ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent. "AN IMPROVED APPARATUS FOR HOLDING AND FOR DRAWING OFF
IN MEASURED QUANTITIES OIL OR OTHER LIQUID." [A communication from abroad
by James Minot Thayer, of Randolph, in the County of Norfolk, State of Massa-
chusetts, United States of America.]
The object of this Invention is to furnish air tight liquid cabinets so constructed
that oil or other liquid can be drawn in any desired quantity without drip or waste
or the escape of odors.
The Invention cousists in constructing a liquid cabinet with an outer case, an
inner case provided with inlet and discharge openings, a measure provided with inlet
and discharge openings, and devices for opening and closing the discharge opening
of the inner case and admitting air to take the place of the withdrawn liquid, as
will be hereinafter fully described.
The outer shell or case of the cabinet is provided with a hinged top or cover, and
is supported upon feet at such a height that any ordinary receiving can or vessel
may be placed beneath its bottom. Within this case is placed the inner case or
tank, which is made of zinc, and may be divided into two compartments by a vertical
partition. Openings are formed in the top of the inner case, through which the oil
or other liquid is poured in, which openings are closed by screw plugs or caps. In
the forward part of the bottom of each compartment of the inner case is formed a
discharge opening, through which the oil or other liquid escapes into the measure,
and which is closed by a valve. The valves are packed with rubber or other
suitable material, and are held down by spiral springs interposed between them and
Price Cal

page_text: arched bars attached to the bottom of the inner case. To the stems of the valves
are attached the lower ends of wires, which pass up through holes in the top of
the inner case, and their upper ends are attached to the ends of levers, which are
provided with valves to close the holes through which the wires pass, and which
prevent the escape of odor into the room. These valves are thus opened to admit
air when the discharge valves are opened to draw out the liquid, and are closed
when the said valves are closed.
The levers are pivoted to supports attached to the top of the inner case, and to
their other ends are attached the upper ends of wires, which pass down between the
outer and inner cases, and their lower ends are attached to the outer ends of
arins, whose inner ends are attached to the spindles of knobs which pass in through
holes in the front of the case, so that the valves may be opened to draw off the
liquid by turning said knobs. The measure is made of such a size as to contain a
gallon or any other desired quantity, and is secured beneath the forward part of the
bottom of the inner case, with its forward part projecting in front of the outer case,
where it is covered with a projecting part of the latter case. In the bottom of the
measure is formed a discharge opening which is closed by a valve packed with rubber
or other suitable material, and held down by a spiral spring interposed between it and
an arched bar attached to the bottom of the said measure. To the stem of the valve
is attached the lower end of a wire which passes up through a hole in the top of the
measure, and has its upper end attached to the the end of a lever. This lever is pivoted
to a support attached to the top of the measure, and its other end projects at the side
of the said measure, and is connected with the end of a bent lever which is pivoted at
its angle to the side of the measure, or to a support attached to the said side. The free
. end of this lever is bent outward, to serve as a handle for convenience in operating it
to discharge the contents of the measure into a receiving vessel. Within the measure
is placed a float, to which is attached the lower end of a rod passing up through a
hole in the top of the measure, and into the space between the fronts of the outer
and the inner cases, and to the upper end of the rod is attached a cord which passes
over a pulley pivoted to a support attached to one or the other of the cases. The
other end of the cord is attached to the shank of an index finger, which shank passes
in through a slot in the front of the outer case, so that the said index finger may be
upon the outer side of the said case, and may point to the division marks of an
index plate attached to the front of the said case at the side of the slot, so that by
looking at the position of the finger the operator can see how much oil or other :
liquid bas entered the measure, and can close the valve as soon as the desired
quantity has entered the measure. A drip cup is placed beneath the discharge
opening of the measure, arranged to be slid in beneath the measure, and from which
the drippings are received in a vessel placed beneath the cabinet. A telescopic or
extension tube is interposed between the measure outlet and the can or other
receiving vessel, which when not in use can be placed in the measure or in & receiving
socket connected with the measure.

