IMPROVEMENTS IN CARDING ENGINES
Year: 1874

page_text: LETTERS PATENT to Jolin Midgley, of Halifax, in the County of York,
Woollen Spinner, for the Invention of "IMPROVEMENTS IN CARDING
ENGINES."
Sealed the 8th June 1875, and dated the 11th December 1874.
PROVISIONAL SPECIFICATION left by the said John Midgley at the
Office of the Commissioners of Patents, with his Petition, on the
11th December 1874.
I, JOHN MIDGLEY, of Halifax, in the County of York, Woollen Spinner,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CARDING ENGINES," to be as follows :-
"
This Invention relates to that class of carding engines which are
provided at the delivery end with one or more creepers" or endless
aprons, upon one of which the wool or other fibre is laid in layers for
the purpose of forming a lap or roll, being pressed upon the said creeper
by one, two, or more rollers or cylinders (usually of tin), and my In-
vention consists in the use of a cleaning apparatus for such rollers or

page_text: cylinders, which is constructed and applied as follows:-On the top of
each roller is placed a piece of wood or other suitable substance extending
from end to end of the roller, and hollowed or made concave to about.
the same radius as the roller, the width being sufficient to cover about
one-fifth of the circumference. The concave side of the board is faced
with cloth, and each end thereof is provided with a pin which fits in a
slot in each of the roller bearers so arranged that the said board can be
lifted out and replaced when the machine is at work. When the rollers.
are used in pairs the boards may be hinged together, whereby the
removal and replacement is facilitated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Midgley in the Great Seal Patent Office on
the 11th June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MIDGLEY, of Halifax, in the County of York, Woollon Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of December, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did; for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Midgley, Her special
licence that I, the said John Midgley, my executors; administrators,
and assigns, or such others as I, the said John Midgley, 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
John Midgley, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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

page_text: 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 John Midgley, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
..following statement, that is to say :—
This Invention relates to that class of carding engines which are -
provided at the delivery end with one or more creepers or endless aprons,
upon one of which the wool or other fibre is laid in layers for the purpose
of forming a lap or roll, being pressed upon the said creeper by one, two,
or more rollers or cylinders (usually of tin), and my Invention consists
in the use of a cleaning apparatus for such rollers or cylinders, which is
constructed and applied as follows:-On the top of each roller is placed
a piece of wood or other suitable substance extending from end to end
of the roller, and hollowed or made concave to about the same radius as
the roller, the width being sufficient to cover about one-fifth of the
circumference. The concave side of the board is faced with cloth, and
cach end thereof is provided with a pin which fits in a slot in each of
the roller bearers, so arranged that the said board can be lifted out and
replaced when the machine is at work. When the rollers are used in
pairs the boards may be hinged together, whereby the removal and
replacement is facilitated.
'
In order that this Invention may be fully understood. I herein give
reference to an accompanying Sheet of Drawings marked with Figures
and letters of reference.
Figs. 1 and 2 shew my cleaning apparatus as applied to a Marsden &
Blamire's machine. A are the rollers for pressing the wool or fibre
upon the endless sheet after being delivered thereto by the rollers A¹;
B and C are pieces of wood hinged together at c, each piece being
hollowed out or made concave so as to cover a portion of the diameter of
the roller upon which it rests. The concave side of each board is faced
with cloth. The pieces hinged together are placed upon the rollers,
and are kept in position by means of pins D, one of which is fixed to
each end of one of each pair of cleaners, and which pins are placed in
slots in the plates E attached to the framework of the carriage.
Fig. 3 shews the application of my apparatus to a Horsfall's machine.
F are the cleaners, which are kept in position upon the roller G by

page_text: loops g passing over the rods h, which extend across the machine. The
endless sheets H may be cleaned by similar means, J being the cleaners
faced with cloth on the portions in contact with the sheets. They are
kept in position by square studs ; placed in slots in the brackets K and
fastened by the pins or screws L.
From the two examples here given it will be seen that the apparatus
may be easily adapted to all machines where it is required, or in which
the sliver is likely to be damaged or broken by adhering to the rollers,
which generally occurs when the rollers are allowed to become covered
with dirt or grease.
I claim as my Invention the application and use of cleaning apparatus,
substantially as herein shewn and described.
In witness whereof, I, the said John Midgley, have hereunto set my
hand and seal, this Ninth day of June, in the year of our Lord
One thousand eight hundred and seventy-five.
Witness,
J. W. TASKER,
Patent Agent,
Halifax.
