Year: 1855

page_text: LETTERS PATENT to William Mosley, of Salford, in the County of Lan-
caster, Bleacher, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR STRETCHING AND FINISHING WOVEN FABRICS."
Sealed the 30th May 1856, and dated the 6th December 1855.
PROVISIONAL SPECIFICATION left by the said William Mosley at the
Office of the Commissioners of Patents, with his Petition, on the 6th
· December 1855.
I, the said WILLIAM MOSLEY, do hereby declare the nature of the said
Invention for IMPROVEMENTS IN MACHINERY OR APPARATUS FOR STRETCHING AND
FINISHING WOVEN FABRICS, to be as follows:-
My improvements relate to a method of treating woven fabrics upon the
principle of callendering, that is to say, the goods are caused to be operated
upon by one or more rollers acting against other surfaces.
According to my Invention, I so construct one or more of these rollers that
their peripheries are provided with spiral projections or channels which act
against the goods.
According to another part of my Invention, I employ the aforesaid spiral or
ordinary plain rollers, and impart thereto a reciprocating motion by means of
excentrics or other such apparatus..

by the said William Mosley in the Great Seal Patent Office on the
6th June 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MOSLEY, of Salford, in the County of Lancaster, Bleacher, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of December, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Mosley, Her especial license that I, the said William Mosley, my
executors, administrators, and assigns, or such others as I, the said William
Mosley, 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 MACHINERY
OB APPARATUS FOR STRETCHING AND FINISHING WOVEN FABRICS," upon the con-
dition (amongst others) that I, the said William Mosley, by an instrument
in writing under my hand and seal, should particularly describe and ascer-
tain 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 William Mosley, 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 and accompanying Drawings (that is to say):-
My improvements relate to a method of treating woven fabrics upon the
principle of callendering, that is to say, the goods are caused to be operated
upon by one or more rollers acting against other surfaces.
And in order that my Invention may be fully understood, I have appended
to this my complete Specification a Sheet of Drawings illustrative of the same;
Fig. 1 being a sectional end view of a machine shewing the application of my
Invention; and Fig. 2 is a side view of the same.
The framework is at a, having a slot 6 formed in it as a guide for the
bearings of the rollers, the lower one of which is at c, mounted in suitable
bearings, and having right and left handed spiral channels or projection
formed on its periphery, and which receives its motion from any ordinary

page_text: motive power by means of the spur wheel, mounted upon the end of the
shaft d. The plain roller upon which the cloth or fabric is to be wound
is at e, guided in bearings by the slot b, and, resting upon the roller c,
aforesaid, receives its motion by the friction of contact. f is the top roller,
also having right and left handed spiral channels or projections formed upon
it, and caused to revolve by being in contact with the central or plain
roller c. The roller f is caused to rise by means of the increasing diameter
of the roller e, aforesaid, when the cloth or fabric is wound on it, and carries
with its bearings the block piece g and the rack h, the upward motion of
which will cause the pinion i, fast upon the shaft j, to revolve in the direc-
tion shewn by, the arrow; upon the shaft j is also fixed the spur wheel k, taking
into the pinion 1, fast upon the shaft m, upon one end of which is also fixed the
friction pulley or brake wheel n, around the periphery of which the clip o is
passed, one end being attached to the framework at p, the lower end being
secured by means of a joint and pin to the weighted lever q, the fulcrum of which
is at ; the weighted lever q, acting by means of the friction clip upon the
pulley, will have a tendency to prevent the shaft m from revolving, and will,
consequently, by means of the pinion i and rack h, retard the raising of the spiral
grooved roller f, the required amount of pressure upon which being regulated
by adding additional weight to the lever q, and vice versa. When it is required
to remove the central or cloth roller e, for the purpose of taking off the piece,
&c., the top roller f may be raised or wound up by means of the hand wheel s
fast upon the shaft m, the same being retained in the required position by
means of the ratchet wheel t and click t*. The rollers cand f, having the spiral
channels or projections formed upon them, receive a reciprocating motion when
revolving by means of the cams u and u, mounted upon the shafts d and d
moving in the fixed parts y and y, to reduce the friction of which, pulleys a
and are used, turning upon suitable centres. The cloth or fabric being
previously wound on the roller w, is transferred from it in the direction indi-
eated by the red line over the stave beams or rollers v, on to the central plain
roller e, as aforesaid.
It will be seen, on reference to the Drawing, that the top and bottom rollers,
having right and left handed spiral channels or grooves formed upon their
peripheries, will, when revolving, cause the cloth or woven fabric to be stretched
in the direction shewn by the arrows, and from their reciprocating motion the
cloth may be finished, and receive a lustre to the required extent. If it be
desirable, portions of the spiral projections may be cut away, thus forming
intermediate plain spaces; or, in place of one of the grooved rollers, above
mentioned, a plain roller receiving a reciprocating motion may be used; and

page_text: instead of the arrangement shewn for weighting the roller f, levers and weights
may be adapted to produce the same effect.
Having thus described and ascertained the nature of my Invention, and
the manner in which it is to be performed, I desire it to be understood
that I claim, as secured to me under the above in part recited Letters
Patent,
Firstly, the use, for the purpose set forth above, of rollers having spiral
channels or projections formed upon their peripheries; and also imparting a
reciprocating motion to the rollers above described.
In witness whereof, I, the said William Mosley, have hereunto set
my hand and seal, this Fifth day of June, in the year of our Lord
One thousand eight hundred and fifty-six,
