i `IBe itknown that I, JAMES REYNoLDaof thecity, "county, andi State `ofcNew York, have invented `new and usefulfflmprovef `ments on thevMachineryfo-r Apparatus for Making Hose or Tubesof any Plastic Mate` rial and for Insulating Telegraphic er other Wires; and II dohereby declare that the fol-` lowing is a full,":clea`r, and exactfdescription ofzthe same, reference being had to the` accompanying drawings, forming part of this speciiicatiomiin{which4- u i i i Figure 1, is la front elevation.

band or strip of the plastic substance, which` is fed into the stomachtof themachine by friction rollers, and delivered through a suitable mold tube, that, together with its,

mandrel, or wire guide, are situated at right angles, or other similar position, with relaf tion to the feed rollers. y

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, A, A, A, is the frame of the machine, with cheeks or projections, B, B, in Which work feed rollers C, C, having pinions D, D, andv driven by handle E, worked by hand, steam, or other power `in any suitable way: the rollers C, C, may be notched, grooved, or smooth, according to the substance they feed or operate on, and are set at a proper distance apart, so as to bite on the material being fed. n y

F, F, is a stomach or internal vessel having a cavity orinterior space g, g., and lip or mouth It, (Fig. 2), which projects out-` ward, being of the same breadth as the rollbutting up `againstlthe rollers C, C.

at `its interiorend, of less diameter ,"than,

but corresponding to, and partly entering,

the `conical space or mouth ofthexpassagea, `of the tube J g and is constructed with a circular passage t `(Fig.` 3), of suitableishape,

the center of which, istin the same `line as the n YW, `(F'g. -`4,).is a tube'mold, similar `to the mold i J, `and fitting in the esame: cavities through the outer case F, F, and stomach G, G; and N, (Fig. 4) is a mandrel, orcore,` being similar to the wire guide L, having a passage lengthwise through it for supplying the tube with air to prevent collapse, and its inner end probelng a modification of the guide L, and i u the tube mold M, being the same as the i mold J, and operating in'a similar manner.

The operation is as follows. The substance of which the tube is to be made (and which may be gutta percha, orfany other u plastic material) being previously cut, or

rolled, in the shape of a band, is held or forcediup to the feed rollers C, C, which by turning the handle E, and through pinions D, D, are put in motion, biting and drawing in between them, the plastic substance, which enters the mouth h, (as seen in Fig. 2,) and so passes on to the space g, g, of the stomach Gr, Gr, where it is melted or made soft or iiuid (as seen in Fig. 3,), through the steam or heated medium in the interior of the outer case F, F, and surrounding the stomach Gr, Gr, which it heats. When the space g, g, is full of the plastic material, reduced, by the application of heat as described, from its form as a band, to a fluid or softened mass, the band being still drawn in` by the rollers C, C, causes, a pressure to be thrown upon, and multiplied over the mass in the space g, g, which is thus rendered firm, and lforced out through the passage in the tube mold J; and if the wire guide L, be used and wire, simultaneously, be fed through L, (as seen in Fig. 3,) the plastic material entering around the conical point of the guide L, will surround and cover the Wire, and be delivered at the eX- ternal extremity of the mold J, asv an insulating tube containing the wire, and as represented by Fig. 5; or if the mandrel for core N, and tube mold M, be used, the plastic substance will be forced out in the same Way, entering the passage of the tube mold M, and lapping over the Prolongated part of the mandrel N, which projects up the passage of the tube mold M, and forms the caliber or. internal diameter of the tube or hose, its thickness or strength being proportioned according to the relative diameters of the passage through the mold M, and

the prolongated part of the mandrel N, situated conoentrically within it; the material forming the hose being cooled before leaving the mold M, and being deliverd in form of a tube or hose similar to that represented by Fig. 6.

As the tube or hose is thus formed, and delivered, at right angles with the line in which the material is fed to the machine, the grain or fiber of the band, lying in direction of its length, (or so produced by the macerating process to which it may be subjected), a twist is formed in the production of the tube or hose, Which imparts greater strength and renders it less liable to split or open, than when the tube is formed of fibers lying in direction of its length. Also bythe arrangement of the stomach as shown and described, its lip h, projecting outward up to the rollers C, C, air is excluded from entering the space g, g, alonO' with the band, thus avoiding air cells,

and tby the pressure produced in the mode.

of feeding, forming a sound and strong hose or tube. Likewise the arrangement of feeding, by rollers C, C, and using bands of plastic material enables, the supply to the feed being regulated, according to the required length of tube, and at any suitable speed, according to the heat operating in reducing the material to a soft, or fluid, state; thus showing many, and great, advantages over the ordinary arrangements.

l/Vhat I claim as my invention and desire to secure by Letters Patent is- The use, for the purposes specified, of feed rollers C, C, in combination with va stomach Gr, G, having a lip or mouth L, arranged and operating, substantially as shown and described.

In testimony whereof I have hereunto signed my name before two subscribing witnesses this 20th day of December 1850.

JAMES REYNOLDS.
