PROVISIONAL SPECIFICATION.
Improvements in Taps or Valves for Steam, Water, or other Fluids.
GEORGE HENRY KENDALL, 41 Union Street, Engineer, RICHARD GEE, New Hey
Road, Lindley, Engineer, & JOHN TYNE THORNTON, Paddock Engineer, all of
Huddersfield, in the County of York, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to improvements in that class of Taps or Valves principally
employed for steam, water, and other fluids. To carry out our invention, the barrel of
the tap is lined with a tightly fitting case of 'woodite,' conical in shape, & which is
held firmly in its position by slight projections in the casting, placed round the inner
openings of the thoroughfare. In practice we find when using taps, constructed as
hitherto, that owing to the extreme pressure brought to bear when turning the tap, &
the quantity of gritty matter, which is very often deposited between the plug & the
barrel, the metal becomes fluted or cut, thereby making the tap faulty. Now in order
to prevent this we insert between the plug & the barrel, a woodite' lining, which
being pliable, obviates the cutting or fluting of the plug or barrel.
By our invention, all grinding in of plugs is dispensed with.
The 'woodite' lining can be easily and quickly re-placed, thereby making the tap
practically new.

COMPLETE SPECIFICATION.
Improvements in Taps or Valves for Steam, Water, or other Fluids.
We, GEORGE HENRY KENDALL of 41 Union Street, Engineer, RICHARD GEE, of
New Hey Road, Lindley, Engineer, and JOHN TYNE THORNTON, of Paddock,
Engineer all of Huddersfield, in the County of York, 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 :-
Our invention relates to improvements in that class of tap or valve principally employed
for steam, water, and other fluids. Our improvements in such taps or valves consist
in lining the barrel of the tap with a tightly fitting case of woodite, conical in shape
so as to suit the plug fitting therein.
Such being the nature and object of our invention, we will now make reference to
the accompanying sheet of drawings illustrative thereof, wherein Fig. 1 is section of
a plug tap or valve having our improvements applied thereto. A represents the plug
of the tap, B the body of the said tap, the barrel of which is lined with woodite as
shewn at C. This woodite lining is held firmly in its position by one or more pro-
jections within the barrel, or the said woodite lining may be driven in tightly. Taps
and valves having woodite lining as shewn in the Drawings will resist the action of
acids and other corroding influences, and the usual grinding of the plug will not now
be necessary; but when the woodite is worn it can easily be replaced, whereby the
tube or tap becomes practically new again. Taps and valves without the woodite
lining are subjected to a great deal of wear and tear owing to the extreme pressure
brought to bear upon the parts when turning the tap, and the quantity of gritty
matter which is often desposited between the plug and the barrel, whereby the metal
often becomes fluted or cut, making the tap faulty thereby :-but such will not so

page_text: easily happen with taps having the woodite lining, as the woodite is pliable and not
so liable to be cut as metal.,
i
Having now particularly described the-nature of our said invention, and in what
manner the same is to be performed, we declare that what we claim is :—
The application of woodite lining to taps or valves for steam, water, or other fluids,
in manner substantially as herein shewn and described.
