Year: 1871

page_text: LETTERS PATENT to John Edward Woodhouse, of Farsley, near
Bradford, and William Chaffer, of Holbeck, near Lecds, both in
the County of York, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR CLEARING, DRAWING, TWISTING, AND SPINNING WOOL,
COTTON, SILK, AND OTHER FIBROUS SUBSTANCES."
Sealed the 31st October 1871, and dated the 5th May 1871.
PROVISIONAL SPECIFICATION left by the said John Edward Wood-
house and William Chaffer at the Office of the Commissioners of
Patents, with their Petition, on the 5th May 1871.
We, JOHN EDWARD WOODHOUSE, of Farsley, near Bradford, and
WILLIAM CHAFFER, of Holbeck, ncar Leeds, both in the County of York,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR CLEARING, DRAWING, TWISTING, AND SPINNING WOOL, COTTON,
SILK, AND OTHER FIBROUS SUBSTANCES," to be as follows:-
Our Invention consists of a machine arranged in such manner in
connection with doffers of condensers, cards, and other similar machines
that the material is cleared therefrom by means of a porcupine stripper
and afterwards drawn, twisted, and spun, all as hereafter described. On

page_text: framework in connection with the condenser, card, or other similar
machine, we mount a porcupine stripper running parallel with the
doffer, and so near thereto as to clear or strip it of the material collected
upon it. The stripper revolving carries the material round to another by
the assistance of a trough or guide through which a steam pipe is passed
for the purpose of warming the material. The first stripper is then
relieved of the material taken from the doffer by the second stripper
from which it is conducted into a trumpet or twister by fingers or guides.
The trumpet or twister is made to revolve at a suitable speed and is of
such a form as to twist the material as it passes through. After under-
going this operation the material passes between drawing rollers, thence
through various guides or conductors to the bobbins or cops which are
mounted on spindles and are made to revolve in the ordinary manner. A
weight may be hung on the thread between the guides or conductors
to give the necessary tension. The porcupine strippers are made by
preference of brass, but other metal may be used into which steel pins
are inserted and fixed of a suitable pitch or distance apart.
Strippers constructed in this manner may also be used independently
of the spinning and twisting arrangement, and applied to condensers,
cards, and other similar machines of ordinary construction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Edward Woodhouse and William Chaffer in
the Great Seal Patent Office on the 3rd November 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
EDWARD WOODHOUSE, of Farsley, near Bradford, and WILLIAM
CHAFFER, of Holbeck, near Leads, both in the County of York, send
greeting.

fourth year of Her reign, did, for Herself, Her heirs and successors;
give and grant unto us, the said John Edward Woodhouse and William
Chaffer, Her special licence that we, the said John Edward Woodhouse
and William Chaffer, our executors, administrators, and assigns, or such
others as we, the said John Edward Woodhouse and William Chaffer,

page_text: our 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 "IM-
PROVEMENTS IN MACHINERY FOR CLEARING, DRAWING, TWISTING, AND SPINNING
WOOL, COTTON, SILK, AND OTHER FIBROUS SUBSTANCES," upon the condiţion
(amongst others) that we, the said John Edward Woodhouse and
William Chaffer, our executors or administrators, by an instrument in
writing under our or their, or one of their hands and scals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the samo
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 we, the said John Edward Woodhouse and
William Chaffer, do hereby declare the nature of our said Invention
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof,
reference being had to the accompanying Drawings, and to the letters
of reference marked thereon, that is to say :-
Our Invention consists of a machine arranged in such manner in
connection with doffers of condensers, cards, and other similar machines
that the material is cleared therefrom by means of a porcupine stripper,
and afterwards drawn, twisted, and spun, all as hereafter described.
On framework in connection with the condenser, card, or other similar
machine, we mount a porcupine stripper running parallel with the
doffer, and so near thereto as to clear or strip it of the material collected
upon it. The stripper revolving carries the material round to another
by the assistance of a trough or guide through which a steam pipe is
passed for the purpose of warming the material. The first stripper is
then relieved of the material taken from the doffer by the second
stripper from which it is conducted into a trumpet or twister by fingers
or guides. The trumpet or twister is made to revolve at a suitable
speed, and is of such a form as to twist the material as it passes through.
After undergoing this operation the material passes between drawing
rollers, thence through various guides or conductors to the bobbins or
cops which are mounted on spindles, and are made to revolve in the
ordinary manner. A weight may be hung on the thread between the

