Year: 1856

page_text: LETTERS PATENT to Samuel Middleton, of St. George's Row, Southwark,
for the Invention of "AN IMPROVEMENT IN THE LEATHER-COVERED ROLLERS
USED IN SPINNING MACHINERY."
Sealed the 20th March 1856, and dated the 8th January 1856.
PROVISIONAL SPECIFICATION left by the said Samuel Middleton at
the Office of the Commissioners of Patents, with his Petition, on the
8th January 1856.
I, SAMUEL MIDDLETON, of St. George's Row, Southwark, :do hereby declare
the nature of the Invention for "AN IMPROVEMENT, IN THE LEATHER-COVERED
ROLLERS USED IN SPINNING MACHINERY". to be as follows:
Heretofore it is well known that rollers used in spinning machinery. have
been covered with leather, and that such coverings: have each had a seam.or
join longitudinally of the roller; such seam or join having been made by
sewing or cement. Now, my improvement consists of covering such. rollers
with leather made without a seam, for which purpose the covering of a roller
is made from a tubular piece of leather, produced by tanning or rendering into
leather the skin of the tails, legs, or parts of the animal of small diameter ;
or; in place of such tubular .leather, a tube is produced in each case from a
dise drawn on to a mandril.and through a die.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
MIDDLETON, of St. George's Row, Southwark, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of January, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Samuel Middleton, Her special licence that I, the said Samuel Middleton,
my executors, administrators, and assigns, or such others as I, the said Samuel
Middleton, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVEMENT IN THE LEATHER-
COVERED ROLLERS USED IN SPINNING MACHINERY," upon the condition (amongst
others) that I, the said Samuel Middleton, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be. performed, and cause the
same to be. filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Middleton, do hereby declare tho
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement-thereof, that is to say :-
Heretofore it is well known that rollers used in spinning machinery have
been covered with leather, and that such coverings have each had a seam or
join longitudinally of the roller, such seam or join having been made by
sewing or cement. Now, my improvement consists of covering such rollers
with leather made without a seam, for which purpose the covering of a roller
is made from a tubular piece of leather, produced by tanning or rendering
into leather the skin of the tails, logs, or parts of the animal of small
diameter.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
In place of covering the rollers of spinning machinery with pieces of

page_text: leather folded over them, and then by joining the edges, and thus forming a
seam or join in each case, as heretofore, I use tubular pieces of leather, formed
by tanning the skins of calf or other animal's tails or of their legs.
The tanning is performed in like manner to that in which leather used for
like purposes has been heretofore tanned, which process is well understood,
and forms no part of my Invention. The tubular leather thus produced is,
when in a damp state, placed on proper rollers, such as heretofore used in
spinning machines, and the surfaces of the rollers are made true and uniformi
by forcing the same with the leather thereon through holes or dies of the size
desired.
In witness whereof, I, the said Samuel Middleton, have hereunto set
my hand and seal, this Ninth day of June, in the year of our Lord
One thousand eight hundred and fifty-six.
