PROVISIONAL SPECIFICATION.
Improvements in Stop Valves and Regulators for Hydraulic and
other Liquid or Fluid Pressure.
1, JOE WILLIAM LAWRENCE, of 35 Grafton Street, Hull, Oil Mill Engineer
do hereby declare the nature of this invention, to be as follows:-
The object of my invention is to regulate accumulated pressure, and to auto-
matically apply high pressure by means of the low pressure.
a
According to my invention the pressure regulator consists of a body having
round taper or conical hole or chamber within which is a round taper or conical
spindle having a thread thereon engaging into a boss or nut screwing into the said
body. The said round taper or conical hole or chamber joins or communicates with
a pressure chamber in which is a collar or washer of leather or other suitable
material abutting against the said boss or nut.
The pressure inlet may be under the said spindle and then the compressed fluid
passes up through the round taper or conical hole or chamber and past the said
spindle to the pressure outlet (which communicates with the said pressure chamber)
to the working cylinder or other use.
Or the pressure inlet may communicate with the said pressure chamber and pass
down the said round taper or conical hole or chamber round the said spindle and
through the pressure outlet to the working cylinder, or otherwise.
My automatic high pressure stop and regulator consists of a body having a round
taper or conical hole within which is a corresponding spindle. The said round
taper or conical hole communicates with a pressure chamber within which is a
collar or washer of leather or other suitable substance. Above the said collar
or washer is a boss, bush, or nut which screws into the said body, and abutting
upon the said boss, bush or nut is a locknut into which the said spindle screws.
The top end of the said spindle engages into a bush or nut (preferably with wings)
which screws
or threads into a cap or cover screwing on to the said body.
Between the said locknut and the top of the said cover or cap and carried on the
said spindle is a spiral spring.
The low pressure inlet is under the said spindle and the high pressure inlet at
the side of the said spindle.
By screwing or adjusting the cap or cover the pressure may be regulated for the
low pressure, and by screwing or adjusting the winged bush or nut the high pressure
s regulated.

I, JOE WILLIAM LAWRENCE, of 35, Grafton Street, Hull, Oil Mill 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:-
The object of my invention is to regulate accumulated pressure, and to
automatically apply high pressure by means of the low pressure.
Fig. 1, is a section of my pressure regulator.
Fig. 2, is a sectional elevation of my automatic high pressure stop and regulator.
Fig. 3, is an elevation of Fig. 2.
According to my invention the pressure regulator, see Fig. 1, consists of a
body A having a round taper or conical hole or chamber B, within which is a
round taper or conical spindle C, having a thread thereon engaging into a boss or
nut D, screwing into the said body A.
The said round taper or conical hole or chamber B joins or communicates with
a pressure chamber E, in which is a collar or washer F of leather, or other suitable
material, abutting against the said boss or nut D.
The pressure inlet G may be under the said spindle C, and then, the compressed
fluid passes up through the round taper or conical hole or chamber B, and past the
said spindle C to the pressure outlet H (which communicates with the said pressure
chamber E) to the working cylinder or other use.
Or the pressure inlet G may communicate with the said pressure chamber E and
pass down the said round taper or conical hole or chamber, round the said spindle C
and through the pressure outlet to the working cylinder, or otherwise.
In this case H would be the pressure inlet, and G the pressure outlet.
By adjusting the spindle C within the round taper or conical hole B the
passage of the compressed fluid or pressure can be regulated to a nicety.
My automatic high pressure stop and regulator, see Figs. 2, and 3, consists of a
body A having a round taper or conical hole B, within which is a corresponding
spindle C. The said round taper or conical hole B communicates with a pressure
chamber E within which is a collar or washer F of leather, or other suitable
substance. Above the said collar or washer F is a boss, bush, or nut D which
screws into the said body A, and abutting upon the said boss, bush, or nut D, is a
lock-nut D into which the said spindle C screws.
The top end of the said spindle C sliding in a bush or nut C¹ (preferably
with wings C2) which screws or threads into a cap or cover J screwing on the
said body A.
Between the said lock-nut D¹ and the top of the said cover or cap J and carried
on the said spindle C is a spiral spring K.
The low pressure inlet G is under the said spindle C and the high pressure
inlet at the side of the said spindle C.
By screwing or adjusting the cap or cover J the pressure may be regulated for
the low pressure, and by screwing or adjusting the winged bush or nut C¹ so as to
shorten or lengthen the distance between the winged bush or nut C¹ and the
shoulder of the spindle C the high pressure is regulated.

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 would have it understood
that I do not limit myself to the precise details shown and described, but I declare
that what I claim is :-
1. In automatic stops and regulators for hydraulic and other liquid or fluid
pressure, the application of the lower pressure actuating upon a given body, so
causing the said body to admit automatically the high pressure, substantially as
shown and described.
2. In stops and regulators, for hydraulic and other liquid or fluid pressure, the
combination with a body A having a round taper or conical hole or chamber B,
a pressure chamber E (with washer F) joining the said hole or chamber B, and
pressure inlet G and outlet H, of a round taper or conical spindle C having a
thread thereon engaging into a boss or nut D screwing into the said body A, such
as and for the purposes shown and described.
3. In stops and regulators, for hydraulic and other liquid or fluid pressure, the
combination with a body A having a round taper or conical hole or chamber B, a
pressure chamber E (with washer F) joining the said hole or chamber B, and
pressure inlet G and outlet H, of a round taper or conical spindle C connected with
lock-nut D' and boss or nut D which screws into the body A. The said spindle
also engaging with a bush or nut C¹ which screws into a cap or cover J screwing
on the said body A, and a spiral spring K upon the said spindle, such as and for
the purposes shown and described.
