page_text: I, WILLIAM HENRY WOOLLATT, of Millicent Road, West Bridgford, Notting-
hann, Insurance and Commision Agent, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to an improved measuring tap designed to meet the
requirements of dealers in liquids vended in measured quantities, and consists
of a measuring tap in which the several features hereinafter described are com-
bined in co-operative relation.
In carrying out the invention, I make the tap-body of dimensions appropriate
to the desired capacity, and of any desired shape, preferably making it vertical
and cylindrical. I form its bottom with a single central opening adapted to serve
both for the inlet and the outlet of the liquid, and to such bottom opening I
apply a four-way connection having opposite lateral branches respectively leading
from the reservoir of the liquid and to the receptacle of the measured liquid and
respectively adapted with unions for connection with the liquid inlet and outlet
piping or tubing, and having other opposite branches crossing and communicating
with the lateral branches, and being internally coned and adapted to receive a three-
way cock or plug which has an axial opening always in connection with said single
central opening of the tap-body and two angularly disposed lateral openings both
in connection with said axial opening and respectively adapted to communicate,
one at a time, with the liquid inlet and outlet lateral branches of the four-way
connection, the bottom branch of the connection being adapted with a stuffing
box and union for securing the cock or plug in position and through which the
plug projects and is fitted with a turning handle.
The top of the tap-body is open and is fitted with a removable tap or cover
having an upwardly extending flange adapting it to serve as a froth overflow
receptacle. The cap is formed with a central opening also having an upwardly
extending flange formed with through holes, the flange being adapted to serve
as a guide to a float valve by which the opening is closed as the tap-body fills,
and the through holes serving to allow of the return of the froth liquid as the
tap body empties. The inner end of the central flanged opening is coned flush
with the inside top of the cap and adapted to act as a seating to the float valve
which is coned and formed with feather guides adapted to work within the flange
of the central opening, the valve being adjustably mounted on a finely screwed
wire, upon which, at a lower location, a cork float is adjustably mounted between
locating washers. Externally of the tap, the central flange is fitted with a domed
cap having a central opening just sufficiently large to admit of the screwed pin
passing therethrough, and, externally of the dome, the pin is fitted with an adjust-
able nut adapted to close the opening when the valve is unsupported by the liquid
and the tap is emptying, and to uncover the same when the liquid, in filling the
tap-body, rises to the float and lifts the valve. thus permitting of the escape of
any froth which may first exude from the tap body into the said flanged

page_text: The tap handle, at the bottom end of the tap-body, is provided with an extension
which serves the two purposes of actuating a suitable counter mechanism, and
of raising a guided rod which, at its top end, is connected to a lever mounted on
the flanged cap and adapted, when the tap-body is desired to be emptied, to
depress the valve against the lifting tendency of the float, so as to allow of the
inlet of air into the tap-body through the said side holes in the central flanged
part and other holes in said adjustable nut and of the free escape of the liquid.

improvements in Measuring Taps.
I, WILLIAM HENRY WOOLLATT, of Millicent Road, West Bridgford, Notting-
ham, Insurance and Commision Agent, 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 invention relates to an improved measuring tap designed to meet the
requirements of dealers in liquids vended in measured quantities, and consists
of a measuring tap in which the several features hereinafter described are com-
bined in co-operative relation.
The improved tap is represented on the accompanying drawings in Figures, 1,
and 2, in elevation, in views at right angles to each other, and partly in section;
showing the parts in the relative positions occupied when the tap is emptying.
In carrying out the invention, the tap body, a, is made of dimensions appro-
priate to the desired capacity and may be made of the shape represented on the
accompanying drawings or of any other desired shape. Its bottom, b,
is formed with a single central opening, c, adapted to serve both
for the inlet and the outlet of the liquid to be measured, and with
a connection, d, in connection with lateral branches, e, f, the former being in
connection with a reservoir (not shown) of the liquid to be measured and the
latter acting as the outflow, for the measured liquid, the connection, d, also
having a coned through-way, g, communicating with the branches, e, f, and
adapted to receive a two or three way cock or plug, n, formed with ports or open-
ings adapted to communicate with the opening, c, of the measuring tap body, and,
one at a time, with the liquid inlet and outlet lateral branches, e, f, and fitted
with a turning handle, s.
The top of the tap body is open and is fitted with a removable cap or cover, t,
having an upwardly extending flange, u, adapted to serve as a froth overflow
receptacle, a central opening, &, and an inner flange, w, having through holes, x,
at its lower part leading to the opening, v, the flange, w, being adapted to serve
as a guide to a float valve, y, by which the opening, v, is closed as the tap body
fills, and the holes, a, serving to allow of the return of the froth liquid into the
tap body as the latter empties. The opening, v, is coned flush with the inside
top of the cap, t, and serves as a seating to the valve, y, which is likewise coned
and adjustably. mounted on a finely screwed wire, z, which is fitted with feather
guides, 7, adapted to work within the flange, w, and at a lower location with a cork
float, 2, which is adjustably mounted between locating washers, 3. Externally
of the tap,. the flange, w, is fitted with a domed cap, 4, having a central opening, 5,

page_text: through which the pin, z, works freely. Internally of the dome, the pin, z, is
fitted with a cupped attachment, 6, serving to prevent any liquid which may
escape past the valve at the moment of its closing from escaping through the
opening, 5, and externally of the dome the pin is fitted with an adjustable nut, 7,
adapted to cover the opening, 5, when the valve is unsupported by the liquid and
the tap is emptying, and to uncover the same when the liquid, in filling the tap
body, rises to the Hoat and lifts the valve, thus permitting of the escape of any
froth which may exude from the tap body into the said Hanged receptacle.
The tap handle, s, at the bottom end of the tap body is provided with an exten-
sion, 8, which serves the two purposes of actuating a suitable counter mechanism
(not shown) and a suitably guided rod, 9, which, at its top end, is connected to a
lever, 10, mounted on the cap, t, and adapted by bearing on the valve stem
nut 7, when the tap body is desired to be emptied, to depress the valve against
the lifting tendency of the float so as to allow of the inlet of air into the tap body
through the openings, x, and of the free escape of the liquid.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
The improved measuring tap hereinbefore described with reference to the
accompanying drawings.
