page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL.
WALKER, of Millshaw, near Leeds, in the County of York, Clothier, send
greeting.
WHEREAS His present most Excellent Majesty King William the
Fourth, by His Letters Patent under the Great Seal of Great Britain,
bearing date at Westminster, the First day of March, in the second year
of His reign, did, for Himself, His heirs and successors, give and grant
unto me, the said Samuel Walker, His especial licence, that I, the said
Samuel Walker, my executors, administrators, and assigns, or such others
as I, the said Samuel Walker, my executors, administrators, or 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 IN
GIG MACHINES FOR DRESSING WOOLLEN CLOTHS;" in which said Letters Patent
is contained a proviso, obliging me, the said Samuel Walker, by an in-
strument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same
is to be performed, and to cause the same to be inrolled in His Majesty's
High Court of Chancery within six calendar months next and immediately

page_text: 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 Walker, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are par-
ticularly described and ascertained in and by the Drawings hereunto
annexed, and the following description thereof, that is to say :-
My improvements in gig machines for dressing woollen cloths consist
in the novel arrangement of the rollers, and the parts connected thereto, that
carry and conduct the cloth over the teasle cylinder, by which I am enalbed
to keep the cloth properly distended and even during the operation of raising
the pile. In the Drawing hereunto annexed Fig. 1 is a front elevation of
a gig upon my improved plan. Figure 2 is a transverse section of the same.
Fig. 3 is an elevation of the right hand end of the machine, and Fig. 4 of the
left-hand end of the machine, in which the positions of the teasle cylinder and
the several rollers are seen, and the toothed wheels and other appendages by.
which they are driven. a is the large gig barrel or teazle cylinder, into which
teazles, cards, or brushes may be placed, to which rotary motion may be given
in the ordinary way, or by any other means which may be found eligible.
6 is the roller upon which it may be supposed that the cloth has been in the
first instance rolled or wound. c'is a similar roller driven by gear attached to
the end of its axle, the periphery of the roller 6 or of the cloth which is rolled
upon it always bearing upon the periphery of this roller c, and consequently
tnrned by the friction of contact. d is another roller on to which the cloth
is intended to be rolled as it is drawn from the roller b. e is a similar roller
to c, driven by gear at the end of its axle, which by friction turns the roller d
that bears upon it. The tension roller f has its axle mounted in the segment
racks 9 as usual, and it is raised or depressed by turning the shaft and
pinion h, h. The roller b with the cloth upon it being mounted in the machine,
as shewn, the end of the cloth is brought round and under the driving roller c,
and the tension roller f, and is then conducted over the roller e and made fast
to the roller d by its forell and canvass, and the surface of the cloth is made
to bear upon the periphery of the teasle cylinder to any extent more or less, as
may be required, by raising or depressing the tension roller. In order to put
the gig in action, rotatory motion is given to the teazle cylinder by toothed
gear, a clutch box locking it to the power shaft i, as shewn in Fig. 3. A
pinion fixed on the shaft of the teasle cylinder takes into a carrier wheel.k
which drives the loose wheel l on the axle of the roller c, and this wheel takes
into and drives a similar loose wheel m on the axle of the roller c. Now by

page_text: i
locking the clutch to the wheel m on the axle of the roller e, the roller d will
be made to revolve and to draw the cloth from the roller b under the roller c
over the surface of the gig cylinder under the tension roller f up to the roller e,
when it rolls or winds upon the roller d, until all the cloth has been drawn
from the roller 6 upon which it was first rolled. In order to take the cloth
back again through the machine for the purpose of being further operated
upon by the teasles, the clutch, must be unlocked from the wheel m so as to
allow that wheel to turn freely upon its axis, and the clutch of the wheel be
projected in order to lock that wheel to its axle. The roller c will now be
driven round by the toothed gear, and cause the roller 6 to turn also, and to take
up-or-wind-on-the cloth in the same way as roller d above described. This
alternation of the cloth from the roller 6 to d and from d to 6 may be continued
until the pile of the cloth has been sufficiently raised; and in order to keep the
cloth always at, a suitable tension, a pulley, and a break is attached to the reverse
end of the axles c and e, as shown at Figure 3. The pulley o is fixed on the
shaft c and the pulley p on the shaft e, and a stud or pin is fixed in the frame
at q, to which the ends of the two cards are made fast; these cards are carried
round the pulleys o and p, and attached at their reverse ends to weighted
levers; hence it will be seen that the friction upon either of the pulleys in
unwinding the cloth, will by the tension of the cord be so considerable as to
keep the cloth tightly distended as it is drawn from the roller b, but in winding
on, the cord will be relieved and the friction will be so trifling as not to
impede the rotation in any perceptible degree.
In conclusion, I would remark that in the accompanying Drawings there is
shewn upon the shaft i two different sized driving wheels, one upon each end,
by which the speed of the gig barrel may be altered as desired, by throwing
one or other into gear with the spur wheel upon the axis of the gig barrel by
means of the sliding clutches, and that by placing an intermediate wheel
between the pinion upon the axle of the gig barrel and the wheel k, the
barrel may be made to reverse its motion, and yet that of the cloth continue
unaltered, the wheel k and intermediate wheel being alternately thrown into
gear with the pinion upon the axle of the gig barrel; but these contrivances I
do not consider as new.

In witness whereof, I, the said Samuel Walker, have hereunto set my
day of August, in the year of our
hand and seal, this

SAMUEL (L.B.) WALKER.

page_text: AND BE IT REMEMBERED, that on the Thirteenth day of August, in
the third year of the reign of His present Majesty King William the Fourth,
the said Samuel Walker came before our Lord the King in His Chancery,
and acknowledged the Instrument aforesaid, and all and every thing therein
contained and specified, in form above written. And also the Instrument
aforesaid was stamped according to the tenor of the Statute made in the
fifty-fifth year of the reign of His late Majesty King George the Third.
