IMPROVEMENT IN THE MANUFACTURE OF FLEXIBLE TUBING.

Specification forming part of Letters Patent No. 5 [,052, dated November 21, 1865.

1'0 all whom it may concern:

Be it known that we, DAVID K. HOXSIE and THoMAs L. REED, both of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful 1mprovements in Flexible Tubing or Hose, such as is used for conveying illuminating-gas and we do hereby declare the following is a full, clear, and exact description of the same, reference being hadto the accompanying drawing, making part of this specification.

In Letters Patent No. 44,425, and hearing date September 27, A. D. 1864, a description is given of a mode of utilizing and converting animal intestines into an impervious sheath or covering for use in the manufacture of tubing or hose.

The improvement in this case is additional to that described and .claimed in the Letters Patent mentioned, and relates to the employment of certain means for preserving the intestinal sheath from splitting or cracking, and thereby becoming leaky, from the usage to which it is necessarily subjected.

' Our invention in this case consists in preserving the intestinein its naturally moist condition after it has entered into the composition of the tubing or hose by the application thereto of a composition of glycerine and glue, or any other material 'or compound that will resist evaporation and stiffening from extremes of heat and cold.

Our invention further consists in the use of a composition of glycerine and glue in proper proportions for rendering the braided sheath or covering which forms part of such tubing or hose impervious, flexible, and smooth on its surface.

Our invention iurther consists in combining upon a suitable spiral-wire coil. forming a skeleton-tube a number of braided sheaths of cotton or other fibrous material and a number (one or more) of intestinal sheaves, in the order of arrangement, and treated and applied and finished to form a flexible tube or hose, as hereinafter described-that is to say:

The said drawing represents a piece of flexible tubing which is composed of a spiral-wire coil, A, which gives form to the tube and prevents it from collapsing by bending it. Over this coil is a covering or sheath, B, of braided cotton, which is saturated or stuffed and coated with enamel-varnish C, (so called) to render shown and described, two or more being' drawn one over the other to provide for any damage from the puncture or otherwise which the lntestines may sustain by the process of cleaning or otherwise.

The natural condition of the intestines durin g existence of the animal is moist and supple; but after being removed from the animal and treated with the chemical solution which is relied on to cure and preserve the strength and utility of the membrane, and'disposed upon the. tubing in the manner intended, the intestinesbecome dry and husky, and areliable after a'ti me to split and crack with being frequently bent and twisted in the way the tubing is used, and after a time the gas will penetrate and escape through the cracks or openings thus formed; and to obviate and efl'ectually prevent this casualty is the object of the present invention, which will now be described.

The animal-intestines maybe prevented from cracking and splitting by being preserved in a permanently moist and supple condition by means of a solution of glycerine and glue in equal parts, the glue being first soaked and dissolved in the usual way by boiling and afterward adding the requisite quantity of glyc erine. This compound is applied while it is warm to the intestines with a cloth or brush and rubbed lengthwise on the tubing vigor ously with the hand. When this compound is intended for use on the braided covering to render it smooth and impervious, the relative proportions should be about two-fifths glycerine to three-fifths (a) glue 5 or the latter may be in still greater excess, according to the consistency required by the nature of the fabric.

The enamel-varnish above mentioned as forming a smooth coating or surface for the re ception of the intestines may be made as fol lows: linseed-oil, twenty (20) gallons; Prussian blue, six (6) pounds. Boil together until the compound is of suitable consistency-say that of molasseswhen withdraw it from the fire, and when it isnearly cool, it being allowed to cool gradually, add and stir in thoroughly about two-thirds the quantity of naphtha. Great care should be taken in adding the naphtha that the vessel is suiiiciently removed from the vicinity of the fire, and as well that the boiled compound has so i'ar cooled as not to ignite the naphtha, frequent and terrible accidents resulting from these causes when care is not observed.

A superior article of impervious flexible tubing may be manufactured from the foregoing materials combined and prepared as follows, namely: first, a lengthened coil of tiuned-iron wire; second, a covering of cotton braid thereon third, a stutfing and coating of enamel-varnish, allowed to dry thoroughly in the open air,

if possible,-otherwise in an oven; fourth,a coating of glycerine and glue, equal parts of each,

, allowed to set or dry, after which asecond coating may be applied; fifth, three intestines, drawn one over the other; sixth, a coating of g] yeerine and glue, equal parts of each; seventh, three intestines, one over the other; eighth, a coating of glycerine and glue, equal parts of each; ninth, a covering of cotton braid tenth, a coating of glycerine and glue, two-fifths glycerine to three-fifths glue; eleventh, a coatingof glycerine and glue, one-fifth glycerine to'four-fifths glue; twelfth, a coating of shellac varnish, (or this may beomitterh) thirteenth,

'a covering of coloredvvorsted, silk, or cotton braiding for outside finish,or cotton stufl'ed with oil (linseed) and varnished.

Instead of the enamel-varnish,.'a coating oi glycerine and glue,.the latter being in excess, may be employed on the braid2to form a smooth and even surfacefor the intestinal sheath.

The use of the processes and materials herein described is also contemplated for preserv ing and utilizing other animal-tissues of a similar nature to intestines, the bladder, 850., for kindred useful purposes, and the same is herein also claimed. 1

Having described our invention, what We claim, and desire to secure by Letters Patent,

1. Preserving animal-intestines and like animal tissues in their natural moist condition by means of a compound of glycerine and glue or other material or compound that will remain unaffected by extremes of temperature, as described. I

2. The use of a compound of 'glycerine and glue in the requisite proportions, in combination with a covering of fibrous material, as and for the purpose described.

3. The tubing constructed wholly or in part of the materials combined in the manner for the several purposes herein set forth and described.

4. The enamel-varnish compound, substan-
