UNITED STATES PATENT OFFICE.
DUBOIS D. PARMELEE, OF NEW YORK, N. Y., ASSIGNOR TO THE OKONITE COMPANY, .OF SAME PLACE.
APPARATUS FOR COVERING WIRE W lTH PLASTIC MATERIAL.
SPECIFICATION forming part of Letters Patent No. 429,581, dated June 3, 1890.
Application filed March 13, 1890- Serial No. 348,755. (No model.)
To all whom it may concern:
Be it known that I, DUBOIS D. PARMELEE, of New York city, in the county and State of New York, have invented a new and useful Improvement in Apparatus for Covering Wire with Plastic Materials, which improvement is fully set forth in the following specification.
This invention has reference to the con struction of apparatus for use in covering wires or like articles with a sheathing or tube of lead or other soft metals or alloys thereof or other plastic or semi-plastic substances. The most convenient mode of manufacturing such articles as lead-covered wire is by the use of a properly-constructed press operating on the principle of the lead-pipe press. Many apparatus or machines have been heretofore devised for this purpose. Their essential parts are a reservoir for the soft lead, a ram, a core-tube for conveying the wire into the reservoir, and a concentric die for forcing the lead around the wire.
The object of the present invention is the construction of an efficient apparatus independent of any particular press, but which may be readily connected with or disconnected from a press or jack of any suitable kind. Such apparatus contains in compact form all the devices necessary for applying the sheath of soft metal or other substance around a wire, and avoids the necessity of a specially-constructed pipe-press. Its appli cation to and use in connection with an ordinary press do not impair the usefulness of the latter for ordinary purposes.
In the accompanying drawings, which form part of this specification, Figure I is a perspective view of the apparatus. Fig. II is a central vertical cross-section, and Fig. III is a sectional plan on the line A B, Fig. I.
E is a steel crucible.
F is the lid or cover of the crucible, fastened by steel bolts G. On one side of the crucible is a flange or projection h, into which a pipe I: is screwed. There are also two flanges Zm projecting from the crucible directly opposite or in line with each other, as shown in Fig. III. At the top of the crucible is a flange n, Figs. I and II, which rests upon the drawings.
a corresponding flange p of a cast-iron case or cylinder. '2", to which it is fastened by bolts 25. At the bottom of the case is a flange a", which is bolted'to a cast-iron base by bolts '11.
Into the flanges Z m, Fig. II, of the crucible are screwed tubes to and y, which reach within the crucible and taper inwardly, as shown in At the end of each of these tubes and within the crucible is a steel die. These dies are designated a: and z, respectively. (See Fig. III.) The die or tip 00 is screwed into its tube, while the die 2 is held in position by a taper and flange.
In the caser is a door 8, openingto the space below the crucible. At the top of the case, on a line with the top of the crucible inte riorly, are apertures a for the passage of the products of the fuel used for heating the crucible.
The outer end of the tube has screwthreads, as represented in all the figures, for attachment to a cistern or reservoir of melted or plastic metal.
In operationfor example, to incase an insulated wire with lead the wire is passed into the tube to, Fig. III, through the die 00, l
which it closely fits, and then into the die 2 of the tube y. than the die x as the thickness of the caseor tube of metal required. The plastic metal or alloy, so rendered by proper regulation of its temperature, is forced into the crucible through the pipe 70, filling it, and then it is forced into the space between the die z and the wire inserted in it. It carries the wireby adhesion through the tube 'y outwardly and continuously to a suitable reel, precisely as long practiced in the manufacture of lead pipe. The feeding of the wire to the tube 10 is most conveniently done from a reel. The temperature of the crucible is governed by the heat from a portable charcoal-brazier, a Bunsen burner or oil flame placed through the doors under it, and by a cold blast of air from any form of suitable blower when the temperature is to be lowered.
A reservoir or cistern of melted metahprovided with means for exerting sufficient pressure on its surface, is required; but as such apparatus is common and forms no part of the This die is as much larger present invention it is not shown. To this reservoir, near the bottom, is screwed the pipe 76, which leads to and enters the crucible E, Fig. III.
An ordinary hydraulic lead-pipe press may be used by simply entering the pipe in at the side near the bottom of the lead cylinder and closing aperture for the dies of the cylinder Without impairing its Value for ordinary use, as when the press is desired for its regular use the pipe 7a is detached and a solid rod or tap-bolt is screwed in its place.
The dies 00 .2, Fig. 3, employed in the tubes w y of the crucible correspond with the size of the wire or cable to be covered and the thickness of the metal required. These dies may therefore be changed by removing the tubes 10 y from the crucible and inserting the proper pair, as occasion may require.
The shape of the dies found best in practice is clearly shown in Fig. 3.
I claim as my invention- An apparatus for covering wire with a sheath of plastic material, said apparatus being separate from and independent of any particular form of press and comprising a crucible flanged and bolted to a supportingcase, the core and die tubes screwed into the crucible with their axes concentric and having each at its inner end a removable die or tip, and a third tube with its axis at an angle to the first-named tubes, said casing being adapted for the introduction of heating or cooling agents, substantially as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
