1, WILLIAM HENRY TYLOB, of 2 Newgate Street, in the City of London, Brass-
founder do hereby declare the nature of this invention to be as follows:—
This invention relates to improvements in that description of cock, tap, or valve, in
which the outlet orifice is opened or closed by means of a loose or detached valve-piece
actuated by a screwed spindle or other suitable mechanism operated from the exterior
of the said cock, tap, or valve, either by hand, by a ball-float-lever, or otherwise, and
the object of this invention is to enable the said loose or detached valve-piece to be
removed for repairs, or for other purposes, without shutting off the supply at the main
or detaching the entire cock, tap, or valve, or allowing the escape of any considerable
quantity of water.
In manufacturing cocks, taps, or valves in accordance with my present invention, I
suitably connect the said loose valve-piece with the ordinary actuating mechanism and
also with a second spindle or other suitable device which may also be actuated from
the exterior of the cock, tap, or valve, for the purpose of disconnecting the said loose
valve-piece from the ordinary actuating mechanism and withdrawing it from its normal
position over the outlet orifice, into a recess or chamber provided for that purpose in
the body of the cock, tap or valve. This recess or chamber is preferably closed at its
outer end by a water-tight plug or cap,
The inner end of the ordinary valve-spindle, or other actuating mechanism, is
furnished with a supplementary valve which serves to close the outlet orifice in place
of the loose valve when required.
When it is desired to remove the loose valve-piece for repairs or otherwise, it is first
raised from its seat by means of the valve-spindle or other actuating mechanism in the
usual way and is withdrawn from its normal position over the outlet orifice and free

page_text: from the ordinary actuating mechanism into the before-mentioned recess or chamber
by means of the before-mentioned second spindle or other withdrawing device. The
outlet orifice is then closed by means of the supplementary valve on the inner end of
the ordinary valve-spindle or other actuating mechanism and the water is thereby shut
off. The plug or cap of the recess or chamber may then be removed and the loose
valve-piece taken away for repairs or otherwise. The plug or cap may then be
replaced, and the tap, cock, or valve is again in working order, even while the loose
valve-piece is under repair.

WILLIAM HENRY TYLOR, of 2 Newgnie Street, in the City of London, Brass Founder
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, reference being had to the accompanying sheet of Drawings, and to the
letters and figures marked thereon, that is to say :-
This invention relates to improvements in that description of cock, tap, or valve in
which the outlet orifice is opened or closed by means of a loose or detached valve-
piece actuated by a screwed spindle or other suitable mechanism operated from the
exterior of the said cock, tap or valve, either by hand, by a ball-float lever, or other-
wise, and the object of this invention is to enable the said loose or detached valve-
piece to be removed for repairs, or for other purposes, without shutting off the supply
at the main, or detaching the entire cock, tap or valve, or allowing the escape of any
considerable quantity of water.
In manufacturing cocks, taps or valves in accordance with my present invention, I
arrange the aforesaid loose valve-piece so as to be acted upon by the ordinary actuating
mechanism, and connect it with a second spindle or other suitable device, which may
also be actuated from the exterior of the cock, tap, or valve, for the purpose of
removing the said loose valve-piece from the action of the actuating mechanism, and
withdrawing it from its normal position over the ontlet orifice, into a recess or chamber
provided for that purpose in the body of the cock, tap or valve. This recess or
chamber is preferably closed at its outer end by a watertight plug or cap. The inner
end of the ordinary valve spindle or other actuating mechanism is furnished with a
supplementary valve which serves to close the outlet orifice in place of the loose valve
when required.
In the Drawings hereto annexed Figure 1 is a sectional elevation of a screw-
down tap constructed with my improvements applied thereto; Figure 2 is a front
elevation of same with one half of above mentioned watertight cap removed.
Figure 3 is a partial elevation, parily in section, of a lavatory screw down iap also
with my improvements applied thereto. Similar letters of reference relate to like
parts in all the Figures of the Drawing.
A is the inlet water way with the usual valve seating B surrounding it. C is the
loose valve-piece adapted to close watertight against the valve seating B.
D is an
ordinary screw down spindle the lower end of which is adapted to bear on and to
press the loose valve-piece C against its seating. The spindle D is also provided at
its lower end with a conical valve E adapted to fit watertight into the conical water-
way A when the loose valve piece C is withdrawn, or it may be provided with any other
suitable valve adapted to close watertight against the valve seating B. The loose
valve-piece C is hinged or otherwise loosely connected to the piece so as to be free to be
raised off its seating by the issuing liquid when the spindle D is raised. The piece F
is free to slide in the recess or chamber G, and is forined with an undercut groove Ft

page_text: into which is passed the collared end of a screwed spindle H which passes through a
tapped hole in the cap 1, secured over the end of the recess or chamber G. The outer
end of the spindle H is furnished with a square or other means by which it may be
turned.
When it is desired to remove the loose valve-piece C for repairs or otherwise, it is
first released from its seat B by unscrewing the spindle D more or less; it is then
withdrawn from its normal position over the waterway A, away from under the
spindle D and into the recess or chamber G by unscrewing the spindle H. The
waterway A is then closed by screwing down the spindle D until the valve E on its
end comes to bear against its seating and the water is thereby shut off.
The plug or
cap I covering the end of the recess or chamber G may then be removed, and the
loose valve-piece C taken away for repairs or otherwise. The plug or cap I with its
spindle H may then be replaced and the tap is again in working order, the valve E
on the end of the spindle D being used to allow or to stop the passage of water instead
of the loose valve piece C. When the loose valve-piece C has been repaired, or it is
desired to place a new one in the tap, the spindle II is unscrewed so as to draw the
piece well towards the cap I and the latter with the spindle H and piece Fare
removed from the tap the loose valve-piece C is hooked on to the piece F and together
therewith is passed into the recess or chamber G and the cap I is secured in place.
The spindle is then screwed upwards, the spindle H is screwed forward pushing
the loose valve-piece into its normal position on its seating B, the recess or chamber G
being so shaped or provided with guides as to conduct the valve-piece to its place,
the spindle D is then screwed down on to the valve-piece C and the tap is restored to
its normal condition.
It is obvious that similar arrangements may be readily applied to cocks, taps or
valves in which the valve actuating mechanism consists of a spindle sliding
longitudinally instead of a rotating screwed spindle. Also that the spindle for
withdrawing and replacing the loose valve-piece may be arranged to slide
longitudinally instead of being a rotating screw. Also that the valve actuating
spindle, besides being adapted to press the valve piece C against its seat, may he adapted
to raise the same from its seat by any suitable means, such for example, as those shown
for connecting the sliding piece F to the screwed spindle II.
flaving now particularly described and ascertained the nature of the said inven-
Lion and in what manner the same is to be performed, I declare that what I
claim is :-
In a cock, tap, or valve, the loose or moveable valve-piece C with means capable of
being operated from the exterior of the said cock, tap, or valve, for withdrawing the
said valve-piece from its seat into a recess or chamber G, and for returning the same
from the said recess or chamber to its seat and a supplementary valve E for closing
the waterway when the valve piece C is withdrawn from its seat, arranged, combined,
and operating, substantially as hereinbefore described, and illustrated in the Drawings
hereunto annexed.
