I, FRANK REDDAWAY, Managing Director of the Firm of F. Reddaway & Co.,
Limited, of Cheltenham Street, Pendleton, in the County of Lancaster, Woven
Hose and Machine Belting Manufacturers, do hereby declare the nature of this
invention to be as follows:-
-
My invention relates to improvements in and in the manufacture of tubing or
hose and has for its object to produce hose which shall be particularly suitable for
conveying hydro carbon oil gas and the like.
As at present manufactured the hose used for this purpose consists of an inner
or central tube or core of rubber wrapped round with a number of plies of canvas
around which a strengthening and protecting serving of wire is coiled, on the well
known Sphincter grip principle.
Owing to the destructive action of hydro carbon oil gas on rubber, hose so
constructed is apt to rapidly deteriorate and to lose its efficiency owing to the
hydro carbon oils at once attacking and destroying the rubber whereby the gas
tight qualities of the hose are impaired.
Under these circumstances the life of such hose is comparatively short.
In manufacturing hose according to my invention I first prepare a metallic core
or lining preferably from coiled steel wire. The coiling is effected in the ordinary
or in a suitable manner. This coiled wire constitutes the foundation of the hose
and around this foundation I wrap two, three or any suitable number of plies of
canvas duck which has been previously coated with rubber solution so that the
plies adhere together. When the hose has reached this stage I slip or draw over
the canvas a tube of india rubber, or I might enclose the canvas in strips of rubber.
Upon the rubber jacket I now wrap four or it might be more than four plies of
canvas according to the desired strength of the hose.
The hose is finally protected by one or more coils of wire in accordance with the
well known Sphincter grip principle.
Hose thus constructed is extremely durable owing to the fact that the rubber is
shut off by the canvas layers from contact with the hydro carbon oil gas so that the
impermeable nature of the complete hose is preserved for a longer period. The
central coiled wire core also prevents collapse of the hose, under trying circum-
stances.

I, FRANK REDDAWAY, Managing Director of the Firm of F. Reddaway & Co.,
Limited, of Cheltenham Street, Pendleton, in the County of Lancaster, Woven

invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying
drawings:-
My invention relates to improvements in and in the manufacture of tubing or
hose and has for its object to produce hose which shall be particularly suitable for
conveying hydro carbon oil gas and the like.
As at present manufactured the hose used for this purpose consists of an inner
or central tube or core of rubber wrapped round with a number of plies of canvas
around which a strengthening and protecting serving of wire is coiled on the well
known Sphincter grip principle.
Owing to the destructive action of hydro carbon oil gas on rubber, hose to
constructed is apt to rapidly deteriorate and to lose its efficiency owing to the
hydro carbon oils at once attacking and destroying the rubber whereby the gas
tight qualities of the hose are impaired.
Under these circumstances the life of such hose is comparatively short.
My invention will be clearly understood from the following description when
read in conjunction with the annexed sheet of drawings..
In the said drawings,
Fig. 1 shows a short length of tubing or hose, the view being designed to show
more plainly the constituent parts.
Fig. 2 is a cross section of the hose.
In manufacturing hose according to my invention I first prepare a metallic core
or lining of wire, preferably from coiled steel wire. The coiling is effected in the
ordinary or in a suitable manner. This coiled wire a forms the foundation of the
hose and around this foundation I wrap two, three or any suitable number of
plies 6 of canvas duck or the like which has been previously coated with rubber
solution so that the plies adhere together. In the drawing three plies of such
canvas duck are shown encircling the wire core a.
When the hose has reached this stage I slip or draw over the canvas, a tube c of
india rubber, or I might enclose the canvas in strips of rubber arranged spirally
or otherwise around the inner fibrous serving b. Upon the rubber jacket c I now
wrap three, or it might be more or less than three, plies d of canvas or the like
according to the desired strength of the hose.
The hose is finally protected by one or more coils e of wire in accordance with the
well known Sphincter grip principle.
Hose thus constructed is extremely durable owing to the fact that the rubber is
shut off by the canvas layers from contact with the hydro carbon oil gas so that the
impermeable nature of the complete hose is preserved for a longer period. The
central coiled wire core also prevents collapse of the hose, under trying circum-
stances.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
The improved tubing or hose, for conveying hydro-carbon oil gas and the like,
