page_text: DANIELL'S SPECIFICATION.
TO ALL TO. WHOM THESE PRESENTS SHALL COME, I, JOSEPH
CLISILD DANIELL, of Limply Stoke, in the Parish of Bradford, in the County
of Wilts, Clothier, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent, under the Great Seal of Great Britain, bearing date
at Westminster, the Twenty-sixth day of May, in the tenth year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Joseph Clisild Daniell, His special licence that I, the said Joseph Clisild Daniell,
my exors, admors, and assigns, or such others as I, the said Joseph Clisild
Daniell, my exors, admors, 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
expressed, should 'and: lawfully might make,, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of:
"A CERTAIN IMPROVEMENT IN MACHINERY APPLICABLE TO. THE DRESSING OF WOOLLEN
CLOTH;" in which said Letters is contained a proviso, obliging me, the said
Joseph Clisild Daniell, by an instrument 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 enrolled
in His said Majesty's. High Court of Chancery, within six calendar months next
and immediately after the date of the said 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.
Joseph Glisild Daniell, do hereby declare, that the nature of my said Inven-
tion of an improvement in machinery, applicable to the dressing, of woollen
cloth is described and ascertained-in-manner following, that is to say:
The machinery to which my improvement relates is known, by the name of

page_text: .
gig mills for dressing woollen cloth. My improvement is most particularly
applicable to those gig mills which are intended to dress or raise a pile upon
the surface of woollen cloth by means of pointed wire cards fastened on
boards which are affixed to the circumference of the revolving barrels or
cylinders of the gig mills. My improvement consists in a mode, heréin-after
particularly described, of applying and attaching the cardboards (in which the
leathers of the pointed wire cards are nailed) to the cylinder boards, which
form the circumference of the revolving barrel of the gig mill, with springs
so interposed between the said cardboards and the cylinder-boards_as_to
permit the said cardboards. to yield or recede a little towards the axis or 1
centre of the barrel whenever the points of the wire cards take too strong
hold of the cloth, in order that by such yielding and retreating of the cards
from the cloth the same may escape being injured by the points of the wires.
I apply my said improvement to gig mills which have bearing rails or perches
fastened to the circumference of the 'revolving barrel of the gig mill parallel 1
to the axis thereof,.as has been heretofore practised, such bearing rails or
perches being placed in the interval between the several cylinder boards
whereon the cardboards are applied, such cardboards, being attached by the
mode which constitutes my improvement; the said-bearing rails-or-perches-
being situated, in respect to the situation of the points of the wire cards, sö, as 2
to support or bear up the cloth in the manner of fenders, in order that how--
ever tight the cloth may be strained or drawn over a part of the circumference
of the revolving cylinder the cloth may not receive any more action from the
points of the wire cards than is desired or than will be sufficient to dress and
raise the pile properly without injuring the texture of the cloth. "Or, instead 2
of bearing rails and perches fastened to the circumference of the barrel, it is.
better to use small rollers in place thereof, according to a former improve-
ment, for which His Majesty's Letters Patent were granted to me, bearing
date the Twenty-eighth of September, One thousand eight hundred and twenty-
eight, and which improvement I did fully describe in my Specification, dated 3
the Sixth of March, One thousand eight hundred and twenty-nine, and which
was enrolled in the Court of Chancery the Eighteenth, day of the same month,
wherefore I recommend my present improvement to be used in combination. -
with my former improvement aforesaid; and instead of screwing the card-
boards fast upon the cylinder boards, as directed in my former Specification, I s
now use the following mode, which constitutes my present-improvement:
Figure 1 of the Drawing hereunto annexed is a transverse section of a
portion of the barrel of a gig mill, shewing part of one of the circular rims D,
with one of the cylinder boards E fastened to the rim, also one of the card-.

