MACHINE FOR COVERING WIRES, CABLES, &c., AND FOR MAKING TUBING' AND CORD.

SPECIFICATION forming part of Letters Patent No. 441,808, dated December 2, 1890.

Application led August 30, 1890. Serial No. 363,513. (No model.)

To all whom ii; may con/cern:

' Be it known that we, VERNON ROYLE and JOHN ROY LE, J r., both of the city ot' Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Machines for Covering Wires, Cables, &c.,and for Making Tubing and Oord, of which the following is a specification, reference being had to the accompanying drawings.

This invention is especially applicable tothe covering of telegraphic conductors of various kinds, as wire or cables, with insulating compounds of a plastic nature or capable of re-` duction to a plastic condition, but is also applicable to the covering of other bodies with such materials and to the manufacture of tubing and cord of such material.

A machine embodying our invention consists, generally speaking, of a press and a die of a form and size corresponding with those of the exterior of the covering or body to be produced, and when intended for the covering of a wire or body or the manufacture of a tube it includes, also,a thimble or core corresponding with the exterior of the wire or body to be covered or with the interior ot' the tube to be produced.

XVe will first describe in detail a machine for covering telegraph-cables embodying our invention, and will afterward point out its novelty7 in claims. l

Figure 1 represents a central longitudinal vertical section of the machine. resents a plan of the same, mostly in section, the section being taken in the line afan of Fig. l. Fig. 3 represents a horizontal section of part ot' the machine in the line azof Fig. 1. Fig. et is a plan or end view of the die which gives form and dimension to the exterior of the body or covering produced by the machine. Fig. 5 represents a transverse section of the machine, taken in the lineyg/ of Figs. 1 and 2. Fig. 6 represents a transverse section in the line 13 13 of Fig. 1. Fig. 7 is a face view of a plate which is interposed between the body and head of the press. Fig. 8 is a transverse sectional view illustrating a modification of the press-body. Fig. 9 is a plan corresponding with Fig. 8 of the press-body, partly in section in the line 12 12 of Fig. 8.

Similar letters of reference designate corresponding parts in all the figures.

Fig. 2 rep-` A and g designate the press-body, consisting of the cylindrically-bored trunk having a feeding-hopperA, andB is the feed or pressure screw fitted to said trunk, said trunk and screw constituting the principal elements of the press, which is substantially like the press represented in our Letters Patent No. 325,303, dated September 1 1885, and like other presses for similar purposes, except as to the provision for heating and cooling it, which will be hereinafter fully described.

O is the press-head containing the die D and the core E, the axis of the die and the thimble or core being arranged in the same plane with the axis of the press-body, but perpcndicularly thereto. This press-head is secured to the body by bolts a outside of the latter, passing through lugs in the body and head. In order to provide for adjusting the said head with the axis of the die and core to receive the changeable die D and is bored f through the opposite side in line concentrically with said die to receive the core-holder E', into which the changeable thimble or core E is represente-d as screwed at c, Fig. 1. This holder passes through a stuffing-box l) on the opposite side of the head to the die and is packed tightly around its exterior within said box by means of compressible packing-rings c and a gland c. These packing-rings also assist in rigidly securing the core-holder E', yet permit its longitudinal movement.

To provide for the adjustment of the thimble or core forward or backward within or relatively to the die, the said holder is fitted with an externally-screwed socket CZ, which screws into a female thread in the gland c. This socket is secured to the core-holder so that both move longitudinally together by means of a split clamping-collar d', which is ICO clamped tightly on the rear end of the diecore-holder Without turning it, the screwed socket cl `is fitted loosely to the holder and is attached to the clamping-collar d by means of a ring cl3, which is secured to it by screws d4, and which enters a `roove in the said collar. When the socket d is screwed into or out of the gland, it turns on the collar CZ and coreholder E', and so moves the said holder forward o r backward without turning it.

In the machine represented, which, as hereinbefore mentioned, is for covering cables, not only the thimble E is hollow, but also the ,holder E to permit the passage through them of the cable, the interior of the thimble being just large enough for thecable to pass through; but for making tube a solid core might be substituted for thc hollow core or th'imble E.

vlnzeither .case the exterior of the core or thimblefmight be made taper, and so may the entrance to the die, so that by the longitudinal adjustment olf vthe core-holder the annular space between the core or thimble and the dielmay be varied, :according to the required thickness of the covering of the-cable or of the walls ofthe tube.

