Year: 1875

page_text: LETTERS PATENT to Joseph Jefferson, Coinclius Jefferson, Lazarus
Jefferson, and Mordecai Jefferson, all of Bradford, in the County of
York, Machine Makers and Iron and Brass Founders, for the
Invention of "IMPROVEMENTS IN MACHINERY FOR WASHING WOOL AND
OTHER FIBRES."
Sealed the 18th January 1876, and dated the 20th July 1875.
PROVISIONAL SPECIFICATION left by the said Joseph Jefferson,
Cornelius Jefferson, Lazarus Jefferson, and Mordecai Jefferson at
the Office of the Commissioners of Patents, with their Petition,
on the 20th July 1875
WC, JOSEPH JEFFERSON, CORNELIUS JEFFERSON, LAZARUS JEFFERSON,
and MORDECAI Jefferson, all of Bradford, in the County of York,
Machine Makers and Iron and Brass Founders, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
WASHING WOOL AND OTHER FIBRES," to be as follows.―
This Invention relates to improvements in machinery for purpose
aforesaid, whereby certain parts of the machine as heretofore constructed

page_text: are dispensed with, and the wool is delivered to the squeezing rollers
regularly and in even quantity
We dispense with the porcupine "lifting roller" and employ an
endless sheet of lags working over guide rollers, and so arranged that
the "fork" nearest the squeezing rollers on its forward movement pass
over a portion of the endless sheet of lags, the wool carried by the fork
over the endless lags when the fork receeds is left or deposited evenly
on the lags, and the thinner or outer edge of the wool is presented to
the squeezing rollers, and "balling" of the wool or fibre is avoided.
5
The standards carrying the squeezing rollers are constructed and 1
arranged in position relative to the washing bowl that the said rollers
are over or above the bowl, whereby the waste trough and conducting
pipe for returning the suds squeezed by the action of the rollers out of
the wool to the washing bowl is dispensed with.
The motion of the forks may be reversed for the purpose of "washing 1
back" or returning the wool to the feed end of the bowl, whereby it is
the longer exposed to the washing operation, the reversing motion being
obtained by means of bevel gear and change pullies.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Jefferson, Cornelius Jefferson, Lazarus 2
Jefferson, and Mordecai Jefferson in the Great Seal Patent Office
on the 20th January 1876
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JOSEPH
JEFFERSON, CORNELIUS JEFFERSON, LAZARUS JEFFERSON, and MORDECAT
JEFFERSON, all of Bradford, in the County of York, Machuno Makers 2
and Iron and Brass Founders, send greeting.

ninth year of er reign, did, for Herself, Her heirs and successors, give {

Mordecai Jefferson, our executors, administrators, and assigns, or such
others as
the said Joseph Jefferson, Cornelius Jefferson, Lazarus
Jefferson, and Mordecai Jefferson, our executors, administrators, and

time and at all times thereafter during the term therein expressed,
should and lawfully might make, usc, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR
WASHING WOOL AND FIBRES," upon the condition (amongst others) that
we, the said Joseph Jefferson, Cornelius Jefferson, Lazarus Jefferson,
and Mordecai Jefferson, our executors or administrators, by an instru-
ment in writing under our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said Letters

page_text: to the elongated boss R, which boss runs loosely on the shaft M; S is a
fast pulley; when the strap is on the pulley $ the bevel wheel T will by
means of the wheel W and shaft Y operate the forks in the direction of
the crocper and rollers, but when the strap is on the pulley P the
shafts M and Y are reversed, because the bevel wheel becomes the driver,
and the motion and action of the forks are reversed so as to secure a
washing back or subjecting the fibre to a more thorough washing before
being deposited upon the creeper and passed from the machine.
Having thus fully described the nature and particulares of this our
said Invention, we would have it understood that we are aware that
spiked lags have been employed, as described in the Specification of
William Brown, No 2252, A.D. 1853.
And we would have it understood that we lay no claim to any of the
parts herein referred to, described, or shewn in the Drawings, when
considered separately, nor do we claim the combination of an endless
sheet of lags or creeper with squeezing rollers; but what we do claim is,
the construction and use of machinery for purposes aforesaid, having
the standards II, H, rollers J, K, washing bowl L, the plain or unspikod
creeper A, and the fork E arranged and combined in the manner
described, and as such arc shewn by the Drawings annexed. And in
combination and conjunction therewith we claim for the purpose
described the use of the reversing gearing, shewn at Figs 3 and 4 of
the Drawings.
In witness whereof, I, tho said Joseph Jefferson, have, for and on
behalf of myself and the said Cornelius Jefferson, Lazarus
Jefferson, and Mordecal Jefferson, hereunto set my hand and
seal, this Twelfth day of January, in the year of our Lord One
thousand eight hundred and seventy-six.
