CERTAIN IMPROVEMENTS APPLICABLE TO RAISING, THE PILE AND DRESSING WOOLLEN AND OTHER CLOTHS
Year: 1827

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
SEVILL, of Brownshill, in the Parish of Disley, in the County of Gloucester,
Clothier, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth
did, by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Twentieth day of November, One thousand
eight hundred and twenty-seven, in the eighth year of His reign, give
and grant unto me, the said Samuel Sevill, His especial licence that I,
the said Samuel Sevill, my, exors, adñors, and assigns, and such others
as I, the said Samuel Sevill, my exors, admors, and assigns, should at any
time agree with, and no others, from time to time and at all times during the
term of years therein mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "CERTAIN IMPROVEMENTS APPLICABLE TO RAISING, THE
PILE AND DRESSING WOOLLEN AND OTHER CLOTHS;" in which said Letters Patent
there is contained a proviso that I, the said Samuel Sevill, shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in His Majesty's High Court of
Chancery within six calendar months next and immediately after the date of
the said in part recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Sevill, do hereby describe the manner in which my said Invention. is
to be performed by the following description thereof (that is to say) :-
My said Invention consists,-

page_text: First, in the application of springs to the blades of cloth shearing machines,
whether the same be applied to the ledger blades or to the running blades,
for the purpose of keeping the blades always in contact with each other, and
thus compensating for the wearing of the blades by the continued friction,
and keeping a regular and ascertained pressure of one blade against the
other; and,
Secondly, in giving additional elasticity to the boards on which wires set
in leather are used for raising the pile of cloth.
And in further compliance with the said proviso, I, the said Samuel Sevill,
do hereby describe the manner in which my said Invention is to be per-
formed, by the following description thereof, reference being had to the
Drawing annexed, and to the figures and letters marked thereon (that is
to say)-

DESCRIPTION OF THE DRAWING (which is to a scale of six inches to a foot).
Figure 1 is a Plan of part of an ordinary shearing machine, and shows.one
of my said improvements as applied to a ledger blade. A is a cylinder with the
spiral running blades. B is the ledger blade, fixed to the bar C, which is
moveable in the bearings D, D. E is a lever upon which the spiral spring F
presses, in order to give the ledger blade, more or less pressure against the
running blades. G is a round bar, carrying the spiral spring F... This bar is
moveable in the brass bearings.D, D.. H, H, are screw bolts for fixing these
double bearing brasses to the cast-iron back I. K is a ratchet wheel with a paul
fixed to the bar G. L is a square. end to the bar G, to which a spanner or
wrench may be applied for strengthening or relaxing the spring F. M is a
loose joint or paul fixed to the back I for holding the ratchett wheel K.
Figure 2 is an end view of my said improvement as applied to the ledger
blade, and the same letters of reference mark the same parts in both this Figure
and the last. It should here be stated that two or more of these springs, and
the necessary apparatus connected therewith, may be used according to the width
of the cloth to be sheared. Figure 3 is an end section of, one of my said
improvements as applied to running blades. r, r, r, r, are the four blades, which,
it will be seen, are set into holders or shafts which pass through the rim of the
support wheel X, and are pressed outwards by the spiral springs e, e, e, e,
which act also against the central cylinder Y as a point of resistance, and
press the blades outwards with a degree of force which must be regulated
by experiment, according to the nature of the cloth to be sheared. or dressed.
Figure 4 is an end section of a wire board for raising the pile of cloths, with
wires set in leather, which board I make to turn on a hinge at Z; and sup-

page_text: ported by the spring W, and thus add a great additional elasticity to the action
of the cards in raising the pile of the cloth.
Now whereas I claim as my Invention the following improvements (that is
to say) :-
First, the application of springs to the blades of shearing machines used
in the process of dressing cloth, and for the purpose aforesaid, whether the
same be applied to the ledger blade or running blades, and whether the same
be flat springs or spiral springs; and,
Secondly, the giving of additional elasticity to such boards as are used for
holding the wire cards for raising the pile of cloth by hanging such boards
on hinges, and applying the springs under such boards, as shewn in the
Drawing.
And such improvements being, to the best of my knowledge and belief,
entirely new, and never before used within that part of His said Majesty's
United Kingdom of Great Britain and Ireland called England, His Dominion
of Wales, or Town of Berwick-upon-Tweed, I do hereby declare this to be
my Specification of my said Invention, and that I do verily believe this my
said Specification doth comply in all respects, fully and without reserve or
disguise, with the proviso in the said herein-before in part recited Letters
Patent contained; wherefore I hereby claim to maintain exclusive right and
privilege to my said Invention.
In witness whereof, I, the said Samuel Sevill, have hereunto set my
hand and seal, this Twentieth day of May, in the year of our Lord
One thousand eight hundred and twenty-eight.
Inrolled the Twentieth day of May, in the year of our Lord One thousand
eight hundred and twenty-eight.
