CERTAIN IMPROVEMENTS IN CARDING ENGINES."
Year: 1860

page_text: LETTERS PATENT to John Lowden, in the Township of Royton, in the
County of Lancaster, Carder, and Robert Buckley, in the Township of
Royton, in the County of Lancaster, Manager, for the Invention of
"CERTAIN IMPROVEMENTS IN CARDING ENGINES."
PROVISIONAL SPECIFICATION left by the said John Lowden and Robert
Buckley at the Office of the Commissioners of Patents, with his Petition
on the 3rd December 1860.
We, JOHN LOWDEN, in the Township of Royton, in the County of Lancaster,
Carder, and ROBERT BUCKLEY, in the Township of Royton, in the County of
Lancaster, Manager, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN CARDING ENGINES," to be as follows:-
Our invention consists of a novel arrangement of apparatus for separating or
extracting dust, dirt, moats, or other foreign substances from the cotton, cotton
waste, or other fibrous materials on the roller commonly termed the taker-in
roller of carding engines, and also of a peculiar method of preventing the said
dust, dirt, moats, or other foreign substances dropping from the taker-in roller
becoming mixed with the cotton fly or waste thrown off by the main cylinder of
the said carding engine, thus materially increasing the value of the said cotton
fly or waste, and considerably decreasing the wear and tear of the cards on the
main cylinder. We effect this by fixing underneath the taker-in roller a grid
or grating, consisting of a number of bars or round angular or beviled rods

page_text: running parallel with and from end to end of the said taker-in roller; the bars
or rods are made of iron, steel, brass, wood, or other suitable materials, and
are placed at equal distances from each other, and vary in number from six to
forty bars or rods to a grid or grating, and further, the said bars or rods being
either stationary or actuated by connection with some moving part or parts of
the said carding engine that would give the required motion, the said grid or
grating is required to be placed as close to as possible (without, however, touch-
ing) the cards of the said taker-in roller, and held in such position by suitable
supports, fixed or moveable, connected to the framework of the said carding
engine.
Attached to the before-named grid or grating, and rising upwards and be-
tween and as near to the said taker-in roller and main cylinder as possible,
without absolutely touching, is fixed a knife, plate, or bar made of iron, steel,
brass, tin, wood, or other suitable material, and hollowed or curved on one side.
to correspond with the curve of the taker-in roller, and on the other side to the
curve of the main cylinder, in connection with which said knife, plate, or bar,
and projecting downwards the whole width of the carding engine, is a metal
partition fixed by suitable brackets to the floor or framework of the carding
engine, having for its object the separation of the dust, dirt, moats, or other
foreign substances that may fall from the said taker-in roller, from the cotton
fly or waste thrown off by the main cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Lowden and Robert Buckley in the Great Seal Patent
Office on the 3rd June 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
LOWDEN, in the Township of Royton, in the County of Lancaster, Carder, and
ROBERT BUCKLEY, in the Township of Royton, in the County of Lancaster,
Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Third day of December, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of. Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John Lowden and Robert Buckley, Her especial license that we, the said John
Lowden and Robert Buckley, our executors, administrators, and assigns, or
such others as we, the said John Lowden and Robert Buckley, our executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therin

page_text: expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "CERTAIN IMPROVEMENTS IN CARDING
ENGINES," upon the condition (amongst others) that we, the said John
Lowden and Robert Buckley, by an instrument in writing under our hands
and seals, or under the hand and seal of one of us, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calender month next and immediately after the date
of the said Royal Letters Patent.
NOW KNOW YE, that we, the said John Lowden and Robert Buckley,
do hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawing, that is to say:-
Our Invention consists of an arrangement of apparátus for abstracting dust,
dirt, moats, or other foreign substances from the cotton, cotton waste, or other
fibrous material on the roller, commonly termed the taker-in or licker-in, and
also from the main cylinder of carding engines.
These improvements are effected by fixing underneath, and as near as may
be convenient without absolutely touching the cards of the taker-in or licker-in
roller, a grid or grating, consisting of a number of bars or rods, round, angular,
or bevilled, having plain or toothed edges, as may be found desirable, and
placed parallel with and extending from end to end, and arranged in a frame
or otherwise, corresponding in curve with the taker-in or licker-in roller. The
bars or rods forming the grid or grating are required to be placed in the frame
at equal distances from each other, or otherwise, as may be found desirable, and
with their approximate edges at a distance of from one-eighth to half of an
inch or more apart. In connection with the grid or grating we have a box of
metal or other suitable material (of any desirable shape), having for its object
the collection of the dust, dirt, moats, or other foreign substances that may fall
between the bars or rods. For the purpose of releasing such accumulations of
dust, dirt, and moats in the box, we have on one side a door which is opened
by means of a double lever with balance weight, actuated by contact with a
stud fixed on one of the feed roller pullies or wheels at each revolution, and is
closed by the weight of the balance on the lever. The dust, dirt, and moats or
other foreign material falling from the box are kept separate from the fly or
waste thrown off by the main cylinder by means of a metal partition connected
with the upper portion of the grid or grating, and descending diagonally to the
back of the carding engine. To the grid or grating is also attached. a knife,

