IMPROVEMENTS IN SEWING MACHINES."
Year: 1874

page_text: LETTERS PATENT to Arthur Chapman and Samuel George Sutton,
both of Limehouse, in the County of Middlesex, for the Invention
of "IMPROVEMENTS IN SEWING MACHINES."
PROVISIONAL SPECIFICATION left by the said Arthur Chapman and
Samuel George Sutton at the Office of the Commissioners of
Patents, with their Petition, on the 14th April 1874.
We, ARTHUR CHAPMAN and SAMUEL GEORGE SUTTON, both of
Limehouse, in the County of Middlesex, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN SEWING MACHINES," to be as
follows:-
These improvements relate more especially to the sewing machine for
which Letters Patent have been granted to Fenner Ballon Taylor,
bearing date the 4th day of April 1873, No. 1266, parts of the said
improvements being applicable to other sewing machines.
The said improvements consist in an improved four-motion feeding ¨

page_text: improved method of imparting the lateral motion to the rod which
operates the feed bar and looper.
In our improved feeding device the feed bar has its fulcrum at its
forward end. The said feed bar is raised by a lever at the back of the
machine, the said lever being operated by a cam on the spindle of the
driving wheel. The backward throw of the feed bar is effected by
the rod which operates the looper. At the completion of the backward
throw the said feed bar is released from the pressure of the said lever
and falls by gravity, the forward or return movement being effected by
a spiral spring or equivalent device.
Our improved device for holding the cotton consists of a small spiral
spring around that portion of the needle bar which is above the frame
of the machine, the said spring being held by a clamp fitting around
the top of the said spring and under the frame of the machine. The
needle bar is provided with a head or cap having a projecting cyclet.
The cotton passes through a hole in the needle bar immediately under
the head and thence through the said cyclet to the needle. When the
needle bar has completed its downward stroke it presses the said spiral
spring and clamp down upon the frame of the machine and holds the
cotton between the head of the needle bar and the said clamp.
Instead of a slotted plate for imparting the lateral movement to the
rod which operates the looping and feeding devices we employ a link
pivotted at one end to the said rod and at the other end to the frame of
the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Arthur Chapman and Samuel George Sutton in
the Great Seal Patent Office on the 12th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ARTHUR
CHAPMAN and SAMUEL GEORGE SUTTON, both of Limehouse, in the
County of Middlesex, send greeting.
:
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

page_text: and grant unto us, the said Arthur Chapman and Samuel George Sutton
Her special license that we the said Arthur Chapman and Samuel George
Sutton, our executors, administrators, and assigns, or such others as we,
the said Arthur Chapman and Samuel George Sutton, 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 Ircland the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
SEWING MACHINES," upon the condition (amongst others) that we, the
said Arthur Chapman and Samuel George Sutton, our exccutors or
administrators, by an instrument in writing under our, or their, or onc
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 Chapman and Samucl
George Sutton, do hereby declare the nature of the 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 Drawing forming a part of this
Specification :-
These improvements relate more especially to the sewing machino for
which Letters Patent have been granted to Fenner Ballon Taylor,
bearing date the Fourth day of April A.D. 1873, No. 1266, parts of the
said improvements being applicable to other sewing machines.
The said improvements consist in an improved four-motion feeding
device, a device for holding the thread while cach stitch is made, and an
improved method of imparting the lateral motion to the rod which
operates the feed bar and looper.
In our improved feeding device the feed bar has its fulcrum at its
forward end. The said feed bar is raised by a lever at the back of the
machine, the said lever being operated by a cam on the spindle of the
5 driving wheel. The backward throw of the feed bar is effected by
the rod which operates the looper. At the completion of the backward
throw the said feed bar is released from the pressure of the said lever and

page_text: falls by gravity, the forward or return movement being effected by a
spiral spring or equivalent device.
Our improved "take up" or device for holding the cotton consists of
a small spiral spring around that portion of the needle bar which is
above the frame of the machine, the said spring being held by a clamp a
fitting around the top of the said spring and under the frame of the
machine. The needle bar is provided with a head or cap having a
projecting eyelet or hook. The cotton passes through a hole in the
needle bar immediately under the head, and thence through the said
cyelet or over the said hook to the needle. When the needle bar has 1
completed its downward stroke it presses the said spiral spring, and
clamp down upon the frame of the machine and holds the cotton
between the head of the needle bar and the said clamp.
Instead of a slotted plate for imparting the lateral movement to the
rod which operates the looping and feeding devices we employ a link 1
pivotted at one end to the said rod and at the other end to the frame
of the machine.

When the needle bar has completed its downward stroke the cotton
is held between the head of the needle bar and the ring g of the
clamp G.
The device for imparting a lateral movement to the rod D consists of
a link I (see Figure 1), the said link being pivotted at one end to the
said rod and at the other end to the frame of the machine.
In witness whereof, we, the said Arthur Chapman and Samuel
George Sutton, have hereunto set our hands and scals, this
Eighth day of October, in the year of Lord One thousand cight
hundred and seventy-four.
