Improvements in or relating to Two-Reel Sewing Machines.
I, WILLIAM PHILIP FRICKER, of 4 Great Portland Street, Oxford Circus, County
of London, Sewing Machine Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention has for object certain improvements in or relating to Two reel
Sewing Machines.
For the purpose of my invention, I fit on the under shaft a disc or its equivalent
carrying a hook or looper of such shape and form that as it travels round a reel
holder it draws the loop from the needle which loop is opened out by the angular
shape of the cage in which the holder and reel are placed.
I arrange segmental plates on the face of a plate fitted in front of the front foot
of the Machine and these by cam motion are successively moved outwardly to allow
the hook or looper to pass, they being otherwise in its path to retain the Cage in
position.
One of said segmental plates is carried on the axle of a draw hook which receives
outer thread of the loop and virtually acts as a take up under the work plate. This
draw hook axle has at its inner end a shaped plate operable by an edge cam for one
travel and is returnable by a spring which also keeps the shaped plate in contact.
The release of the loop thread from the draw hook is effected by the next travel or
action of the needle, said loop thread then being slack. The pull of the hook
or looper is sufficient to draw a further quantity of thread from the upper reel or
bobbin for each stitch.
The lower reel carrier is composed of a central tube to go over a pin of a disc and
is affixed to a back plate from which a hood or screen projects forwardly, said hood
having the perforated or other tension piece for the lacing of the lower thread.

Improvements in or relating to Two-Reel Sewing Machines.
1, WILLIAM PHILIP FRICKER, of 4 Great Portland Street, Oxford Circus, County
of London, Sewing Machine Manufacturer, 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 has for object, certain improvements in or relating to Two reel
Sewing Machines.

page_text: For the purpose of my invention, I fit on the under shaft a disc or its equivalent
carrying a hook or looper of such shape and form that as it travels round a reel
holder it draws the loop from the needle, which loop is opened out by the angular
shape of the cage in which the holder and reel are placed.
I arrange segmental plates on the face of a plate fitted in front of the front foot
of the Machine and these by cam motion are successively moved outwardly to allow
the hook or looper to pass, they being otherwise in its path to retain the cage in
position.
One of said segmental plates is carried on the axle of a draw hook which receives
the outer thread of the loop and virtually acts as a "take up" under the work
plate. This draw hook axle has at its inner end a pinion operable by a quadrant rack.
The pull of the hook or looper is sufficient to draw a further quantity of thread
from the upper reel or bobbin for each stitch.
The lower reel carrier is composed of a central tube to go over a pin of a disc
and is affixed to a back plate from which a hood or screen projects forwardly,
said hood having the perforated or other tension piece for the lacing of the lower
thread.
My invention will be well understood by reference to the annexed drawings.
Figure 1 front elevation with the lower reel holder and cage removed.
Figure 2 similar elevation with lower reel holder and cage in position.
Figures 3 and 4 detached plan and front elevation of cage.
Figure 5 front elevation of lower reel holder.
Figure 6 plan of same with lower reel in position and showing the tension
appliances.
Figure 7 side elevation of lower reel holder without the reel.
Figure 8 back elevation of the additional plate which I secure to the frame
in front of the front foot of the Machine.
A, is the base of a Sewing Machine. B, the work plate. C, the head. D, the
presser foot. E, the needle, all these are of the usual construction and need no
further description. F, is an additional plate fixed to the base A and which carries
all the parts forming my invention which consists of a revolvable disc G having a
cam race G¹ in front, within which bowls H, H, H, H, have motion from the
pivots I, I, I, I, for operating studs J, J, J, J, working from the same pivota to enter
and retire from holes K, K, K, K, formed in the periphery of the cage L as the
looper M on the revolvable disc G travels round upon and with the lower shaft I'
of the Machine. The cage L has a central pin Q on which the central tube R of
the lower reel holder is placed and within which it is enclosed so that the loop of
the upper thread opens out around the cage L and is clear of the face R₁ of the
lower reel holder which is flush therewith. The lower reel holder is provided with
a hood S supporting the tension appliance T, this being formed from a bent strip
of springy metal U and a curled wire, the former of which is adjustable for tension
purposes by a screw pin V. W, is the "take up" mounted on a pin X passing to
the back of the additional plate F and on which is mounted a pinion Y operable by
a quadrant rack, Z, this being pivoted at a and controlled by a bowl b riding in a
cam race c formed in the back of the same cam-disc G, on the opposite or front face
of which the cam race G1 exists.
d is a guard, against which the loop of the upper thread bears while the "take up
is pulling the stitch tight.
The process is as follows: A reel of thread is placed upon reel holder and
threaded or passed through the tension appliance attached thereto. The real holder
is now placed inside cage, the hollow rod sliding on to the projecting rod of said
cage by a slight turn to the right whereby the reel holder is locked within it.
When the needle has formed the loop, the looper seizes the thread and carries it
forward, the studs leave the holes in the cage in succession and then closing again
for the loop to pass round the cage until caught by the "take up" which takes
the thread off the looper and bears against the guard while pulling up the slack thread
and completing stitch.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. In a Two reel Sewing Machine, the combination of appliances arranged in
the manner described and carried by an additional plate but operable by or from
the lower shaft thereof, as set forth and substantially as shown on the annexed
drawings.
2. In a Sewing Machine, affixing a plate such as F in front of front foot carrying
a revolvable disc G with cam races G¹ fixed on under shaft P for operating
studs J, J, which support and are removed in succession from a cage L, the race c
operating by its quadrant rack the "take up," all as described for the purposes
set forth.
