PROVISIONAL SPECIFICATION.
An Injector and Ejector Stop Tap.
We, ARTHUR CRAVEN, and FREDERICK CRAVEN, of Waterloo Mills, Bradford, in
the County of York, Spinners, WILLIAM PINDER, of the same place Engineer, and
PETER HENRY STANSFIELD, of Leeds Road, Bradford, aforesaid, Plumber, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is the construction of a tap in which by a novel
arrangement of the openings in the tap casing and through the plug therefor, a
better circulation of water or steam is obtained through heated vessels of machines
such as combs, drying cylinders, heating pipes and such like, in which the outlet
from the same is conducted into other pipes or vessels under pressure; and to so
arrange the tap that the opening through the plug may be cleared of sediment,
whenever necessary whilst under pressure, and without having to remove it from the
casing.
We accomplish the above object by forming in the tap casing three openings,
arranged by preference to be opposite each other, one opening in connection with
the supply being on one side of the casing, and two openings on the other or outlet
side, the last named openings being some distance from each other.
The plug of the tap is constructed with a conical hole through the same, cut in
a diagonal direction and in such position, that when the plug is turned to one position
all openings through the tap are closed: when turned so that the larger diameter of
the conical opening is opposite the supply pipe it acts as an injector; allowing steam
or water to pass from one vessel or series of pipes under pressure to another; and
when turned with its smaller diameter to the last named position, any sediment, or
foreign matter that may have been deposited, or become fast in the conical opening
of the plug, is ejected to the atmosphere, or open vessel as the case may be, without
having occasion to remove the plug from the tap casing.

COMPLETE SPECIFICATION.
An Injector and Ejector Stop Tap.
We, ARTHUR CRAVEN and FREDERICK CRAVEN, of Waterloo Mills, Bradford, in
the County of York, Spinners, WILLIAM PINDER, of the same place, Engineer, and
PETER HENKY STANSFIELD, of Leeds Road, Bradford, 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 :-
The object of this invention is the construction of taps in which by a novel
arrangement of the openings in the casings and through the plugs therefor, a better
circulation of water or steam is obtained through heated vessels of machines such
as combs, drying cylinders, heating pipes and such like, in which the outlet from the
same is conducted into other pipes or vessels under pressure: also to so arrange the
taps that the opening through the plug may be cleared of sediment whenever
from the casing.
necessary whilst under pressure, and without having to remove
In the accompanying drawings, Fig. 1. represents a sectional elevation through the
centre of a tap made according to our invention, and Fig. 2. is a similar view with
plug reversed or turned to the opposite side.
In each tap casing A. are formed three openings B. C and D. arranged by preference
to be opposite each other-that is in the same line as the flow of the steam or

page_text: liquid, the opening B. in connection with the supply being on one side of the
casing A. and the other two openings C and D. on the outlet side of the tap casing,
and some distance from each other.
The tap plug E. of each is constructed with a conical hole F. through the same,
cut in a diagonal direction, and in such position, that when the plug is turned so
that the conical opening F. is at right angles to the openings B and C. all commu-
nication through the tap is closed; and when turned so that the larger diameter of
the conical opening is opposite the supply pipe or opening B. it acts as an injector;
the pressure in the pipe or opening B. flows through the conical opening F. and by
it acting on the larger diameter of the said opening, the steam or water is forced
or injected through the smaller diameter at the termination of the conical opening
into a vessel or pipe under pressure connected to opening C.; and when the plug E.
is turned with its smaller diameter to the supply pipe or opening B. any sediment
or foreign matter that may have been deposited or become fast in the conical
opening F. is by the pressure or force of steam or other fluid in supply pipe B.
ejected to the atmosphere or an open vessel as the case may be, without having
occasion to remove the plug E. from the tap casing A.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
-
Taps having three openings through the casing A. combined with a plug E.
having a conical opening F. passing through in a diagonal direction, all being
arranged substantially in the manner as shown and hereinbefore described."
