A Flexible Tube Valve or Tap.
I, THOMAS ALLEN BULLOUGH, Ass. M. Inst. C.E. and Chemical Engineer,
50 Peel House Lane, Farnworth, Widnes, Lanc., do hereby declare the nature of
this invention to be as follows:-
For running off corrosive liquors it is usual to have a rubber tube fixed between
two pipes and to stop the flow of the said liquors the said rubber tube is pressed
down until a seal is made. I now propose to make the tube flat in the centre so
that the pressure of the liquid will open a through-way-an iron screw plate being
used in the ordinary manner to stop the flow of the liquid. The object of the
invention is to reduce the wear and tear of the tubes by constructing them of flat
shape instead of circular shape. The said tube may be constructed of any desired
flexible material suitable for the passage of liquids or gases either at high or low
pressures. The said tube would be suitable for use in the operations of the
"Chances Sulphur Recovery Process."
For high pressures I propose encasing the said flexible tube in an iron casing or
pipe thus forming a novel through-way valve or tap.
Dated this Sixth day of December 1890.

COMPLETE SPECIFICATION.
A Flexible Tube Valve or Tap.
I THOMAS ALLEN BULLOUGH 50 Peel House Lane Farnworth Widnes, in the
County of Lancaster, 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:—
In the process of transmitting or conveying corrosive liquids and gases from one
vessel to another, a tube made of india-rubber and circular in section is generally
used. To stop or check the flow or passage of the said liquids and gases, an iron
screw clip is used which causes the destruction of the said rubber tube at the part upon
which the clip is fixed. My invention is designed to reduce the wear and tear to a
minimum. With this object I construct a tube made of india-rubber, dermatine,
woodite asbestos, or metal, flat in section instead of circular. For low pressures
this design is suitable, but for high pressures I construct a metal covering or shield
in the form of a pipe with suitable flanges and screwed stopper. Another method
could also be adopted for the prevention of the bursting of the flexible tube by
embedding in the body of the tube canvas, wirework, or other suitable strengthening
material. It is obvious that the flexible tube is suitable for other liquids such as
are non-corrosive as water; also for semi liquids holding mud in suspension.
In the accompanying drawing
Fig. 1 is a side elevation of the said flexible tube,
Fig. 2 is a view shewing the thin edge of the flat part of the said tube.
Fig. 3 is an end view, and
Fig. 4 is a cross section of the flat part of the said tube as described in the

page_text: 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. The design and construction of a flexible tube valve or tap, flat or oval in
section, instead of circular in section substantially as described whereby a large
part of the wear and tear is saved.
2. The employment of a tube made flat or oval to act as a valve or tap instead
of the tubes, valves, and taps commonly used, substantially as described.
Dated this 11th day of May 1891.
