page_text: LETTERS PATENT to William Jackson, of 1", Caroline Street, Eaton
Square, Pimlico, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN SEWING OR STITCHING MACHINES FOR SEWING THE SOLES
OF BOOTS AND SHOES.".
Scaled the 28th August 1874, and dated the 16th June 1874.
PROVISIONAL SPECIFICATION left by the said William Jackson at
the Office of the Commissioners of Patents, with his Petition, on
the 16th June 1874.
I, WILLIAM JACKSON, of 1ª, Caroline Street, Eaton Square, Pimlico,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SEWING OR STITCHING MACHINES FOR SEWING
THE SOLES OF BOOTS AND SHOES," to be as follows:-
-
My Invention consists in a novel construction and arrangement of
parts of a sewing or stitching machine to form a chain or loop stitch to
work with wax thread, and an arrangement for waxing the thread
during the operation of stitching, which is accomplished by the wax pot
placed under the machine, which keeps the wax hot and also the

page_text: machine. The stitch is produced by an improved looper dispensing
with the whirl commonly used for that purpose in combination with an
arm which is for the purpose of working in connection with a hook or
barbed needle, and passing the thread into the hook of the needle. It is
actuated by means of a cam with a slot or groove in it, made of
suitable form, working in connection with a pin and roller and driven
from the main shaft of the machine by means of an excentric motion
for passing the thread into the hook. This arrangement of looper is
much simply, cheaper, and not so liable to get disarranged nor so liable
to break needles as machines now in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said William Jackson in the Great Seal Patent Office
on the 12th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JACKSON, of 1º, Caroline Street, Eaton Square, Pimlico, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Jackson, Her special licence
that I, the said William Jackson, my exccutors, administrators, and
assigns, or such others as I, the said William Jackson, 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 SEWING OR STITCHING MACHINES FOR SEWING THE SOLES OF BOOTS AND
SHOES," upon the condition (amongst others) that I, the said William
Jackson, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same

page_text: 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 Jackson, 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 :-
My Invention consists in a novel construction and arrangement of
parts of a sewing or stitching machine to form a chain or loop stitch to
work with wax thread, and an arrangement for waxing the thread during
the operation of stitching, which is accomplished by the wax pot placed
under the machine, which keeps the wax hot and also the machine.
The stitch is produced by an improved looper, dispensing with the whirl
commonly used for that purpose, in- combination with an arm, which is
for the purpose of working in connection with a hook or barbed needle
and passing the thread into the hook of the needle. It is actuated by
means of a cam with a slot or groove in it, made of suitable form,
working in connection with a pin and roller, and driven from a main
shaft of the machine by means of an eccentric motion for passing the
thread into the hook. This arrangement of looper is much simpler,
cheaper, and not so liable to get disarranged nor so liable to break
needles as machines now in use.
The nature of the said Invention consists first in the arrangement for
waxing the thread and keeping the wax hot and heating the machine
by the same heat that melts the wax. This is accomplished by placing
the wax pot within a hollow pedestal, where a much harder wax can be
used than hitherto, and a great saving of time, as it can be worked
from a ball of thread instead of having to be wound on a bobbin. The
tension is produced by passing the thread betwixt two washers, or
by other ways, passing it once round a pulley working in centres,
and having an adjustable screw for the purpose of giving the required
tension.
My Invention further consists of a looper spindle or thread conductor,
and arrangement for working the same in combination with an arm
for sewing the soles of boots and shoes, substantially as hereafter
described.

