Improvements in Valves and Cocks.
I WILLIAM JONES Engineer No. 35 Wells Street Camberwell London do hereby
declare the nature of this invention to be as follows:-
The working parts are all made flat and smooth and easily removable from their
seats by the most simple tools so that a laborer or unskilled workman can when the
working parts are worn out of truth remove those working parts and restore them to
truth by rubbing or grinding them on any flat surface with or without any abrading
material. This invention improvement or method applies to all Valves or Cocks that
can be fitted with perfectly flat and smooth and detachable working faces.
For example to illustrate the method in the case of screw down Valves or Cocks
with a metal S shaped diaphram that is cast in one piece with the body or shell of
the Valve or Cock and in which diaphram there is a conical opening or passage, I,
in place of a conical opening, screw into the opening or passage a perfectly flat ring
for the seat and instead of a conical bulb on the bottom of the screw down spindle
I screw on the bottom of the spindle a perfectly flat and smooth disc which when
screwed down on the flat ring seating perfectly closes the passage and in case the
ring seating or the flat disc gets out of order they can be removed & ground true
and replaced by the aforesaid simple means.
As a further illustration. In the case of full way through screw down stop Valves
or Cocks I put an internal screw thread in both inlet and outlet ends of the body or
shell of the Valve or Cock into which I insert a sleeve or tube threaded to fit, the
iner ends of these sleeves or tubes are made perfectly flat and smooth and on the
outer ends I leave a swell of hexagon or other shape for a wrench to couple on to
screw up the face of the inner end to meet the face of the plug or stop on the bottom
of the screw down spindle.
On the outer ends of the body or shell of the Valve or Cock I leave an annular
recess next the inner screw thread to receive packing and on the sleeve or tube 1
screw a gland to fit the recess to keep the packing tight and so secure that part from
leaking. On the bottom of the screw-down spindle of Valve or Cock I make a groove
in which I hang the plugs or stops which plugs or stops I prefer to make in two parts
of the shape of an acute angle and fix thein in the grooves base upwards, the straight
sides of these angle shaped plugs or stops are made perfectly flat and smooth and
placed in the Valve or Cock chest point downwards and there kept in place and
guided by lugs or grooves cast in the inside or chest of the body of the Valve or
Cock so that when they are screwed they slide on the faces of the inner ends of the
sleeves or tubes which are screwed into the body of Valve or Cock and thus effectually
stop the passage through the Valve or Cock.
It will he needless to describe every sort or shape of Valve or Cock to which these
perfectly flat and smooth and easily removable working faces can be applied, but it
will be plainly seen that when the working parts or faces of Valves or Cocks are made
on this flat and smooth and easily removable principle that they can be taken out &
apart, repaired, and replaced, to be as good as new by the simple means herein described
without the aid of skilled workmen or lathe or other machine and without, as the
practice has been hitherto sacrificing the most expensive and costly part or body or
hell of the Valve or Cock.

Improvements in Valves and Cocks.
WILLIAM JONES 35 Well Street Camberwell 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:-
-
My invention consists in the simple and cheap construction of valves or cocks and
is carried out in the following manner.
The working parts are all made flat and smooth and easily removable from their
seats by the most simple tools so that a labourer or unskilled workman; can, when the
working parts are worn out of truth, remove these working parts and restore them to
truth, by simply rubbing or grinding them on any flat surface, with or without an
abrading material such as sand, emery etc.
This improved construction applies to all valves or cocks which can be fitted with
perfectly flat and smooth detachable working faces or seatings.
To illustrate the application of my improvements, I take as an example the case
of a screw down valve or cock, with an S shaped diaphragm, which is cast solid with
the body or shell of the valve or cock.
In this diaphragm there is a conical opening or passage closed by a conical plug
secured to the end of the screw down spindle. By my invention 1 dispense with the
conical or taper passage and plug, by screwing into the opening a flat ring of metal
which forms the seat and substituting for the conical, a perfectly flat disk, smooth,
and fixed to the screw down spindle, in such a way as to give the disk a little lateral
play or endway. This disk when screwed down on the flat ring or seating will adjust
itself so as to lie quite flat on the said ring or seating.
As a further illustration of the adaptability of my invention I may instanco the case
"full-way through screw down stop cock or valves. Fig. 2.
of a
"
.
I put an internal thread in both inlet and outlet ends of the valve or cock into
which I insert a sleeve or tube threaded to fit. The inner ends of these sleeves or
tubes are made perfectly flat and smooth and on the outer ends I have a swell of a
hexagon or other shaped head to enable a screw wrench or spanner to be used to
screw up to the face of the of the inner end to meet the face of the plug or stop
on the bottom of the screw down spindle.
On the outer ends of the body or shell of the valve or cock, Fig. 2. I leave an
annular recess h¹ next the inner thread to receive packing and on the sleeve i or tube
I screw a gland to fit the recess, to keep the packing tight and secure that part
from leaking.
On the bottom of the screw down spindle of the valve or cock, I make a groove to
which I hang the plug or stop which plug or stop I prefer to make in two parts,
(having cast on their backs a semicircular lug or projection for seating the disk
squarley) in the shape of an acute angle, fixing them on the grooves base upwards,
the straight side of this angle shaped plug or stop is made quite smooth and
perfectly flat, and placed in the valve chest point downwards. They are kept in
place and guided by lugs or grooves, cast in the inside, or chest of the valve or cock,
so that when they are screwed down, they slide on the faces of the inner end of
the sleeve or tube which is screwed into the body of the valve or cock and thus
effectually stop the passage through the valve or cock.
It is needless to describe every valve or cock to which this invention may be
applied, but it will be plainly seen that the working faces or seats may be taken out
and apart, repaired and replaced, without the aid of skilled labour, lathe, or other
machine, besides doing away with the practice as hitherto pursued viz. the sacrifice of
the most expensive part, namely the body or shell of a valve or cock.
In the accompanying drawings
Fig. 1. is a section of an ordinary S diaphragm valve or cock.
Fig. 2. is a view of a "full way through screw down valve or cock partly in
section, similar letters of reference refer to similar parts.

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) In valves or cocks constructing the working parts flat and smooth and
easily removable from their seats, when the working parts are worn out of truth,
by simply rubbing or grin ling them on any flat surface, with or without an abrading
material, such as sand emery &c.
(2) In valves or cocks the construction and arrangement substantially as described
and shewn in the annexed drawing.
