IMPROVEMENTS IN TAPS OR STOPCOCKS
Year: 1885

page_text: I, JOHN DUNBAR, of 102 Hyde Park Street, Glasgow, in the County of Lanark,
North Britain, Brassfounder, do hereby declare the nature of my said invention for
IMPROVEMENTS IN TAPS OR STOPCOCKS," to be as follows that is to say :-
68
My said Invention relates to taps or stopcocks which like those of domestic
water supply apparatus have to be in constant use, and its object is to make
provision for the unavoidable repairs or renewals of parts of such taps or stopcocks
being effected in the most convenient manner, and without having to interrupt
the supply of water by other taps or stopcocks connected with the same main
supply pipe.
My Invention consists in combining a conical-plug or screw plug valve with the
ordinary Lambert or screw-down tap or stopcock in such a way that when the
ordinary tap requires to be opened for renewing the diaphragm or washer
the additional valve may be closed so as to temporarily shut off the water without
its being necessary to interfere with the main supply pipe.
It will be obvious that the additional valve may be applied in various ways so
as to obtain the desired result the essential feature being its interposition between
the inlet of the ordinary Lambert or screw-down tap or stopcock and the pipe by
which the water is supplied. Thus the body of the additional valve may be formed
in the same piece or casting as the body of the ordinary tap or stopcock; or it may
be formed in a separate piece fixed immediately on the end of the water supply
pipe and fitted for having the ordinary tap or stopcock connected to it in any
convenient way, and when this latter modification is adopted the ordinary tap or
stopcock can be completely removed when requiring repairs or renewal.

I, JOHN DUNBAR, of 102 Hyde Park Street, Glasgow, in the County of Lanark,
North Britain, Brassfounder, 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 that is to say:-
My said Invention relates to taps or stopcocks which like those of domestic
water supply apparatus have to be in constant use, and its object is to make
provision for the unavoidable repairs or renewals of parts of such taps or stopcocks
being effected in the most convenient manner, and without having to interrupt the
supply of water through other taps or stopcocks connected with the same main
supply pipe.
My Invention consists in combining an additional conical-plug or screw-plug
valve with the ordinary Lambert or screw-down tap or stopcock in which a flexible
diaphragm is used requiring frequent renewal. The body of the additional valve
may be formed in the same piece or casting as the body of the Lambert tap; or it
may be formed in a separate piece fixed immediately on the end of the water
supply pipe, and fitted for having the ordinary Lambert tap connected to it in any
convenient manner; and when this latter modification is adopted the ordinary
Lambert tap can be completely removed when requiring repairs or renewal.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and representing examples of taps or stopcocks as made
with my improvements.
Figures, 1, and 2, on the accompanying sheet of drawings are side and back
elevations of a tap or stopcock with movable crane or discharge spout suitable for
kitchen or scullery sinks or jawboxes; and figure, 3, is a vertical section. Figures, 4,
and 5, are side and back elevations of a tap or stopcock for similar purposes, with
the body of the Lambert tap arranged so that it can be completely removed; and
figures, 6, and 7, are corresponding vertical and horizontal sections. Figure, 8, is
a vertical section of a nose cock as fitted with my improved additional valve in
the form of a screw plug. In these drawings the same reference numerals are used
to mark the same or like parts wherever they are repeated.
In the example shown in figures, 1, 2, and 3, the additional valve, 10, is in the
form of a conical plug, which is fitted to work in a conical socket formed in the
same body or piece, 11, as that having formed in it the passages and port face of
the Lambert tap, 12, the axis of the conical plug, 10, being across the inlet pipo, 13,
and at right angles to the axis of the Lambert tap, 12. With this arrangement
the square-ended spindle, 14, of the conical plug, 10, is conveniently accessible;
whilst the handle, 15, of the Lambert tap, 12, is at least as conveniently placed for
use as in ordinary arrangements. A gland, 16, with packing is provided in the
opening through which the spindle, 14, projects. The conical plug, 10, is made
hollow or with a passage having ports at right angles to each other so as when
placed in the "open" position to afford a passage from the inlet pipe, 13, to the
Tamhaut dan 19

page_text: In the example shown in figures, 4, 5, 6, and 7, the additional valve in the form
of a hollow conical plug, 10, is fitted into the end of the inlet pipe, 13; and this
end is made with a branch, 17, which is formed with a conical socket to receive
the end, 18, of the inlet part of the Lambert tap, 12, the part, 18, being secured
by a screw nut, 19, and made tight by means of washers. With this arrangement,
when the additional valve, 10, is closed, the Lambert tap, 12, can be completely
removed, without having to shut off the supply of water to the inlet pipe, 13.
The example, shown in figure, 8, is an ordinary Lambert nose cock but with a
screw plug, 20, fitted to bear up when closed against a seat formed on the under
side of the orifice through which the water ordinarily has access to the diaphragm, 21,
and outlet, 22.
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
1. The combination of an additional conical-plug or screw-plug valve with a
Lambert tap or stopcock substantially in the manner and for the purposes herein-
before described.
2. The attaching of a tap or stopcock to the supply pipe with a screw coupling
or its equivalent in combination with the fitting of the supply pipe with a separate
valve substantially as and for the purposes hereinbefore described.
