the metalv of the wire and the die. y f It is important that the contacting surfaces of the drum and the wire-forwarding device thereon be lubricated to prevent the forwarding device from being locked to the drum by excessive friction, and it is further im ortant that the lubrication be uniform and continuous and of such naturev that the forwarding device may at all times be adapted to slip circumferentlally on the drum4 and also be frictionally driven by the drum at the speed required by the callor tension of the.

In the `above-named Letters Patent I have contacting surfaces uniformly and continuously lubricated by immersion in of lubricating liquid in which the wire e dies are also immersed, the' machine being adapted for what is known as weta The present invention has for its object, rst, to provide suitable means for the continssaciamin of netten Patent.
