PROVISIONAL SPECIFICATION.
Improvements connected with Armoured Flexible Hose.
I, JOSEPH THOMPSON, of The Sphincter Hose and Engineering Company
Limited, 9 Moorfields, London, Engineer, do hereby declare the nature of this
invention to be as follows:-
:-
All armoured hoses when under pressure expand endways, thus putting undue
strain upon the canvas plies and rubber, frequently causing the hoses to burst.
This invention consists in locking the wire armour in such hoses with longi-
tudinal wires or metal strips, in such manner that all longitudinal strain is taken by
these longitudinal wires, thus relieving the hose itself of all end strain.
In carrying out this invention, I fix a metal strip or strips beneath the wire
armour, these metal strips are so formed with corrugations to correspond to the
pitch of the armour, so that when the hose is armoured the armour lies in these
corrugations; or I use one, or more wires radially around the hose under the wire
armour in a longitudinal direction, and as the wire armour is laid upon the hose,
each of these longitudinal wires are made to take a turn round the same, thus
securely locking each coil of the wire armour to one another from end to end of
the hose at any required distance apart, thus these longitudinal or locking wires
take all longitudinal strain when hose is under pressure, and so relieving hose of
all end strain as heretofore.

Improvements connected with Armoured Flexible Hose.
I, JOSEPH THOMPSON, of The Sphincter Hose and Engineering Company,
Limited, 9 Moorfields, London, Engineer, 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 :-
All armoured hoses when under pressure expand end ways, thus putting undue
strain upon the canvas plies and rubber frequently causing the hoses to burst.
This invention consists in locking the wire armour in such hoses with longi-
tudinal wires or metal strips in such manner that all longitudinal strain is taken by
these longitudinal wires, thus relieving the hose itself of all end strain.
In carrying out this invention as shown in the annexed drawings in which
Figures 1 and 2 are section and plan respectively of a hose, the armour of which
is locked by a flat, or it may be a round corrugated wire, and Figures 3 and 4 are
a similar section and plan in which the armour is wrapped by other wires of any
desired section, I fix a metal strip or strips A, A, Figures 1 and 2, beneath the
wire armour B, these metal strips A are formed with corrugations C to correspond to
the pitch of the armour B, so that when the hose D is armoured, the armour B
lies in these corrugations C by which it is securely locked in position upon the
hose and effectually prevents any expansion, or I use one or more wires A, A,
radially around the hose D under the wire armour in a longitudinal direction and
as the wire armour B is laid upon the hose D, each of these longitudinal
17

page_text: wires A, A, are made to take a turn round the same in the manner shown in
Figures 3 and 4, thus securely locking each coil of the wire armour to one another
from end to end of the hose at any required distance apart. Thus these longi-
tudinal or locking wires A, A, whether as in Figures 1 and 2, or 3 and 4 take all
longitudinal strain when the hose D is under pressure, and so relieving it of all
end strain as heretofore.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The improvements hereinbefore described and connected with armour flexible
hose as set forth and represented.
2. Combining longitudinal strips of metal or wires having kinks or depressions
into which the spirally arranged armour wrapping engages or finds a lodgment on
flexible hose, as described and substantially as shown.
3. Curling wire on the armour wrapping of flexible hose said curled on wire
being arranged radially around and in touch with the hose between the spiral
wrapping as and for the purposes set forth, and substantially as shown at
Figures 3 and 4 of the annexed drawings.
