ATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I. JONATHAN
RIDGWAY, of Manchester, in the County of Lancaster, Plumber, send greeting.
WHEREAS His most Excellent Majesty King George the Third, did, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Fourth day of April, in the fifty-
fifth year of His reign, give and grant unto me, the said Jonathan Ridgway,
my executors, administrators, and assigns, His especial licence, full power, sole
privilege and authority, that I, the said Jonathan Ridgway, my executors,
administrators, and assigns, and every of them, by myself and themselves, or by
our deputy or deputies, servants or agents, or such others as I, the said Jonathan
Ridgway, my executors, administrators, or assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the term of
years therein expressed, should and lawfully might make, use, exercise, and vend,
within that part of the United Kingdom of Great Britain and Ireland called
England, the Dominion of Wales, and Town of Berwick-upon-Tweed, my Inven-
tion of "Ax IMPROVED ROLLER TO BE USED IN PRINTING CLOTH MADE OF COTTON
OB LINEN, OR BOTH;" in which Letters Patent there is contained a proviso,.
obliging me, the said Jonathan Ridgway, particularly to describe and ascertain
the nature of my said Invention, and in what manner the same is to be per-
formed, by an instrument in writing under my hand and seal, and to cause
the same to be inrolled in His said Majesty's High Court of Chancery within.

Patent, as in and by the said Letters Patent, relation being thereunto had,
may more fully and at largo appear.
NOW KNOW YE, that in pursuance of and in compliance with the said
recited proviso, I, the said Jonathan Ridgway, do hereby declare that the
nature of my said Invention, and the manner in which the samo is to be per-
formed, is as herein-after mentioned.
The exterior shell or outside of the printing roller consists of a hollow
cylinder of lead, or tin, or a mixture of lead and tin, or of any cheap metal, or
mixture of metals, that can be readily melted and cast in moulds similar to
those used by plumbers for casting lead pipes, and that will readily unite by
heat with lead, or tin, or a mixture of lead and tin. The metal I prefer is
lead, with a small mixture of tin, equal in weight to about one-fifth part of the
lead. My method of making the shell is as follows:-
Fig. 1 represents a mandrel or core of cast, or-malleable iron, steel, copper, 1
brass, or other hard metal, or mixture of metals, with a groove cut or made in
&
right line, about one-fourth of an inch, in depth, and from a quarter to half
an inch in breadth, the whole length of the body of the core; this depth_and
breadth I consider as a convenient one, but the depth and breadth may be varied
without much inconvenience. This groove will prevent the core, as well as
tho working mandrel, hereafter to be described, from turning round within the
shell, but not from being drawn out of it in a longitudinal direction; 6 is a
loose collar, intended to keep the core in the centre of the mould; c,. c, are
hoops of iron, copper, brass, or any other hard metal, of about one-eighth part
of an inch in thickness, and about two inches in breadth, or of any other con-
venient broadth and thickness, with tabs or parts projecting inwardly, to fit
and slide within the groove in the core; in these hoops I make holes, or make
tabs, or projecting parts on the outsides of them, to make them fast to or within
the shells; I then place the hoops upon the core at such a distance from each
other as to form the internal surface of each end of the shell or roller. The
core thus adjusted, is placed in a pair of moulds of the size of the intended
shell, the loose collar is brought in contact with the upper hoop, and the

page_text: melted metal is poured into the moulds in the same may that plumbers cast
their pipes; the hoops are thus become fastened to: the shell by the metal
running into the holes or upon the projecting parts; the two hoops, may bo
united by continuing the metal through: the intermediate space, but. this: Icon.
sider, as unnecessary and expensive.
Fig. 2 is a working mandrel or axle of iron; or. other; hard metal, grooved,
and made accurately to fit the shell after the shell-has been cast as above; on
this mandrel or axle a collar or shoulder is fixed at d to support ono end
of the shell, the other end is to be supported by a strong washer or moveable
collar. to be put on the mandrel after it has received the shell, and this
moveable collar is to be held firmly up to the shell by a screw nut, firmly
keyed up to the collar, as at g, f, or the collar may be firmly forced up by a
wedge or cotter driven through an eye or hole in the mandrel made for the
purpose, or by any other mechanical means proper for that purpose; the
object being to fix firmly the body or shell of the roller between the two
collars d and g, f, to prevent it from expanding in length, either in any of the
subsequent operations for finishing the same with patterns or afterwards, in
the process of being worked or used. The working mandrel and shell, when
thus put together, form my improved roller. This roller may afterwards bo
finished for printing in any of the ways now in use.
The Invention I claim is, for making a roller with a detached exterior shell,
of such metal or metals as aforesaid, so that different shells may be used in
succession on the same working mandrel, and supported at each end by collars
to prevent expansion, as herein-before mentioned. And I claim the same,
whether such shells are made with or without the hoops, herein-before
mentioned.
In witness whereof, I, the said Jonathan Ridgway, have hereunto set
my hand and seal, the Nineteenth day of April, in the year of our Lord
One thousand eight hundred and fifteen.
