IMPROVEMENTS IN WRINGING and Mangling MACHINES
Year: 1872

page_text: LETTERS PATENT to George Pigott, of Otley, near Leeds, in the
County of York, for the Invention of "IMPROVEMENTS IN WRINGING
and Mangling MACHINES.”
Sealed the 20th December 1872, and dated the 26th September 1872.
PROVISIONAL SPECIFICATION left by the said George Pigott at the
Office of the Commissioners of Patents, with his Petition, on the
26th September 1872.
I, GEORGE PIGOTT, of Otley, near Leeds, in the County of York, do
hereby declare the nature of the said Invention for “IMPROVEMENTS IN
WRINGING AND MANGLING MACHINES," to be as follows :—
The object of my Invention is by an improved arrangement of the
various parts to facilitate the working and setting of the rollers, and at
the same time to produce a machine at a much less cost of material and
labour than heretofore, and is as hereafter described.
I mount two rollers between framework and in suitable bearings. The
bearings of the upper roller are fixed in position, those of the bottom

page_text: roller are fitted so as to slide freely in the framework and adjustable in
the direction of the upper roller:
The means employed for adjusting the bottom roller is as follows :—
I mount two levers on a carrier fixed between the framework. The
short ends of these levers are brought under the adjustable bearings or
bushes of the lower roller, and connected therewith by rods; the long
ends of the levers are brought to the centre of the machine, at which
point the levers are acted upon by a spiral spring which is placed in a
boss or box in the carrier through which a rod is passed and connected
to the long ends of the levers; the other end of the rod is passed through
the bottom of the boss or box, and on it is screwed an adjusting nut
which operates against the spring. By turning the adjusting nut the
required pressure is transmitted from the spring through the rod to
which the long ends of the levers are attached, and thence to the
rollers.
Instead of the spiral spring in some cases a weight or other equivalent.
may be employed.
By this arrangement the distance between the upper and lower roller
is adjusted, and also the required pressure for wringing or mangling
imparted thereto.
I mount the driving wheel or winch handle on the end of the upper
roller shaft, and to facilitate the turning of the rollers in the proper
direction I provide suitable gearing.
This arrangement of machine is rendered much lighter and cheaper in
construction, and at the same time the adjustment of the rollers is
much facilitated; the action of the levers also is simultaneous when
adjusting the bottom roller, the latter always remaining parallel with the
upper roller.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said George Pigott in the Great Seal Patent Office 30
on the 26th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, George
PIGOTT, of Otley, near Leeds, in the County of York, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of September, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Pigott, Her special licence
that I, the said George Pigott, my executors, administrators, and
assigns, or such others as I, the said George Pigott, 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 "IMPROVEMENTS
IN WRINGING AND MANGLING MACHINES," upon the condition (amongst
others) that I, the said George Pigott, 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 Invention, 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 George Pigott, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings
and to the letters of reference marked thereon, that is to say :-
The object of my Invention is by an improved arrangement as here-
after described of the various parts of wringing and mangling machines,
to facilitate the working and setting of the rollers, and at the same time
to produce a machine at a much less cost of material and labour than
heretofore.
The manner in which this Invention is or may be performed or carried
into practice will be readily understood by reference to the accompanying
Sheet of Drawings.

page_text: while the bearings E of the bottom roller B are fitted so as to slide freely
in the framework C, and are adjustable in the direction of the upper
roller A.
The means employed for adjusting the bottom roller B are as follows:
-I mount two levers F and G on a carrier H fixed between the frame t
C. The short ends i and j of these levers are brought under the
adjustable bearings or bushes E of the lower roller B, and connected
therewith by rods K, the long ends and m of the levers are brought to
the centre of the machine at which point the levers are acted upon by a
spiral spring O which works against a boss P on the carrier H through 1
which boss P a rod q is passed and connected to the long ends of the
levers F and G, as shewn at r, the other end of the rod q is passed
through the bottom of the boss P and on it is screwed a hand wheel S,
the boss of which serves as an adjusting nut which operates against the
spring. By turning the hand wheel S the required pressure is trans- 1
mitted from the spring through the rod to which the long ends of the
levers F and G are attached, and thence to the rollers.

page_text: First. The arrangement, construction, and application of levers F
and G, and the parts connected therewith for adjusting the rollers
A and B, substantially as herein set forth.
Second. The arrangement and combination of the various parts
forming the machine, substantially as and for the purposes herein
set forth.
In witness whereof, I, the said George Pigott, have hereunto set
my hand and seal, this Twenty-fourth day of March, in the
year of our Lord One thousand eight hundred and seventy-three.
