the City of London, for the Invention of "IMPROVEMENTS IN COCKS OR
TAPS."
Sealed the 18th July 1862, and dated the 18th March 1862.
PROVISIONAL SPECIFICATION left by the said Frederick Warner at
the Office of the Commissioners of Patents, with his Petition, on the
18th March 1862.
I, FREDERICK WARNER, of 8, Crescent, Cripplegate, in the City of London,
5 do hereby declare the nature of the Invention for "IMPROVEMENTS IN COCKS
.OR TAPS," to be as follows:-
This Invention has for its object improvements in cocks or taps. For
these purposes on the valve spindle is formed a toothed rack which is received
-into and works within the water or steam way of the tap or cock. The face
of the valve is by preference circular, and is packed with a soft packing where
it comes against its seat, which is preferred to consist of a projecting ring
.with a thin edge to enter the packing in the face of the valve. Or the seat
may be packed or have a washer of soft material, and the projecting ring
may be on the face of the valve. The toothed rack used is constructed...as

page_text: follows: There is a slot formed through an extended portion of the spindle
of the valve, on the inner surface of one side of which slot the teeth forming
the toothed rack are formed in such manner that when the pinion used with
the rack is in its place, the diameter of the pinion nearly corresponds with
the width of the slot. The axis of the pinion passes through a suitable stuffing
box into the interior of the body of the cock or tap. This stuffing box is
constructed in such manner that by screwing down the packing which takes
its bearing on, the axis, the requisite friction is obtained to resist the tendency
of the axis to turn with the force of the pressure of the fluid. It is preferred
that the arrangement should be such that about a quarter turn of the axis of
the pinion should be sufficient for opening and closing the valve. The lower
end of the axis of the pinion is pointed and has its bearing in a suitable cup.
The guide spindle of the valve is made three sided, the sides being hollow as.
heretofore, so that the water or steam or other fluid may pass freely on the three
sides of the spindle, whilst the three angles of the spindles serve to keep the
valve and spindle correctly in the water or steam-way. It is preferred that
the valve should be arranged to open with the pressure of the water or other
fluid, but this is not essential, as the valve may be arranged to open against
the pressure of the fluid.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Warner in the Great Seal Patent Office, on
the 18th September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
WARNER, of 8, Crescent, Cripplegate, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors,; give and grant unto me,
the said Frederick Warner,. Her special licence that I, the said Frederick
Warner, my executors, administrators, and assigns, or such others as I, the
said Frederick Warner, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might, make, use,
exercise, and vend, within the United Kingdom of Great. Britain and; Ireland,
the Channel Islands, and Isle of Man, an Invention for: "IMPROVEMENTS IN
Cocks OR TAPS," upon the condition (amongst others) that I, the said

page_text: Frederick Warner, my executors or administrators, by an instrument in
writing under my, or. their, or one. of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six, calendar months next, and imme-
diately after the date of the said Letters Patent..
NOW KNOW YE, that I, the said Frederick Warner, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:

This Invention has for its object improvements in cocks or taps. For
these purposes on the valve spindle is formed a toothed rack which is received
into and works within the water or steam way of the tap or cock. The face
of the valve is by preference circular and is packed with a soft packing where
it comes against its seat, which is preferred to consist of a projecting ring with
a thin edge to enter the packing in the face of the valve. Or the seat may
be packed or have a washer of soft material, and the projecting ring may be
on the face of the valve. The toothed rack used is constructed as follows:
There is a slot formed through an extended portion of the spindle of the
valve, on the inner surface of one side of which slot the teeth forming the
toothed rack are formed in such manner that when the pinion used with
the rack is in its place, the diameter of the pinion nearly corresponds with
the width of the slot. The axis of the pinion passes through a suitable
stuffing box into the interior of the body of the cock or tap. This stuffing
box is constructed in such manner that by screwing down the packing which
takes its bearing on the axis the requisite friction is obtained to resist the
tendency of the axis to turn with the force of the pressure of the fluid. It
is preferred that the arrangement should be such that about a quarter turn
of the axis of the pinion should be sufficient for opening and closing the
valve. The lower end of the axis of the pinion is pointed and has its bearing
in a suitable cup. The guide spindle of the valve is made three sided, the
sides being hollow as heretofore, so that the water or steam or other fluid
may pass freely on the three sides of the spindle, whilst the three angles of
the spindle serve to keep the valve and spindle correctly in the water or
steam way. It is preferred that the valve should be arranged to open with
the pressure of the water or other fluid, but this is not essential, as the valve
may be arranged to open against the pressure of the fluid.
Having thus stated the nature of my said Invention I will proceed more
fully to describe the manner of performing the same.

page_text: DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 shew sections of two cocks or taps constructed according
to my Invention. a is the valve, which in Figure 1 opens with the pressure
of the fluid, whilst the valve shewn by Figure 2 is arranged to open against
the pressure of the fluid; 6 is the spindle of the valve which is formed with a
slot through it, and cogs or teeth are formed on the interior. The valve
is formed hollow in the face and is packed with vulcanized india-rubber or
other suitable material. The valve is provided with a projecting guide a'
which is triangular and bears at three points, leaving sufficient space between
the guide and the barrel for the passage of the fluid; c is the spindle of the
pinion d, by which the rack and its valve is moved to and fro. The spindle c
may be formed suitable to receive a moveable key or a fixed handle. The
passage of the spindle c into the body of the cock is packed as shewn.
Having thus described the nature of my Invention and the manner of
Performing the same, I would have it understood that I make no claim
to any of the parts separately, but I claim the combined arrangements herein
described.
In witness whereof, I, the said Frederick Warner, have hereunto set
hand and seal, this Seventeeth day of September, in the year of
our Lord One thousand eight hundred and sixty-two.
my
FREDERICK WARNER. (L.S.).
