CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DOUBLING YARNS OF COTTON OR OTHER FIBROUS MATERIALS
Year: 1860

page_text: LETTERS PATENT to John Schofield, of Oldham, in the County of Lancaster,
Machinist, and Miles Schofield, of the same Place, Machine Joiner,
for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR DOUBLING YARNS OF COTTON OR OTHER FIBROUS MATERIALS."
Sealed the 26th April 1861, and dated the 15th November 1860.
PROVISIONAL SPECIFICATION left by the said John Schofield and Miles
Schofield at the Office of the Commissioners of Patents, with his Petition,
on the 15th November 1860.
We, JOHN SCHOFIELD, of Oldham, in the County of Lancaster, Machinist,
and MILES SCHOFIELD, of the same Place, Machine Joiner, do hereby declare
the nature of the said Invention for "CERTAIN IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR DOUBLING YARNS OF COTTON AND OTHER FIBROUS MATERIALS,"
to be as follows:-
Our Invention relates to the well-known machines employed in the above
process called twiners or twisters, and consists in an improved arrangement of
mechanism or apparatus for the purpose of holding or retaining the threads
whilst being wound on to the spindles.
In performing our Invention we make use of the ordinary grooved rail
forming the lower jaw, but in some cases instead of making this lower jaw of
wood, as now customary, we make it of metal, and we make the upper
jaw of short pieces of brass, or other metal or material; these upper jaws are

page_text: opened and closed by the usual mechanism to release and to hold the threads,
which can be passed between the ends of these short pieces, thereby affording
great facility in working the machine.
Another part of our Invention consists in applying a hand rail to the
carriage of twiners or twisters for the operative to rest upon when leaning
forward to piece up the ends.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Schofield and Miles Schofield in the Great Seal Patent
Office on the 9th May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Jonn
SCHOFIELD, of Oldham, in the County of Lancaster, Machinist, and MILES
SCHOFIELD, of the same Place, Machine Joiner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of November, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Schofield and Miles Schofield, Her special licence, that we, the
said John Schofield and Miles Schofield, our executors, administrators, and
assigns, or such others as we, the said John Schofield and Miles Schofield,
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 "CERTAIN IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR DOUBLING YARNS OF COTTON OR OTHER FIBROUS
MATERIALS," upon the condition (amongst others) that we, the said John
Schofield and Miles Schofield, our executors or administrators, by an
instrument in writing under our, or their, or one of our or 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 we, the said John Schofield and Miles Schofield,
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 (that is to say) :-

page_text: Our Invention relates to the well-known machines employed in the
operation of doubling yarns called twiners or twisters, and it consists in
an improved arrangement of mechanism or apparatus for the purpose
of holding or retaining the threads whilst being wound on to the
spindles.
In performing our Invention we make use of the ordinary grooved rail
forming the lower jaw, but in some cases instead of making the lower jaw
of wood, as now customary, we make it of metal, and we make the upper jaw
of short pieces of brass or other metal or material; these upper jaws are opened
and closed by the usual mechanism to release and to hold the threads, which
can be passed between the ends of these short pieces, thereby affording great
facility in working the machine.
Another part of our Invention consists in applying a hand rail to the
carriage of twiners or twisters for the operative to rest upon when leaning
forward to piece up the ends.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the accompanying Sheet
of Drawings, reference being had to the figures and letters marked
thercon.
Figure 1 is an elevation of the principal parts of a doubling machine called
a twiner or twister, to which our improvements are applied; Figure 2 is a
plan of part of the same; Figure 3 is an edge view; and Fig. 4 is plan of our
improved holder or upper jaw.
In Figure 1, a is the frame of the machine which may be of any convenient
shape; b, the rail on which the carriage c moves to and fro; d, d, are the
skewers on which the cops of yarn to be doubled are mounted; and e, the
spindles on which the doubled yarn is wound. These parts and all the others
which are not shewn in the Drawings, or not particularly referred to hereafter,
but which are requisite to complete the machine, are made in the usual
manner; fis the grooved rail forming the lower jaw of the holder; this rail
may either be of wood, as now customary, or of metal. The upper jaw consists
of the pieces g, shewn in Figures 3 and 4; we prefer to make these jaws about
three inches long or of the requisite length to act on two threads; as shewn in
Figure 2, but we do not limit ourselves to this length, the jaws g are secured
to a rail h, which is suspended by the rods i to the levers j, fixed to the shaft or
hand rail, which extends the whole length of the carriage c, and serves as a
support to the attendant when leaning over the carriage to piece up an
end; to the shaft is also fixed the lever 1, which is acted upon
in the usual manner, when the carriage is out aud in, to open and close the

page_text: jaws. The upper jaws 9 are a little distance apart to enable the operator
to pass the threads between their ends when a breakage takes place.
The mode of operation is as follows:-The Drawing represents the jaws
closed, and the carriage is supposed to be running in towards the spindles c, on
which the doubled yarn is being wound; as soon as the carriage arrives near
these spindles, the lever l, coming against the usual projection, opens the
jaws or holders g, to allow a fresh length of yarn to be drawn off tho
cops d, d.
Having thus described the nature of our Invention, and the manner of per-
forming the same, we declare that we claim,-
First, the making the grooved rail f constituting the lower jaw of twiners or
twisters of metal instead of wood, as now customary.
Secondly, the making the upper jaw g of short pieces of metal or other
material, as shewn and described.
And, thirdly, the application of a hand rail to the carriage of twiners or
twisters, as shewn and described.
In witness whereof, I, the said Miles Schofield, have hereunto set my
hand and seal, the Seventh day of May, in the year of our Lord
One thousand eight hundred and sixty-one.
MILES SCHOFIELD. (L.S.)
