Improvements in Sewing Machines.
We JOSEPH FLETCHER of Load of Mischief Inn, Clayton-le-Moors, Accrington
in the County of Lancaster, Licensed Victualler, and CHARLES BROWN of 27 Peel
Hall Street, Preston in the county aforesaid, Mechanic, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in what are known as two reel sewing
machines i.e. sewing machines in which two ordinary bobbins or reels of thread are
employed, and consists of improvements in appliances for operating the needle bar ;
improvements in appliances for operating the feed motion, and regulating and
adjusting the length of stitch, and an improved thread carrier for carrying the
thread over the reel case and loop former. The machine constructed according to
this invention being of simple construction less expensive to manufacture, and
capable of running at a high speed the use of all cams being dispensed with.
According to this invention the needle bar is operated by means of a crank one
end of which is connected to the needle bar and the other end to a disc on the
main driving shaft.
The feed bar is connected to a slotted arm the lower end of which is carried on
an eccentric on the bottom shaft of the machine. In the slot of the arm is a
moveable block or stud carried in the end of a lever free to move on a fulcrum stud,
the other end of the lever being by connecting link attached to a thumb lever by
which the lever can be moved on its fulcrum stud.
The moveable block or stud forms the fulcrum of the feed bar and the eccentric
gives the requisite up and down and to and fro motion to the feed top, and it will
be seen that by moving the thumb lever the position of the moveable block or stud
can be changed and the length of stitch adjusted.
The thread carrier consists of a double barbed hook carried on a lever the lower
end of which is free to slide in a slot which allows of an up and down motion
of the thread carrier, and the requisite to and fro or sweeping motion of the
thread carrier is given by means of a disc or lever operated by the same eccentric
that works the feed bar.
By the eccentric and slot a sweeping partly circular motion is imparted to the
thread carrier so that the latter lays hold of the thread close to the eye of the
needle and carries it over the reel case and loop former and leaves it at the back
of the reel case until taking the next stitch, when the thread so leit is again used,
there being no take up motion, pad or brush employed.
Dated this 21st day of August 1894.

page_text: We JOSEPH FLETCHER, of Load of Mischief Inn, Clayton-le-Moors, in the
County of Lancaster, Licenced Victualer, and CHARLES BROWN, of 27 Peel
Hall Street, Preston, in the county aforesaid Mechanic, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in what are known as two reel sewing
machines i.e. sewing machines in which two ordinary bobbins or reels of thread
are employed, and the invention consists of improvements in the appliances for
operating the needle bar for operating the feed motion, and regulating and
adjusting the length of stitch, and for carrying the thread over the reel case and
loop former. The machine constructed according to this invention is of simple
construction, is inexpensive to manufacture, and is capable of running at a high
speed.
Such being the nature and object of our said invention; the following is a
complete description of same, reference being had to the accompanying drawings,
in which :-
Fig. 1 is a side elevation of an improved sewing machine made in accordance
with this invention, part of the frame being broken away in order to illustrate the
invention more clearly.
Fig. 2 is an end elevation of Fig. 1.
Fig. 3 is an end or front elevation of the reel carrier or case, and thread carrier,
on an enlarged scale.
Fig. 4 is a side elevation of Fig. 3.
Fig. 5 is an end view of the reel case frame.
Figs. 6, 7, and 8 are end and side views of the reel case.
Fig. 9 is an end elevation, and Fig. 10 a side elevation of the feed bar and
appliances connected therewith.
According to this invention, the needle bar 1 is operated by means of an arm 2;
one end of which is connected to the needle bar 1, and the other end to a disc 3, or
a crank on the end of the main driving shaft 4.
The feed bar 5 (Figs. 1, 9, and 10) is connected to a slotted arm 6, the lower
end of which is carried on an eccentric 7 on the bottom shaft 8 of the machine.
In the slot 9 of the arm 6 is a moveable block or stud 10 carried in the end of a
lever 11 pivoted at the point 12, the other end of the lever being by connecting
links 13, 13 (Fig. 1) attached to a thumb lever 14, by which the lever can be
moved on its fulcrum stud at the point 12.
The moveable block or stud 10 forms the fulcrum of the feed bar 5, which is
provided with the usual teeth 15, and the eccentric 7 gives the requisite up and
down, and to and fro motion to the same, a spring 6 attached to a stud on the
underside of the plate 29 assisting it and preventing "play," and it will be
seen that by moving the thumb lever 14, the position of the moveable block or
stud 10 can be changed in the slot 9, and the length of stitch so adjusted and
regulated.
The moveable block or stud 10 is carried on a stud 16, which stud 16 is received
in a hole in the boss 17 on the end of the lever 11, so that the block 10 is at liberty
to turn slightly with the arm 6. A pin 18 passed through the end of the stud 16
keeps the latter in place.
The thread carrier or looper (Figs. 1, 7, 3, and 4) consists of a barbed hook 20,
and a shoulder 21 carried by a lever 19, the lower end 22 of which is free to slide
in a slot 23 in a bracket 34, which allows of an up and down motion, as well as the
requisite to and fro or sweeping partly circular motion of the thread carrier or

