A MACHINE FOR RAISING THE WOOL, PILE, OR FIBRES ON WOOLEN CLOTH OR OTHER PIECE GOODS PREPARATORY TO SHEARING, AND FOR DRESSING OR DUBBING CLOTHS EITHER WET OR DRY OTHERWISE THAN BY YERON CARDS OR PICKARDS
Year: 1801

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
JOTHAM, of Bradford, in the County of Wilts, Clothier, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifteenth day of September, in the forty-first year of His
reign, give and grant unto me, the said Thomas Jotham, His especial.
licence that I, the said Thomas Jotham, during the term of years therein
mentioned, should and lawfully might use and exercise, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "A MACHINE FOR
RAISING THE WOOL, PILE, OR FIBRES ON WOOLEN CLOTH OR OTHER PIECE GOODS
PREPARATORY TO SHEARING, AND FOR DRESSING OR DUBBING CLOTHS EITHER
WET OR DRY OTHERWISE THAN BY YERON CARDS OR PICKARDS; in which said
Letters Patent there is contained a proviso, obliging me, the said Thomas
Jotham, by an instrument in writing under my hand and seal, to 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 recited Letters Patent, as in and by the same, relation being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Jotham, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, is herein-after particu-
larly described and ascertained, that is to say:-

page_text: In the several Figures or Drawings in the margin, the circles A, A, B, B, B,
C, C, represent cylinders or rollers, of which they may be considered as the
ends or sections; the line D, D, D, D, &c, represents a webb or piece of cloth
which may be dressed this machine, as follows:-
In Figure 1, the cloth passes over the roller A and under the roller B, and
under the cylinder C and under the roller B, and under the cylinder C and
under the roller B, and over the roller A, and thence proceeding downwards
into a trough or vessel E, E, E, E, (containing awater, or in some cases left
empty,) the ends of which cloth being sewed together (if required) the cloth is
capable of being drawn round an unlimited number of times like a jack towel;
the cylinders C, or the cylinders C, C, is or are faced with teazles, wire, or
hair brushes, or any other facing so constructed or wrought as that the same
shall be well adapted for the purpose of combing, scratching, or clearing out
the fibres, hairs, or staple of the piece in a proper manner, and the said
facing of teazles, wires, or hair brushes, or other materials, aforesaid, is by the
rotation of the said cylinders caused or made to act (in the same or contrary
directions' as required) on the 'cloth while it moves from A to A; the rollers
B, B, B, answer the purpose of conducting the cloth properly; with regard
to the other cylinders, the rollers A, A, called drawing rollers, are also faced
with teazles, or by any other fit and obvious means, are rendered "sufficiently
rough to take hold of the cloth, and the same may be turned or revolved in
either "direction at pleasure, both rollers A, A, being fixed with sliding geer
either of which can be slipped out of geer at will, so that when one A works
in geer the other works out of "geer, and is prevented from "overrunning or
delivering the cloth too fast by means of a lever bridle (or other well-known
nicans) of retarding its progress; "the rollers A, A, B, B, B, are adjustable by
screws applied to their supports (or by any other well-known means), so that
they can be placed higher or lower, and occasion the cloth to bear with a
larger or less surface against the cylinder C or cylinders C-C
ར
Figure 2 represents the cloth passing over the rollers B-B, B, and cylinder
Cor cylinders C, C, instead of under, as it does in Figure 1.
Figure 3 represents the cloth under the same operation' as in Figure 1, with
this exception; that when it shall be deemed more expedient to dress the cloth
without sewing the ends together it is wound upon citler-of-the-rollers A
from off the other, during which the cylinder C or cylinders C, C; perform the
operation on 'the cloth' D, D, D, D, &c.
"Figure. 4" represents "the "cloth under sanie operation as in Figure 3,
excepting that the cloth passes over cylinders B and C, and is "wound-round
under A, A, instead of over it.

page_text: Figure 5 represents the cloth D, D, D, D, &c. under the same operation as
at Figure 4, with only one cylinder C, or-it may be. reversed, as per Figure 3.
Figure 6 represents the cloth under-same, operation as per Figure 1, but
only, with one cylinder C, or it may be-reversed, as in Figure.2. And moreover
I must observe, that tho for the sake of perspicuity, and for the full and perfect
information of all to whom this writing shall come,.I have described and
delincated various forms of my said machine adapted to various circumstances
in which the same may be severally considered as preferable each to cach,
yot, nevertheless, there are also various other forms slightly differing from-thesc,
which I have thought it unnecessary to delineate, because sufficiently obvious
and in effect constituting the same machine.
Lastly, the motion or motions of the operating cylinder C or cylinders C, C,
is or are produced by the usual first movers, namely, wind, water, steam, or
the strength of animals, and the connections between, the driving machinery
from the first mover and the cylinders respectively, as well as between the
several cylinders themselves, are produced and maintained by wheel-work with
teeth, or with straps, chains, ropes, or otherwise, the whole being disposed and
arranged according to circumstances and situations, concerning which no
workman, properly qualified to construct a manufacturing engine, can find the
least difficulty. The operation or action of my said machine may be described
as follows: The cloth intended to be rowed, dressed, or dubb'd is to be
passed thro' the machine, as before described, and in such situation the
cylinders are to be put in motion; the action of one drawing roller A causes
the cloth to move gradually onwards, the other cylinder A being out of geer,
but is assisted by the lever, as before mentioned, in delivering out the cloth
gradually, without the risk of any accident it might be liable to if it were
suffered to remain in geer during the operation, and so vice versa, and during
this passage the fibres, filaments, or hairs, are carded and raised fit for the
operation of the shears; the quantities of surface on either or both (if two) of
the cylinders C which are required to act upon the cloth are to be regulated
as aforesaid by setting or adjusting the rollers A, A, B, B, B, at different
heights; and it is evident that the progress of the cloth through this engine
may be repeated and continued without limit until the manufacturer shall
judge that his piece is sufficiently dressed or prepared.
In witness whereof, the said Thomas Jotham hath hereunto set his
hand and seal, the Twenty-sixth day of February, in the year of our
Lord One thousand eight hundred and two.
THOMAS (L.S.) JOTHAM.
