PROCESS OF MAKING WIRE.

SPECIFICATION forming part of Letters Patent No. 514,766, dated February 13, 1894.

Application filed October 22, 1892. Serial No. 449,668. (No specimens.)

To all whom it may concern:

Be it known that I, BENJAMIN MOUNTAIN,

a subject of the Queen of Great Britain, residing at Castleford, in the county of York,'England, have invented certain new and useful Improvements in the Manufacture of Wirenamely, a process for the manufacture of wire from metallic rings or hoops; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Hitherto in the manufacture of wire it has been customary to cast the metal in'ingots or straight pieces which have been afterward reduced to the requisite thickness by ordinary rolling and drawing; operations well understood by those in the trade.

My invention has reference to a process for the manufacture'of wire from metalic rings or hoops, whereby longer lengths of wire can be obtained than by the process above referred to, and at a reduced cost. And my said process consists in first casting the metal in ring or hoop form, then thinning the ring or hoop by rolling apparatus which reduces it in thickness while enlarging it in diameter, then cutting the ring or hoop up spirally by means of slitting or cutting up apparatus, and then passing the metal strip so produced through the ordinary wi-re drawing apparatus so that itis reduced to the requisite gage.

In the drawings, Figure 'l, is a sectional side view of apparatus for casting the metal in ring or hoop form. Fig. 2, is a front 'elevation of Fig. 1, partly in section on the line or. a). of Fig. 1. Fig. 3, is an end elevation of apparatus for rolling the rings or hoops in the manner aforesaid. Figs. 3 and 4 are detail views hereinafter explained. Fig. 4, is a side elevation of Fig. 3. Fig. 5, is a front elevation of apparatus employed for slitting or cutting up the rings or hoops combined with apparatus for reeling up the metal strip as it leaves the cutters which action also imparts motion to such cutters as hereinafter explained. Fig. 6, is a sectional side elevation of the slitting or cutting up apparatus shown in Fig. 5. Fig. 7 is an elevation of the wire drawing gage.

Figs. 1, and 2. Casting the metal in ring or hoop for-m.-A is a revolving mold (carried upon a shaft B through which it receives its rotation) having a detachable face plate 0 which is secured to the said mold by bolts D and cotters E, so that it can be readily taken off or sufficiently removed in order to take out the metal ring or hoop and replaced for molding the next ring or hoop. F is aguide trough into which the molten metal (to which is added a little salt) is poured and from p which it runs into the mold through the opening G in the plate G. The mold is revolved at a speed of seven hundred revolutions per minute, the centrifugal force keeping the molten metal equally distributed around the mold and quickly cooling it: Preparatory to pouring in the molten metal the mold is lined with ground charcoal and oil to prevent sticking of the metal.

Figs. 3 and 4:. Rolling the ring or h00p.--. A is a frame upon which are mounted rollers B and C. The roller B (which is preferably of steel) is loose upon a fixed shaft D or a stud, and is employed for rolling or operating' upon the inside of the ring or hoop B which is placed upon it. This roller B is hereinafter referred to as the interior roller. The roller 0 is fixed upon the revolving or main shaft E" and operates upon the outside of the ring or hoop, and is therefore hereinafter referred to as the exterior roller. The exterior roller is capable of adjustment in the guides K so as to regulate its distance from the interior roller as required by. the thickness of the ring or hoop being rolled, and to impart the required rollingpres'sure by means of hydraulic ram F consisting of cylinder and piston as ordinary, the pressure imparted by the said hydraulic ram F being removed when required, by means of a smaller or similar hydraulic ram G, also consisting of cylinder and piston as ordinary, and commonly called a withdrawing ram. H are guide plates for holding or supporting the ring or hoop being rolled, so as to keep such from slipping too much one way, and such guide plates are capable of being adjusted bymeans of lever J and bevel gears L. M are coupling boxes for joining the shaft E.

The mill is driven by means of engine or other shaft N upon which is a pinion O which gears with a wheel P upon the main or revolving shaft E.

In Fig. 3 is shown a sectional view of the hydraulic cylinders and pistons of the rams F and G and connections. A is the piston, B the cylinder in which the said piston works and C the hydraulic collar, which is such as is used in Brahmahs press. This hydraulic collar is U shaped, and made of leather. D is the withdrawing piston working in cylinder E and coupled to piston A by link F G is the stuifing-box. II is the inlet pipe. J the outlet pipe. These pipes are connected to a slide valve which consists of valve case K in which works the Valve slide L, which is worked up and down by means of screwed rod M (working in a corresponding thread in the top N of the valve case K and having a hand wheel O In the position shown in the drawings the inlet pipe is open and the outlet pipe closed. On screwing up the slide L the outlet pipe is opened and the inlet pipe closed. Of course the inlet pipe is con- 'nected to the accumulator from which the pressure is obtained.

In Fig. 4: is shown a plan of the mechanism for operating the guide plates H. H are the guide plates carried upon shafts H that are connected by the bevel gears L and crossshaft H One of the said shafts H has engaged to it the weighted hand lever J. On depressing this lever J the guide plates II are raised out of action. When the leverJ is in its normal position, or not depressed, the guide plates H act in the manner already explained to keep in place the ring or hoop that is being rolled. B is the top roll and B the ring in section.

Figs. 5 and 6. Sl'itting or cutting up the ring or ho0p.-A is a frame mounted upon which are horizontal shafts B and O free to revolve in their bearings. The said shafts carry cutters D and E the top cutter D being vertically adjustable, so as to regulate the cutting action, by means of handwheel F and screw Gr engaging with block H in which is journaled one end of the shaft B The said cutters are secured between face plates J and back plates K the whole being bolted together. L are guide pulleyssecured upon brackets M bolted to or cast upon the frame A". N is a separate frame (or it may form part of the frame A mounted upon which 1s a horizontal shaft 0 receiving its motion from the engine by means of ordinary driving pulley fixed upon the said shaft. The horizontal shaft 0 has a bevel wheel P which gears with another bevel wheel R upon a vertical shaft S which carries a drum or cone T at its top end and at its lower end revolves in a bush U secured upon a bracket or plate V fixed upon the machine or frame N The ring or hoop to be slitted or cut up is placed upon the lower cutter E (a portion of its edge or surface having been first started or opened by means of a pair of strong shears, such as crocodile shears). Sufficient strip is then started by the ordinary pulling in wire process to connect the ring or hoop with the revolving drum or cone T which draws the metal through the cutters, and by so doing causes them to revolve and the necessary cutting action is thus imparted so that the ring or hoop is converted into metal strips which are afterward passed through the ordinary drawing apparatus to bring the strips to the required gage of wire.

The drawing of the metal strips into wire is accomplished in the ordinary well known manner.

In Figs. 5 and 7 N" is the wire drawing gage carried in the frame N in which it is adjustable. The frame of the wire drawing gage is bolted or fastened upon the frame N as shown. The metal strip passes through this gage and is thus drawn into wire that is wound on the drum '1 as shown.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-- The process of manufacturing wire which consists in first casting the metal in ring or hoop form, then thinning out the ring or hoop by rolling it so that it is reduced in thickness and increased in diameter, then spirally slitting or cutting the ring into strips, and finally drawing the said metal strips into wire of the required gage, substantially as described.

BENJAMIN MOUNTAIN.
