CONTINUOUS ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 328,591y dated October 20, 1885. Application filed April 13, 1885. Serial No. 162,019. r(No model.)

To all whom t may concern.-

Be it known that I, 'EDWIN S. LENGX, a citizen of the United States, residing at Vorcester, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Rolling- Mills for Bolling IVire Rods 5 and I declare the following to be a description of my said invention sufficiently full, clear, and exact to enable others skilled in the art to which it apperiains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

The object of my present invention is to provide a rolling-mill for making wire rods that will produce small-sized rods at a single heat, and in which the rod at the latter portion of the mill will be carried and reduced surely and rapidly and without liability of forcing the metal in a manner that will produce fins upon the rods. This object I attain by an apparatus in which the leading portion of the mill is composed of series of rolls operating in pairs, for breaking down the bar and extending its reduction to a stage where the rod is of a size of about No. 5 wire gage, while the latter portion of the mill,for further reducing the extenuated rod,is composed of sets of rolls arranged to operate as triplets, or three or more rolls in each set. The particular subject -matter claimed is hereinafter definitely specified.

In the drawings I have represented different arrangements of wire-rod rolling-mills, illustrating the manner in which my invention may be applied to use, and which modifications I include as within the scope of my said invention.

Figure l is a plan view of so much of a wire-rod rolling-mill as will illustrate the nature of my invention. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a diagram illustratinga modification in the arrangement of the latter portion of the mill. Fig. 4 is a diagram showing another modification,in which anintermediate double-inclined over-feed table is employed. Fig. 5 is a view illustrating the arrangement of the triple rolls.

In my improvement the first part of the mill consists of a series of rolls, c to c", arranged in pairs for operating in the order commonly known as a continuous rollingmill. In this train ten pairs of rolls (more or less) may be employed, which are grooved for effecting the reduction of the bar or billet from a diameter of about one and one-half inch to a partially-formed wire rod of about No. 5 wire gage, more or less. At this stage of the reduction I change the construction and arrangement of the mill and employ for the further reduction and finishing of the rod series or sets of rolls, which are arranged in triplets, or with three or more rolls operating upon the rod at the same position. Of these triplet rolls I preferably use four sets, although a greater or less number of such sets may be used, if desired, in connection with the lead-` ing train of rolls arranged in pairs. The sets of triplet rolls may be combined with the leading continuous train of rolls c to c, either as shown in Figs. 1 and 2, to operate as a continuous mill, and directly following said pairs of rolls, or the mill may be arranged as shown in Fig. 3, the sets B B B2 B3 of triplet rolls being arranged in the order known as the Belgian mill, or with the sets disposed in lateral right and left arrangement, as indicated, so that rods as they issue from the leading continuous train Amay be alternately led through the triplet sets, one to the right and the next to the left; or, again, the mill may be constructed as indicated in diagram Fig. d-viz., with a primary train of rolls, A, arranged in pairs in continuous7 order, followed by two or more supplemental trains, C, of rolls, f, g, and h, arranged three or morein a set, such triplet sets being disposed for operating in continuous order throughout the trains C, and with an intermediate guideway, D, and a double-inclined platform or table, E, for accommodating the over-feed of the rod between the primary and supplemental trains; also with a suitable shifting guide or switch, D, for directing the rods of either of the trains C.

The supplemental train may be located at the foot of the over-feed table or platform, and said table may be laterally inclined; or said supplemental trains may be disposed at the ICO right and left of said table at the position indicated by the lines O2, or in any other convenient position, as desired.

The housings for mounting the rolls and the driving-gearing for imparting motion thereto may be arranged in the manner usually employed for rolling-mills or in any practical convenient manner.

In Fig. 5 I have illustrated one method in Which the triplet sets of rolls may be mounted or set up for operation when the sets are arranged in the order of a Belgian mill. The several roll shafts are geared together, as at I, the horizontal shaft being connected by gears j k lm With a driving-shaft extending along the lower part'of the frame for operating each of the four sets of rolls. For continuous order the bearings of the several triplet rolls might be supported on frame-Work extending longitudinally of the mill.

In the operation of my present form of rolling-mill the heated billet is drawn from the furnace F, and passed through the train A and through the several sets of triplet rolls, B, to its nal completion Without stopping or reheating thc rod.

Among the advantagesincident to my invention it vmay be mentioned that sets of rolls operating as triplets, or with three or more rolls in a set, carry the small rods in a better manner than do pairs of rolls, While they e'ect a more rapid reduction of the rod with less liability of forming fins thereon. Such triplet sets of rolls also permit ofthe rod being carried through faster, so that there is less liability of the small extenuated rods losing their heat before they are completed or clear of the final finishing-rolls.

I am au' are that rolling-mills have heretofore been constructed in Which a primary train operating in continuous order, supplemented by sets of rolls operating in Belgian order, have been employed, and I do not, therefore,

make claim, broadly, to such-feature, except the supplemental series of rolls are mounted in sets of three or more, eaehacting simultaneously upon the Wire rod. Neither do I herein make claim to the feature of a primary continuous train supplemented by one or more finishing trains, except the rolls are mounted to operate in triplet sets simultaneously acting at one position upon the wire rod.

What I claim as of my invention, and desire to secure by Letters Patent, is-

- 1.- In an apparatus for rolling Wire rods, the combination of a train of rolls operating in pairs, and one or more sets of rolls, each set consisting of three or more rolls,the respective faces of whiehtogether form the reducing pass of said set, said trains of rolls being disposed for operating in a continuous and supplemental manner, as set forth.

2. A rolling-mill for making Wire rods, having a leading train of rolls, A, arranged in pairs for breaking down and partially reducing the rod, supplemented by a set or sets of rolls, B, arranged to operate as tripletsA for completing the reduction and imparting the finished form and size to the rod, substantially as set forth.

3. In a rolling-mill for making Wire rods, the combination of a leading continuous train of rolls arranged in pairs for breaking down and partially reducing the rod, and a supplemental 'set or sets of rolls, B, each set consisting of three or more rolls, for completing the reduction, disposed for finishing the rod in a consecutive manner and at a single heat, as set forth.

Witness my hand this 7th day of April, A. D. 1885.

EDVIN S. LENOX.
