COMPLETE SPECIFICATION.
A New or Improved Apparatus for Treating Substances Containing
Fats and Oils.
1, WILLIAM OSCAR ROBBINS, Manufacturer, of No. 441 East 83rd Street, of
the City of New York, in the County of New York, State of New York, 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 :-
The object of my invention is to provide an apparatus for extracting the grease
fat oils etc. from wool cotton seed linseed olives and other substances containing such
grease fat or oils.
In the accompanying drawings illustrating my invention
Fig. 1 is a side elevation of my improved apparatus-parts being broken out and
others shown in section.
Fig. 2 is an end view of the treating cylinder the same being shown open.
The treating cylinder A which can be made of any suitable length or diameter is
provided at each end with a gate B that can be closed hermetically and said
cylinder contains tracks B' on which one or more cars C may be run into the
cylinder.
The body C of the car C is made cylindrical of wire netting and of such size
that it fits snugly in the cylinder but easily be run in and out of the same.
The car body C₁ is provided in its top with a recess D extending the entire
length of the car and extending down in said body to about half the height of the
same.
Between the tracks B' a series of steam pipes b are arranged which are connected
with the pipes for the purpose of conducting steam into and through the
pipes b.
The bottom part of the treating cylinder A is connected by a pipe E' with
a distilling apparatus E which in turn is connected by a dome or gooseneck E²
with a condensing coil F or like contrivance in a condensing vat F'.
A steam pipe e in the bottom of the distilling apparatus serves for heating the
liquid to be distilled.
The bottom of the distilling apparatus is connected by a pipe G' with the
receiver G for the fat grease or oil.
A receptacle or tank H for compressed air is connected by the pipe H¹ with the
air compressor J of any approved construction and said compressed air receptacle
or tank H is connected by the pipe I with one end of a perforated pipe K arranged
longitudinally in the treating cylinder A at such an elevation that when a car Čis
run into the cylinder the said pipe K is at the bottom of the longitudinal recess D
in the top of the car body.
The opposite end of the pipe K is connected by a pipe L having a suitable cock
with the gasoline tank M located above the treating cylinder A.
The lower end of the condensing coil F is connected by a pipe with the gasoline
receptacle N from which a pipe O conducts the gasoline to a receptacle P. From
the latter the gasoline is pumped by means of the pump R into the gasoline
tank M.
The operation is as follows:-
The wool cotton seed olives linseed or other material to be treated is suitably
packed in the cars C and the same are run into the treating cylinder A the gates B
of which ow then closed hermetically.

page_text: Then gasoline or benzine or any other suitable hydro-carbon solvent is admitted
into the treating cylinder from the tank M by means of the perforated pipe K.
As the said pipe is located about centrally in the contents of the car the said
solvent is rapidly absorbed and taken up by the contents of the car and distributed
uniformly so as to act on a great quantity of the material at once.
Steam is then admitted into the pipes b for heating the solvent in the cylinder A
and creating a pressure in the treating cylinder A.
The contents of the cars is subjected to the action of the solvent for about
20 minutes more or less according to the nature of the substance to be treated and
then the connection between the treating cylinder and the distilling apparatus
is opened to permit the pressure in the treating cylinder to force the solvent and
the fat grease or oil that the same has taken up into the distilling apparatus E.
Steam is still admitted into the pipes in the treating cylinder for a short time and
then steam is shut off and compressed air is admitted into the treating cylinder for
the purpose of forcing out all particles of the solvent and thoroughly drying the
wool or other substance under treatment.
The solvent containing absorbed fats or oils is distilled in the distilling
apparatus E and the vapors are condensed in the condensing coil F the fat or oil
remaining in the distilling apparatus from which it is drawn through the pipe G¹
into the fat receiver G.
The condensed solvent passes from the condensing coil into the receptacle N runs
from the same through the pipe O into the receptacle P and is pumped from the
same into the tank M to be used again and so on.
After all the solvent has been driven out of the treating cylinder and all pipes
leading to the cylinder closed to prevent the loss of solvent and compressed air the
cylinder is opened and the cars run out to be discharged and to receive a fresh
charge of material to be treated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An apparatus for extracting fats and oils from materials containing them
composed of a treating cylinder for receiving the material to be treated by means
of solvents that take up the fats and oils a perforated pipe extending the length of
said cylinder at about half the height of the same and connected with means for
conducting solvents or air under pressure into said pipe a car having a body for
receiving the material to be treated which car body fits within the treating cylinder
and is provided in its top with a vertical recess the bottom of which is slightly
below the perforated pipe in the treating cylinder and which recess extends the
entire length of car body substantially as herein set forth.
