An Improved or Tap
Year: 1898

page_text: I, EDWYN JOHN BARKER, Ellis Street, Sloane Street, Chelsea, Middlesex, Glass,
Lead, Oil and Color Merchant, do hereby declare the nature of this invention to be
as follows:
This invention consists of an improved valve or draw-off tap, the object being to
so arrange the valve that when it is required to renew the plug or seating the same
can be readily removed and the water supply prevented from escaping without the
necessity of shutting it off by means of a separate cock. In carrying out my
invention I provide a suitable plug which is carried in any suitable manner in a
socket piece which screws into or is attached to the bottom of the valve and is
operated by a handle; the rotation of this piece carrying the plug opening or closing
the outlet. Operated by this plug is a second plug so arranged that when the plug
is removed from the outlet for the purpose of allowing the passage of the water or
other liquid, this second plug falls with it but does not completely cut off the supply
during ordinary use, but when the piece carrying the plug is removed a sufficient
distance from its seating the plug closes the main supply aperture, thus preventing
the escape of water or other liquid, and the plug may then be repaired, the socket
piece again inserted, and the plug will again remove this second plug aforesaid from
its seating, thus rendering the tap ready for use.
An Improved valve or Draw-on Tap.
I, EDWYN JOHN BARKER, Ellis Street, Sloane Street, Chelsea, Middlesex, Glass,
Lead, Oil and Color Merchant, 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:-

Referring to the annexed drawings,
Figure 1 is a sectional elevation shewing my invention applied to a tap.
a is a plug or valve which closes the aperture 6 and is carried in the screw socket
piece c by means of the lugs d. The screw socket piece has a waterway in same,
e being the outlet. f is a supplementary plug which is carried on the plug a and
is so arranged that when the handle g is rotated sufficiently the plug f will close the
aperture 6 and so cut off the supply of water, h being the inlet. By rotating the
handle it will be seen that water can pass through the outlet e, the relative distance
between the plug a and the closing part of the supplementary plug f being so
arranged that the supply is not cut off by means of the plug when the tap is in
ordinary use, but when it is required to renew the plug a or to get to the interior of
the body of the tap it is only necessary to rotate the handle sufficiently until the
plug comes into contact with the opening b. The plug a and screw socket piece
may then be removed and any necessary repairs made.
.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In taps or valves of the class herein described: the combined construction and
arrangement of the various parts substantially as described and illustrated herein.
2. In draw-off taps or cocks: a supplementary plug arranged to open and close an
aperture in the body of the valve; said supplementary plug being operated by the
movement of the plug which regulates the supply of water passing through the tap;
said regulating plug being carried in a screw socket piece operated by a handle,
substantially as described and illustrated.
