GEORGE HASKELL SCOTT, OF WORCESTER, MASSACHUSETTS.
APPARATUS FOR HEATING WIRE.
SPECIFICATION forming part of Letters Patent No. 339,219, dated April 6, 1886.
Application filed June 18, 1585.
To all whom it may concern:
Be it known that I, GEORGE HAsKELL SCOTT, of \Vorcester, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Heating Wire; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which- Figure 1 represents a side view of my heating apparatus, said figure also showing suitable reels and a tempering apparatus in connection with said heating apparatus, as hereinafter more fully described. Fig. 2 represents upon an enlarged scale a vertical transverse section through my improved wire-heating apparatus, taken on line a b, Fig. 1, looking in the direction indicated by arrow 0, same figure; and Fig. 3 represents, also upon an enlarged scale, a vertical central longitudinal section through the heating apparatus aforesaid, also showing in the same figure an ordinary reel, from which the wire is unwound prior to entering said heating apparatus.
My invention relates to apparatus for heating wire for the purpose of annealing and tempering the same; and it consists in passing the wire through a long cylinderor tube in direct contact with-burning vaporized petroleum, kerosene, naphtha, or similar inflammable fluids contained therein, said vaporized fluid being supplied to said cylinder-or tube and the combustion controlled by suitable means, as hereinafter more fully described.
It also consists in the combination of said heating or annealing apparatus with the ordinary apparatus of reeling and tempering wire.
To enable those skilled in the art to which my invention appertains to make and use the same, I will proceed to describe it more in detail.
In the drawings, A represents the heating apparatus; B, an ordinary reel from which the wire d is unwound prior to entering the heat ing apparatus aforesaid; O, a tempering apparatus, and D a reel for coiling up the finished product.
As said reels and tempering apparatus are of the usual well-known construction and ar- Serial No. 169,027. (No model.)
rangement, a detailed description of the same will be unnecessary in the present instance.
The wire to be treated may be annealed only by passing through the heating apparatus A, and at once coiled up, or it may be both annealed and tempered prior to being coiled by a continuous operatiomas shown in Fig. l ofthe the drawings. It is heated in the apparatus A by passing through a long cylinder or tube, 6, containing burning vaporized petroleum, kerosene, naphtha, or similarinflammable fluids. Said cylinder or tube is arranged longitudinally in the center of the upper part of the apparatus. It projectsashort distance beyond the outer casing, f, and has contracted end openings of the proper size to admit of the wire passing freely through them, and at the same time prevent the escape of the burning flame within. The products of combustion generated in theheatingtube epass offth rough a flue, 9, connected therewith. Said tubeeis inclosed and supported in a [ire-brick casing, h, resting on a horizontal iron plate, 1', which extends over the whole size of the apparatus, and is in turn supported at the edges thereof by the outer casing, f. A division is thereby formed between the upper part of the apparatus, containing the inflammable fluid under co mbustion,and its lower part, where said fluid is stored, as hereinafter described.
Portions of the fire-brick casing h are left open, as shown at the points h, for the purpose of providing a means whereby the ends of the supply-pipes and their regulating devices may be conveniently reached from the outside of the apparatus. The side ol'the outer casing-,f, corresponding therewith is also provided with openings for the same purpose.
The supply of vaporized fluid is admitted to the inside of tube 6 through a suitable number of openings, 6, formed in the side thereof, as shown in Figs. 2 and 3. In this instance I have shown four of such inlet-openings; but, if desired, a greater or less number may be employed, to suit different requirements.
I have represented in connection with each of the inlets e of the tube 0 a device for vaporizing the fluid used similar to an ordinary atomizer used for toilet purposes, the fluid j, contained in the reservoir k, being drawn up through the pipes l and vaporized as it passes out at their upper ends by forcing a strong steady current of air or steam across said upper openings through the branch nozzles m of the main air or steam supply pipe a, said steam or air also facilitating the process of combustion in the tube e. To-further facilitate said process of combustion, I extend the supply-pipe at up through the exhaust smokeflue 9, thereby heating the air or steam contained therein before being expelled from the nozzles m, as aforesaid, thus at the same time utilizing the waste heat of the apparatus in addition to the above-described advantage.
The reservoir is, which in this instance is made round in cross-section, as shown in Fig. 2, is supported alittle above the bottom of the apparatus, and is surrounded with a body of running water, e", which enters through the pipe 0, near the bottom of the apparatus, and flows out of the pipep, upon the opposite side of said apparatus, a short distance above the level of the top of the reservoir. By thus surrounding the inflammable fluid j with cool running water there is but little if any danger of its igniting from the heat produced above in the tube 6, hereinbefore described, and to further reduce the liability to danger from the above cause openings q are formed on opposite sides of the outer casing, f, just under the horizontal plate 6, thus admitting of a free circulation of cool fresh air between said plate and the top of the water surrounding the inflammable fluidj in the reservoir 70. Said fluid j is supplied to the reservoir through a suitable inlet-pipe, 1*.
By increasing or decreasing the number of inlets e in tube 6 and the atomizers connected therewith the degree of heat around the wire passing through said tube may be correspondingly regulated. The degree of combustion may also be regulated more or less by opening or closing valves 8, interposed between the nozzles m and air or steam supply pipe 02, more or less of the inflammable liquid j in res ervoir It being drawn up, according to the volume and velocity of the air or steam current across the top openings of the pipes l.
The valves 8, which may be of ordinary wellknown construction, are operated by means of the hand-wheels t on the outer ends of the rods u, whose inner ends are connected with said valves.
The tube 6 may be made of metal, as shown, or any other suitable materials.
Those skilled in the art to which my invention appertains will readily perceive from the foregoing description and the accompanying drawings that by its application to practice many objectionable features are entirely removed.
By simply turning on the air or steam pressure in the manner hereinbefore described and lighting the vaporized fluid the apparatus is in a very few moments under full blast with the flame at its maximum heat, while at the same time being under perfect control of the operator. After the work in handjs completed the operator then turns off the pressure aforesaid, when the expense ceases, thus not only economizing in fuel, but also saving unnecessary burning out of the apparatus.
Another advantage of my improved apparatus is that the quality of the wire thus heated is much superior to that produced by the usual methods employed, especially when lead is used, which often contains more or less impurities injurious to iron and steel, thus causing the production of much wire of inferior quality.
Having described my improved process for heating wire, what I claim therein as new and of my invention, and desire to secure by Letters Patent, is
1.,In a furnace for heating wire, the outside casing, f, having the horizontal divisionplate *6, and side openings f q, the fire-brick casing h, provided with side openings 71., and chimney g, in combination with the horizontal tube e, having openings at both ends thereof and provided with side openings 6, the conducting-pipes], reservoir k, and supply-pipes n, provided with nozzles m, and ordinary regulating-valves, s, all constructed and arranged substantially as shown and described.
2. The combination of the reels B D, the outside casing, f, having the horizontal division-plate i, and side openings f q, the firebrick casing h, provided with side openings h, and chimney g, with the horizontal tube 6, having openings at both ends thereof and provided with side openings 6, the conductingpipes Z, reservoir is, and supply-pipes n, provided with nozzles m, and ordinary regulatingvalves, 8, substantially as and for the purposes set forth.
