APPARATUS FOR GOVERING WIRE WITH SOFT METAL.

SPECIFICATION forming part of Letters Patent No. 374,166. dated December 6, 1887.

Application filed April 26, 1887.- Serial No.236,l59. (No model.)

To @ZZ whom it may concern:

Be it known that I, J. CHARLES APPLEBY, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and luseful Improvements in Means for Covering Wire Cables, Vire, dsc., with Lead, Alloy, Soft Metal, or other Plastic Material; and I do hereby declare that the following is afull, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use' the same.

This invention is more particularlyintended for covering wire cables, comparatively stili' wire, &c., with lead, alloy, soft metal, or other plastic material, with t-he object of avoiding the necessity of giving sharp bends or curves to the cable or wire, as the case may be. Said invention may, however, be employed for coverin g cables or wire of more flexible character, if desired. It may, further, not only be used for coveringsuch articles with lead, alloy, or

vother soft metal, but also forcovering metallic cables, wire, Snc., with any suitable plastic material, either for the purpose of electrically insulating the same or for the purpose of protecting the same from external injury.

One feature of my said invention is, furthermore, also intended to permit one and the same set or system of covering devices to be employed upon cylinders varying in diameter, thereby enabling` one of such set or systenis to be employed, as occasion may require, upon one or another of several cylinders of differing capacities.

My invention comprises certain novel combinations of parts, whereby the objects aforesaid are effectuall y secured.

Figure l is avertical transverse sectional view taken in the line am of Fig. 2, representing an apparatus embracing my said invention. Fig. 2 is a side view and partial sec tional view taken in a plane atright angles to Fig. l of said apparatus. Fig. 8 is a plan View of the same.

At A and B are represented, respectively, the upper part of the cylinder, in which is placed the material with which the cable or wire is to be covered, and the piston or plunger, actuated by hydraulic or other suitable power, by which said material is ejected from C is the head, to which is provided, as here-` inafter explained, the devices by which the covering material is placed upon and around the cable or wire. This head C is firmly secured upon the end of the cylinder A by any g suitable means-as, for example, by transverse bolts a, passing through coincident holes in lugs on thehead C, and lugs c, secured tothe side of the cylinder A. Any other preferred means of securing the head C to the end of the cylinder may be employed.

Upon the inner end or surface of the head C are provided annular ribs orsplines c,which may be two or more in number, and which, when the head is in position upon the vcylin` der, shouldbe concentric with the longitudinal axis of said cylinder. When the head C is in its place upon the end of the cylinder, one or more of these ribs or splines e iit into corresponding groovcs'f, formed in the contiguous end of the cylinder and concentric with the axis ofthe latter.

By providing several cylinders of different diameters, but each with a system of grooves, f, which have the saine radius and a similar cross-section with the corresponding ribs of the head C, the head C may benscd at will upon any of said cylinders. With a cylinder of smaller diameter the innermost of the ribs e will be within the line of the internal walls of the cylinder, but the outermost of such ribs will fit into the grooves of the corresponding radii in such cylinder, so that within certain predetermined limits one cylinder head C may be used with several cylinders.

The head C has at one side an inlet-passage, g, and at the opposite side, preferably higher than the inletpassage g, is an outlet-passage, This outlet-passage 7c may be placed lower down or higher up, so long as its relation with the inlet-passage g is such thatthe cable or wire (indicated at D) is not bent to a degree sufticient to bring the cable or wire entering and leaving through said passages to a right or acute angle, it being the object of the fea ture of the invention now under consideration to enable the cable or wire to be covered without bending the same to any considerable degree. linterposed between the inlet-passage g IOO and the outlet-passage 7c is an annular die, E, which is preferably externally threaded, so that it may be held in place by being screwed into a xed nut, m, suitably provided in the head C. A tubular core, F, is in like manner inserted between the inlet-passage g and the outlet-passage r, and behind the annular die E. The space n, between the apex of the tubular core F and the annular die E, determines the thickness ofthe covering placed upon and around the cable or wire D in the operation ot the apparatus, and a space, r, around the tapering or conical portion of the tubular core F, behind the annular die E, communicates by passages G With the interior of the cylinder A, said passages joining the space r at opposite sides of the tubular core F, so that when the lead .or other soft metal or plastic material in said cylinder' is forced outward by the piston or plunger B it passes through the passages G into the annular space or chamber 1, and thence between the apex of the tubular core F and the annular' die E, and around and upon the cable or Wire D simultaneous with such passage of said cable or wire. Said cable or Wire, as the case may be, is covered by or inclosed Within the plastic material, Which,in effect, forms a pipe or tube around the same.

