AN IMPROVED AUTOMATIC SELF-CLOSING VALVE OR TAP
Year: 1885

page_text: SAMUEL ALBERT JOHNSON of 24 Glengall Road, in the parish of Poplar and
County of Middlesex, Marine Engineer, do hereby declare the nature of my
invention for "AN IMPROVED AUTOMATIC SELF-CLOSING VALVE OR TAP," to be as
follows:-
The object of this Invention is to freely permit of water, gas or other liquid or
fluid under pressure passing and being regulated at will, and to arrange for the
Valve or Tap being instantly closed on the handle being released, and securely
checking any waste or escape; this I effect in the following manner:
I take or form a casting, somewhat similar to the ordinary Cock, Tap or Valve
in use, of suitable shape, open at one end to admit of the passage of water or other
fluid or gas, but having a bar or guide cast therein with an opening formed through
which a loose spindle is permitted to freely work or traverse therein as also in
a bearing provided upon the other end or extremity of the Cock, Tap or Valve, to
which a suitable handle is fitted, the said spindle having at the latter extremity
a pin or stud fitted thereto working in a concentric slot, groove or opening formed
in the said Cock, Tap or Valve. At the fore or other end of the same, which would
be attached in any suitable manner to the supply, I provide a truc or flat surface or
circular face to receive a conical or tapered circular washer of suitable metal
working therein and loose upon the spindle, to the extent permitted, by means of
a reduction in its diameter forming a shoulder thereon; behind the aforesaid
conical or tapered circular washer I provide a Valve of suitable metal or material
recessed to the necessary extent on its inner portion so as to contain an elastic ring
or washer of india rubber or other suitable material as may be found necessary in
practice, which is likewise arranged so as to traverse or work freely upon the
spindle or rod and secured in position by means of a bolt or nut on the end of the
spindle so that immediately or instantly the handle or lever is turned, either to
the right or left to the extent required for the purpose as may be arranged, the
water or other fluid or gas as the case may be is free to pass through and find
a free exit in that portion of the casting provided therefor, and instantly upon the
handle being released the pin or stud fitted into the spindle and working in
the concentric slot, groove or opening formed in the said casting, and working
therein permits of the pressure immediately acting upon the Valve and conical
washer referred to and so works and aids to effectually and securely cut off and
close the exit passage.

I SAMUEL ALBERT JOHNSON of 24 Glengall Road, Poplar, Middlesex, Marine
Engineer do hereby declare the nature of my invention for "AN IMPROVED
AUTOMATIC SELF CLOSING VALVE OR TAP," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement and accompanying drawing:-
The object of this Invention is to freely permit of water, gas or other liquid or
fluid under pressure passing and being regulated at will and to arrange for the
Valve or Tap being instantly closed on the handle being released and securely
checking any waste or escape, this I effect in the following manner.
I take or form a casting somewhat similar to the ordinary Cock, Tap or Valve in
use of suitable shape, open at one end to admit of the passage of water or other
fluid or gas, but having a bar or guide cast therein with an opening formed therein
through which a loose spindle is permitted to freely work or traverse therein as
also in a provided bearing at the other end or extremity of the Cock, Tap or Valve
to which a suitable handle is fitted, the said spindle having at the latter extremity
a pin or stud fitted thereto working in a concentric groove, slot or opening formed
in the said Cock, Tap or Valve. At the fore or other end of the same is attached
in any suitable manner to the "supply" a true or flat surface or circular face to
receive a conical or tapered circular washer of suitable metal working therein loose
upon the spindle to the extent permitted by means of a reduction in its diameter
forming a shoulder thereon; behind the aforesaid conical or tapered circular washer
I provide a valve of suitable metal or material recessed to the necessary extent on
its inner portion so as to contain an elastic ring or washer of india rubber or other
suitable material, as may be found necessary in practice, which is likewise arranged
to traverse or work freely upon the spindle or rod and secured in position by means
of a bolt or nut on the end of the spindle, so that immediately or instantly the
handle or lever is lifted or turned either to the right or left to the extent required
for the purpose as may be arranged, the water or other fluid or gas as the case
may be is free to pass and find a free exit in that portion of the casting provided
therefor, and instantly upon the handle being released the pin or stud fitted into
the spindle and working in the concentric slot, groove or opening formed in the
said casting and working therein, permits of the pressure immediately acting upon
the Valve and conical washer referred, to and so works and aids to effectually and
securely cut off and close the exit passage.
Figure 1, is a sectional view. Figure 2, is an end view and Figure 3, is a plan
referring to the method I propose to adopt in practice, in which the letters referring
to same correspond in each case, that is to say A, is the handle or lever which
actuates the spindle B, having the conical or tapered circular washer C, loose upon
the spindle B, and permitted to freely work by means of a reduction in its diameter
fitting upon or working against the casting or bearing of the Valve or Tap G, in
which a bar or guide is cast or formed therein H, with a suitable opening through
which the spindle B, is permitted to traverse and freely work as against an elastic

page_text: ring J, or washer of India rubber or other suitable material as may be found
desirable in practice, which is so arranged as to be freely acted upon and be com-
pressed in its seating as shewn, and held in position by means of a bolt or nut on
the end of the spindle B, so that immediately the handle or lever is lifted or raised
to the required angle permitted and necessary as may be arranged either to the
right or left, either the fluid or gas as the case may be is instantly free to pass
through and find a speedy and free exit from that portion of the casting as shewn
at K, upon the handle or lever being released working as against the pin or stud L,
fitted into the spindle and working in the concentric groove or opening M, formed
in the said casting and working therein, permitting of the pressure of either fluid
or gas immediately acting upon the Valve and conical or tapered circular washer C,
referred to and so works and effectively aids in cutting off automatically the exit
passage as vice-versa the ingress is permitted.
The screwed part of the casting N, as shewn in Section Figure 1 and Plan
Figure 2, can be inserted into or connected with a Tank, Barrel or Pipe as may be
desired.
The India Rubber ring or other elastic washer bearing upon the seating when
the Valve is closed helping to create and make a perfect joint without leakage.
The Washers can be easily taken out at any time and if needed cleansed or renewed
at a very small cost.
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
The general arrangement of a Tap, Valve or Cock as herein described; the
form proportion or shape of which may be varied to suit the particular purposes
for which it may be intended and for regulating at will the passage of Water, Gas
or other liquid or fluid and preventing any waste or escape by means of the conical
or tapered circular washer and seating working as against an elastic ring or medium
substantially as herein set forth.
