IMPROVEMENTS IN VALVE TAPS
Year: 1886

page_text: 1, HENRY SHAW MOORE, of Ridgway near Chesterfield, in the County of Derby,
Engineer, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN VALVE TAPS" to be as follows:-
This invention consists of a valve tap applicable to water or other similiar
supply.
The essential feature of this invention consists in the construction of a tap the
valve seating of which is made more accessible than it is in the taps at present in
use thus rendering it easy to keep a good face on the valve seat.
By making the valve seat more accessible, that is, by arranging it in such a way
that when the valve box is opened the seat will be prominent I make it perfectly
easy to remedy any unevenness which may have been caused by the water coursing
through it.
This may be easily done by means of a smooth flat file or other suitable
instrument.
The part of the valve which is soldered to the service pipe is tube-shaped the
end forming the seat of the valve and being tapped to receive the valve-box and
spout which screw up against a flange or shoulder on the said tube the valve-box
being so made that space is left for the water to pass the valve which acts full in
the end of the pipe.
The opposite end (from the seat) of the valve-box is tapped to receive the spindle
which screws the valve onto its seat and which may be provided with a packing-
box and gland if deemed necessary.
By forming the seat on the end of a tube I cause the valve to open and close full
in the pipe or tube end of the tap which materially lessens the liability to crack
through unequal expansion and contraction.
The material employed and the general details of construction of this invention
may be similiar to that of ordinary taps, cocks, and the like articles.

page_text: I, HENRY SHAW MOORE, of Ridgway, near Chesterfield, in the county of Derby,
Engineer, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN VALVE TAPS," and in what manner the same is to be performed to be par-
ticularly described and ascertained in and by the following statement :-
This invention consists of a valve tap applicable to water or other similar
supply in which the waste of water caused by defective valve seating is easily
prevented.
The essential feature of this invention is in the construction of a tap, the valve
seating of which is made more accessible than it is in the taps at present largely
used, and which makes it perfectly easy to keep a good face on the valve seat.
By making the valve seat more accessible, that is by arranging it in such a way
that when the valve box is opened the seat will be prominent, it can readily be
examined whenever a new washer is put on the valve and any uneveness remedied
which may have been caused by the water coursing through it, and the trouble
and inconvenience of renewing the washers when the seating is at fault will thus
be avoided.
It will also be an advantage inasmuch as the water supply can be cut off by
simply unscrewing the valve and substituting a cap, which is screwed over
the seat.
The part of the valve called the tail-piece which is soldered to the service pipe,
is tube shaped, the outer end forming the seat of the valve and being tapped to
receive the valve-box and spout which screw up against a flange or shoulder on
the said tail-piece, the valve-box being so made that space is left for the water to
pass the valve which acts full in the end of the pipe.
The opposite end (from the seat) of the valve-box is tapped to receive the
spindle which screws the valve onto the seat and which may be provided with a
packing box and gland if deemed necessary.
The valve-box is formed in one piece with the spout but may be made otherwise
if desirable.
By forming the seat on the end of a tube I cause the valve to open and close
full in the pipe or tube end of the tap, which materially lessens the liability to
crack through unequal expansion and contraction.
The material employed and the general details of construction may be similiar to
that of ordinary taps, cocks, and the like.
The accompanying drawings illustrate my invention.
Fig. 1. is a longitudinal section shewing the packing box A; crotch or spindle B ;
valve C; washer D; and the seat of the valve E which is formed on the end of
the tube F.
Fig. 2. is a section shewing the application of the seat formed on the end of the
tube F in another design:
Fig. 3. is a view showing tail-piece or tube, and valve seat E.

page_text: 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
Firstly Improvements in the construction of a valve-tap the seating of which
is formed on the tail-piece of the tap in such a way that when the valve-box is
unscrewed it will leave the seating prominent, so that it can easily and readily be
examined and repaired.
Secondly Improvements in valve taps as herein before specified and described,
and as illustrated by the accompanying drawings.
