date of the said Letters Patent next and immediately ensuing, and fully to be
compleat and ended, according to the Statute in such case made and provided;
in which said Letters Patent is contained a proviso that if I, the said Andru
Cederbarg, should not particularly describe and ascertain the nature of my
said Invention, and in what manner the same is to be performed, by an
instrument in writing under iny hand and seal, and cause the same to be
inrolled in His said Majesty's High Court of Chancery within one calendar
month next and immediately after the date of the said Letters Patent, that
then the said Letters Patent, and all liberties and advantages whatsoever
thereby granted, should utterly cease, determine, and become void, anything
therein-before contained to the contrary thereof in anywise notwithstanding, as
in and by the said Letters Patent,..relation being thereunto had, may more.
fully and at large appear.
NOW KNOW YE, that I, the said Andru Cederbarg, in compliance with
the said proviso, do hereby describe and ascertain the nature of my. aforesaid
Invention, and declare thereof in manner following (that is to say):
That there is a foundation or bed of. wood, nine feet long, two feet nine
inches wide, and two inches and. an half. thick, placed upon five cross rails, four-
inches square, to which cross rails the bed or foundation is fastened. by eight
screw bolts in each rail; upon the said foundation or bed are fixed pairs of
pillars, one at each end, and in the middle one or two pair;. each pair of pillars

page_text: is formed by one upright and one sloping, four inches square and two feet two
inches high, or which may be both upright or both sloping and of any thick-
ness, supporting a cross rail, twenty-one inches long, five inches deep, and
three inches thick, or of any other size; on which. cross rail are fixed double
gudgeons to receive the shaft of the, machine, and in each double gudgeon are
a number of friction rollers, three, five, seven, or more. Between each end
pillar and the centre one is placed on the said bed or foundation a table, on
which tables the business is to be executed, each of which are four feet long,
made with a circular sweep to the face of the machine, and is supported in
front by a rail, twelve inches high, four feet long, and four inches thick.
Under each end of each of the said rails is fixed a cross sliding bar, three feet
long, five inches deep, and two inches thick; in the bottom of each end of
which said cross bars is fixed a friction roller made of iron, steele, or.other
metal, and under each of the said cross rails is placed on the bed or foundation
an iron plate for the said rollers to move upon; each of the said tables are sup-
ported on the back part by three or more strong braces, one placed at each
end and resting upon the afore-mentioned cross rail, and fastened to the table
with bolts and nuts, the other in the middle of the table with a friction roller
at the bottom of it, resting on an iron plate, fixed in the bed or foundation for
the said roller to move upon. At the back of each of the said tables are also
two braces, one at each end or near it, which braces are made to receive two
multiplying pullies, round which a cord or chain goes, and is fastened to the
upright rail which supports the front of the table. An iron cross bar is fixed
in the center of the two largest pullies, to which the cords or chains are
fastened, on which said cross bar a hand bar or treadle is fixed, to be used by
the hand or foot, by which means the table is easily moved back to two stops
placed on the bed or foundation, or as far as is necessary. In the front of
each table are two braces, one at each end, fastened to the sloping pillar with
bolts and nuts. Each brace is made to receive two multiplying pullies, over
which a cord or chain goes, one end of which is fastened to the upright rail
which supports the table in front; at the other end are hung weights sufficient
to bring the table forward to the machine and keep it to the work when the
hand or treadle is discharged from the hold at the back of the table; there are
also two stops in the front of the table, as at the back, to prevent it getting
out of the proper place. The iron shaft or cylinder of the machine is about
nine feet long and four inches diameter, of cylindrical or round shape, and has
three rabbitts or groves in which it is fitted to and placed on the gudgeons and
friction rollers on the top pillars before mentioned, whereon it runs. This
cylinder or shaft may be of any length which the tables require, and is made

page_text: to receive a number of levers, which levers are made with a round eye to fit
the shaft, in which eye is a binding, screw to fix it to the shaft. The said
levers are about fifteen inches long, seven of which from the shaft is square or
flat, the rest is a.cylindrical round; on which round. part is put a socket. of
brass or iron, made with an opening at the end to receive a roller, polisher, or
grainer, made of glass, wood, stone, metal, or bone, which said roller, polisher,
or grainer is fixed in the opening of the said socket by means of a binding
bolt and nutt, and may be removed and replaced as occasion require. There
are also one or two binding screws upon the round part of the sockets to keep
it firm to the round part of the lever; there are also two counter nutts on the
lever, one before and one behind the socket, to regulate the length and also the
position of the said rollers, polishers, or grainers. The number of levers upon
the said shaft or cylinder. must be regulated by the length of the shaft and the
nature of the business they have to do; they are so fixed that only a small
number at a time may strike on the goods which are placed on the table. At the
end of the shaft is fixed and placed a large fly wheel, and a handle put thereon
to turn the same, by which the whole machine is regulated and given power to,
and which may be worked by one or more men, or by a horse mill; water
mill, wind mill, or by a steam engine, or by weights and machinery, either
of which may be applied to the same; which said machine or instrument is
for the use and purpose of polishing, glazing, and graining divers sorts of
leather of different colours, sorts, and .qualities, called Morocco, leather and
Spanish leather and other leather, and also various other articles and things
such as linens, cottons, callicoes, silks, stuffs, and papers; which said articles
and every of them. are placed upon the said tables of the said machine, and
the same is put. in motion by the turning of the wheel, and the articles are
struck by the polishers that are in the ends of the sockets and upon the levers
fixed to the said cylinder or shaft, as aforesaid; and by an addition to the said
machine to be used: occasionally for the charging and discharging of linens,
cottons, callicoes, silks,.stuffs, and. other goods, in manner following, that 'is to
say, one small wheel with a certain number of cogs is fixed and placed on the
shaft between the fly wheel and the pillar, which is to act upon a larger wheel
below it,. fixed in the centre, on which larger wheel are also a number of cogs
to act upon two other wheels with cogs, one on each side, each of which are to
act upon outer wheels, through the centre. of each of which outer wheels is
fixed the end of the roller, on one of which rollers is placed or put the articles
or goods before they are polished; the other roller is to receive the said
articles or goods when glazed or polished; and during the operation anotlier
bar or roller is placed in the centre to prevent the goods. receiving damage;

page_text: which said bars or rollers act upon upright braces at each end, both before and
behind the machine, and is united from one, table to another by fork joints.
And which instrument or machine may be made double, treble, or to greater
extent, and worked by the same wheel; or the same may have another large
fly wheel at the other end of the said machine. And which said instrument or
machine, and the various component parts thereof, may be made and manu-
factured of various other articles and things than herein described, and of
various sizes and thicknesses than herein mentioned, either by extending or
contracting the same in all or any part or parts thereof, as need or occasion
may require.
In witness whereof, I, the said Andru Cederbarg, have hereunto set my
hand and affixed my seal, the Twenty-seventh day of March, One
thousand seven hundred and ninety-eight.
