Improvements in Sewing Machines.
I MONTAGUE WICZELL of 44 Hova Villas West Brighton in the County of
Sussex Artist do hereby declare the nature of this invention to be as follows:-
This my invention has for its object improvements in the mode of giving motive
power to sewing machines so as to make them self acting and to make it unnecessary to
use the foot treddle or constant hand power for working the machine whilst using
them thus giving the free use of both hands for arranging the materials or fabric
whilst it is being sewn, stitched or otherwise acted upon by the needle or thread.
According to my invention I apply a spring or springs either spiral or other
suitable kind in connection with the driving gear of the machine so that when the
said spring or springs have been wound up it or they will give rotating or revolving
motion to the driving gear of the machine and by the application of a brake acting
against the fly wheel or any other suitable part of the driving gear, the machine
can be put in motion or stopped at pleasure so as to keep the working of the
machine entirely under controle without the necessity of using the hand to keep
the machine working or the injurious action of the foot as at present required in
working the treddle machine. I also make the said machines self working by the
use of revolving governors or horizontal bars or arms with weights at their ends,
or by one or more pendulums acting on the driving gear-motion being given to the
same by a spring or springs or by hand at the starting of the machine when work
is to be done, or the required self action or motion may be given by a weight at
the end of a rope, cord, wire or chain working over a drum, roller, or wheel.

Improvements in Sewing Machines.
I MONTAGUE WIGZELL of 44 Hova Villas West Brighton in the County of
Sussex Artist 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 my invention has for its object improvements in the mode of giving motive
power to sewing machines so as to make them self acting and to make it unnecessary
to use the foot treadle or constant hand power for working the machines whilst
using them thus giving the free use of both hands for arranging the material or
fabric whilst it is being sewn stitched or otherwise acted upon by the needle or
thread.
According to.my invention 1 apply a spring or springs either spiral or other
suitable kind in connection with the driving gear of the machine so that when the
said spring or springs have been wound up it or they will give rotating or revolving
motion to the driving gear of the machine and by the application of a brake acting
against the fly wheel or any other suitable part of the driving gear the machine
can be put in motion or stopped at pleasure so as to keep the working of the
machine entirely under controle without the necessity of useing the hand to keep
the machine working or the injurious action of the foot as at present required in
working the treadle machine I also make the said machines self working by the
use of revolving governors or horizontal bars or arms with weights at their ends
Peine d

page_text: or by one or more pendulums acting on the driving gear, motion being given to the
same by a spring or springs or by hand at the starting of the machine when work
is to be done, or the required self action or motion may be given by a weight at the
end of a rope, strap, cord wire or chain working over a drum, roller, or wheel.
In carrying out this my invention if one or more spiral or other shaped springs
are used to give the revolving or motive power for working the sewing machine they
may be connected direct with the driving shaft or fly wheel by means of a tooth
wheel or wheels-such as ordinary spur or bevel or friction wheels or by elastic or
other bands or straps working over drums so as to transmit the action of the springs
to the said driving gear-and when the spring or springs are wound up I stop or
regulate the speed of working by means of a lever strap, screw or other suitable
brake or stopping apparatus-and when I produce the driving power by means of
the revolving governors or rods weighted at their ends I transmit the revolving or
rotating motion to the machine by means of bevel, tooth or friction wheels with or
without bands or straps working over drums, and I stop or regulate the speed by
a suitable brake as described above-and if the motion or driving power is given
to the machine by means of a weight at the end of a rope, strap, cord, wire or chain
working over a drum, roller or wheel I transmit the motion to the machine by
means of spur or other tooth wheels, straps, bands or friction wheels and I apply a
brake as before mentioned for stopping or regulating the speed.
Figure 1 represents the end view of the driving gear worked by a spiral spring B
enclosed in a case-A. is the fly wheel of sewing machine, D is the strap or elastic
band for working drum C-E is the strap or elastic band connecting drum C with
fly wheel A-F is the ratchet wheel acted upon by ketch G-spring N keeps
ketch G in ratchet wheel as the spring is wound up by spindle O by means of an
ordinary clock key-M forms the bed and bearings for spring B-I is the brake
raised or lowered by cambe K acting upon lever J-L is the bearing for lever J.
Figure 2 is the front view of driving gear and side view of fly wheel A of sewing
machine B is the spring case, O being the spindle for winding up the spring-E is
the connecting band for driving fly wheel A-D is the band for driving drum C-
J is the lever for lowering and raising brake I.
Figure 3 is the back view of fly wheel A and the driving apparatus-B is the
box with spring in it-0 the winding spindle-F the ratchet wheel, D the band
on drum P for driving drum C-band E is for driving fly wheel A-the brake I
acts upon drum Q which is part of drum P-J is the lever for starting and stopping
driving apparatus.
Figure 4, A is the drum with coil of strap wound up with weight B at its end which
passes down through the bed of apparatus-C is the upright frame work for
supporting drum A-D is a drum or wheel with band E for driving drum which
has band G for connecting with the drum on fly wheel of sewing machine H is the
brake which is made to work against drum I by pulling rod N.
Figure 5 is a side elevation of apparatus shown in igure 4-A is the drum with
coil of strap B the weight-C the supporting frame work-H the brake-K the
ratchet wheel to enable the weight B to be wound up by turning spindle L with an
ordinary clock key.
Figure 6 is a front elevation of driving apparatus with band A working over the
back of fly wheel B of sewing machine C is a spindle made to revolve by turning
the rod with weights D & E, the said spindle has a conical end or foot which passes
through the mitre or bevelled wheel F with its end working in hole or centre in
spindle G so that by raising up spindle G spindle C will be disconnected from the
mitre or bevelled wheel and the wooden brake H will stop the mitre wheel from
revolving.
Figure 7 shows a side view of Figure 6-J being the cambe moved by lever K
for raising or lowering spindle G.
The ratchet wheel F in the drawing Figure 1 is fixed to spindle O by key or in 5
any way so that it turns with spindle and ketch G is kept in its place by a screw
fixed into drum Q shown in Figure III.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
The application of springs revolving or moveable arms or rods with weights at
their ends either horizontal or vertical such as governors and pendulums or rope,
straps, cord, wire or chains working over drums rollers or wheels with a weight
attached which can be wound up for the purpose of giving motive power to sewing
machines such as are now made & used or hereafter to be made or used.
