IMPROVEMENTS IN SEWING MACHINES
Year: 1871

page_text: LETTERS PATENT to Arthur Nussey, Altham Pilling, and Cyrias
Henry Hall, all of Leeds, in the County of York, for the Invention
of "IMPROVEMENTS IN SEWING MACHINES."
Sealed the 16th January 1872, and dated the 23rd November 1871.
PROVISIONAL SPECIFICATION left by the said Arthur Nussey,
Altham Pilling, and Cyrias Henry Hall at the Office of the Com-
missioners of Patents, with their Petition, on the 23rd November
1871.
We, ARTHUR NUSSEY, ALTHAM PILLING, and CYRIAS HENRY HALL,
all of Leeds, in the County of York, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN SEWING MACHINES," to be as
follows:-
-
Our improvements have reference to those sewing machines known
as the "Wheeler and Wilson" machines, and are as follows:-
First. Instead of the needle hole or slot in the cloth plate being
straight as hitherto, and with its sides parallel, we employ either a

page_text: curved slot or one taper in its length, that is to say, wider at one end
than the other. When constructed of a curved form that curve must
be of a similar form to the curve of the relief on the rotating hook used
in these machines. If the slot is constructed of a taper form it must
be of such dimensions as to allow the thread to pass freely round the
rotating hook. By these arrangements of slots or needle holes the
thread is enabled to pass more freely round the rotating hook, whereby
material of variable thicknesses may be sewn without varying the
tension, at the same time the frequent breaking of the thread is pre-
vented hitherto attending the working of these machines. The operator
may also turn the material in any required direction without either
breaking the thread or leaving a loop or imperfect stitch. In order
to facilitate the working of these machines and better adapt them to
the various sizes of thread we fit in the cloth plate a plate which is
made reversible, the sides of it being made to form a portion of the
needle slot. By reversing this plate the slot may be made larger or
smaller to suit the various sizes of thread.
Secondly. Our improvements apply to the slide ring. In order that
the needle thread may more easily pass over the spool containing the
second or locking thread (after the needle thread has passed the loop
check) that portion of the slide ring known as the "relief" is cut
away considerably more at the top than at the bottom so as to allow
the loop to pass from the loop check without friction. By this arrange-
ment all the various sizes of thread may be used without altering the
slide ring or loop check.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Arthur Nussey, Altham Pilling, and Cyrias
Henry Hall in the Great Seal Patent Office on the 1st February
1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ARTHUR 3
NUSSEY, ALTHAM PILLING, and CYRIAS HENRY HALL, all of Leeds, in
the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of November, in

page_text: the year of our Lord One thousand eight hundred and seventy-one,
in the thirty-fifth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said Arthur Nussey, Altham
Pilling, and Cyrias Henry Hall,. Her special licence that we, the
said Arthur Nussey, Altham Pilling, and Cyrias Henry Hall, our exe-
cutors, administrators, and assigns, or such others as we, the said
Arthur Nussey, Altham Pilling, and Cyrias Henry Hall, our exccutors,
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
SEWING MACHINES," upon the condition (amongst others) that we, the
said Arthur Nussey, Altham Pilling, and Cyrias Henry Hall, our
executors or administrators, by an instrument in writing under our,
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 we, the said Arthur Nussey, Altham Pilling,
and Cyrias Henry Hall, 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,
reference being had to the accompanying Drawings, and to the letters
of reference marked thereon, that is to say :-
Our improvements have reference to those sewing machines known
as the "Wheeler and Wilson" machines, and will be best understood
by reference to the accompanying Drawings.
Figs. 1, 2, 3, 4, and 5 show the first, and Figs. 6, 7, and 8. the second
part of our Invention.
First. Instead of the needle hole or slot in the cloth plate, Fig. 1,
being straight as hitherto and with its sides parallel we employ either
a curved slot, as shown in Fig. 1, or one tapered in its length, as shewn
in Fig. 4, that is to say, wider at one end than the other. When con-
structed of a curved form; as shown at a in Fig. 1, that curve must be

page_text: of a similar form to the curve of the relief 6 on the rotating hook,
Fig. 5, used in these machines. If the slot is constructed of a taper
form, as shewn at c, Fig. 4, it must be of such dimensions as to allow
the thread to pass freely round the rotating hook, Fig. 5. By this
arrangement of slots or needle holes the thread is enabled to pass more
freely round the rotating hook, whereby material of variable thicknesses
may be sewn without varying the tension, at the same time preventing
the frequent breaking of the thread hitherto attending the working of
these machines. The operator may also turn the material in any
required direction without either breaking the thread or leaving a loop
or imperfect stitch. In order to facilitate the working of these
machines, and better adapt them to the various sizes of thread, we fit
in the cloth plate a plate d which is made reversible, each side e and
f forming a portion of the needle slot a, Fig. 1. By reversing this
plate the slot may be made larger or smaller to suit the various sizes of
thread.
Secondly. Our improvements apply to the slide ring. In order that
the needle thread may more easily pass over the spool containing the
second or locking thread (after the needle has passed the loop check)
that portion of the slide known as the relief is cut away considerably
more at the top g than at the bottom h, as shewn in Figs. 6, 7, and 8,
so as to allow the loop to pass from the loop check without friction.
Whereas in machines of ordinary construction the relief is cut away
parallel with the back part i. By this arrangement all the various
sizes of thread may be used without altering the position of the slide
ring or loop check.
Having now described the nature of our said Invention, and the
manner in which the same is to be performed, we would remark in
. conclusion that we do not limit ourselves to the exact details, limits,
and configuration of parts we have described and shewn, as the same
may be varied or modified without in any way departing from our
Invention; but what we do claim and desire to be secured to us by
Letters Patent are,-
Firstly. The arrangement, construction, and application of a taper or
curved needle hole or slot with reversible plate, substantially as and

page_text: Secondly. The arrangement, construction, and application of that
part of the slide ring known as the relief, substantially as and for the
purposes herein set forth.
In witness whereof, we, the said Arthur Nussey and Cyrias Henry
Hall, for ourselves and on behalf of the said Altham Pilling,
have hereunto set our hands and seals, this Twenty-ninth day of
January, in the year of our Lord One thousand eight hundred
and seventy-two.
