page_text: LETTERS PATENT to William Jackson, of 4, Spring Terrace, York Road,
Lambeth, London, in the County of Surrey, Mechanic, for the Invention
of "IMPROVED ARRANGEMENT OF THE PARTS IN SEWING MACHINES FOR USING
WAX THREAD FOR SEWING ON THE SOLES OF BOOTS AND SHORS"
PROVISIONAL SPECIFICATION left by the said William Jackson at the
Office of the Commissioners of Patents, with his Petition, on the 9th
December 1865.
I, WILLIAM JACKSON, of 4, Spring Terrace, York Road, Lambeth, London;
in the County of Surrey, Mechanic, do hereby declare the nature of the said
Invention for "IMPROVED ARRANGEMENT OF THE PARTS IN SEWING MACHINES
FOR USING WAX THREAD FOR SEWING ON THE SOLES OF BOOTS AND SHOES," to be as
follows:-
This Invention consists in the construction of a machine in a more simple
and effective manner than has hitherto been done for the purpose above
mentioned.
The accompanying Drawing shows the parts générally composing this
machine.
A represents the main shaft ; B is an excentric for the purpose of working.
the cam M in communication with the rod P, and the pin N in connection
with an arm; L is for the purpose of showing in what manner the thread is
passed through-the end of the rod P for the purpose of putting the thread in

page_text: the barb of the needle; this arrangement being more simple and effective
than hitherto; shows the spool for the thread:; C is a bent lever for the
purpose of pressing and relieving the foot H in connection with the bent rod
G; D is a spring for causing pressure on the lever C, which is in communi-
cation with the rod G and the foot H, for giving necessary pressure on the
work when sewing; E is a disc for the purpose of working the connecting rod
F in communication with needle bar J, and connected with the looper bar K;
the bar K is bent having a hole at the lower end to permit the booked needle
to pass through it and for the purpose of protecting the last preceding loop
from being caught in the hook when sewing; I is a pin and roller working
in connection with the disc E for giving the required length of stitch.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Jackson in the Great Seal Patent Office on the
9th June 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JACKSON, of 4, Spring Terrace, York Road, Lambeth, London, in the County
of Surrey, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of December, in the year of our. Lord One
thousand eight hundred and sixty-five, in the twenty-ninth 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 executors, 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 "IMPROVED ARRANGE-
MENT OF THE PARTS IN SEWING MACHINES FOR USING WAX THREAD FOR SEWING
ON 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 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.

page_text: 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 per-
formed, to be particularly described and ascertained in and by the following
statement:-
,
This Invention consists in the construction of a machine in a more simple
and effective manner than has hitherto been done for the purpose above
mentioned..
,
In order to explain my said Invention completely, I annex a Sheet of
Drawings, in which Fig. 1, is a side elevation; Fig. 2, is a front elevation ;
Fig. 8, a plan; Fig. 4, shews the shape of recess in the cam M.
In Fig. 1, A represents the main shaft running in suitable bearings, and
which may be driven by a treddle or any other convenient method; B is an
excentric for the purpose of giving the required motion to the cam M; S is a
cup-and-ball joint to attach the cam M and the rod P to work together back-
ward and forwards and partly with a circular motion, and for putting the thread
in the barb of the needle when the needle has descended to its lowest point.
The manner in which the thread is passed through the end of the rod P and
through the needle hole in the end of the arm is shewn at L; O is the spool,
and P¹ is a pin and roller working in the groove or recess of the cam M; E
is a disc secured to the end of the shaft A, the face of the disc having a pin
and groove in it, and thus being adjustable to different thicknesses of material,
the pin works in one end of the connecting rod F, the other end of the rod F
working with the projecting piece which is attached to the needle bar J. A
part of the face of the disc E is recessed for the purpose of propelling the foot
H, the bent rod G, and the pin and roller I, which are all attached to each
other for giving the required length of stitch; R is a spring for giving the
return motion to the foot H and the bent rod G; Q is a screw for regulating
the length of stitch; T is a lever or handle for raising the foot H, when
the work is to be put under to be sewn; E' is a pin and roller attached
to the back of disc E for the purpose of raising the bent lever C, and
relieving the pressure of the foot H. The spring D is for giving pressure to
the bent lever C and the foot H to effect the necessary pressure on the work
when sewing; V, V, as shewn in plan of Fig. 3, are centre screws with
check nuts for keeping the bent lever C in position; referring to Fig. 1, k is
the looper bar, having a spring on it to permit the bar to yield according to
the thickness of the material to be sewn; K³ is a screw having leather between
the looper bar and the screw end, the screw is for giving more or less friction
to the looper bar, it being necessary for the bar K to rest for a time to release
the thread from the hooked needle. The bar K is bent, having a hole at the

page_text: lower end to permit the hooked needle to pass through it, and for the purpose
of protecting the last preceding loop from being caught in the hook while
sewing; it is carried down by the projecting piece J' on the needle bar J, which
comes in contact with a loose washer K" on the bar K; the lower washer is
fastened by a pin or screw. The ascending motion is given by the top end of
the needle bar, which comes in contact with a projecting piece at the top end
of the lever K; Fig. 4 is a plan view of the cam M shewing the shape of the
groove or recess in the cam.
Having thus described the nature of my said Invention, and the manner in
which the same is to be performed, I would remark that I do not limit myself
to the exact details and configuration of parts I have expressed and shewn,
as the same may be slightly varied or modified without in any way departing
from the principles of the Invention.
I claim, firstly and specially, the arrangement for working a thread con-
ductor in combination with an arm. This arrangement dispenses with wheels
or a joint which has in all cases before been used for the aforesaid purpose.
The machine is thus rendered far more desirable, its construction is greatly
simplified and consequently cheapened.
I claim, secondly, the general combination, arrangement, construction, and
mode of operating the several parts substantially as herein specified and shewn
by the Drawings annexed.
In witness whereof, I, the said William Jackson, have hereunto set my
'hand and 'seal, this Fourth day of June, in the year of our Lord One
thousand eight hundred and sixty-six.