page_text: guides or conductors to give the necessary tension. The porcupine
strippers are made by preference of brass, but other metal may be used
into which steel pins are inserted and fixed of a suitable pitch or
distance apart.
Strippers constructed in this manner may also be used independently
of the spinning and twisting arrangement and applied to condensers,
cards, and other similar machines of ordinary construction.
Figure 1 shows a transverse section, and Figure 2 a plan of machinery
made according to our Invention.
a is the framework; 6 the porcupine stripper running parallel with
the doffer c, and so near thereto as to clear or strip it of the material
collected upon it as shown at d. The stripper 6 revolving carries the
material round to another stripper e, by the assistance of a trough or
guide through which steam may be passed for the purpose of warming
the material. The strippers by means of pinions are geared with each
other, motion being transmitted to them by means of a spur wheel on
the doffer shaft gearing into the pinion on the stripper. The first
stripper a is then relieved of the material taken from the doffer c by
the second stripper e from which it passes into an adjustable trumpet
or twister g. When necessary fingers or guides may be used between
the twister and the stripper e to conduct the material off the second
stripper e. The trumpet or twister 9 is made to revolve at a suitable
speed, motion being transmitted thereto by means of the bands or
straps from the cylinder i which is mounted in suitable bearings on
the framework in the same manner as on spinning frames of ordinary
construction. Additional strippers may be used between the twister g
and stripper e. By the rotary motion of the twister or trumpet the
material is twisted as it passes through. The amount of twist may
bo of course varied by increasing or diminishing the number of
revolutions of the trumpet or twister. After undergoing the above
described operations the material passes between the drawing rollers j, j
of ordinary construction. Motion is given to the rollers j, j, from the
stripper shaft k, as shown, suitable change and intermediate wheels
being employed for transmitting it, whereby the draft may be altered
as may be required. The supports 1, 2, carrying the drawing rollers
are made adjustable, being provided with slot holes m, m, on the
framework, so that the length of reach may be altered between the
drawing rollers j,j, and trumpets or twisters g, y, to suit the various

page_text: t
kinds of material operated upon. .The material passes from the drawing
rollers through the guides n, n, over the rollers o, o, thence through
the guides p, and on to the bobbins or cops q, which are mounted on
spindles r,, of ordinary construction, motion being conveyed thereto
from the cylinder i by means of the bands or straps & in the usual manner
employed on spinning frames. A weight may be suspended, as shown
on the thread to give the required amount of tension. The porcupine
strippers c and b, shown in Figures 3 and 4, are made, by preference, of
brass, but other metal may be used, and are threaded on the shafts j,
and held or pressed together by means of the nuts u, u, which may be
tightened at each end of the shafts. Steel pins are inserted in the
strippers as before described.
Having now described the nature of the said Invention, and in what
manner the same is to be performed, we declare that we do not limit
ourselves to the exact details or configuration of the parts explained
and shown, as the same may be varied without departing from the nature
of the Invention, but what we claim and desire to be secured to us by
Letters Patent arc,-
Firstly. The arrangement, construction, and combination of parts
forming machinery in connection with doffers of condensers, cards, or
other similar machines, whereby the material is cleared therefrom and
afterwards drawn, twisted, and spun, all substantially as herein-before
described and illustrated in the accompanying Drawings.
Secondly. The construction, arrangement, and application of the
porcupine strippers in connection with the doffers of condensers,
cards, or other similar machines, substantially as and for the purposes
set forth.
In witness whercof, we, the said John Edward Woodhouse and
William Chaffer, have hereunto set our hands and scals, the
