IMPROVE- MENTS IN CARDING ENGINES
Year: 1875

page_text: LETTERS PATENT to Robert Taylor Heape, Junior, of Rochdale, in the
County of Lancaster, Manufacturer, for the Invention of "IMPROVE-
MENTS IN CARDING ENGINES."
Scaled the 11th January 1876, and dated the 16th July 1875.
PROVISIONAL SPECIFICATION left by the said Robert Taylor Heape
at the Office of the Commissioners of Patents, with his Petition,
on the 16th July 1875.
I, ROBERT TAYLOR HEAPE, junior, of Rochdale, in the County of
Lancaster, Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN CARDING ENGINES," to be as follows :—
-
My Invention relates chiefly to those carding engines which are used
in the preparation of wool, and by means of which I am enabled to use
a grid beneath the working cylinder for preventing a waste of material.
To accomplish this I place a circular grid beneath the cylinder, and at
the end thereof nearest the doffer I adapt a roller to which rotatory
motion is imparted from any convenient moving part. This roller turns

page_text: upward the fibrous material which would be liable to hang from the
end of the grid and conducts it to the cylinder, or instead of the fixed
grid a creeper with suitable perforations may be used.
In another armancement Inlan n
travelling
creener at any desired
upward the fibrous material which would be liable to hang from the
end of the grid and conducts it to the cylinder, or instead of the fixed
grid a creeper with suitable perforations may be used.
In another arrangement I place a travelling creeper at any desired
angle, and use in conjunction therewith a roller for transferring material 5
which falls thercon back again to the cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Taylor Heape, in the Great Seal Patent
Office on the 15th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
TAYLOR HEAPE, Junior, of Rochdale, in the County of Lancaster,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by ller
Letters Patent, bearing date the Sixteenth day of July, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, er heirs and suc-
cessors, give and grant unto me, the said Robert Taylor Пcape, junior,
Her special license that I, the said Robert Taylor Icape, junior, my
executors, administrators, and assigns, or such others as I, the said
Robert Taylor Heape, junior, my, 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 therein 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 "IMPROVEMENTS IN CARDING ENGINES," upon the
condition (amongst others) that I, the said Robert Taylor Fcape,
junior, my executors or administrators, by an instrument in writing
under my hand and seal, 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 calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Robert Taylor Heape, do hereby
declare the nature of my said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in
and by the following statement and accompanying Drawings (that is to
say).-
My Invention relates chiefly to those carding engines which are used
in the preparation of wool, and by means of which I am cuabled to use
a grid beneath the working cylinder for preventing a waste of material;
or in place of the said grid I use a travelling creeper for effecting the
same object
The application of my Invention may be varied in construction and
arrangement, but in the accompanying Drawing I have shown four of
such arrangements by way of illustration, and which I will now procced
to describe
In Fig 1 a is the working cylinder of a carding engine; b, the licker-
in, and c, the doffer Beneath the cylinder a 1 place a grid d, as shown
by the dotted line, such grid also extending under the licker-ın 6, and
so far the arrangement is not new, such grids having before been applied,
but not so far as I know with success, but according to my Invention I
adapt a roller e revolving in the direction of the arrow, and the effect is
as follows. The dust, together with valuable material, being thrown
upon
the grid the former passes through it, while the material 18
carried forward and presented to the licker-in, which again places it upon
the cylinder; but by this arrangement only the thrown off material is
liable to hang downward from the end of the grid and there become
clogged up. This is prevented by the roller e, which by revolving in
the direction of the arrow turns upward the material and presents it to
the surface of the cylinder. Thus roller e may simply have a plain and
smooth surface.
Fig. 2 represents one arrangement of creeper I employ instead of the
above-mentioned fixed grid. At a is the working cylinder; at 6 the
licker-in, and at c the doffer; at f, g, are two rollers, over which there
passes a creeper h formed as a lattice, and at 2 is a roller covered with
card or other surface which will take up fibies, and running nearly in
contact with the said lattice and with the cylinder a. The dust and
material thrown from the cylinder and doffer fall upon the travelling
creeper h, the former passing through its spaces while the latter is carried
forward until it arrives at the roller, which by its revolution carries it
upward and delivers it to the cylinder a.

page_text: Fig. 3 is a modification of the arrangement shewn at Fig. 2. The
creeper h is still employed, but the roller 2 is dispensed with, that shown
at g taking its place, by which means the surface of the said creeper
conveys the thrown-off material direct to the cylinder.
Fig. 4 shews my Invention applied to a carding engine in which two
cylinders are employed, such cylinders being shewn at a, a¹. At k, l, aro
the usual revolving surfaces which transfer the material from one
cylinder to the other, and at c is the doffer. At h is the creeper carried
by the rollers f, g. The material thrown from the doffer and cylinder is
carried forward until it is presented to the card roller 2, which, as in
Fig. 2, transfers the said material to the cylinder a', and any which may
remain on the creeper or be thrown thereon from the intermediate
doffer / and roller is restored thereto by the roller g, which causes the
lattico to travel close to the surface of the said intermediate doffer. I
have not described how the several parts above referred to are caused to:
revolve, as they may be driven from any moving parts of the machino
by any suitable means, and at such speeds as may be found bcst,
according to the conditions under which they are applied.
Having thus described and ascertained the nature of my said Invention
and the manner in which the same is to be performed, I desire it to be
understood that I claim as secured to me under the above in part recited
Letter Patent and for the purpose above set forth,-
Firstly, in reference to Fig. 1, the use of the fixed grid d and
roller e
Secondly, in reference to Fig. 2, 3, 4, the use of the travelling 2
creeper or grid h, and transferring apparatus conncoted therewith, all
substantially as described.
In witness whereof, I, the said Robert Taylor Icape, junior, have
hereunto set my hand and seal, this Fourteenth day of January,
in the year of our Lord One thousand eight hundred and seventy- 3
SIX.
