COMPLETE SPECIFICATION.
An Improved Apparatus for Purifying Oil and Separating New Oil
from Drippings, applicable also as an Oil Tank.
We, EMIL NOPPEL, Machinist of 803 Callowhill Street Philadelphia, State of
Pennsylvania BRUNO GROSCHE Merchant and THEODORE EDWARD TACK
Oil Producer both of 136 Liberty Street, New York City, all in the United States
of America, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
My invention consists of improvements in apparatus for purifying oil which has
been used in lubricating, and separating new oil from drippings, the same embodying
a tank, chambers therein, heating, blow-off and cleansing devices, and means for
purifying or refining new oil, without having the same pass through the drippings
or old oil in the tank, or agitating the sediment therein, the construction of parts
being hereinafter fully set forth.
The accompanying drawing represents a vertical section of an apparatus embody-
ing my invention.
A designates a tank within which at the upper end thereof is supported a funnel
or reservoir B, the latter having therein a vertical diaphragm C, dividing the
reservoir into two compartments D E. The compartment D is provided with a
pipe F, the same depending from the bottom thereof, the chamber E having a
pipe G which likewise depends from the bottom thereof.
Rising from the bottom of the tank A, is a cylinder H. over which is an inverted
cylinder J, the same thus being closed at top and open at bottom.
Within the cylinder H is a cylinder K, which is closed at bottom and open at
top, and passes through the top of the cylinder J it being noticed that portion of
the pipe enters the cylinder K, and portion of the pipe G passes through the top
of the cylinder J, and enters the cylinder H, it being also noticed that the pipe G
is.secured to the top of the cylinder J, and the cylinder K is also secured to said
top; whereby when the reservoir B is removed, the cylinders J, K may be removed
with the same, and said parts may be afterwards readily restored to position.
Within the reservoir B is a funnel L, which is provided with a pipe M, the outlet
portion of said funnel passing through the bottom of said reservoir where the pipe M
is attached, said pipe passing into the tank A, and having its lower end within the
cylinder J.
At the base of the cylinder..) is a chamber N, the top wall of which is provided
with nozzles. P. Within the cylinder H is a pipe Q which freely encircles the
cylinder K, and pipe G, said pipe Q having branches R and S at opposite ends for
the passage of steam into and therethrough, for the purpose of heating the contents
of the cylinder H, and of the cylinder K, if so desired.
T designates a pipe which passes through the tank A and cylinder. H, the portion
within said tank and cylinder being perforated, whereby steam may be admitted
into said tank and cylinder for blow-off purposes.

In the bottom of the cylinder H is an outlet U, which is closed by a cap V, and
the lower portion of the tank A is provided with cocks W X the cock W opening
into said tank and the cock X having a branch X' which passes through the tank :
into the cylinder H.

The operation is as follows-Oil to be purified and. refined is poured into the
compartment E, and after passing through the pipe G, enters the cylinder H, and :
fills. the same to overflowing, said cylinder being surrounded by water into which
.

page_text: the sides of the cylinder J and the chamber N dip it being seen that the oil then
enters the water between the two cylinders J, H, and descends through the water to
the chamber N, where it escapes through the nozzles P, and rises through the water
outside of the chamber J, it having been washed in its passage through the water.
The sediment in the chamber H settles at the bottom thereof, from whence it may
be withdrawn through the discharge U, and the sediment in the tank may be
discharged by the cock W, said cock also providing means for clearing the tank
entirely of its contents when so desired, while the cock X may be employed for
discharging the cylinder H entirely of its contents.
When it is desired to heat the contents of the cylinder H, to assist in the
purifying and refining operation, steam is admitted to the coil Q, and the heat of
the contents of the cylinder H may be utilized to heat the cylinder K.
Should the supply in the tank of the purified oil be reduced by reason of its being
drawn off, new oil may be poured into the compartment D, it is directed into the
cylinder K by means of the pipe F, and escapes at the bottom of the latter into said
cylinder which contains a quantity of water or purifying or refining material,
through which the oil rises and in which it is washed, the oil then overflowing at
the top of the cylinders K into the tank A, from whence it may be withdrawn it
being noticed that the new oil has not entered the cylinders H J or passed through
the dripping, and there is consequently no disturbance or agitation of the sediment
in said cylinder or in the tank, it being noticed that the apparatus thus serves both
as an oil tank and a purifier.
The bottom of the cylinder K is closed by a cap or plug K¹ whereby any
sediment therein may be removed when the cylinder is removed from the tank.
The pipe M may be employed to remove gas from the cylinders H and J, and to
replenish the tank with water.
In speaking of the cylinders, I do not wish to limit myself to the shape, as
such as they are meant to include any vessel or chamber of the same capabilities.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1. A tank having the cylinder H therein, the same being closed at bottom and
open at top, the cylinder K in said cylinder J, the supply pipe F entering said
cylinder K, the inverted cylinder J over said cylinder H, and the outlet U at the
bottom of the vessel said parts being combined substantially as described.
2. The vessel H closed at bottom and open at top, in combination with the tank A
which receives said vessel H, the inverted vessel Jover said vessel H the heating
pipe in said vessel H and the blow-off pipe T entering said tank and vessel H
substantially as set forth.
3. An apparatus for the purpose set forth having a receiving funnel with separate
compartments therein, and separate purifying vessels connected therewith, substan-
tially as described.
4. An apparatus for the purpose set forth, having a tank, a vessel therein, and an
auxiliary vessel inclosed in the other vessel, the vessels having separate supply pipes
connected therewith, substantially as described.
5th. A tank having the vessel H with a supply pipe, and the inverted vessel J
over said vessel H in combination with the vessel K which is located within the
vessels J, H but not directly in communication therewith, and a supply pipe
connected with said vessel K independent of the supply pipe of the vessel H
substantially as set forth.
6. A tank, a vessel therein, a supply pipe connected with said vessel, and an
inverted vessel over the first named vessel, in combination with the pipe M which
