IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CLEANING OR REMOVING OIL OR GREASE FROM TIN, TERNE, OR OTHER METAL PLATES OR SHEETS."
Year: 1881

page_text: LETTERS PATENT to Thomas Henry Morgan, of Maes-y-bar, Llansamlet, and
also of the Cambrian Patent Office, Swansea, both in the County of Glamorgan,
for an Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
CLEANING OR REMOVING OIL OR GREASE FROM TIN, TERNE, OR OTHER
METAL PLATES OR SHEETS."
PROVISIONAL SPECIFICATION left by the said Thomas Henry Morgan at
the Office of the Commissioners of Patents on the 1st March 1881.
THOMAS HENRY MORGAN, of Maes-y-bar, Llansamlet, and also of the Cambrian
Patent Office, Swansea, both in the County of Glamorgan. "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR CLEANING OR REMOVING OIL OR GREASE FROM
TIN, TERNE, OR OTHER METAL PLATES OR SHEETS.".
This Invention has for its object the removing of oil or grease from tin, terne, or
other metal plates or sheets in an effective and simple manner.
It consists in a suitable framing divided into compartments or spaces, in each of
which are alternately placed a pair of rolls running in suitable adjustable housings
and a pair of brushes. The top bearings or housings of each pair of rolls or brushes
are mounted in vertical guides, ending near the top so as to be easily removable.
The housings of rolls or brushes can be adjustable by screws acting on springs, or
in any convenient manner.
The rollers are arranged to run at the same rate of speed, but the gearing should
be so proportioned that the brushes rotate, say, from two to three or more times
as fast as the rolls.
I find an advantageous size to make the diameter of the rolls and brushes about
4 inches, but do not bind myself to this.
I cover the top of the framing and fix in it a small hopper with a regulated
opening to supply bran or similar pulverulent material to the first pair of brushes
immediately below it, so that the brushes carry the bran round to absorb the
oleaginous matter on the plate or sheet passing between them. The excess of bran
falls into an outwardly projecting shoot and thence into a pit or receptacle, from

page_text: which it is raised again to the hopper by an Archimedean screw, Jacob's ladder, or
other conveyor for further use.
A similar hopper is placed at the end where the plates or sheets first enter. It
extends closely or rather nearly to a table which closes the mouth and prevents
the bran running out (the sides being constructed of elastic material, such as tin
plate), so that the plate or sheet of metal passes through a body of bran into the
first compartment which has neither rolls nor brushes in it, but a drawer or
receptacle is placed at its bottom to catch any bran passing through. In this
compartment are a pair of hide-covered scrapers to scrape off any adhering bran or
grease.
On the inside of the styles or rails of the framing I place small guides to direct
the plates or sheets from the rolls to the brushes, and from the brushes to the next
pair of rolls, and to prevent the plates or sheets from being being bent and not
passing through. The cleaned plates are delivered by the last pair of rolls.
It is obvious that the mechanical details of my Invention can be greatly varied
without departing from the principle.

1st September 1881.

Patent Office, Swansea, both in the County of Glamorgan. "IMPROVEMENTS IN.
MACHINERY OR APPARATUS FOR CLEANING OR REMOVING OIL OR GREASE FROM
TIN, TERNE, OR OTHER METAL PLATES OR SHEETS."
This Invention has for its object the removing of oil or grease from tin, terne, or
other metal plates or sheets in an effective and simple manner.
It consists in a suitable framing divided into compartments or spaces, in each of
which are alternately or otherwise placed a pair of rolls running in suitable
adjustable housings and a pair of brushes. The top bearings or housings of each
pair of rollers or brushes are mounted in vertical guides ending near the top so as
to be easily removable.
The housings of rollers or brushes can be adjustable by screws acting on springs,
or in any convenient manner.
The rollers are arranged to run at the same rate of speed, but the gearing should
be so proportioned that the brushes rotate, say, from two to three or more times as
fast as the rolls.
I cover the top of the framing and fix in it a small hopper with a regulated
opening to supply bran or similar pulverulent material to the first pair of brushes
immediately below it, so that the brushes carry the bran round to absorb the
oleaginous matter on the plate or sheet passing between them.
The excess of bran falls into an outwardly projecting shoot, and thence into a
pit or receptacle, from which it is again raised to the hopper by an archimedean
screw, Jacob's ladder, or other conveyor, for further use.
A similar hopper is placed at the end where the plates or sheets first enter. It
extends closely or rather nearly to a table which closes the mouth and prevents the
bran running out (the sides being constructed of elastic material such as tin plate),
so that the plate or sheet of metal passes through a body of bran into the first
compartment, which has neither rolls nor brushes in it, but a drawer or receptacle
is placed at its bottom to catch any bran passing through.
In this compartment are a pair of hide covered scrapers to scrape off any
adhering bran or grease.
However, I find it more advantageous to employ one hopper with a double
opening and modified arrangements, as hereafter described.
On the inside of the styles or rails of the framing I place small guides to direct
the plates or sheets from the rolls to the brushes, and from the brushes to the next
pair of rolls, and to prevent the plates or sheets being bent and not passing through.
The cleaned plates are delivered by the last pair of rolls.
It is obvious that the mechanical details of my Invention can be greatly varied
without departing from the principle thereof.
And in order that my Invention may be more clearly understood I will now
proceed to describe the same by reference to the Sheet of Drawings annexed.
I find that five pairs of rolls A, and four of revolving brushes B, are suitable for
the purposes of the machine as represented. I now make the diameter of the
brushes greater than that of the rolls, and so adjust the gearing of the top brush
with the under brush that either of them revolves a little faster than the other, so
that when there happens to be no plate between them they may brush each other,
and thus clean or rub off any adhering matter.
As stated above, I find I can with, advantage employ one hopper C of greater
dimensions, but having two openings D, and thus one arrangement for re-filling (not

page_text: shown in the Drawings) will alone be necessary. Under the first opening D in the
hopper I place a pair of stationary brushes E, E, the back of the upper one being
close to slots or openings or rows of holes F so that the bran or other material may
pass through to the hair. The other brush faces the first, and the plate to be
cleaned in entering the machine passes between them.
I may also place a second pair of brushes G, narrow in section, behind the first
pair of revolving brushes to brush from the plate any adhering matter. before
entering the next pair of rolls, instead of the hide covered scrapers.
A receptacle H is placed under the first pair of brushes to catch the falling bran
or other material, and from this to supply the under brush.
The bran or other material falling from the machine is received in a pit, and
from this the hopper is replenished. In the Drawing the brushes are shown as
rotating only a little faster than the rolls in the opposite direction, but this relative
rate by suitable gearing may be increased. I have not shewn the pit or arrange-
ment for lifting the bran, as such methods of raising are well known.
I, I, represent the guides to direct the plates between the rollers and brushes.
J, J, are the adjusting screws.
K, the main driving wheel.
L, L, friction pulleys or gear wheels driving the rolls and brushes.
Having now described the nature of my Invention, and the manner of performing
the same, I would have it understood that what I claim is,―
The improved apparatus for cleaning or removing oil or grease from tin, terne,
or other metal plates or sheets, consisting of the combination of rolls and brushes
and arrangements for supplying bran or other pulverulent material to, and devices
for guiding the plates or sheets, as and for purposes described.
In witness whereof, I, the said Thomas Henry Morgan, have hereunto set
my hand and seal, this 29th day of August, in the year of our Lord One
thousand eight hundred and eighty one.
