Improvements in Composite Hose.
I, JOHN COCKBURN, Superintendent, North British Rubber Company, Limited,.
Mechanical Department, Castle Mills, Edinburgh, do hereby declare the nature of
this invention to be as follows:-
This invention has for its object the production of hose having a flexible metallic
lining to protect the body of the hose from the action of steam or of other fluids or
liquids conveyed through it and also the protecting or armouring of the outside of
hose by a continuous metallic surface.
I form the flexible lining for the hose of metallic strips or ribbons of channel'
section coiled in helical form to constitute a continuous length of tubing two or
more ribbons being used the inside one having its bent over edges turned outwards
whilst the adjoining outside one of the coil has its bent over edges turned inwards so
that one coil overlaps and engages the edges of the adjoining coils.
Such a tube may be made fluid tight when subjected to internal pressure by
filling the channels of the metallic ribbons with rubber or other suitable material
but in general this metallic flexible tubing is simply covered with rubber, rubber
cloth or like material as ordinarily used in making rubber hose to serve as a fluid
or steam proof covering to the metallic lining above described.
For the outside protection or armouring of hose similar metallic grooved ribbons
are simply spun on or applied to the outside of the india rubber or other material
forming the body of the hose.

COMPLETE SPECIFICATION.
Improvements in Composite Hose.
I, JOHN COCKBURN, Superintendent, North British Rubber Company, Limited,
Mechanical Department, Castle Mills, Edinburgh, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention has for its object the production of hose having a flexible metallic
lining to protect the body of the hose from the action of steam or of other fluids or
liquids conveyed through it and also the protecting or armouring of the outside of
hose by a continuous metallic surface.
As illustrated by the accompanying drawings Figure 1 of which is a transverse
and Figure 2 a longitudinal section, I form the flexible lining for the hose A of
metallic strips or ribbons B, B¹, of channel section coiled in helical form to
constitute a continuous length of tubing, two or more ribbons being used the inside
one B having its bent over edges turned outwards whilst the adjoining outside
one B' of the coil has its bent over edges turned inwards so that one coil overlaps
and engages the edges of the adjoining coils.
Such a tube A may be made fluid tight when subjected to internal pressure by
filling the channels of the metallic ribbons B, B', with rubber or other suitable
material as shewn but in general this metallic flexible tubing is simply covered with

page_text: rubber C, rubber cloth or like material as ordinarily used in making rubber
hose to serve
as a fluid or steam proof covering to the metallic lining above
described.
_For the outside protection or armouring-of-hose--similar- metallic grooved
ribbons D, D¹, are simply spun on or applied to the outside of the india-rubber C
or other material forming the body of the hose A.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. Composite hose formed with a flexible metallic lining, substantially as
described.
2. Composite hose formed with flexible protective armouring, substantially as
described.
3. Composite hose formed with flexible metallic lining and protective armouring,
substantially as described.
Dated this 17th day of October 1894.