In order to provide for the substantial support ofthe core-holderE against the pressure ofthe plastic substance forced into the head C by the press-screw, the head has constructed integral with it an internal socket C', which projects into the cavity of the said head beyond the center thereof, as shown in Fig. l, and from the back of the said socket there is a rib-like lprojection of the solid metal, as shown at c2 in Figs. 1 and v2 and in dotted Alines in Fig. 6, for the furtherand higher supv.portfof' the core-holder, the said projection e2 j being tapered upward, as shown by the dotted lines'in Fig. G, to permit the plastic material to '.passmore freely over it behind the core and vinto the die.

The'die D is representedas fitted tightly into a socket or holder D for the purpose of `facilitating the use of dies of different sizes, which maybe fitted to the same holder in -suchimanner as to be interchangeable.

To `provide for the positive concentric adjustment ofthe die and core, we prefer to Amake the dielaterally adjustable relatively tolthe core, instead of making the core adjustablerelatively to the die, as has heretofore .been done, because by that means we are enabled to support the core more rigidly against the lateral pressure to which it is subject 'and to preserve a tight joint between the adj ustablecore-holder and the head at the base of said holder. This adjustment is provided for in the following manner: The base ofthe-die-holder D is flat and it has aflange f, which is beveled on its outer side at an angle of about forty-five degrees to the base, as shown in Fig. 1, and in this beveledflange are notches f', as shown in Fig. 4. Theliat base of the said die-holder is supported upon or against the flat bottom or back of a recess f2 provided in the press-head, the said recess being wide enough for the adjustment of the die-holder in all directions laterally therein.

Through the walls of this recess are screwed adj Listing-screws f3, which have such. an inclination-as to press upon the beveled outer face of the flange f perpendicularly thereto. The screws applied in this way serve the twofold purpose, rst, of holding the die-holder firmlyin place when all screwed up tight, and, second, of adjusting the said holder to bring the die concentric with the core by screwing outward one or more of the screws and screwing inward another or others. By slackening all of the said screwsfs the die-holder is left free to be turned to bring its notches f opposite the screws, which permits the holder and the die init to be taken out whenever desirable.

To provide a jacket for the .heating `and cooling of the Vpress-body andthe screw .B'by the circulation through the press -body .of steam, Water, or other heating or cooling Huid, the outer shell A of the body, whiclris of castiron, has cored in itacirc-uitouspassage or jacket i, the inner walls of .which are .formed 'by a cylindrical bushing g,.of drawn-steelstiling, fitted and expanded into the shell A. Thesaid bushing,which contains the :boreto which the press-screw B is Afitted, ,is .represented as also entering into andcentering a plate F between the body and theheadC-and a cylindrical hub G, kbolted onto the back of the body by bolts h, the said hub G alsoserving another purpose, to be hereinafter described.

'lhe jacket or passage t', as shown yin iFigs. l, 2, and 5, is formed in the shell Aby a series of internal.annularflanges i', into which `the bushing lits tightly, and a longitudinal rib 712, connecting all of the said.flanges,.anopening '113 being formed through eachliange, first in one flange on one side of the lsaid rib-z'2 and then in the neXt {iange on the other side of the said rib, and soonalternatelythrough the whole series, the inlet -opening being at i* near one end of the body, and the outletopening being near the other end ofthe body, as shown in Figs. 1,2, and 5. The-outlet-opening and outlet-pipe i are also shown in Fig. 5. Near the outlet-opening therefis a partition l0, (shown in section, Fig. 5, and dotted in Fig. 2,) which only extends from the last flange t" to the end of the press-body, and which forms the end of the passage t', the only outlet from which is at the bottom at 5, as before described. l

For the purpose of draining the watervot condensation from the bottomsof the `several annular channels between the flanges t" L" of the jacket when steam is used as a heating medium, we make holes through the several flanges near the bottoms thereof-andinsert through the said openings a horizontal pipe o, (see Figs. l and 5,) which is open-along A its bottom. Through this pipe all the channels are drained into that onefin which the outlet is situated. To drill the said holes in the flanges t' and insert the pipe o, aflole IOO IIO

4- hole is lugged n with a screwlu T o as P er D D s i y val ves.

shown in Fig. 1. The heating or cooling fluid arrives at the inlet i4 through a chest I, bolted by bolts I onto the top of the shell A. This chest is shown in section in Figs. 1 and 3. It has two compartments j j', the former for heating fluid, as steam, and the latter for cooling fluid, as water, the separate fluids being supplied to the respective compartments by pipes j* jl, furnished with stop- The two compartments j j are in communication with each other by lateral openingsj2 jz* in their partition, and from the Aopening t7'2 is a passage la to the jacket-inlet "i4, as shown in Fig. 1, which will conduct either the heating or the cooling fluidinto the jacket, according toiwhich of the stop-valves in the pipes j* j'* is open. This construction of the press-body with a passage in the interior of the shell and a bushing which forms the inner wall of said passage and combines with said passage to form a jacket enables the said wall of the jacket which is next the bore and feed-screw to be made much thinner than is possible in a press-body in which the jacket and bore are cast integral with the outer shell, and therefore the said construction 4enables Vthe heating or cooling fluid to be brought as near as practicable to the compound that is being worked in the press, with the result that any change required in the temperature may be morequickly effected.

