Specification forming part of Letters Patent No. 196,371, dated October 23, 1877; application filed August 25, 1877.

To all whom "it may concern:

Improvement in Machinery for Rolling Wire Rods, which improvement is fully set forth in the following specification and accompanying drawings, in which latter Figure 1 is a perspective view of a set of rollers provided with a repeater or rod-conductor constructed in accordance with my invention. Fig. 2 is a transverse section of the said repeater or conductor in the line :0 w of Fig. 1. Fig. 3 1s a transverse section of the same in either the line y 3 or z z of Fig. 1. Fig.

4 is avertical longitudinal section of the same I in the line as w of Fig. 1. Fig. 5 is an end view of the delivery-opening in the delivering end of the repeater, and Fig. 6 is a similar view of the delivering end of a repeater adapted for a differently-shaped rod.

The nature of my invention consists, first, in

an open conductor, terminating in tube form at its delivering end, whereby the billet is guided in the proper direction from the open conductor to the receiving-rollers, and is al-' lowed to pass outside and beyond the central part of the conductor, as occasion requires; second, in a mode of connecting the said conductor to its delivering tube-shaped end by a pivot, whereby the contrivance is rendered adjustable to difierently-located roller-grooves.

My invention is especially adapted to the manufacture of rods of small diameter--such as wire rods, chain-rods, and small rounds, the production of which in great lengths is an advantage to the manufacturer, but is usually attended with a certain number of difficulties which have not heretofore been wholly overcome.

A good rod cannot be made of an overheated billet, nor should it be delivered too cold by the finishing-rollers. These objections have heretofore been proposed to be avoided by revolving the rollers with a high speed, and by introducing the forward end of the billet immediately after its appearance from the first pair of rollers to the next pair. To accomplish this properly the most skilled and active men are required to be placed in charge of the work; but this entails an expense which the manufacturer cannot well afford, for various Be it known that I, WILLIAM W. MCCALLIP, of Columbus, in the county of Franklin and, State of Ohio, have invented a new and useful reasons. And for overcoming the latter difficulty different mechanical contrivances have been invented; but these have not come into general use, on account of the great inconvenience and co st attending their construction, their adoption involving a change of the gearing, housing, and diameters of the rollers, as well as other alterations.

\Vith my improved repeater I am en. bled to dispense with the services of one skilled hand, and its cost of construction is so small that it can be adopted in even the smallest espeater is bent in a curve toward the rollers B,

and in transverse section is substantially of the form represented in the drawing, it being of greater height at the outer edge than on the inner, in order to prevent the billet from slipping over at the commencement of the rolling operation, and before the end of the rod or billet has entered between the rollers B.

It has been found that at the point indicated by line a: m a sectional shape, such asshown in Fig. 2, is the most advantageous for guiding, and that at the center of the conductor 0, or near the line y y, and at the line z 2, its shape may be slightly varied in the manner indicated by the section in Fig. 3, in order to facilitate the motion of the rod or billet out of and beyond the conductor, after it has entered the rollers B, which are fed with a smaller amount of metal in a given time than the rollers A are discharging.

The conductor 0, near the rollers B, extends into a tube, D, with which it is connected by means of a loose rivet or bolt, 0, which serves as a pivot for the connected parts to swing on laterally, and so that the said conductor may be adjusted to come in range with or opposite other grooves of the rollers, as occasiondemands. The mouth (I of the tube D is trumpetshaped or flared, so as to properly guide the end of the billet into the tube. The end of the tube D is inserted between the stationary guide 1 Jr of the rollers 13, and the. conductor 6 is sup ported by legschor otherwise. The tube '1),

V at its forwardend, is contracted, as indicated in Fig. 4, at d," and I terminates with an. opening, 6 or. 0?, which is of a diameter and shape I corresponding with the billet or unfinishedrod.

The loillet has to undergo a change: oil shape a with. every new set of rollers it passes through, (the mosticommon of which changes are from.

a The production of a finished rod from .a hi 0 letrequiresaseries of rollcrs,which,"in prae.

much time saved in the manufacture of the rod, and the billet retains its heat and welding condition up to the last moment of opera tion. Moreover, it requires only one common hand at each side of the whole series of rollers to watch the operation of the conductors, while without-the conductors two good, skillful hands have to attend to each side.

Operation: The billet is passed between the rollers A and discharged over the guide a upon: the conductor 0, audin its passage it fol lewsthe curvature :of the repeater all around, x

as the inner dotted lines indicate in Fig. 1, I

and entersthe tube ZD, andis guided thereby into theproper groo esibetweentherollersB. 7 After the rollers B commence to roll the billet, it is fed thereto "faster than; the: speed i of said rollers B, on account oi'f the reduction. of size 7 the metal undergoes, and, in consequence thereof} the length 'of'thiebillet betweenthe rollers A and B is constantly increasing; This 7 causes the billet to rise over the outer rim of the conductor :andformanniiorm loop outside a a of a, as the outer dottedlines'in'Figrllindi 1' i w '7 5 J :cate, which increases until the billet leaves the rollers A, when the rollers 13 can'draw in r i the said outside loop without difficulty, and:
