APPARATUS FOR COVERING WIRE WITH SOFT METAL.

SPECIFICATION forming part of Letters Patent No. 374,164, dated December 6, 1887.

Application filed March 1 5, 1887.

T0 aZZ whom it may concern:

Be it known that I, J. CHARLES APPLEBY, a citizen of the United States, residing at J ersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Covering NVire with Lead, Alloys, Soft Metal, or other Plastic Material; and Ido 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.

This invention is more particularly intended for covering insulated electric wires with lead, alloys, or other soft metal or plastic material; but it may also, when desired, be used for other and analogous purposes.

The said invention comprises certain novel means whereby by the simple adjustment of certain parts pipes having walls of variable thicknesses, but of substantially the same internal bore or diameter, may be made with one and the same apparatus; and it also comprises certain novel means whereby the operation of covering the wire with a substantially uniform covering of lead, alloy, soft metal, or other appropriate material may be conducted with very great rapidity and convenience, and with but moderate outlay of time and labor, the said invention being especially adapted to the covering, 'as aforesaid, of considerable lengths of wire with greater speed than has heretofore been attained.

- Figure 1 is a side elevation of an apparatus illustrating in part my said invention, and Fig. -2 isa horizontal sectional view taken in Fig. 3 is an inverted plan view, on a larger scale, of the ram-head,

the position of which in the machine is indicated in Fig. 1.

Fig. at is a view of the other or opposite end of said ramhead. Fig. 5 is a vertical transverse sectional view taken in the line 2 z of Figs. 4, 6, and 10. Fig. 6 is a vertical transverse sectional view taken in a plane atright angles to Fig. 5t hat is to say, in the line 3 y of Figs. 4, 5, 9, and 10. Fig. 7 is a detail view, on a larger scale, of certain parts shown in Figs. 5 and 6; and Fig. 8 is a like view as seen in a line of sight at right angles to Fig. 7. Fig. 9 is a side view of the rain- Serial No. 230,971. (No moilcl.)

head, and on the same scale'as Figs. 3, 4, 5, 6, and 10. Fig. 10 is a horizontal sectional view of the ram-head, taken in the line 0 o of Figs. 5 and 6. Fig. 11 includes two detail views,taken in lines of sight at right angles to each other, of certain parts shown in Figs. 5, 6, 7, and 8. The location of the rarn-head and its adjuncts with reference to the other parts of the apparatus is represent-ed in Figs. 1 and 2.

A is the cylinder or receiver, in which is placed the lead, alloy, or other soft metal .or plastic material with which the wire is to be covered or coated, and B is the rain, the head 0 of which passes down into the cylinder or receiver A.

D is the fixed head from which the ram B is suspended, and which is connected by suit able tension-bars, E, with the hydraulic press, the upper part of which is shown at F.

The several parts just hereinbef'ore indicated may have, with the exceptions hereinafter particularized, the same construction as an ordinary lead-pipe-niaking machine, or, as it is commonly termed, a leactpipe press, and are to be operated in substantially the same manner. ment, and operation of the said parts may, however, be varied at will, so long as the principle of my invention, as hereinafter set forth, is preserved. It is of' course to be understood that in the construction hereinbefore set forth the cylinder or receiver A moves toward. the ram B, in order to insure the passage of the latter into the said cylinder, in the man ner'usnal in leadpipe machines or presses.

The construction, arrange- The head 0 of the ram B, or, as I term it for as in an ordinary lead-pipe machine or press,

has adifferent construction, more clearly illustrated in the larger views of Figs. 3 to 6, inclusive, and also of Figs. 9 and 10;

\Vhen the apparatus is designed to simply cover one wire at atime, only one series or system of the devices, hereinafter set forth, need be embodied in the ram'head; but it is preferred to coat or cover two coated wires simultaneously, and therefore, as represented in the drawings, duplicate systems or series of such devices are shown. WVhen preferred, the

number of such systems or series may be still further increased in order to simultaneously coat or cover a larger number of wires.

Each system or series of devices is constructed and arranged as follows:

In the outer part of the ram-head O is inserted a circular die, a, as more fully shown in Figs. 5 and G. This die is provided with an external screw-thread, which screws into a fixed nut, b, suitably provided in the ramhead. A circumferential flange, c, integral with the die, is arranged in due relation with a suitable flat bearing, d, and one or more washers, e, are inserted between the flange a and the bearing d, for the purpose hereinafter set forth. The throat a of the die a is preferably of tapering or conical form and smallest at its outer end.

Formed in the ran1-head, and extending from theface thereof to and behind the throat a of each die a in such manner as to permit the lead, alloy, or other soft metal or plastic material, as the case may be, to pass from the cylinder to and out from the said throat a of the die, are passages f. The outer ends of these passagesf are enlarged or flaring, as shown more fully atf in Fig. 3, and the face of the ram-head adjacent to said flaring ends of the passages f is cut away, as represented atg in the cross-section, Fig. 6, in the inverted plan view of Fig. 3, and in the side view of Fig. 9, and when more than one die is used in one and the same ram-head the edge portions 9 are cut away, as illustrated in Figs. 3 and 9, to facilitate the ready entrance of lead alloy or other soft metal or plastic material from the cylinder to the passages f, as

just hereinbefore explained.

Inserted in the ram-head is a tubular guide, It, said guide being preferably provided with an external screw-thread, by means of which it is screwed into a fixed nut formed in the ram-head. The bore of this tubular guide h is extended within the center or axis of the throat to of the die a, and the end of the said guide adjacent to the die is of tapering form. The annular space 3 between the tapering end of the tubular guide h and the inner surface of the die a determines the diameter and the thicknesses of the walls of the pipe as the same is formed around the wire to be covered. The ram-head is recessed, as shown at m, affording space for a wheel, 72, rotating on a journal or axle, T, which is also indicated in dotted outline in Fig. 5. The wheel a is so arranged that a line drawn longitudinally and centrally or axially through the throat or of the die a and the bore I) of the tubular guide his at substantially a tangent to the circumference of the wheel a. The latter should be circumferentially grooved, as shown in Fig. 5. The recess m opens to the opposite end, m, of the ram-head. The wire to be coated passes over the pulley or pulleys w w, as shown in Fig.

1, thence inward around the wheel a, thence outward through the tubular guide 71. and the throat a of the die a, thence to the pulleys 10 w to a suitable reel or other apparatus for receiving the same. When the inlet to the recess m is at the side of the ram-head, as indicated at a in Fig. 6, the location of the pulleys w 20 will be correspondingly changed. The lead, soft metal, alley or other plastic material, being placed in the cylinder A, with the wire to be covered passed around the wheel a and through the guide h and the die a, as explained, the cylinder ismoved wit-h relation to the ram head to eject the lead, alloy, soft metal, or other plastic material through the flaring ends f of the passagesf to and through the space t between the tubular guide It and the die a, and thence out in the form of a pipe surrounding the wire to and over the receiving-pulleys w 10 the action of the lead, alloy, soft metal, or other plastic material as it issues from the throat a of-the die a carrying with it the pipe, the wire being of course inclosed within the pipe and carried thereby.

In order to guide the wire, the latter being indicated by the reference-letter 8, into the requisite relation with the wheel 12, a fixed guide, t, is arranged in due relation with the inlet-opening m of the passage m.

The ram head, for purposes hereinafter set forth, is provided at any suitable part with a recess or cavity chamber, m separate from v the recess m,- but in practice it is preferred to make the said recess m of a size sufficient to serve the said purpose in addition to that hereinbefore explained. Within the cavity, whether a separate one or the recess m aforesaid, is placed a vessel, B, preferably made of sheet-copper, and preferably having a flange, c at its upper end, which rests upon the ram-head, as illustrated in Fig. 6, and serves as a support for the vessel B. This vessel B is provided with an inlet and outlet pipe or passage-as, for example, an inlet-pipe, a, and an outlet-pipe, b*through which cold water or any other suitable refrigerating fluid may be circulated, so that the said vessel, being placed in suitable contiguity with the metal of'the ram-head, cools or reduces the temperature thereof to the extent required to prevent the liquefaction er undue fluidity of the lead or other soft metal, alley, or plastic material as it passes to and through the die a.

By means of my said invention, herein set forth, I am enabled to coat wire with any suitable plastic material or with any suitable material. in a plastic condition. The invention may also, when desired, be employed for covering cables, so termed, as well as single wires, especially when the cables are of small diameters. WVhen desired, the lead, alloy, soft metal, or other plastic material may be heated to insure the requisite degree of plasticity by heat applied externally to the cylinder, either by means of a suitable furnace or by circulating hot air, gaseous products of combustion, &c., around or in contact with said cylinder in any suitable manner, or by raising the temperature of the cylinder by other appropriate means. For this purpose I have shown in Fig. 1 two braziers, A", one placed at the top and one at the bottom of the cylinder A.

The object of securing the die a in its nutseat I) is to permit of the adjustment of the die longitudinally with reference to the tubular guide and to the passages f, to increase or diminish the space between the external curved Walls of the said tubular guide and the throat or of the die when it is desired to increase or to diminish the thickness of the walls of the coat-' ing. In this adjustment the packing-washers d cooperate with the die-flange c to maintain the seat at this point between the threaded walls of the die and its seat.

I do not claim herein theinvention described, claimed, and shown in my application filed November 1, 1886, under Serial No. 217,675.
