To all whom it may concern:
Be it known that I, JonN H. Cnanvna, of the'city, county, and State of New York, have invented a new Improvement in Yulcanizing Rubber Hose, of which the following is a specification. I c
The object of this invention is to vulcanize flciently, andquiekly than heretofore without liability to overvulcanizingthat is, decomposing or burning-the same, and to produce a perfect hose, both in external appearance be equally vulcanized throughout it shall also have a smooth and perfectly cylindrical external coating and internallining, and thereibreafi'ord a more perfect and merohautable' commodity than has hitherto beenknown Of the vulcaniziug or curing processes heretofore in use, aswell as of the methods of making or forming the hose, it is unnecessary here to give any special des'cription,they being familiar to those acquainted with the manufacture of vulcanized-rubber goods.
Rubber base, as is well known,is composed,
in part, of canvas or cloth, threads warps, yarn, or other llbrous'or textile material, and in part ofind'ia-ru-bber or other vulcanized gum,
which latter act'sas a cementboth for uniting.
the several folds of canvas or threads'to' form them into a cylindrical body, and for rendering the hose impermeable to-water, steam, or
other'fluid. v I I The present invention. concerns ouly the Vulcan-lain g or curing operationfln accomplishing which he processes and methods known and usedprior ficient. Hosevulcanizedin accordance with such methods .is liable to'beimperfectl'yvulcanized; or if thorough vulcanization is sought period of time than is generally deemed neeesplied, and the vulcanization be thoroughly and lE. k' fi k The maintaining of thepressure'ot' the stealn June 3', 1868, numbered 79,220
to this invention are very de-' to be obtained, and if, therefore, they' are allowed to remain in-the-heater for a longerdecomposing orburning-the rubber, 5
labor and the uncertainty of obtain- 5 My said invention rnaybe stated, in genera terms, to consist iu vulcaniziug or heating the that the heat for vulcauizing the article from the exterior can be readily'and effectively a por expanding agent within the tube or envelope during the vulcauizing operation, or until vulcanization-shall have been accomplished,
also forms a part of the invention.;.=
To enable others to make and use my said,
invention, and to understaudthejmanner in" which the same is or may be carried "into effect,
-1 shall now proceed to describe several modes employed by 'md to vulcauize boss ofvarious kinds.
First. T0 line seamless or woven hose .1 introduce into the interior of the hose, in .any' known manner, a liniugvof. india 'rubber or- -other vnlcauizahle gum or compound in the green state,
I or partly vulcanizable and partly nou-vuloaniz'able, as described in Letters-Pat'- ent grantedto-JameQ. Forsyth and myself with its lining, I then place in a metallic tube orcylindri'cal envelopeof such internal dififty feet long-audshouldbe connected at 01 end with aste'ampipeand provided at- This hose,
"am'eter' that the hose will flt it snugly, which I the other with a blow-cit pipe ha'vingastopcock. 'After -the' tube is run into the heater steam should-be leg on, which will. enter the interior of the hoseaud force the vulcanizable lining against the interior surface of the fahrjv, thus causingsthe union of the tivoantl thevnlcau'iz 'tion of the-lining. The stemn-pressure a gerfect article are,however, the princi- 5 pa di culties attending thlsmanufacture; also the the hose against .100
, the surrounding metallic tube or envelope,
thus giving a very complete flllISI] to the exterior of the hose, and preventing it from bulging in spots or expanding unequally and from becoming crooked-defects which are frequently found in hose-of this kind made without the employment of an external metallic e1 |velope. The steambeing kept on durin gthe operation maintains the propel-degree of pressure within the'nose. Fresh steam is thus supplied to take the place of any condensed or escaped steam.
When the vulcanization is complete steam is shut 011',- and what remains in the hose, Whether still in the form of steam or condensed into water, can escape at the other end through the cock, which is opened for the purpose. In lieu of steam it will be of course understood that hot air or other suitableexpanding agent may be employed.
In order to make seamless hose both coated and lined with vulcanized rubber I take the fabric base of the hose and apply to its exterior and interior a coating and a lining of properly-prepared rubber in the green state by any of the known methods. I then place the hose thus prepared in the metallic tube, which is run into the heater until the vulcanizing'operation is completed, steam or other expanding agent being introduced into the interior of the hose, and there allowed to remain until the close of the operation, in order to force the lining out into close. contact with the interior walls of the hose.
Second. The same process is applicable to the manufacture of hose made up in the usual manner-that is, by wrappingiargund a. man drelrubber in the green state being interposed between its folds. Hose of thiskind can be lined, or both lined and coated, with a sheet 'ol'green rubber or other vulcanizable substance in the ordinary way. It is then introduced into the metallic tube or envelope, the latter is placed in the heater, and the steam let on, as before. The heater he ts the tube and iucloscil hose from the outside, and the steam.
acts on the hose from the inside, so thatin' this manner a periectlymolded and vu h-l-unized hose with ahighly-linishcd exterior, and either lined or both lined and coated with rubber, is produced.
Third. The sameprocess is also applicable to the manufactureof hose made by threads, warps, yarns, or fabric wound spirally on a mandrel; and, indeed, my method is here highly necessary, as it wouldbe dangerous and productive of injury to hose of this kind to introduce into it steam at any considerable pressurevunless the hose were contained in the external metallic tube or envelope.
From the above the manner in which my process may be applied to the manul'acture of other kinds of hose will be-obvious to those skilled in the art to which this invention relates.
'lliclhcat to vulcanize the hose from the exheater of ordinary or suitable construction,
but for this'purposc the metallic tube, envelope, or 'mold' may be provided with a jacket for the,rcception of. steam or other heating agent, and that with considerable advantage. With a jacket the required temperature can be obtained with greater promptness and certainty, so that the vulcanization is effected in less-time. The several operations are'performed in tlie'mauner already stated.
The metallic tube or envelope may-be of an y suitable length and dimensions. about fifty feet is well adapted for the use for which it is designed. It should be well finished internally, so as t/u impart the proper finish to the exterior of "the hose, and if made in sections they should be snuglyand accurately fitted together, so as not to form any seam or ridge onthe surface of the hose. If, however, a. scam in any instance shouldbc forlnedfit may be cut oti' by running a propcrly-gaged'knife along the surface of the hose.
Thetube may also be divided longitudinally into two halves hinged together, so as to open and close to permit the easy introduction and withdrawal of the hose. In short, its form A length of and construction may be varied in many ways" which I do not deem it necessary to further particularize, it being manifest that theim poi-taut point is, that it be made of metal or other suitable material with sutlicicnt strength and resistant capacity to support the inclosed hose against the pressure of the steam within it during the ulcanizing operation, or while the steam is let on, thereby preventing the hose from becoming misshapen, and imparting a very perfect linish to its exterior.
Therefore.
What Iclaim as'my invention, and desire to secure by Letters Patent, is-
1. The employment, in the process of vul- I canizing hose, of stean'i or other expanding agent introduced within the hose, in conju-nctionlwith an external metallic tube or envelope, which incloses thc ho'se and retains therein the steam 'or other expanding agent during the 'nlcanizing operation. substantially as set forth.
The process of vulcanization by the-use of jacketed envelopes or molds, in combinationwith means, substantially as described,
for producing internal pressure.
;3. In the 'process of vulcanization by the in conjunction with an external metallic envelope, maintaining the pressureot'. said agent iio 12o employment of an internal expanding agent,
