PROVISIONAL SPECIFICATION.
Improvements in Valves, Taps, and Water Gauges.
I, MARK LANGDALE SYKES, Commercial Foundry, 11 Pritchard Street,
Manchester, Engineer do hereby declare the nature of this invention to be as
follows
An improved arrangemant of valve for admitting & shutting off steam, gas,
water or air. The improvement consists of a sliding valve, working without
saraws or threads on the spindle, inside of the usual valve body, on a suitable-
seat. The valve, or the seat, or both valve & seat may be made of either metal,
woodite, asbestos, vulcanised fibre or other suitable material. The seat may be
either part of or fixed in the dividing bridge of the valve, or attached in a suitable
Caner thereto for removal & renewal when required. The valve may be made in
the usual manner as a single stop valve or cock, or attached to water gauges, or
may be made as a double valve, in which latter case the arrangement of the valve
and spindle on the underside of the valve bridge may be the same as on the upper
side thereof, so that the valve may be worked or closed from the under side when
required, without shutting off pressure from the valve.
This arrangement of sliding valve without screws or threads on the spindle is
applicable to all forms of valves & taps working under pressure.

COMPLETE SPECIFICATION.
Improvements in Valves, Taps, and Water Gauges.
I MARK LANGDALE SYKES of Union Street Foundry, No. 1 William Street,
Ardwick, in the City of Manchester Engineer, 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 :—
The said invention relates to valves taps & water gauges employed for the
purpose of admitting and shutting off steam gas water or air. The improvement
consists of a sliding valve working without screw or thread on the valve spindle
inside a usual valve body on a suitable valve seat. The sliding valve or the seat
or both valve and seat, may be made of either metal, woodite, asbestos, vulcanised
fibre or other suitable material. The seat may be either part of or fixed in the
valve bridge, or may be attached in a suitable manner thereto for removal and
renewal when required. The valve may be made either as a single stop valve or
cock or attached to water gauge cocks, or may be made as a double gauge cock, or
may
be made as a double valve in which latter case the arrangement of the valve
and spindle and seat on the underside of the valve bridge may be the same as on
the upper side thereof, so that the valve may be opened & closed from either side
indifferently, or the seats or valves or any parts thereof may be removed and
renewed as required, without pressure being shut off from the valve.
In order that the invention may be thoroughly & readily understood I have
provided one sheet of drawings to accompany this Specification of which the
following is a description.
Fig. 1 in the said drawings represents a vertical section through the centre of
the valve, and Fig. 2 a horizontal section of the same.
A is the valve body, B is the spindle, C the valve, D the seat, and E the bridge
of the valve. The valve C the sant D and the brides
aimlas

page_text: provided with an aperture or apertures K of suitable area to the size of the valve
inlet and so arranged that each aperture is opposite the other, arid a full and clear
way is through when the valve is open and when pressure is passing through.
When the pressure is not required to pass, the valve C is turnell, part way round,
so that the surface of the valve face C which is not cut away clozes the aperture K
over the seat D and the bridge E & pressure is thus out of and the valve or tap is
closed. When the valve is made as a double valve, as shown in the drawings, this
may be done with either the top or bottom valve as desired The spindle B is
made to work in and is held in position by nuts and glands FH & 1 and with
packing G of either woodite, yarn, fibre, asbestos or other suitable material
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I dealare that what I
claim is
1. The arrangement of sliding valve without screws or threads for actuating the
working of same for all forms of valves and taps under pressure substantially as
set forth and indicated.
2. The arrangement of sliding valve without screws or threads for actuating the
working of same in conjunction with a movable and renewable seat or seats and
valve valve or valves for all forms of valves and taps under pressure cubstantially
as set forth and indicated.
3. The arrangement of aperture in valves seats and bridges for all forms of
valves and taps under pressure substantially as set forth and indicated.
