Office of the Commissioners of Patents on the 25th August 1880.
EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 40, Southampton Buildings, Chancery Lane, in the County of
Middlesex. "IMPROVEMENTS IN. VESSELS FOR HOLDING MINERAL OILS OR OTHER
OILS OR LIQUIDS." [A communication from abroad by Gustavus Richter, of
Mildenau, in the Empire of Austria.]
This Invention relates to vessels used for holding or storing mineral, lubricating,
or other oils, such as petroleum or other oils, and more especially to such vessels
where a pump is used for the purpose of withdrawing the oil from the vessel, and
where the aperture through which it is discharged is arranged above an opening
in the cover of the vessel, through which any surplus or overflowing oil runs back
directly into the latter. I take a vessel or reservoir of sheet iron or other suitable
material in which the oil is stored, the vessel being closed at its upper end by a
cover, and being provided with a pump, the suction pipe of which descends to the
lowest part of the vessel, whilst its delivery pipe passes up through the cover for a
sufficient height, its discharge orifice being then turned downward so as to be in a
position above the centre of the cover, which is made concave outside, and is
provided with a small opening through which any surplus or overflowing oil passes
back into the vessel, a small pipe being fitted inside the orifice and its inner end
bent upward so as to serve as a syphon trap, through which the oil flows back.
The piston rod of the pump passes through the cover, and is fitted at its upper
end with a hinged ring or handle which can be fixed when desired by means of a
padlock to a book or fastening passing through the cover and attached to the
vessel.

page_text: The upper part of the delivery pipe is preferably bent or arched over in order
to strengthen it, its end being attached to the cover of the vessel, and the discharge
or outlet opening being arranged at its centre above the centre of the cover.
In order to withdraw oil from the vessel the padlock is unlocked, and the ring
or handle upon the piston rod being thus released is turned up and the pump
worked by it.
A valve box and valves are arranged upon the lower end of the pump, and the
liquid is forced up through the delivery pipe and escapes from the discharge
opening either into a vessel placed or held under it or through the hole in the cover
and the small syphon pipe back into the vessel.
The discharge pipe may be made sufficiently strong to carry it to any desired
height, and it may deliver the oil into a vessel in which it is measured, and whence
it is then discharged by means of a cock or valve into the vessel placed or held
under it.

by the said Edmund Edwards in the Great Seal Patent Office on the 25th
February 1881.
EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 40, Southampton Buildings, Chancery Lane, in the County of
Middlesex. "IMPROVEMENTS IN VESSELS FOR HOLDING MINERAL OILS OR OTHER
OILS OR LIQUIDS."
This Invention relates to vessels used for holding or storing mineral, lubricating,
or other oils, such as petroleum or other oils, and more especially to such vessels
where a pump is used for the purpose of withdrawing the oil from the vessel, and
where the aperture through which it is discharged is arranged above an opening in
the cover of the vessel, through which any surplus or overflowing oil runs back
directly into the latter.
The objects of the improvements are, first, improved methods of construction and
arrangements of the apparatus to allow the overflowing material to run back
directly to the reservoir; and, second, improved mechanism for keeping such
reservoir under lock and key.
In order to put the Invention in operation I take a vessel or reservoir of sheet
iron or other suitable material in which the oil is stored, the vessel being closed at
its upper end by a cover, and being provided with a pump, the suction pipe of which
descends to the lowest part of the vessel, whilst its delivery pipe passes up through
the cover for a sufficient height, its discharge orifice being then turned downward
so as to be in a position above the centre of the cover, which is made concave
outside, and is provided with a small opening through which any surplus or over-
flowing oil passes back into the vessel, a small pipe being fitted inside the orifice,
and its inner end bent upward so as to serve as a syphon trap, through which the
oil flows back.
The piston rod of the pump passes through the cover, and is fitted at its upper
end with a hinged ring or handle, which can be fixed when desired by means of a
padlock to a hook or fastening passing through the cover and attached to the
vessel. The upper part of the delivery pipe is preferably bent or arched over in
order to strengthen it, its end being attached to the cover of the vessel, and the
discharge or outlet opening being arranged at its centre above the centre of the
cover.
In order to withdraw oil from the vessel the padlock is unlocked, and the ring or
handle upon the piston rod being thus released is turned up and the pump worked
by it. A valve box and valves are arranged upon the lower end of the pump, and
the liquid is forced up through the delivery pipe, and escapes from the discharge
opening either into a vessel placed or held under it or through the hole in the cover
and the small syphon pipe back into the vessel.
The discharge pipe may be made sufficiently strong to carry it to any desired
height, and it may deliver the oil into a vessel in which it is measured, and whence
it is then discharged by means of a cock or valve into the vessel placed or held
under it.
The accompanying Drawing is in illustration of the Invention. Figure 1 is a
vertical section of the apparatus; Figure 2, a detailed section of the collecting
funnel; and Figure 3, a horizontal section through the cock following the dotted
line; Figure 4 is a plan of the reservoir; and Figure 5, a modification of the
funnel for reservoirs, provided with measuring apparatus; Figure 6 shows a section
of the measuring apparatus; and Figure 7, a side elevation thereof.
Similar letters refer to similar parts throughout the several Figures.
A is the tank, provided with a pump x, which is in connection with and delivers

page_text: into the discharge pipe g. The curved upper end of this pipe is bent just over tho
centre of the tank, and provided with a cock or with the measuring apparatus h,
in which the discharge pipe 9 goes up nearly to the top of h and is surrounded by
the larger pipe i; the latter has small openings at its lower end through which the
material runs into the glass tube h, where the scale / shows the quantity. The
cock serves to discharge the glass tube or vessel h into a vessel placed under it.
The cover a of the tank has a bracket b with an opening which can be locked
over the handle of the pump. To bring the cover in its right position over the
collecting funnel B it must be moved first under the head of the pin c in such
manner that the scallop or notch a¹ passes over the head of the other pin c.
The cover is turned till the bracket b can be locked on the handle of the pump.
On the under side of a a small projection or bar r is fixed in the centre, which
catches in a notch of the cock handle e; so by turning the cover a the cock & also
is turned, and therewith the tank closed hermetically.
The perforated plate f serves to retain dirt and dust which may be mixed with
the oil. The modification of the cover a, shown in Figure 5, is used for tanks
provided with the measuring apparatus.
I am aware that prior to this Invention reservoirs for petroleum, lubricating, or
other oils have been made with a pumping mechanism in conjunction with a
measuring apparatus; I therefore do not claim such a combination generally, but
what I do claim and desire to secure by Letters Patent is,
1. The combination in a reservoir for petroleum, lubricating, or other oils of a
collecting funnel B, having a perforated bottom f, with the cock d, substantially as
described and shewn.
2. In a reservoir for petroleum, lubricating, or other oils the combination of the
collecting funnel B with the cover a, having a scallop or notch a', the bracket b
and the two pins c and c¹, substantially as described and shewn.
3. In a reservoir for petroleum, lubricating, or other oils the combination of the
cover a, having a projection ? on the centre of its under side, with the bandle e of
the cock d, substantially as described and shewn.
4. In a reservoir for petroleum, lubricating, or other oils, the combination of the
discharge pipe the larger pipe i, with the measuring tube h, substantially as
described and shewn.
In witness whereof, I, the said Edmund Edwards, have hereunto set my
hand and seal, this 25th day of February, in the year of our Lord 1881.
