EDWIN S. LENOX, OF WVOBCESTER, MASSACHUSETTS, ASSIGNOR TO THE W'ASHBURN & MOEN MANUFACTURING COMPANY, OF SAME PLACE.

MACHINE FOR COILING WIRE RODS.

SPECIFICATION forming part of Letters Patent No. 373,463, dated November 22, 1887.

Serial No. 179,478. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN S. LENOX, a citizen of the United States, residing at WVorcester, in the county of W'orcester and State of Massachusetts, have invented certain new and useful Improvements in Machinery for Making Wire Rods; and I declare the following to be a description of my said invention sufficiently full, clear, and exact to enable othersskilled in re the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification.

The object of my present invention is to 1 provide a. practical, convenient, and efficient apparatus to operate, in connection with a wire-rod-rolling mill, for taking care of a hot rod as it issues from the reducing-rolls, for depositing it in a manner to prevent tangling, and for facilitating its withdrawal for delivery to a secondary train or set of rolls for further reduction and finishing; also, to provide, in connection with said apparatus, means for maintaining or augmenting the heat of the rod; also, to afford facilities for the discharge of the rod in a coil or bundle when desired. These objects I attain by mechanism the nature, construction, and operation of which is illustrated in the accompanying 3o drawings and explained in the following description,theparticularsubject-matterclaimed being hereinafter definitely specified.

In the drawings, Figure 1 is a longitudinal vertical section of parts of a rolling-mill, with a rod-receiver and adjunct mechanism, illustrating the nature of my invention. Fig. 2 is a sectional view showing the receiver-cap and the swinging guide connected therewith. Fig. 3 is a bottom view of the top plate and swinginggnide tube. Fig. 4 is a plan view of the apparatus. Fig. 5 is a horizontal section at the position of line a; m, Fig. 1; and Fig. 6 is a horizontal section at line y y, a portion being taken below the burner-plate at line z.

In referring to parts, A denotes the primary and B the secondary train of reducing-rolls in a rod-rolling mill, which trains may respectively consist of any desired number of pairs or sets of rolls mounted and operated in the manner of an ordinary continuous rollingmill, or to work in Belgian order or in other suitable manner, as may berequircd. Thefull complement of rolls and machinery of the respective trains is not herein shown, as it is sufficient for the purposes of my invention to 5 show the final rolls a of the primary train and the leading rolls 1) of the secondary train.

0 indicates a tank, receiver, or chamber, into which the hot rod is delivered as it issues from the rolls a, and from which it may be readily conducted to the secondary rolls B. This receiver 0 is preferably formed as a eircular upright truncated conical shell, made of boiler-plate, cast-iron, or other suitable material, and sn pported in stationary posit-ion upon a suitable bed-plate, 0 that forms the bottom of the chamber and upon which the rod is deposited. At the top of the receiver, and support-ed either by the conical shell or by a separate frame, D, preferably the latter, there is an annular bearing-plate, D in or upon which is mounted a rotating cap or geared disk, D, which carries a guide-tube, d, passing through it in a vertical direction, and having at its lower end an extension or tubular guide, d, connected to the under part of the rotating disk in a manner to rotate therewith, and which guide (1' is arranged to be laterally adjustable for the purpose of directing the rod toward the side of the receiver, or to assume a position coincident with the axis thereof. In the present instance, the top of the guide d is made bell shaped and stands somewhat above the center of the rotating gear D, while the lower part of the guide d is hinged in a manner to swing laterally, and is provided with an arm that connects by means of a pivoted link, 0, with a grooved collar, E, mounted to slide on the vertical portion of the guide d above the gear D. A forked lever, E, is pro- 0 vided for working this collar E, whereby the lower portion of the guide d can be adjusted while in rotation from a position in line with the axis of the receiver-chamber to a position for directing the rod more or less toward the 5 side of the receiver.

A counterpoise, e", may be attached to the lever E; or any suitable device may be used in connection therewith for retaining the parts at positions of adjustment.

IOO

The geared disk D is preferably mounted on a series of anti-friction rollers, 0, inserted between its under surface and the bearing-plate, as indicated in Figs. 1 and 2, and it is operated by means of a gear, G, on shaft G, which connects by suitable shafts and gears, G G, with the primary train or rolls a, so that the rotation of the gear D and guide d will act to lay the rod into the receiver at a speed substantially corresponding to that at which it is delivered from the rolls a.

A clutch, K, of any suitable construction, is combined with the shafts and gearing for throw ing the rotating parts, with the disk D and guide d, into and out of action, and a handlever,K,or other convenient device is arranged for operating said clutch.

