Year: 1882

page_text: LETTERS PATENT to John Robinson of Bradford in the County of York
for an invention of "IMPROVEMENTS IN THE CONSTRUCTION OF VESSELS FOR
CONTAINING OIL OR OTHER LIQUIDS."
PROVISIONAL SPECIFICATION left by the said John Robinson at the Office
of the Commissioners of Patents on the 27th April 1882.
"IMPROVEMENTS IN THE
JOHN ROBINSON of Bradford in the County of York
CONSTRUCTION OF VESSELS FOR CONTAINING OIL OR OTHER LIQUIDS."
This invention has reference to cans or vessels for containing and storing oil the
principle object of my improvements being to construct and arrange such cans so
that the oil can be kept clean and easily withdrawn therefroin. For this purpose
I employ a vessel in which is placed a pump the bottom end being connected to an
elbow pipe issuing from the top of the vessel and out of which the oil flows when
the pump is operated. In the top of the vessel is formed a concave dish provided
with an air pipe for admitting air thereto and a sieve is placed at the bottom of
the concavo dish for receiving the droppings from the delivery pipe. I also
employ a filter which I place in the vessel for cleaning and purifying the oil and a
plug or tap is placed at the bottom of the vessel to let out the dirt and sediment
which from time to time accumulates.
In connection with the delivery pipe I attach a small vessel having marks or
pointers thereon so that the quantity of oil withdrawn from the vessel may be
measured.

JOHN ROBINSON of Bradford in the County of York. "IMPROVEMENTS IN THE
CONSTRUCTION OF VESSELS FOR CONTAINING OIL OR OTHER LIQUID."
This Invention has reference to cans or vessels for containing and storing oil, tho
principal object of my Improvements being to construct and arrange such cans so
that the oil can be kept clean and casily withdrawn therefrom. For this purpose
I employ a vessel in which is placed a pump, the bottom end being connected to an
elbow pipe issuing from the top of the vessel and out of which the oil flows when
the pump is operated. In the top of the vessel is formed a concave dish provided
with an air pipe for admitting air thereto, and a scive is placed at the bottom of
the concave dish for receiving the droppings from the delivery pipe. I also
employ a filter which I place-in-the-vessel-for-cleaning and purifying the oil, and a
plug or tap is placed at the bottom of the vessel to let out the dirt.and sediment
which from time to time accumulates.
In order that my Invention may be better understood, I herein give reference to
the accompanying sheet of Drawings wherein Fig. 1 is elevation, Fig. 2 section, and
Fig. 3. plan view of apparatus constructed according to my Invention. A is a
vessel having a bottom B and top C the latter of which is capable of being-removed
when required. D is a pump which when operated lifts and forces the liquid up
the pipe E and out at the orifice F, falling into a reeptacle placed to receive it.
The top of the vessel is concaved-or-dished-and-perforated as shewn by the letter a,
so that the oil which may drop from the outlet or which overflows on the
receptacle being filled with oil; will fall into the dished top and so get back into
the vessel. G and H are scives employed for the purpose of cleaning the oil as it
passes through them. The bottom of the vessel is provided with a plug I so as to
Iet out the dirt and sediment which may accumulate therein. The pipe E is
connected to a solid bar J so that they form a convenient handle for carrying the
vessel about.
When this apparatus is not in use, it can be made secure so that no one can
remove the oil until allowed to do so. A lid K is placed over the concave dish and
secured thereon by the plug L which is screwed into the short pipe M fastoned to
the dish. A loop N is also employed so that a pad lock or other fastener connected
thereto and to the loop P formed on the top of the pump rod entirely prevents the
pump being operated until the lock or fastener is removed.
In order to ascertain the quantity of oil in the vessel, a tube S (after the manner
of a water gauge employed in steam boilers) is placed in front thereof, which may
be covered by a door and kept under lock and key.
When the vessel is used for petroleum or other evaporating liquid, it is necessary
for it to be air tight, the holes in the concave dish are therefore dispensed withi
and a plug R (see Fig. 4) is employed fitting into an opening formed in the dish, and
in order to secure the plug therein one or more grooves bure made in it which fit
into pins or studs projecting from the sides of the opening in the dish or vice-versa
so that when the plug is turned around, it cannot be lifted therefrom. The loop is
afterwards fastened to the pump rod by pad lock as previously explained.
Having now shewn and described my Invention and the manner of carrying the
same into effect, I would have it understood that I do not confine myself to the
exact details herein shewn and described, but what I claim as my Invention is-
Firstly. The use and employment of the two soives G and H for cleaning the oil,
passing into the vessel.

page_text: Secondly. The employment of the plug I so as to remove the dirt and sediment
from the vessel.
Thirdly. The connection of the pipe E with the bar J so as to form a handle for
carrying the vessel as shewn described.
Fourthly. The means herein shewn and described for securing the lid K to the
concave dish.
Fifthly. The use of the plug R for making the vessel airtight when containing
petroleum or other evaporating liquid.
In witness whereof, I the said John Robinson have hereunto set my hand and
seal this twenty fifth day of October in the year of our Lord one thousand
eight hundred and eighty two.
JOHN ROBINSON. (LS.)