page_text: boards Fattached to the cylinder board E, by the mode which constitutes my
present improvement. L, L, represent two of the small rollers, which con-
stituted my former improvement, as herein-before recited. Figure 2 is a plan
of a portion of the cylinder board E, shewing one cardboard F; and Figure 3
is a longitudinal section of the cylinder board and cardboard, corresponding. to
Figure 2. a, a, are two screws, which are screwed into the cylinder board E;
they have holes formed across through their heads to receive two pins or
hooks b, b, which are fastened to that edge of the cardboard F which goes
first when the barrel revolves; the hooks b, b, are formed at the ends of two
slips of metal c, c, which are let into the back of the cardboard F across the
breadth thereof, and fastened by screws with their heads countersunk. The
pins b, b, being thus lodged in the holes through the heads of the screws a,
form as it were a pair of hinges, by which the cardboard F is attached to the
cylinder board E. 2, 2, are steady pins, which are driven tight into the
eylinder board E, and project outward therefrom. The upper ends of the
pins 2 are received into holes formed through the pieces or slips of metal c, c,
at the back of the cardboard F, and the pins 2 retain the cardboard from
moving endways, whereby they prevent the hooks b, b, withdrawing from
the holes through the heads of the screws a, a. e, e, are spiral springs formed
of brass wire, coiled up into short curls; they are placed round the steady
pins 6, 6, and rest upon the cylinder board E; the upper ends of the springs
e, e, bear upwards beneath the under sides of the slips of metal c, c, which
extend all across the cardboard, as before mentioned, see the dotted lines
in the plan, Figure 2; hence, the elasticity of the springs e, e, tends to elevate
the cardboard F, or to move it on its hinges a, a, so as to press it outwards
from the axis or centre of the barrel, or, in other words, the springs e, e, resist
the approach of the cardboard towards the axis of the cylinder. The springs
é, e, may be regulated so as to act with more force to press the cardboard F
outward from the axis of the barrel by applying one or more washers or small
round flat pieces of metal having holes through their centres, see Figure 4,
between the said springs e, e, and the cylinder board E, the said washers being
dropped over the pins 2, 2, before the springs e, e, are applied upon those pins.
h, Figure 1, is a stop screw, which is formed like the letter T, and serves to
catch the edge of the cardboard, in order to prevent its rising beyond the
required distance from the cylinder board E, and thus limit the action where-
with the springs e, e, force the cardboard off from the cylinder.board E.; but
the said stop screw h does not prevent the yielding of the cardboard towards
the cylinder board whenever the points of the wire cards take too much hold of
the cloth. By screwing the stop screw à further into the cylinder board E, or

page_text: _by_screwing it out therefrom, the position in which its tee head will stop the
cardboard can be regulated; and in like manner, when the cardboard is
femoved either one or both of the screws as a can be screwed in or out of the
cylinder board in order to adjust the position of the cardboard, so that the
points of the wire cards will stand at such a distance from the axis of the
cylinder in respect to the rollers L, L, (or the bearing rails 'or perches which
may be used in place thereof,) as may be found necessary to allow the points
of the wire cards to act sufficiently on the cloth, but no more; and yet, if
by accident the 'points of the wire cards should incline to operate too power-
fully, the cardboards will retreat by the yielding of the springs è sofas
to avoid doing injury to the cloth. The stop screw his retained from turning
round of itself by a small wire spring I, which catches in a notch cut in either
end of the tee head h; when it is necessary.to remove the card board from the
cylinder board, the tee head must be turned round a quarter of a turn, and will
then release, that edge of the cardboard to which it applies. The cardboard
may then be turned on its hinges a, a, till it rises clear of the steady pins 202,
after which the cardboard may be moved endways so as to withdraw its-pins
6,6, out of the holes through the heads of the screws a, a, whereby the cardboard
becomes quite detached from the barrel.
upon,
Having now described my said Invention, and the mode of applying lit
to use, I hereby declare that I confine my claim of Invention to the particular
mode berein-before described of attaching and applying the cardboards F
the cylinder boards E with springs, which will permit the cardboards to
yield when the points of the 'wire cards take too much hold of the cloth,
the said mode affording the means of adjusting the position of the cardboards
so as to allow the said points of the wire cards to take as much hold of
the cloth as may be required, and also affording the means of readily detaching
and removing the cardboards from the cylinder boards and replacing. them
by other cardboards when necessary...
In witness whereof; I, the said Joseph. Clisild Daniell, have hereunto set
my hand and seal, this Twentieth day of November, in the year of our
Lord One thousand eight hundred and twenty-nine.
