IMPROVEMENTS IN SELF-ACTING STOP VALVES
Year: 1885

page_text: I JOHN CHARLES BAUER of 11 Comerford Road, Brockley in the County of
Kent, Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN SELF-ACTING STOP VALVES to be as follows:-
In carrying out my invention I employ a piece of tube fixed into a cap forming
an annular seating in a backward direction and surrounding the tube. Between
this annular seating and the inner side of the hollow casing enclosing the valve.
I place a ring which is pressed against the annular seating by the action of a
spring resting against the other side of the casing. The casing being provided
with a nozle or other suitable outlet and sliding upon the tube as far as the
spring will admit, it follows that on the valve being pushed back its seating will
open and let the fluid escape, but will close again on such external pressure being
removed.
In order to enable my invention of improvements in Self-acting Stop Valves to
be fully understood I will proceed to describe the same by reference to the
accompanying drawing which represents longitudinal sections of Valves con-
structed according to several modifications of my invention. Similar letters in all
the figures represent similar parts.
In figures I, II, III and IV a is a piece of tube screwed on to or otherwise
connected with the supply pipe; the bore of this tube a is closed at 6 by a cap,
plug or plate soldered on to or otherwise fixed to it. The tube a having one or
more lateral openings as shewn at c and c³, and being closed at b, it follows that
any liquid entering the tube a will, instead of passing straight through, have to
pass through the lateral openings c to the annular seating d which is formed either
by a cap as represented in figure I, by a collar as represented in figure II, by a
plate as represented in figure III, or by the extension of the tube a as shewn.in
figure 1V. The counterpart of the seating consists in either of the above cases of a
ring of India-rubber or other suitable material. The casing e is provided with a
suitable ring or rings f forming an airtight packing between the casing and the

page_text: tube which in figures I, II and IV forms both the inlet and outlet of the valve.
In figure III a nozzle is shewn as forming the outlet. To make the valve
efficiently self-closing I place the spring g in such a manner between the sliding
casing e and the cap, collar or plate fixed upon the tube, that on removing the
pressure necessary in pushing the valve open, the valve will instantly close again.
I JOHN CHARLES BAUER of 11 Comerford Road, Brockley in the County of
Kent, Engineer do hereby declare the nature of my invention for IMPROVEMENTS.
IN SELF-ACTING STOP-VALVES and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:―
In carrying out my invention I employ a piece of tube fixed to a cap forming
an annular seating in a backward direction and surrounding the tube. Between
this annular seating and the inner side of the hollow casing enclosing the valve
I place a ring which is pressed against the annular seating by the action of a
spring resting against the other side of the casing or by the pressure of the fluid
within the valve. The casing being provided with a nozzle or other suitable
outlet, and sliding upon the tube, it follows that on the valve being pushed back,
its seating will open, but will close again on such external pressure being removed.
In order to enable my invention of improvements in self-acting stop valves
to be fully understood I will proceed to describe the same by reference to the
accompanying drawing which represents longitudinal sections of Valves con-
structed according to several modifications of my invention.
Similar letters in all the figures represent similar parts.
In figures I, II, III & IV a is a piece of tube screwed on to or otherwise
connected with the supply pipe; the bore of this tube a is closed at b by a cap,
plug or plate soldered on to or otherwise fixed to it, the tube a having one or more
lateral openings as shewn at c and c¹ and being closed at b it follows that any
liquid entering the tube a will instead of passing straight through, have to pass
through those lateral openings c to the annular seating d which is formed either
by a cap as represented in figure I, by a collar as represented in figure II by
a plate as represented in figure III or by an extension of the tube a as shewn in
figure IV. The counter-part of the seating consists in either of the above cases of
a ring of India-rubber or other suitable material. The casing & is provided with
a suitable ring or rings f forming an airtight packing between the casing and the

page_text: tube which in figures I. II. & IV forms both the inlet and outlet of the valve. In
figure III a nozzle is shown as forming the outlet. To make the valve efficiently
self-closing I place the spring g in such a manner between the sliding casing e and
the cap, collar or plate fixed upon the tube, that on removing the pressure necessary
in pushing the valve open, the valve will instantly close again.
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
1. In the construction of a self-acting stop-valve the employment of a cap, collar
or plate surrounding the lateral openings of the inlet or outlet tube, and forming
an annular seating arround that tube as hereinbefore described.
2. In the construction of a stop valve the employment of an inlet or outlet tube
closed in the bore but having one or more lateral openings through which the
liquid retained by the valve when closed has to pass.