page_text: looper, such motion being given by means of a disc crank or lever 24 carried by
the shaft 8 that works the feed bar 5. As shewn in the drawings, the outline given
to the disc or lever 24 is that of a cam, but this is only used when a cam edge is
required for operating a special attachment forming no part of the present
invention.
The reel case 26 (Figs. 6, 7, and 8) is carried in a frame 27 (Fig. 5) carried by
a slide piece 28 in the plate or bed 29 of the machine, so that the reel case is
readily removed for any purpose, such as for a new reel to be placed in position.
At 30 is a wheel driven by hand or power, and this in turn drives the main
shaft 4 and needle bar 1 as hereinhefore described. On the shaft 4 is a double
crank 31, 31, connected by links 32, 32 to corresponding double cranks 33, 33 on
the bottom shaft 8, which is carried in the brackets 34, 34 cast to the underside
of the bed plate 29.
The reel case 26 consists of a metal shell having a rib 26, in which is a hole 26b,
the shell itself having a long slot 26° therein, through which the thread is drawn, and
in which it may move to and fro as it is unwound from the reel. The thread is
subsequently taken through the hole 26°. The frame 27 for holding the reel case
is formed in segments or parts. One main portion consists of a curved side 27"
carrying a plate 27 at right angles thereto, such plate sliding in a groove formed
by the lugs 28 on the plate 28, and being secured to the latter by a screw 27°.
The part 27 is provided with a spring 27ª (Fig. 5) such spring serving to keep the
case 26 in position. A screw 27 holds the spring in place.
The other main portion of the frame 27 consists of the curved part 27' having a
plate 27 at right angles thereto, which is held to the plate 28 in a similar manner
to the plate 27º.
The
The two parts 27' and 27ª are connected at the back by a plate 27* secured by
screws. The frame is thus adjustable to take reel cases of various sizes, as by
moving the parts 27 and 27' in different directions (after having removed the back
plate 27) the case can be arranged for a larger reel if a wider back plate is put
Oui. The whole frame 27 may also be adjusted in position. The parts 27° and 27'
are moved by loosening the screw 27° (which may pass through a slot in the
plate 27) and the corresponding screw passing through the plate 278.
construction of the frame 27, however, may be varied from that above described.
The thread is drawn from the reel 50, and passes over a tension device 51, and
from thence in the usual way to the eye of the needle. When the needle takes
the thread through the opening in the bed plate, the hook 20 of the thread carrier
or looper, is brought into position above the frame 27, and takes hold of the thread
close to the needle, the thread slipping in a loop right over the hook 20, and being
caught by the shoulder 21. The circular motion of the looper being continued,
the loop is drawn over the pointed end of the case 26, and carried underneath to
the back of same, where the hook 20 leaves the loop and is ready to repeat the
operation. No more thread than the length of the stitch is drawn off the reel, as
the hook takes up the slack left by the preceeding loop, and thus no take up
motion is required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
(1.) The general construction, arrangement, and combination of parts constituting
the improved two reel sewing machine as herein described and substantially as
illustrated by the annexed drawings.
(2.) The feed bar 5, slotted arm 6 carried on an eccentric 7 on the shaft 8, the
moveable block or stud 10, and fulcrum lever 12, all in combination, as and for the
purpose herein described, and substantially as illustrated by Figs. 1, 9, and 10 of
the accompanying drawings.
(3.) In a two reel sewing machine, a thread carrier or looper consisting of a
barbed hook 20 having a shoulder 21 forming part of the lever 19, and carried in a

page_text: slot such as 23, disc or crank 24, and shaft 8, all in combination as and for the
purpose herein described and substantially as illustrated by Figs. 2, 3, and 4 of the
annexed drawings.