"AN IMPROVED APPARATUS FOR HOLDING AND FOR DRAWING OFF
IN MEASURED QUANTITIES OIL OR OTHER LIQUID." A communication from abroad
by James Minot Thayer, of Randolph, in the County of Norfolk, State of Massa-
chusetts, United States of America.
The object of this Invention is to furnish an air tight liquid cabinet so constructed
that oil or other liquid can be drawn in any desired quantity without drip or waste
or the escape of odors.
The Invention consists in constructing a liquid cabinet with an outer case, an
inner case provided with inlet and discharge openings, a measure provided with
inlet and discharge openings, and devices for opening and closing the discharge
opening of the inner case and admitting air to take the place of the withdrawn
liquid, all as will be hereinafter fully described.
In the accompanying Drawing Figure 1 is a front elevation of the apparatus
partly in section; Figure 2 is a sectional end elevation taken through the line x, x,
Figure 1; Figure 3 is a sectional elevation of the discharge tube. Similar letters
of reference indicate corresponding parts.
A represents the outer shell or case of the cabinet, which is provided with
a hinged top or cover a', and is supported upon feet a at such a height that
any ordinary receiving can or vessel may be placed beneath its bottom. Within
the case A is placed an inner case or tank B, which is made of zinc and may
be divided into two compartments by a vertical partition b. In the top of the
inner case B are formed openings 62, through which the oil or other liquid is
poured in, and which are closed by screw plugs or caps C. In the forward
part of the bottom of each compartment of the inner case B is formed a discharge
opening b³, through which the oil or other liquid escapes into the measure D,
and which is closed by a valve E. The valves E are packed with indiarubber or
other suitable material, and are held down by spiral springs F interposed between
them and the arched bars G attached to the bottom of the inner case B. To the
stems of the valves E are attached the lower ends of wires H, which pass up through
holes in the top of the inner case B, and whose upper ends are attached to the ends
of levers I. The levers I are provided with valves J to close the holes through
which the wires H pass, and which prevent the escape of odor into the room.
The
valves J are thus opened to admit air when the valves E are opened to draw ont
the liquid, and are closed when the said valves E are closed. The levers I are
pivoted to supports attached to the top of the inner case B, and to their other ends
are attached the upper ends of wires K which pass down between the outer and
inner cases A, B, and are attached at their lower ends to the outer ends of the arms
L. The inner ends of the arms are attached to the spindles of the knobs M.,
which pass in through holes in the front of the case A, so that the valves E, J,
may
be opened to draw off the liquid by turning the knobs M. The measure D is made
of such a size as to contain a gallon or any other desired quantity, and is secured
beneath the forward part of the bottom of the inner case B, with its forward part
projecting in front of the outer case A, where it is covered with a projecting part of
the said case A. In the bottom of the measure D is formed a discharge opening d',
which is closed by a valve Q packed with indiarubber or other suitable material,
and held down by a spiral spring R interposed between it and the arched bar $
attached to the bottom of the said measure D. To the stem of the valve Q is
attached the lower end of the wire F, which passes up through a hole in the top of
the measure D, and is attached at its upper end to the end of a lever U. The lever

page_text: U is pivoted to a support attached to the top of the measure D, and its other end
projects at the side of the said measure D, and is connected with the end of a bent
lever V which is pivoted at its angle to the side of the measure D or to a support
attached to the said side. The free end of the lever V is bent outward to serve as
a handle for convenience in operating it to discharge the contents of the measure D
into a receiving vessel. Within the measure D is placed a float W, to which is
attached the lower end of a rod X passing up through a hole in the top of the
measure D and into the space between the fronts of the outer and the inner cases A
and B, and to the upper end of this rod is attached the end of a cord Y, which passes
over a pulley Z pivoted to a support attached to one or the other of the cases A, B.
The other end of the cord Y is attached to the shank of an index finger A¹, which
shank passes in through a slot in the front of the case A, so that the said index
finger A¹ may be upon the outer side of the said case, and may point to the division
marks of the index plate B' attached to the front of the said case at the side of the
said slot, so that by looking at the position of the finger A' the operator can see
how much oil or other liquid has entered the measure D, and can close the valve E
as soon as the desired quantity has entered the said measure. Beneath the discharge
opening is placed a drip cup N, which is arranged to be slid in beneath the
measure D, and from which the drippings are received in a vessol placed beneath
the cabinet.
O is a telescopic or extension tubo to be interposed between the outlet a' and the
can or other receiving vessel, and which when not in use can be placed in the
measure D or in a receiving socket connected with the said mensure.
Having described the nature of the Invention, and the manner of performing the
same, I declare that what I claim as the Invention to be protected by the herein-
before in part recited Letters Patent is,-
The combination of the outer case A, the inner case B provided with the inlet
and discharge openings, the measure D provided with the inlet and discharge
openings, the spring valve E, F, G, the wire H, the lever and valve I, J, the wire
K, and the arm and knob L, M, substantially as herein shown and described.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Third day of June, in the year of our Lord One
thousand eight hundred and eighty.
