Improvements in Screw-down Taps or Valves.
I, WILLIAM PERRY of 6 Wellesley. Temace,Kilburn Lane,. Queen's Park.
Londen N.W. Plumber do hereby declare the nature of this.invention to be as.
follows:
This invention relates to improvements in screw-down taps or valves and has. for:
object to provide in a simple and effectual manner suitable means for preventing.
leakage throughthe taporovalve and consequent waste of water.
To accomplish this object:I have in addition to the ordinary screw-down valve"
upon the usual seatinginther tap, a second or auxiliary valve situate against a
seating provided in water iulet of the tap. This second or auxiliary valve-hás a
horizontal. travel and at its inner side is provided with an extension having
a slanting or sloping end which is acted upon by an inverted cone shaped block
formed at the lower: endsof a dependent spindle formed beneath the usual screw--
down valve. The spindles of these two valves when in position lie at right angles
to one another. As the ordinary screw-down valveris opened it is raised from its
seats and thus opens, the water passage to outlet. As it rises the inverted 'cone
shaped block at end of its spindle below the valve is also raised and this acting.
upon the correspondingly sloped or slanting end of the auxiliangewalver spindle
forces said auxiliary valve from its seating and allows the water from inlet to pass
through passage controlled by the usual screw-down valve and thus on to outlet.
To close the valve the ordinary screw-down-valve-is-turned-in the usual manner
and the auxiliary valve being acted upon by the pressure of the water from main
and the conical actuating block being also lowered with the screw-down valve
clear of the slanting end of the auxiliary valve said auxiliary valve is forced back
to its seating and thus controls the inlet of the tap. Hence in accordance with
this invention leakage is prevented by the action of the double valves and waste
entirely obviated.

Improvements in Screw-down Taps or Valves.
WILLIAM PERRY 6 Wellesley Terrace Kilburn Lane Queen's Park
London NW. 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 :——
A spindle continued through valve having an ordinary seating, & at continuation,
fitted with a cone, & slide, by which the valve is closed at 2 points the full
description of working in this valve as shewn in drawing herewith is as follows.
A. is a wheel, screw & spindle fitted through centre of valve with stuffing box I.
on which is fitted a rubber or cone valve B. which screws on seating J. Under-
neath on spindle, is fittal a slotted cone C. this coue hus a vertical slot working on
Price Sd.

page_text: a stud of an inch square on spindle to prevent its changing its position on spindle
fastened by nut H. & the spindle is extended into cap G. opening wheel lifts
valve B. off seating J. & cone C. which pushes back & keeps open slide automatic
valve D. against pressure kept in central position by cross bar inside receiving
chamber E. which screws over outside of valve F. Closing wheel closes valve B.
pushes down cone C. & pressure of steam or water closes automatic slide valve D.
This valve can be repaired under pressure by observing the following conditions viz.
To repair valve B. unscrew cap G. Take off nut H. & coue C. & unscrew
top of valve 1.
To repair automatic slide valve unscrew receiving chamber E. screwed over
outside of valve F. & take out skide valve D.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is
1st. Double action high pressure steam or hot water valve. That by opening
wheel of valve opens 2 valves in 2 places one in front of pressure & one against
pressure by the action of cone & slide apparatus fitfed inside valve working
vertical & horizontal to one another. Closing valve closes vertical valve & back
pressure of steam or hot water closes horizontal slide automatic valve, more the
pressure on this valve sounder the valve.
2nd. That the valve can be repaired under any pressure either of steam or hot
water.
3rd. That the greater the pressure the greater the security of valve &
4th. That the principle of this valve cau be adapted to bib cock, stop cock steam
or hot water valves.
