WHEREAS His most Excellent Majesty King William the Fourth, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-fifth day of February, in the fifth year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
William Davis, His especial licence that I, the said William Davis, my
executors, administrators, and assigns, or such others as I, the said William
Davis, my executors, administrators, 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 expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "AN IMPROVEMENT IN MACHINERY FOR DRESSING WOOLLEN OR OTHER
CLOTHS REQUIRING SUCH PROCESS;" in which Letters Patent there is contained a
proviso obliging me, the said William Davis, 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 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
William Davis, do hereby declare the nature of my said Invention, and the

page_text: manner in which the same is to be performed, is described and ascertained as
follows, that is to say:-
This Improvement in Machinery for Dressing Woollen or other Cloths
requiring such Process consists in the application of a metalic bed, adjustable
in its length to the different bredths of cloths to raise the pile or nap upon,
and a wire guard or grating to prevent the too powerfull action of wire cords
upon the cloth under operation. It is represented with appendages by the
Drawings below upon a scale of one inch and a half to a foot, and calculated
for broad cloth; but for other cloths, such as narrows or extra breadths, the
parts may be made in proportion. The cloths may be drawn over the bed by
the usual means, as in brushing machines or gig mills, wire cards, upon a metal
cylinder with rotary motion acting upon it through the wire guard or grating
at the same time. I do not think it necessary to shew the framework, as that
forms no part of this Invention, and being so easy of adoption by any person
that is competent of making the parts herein specified, and which is given in
position for working at Figs. 3 and 4; the same letters in all the figures of the
Drawings indicate the same parts.
Fig. 1, is the wire; it is woven on each side of the opening for the
purpose of nailing to wooden pegs in the iron casting c, or otherwise fixing; or
instead of being woven it may be made in the same manner that slays or reeds
for weaving are made, from six to ten wires of N. Twelve to Twenty may be
the pitch per inch; it will be seen that it is fixed a little oblique. The casting
rests by its pivots d and adjusting screws a, which the frame of the machine
may be made to support.
Fig. 2 is the iron bed shewn horizontal; the part d is the shell, and c are
sliding pieces moveable in the shell by means of the handles and pinions g,
taking into the racks formed in the ends of the sliding pieces e, the upper pro-
jecting edges of the sliding pieces e are formed into wedge shape, which may be
seen by the section. Fig. 3 is a front view of the bed and guard in the position
for working. Fig. 4 is a end view of the same, shewing also how the cloth may
be drawn, as in brushing machines. The projecting ends of the shell slide
in vertical grooves in the framing, and is supported by the excentric pieces i
on the bar k, and is lowered when necessary by lifting the handle 1. The bed
is adjustable to the cylinder or cards by means of the supporting screws m, n.
Fig. 4 shews the position of the iron cylirder covered with cards for raising
the pile or nap, and o another cylinder grooved on the surface for the purpose
of smoothing the face of the cloth. It is indispensable that the beds and
cylinder be made very acurate. It will be found that the present improvement
in machinery for raising the pile is the first and only instance of the appli-

page_text: cation of a wire grating guard for protecting the cloth when under the
operation of raising; also of the metal bed adjustable to the breadth of cloth
to raise the nap upon by the action of wire cards, &c., upon a cylinder; by
means of this bed the cloth can be raised without raising the list of the piece
of the width of the bed determining the width of cloth to be raised by the
cards, &c.
In witness whereof, I, the said William Davis, have hereunto set my
hand and seal, the Twenty-second day of August, in the year of our
Lord One thousand eight hundred and thirty-five.
(L.S.)
AND BE IT REMEMBERED, that on the Twenty-second day of August,
in the sixth year of the reign of His Majesty King William the Fourth, the
said William Davis came before our said 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.
