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

SPECIFICATION forming part of Letters Patent No. 466,910, dated January 12, 1892. Application tiled August l, 1891. Serial No.` 401,387. (No model.)

To all whom t may concern:

Be it known that we, VERNON ROYLE and JOHN ROYLE, J r., both of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Machines for Covering XVire, Cables, dro., and for Making Tubing and Cord, of which the following is a specification.

Our invention relates to an improvement in machines for covering wire, cables, dre., and for making tubing and cord, in which the material in a soft or plastic state is forced around a core through a die.

lOne object is to prevent, in covering wire or cables, the contact of the bore of the hollow rotating screw through which the wire or cable passes with the surface of the wire or cable itself; and to this end the invention consists, principally, in a stationary tube arranged Within the said screw to conduct the wire or cable through it. y

Other objects are to utilize the pressure of the material being forced to close the joints between the core-bridge and pressurescrew and end of conducting-tube within the pressure-screw, to provide for maintaining the end of the conducting-tube in contact with the core-bridge when the machine is not in operation, and to provide for obtaining and maintaining the relative adjustments of the core and the die.

A practical embodiment of our invention is represented in the accompanying drawings, in which- Figure 1 shows a longitudinal4 section through the pressure screw, the trunk in which the pressure-screw operates, the presshead, and parts in proximity thereto; and Fig. 2 shows a central section of the die and core on a larger scale than Fig. l.

Similar letters and numerals of reference designate corresponding parts in both figures.

Such portions of the su pporting-frame, driv-` ing mechanism, the., which are not essential to a clear understanding of our present invention have been omitted and may be of any well-known or suitable structuresuch, for example, as shown and described in Letters Patent No. 325,363, granted to us September l, 1885.

A represents an abutment forming a part of or fixed to the supporting-frame of the machine and provided with a bore therethrough, one end of which a is intended to receive the stem b of the thrust-piece B, and the opposite end a of which is screwthreaded to receive the tail-screw C for forcing the thrust-piece to its work.

D represents the trunk, within which the hollow pressure-screw E is located, the rear end of said screw abutting against the face of the thrust-piece B and provided with the drive-wheel F.

The press-head is denoted by G, and is xed to the end of the trunk D and provided with an opening therethrough, forming a contracted prolongation of the opening within the trunk in which the pressure-screwE is located. Within the outer end of the opening through the press-head, the die H is 1ocated, and the core-bridge I, carrying the core t, is seated between the press-head and the end of the trunk D within a space formed therefor around the inner margin of the open ing in the press-head. From the inner face of the core-bridge I, where the core t' is fixed thereto, a stationary conducting-tube K extends longitudinally through the pressurescrew, the thrust-piece B, and the tail-screw C and is intended to conduct the article to be covered therethrough into and through the hollow core@l and through the opening 7L in the die Il in alignment therewith, and also to protect the said article from contact with the rotating surface of the interior of the pressure-screw. It is found to be of importance to keep the joint between the core-bridge and the end of the tube K tightly closed against any liability of certain materials which are being forced through the die by the pressurescrew fromenteriug therein. We accomplish the desired closure of this joint when themachine is in operation as follows: The end of the tube K in proximity to the core-bridge I is provided with a nut 7.a, screwed thereon, the face of which is iitted to the inner face of the core-bridge, and theback of which is preferably inclined or beveled, as shown at 7c. The pressurescrew E terminates a short distance back from the nut 7n, and is provided at its end with a bearing L, preferably formed separate from the pressure-screw and inserted snugly in its end, forming a close fit around the tube K. The face of the bearing L toward IOO the nut k is also preferably inclined or beveled, as shown at Z, in a direction opposite that in'which the nut his beveled, so as to form between the two faces an annular space which gradually contracts toward the axis of the tube K. From this it follows that when the material is being forced through the corebridge into the die by the pressure-screw E this pressure will be exerted between the nut k and the end of the pressure-screw, and will thereby tend to force the nut and end of the tube K into close contact with the core-bridge, the pressure to close the joint being increased as the pressure to force the material through Jthe die is increased. We further find it desirable to insert apacking-ring m of someksuitable material-asbestus, for examplebetwee'n the nut 7i; and the bearing L'in close contact with the exterior of the tube K, tov