F indicates a central guard extending upward within the receiver 0 for the purpose of insuring the extension of the coils of rod. Said guard is preferably made in conical shape of a series of bars, f, with openings between them, and with a closed conical top at f. If desired, said guard may in some cases be made as a shell or solid cone, or as a cylindrical shell or body, if desired. This central guard, F, is mounted on a vertically-reciprocating standard, H, and a hydraulic or other power lifting apparatus, H, combined therewith, whereby said guard can be raised to the position shown in Fig. 1 or dropped into the chamber F below the level of the bed-plate C", said plate being made with a central opening corresponding with the size of the base of the guard-cone.

h h indicate the pipes leading to the respective ends of the cylinder H. and H is the valve devices for directing the flow for exerting power above or below the piston P for working the conical guard up or down, as desired.

w indicates the supply and w the discharge pipes leading to the valve H Within the base or foundation Lupon which 7 the receiver 0 is supported, and beneath the bed-plate 0 I arrange a gas-pipe, I, and series of Bunsen burners t, as indicated in Figs. 1 and 6. The base-plate may be provided with openings i to permit the heat to pass up into the interior of the chamber 0, from whence the hot gases can be drawn down through the openings between the guard F into the chamber F and conducted to the chimney-stack by way of the flue J. Suitable openings, 0, are formed in the base-wall for admitting air and allowing access to the burners, and suitable cocks, 1 are provided for regulating the flow of gas.

A door or pair of doors, 0*, are arranged at the lower part of the receiver 0, (see Figs. 1 and 5,) which can be opened to permit of the rod being taken out in a complete coil, if desired, by the aid of a suitable hook inserted through this doorway. Said doors are in the present instance hinged, as at t, but, if preferred, could be made to slide laterally or lift upward or to open and close in other convenient manner.

The guide M, for conducting the rod from the rol]s a to the receiver funnel or guide (1, is provided with an enlargement, chamber, or

recess, m, for the introduction of tongs for seizing the rod, and the upper portion, M, of said guide M is hinged at n, so that it can swing upward,as indicated in dotted lines, Fig. 1, and a suitable counterbalance-weight,

s, can be combined therewith as convenientfor retaining it at positions of adjustment. The pass-guidesv between the respective pairs of rolls may be of ordinary construction.

In the operation of my improved apparatus the rod as it issues from the last rolls a of the primary train is conducted by the guide M into the guide d, and thence through the tube d is delivered within the receiver 0, the part D being rotated by gear G, and the end of the tubular guide at, swinging to one side, as in Fig. 1, causes the rod to be coiled within the annular space between the central guardcone, F, and outer wall of the receiver as it falls upon the bottom plate, 0'. (See dotted and broken line L, Fig. 1.)

When the rod has all passed the rolls a, the end of the rod is seized by an attendant inserting his tongs at the space m. The top of the guide M is thrown up, and the'end of the rod is carried to the secondary train and in- 'serted in the bite of the rolls b through the bell-shaped guide'b, (see dotted and broken line 1, Fig. 1,) the lever E is raised, which swings the mouth of the tubular guide d into a position coincident with the axis of. the receiver, and the rod is drawn out of the chamber in reverse order from that at which it entered therein, so that the coils are consecutively raised and unwound without liability of tangling and without unduly straining the hot rod.

During the operation of withdrawing the rod from the receiver in the manner above described the rotation of the top D can be bar the coil can be bodily drawn out laterally through the doorway.

By making the central guard-cone, F, of bars f, with spaces between, the end of the rod on entering the receiver can fall between said bars, and thus be retained out of the way of the circular coils as they are laid in or withdrawn from the chamber of the receiver.

If desired, thereceiver C may be formed of a series of upright inwardly'inclined bars surrounded by a cylindrical shell, or hoops, in-

stead of a complete conical shell, the inner surface of said bars giving the interior a conical form substantially like the shape shown.

This rod-receiving apparatus is designed more especially to be used at an intermediate stage of the rolling operation, as shown and described; but, if desired, it may be employed as a final reel for coiling finished wire rods as they come from the rolling-mill, in which case the rod would not require to beheated. Therefore the gas-burners i may, when desired, be omitted.

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

1. In apparatus for coiling hot wire rods by delivering them from a revolving guide to impinge against the inner surface of a circular casing, the receivercase made of conoidal form and having its end toward which the coils tend of greater diameter than the part adjacent to the delivery-guide, as and for the purpose hereinbefore set forth.
