IMPROVE- WADA Mina un VADE IN REEDERS
Year: 1863

page_text: LETTERS PATENT to James Isherwood, of Sharples, near Bolton, in the
County of Lancaster, Yarn Bleacher, for the Invention of "IMPROVE-
WADA Mina un VADE IN REEDERS"
PROVISIONAL SPECIFICATION left by the said James Isherwood at the
Office of the Commissioners of Patents, with his Petition, on the
9th March 1863.
I, JAMES ISHERWOOD, of Sharples, near Bolton, in the County of Lancaster,
Yarn Bleacher, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN WORKING PRESSES FOR MAKING UP YARN IN BUNDLES," to be
as follows:-
The presses hitherto employed in making up yarn in bundles have been
worked by a rack and pinion actuated by manual labor or by power; now my
Invention consists in giving the requisite pressure to the yarn by the direct.
action of hydraulic power or steam. In performing my Invention a ram is
attached to the follower of the press, and this ram fits in a cylinder in commu-
nication with the water or steam pipe, which is furnished with inlet and outlet
equilibrium valves. When the yarn to be pressed is placed on the follower,
and the top and sides of the press are secured in the usual manner, water or
steam is admitted to the cylinder, and the follower is gradually raised until the
yarn is sufficiently compressed; a self-acting or other stop connected to the
follower then comes into operation, and by closing the inlet valve shuts off the

page_text: valve or steam by which the follower is raised; the bundle of yarn is then
corded in the usual manner, and the outlet valve is opened to allow the
follower to descend for the subsequent operation.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Isherwood in the Great Seal Patent Office on the
Sth September 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
ISHERWOOD, of Sharples, near Bolton, in the County of Lancaster, Yarn
Bleacher, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of March, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said James Isherwood, Her special license that I, the said James
Isherwood, my executors, administrators, and assigns, or such others as I,
tho said James Isherwood, 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 WORKING PRESSES FOR MAKING UP YARN IN BUNDLES,"
upon the condition (amongst others) that I, the said James Isherwood, 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 per-
formed, 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 James Isherwood, do hereby declare
the nature of my 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, that is to say):-
The presses hitherto employed in making up yarn in bundles have been
worked by a rack and pinion actuated by manual labour or by power; now
my Invention consists in giving the requisite pressure to the yarn by the direct
action of hydraulic power or steam. In performing my Invention a ram is

page_text: attached to the follower of the press, and this ram fits in a cylinder in commu-
nication with the water or steam pipe, which is furnished with inlet and outlet
valves, either equilibrium or otherwise. When the yarn to be pressed is
placed on the follower and the top and sides of the press are secured in the
usual manner, water or steam is admitted to the cylinder, and the follower is
gradually raised until the yarn is sufficiently compressed; a self-acting or other
stop connected with the follower then comes into operation, and by closing the
inlet valve shuts off the water or steam by which the follower is raised; the
bundle of yarn is then corded in the usual manner, and the outlet valve is
opened to allow the follower to descend for the subsequent operation.
And in order that my Invention may be fully understood and readily carried
into effect, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Figure 1 is a side elevation of a press for making up yarn in bundles to
which my improvements are applied; and Figure 2 is a front view of the
same.
a, a, are the standards, and 6 the table to which the press is fixed. The
press is similar to those now in use. c is the follower, to which are attached
the guide rods c, c', and the ram d fitting in the cylinder e, to which steam or
water under pressure is admitted through the pipef; 9 is the inlet tap or
valve; h, the outlet tap or valve; and i, the off pipe. These taps are opened
and closed by the handles g¹ and h'. When the hanks of yarn have been laid
on the follower c, and the side bars and top bars have been secured in the
usual manner, the handle g' is turned to admit the steam or water to the
cylinder e, the pressure thus brought on the ram d raises it until the lock
nuts on the guide rods c¹ come in contact with the under side of the cross
rail a', which connects the two standards a, a; the valve g is then closed and
the bundle of yarn is corded in the usual manner. The outlet valve h is then
opened to discharge the steam or water from the cylinder, thus allowing the
ram and follower to descend for the subsequent operation.
Figures 3 represents a modification of my Invention. In this instance the
valves g and h are equilibrium valves, and the admission valve 9 is self-acting
by means of the shoulder on the guide rod c', which shoulder, when the
follower has risen to the proper height for compressing the bundle of yarn,
comes in contact with the projection 92, and by raising this projection depresses
the lever g³, which passes through the valve spindle and closes the valve at the
proper time. The off valve h is opened and closed by the handle h¹, as in
Figures 1 and 2.
By means of these improvements great economy in labor is effected, and the

page_text: presses, which are generally placed side by side on a long table, can be
worked much more expeditiously than heretofore.
Having thus stated the nature of my Invention, and described two con-
venient modes of performing the same, I wish it to be understood that various
modifications in the details may be made without departing from the peculiar
character of the Invention, and I declare that claim the use and application
of steam and water under pressure for working presses for making up yarn
in bundles.
In witness whereof, I, the said James Isherwood, have hereto set my
hand and seal, this Fourth day of September, in the year of our
Lord One thousand eight hundred and sixty-three.
JAMES ISHERWOOD. (L.S.)
