page_text: I, WILLIAM AMBLER, Patent Agent, of, 12, Bank Buildings, Bradford, in the
County of York, do hereby declare the nature of my said Invention, to be as
follows:-
This Invention relates to an improved construction and arrangement of portable
apparatus for filling gas meters and other vessels with liquids.
The improved apparatus consists of a closed portable can or cistern for containing
the liquid, and within which there is inserted a pumping apparatus the outlet from
which projects above the top or cover of the can or cistern and is adapted for the
secure attachment of a flexible pipe which is adapted for and intended to be
inserted into the inlet of the meter or other vessel in any convenient place, the
arrangement and connection of the parts being such that on actuation of the pump
the required amount of liquid is discharged from the can or cistern without waste
direct into the meter or other vessel.
The pumping apparatus, which, as aforesaid, is adapted within the containing
can or receptacle, is constructed with an ordinary pump barrel closed at the
top and having a check valve at its inlet, and within the pump barrel there is
fitted a piston formed with through openings which are covered with a flexible
valve which is so adapted as to uncover the said through openings upon the
downward pressure or stroke of the piston and to then admit the liquid from the
can or cistern into the barrel of the pump, and as to again cover the said openings
upon the lifting or return stroke of the piston (which may be effected automatically
if required) so as to force the liquid now contained in the barrel of the pump above
the piston through the said outlet into the delivery pipe. By this improved means
the necessity of any check valve in the outlet pipe is dispensed with.

I, WILLIAM AMBLER, Patent Agent, of, 12; Bank Buildings, Bradford, in the
County of York, do hereby declare the nature of the said 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 construction and arrangement of portable
apparatus for filling gas meters and other vessels with liquids.
The improved apparatus is illustrated on the accompanying drawing in sectional
elevation; and is constructed with a closed portable can or cistern, 1, for con-
taining the liquid, and within which there is inserted a pumping apparatus, 2, the
outlet pipe, 3, from which projects above the top or cover, 4, of the can or cistern,
and is adapted for the secure attachment of a flexible pipe which is adapted for
and intended to be inserted into the inlet of the meter or other vessel in any
convenient place, the arrangement and connection of the parts being such that on
actuation of the pump the required amount of liquid is discharged from the can or
cistern without waste direct into the meter or other vessel.
The pumping apparatus, is constructed with a pump barrel, 2, which is closed at
its upper part, 5, and is adapted with a check valve, 6, at its inlet, and is fitted
with a piston, 7, formed with through openings, 8, which are covered with a
flexible valve, 9, which is so adapted as to uncover the openings, 8, upon the down-
ward stroke of the piston, and to then admit the liquid from the can or cistern
through the check valve, 6, into the upper part of the barrel of the pump, and as to
again cover the said openings upon the lifting or return stroke of the piston, which
may be effected by hand, or automatically by a spring, 10, encircling the piston
rod, 11, or by other equivalent means, so as to force the liquid contained in the barrel
of the pump above the piston through the outlet into the delivery pipe, 3, the said
outlet being closed by the piston when at the top of its stroke. By this improved
means the necessity of any check valve in the outlet pipe is dispensed with.
The lid or cover, 4, is preferably concaved, and is adapted with a return inlet, 12,
at its lowest part to catch any drippings, and such inlet is adapted with a sieve, 13,
to prevent entrance of foreign matter thereinto, and with an upturned trap, 14,
fitted with a ball valve, 15, in a wire cage, 16, for use with petroleum or other
volatile liquids to prevent escape of vapor.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
The improved construction and arrangement of portable apparatus for filling gas
meters and other vessels with liquids substantially as herein before described with
reference to the accompanying drawings.