From the opening j2*, before mentioned, in the chest I (see Figs. 1 and 3) there is a passage la', which communicates through a passage 7a2 (see Figs. 1 and 5) in the press-body A with a concentric annular groove Z (see Figs. 1, 2, and 7) in the face of the plate F, hereinbefore described as interposed between the press-body A and head C, the said groove serving the purpose, in whatever position the head is turned, of conducting the heating or cooling fluid to the jacket m fm', which is provided in the press-head C for the circulation of such fluid, which passes from the said groove tothe said jacket through a hole 7e3 (see Fig. 7) provided in said plate within said groove and communicating with the upper compartment m of the jacket m m of the press-head, the two said holes being always kept in register with each other by always shifting the plate F with the press-head C.

The jacket-m m of the press-head is divided into two compartments by a transverse partitition m2, which also extends into the removable bonnet C2 which is provided on said head. The heating or cooling fluid enters through the hole 7c3 into the upper compartment m and passes thence through an opening m4 (see Figs. 2 and 6) inthe partition m2, whence it makes its exit through ahole 7a4, which is shown in Fig.' 7, and which has its position dotted'in Fig. 6, into a second concentric annular groove Z in said plate, which groove is always in communication through a passage 705 in the press-body (shown in section, Fig. 5, and in dotted outline in Fig. 2) with an outlet-pipe k7.

" For driving the screw B the said screw is prolonged in the form of a shaft B and projects through the press-body and through the fixed hub G, before mentioned as bolted to the latter, and a spur-gear J or driving-pulleyis fitted to turn freely on the said hub and connected with the said shaft by a clutch H, which is fast upon the shaft and engages between the spokes of the gear or pulley. The gear or pulley is kept in place on the fixed hub G by means of an annular plate or collar L, of larger diameter than said hub, which g is bolted to the said hub by the same bolts h.

which bolt the said hub to the press-body. This collar L serves as a thrust-bearing for the screw B, the thrust being received from a shoulder n on the screw-shaft IB through steel washers n fn?, inserted into a counterbore in the hub G between the said shoulder and the thrust-collar L. Three washers are represented.

The above-described provision for driving and receiving the thrust of the press-screw relieves the screw of the weight of the gear J or driving-pulley, which is necessarily large and heavy, and it provides facility for changing the screw when necessary, as when the nuts are t-aken olf from the bolts 7L the screw can be withdrawn through the hub G, the thrust-collar coming with it.

In Figs. 1 and 2 there is shown an oil-box p, from which branch passages p are provided leading through the hub G for the lubrication both of the gear or pulley .l and of the thrust-bearing and its washers.

It it should be desired to use the machine to make a simple` cord, the core and coreholder may be removed, and the opening through which the core -holder enters the press-head may be closed by any suitable means.

In the modification of the press-body shown in Figs. 8 and 9' the `circuitous passage between the shell A and the bushing g consists of plain flanges el', cast on the interior of the shell and having each a single opening i3 through it, the said opening being in the upper part of one flange and the lower part of the next one through the series, as may be understood by reference to the said figures. In this'example the inlet is at t* and the exit at i5, as in the first-described example, and the passage 7a2, leading to the head, instead of being cored out, as shown in Fig. 2, fis made by a pipe, as shown in Fig. 9.

The circuitous passage provided in the press-body for the heating or cooling fluid by either of the constructions herein shown and described causes a much more uniform heating of the bore of the cylinder and its contents than a simple jacket formed by two plain cylinders, one Within the other, as has been common in such apparatus.

It may be here remarked that thc plate F IOO IIO

.walls of said recess and pressing on `the'bev` is only made separate from the press-head C as a matter of vconvenience Vfor the construcv tion of the passages in and through it vwhich could not be so=easily made in the'head itself; Abut the said ring, being always shifted With the head C kand never changing its iposition yrelatively thereto, `is to all intents fand purioses a partof thezhead.
