page_text: LETTERS PATENT to Joseph James Liddon, of Winford Road, Islington, and
Fisher Howorth Simmonds, of New Charles Street, Goswell Road, both in
the County of Middlesex, for the Invention of "IMPROVED VALVE COCKS OR
TAPS."
Sealed the 27th October 1877, and dated the 1st May 1877.
PROVISIONAL SPECIFICATION left by the said Joseph James Liddon and
Fisher Howorth Simmonds at the Office of the Commissioners of Patents on
the 1st May 1877.

IMPROVED VALVE COCKS OR TAPS."
«
Our Invention consists in improvements in cocks or taps, and same may be
applied for either hot or cold water, or steam, air or other fluids, as may be found
necessary.
Our Invention consists of the following arrangements, taking as an instance a
valve tap for supplying steam:-The arrangement of the inlet and outlet is as
usual, but in place of the valve arrangements we use substantially the following:-A
plug or valve provided with guides is so formed as to rest on the seat when closed;
to this plug or valve a screw rod or spindle is attached; over this rod is passed a
screw piece which is screwed into the chamber, and to make it a fixture a screw
passes through the chamber; above this is placed (in the chamber) a plug which fits
the same, said plug being, on its lower surface, provided with a screw which screws
into the spindle before mentioned, and on its upper surface is cast or fixed a spindle,
to which the wheel or handle for actuating the valve tap is secured. Over the
whole of the mechanism in the chamber we place (to keep same in position) a screw
or nut, which screws on to the chamber.
Various modified arrangements may, for facilitating the working parts, be adopted,
such as in place of the screw spindle we may use a cam, eccentric, or similar means,
the main point or feature being to enable the valve to rise and fall by the aid of
the top plug.

page_text: By using the arrangements as above set forth we dispense with the use of a
stuffing box, as at present in use, and avoid the waste of steam or other fluid which
issues through the stuffing box.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Joseph James Liddon and Fisher Howorth Simmonds in the Great
Seal Patent Office on the 1st November 1877.

This Invention consists in improvements in cocks or taps, and same may be

:-
The Invention consists of the following arrangements, taking as an instance a
valve tap for supplying steam :-The arrangement of the inlet and outlet is as
usual, but in place of the usual valve arrangements, substantially the following are
used A plug or valve provided with guides is so formed as to rest on the seat
when closed. To this plug or valve a screw rod or spindle is attached. Over this rod
is passed a screw piece which is screwed into the chamber, and to make it a fixture
a screw passes through the chamber into this screw piece. Above this, in the
chamber, is placed a plug which fits the same, said plug being, on its lower surface,
provided with a screw into which the spindle before mentioned screws, and on
its upper surface is cast or fixed a spindle, to which the wheel or handle for
actuating the valve tap is secured. Over the whole of the mechanism in the
chamber is placed (to keep same in position) a screw or nut which screws on to the
chamber.
Various modified arrangements may, for facilitating the working parts, be adopted,
such as in place of the screw spindle a cam, eccentric, or similar means, the main
point or feature being to enable the valve to rise and fall by the aid of the top
plug.
By using the arrangements as above set forth, the use of a stuffing box, as at 3
present in use, is dispensed with, and the waste of steam or other fluid which issues
through the stuffing box is avoided.
Thus far the nature of the said Invention has been described, and these presents
have incidentally intimated in what manner the same is to be performed or carried
out in practice; now therefore (aided by the accompanying Drawings) the said
Invention is herein-after further and particularly described and ascertained, as also
the manner in which the same is to be performed or carried out in practice, that is
to say,
-
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation of the improved cock or tap. Fig. 2 is a vertical section
(showing the cock or tap closed).
In these Figures A is the plug or valve resting when closed on the seat a, as in
ordinary cocks or taps. B, rod or spindle, which is formed square, and works in
guide C. This guide may form part of the screw piece D which is screwed into the
chamber E, as shown. The inner part of screw piece D is formed with the part d,
against which rests the ground in valve bottom E¹. This valve bottom E¹ is cast
with the spindle F, which has a hollow with screw thread, into which the thread of
the screw portion 6 of rod or spindle B works. G denotes the wheel for working
the valve or tap, same being secured by screw, as shown.
The action of the above described will be readily understood from the foregoing
statement upon reference to the accompanying Drawings.

page_text: Having now particularly described and ascertained the nature and object of the
said Invention and in what manner the same is to be performed or carried out in
practice, we hereby declare that we claim the Invention of "Improved Valve Cocks
or Taps," substantially as the same is herein-before set forth and described and
illustrated by the accompanying Drawings, the special point or feature whereof is the
herein-described construction of ground in valve or plug with hollow to admit screw,
whereby the necessity of the use of stuffing boxes is dispensed with, all substantially
as herein-before set forth and described.
In witness whereof, I, the said Joseph James Liddon, have hereunto set my
hand and seal, this First day of November, in the year of our Lord One
thousand eight hundred and seventy-seven.
