THOMAS WILLIAM FRY CHERRY, of No. 3 Bell's Terrace, North Shields in
the County of Northumberland Marine Engineer do hereby declare the nature of
this invention to be as follows --
In the accompanying drawing Fig. 1 represents a transverse section of my tap
A being the body with through ways; B is the plug or key which operates the tap;
C is the passage or way by which the liquid flows through the key; D is a narrow
or neck part; E is a knob at bottom part of neck; Fis an india rubber washer
which is sprung on to the neck D and is prevented from slipping or coming off
by means of the knob E and by F coming into contact with the bottom of tap

grooved out cape on shoulder of the plug or key B. I (in dotted lines) represents
the iron handle cast into plug or key but made stronger than the crossheaded
handle G and terminating at top part with the square head J for fitting on a
spanner.
Fig. 2 is an elevation of the plug B part in-section, shewing section the iron
handle G.
The advantages and improvements in my tap are the following-1st. The iron
handle G cannot break by turning the plug around. 2nd. The cape H effectually
prevents any fluids rising beyond the inner or underside of it, thus the tap is
rendered perfectly safe whilst boing operated.

1, THOMAS WILLIAM FRY CHERRY, of 3 Bell's Terrace, North Shields, in
the County of Durham, Marine Engineer, do hereby declare the nature of this
invention und in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention has reference to the manner in which I construct taps for use with
chemical and other fluids; the object being to produce a tap which shall be less
liable to corrosion, safer, and more convenient to manipulate than is possible with
the existing ordinary taps now employed for such purposes.
In the accompanying sheet of explanatory drawings-
Figure 1 is a sectional elevation and Figure 2 an end elevation of my improved
tap when constructed with spigot ends.
Figure 3 is a sectional elevation and Figure 4 an end elevation when constructed
with screwed and bib ends.
In carrying my invention into effect I construct my tap with its body or case A

screwed spigot.euds B, or with'a'bib or month piece end C, Figure 3, to suit the
particular position it is required to work in; and I make the body and plug D in
lead regulus, metal, porcelain, vulcanite, or other suitable material for use with
the chemical or fluid which is to pass through it.
The plug I form with a recessed or necked lower end d for the purpose of
receiving a washer or keep E of india-rubber or like material, which I spring over
the enlarged terminal end D' of the plug so as to keep it in position within the
body of the tap. The upper part of the plug I provide with a projecting flange
like guard or cap D2 which I make preferably with a channeled or grooved under
surface d' so that any acid fluid which may happen to escape up the plug may be
prevented from rising to the handle or key which the operator has to manipulate.
cast a handle or lever head F of iron or other suitable material in the head of
the plug shaped to permit of a spanner being applied or of being turned by hand
as may be desired to suit any particular requirement. I make the passage Oiu
my plug to give a through way from one side to the other of the tap body in the
usual ordinary.manner, and when so required I may make a packing groove or
recess at the upper end for a ring of rubber or other suitable material to be
employed when making my plug parallel instead of tapered in its diameter.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is―
The improvements in cocks and taps for corrosive and other fluids, substantially
as.and for the purposes herein before described, and as illustrated in the accom-
panying drawings.