In order that the cable or wire D may pass readily to and through the tubular core F and annular die E, the head C is chambered adjacent to the inletpassageg to provide room for a pulley or roller, I, the circumference of which is preferably grooved, and which is arranged in such relation to the inlet-passage g as to guide the cable or Wire D While the same is passing through theinlet-passage g into direct and due relation with the tubular core F, thereby insuring the proper transmission of the cable or Wire D through the tubular core and the annular die, and also preventing any undue friction upon the cable or Wire as the same is guided to the tubular core and the annular die, as explained.

By means of my invention, therefore, I am enabled to cover cables, comparatively stiff Wire, and the like without subjecting the same to short bending, which in sorne eases is almost impraeticable, and in others-as, for example, in covering with lead or other soft metal Wires already provided with a covering of gutta-percha or other insulating material-is liable to injure such covering or insulaling material. I am also enabled to effectually cover such relatively stiff wire or rigid cables or Wires Without undue friction upon their surfaces or upon the insulating covering with which they may be already protected. Furthermore, as the annular die E and tubular core F may be readily replaced by others of different internal diameters or proportions, and inasmuch as the head C may, as hereinbefore explained, be used upon cylinders of different capacities or provided with pistons worked With different power, I ani enabled by the use of one and the same head C to employ cylinders of different capacities, power, 5cc., as occasion may require, in the production of covered cables, wires, Ste., of different diameters, different thicknesses of covering, 85e. I am, furthermore, enabled to adjust one and the same head upon such cylinder, as the exigencies of the case may require. Any suitable means may be employed for maintaining the contents of the cylinder A at the temperature best calculated to secure the required degree of plasticity, and in like manner any suitable means may be employed to prevent the head C and the parts carried thereby from becoming overheated.

The die E, instead of being of a true annular form to cover'cylindrical Wires, cables, Src., may be oi' any other suitable shape to' conform to that of the cable, Wire, or other article to be covered. Thus, Yfor example, for a cable more or less flattened the die would be of elongated shape, the general contour of the die corresponding to that of the crosssection of the cable, wire, or other article to be covered. It is therefore to be understood that the term annulan as employed in this specification and the claims thereof, is sufficiently comprehensive to include dies circular, oblong, cruciform, rectangular, or other in their contour.

lhat I claim as my invention isl. Ahead for the cylinders of wire-covering machines provided with an annular die, E, a tubular core, F, and suitable passages for the transmission of the cable or Wire to be covered and for the inoW of the covering mate- IOO rial to the die, and constructed with a plurality of annular ribs e, all substantially as and for the purpose herein set forth.

2. In an apparatus for covering Wire, the combination of a cylinder having substantially a plain face at its open end, a head provided with a passage and connected With the opening of the cylinders, and with a coveringforming die within the head, and a rib or ribs surrounding the opening of the cylinder and serving to prevent thelateral escape of the covering material, and mechanism for fastening said covering-head upon the end of the cylinder, substantially as described.

3. rIhe combination, in a wire-covering machine, of a removable head, C, containing passages 'for the Wire to enter and leave said head, the core F, surrounding the Wire, the die E, serving to determine the size of the covering ot' the wire, the passage G', and the rib or ribs c for making a joint between the cylinder A and head C, substantially as described.
