AN IMPROVED METHOD OF MAKING A NEB OR NEBS, SLOT OR SLOTS, IN SHELLS OR HOLLOW CYLINDERS OF COPPER, BRASS, OR OTHER METALS, OR MIXTURE OF METALS, FOR PRINTING OF CALICOS, MUSLINS, CLOTHS, SILKS, AND OTHER ARTICLES
Year: 1830

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
Cook, of Birmingham, in the County of Warwick, Brass Founder, send
greeting.
WHEREAS, I did, by Petition, represent to His most Gracious Majesty
King William the Fourth, that I had invented "AN IMPROVED METHOD OF
MAKING A NEB OR NEBS, SLOT OR SLOTS, IN SHELLS OR HOLLOW CYLINDERS OF
COPPER, BRASS, OR OTHER METALS, OR MIXTURE OF METALS, FOR PRINTING
OF CALICOS, MUSLINS, CLOTHS, SILKS, AND OTHER ARTICLES ;" and His said
Majesty being willing to encourage all useful inventions, did issue His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the First day of November, in the first year of His reign, whereby
His said Majesty did, for Himself, His heirs and successors, give and grant
unto me, the said Benjamin Cook, His especial licence, that I, the said
Benjamin Cook, my executors, administrators, and assigns, or such others as I,
the said Benjamin Cook, 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 said Invention; in which said Letters Patent there is contained a
proviso obliging me, the said Benjamin Cook, 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 months next and immediately after the date of the said Letters

page_text: 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
Benjamin Cook, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is described and ascertained
in manner following, that is to say:-
Having prepared solid cylindrical ingots of copper, brass, or other proper
metals, or mixtures of metals, of suitable or convenient lengths and diameters,
and a cylindrical hole being bored, drilled, or otherwise perforated through
each ingot longitudinally, and either through its centre or nxis or in a line
deviating from its centre or axis above or below such centro or axis,-in
order, then, to form and produce one or more neb or nebs, slot or slots, I cut
away or otherwise take out from the interior of the cylinder so bored as afore-
said, either by means of a planing machine, or any other proper and covenient
filing or cutting tool or tools, instrument or instruments, machine or machines,
such a quantity of metal as I may find necessary, so as to leave one or more neb
or nebs, slot or slots, projecting in the interior of the said shell or cylinder of
whatever size, shape, or form I may require, and extending either throughout
the whole length of the said shell or cylinder, or stopping short of the end
thereof, and leaving such a substance of metal uncut as may suffice to form a
collar or shoulder, or inwardly projecting ring at the further end thereof; and
such collar or shoulder is intended to be employed as a stop or means for
drawing out or extending the shell or cylinder upon a mandrell to any length
or size required.
And I claim the exclusive right and privilege of forming a neb or nebs, slot
or slots, in the interior of the said shells or cylinders, either by working out the
surplus metal after boring the cylindrical hole, in the manner herein-before
described, in the axis of the ingot, or not in the axis of the ingot, as is further
explained and described in the annexed Diagrams, being sections of the end of
a shell or cylinder, in which Diagram or section, Figure 1, the Letter A, shews
a holo bored through the axis of the ingot of such diameter as may be found
necessary. The black circle 1 shews the metal required to be removed by
planing, filing, or cutting, and C shews a solid neb or slot there left projecting
in the interior of the said shell or cylinder, and extended to be either square or
of any other form which may be required.
In Figure 2 the Letter A shows the hole bored through the ingot, but not
in its centre or axis. The black part B shews the metal to be removed by
planing, filing, or cutting, as aforesaid, and C shews the neb or slot then
remaining.

page_text: In Figure 3 the Letter A shews a hole bored through the ingot, the black
part B shewing the metal to be removed, and C the ncb or slot then re-
maining.
And I do not hereby intend to confine myself to a single neb or slot in each
shell or cylinder, or to any particular length or diameter of ingots, or to the
diameter of any hole to be bored or cut thereout; but I intend to prepare the
ingots, and make one or more neb or nebs, slot or slots, of shorter or longer
lengths, and either square or of any other shape as may suit my convenience;
and if I wish to extend the length of the shell or cylinder, and the neb
or nebs, slot or slots therein, after boring and cutting such shell or cylinder as
is already described, I either draw them through iron or steel plates, having
suitable apertures therein, or roll them with grooved rollers, or otherwise
elongate them in such manner and by such means or machinery as I may find
most convenient, upon iron or steel mandrells, with a groove or grooves cut in
them longitudinally, and of proper breadth and depth to receive the neb or
nebs, slot or slots formed in the interior of the said shells or cylinders intended
to be drawn out, extended or lengthened; or I bore and cut out the in-
terior of the ingot, shell, or cylinder in manner herein-before described,
when the same is of the full length desired for use in its subsequent work
when finished.
Lastly, I hereby declare that my Improved Method of Making a Neb or Nebs,
Slot or Slots, in Shells or Hollow Cylinders of Copper, Brass, or other Metals, or
Mixture of Metals for Printing of Calicos, Muslins, Cloths, Silks, or other
Articles, consists in the above described employment of a planing, filing, or
other cutting instrument or machine to remove a sufficient quantity of metal
from the interior of the shells or cylinders, and to leave one or more solid neb
or nebs, slot or slots, projecting therein, of any size, shape, or form required,
and is intended to be used for holding the shell or cylinder firm on its working
mandrell, when used in the printing of calicos, muslins, cloths, silks, or other
articles. And for this I claim the exclusive Patent right and privilege.
In witness whereof, I, the said Benjamin Cook, have hereunto set.
my hand and seal, the Fourteenth day of April, in the year of our
Lord One thousand eight hundred and thirty-one.