page_text: plate, or bar of metal or other suitable material rising upwards and between
and near as possible to the taker-in or licker-in roller and the main cylinder,
one side of which knife, plate, or bar is formed to correspond with the curve of
the taker-in or licker-in roller, whilst the other side corresponds with the curve
of the main cylinder, the object of which is to obstruct any dust, dirt, or moats
or other foreign substances that may have passed the grid or grating.
:
But in order that our improvements may be better understood and explained
in detail, we have hereunto attached a Sheet of Drawings, having on the several
Figures the same letters of reference marked on similar parts of the apparatus
or machinery.
Figure 1 represents a vertical side elevation of a portion of a carding engine
having our improvements attached. Figure 2 is an enlarged view of the same.
Figure 3 is a plan of the grid or grating on an enlarged scale. Figure 4 is a
section through A, B, as shewn in Figure 3. Figure 5 is an end elevation of
the grid or grating, with the dust or dirt box and apparatus for opening the
door of the same. Figure 6 is a section through C, D, as shewn in Figure 4.
Figure 1 a is the taker-in or licker-in roller, 6 is the main cylinder, c
is the grid or grating, d is the lower portion of the box, e is the door
connected with the box, f is a stud fixed on the wheel g, which at each
revolution acts upon the double lever h, h, and raising the same causes the
door e to open (the lever h, h, being fixed on a stud i and connected with
the door), the other arm of the lever h, h, having on it a weight k suffi-
ciently heavy to close the door e and keep it shut except when acted upon by
the stud on the wheel g; is the partition separating the dust, dirt,
moats, and other foreign materials that fall through the grid or grating c and
out of the box d from the fly or waste thrown off by the main cylinder.
It will be observed that as the taker-in or licker-in roller revolves, any
foreign material, such as dust, dirt, and moats that may be on the surface of
the cards coming in contact with the bars or rods m forming the grid or
grating will be obstructed (inasmuch as it is requisite to place the grid or
grating as close as possible to the cards of the said taker-in or licker-in roller
without absolutely touching the same) the materials so abstracted will then
pass between the bars or rods m shewn in Figures 2, 3, 4, & 6, and into the
box d, Figures 1, 2, 5, & 6 immediately below the grid or grating. Forming
a part of (or otherwise connected with) the grid or grating is a knife, plate, or
bar n, as shewn in the enlarged Figures 5 & 6, the object of which is to
obstruct the passage on the main cylinder of any materials, such as moats
or other foreign substances that may have escaped contact with the bars or
rods forming the grid or grating.

page_text: It may in some cases be advantageous to have the edge of the knife, plate,
or bar n made in a toothed form, but we do not confine ourselves exclusively
to this or other formation.
Figure 2 is an enlarged view of Figure 1, more clearly shewing the position
of the grid or grating c and box d with the method we here employ to
open the door e.
In Figure 3 is shewn the arrangement of the bars or rods m forming the
grid or grating c, which are placed parallel with each other from one-eighth
to half of an inch or more apart, as may be found desirable.
Figure 4 is a section of the grid or grating c, in which is shewn plain and
toothed bars or rods; the edges of such bars or rods that are of toothed forma-
tion point in an opposite direction to that in which the taker-in or licker-in
roller revolves.
Figure 5 gives an end view of the grid or grating c with the box d and
door e partly opened by the apparatus f, g, and h, h, (also shewn in
Figures 1 and 2) connected therewith.
Figure 6 is a section from C to D in Figure 4 of the grid or grating c in
which is shewn the position of the bars or rods m in the frame.
Having thus particularly described and ascertained the nature of our
Invention, and in what manner the same is to be performed, we desire it to be
distinctly understood that we do not confine ourselves to the precise arrange-
ment shewn and described, as the same may be varied without departing from
the nature of our Invention, but we claim as our Invention the peculiar forma-
tion of the grid or grating in combination with the dust or dirt box and the
knife, plate, or bar, as herein shewn and described.
In witness whereof, I, the said Robert Buckley, for and on behalf of
myself and the said John Lowden, have hereunto set my hand and
seal, this First day of June, in the year of our Lord One thousand
eight hundred and sixty-one.
Witness,
