page_text: LETTERS PATENT to Thomas Wilkes Lord, of Leeds, in the County of
York, Consulting Machinist and General Commission Agent, for the
Invention of "A CERTAIN IMPROVEMENT IN MACHINERY FOR CARDING FLAX,
Tow, AND OTHER FIBROUS SUBSTANCES.'
PROVISIONAL SPECIFICATION left by the said Thomas Wilks Lord
at the Office of the Commissioners of Patents, with his Petition, on the
16th June 1857.
I, THOMAS WILKES LORD, of Leeds, in the County of York, Consulting
Machinist and General Commission Agent, do hereby declare the nature of
the Invention for "A CERTAIN IMPROVEMENT IN MACHINERY FOR CARDING FLAX,
TOW, AND OTHER FIBROUS SUBSTANCES," to be as follows:-
My improvement in machinery for carding flax, tow, or other fibrous
substances consists in the application of a cage or casing, formed of bars or
rods, below the workers and strippers of the lower half of the carding cylinders,
and following the contour of the workers, strippers, and cylinder at a suitable
distance therefrom, so as to allow the dust and shive to pass through the
casing, but retaining the fibrous particles.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Wilks Lörd in the Great Seal Patent Office on
the 15th December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WILKS LORD (by error in the Provisional Specification and Papers applying
for the Letters Patent, and in the said Letters Patent herein-after recited,
spelt Thomas Wilkes Lord), of Leeds, in the County of York, Consulting
Machinist and General Commission Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of June, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year. of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Wilks Lord, Her special licence that I, the said Thomas
Wilks Lord, my executors, administrators, and assigns, or such others as
I, the said Thomas Wilks Lord, 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 "A
CERTAIN IMPROVEMENT IN MACHINERY FOR CARDING FLAX, Tow, AND OTHER FIBROUS
"SUBSTANCES," upon the condition (amongst others) that I, the said Thomas
Wilks Lord, 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 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 Thomas Wilks Lord, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
My improvement in machinery for carding flax, tow, and other fibrous
substances consists in the application of a cage or grating, formed of bars or
rods of wood, iron, zinc, or any other suitable material, in front of and below
the workers or strippers, covering a portion of the cylinder, as shewn in the
Drawings.
Figure 1 represents a side or end view of the circular card and the grating
and Figure 2 a back view of the same. a is the main cylinder, and b, b, the

page_text: rods composing the cage or grating. These rods are attached to side plates c, c,
which are perforated to the sweep or contour of the main cylinder a, and of
the workers d, d, and the strippers e, e, but at suitable distances from them,
that is to say, the grating is placed as near as possible to the main cylinder a,
and to the strippers e, e, and to the workers when they do not take the fibre
round with them; but the distance from the workers that take the fibre round
with them is regulated by the length of the fibre. ff. are the doffing
cylinders; and g, g, are the feed rollers; h is a stay to support the rods in the
middle.
Having thus described the nature of my Invention, and the manner of
carrying the same into effect, I claim in relation thereto the form and position
of the cage or grating, as herein-before described, as applied to carding
cylinders, which prevents the material from falling, but allows the dust and
shive to fall, carrying forward the fibre which is valuable.
In witness whereof, I, the said Thomas Wilks Lord, have hereunto set
my hand and seal, this Seventh day of December, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
ERNEST CANNISSIE.
T. W. LORD. (L.S.)