prevent the creeping of the plastic or other materialbeing operated uponbetween thebearin g L and the tube K. The tube K is provided near its outer end with'an abutment a2, here shownasaring-nutscrewedthereon,andiskept stat'ionary-that is to say, prevented vfrom' turning with the pressure-screw E by means of a screw m tapped through the side of the tail-screw@ and projecting into a groove 7c3 in the periphery of the nut. A spring N is inserted against the face of the abutment a2 andthe inner end ofy a thrust-screw O,`the latterv being screwed into the end of the tailscrewC. vBy turning the screw O to forceit inwardly the spring N is forcedinto contact with the abutment a2, and the tube K thereby held yieldingly incontact with the inner vface of the core-bridge I; This insures a cont-act between the nut k and the endof the tnbeK with the'core-bridge when the machine is not in operation,`and atv the same time admits of u in Figp'l the die 7L, which is screwed into the the p resshead,is of one piece; but in the exani'pleshown in Fig. 2 itis fitted tightly into a` collar hi, which is screwed into the presshead. The bore'or operative part of the die is the same in both cases, the front portion 3 ofthe bore being cylindrical and of proper caliber for theexterior of the covering and the portion 4 in rear being counterbored somewhat 'larger and of substantially cylindrical form.l The exterior of the core c', which is tapered, enters into this cylindrical counterbore and not into the bore proper 3.1 The space between the taper core and the cylindrical conn`terbore4 is narrower at its entrance 5 It is provided with a jam-nut than it is further forward, and we have found by repeated experiments with dies of different form that this contraction at 5 and the gradual widening farther forward, resulting from the cylindrical form of the counterbore, better insures .the maintenance of the concentric relation between the die and core. It is obvious that the counterbore 4 need not be absolutely cylindrical and that it might be of a slight taper less than the taper of the core and yet preserve this feature of contracting the annular space between the die and core at the point 5 as compared with the width of thesaid space further forward. The said contraction may be varied and adjusted by the screwing of the die more or less into or out from the head'G. m

Such features as we have shown andnot particularly described are'quite vsimilarjin their structure and Voperation to the correspondingfeatnres shown and described .in our.

Letters Patent herein'beforev referred to, and particular reference thereto has been purposely omittedy herein, except so Vfar as they relate to vour present improvements.v

' NVh'at4 we claimv 4as our invention, and desire' to secure byy Letters Patent, isf-'- L 1. The combination, with the trunk and the hollow pressure-screw, of' Va stationary tube within the said pressure-screwy and 'supports 'for said tube latthe ends thereof, substantially asiherein described.

`2. The combination of the externally-tapered core and the' die'counterbored substantially cylindrical" to4 produce acontractionxof -the annular space between the'core anddie at, a point some distance in 'rearzof the'lfront of said space, and thegradualv widening ofsaid Vspace infront `0f said contraction, substantially as and for the purpose herein setfozrth.Y

3. The combination, substantially as herein 1 set forth, of the press-head, the core-bridge, :and the external taper core, of the die counterloored substantially cylindrical to produceV a contraction of the annular space between the core and die, as herein described, andadjustable in the press-head relatively to the core to vary the saidcontraction.

4'. The combination, With a core-bridge, the pressure-screw, and the conducting-tube within the pressure-screw, of a laterally-extended bearing on the endof the tube, adaptedto engage the core-bridge, and a space betweentlie back of said bearing and the end of the pressure-screw for receiving the material'being forced, substantially as set forth.

5. The combination, with the core-bridge, the pressure-screw, and the conducting-tube within the screw, of a laterally-extended bearing on the end of the tube'in proximity to the core-bridge, and a bearing at the endlof *the pressure-screw, the adjacent faces of said bear- V ings being beveled, forminga spacegradually contracting toward the axis of ,thc tube, substantially as set forth. 6.
