IMPROVEMENTS IN CARDING ENGINES
Year: 1874

page_text: LETTERS PATENT to Robert Hudson, of Gildersome, near Leeds, in
the County of York, for the Invention of "IMPROVEMENTS IN CARDING
ENGINES."
Sealed the 7th May 1875, and dated the 12th November 1874.
PROVISIONAL SPECIFICATION left by the said Robert Hudson at the
Office of the Commissioners of Patents, with his Petition, on the
12th November 1874.
I, ROBERT HUDSON, of Gildersome, near Leeds, in the County of
York, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN CARDING ENGINES," to be as follows:-
My Invention relates to improvements in what are called "first feeds "
for carding engines, and consists in dispensing with the hook, wheel,
lever, and other gearing at present used for raising and lowering the
"scale pan," and substituting in lieu thereof a cam fixed on the "feed
roller" shaft actuating a lever and rod with catch to raise and lower the
weighing scale pan. This arrangement ensures the same length of
feed sheet being presented every time the scale pan is raised or
lowered.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Hudson in the Great Seal Patent Office on
the 12th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
HUDSON, of Gildersome, near Leeds, in the County of York, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of November, 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 successors, give and
grant unto me, the said Robert Hudson, Her special licence that I, the
said Robert Hudson, my executors, administrators, and assigns, or such
others as I, the said Robert Hudson, 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 Hudson, 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 imme-
diately after the date of the said Letters Patent.
:
NOW KNOW YE, that I, the said Robert Hudson, do hereby declare
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings
and to the letters of reference marked thereon, that is to say :-
My Invention relates to improvements in what are called first feeds
for carding engines, and consists in dispensing with the hook, wheel,
lever, and other gearing at present used for raising and lowering the
"scale pan," and substituting in lieu thereof a cam fixed on the "feed
roller" shaft actuating a lever and rod with catcli to raise and lower
the weighing scale pan. This arrangement ensures the same length of

page_text: feed sheet being presented every time the scale pan is raised or
lowered.
And in order that this Invention may be more fully described and
ascertained, I will now proceed to describe the same with reference to
the accompanying Drawing, which represents machinery constructed in
accordance therewith.
My improvements are fixed or attached to the framework of the
hopper K of the carding engines of ordinary construction, as shewn at I.
The wool scale pan L in the position shewn on the Drawing has just
been emptied and raised to receive the "weigh" of wool, and it will be
seen that the catch A projects from the vertical rod B in such a manner
as to support the wool scale pan lever O, retain it in its position until
the cam as it revolves brings the part D under the runner E on the
lever M, when the catch A will descend to the position shewn in dotted
lines at F, thus leaving the wool scale pan L and lever C at liberty to
fall with its weigh of wool the same distance the catch A has fallen,
which is intended to represent the distance required to knock off the
ordinary wool feeding motion, and to prevent any more wool falling into
the pan. The cam then prevents the wool scale pan lever C and parts
connected therewith from falling further until the part H reaches the
runner E, when the rod B and catch A will fall to the position shewn in
dotted lines at I, thus allowing the wool scale to fall and empty its
contents on the feed sheet J, after which the onward course of the cam
again forces up the wool scale pan lever C by means of the catch A to
its original position ready to receive the next weigh of wool.
I wish it to be understood that I do not confine myself to the precise
details as above described, but what I claim to be new is, the improved
method of and means for raising and lowering the wool scale pan, sub-
stantially in the manner described.
In witness whereof, I, the said Robert Hudson, have hereunto set
my hand and seal, this Eleventh day of May, in the year of our
Lord One thousand eight bundred and seventy-five
.
