A METHOD OF LINING TUBULAR FABRICS FOR THE MANUFACTURE OF HOSE FOR HYDRAULIC OR OTHER PURPOSES
Year: 1884

page_text: I, PETER JENSEN of 33 Chancery Lane in the County of Middlesex Fellow of
the Institute of Patent Agents do hereby declare the nature of said invention for
"A METHOD OF LINING TUBULAR FABRICS FOR THE MANUFACTURE OF HOSE FOR
HYDRAULIC OR OTHER PURPOSES (A Communication to me from abroad by John
Van Dussen Reed of Barclay Street in the City County and State of New York
United States of America Gentleman), and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
This invention will be understood by reference to the accompanying drawings in
which Figure 1 is a side elevation of so much of a knitting machine as is required
to illustrate the invention Figure 2 shows an end view of the fabric tube in the
position in which it is knitted and a rubber tube within it in a position which a
Hattened or collapsed tube such as I prefer to use frequently assumes, or con-
veniently may be made to assume.
Figure 3 is a perspective view of a piece of a flattened or collapsed tube such as
for convenience of making handling and transporting I prefer to use though I do
not intend to confine myself to the use of a tube of this form the invention
consisting of a method of lining tubular fabrics during the process of their manu-
facture which enables me to knit a covering about a lining tube without an
arbitrary expansion of said lining tube for that purpose.
Fabric tubes have been lined prior to the time of this invention either according
to one method by first weaving a fabric tube and by then drawing a rubber tube
through it, which method is troublesome upon hose of small diameter, as for
instance those sizes suitable for garden hose, in consequence of the difficulty of
drawing the tube through a hose of such diameter, or according to another method
by weaving or braiding a fabric tube directly upon the rubber tube, the said rubber
tube being expanded by means of a mandril or some other body or substance
within it, but this method is for obvious reason objectionable.

page_text: For the purpose of my invention I employ any knitting machines either plain or
those employing additional weft and warp threads, that will permit a lining tube
to be inserted within the fabric tube while it is being knitted From a coil of
lining tubing A Figure 1 placed either above the knitting machine as here shown
or at any other convenient point I lead the free end of the tube down and insert it
into the open mouth of the knitted tube at B, and either fasten the lining tube A
to the fabric O or hold it within the fabric tube in some other manner, so that the
rubber tube will be drawn down and carried away by the take-up rolls D with and
within the fabric tube.
The hose so made may be subjected to the usual steaming process after it leaves
the loom, to cause the lining tube to adhere to the fabric tube, and it is upon such
or other secondary process that I rely to cause the size and form of the lining to
conform to that of the fabric (and not upon a mandril or any other body or
substance in the tube during the manufacture in the knitting machine.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that
what I claim as the Invention communicated to me is
First: The method of manufacturing lined knitted hose or tubular fabrics
which consists in leading or feeding a lining tube within the fabric tube during
the process of its manufacture, such lining tube to be inserted in a flattened
collapsed or other shape which such tube is liable to assume (when not subjected
to arbitrary expansion by means of a mandril, or some other body or substance
within the said lining tube) and subsequently subjecting the hose to a secondary
process for causing the lining tube to adhere to the fabric tube substantially as set
forth.
Second-Feeding a collapsed tube into the interior of a tubular fabric during
the process of knitting the fabric tube, for the purpose of forming a lining for the
fabric tube substantially as set forth.
Third Lining a tubular fabric by knitting the fabric about a tubular lining
fed into the interior of the fabric tube during the process of knitting, without
inflation or distention of the lining tube substantially as set forth.