page_text: arrangement of parts for sewing on the soles of boots and shoes to
be as follows, and consist in the construction of a machine in a more
simple and efficient manner than has hitherto been done for the purpose
above mentioned.
The accompanying Drawings shew the parts generally composing this
machine, the same letters and figures of reference referring to liko
parts throughout.
Figure 1 is a side elevation of the machine; Figure 2 is a front
elevation; Figure 3 is a side view of the horn or arm; Figure 4 repre-
sents a plan view of Fig. 3.
Referring to Figure 1 A is the main shaft running in suitable
bearings at 5, 5, and may be driven by any convenient method. To the
main shaft A is attached the disc B, one face of the disc, which is of
suitable form to work or propel the plate K by means of a roller and
pin Lattached thereto. The plate K is attached by a pin K through a
slot to the bar H, which carries the foot I and communicates thereto the
requisite motion for moving or propelling the boot or shoc or material,
being sewn the required length for the stitch, which length can be
adjusted by the two check nuts M. The return motion of the plate K,
and thereby of the bar H with the foot I, is effected with a spring L.
The presser foot I can be adjusted for different thicknesses of material
by means of the screw i; pressure is given by the spring shewn in
Fig. 2.
To the other face of the disc B is a stud with roller working in the
slotted cam to give motion to the needle bar G, which gives a better rest
to the needle. There is a slot in the disc B, and the stud that works in
the slotted cam E is adjustable for sewing different thicknesses of
material by varying the distance from the centre of the disc B, and
fixed with a nut N. The cam E, which has a projecting piece, is
attached to the needle bar G with a screw e, by the rotation of the
dise B and the communication through the cam E and pin and roller L,
after the manner of a crank motion, to the piece E, is caused to vibrate
in the bearings 3, 3, formed in the headstock of the machine, thereby
giving the requisite throw to the needle for effecting the formation of
the stitch. J is a lever for lifting the bar H, and with it the presser
foot I, so as to permit the boot or material to be sewn to be placed
underneath it. j is a lever working in connection with the needle bar G;

page_text: g is a roller and pin attached to the top end of the needle bar G;
is a projecting piece or rest, in form of a V or a segment of a circle,
which is fixed under the lever J.
When the lever bar G is down, as shewn in Figure 1, the pin g
comes in contact with the lever j, which causes the bar H and the foot I
to lift, and at that time the foot I is moved back to its starting point by the
plate K, the return motion of which is effected by the clastic force of the
spring L.
F is a cast-off for protecting the last preceding loop of
the sewing thread from being caught in the hook. The lower end F is
made taper, with a hole or slot in it for the needle and hook to pass
through, and, for the purpose just before mentioned is made to vibrate
up and down by means of the projecting piece c and the-adjustable
washer f, which is attached to the cast-off for the purpose of giving a
rest, as may be required. When the needle bar G ascends, and the pro-.
jecting piece E comes in contact with the washer F below the projecting
picce E by which the cast-off is forced down a spring is placed resting
upon the pin of the cast-off in order to enable it to yield, so as to
accommodate different thicknesses of material when being sewn. Qis a
screw, with leather or other suitable material in the screw hole, in order
when tightening the screw to cause friction in the cast-off F to cause the
cast-off to rest, to enable the loop of thread to be released from the hook.
The different bearings are shown by numbers thus, the bearings for
presser slide bar H, No. 1; the bearings of cast-off, No. 2; the bearings
for needle bar G, No. 3; and bearings for main shaft A, 5, 5; the
bearings for looper spindle R, 7, 7, 7.
The arm or horn O is provided with a hollow steel nose at the top end,
fixed by screws and tempered sufficiently to resist the needle cutting.
The looper spindle R, Figs. 3 and 4, is worked by an eccentric and rod
from the main shaft A to a cup and ball movement and a cam and pin,
see Figs. 3 and 4. The cam is shaped so as to give sufficient move-
ment to the looper spindle R, to give required movement round the
needle for passing the thread in the barb of the needle. The looper
spindle R and cam attached to it is shewn in No. 3 and 4; wax pot and
arrangement for same is shown at S, and mode of heating beneath.
In Figure 1 a shews a small groove pulley, which answers the purpose
of giving tension to the thread, and is run in centre b, with an adjustable
screw and check nut. The thread is checked by a spring, and the thread

near the bottom of the same by a pin, shewn at d, and passed betwixt
two plates or india-rubber p, p, for the purpose of regulating the wax on

the extreme end of the looper spindle R.
looper spindle to permit the point of the hook, and further should the
hook come in contact with a nail in the boot for giving clearance to pass
through.
There is a second hole in the
In lieu of the above named pulley a for giving tension to the thread,
I may adopt two washers, with spindle, spring, and adjustable nut, and
passing thread between the washers, which will give required tension to
the thread.
Having thus described the nature of my said Invention, and in what
manner the same is or may be performed, I wish it to be understood
that I do not claim any part separately, but what I consider as my im- 1
provement is, a better system of waxing the thread in combination with
the arrangement for heating the wax and also the machine within a
hollow pedestal and hollow framework of machine, so as to confine
and thus utilising the heat; and further, I claim the arrangement of
looper spindle with a hole to permit the barb of the needle to enter, and 2
the arrangement in combination for working the same, and also the
general construction of the machine.
In witness whereof, I, the said William Jackson, have hereunto
- set my hand and seal, this Eleventh day of December, in
the year of our Lord One thousand eight hundred and seventy- 2
four.
