Complete Specification Left, 10th Sept., 1898-Accepted, 5th Nov.,
1898
I, ANDREW WREN, of 167, King Street, Pollokshaws, Glasgow, Plumber and
Gas-Fitter, do hereby declare the nature of this invention to be as follows:-
―
This invention relates to water taps and it has mainly for its object to enable
the ordinary screw-down valve to be removed when necessary for repair without
necessitating the cutting off the water supply from the service pipes.
In carrying out my invention I make the water tap with two valves one the
ordinary screw-down valve and the other a plug valve which is fitted in the
passage leading to the screw-down valve. This passage is bored out with a
taper for the reception of a hollow tapered plug which works tight therein.
This plug has an opening or passage way at one side communicating with the
water supply passage and also a short spindle passing down through a stuffing
box and having at its lower and a suitable knob or handle.
By turning the plug valve the water can be cut off from the ordinary screw
down valve, and the latter can then be taken out of place, and cleaned or repaired
without water escaping from the tap.

Improvements in Water Taps,
I, ANDREW WREN, of 167, King Street, Pollokshaws, Glasgow, Plumber and
Gas-Fitter, 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:-
This invention relates to water taps and it has mainly for its object to cuable
the ordinary screw down valve to be removed when necessary for repair without
necessitating the cutting off of the water supply from the service pipes.
And in order that my said invention may be properly understood I have here-
unto appended an explanatory sheet of drawings, whereon,
Fig. 1 is a sectional view of a water tap as made in accordance with my
invention.

page_text: In carrying out my invention I make the water tap with two valves one the
ordinary screw down valve a and the other a plug valve (b) which is fitted in
the passage leading to the screw down valve. This passage which is marked e
on the drawings is bored out with a taper for the reception of the hollow tapered
plug which works tight therein in the same manner as an ordinary plug
cock. The plug 6 has an opening or passage way d, or a series of holes d
Fig. 2, at one side and this opening, whenever desired, can, by the turning of
the plug) be put into communication with the water supply passage h of the lap.
Whenever desired the plug can be turned so as to cut off communication between
the passage and the passage of the tap. Normally the plug is in the
position Fig. 1 so that the water supply is entirely controlled, as usual, by the
valve a. To enable the plug b to be turned it has a short downwardly projecting
spindle which passes through a central hole in the cap g and which is provided
with a key end f, or a knob or equivalent, whereby it may be turned. The
cap 9 has a screwed flange g' which screws on to the bottom extension i of the
tap is a pinching screw for locking the cap in position.
If desired instead of securing the plug in position by means of the cap g its
spindle may be passed through a stuffing box made in the extension i. In
this case of course the extension would be properly made so as to serve as a
stuffing box and be provided with a stuffing gland.
By turning the plug valve b the water can be cut off from the ordinary
screw down valvo and the latter can then be taken out of place and cleaned or
repaired without water escaping from the tap.
The invention can be applied to ordinary crane or swan neck taps.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I consider novel and desire to claim is :-
Water taps made with an auxiliary plug or valve so arranged that by operat-
ing such plug or valve the water can be cut off from the ordinary screw down
valve which latter can then be taken out of place and cleaned or repaired without
water escaping from the tap, substantially us herein before set forth.
Dated this 1st day of September 1898.
