AN IM- PROVED TAP FOR MEASURING, REGULATING, REGISTERING, VENTILATING, AND PREVENTING THE WASTE OF FLUIDS AND LIQUIDS.”
Year: 1876

page_text: LETTERS PATENT to Ridley Henderson, of Timsbury, near Bath, in the County
of Somerset, Civil and Mining Engineer, for the Invention of "AN IM-
PROVED TAP FOR MEASURING, REGULATING, REGISTERING, VENTILATING, AND
PREVENTING THE WASTE OF FLUIDS AND LIQUIDS.”
PROVISIONAL SPECIFICATION left by the said Ridley Henderson at the
Office of the Commissioners of Patents on the 18th October 1876.
RIDLEY HENDERSON, of Timsbury, near Bath, in the County of Somerset, Civil
and Mining Engineer. "AN IMPROVED TAP FOR MEASURING, REGULATING,
REGISTERING, VENTILATING, AND PREVENTING THE WASTE OF FLUIDS AND
LIQUIDS."
My Invention consists of a tap made with two reciprocating valves connected
with a receiver between them, fitted with registering indicators to measure and
prevent any waste of oil, wine, spirits, ale, water, and other fluids, and is constructed
with an inlet stem or tube with stop valve of the usual form to. connect at one end
with the main cask, jar, or other vessel, and at the other end with the upper edge
or surface of the measurer, which should be of some stated imperial capacity. At the
bottom of the said measurer is an outlet tube fitted with the other stop valve; these
two stop valves or taps together with the registering indicators are worked
simultaneously by means of a key turning spur and bevel wheels with spring catch,
so arranged that when the key is turned the requisite distance the inlet tap or valvo
is open for the fluid to run from the vessel into the receiver, the outlet tap or valve is
closed, and vice versa, thus enabling the receiver to fill and then to empty alternately,
and to register on the indicators the number of times it is so filled, and also sup-
plying to the cask or vessel the requisite volume of air to occupy the place vacated
by the fluid. The receiver should be made of glass or metal and graduated to various
capacities, and for the purpose of allowing any lesser portion than the whole of its
contents to be drawn off when required, an additional tap or valve is placed in the

RIDLEY HENDERSON, of 48 and 49, the Albany, Liverpool, in the County of
Lancaster, late of Timsbury, near Bath, in the County of Somerset, Civil and
Mining Engineer. "AN IMPROVED Tap for Measuring, REGULATING, REGISTERING,
VENTILATING, AND PREVENTING THE WASTE OF FLUIDS AND LIQUIDS."
My Invention consists of a tap made with two reciprocating valves or plugs con-
nected with a receiver between them, fitted with registering indicators to measure
and prevent any waste of oil, wine, spirits, ale, water, and other fluids, and is
constructed with an inlet stem or tube with a stop valve or plug to connect at one
end with the main cask, jar, or other vessel, and at the other end with the upper
edge or surface of the measurer, which should be of some stated imperial capacity.
At the bottom of the said measurer is an outlet tube fitted with the other stop
valve or plug; these two stop valves, plugs, or taps, together with the registering
indicators, are worked simultaneously by means of a key turning wheels with or
without spring catch, so arranged that when the key is turned the requisite distance
the inlet tap or valve is open for the fluid to run from the vessel into the receiver,
and the outlet tap or valve is closed, and vice versa, thus enabling the receiver to fill
and then to empty alternately, and to register on the indicators the number of times
it is so filled, and also supply to the cask or vessel the requisite volume of air to
occupy the place vacated by the fluid. The receiver should be made of glass or
netal and graduated to various capacities, and for the purpose of allowing any
lesser portion than the whole of its contents to be drawn off when required an
additional tap, plug, or valve is placed in the outlet stem or tube for that purpose.
The above arrangements will effect ventilation.
