page_text: and for Facilitating Repairs to Taps and Cocks.
I, JOHN CREIGHTON of 4 St. Joseph's Road, Hornsey, in the County of
Middlesex, Plumber, 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 :—
With the taps and cocks at present in use for drawing off water and other
liquids, no provision is made for checking the supply of water or other liquid
when the tap or cock is out of order. Such tap or cock has to be detached from
the supply pipe in order to be repaired, and the liquid thus released is allowed to
run to waste, or else the whole supply is turned off at the main. In the case of a
number of taps being supplied from one main it is obviously a great inconvenience
if all of these taps are deprived of their supply, (as in large houses, hotels and other
buildings,) during the temporary removal of one or more of the taps.
My invention is intended to overcome the disadvantages referred to, and it is
equally applicable to tanks, cisterns, vats and other large vessels used by brewers
and others for the storage of liquids as by means of my improved regulating valve,
taps and cocks can be removed from these vessels without the loss of a single drop
of the liquid contained therein, and so simple is the whole contrivance that the
mere action of inserting the tap or cock in the boss immediately reopens the valve
and allows of the free passage of the liquid again.
This my invention relates to that class of mechanism known as Regulator
Valves by means of which the supply of water from the main is regulated or
effectually cut off, and I will now proceed to describe the same, reference being
had to the drawings hereunto annexed and the figs. and letters of reference marked
thereon, similar letters of reference indicating corresponding parts on all the
figs. alike.
Fig. 1 is a part sectional elevation of my invention showing the tap in place and
the valve open to its full extent, allowing the maximum quantity of liquid to flow
in its course.
Fig. 2 is a sectional elevation showing the tap removed and the valve pressed
home on its seating by the force of the liquid, thereby closing the aperture and
preventing exit of liquid.
Figs. 3, 4 and
mentioned valve.
are respectively end elevations and side elevation of the above
Fig. 6 is a sectional end view taken on the line X X in Fig. 1.
The socket A in combination with the socket a and the valve B show the main
portion of my invention, the whole of which is preferably constructed of brass, or

page_text: other suitable non-corrosive metal, and screwed on the inside of their larger
diameters, in the case of the socket A to receive the screwed part c of the tap C,
and in the case of the socket a to receive the outwardly screwed part d of the
socket A. On the outside circumference of the socket A is formed a hexagonal
nut a³ in one piece with the flange a¹ and the said socket A, more clearly shown
by reference to Fig. 6. The socket A and the screwed portion c of the tap C are
made of such a length, that by means of the screwing in or screwing out of the
tap C, together with pressure of water or other liquid on the valve, the spaces D, D
are proportionately increased or decreased, and it is by this means that the passage
of the water or liquid is regulated. When the tap C is screwed into the socket A
to its greatest extent, the screwed portion c rests on the lugs b³ to the guide 6 of
the valve B pressing it against the shoulder formed by the smaller internal portion
of the socket A and consequently pushing the valve B away from its seating d
and thus allowing a free passage for the water or other liquid in the direction
indicated by the small arrows. E is a portion of the main or other pipe through
which the water or other liquid is passing, and is represented partly in section,
showing a ready means of attaching socket a of my invention, and which may
be accomplished firstly by means of soldering in the usual manner, brazing or
screwing, as may be most convenient. In order to obtain a perfectly water tight
joint between the sockets A, a, I insert a leather washer or washers F, which by
being compressed tightly between the shoulders formed by the variable diameters
of the sockets A, a, forms an easily operated and perfect water tight joint. I may
employ other means of effecting this object, such as the insertion of white or red
lead, or other suitable substance between the threads, but the former method being
more cleanly and easily performed is preferably used.
By the insertion of a leather washer or washers f a perfectly water tight joint is
made between the flanges c¹ of the tap C and the flange c² of the socket A. These
washers are of variable thicknesses so that by the insertion of respectively a thick
or thin washer the screwed part c of the tap C is allowed to enter more or less into
the socket A.
The valve B which is preferably made of brass or other suitable non-corrosive
metal is a combination of 3 parts, which are described as follows:-
The small disc b has formed at its centre a small screwed pin 6¹ in one piece
with it, and which is of such a length that it will readily admit of an india rubber
washer and the guide piece 6ª being screwed on to it, said guide, in combination
with the smoothly bored hole d³ in the socket A¹, being used for the purpose of
causing the valve B to travel in a horizontal plane with its seating d², the lugs b³
made in the same piece with the guide 6 holding the valve B in place and forming
surfaces against which the screwed portion c of the tap C presses when adjusted.
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-
The construction of a regulator valve in the boss between a tap of ordinary
construction and the pipe through which the water flows or between the tap and
the tank containing the water, substantially as, and for the purposes hereinbefore
described, set forth and fully illustrated in the drawings annexed.
