PROVISIONAL SPECIFICATION.
An Improved Construction of Sluice-valve.
We, CHARLES BILLINGTON Senr., and JOHN NEWTON Longport, Stoke-on-
Trent, Staffs. Brass Founders, do hereby declare the nature of this invention to be
as follows: -
This our invention has reference to an improved construction of sluice valve, and
the object of our said invention is the construction of such valves which have a
hollow spindle, with an external projecting collar or ring around and near to the
lower end of such hollow spindles, which collar bears upon a metallic plate fitted
or fixed in a recess formed in the upper part of the body or casing of such valves,
the said plate, collar and spindle being retained in their proper positions by the
lower portion of the stuffing box, by which means the force or pressure exerted
when opening or closing such improved valves is resisted, instead of the exerted
opening force having to be resisted by the packing in the stuffing boxes of similar
valves as generally made, beside which the stuffing boxes of our improved
valves can be more readily packed, and we find that the packing has longer
duration.
When the several parts of our improved sluice valves are fitted or fixed together,
the passage of steam, water or other fluid is stopped by its gate or divided valve,
which valve fits between seatings formed in the lower part of the body or casing
of such valves.
When such a valve is being opened or removed from its seating by means of a
suitable hand wheel or lever fitted or fixed at the upper end of its hollow spindle,
the lower internally screwed portion of the said hollow spindle when rotated causes.
the upper part of the threaded spindle of the valve to rise up into the hollow
portion of the said hollow spindle, at the same time drawing or sliding the hollow
divided gate or valve from between its seatings by means of the cuneate or wedge
shaped lower end of the threaded valve spindle, which wedge shaped portion
when the valve is in its seating tends to force the two parts of the valve apart
against their respective seating so as to ensure tightness of fit, and prevent
leakage.

COMPLETE SPECIFICATION.
An Improved Construction of Sluice-valve.
We, CHARLES BILLINGTON Senr., and JOHN NEWTON, Longport, Stoke-on-
Trent, Staffordshire, Brass Founders, 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 :-
This our invention relates to an improved construction of sluice valve, the object
of our invention being to construct such valves which have a hollow elongated nut
or outer spindle in such a manner that the pressure required to open or close such
valves will be efficiently resisted by means of a metallic plate, and a collar on the
lower end of the said hollow spindle or sleeve.
To carry our said invention into practice we make the elongated metal nut or
outer spindle of such valves with a metallic collar or ring around and near to the
lower end of the said outer spindle, which collar bears upon a metallic plate fitted

page_text: or fixed in a recess formed in the upper part of the metallic body or casing of such
valves, the said plate, collar and elongated nut being retained in their proper
positions by the lower portion of the stuffing box, by which means the force or
pressure exerted when opening or closing such improved valves will be efficiently
resisted, instead of the opening and closing forces having to be resisted by the
packing in the stuffing boxes of similar valves as generally made.
When the several parts of our improved sluice valves are fitted or fixed together,
the passage of steam, water or other fluid is stopped by its "gate" or divided
metallic valve which fits between seatings formed in the lower part of the body or
casing of such valves.
In order that our said invention may be more readily understood and explained
in detail we have hereunto annexed a sheet of drawings on which letters of reference
are marked on corresponding parts on all the figures alike.
DESCRIPTION OF DRAWINGS.
Figure 1 is a side elevation of a sluice valve made in accordance with our
invention.
Figure 2 is a similar elevation to that shewn at Figure 1; but partly in
section.
"
In these figures a is the metallic body or casing of such valve, with a screwed
cover b, having a stuffing box formed in same, à screwed gland or nut c, an
externally screwed spindle d, the lower wedge shaped portion or head of which fits
into a recess formed in the divided "gate" or valve f, the upper part of the
screwed spindle d projecting a suitable distance into the internally screwed lower
portion of the elongated nut or sleeve g, the upper end of the said sleeve being fitted
or provided with a suitable hand wheel h. When such improved valves are being
opened for permitting the flow of steam, water or other fluid through same by
lifting its divided "gate or valve f from between its seatings f", f³ by means of
its hand wheel fitted or fixed at the upper end of its elongated nut or sleeve g
the lower internally screwed portion of the rotated sleeve g causes the threaded
part of the spindle d to rise up into the hollow portion of the elongated nut or
sleeve g, and draw or lift the divided " gate or valve from between its
seatings by means of its wedge shaped lower end e, which wedge shaped
portion when the valve f is between its seatings f³, fs, tends to force the two
parts of the said divided "gate" or valve f against its respective seating so as
to ensure tightness of fit and prevent leakage, the pressure or force exerted in
opening such valves being resisted by the metallic plate i, the collar g' on the
lower part of the sleeve g, and the internal lower part or parts 63 of the screwed
cover b.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
The construction of sluice valves having an elongated nut or hollow spindle g
with a collar g³ around such spindle near to its lower end, a metallic plate i fitted
or fixed in a recess formed in the upper part of the metallic body or casing a, so
that the forces or pressure exerted in closing or opening such valves will be
efficiently resisted by the said collar g', metallic plate i, and the internal lower
part or parts 6 of the cover b, as herein substantially described set forth and fully
illustrated on the drawings hereunto annexed.
