I EDWARD WARD of 9 Wells Street, Oxford Street in the County of Middlesex,
Engineer, do hereby declare the nature of said invention to be as follows:-
My invention consists of a combination of parts, to enable the machine to be
worked by hand or foot without the usual extra appliances and also to economise
space.
The object of my invention is to construct a sewing machine to be worked by
causing the downward pressure of the finger to revolve a shaft in one direction only
by means of a band cord or chain passing round a drum or pulley which runs back-
wards and forwards on the driving shaft.
I do not confine myself to the band, cord or chain before described, but sometimes
employ a straight or curved rack the teeth of which engage with a ratchet wheel on the
driving shaft, or the motion can be produced by means of an endless band and a
gripping device acting thereon in one direction only.
The backward motion of the druin or pulley is caused by a coiled spring suitably
arranged in connection with the drum or pulley.
A friction or ratchet wheel is fastened on the driving shaft and a pawl or click
attached to the drum or pulley engages the friction or ratchet wheel and causes the
driving shaft to revolve in the desired direction to set the working parts in motion.
A friction pawl or roller or other suitable means is employed to prevent back action
of the driving or pulley shaft.
It will be seen that by this arrangement the difficulty caused in other classes of
portable sewing machines by breaking thread or deranging the machine through
failing to complete the stitch is obviated as no part of the machine will move in a
reverse direction, the drum or pulley and the actuating cord or other motive part
alone excepted.
This arrangement does not prevent the machine being worked on a stand by foot
power when required.
The arrangement is applicable to either a lock-stitch or chain-stitch sewing
machine.

page_text: When applied to a shuttle lock stitch sewing machine the axis of the drum or
driving pulley is intermediate of the needle and the axis of the needle arm and a stud
on a disc fixed on the driving shaft is connected by a link to the shuttle carrier which
works on a guide or guides longitudinally of the machine and at right angles to the
driving shaft.
When applying my invention to a spool lock stitch and to a chain stitch sewing
machine I place the axis of the drum or driving pulley underneath the needle and the
drum or its axis is fitted with the spool carrier and rotating hook.
The needle arm is formed double the upper part forming the ordinary needle arm
and the lower part the arm by which it receives motion such lower part being
formed with a suitably shaped groove within which works a stud carried by a disc on
the driving shaft.
The needle may be either curved or straight in the former case it is fixed directly to
the needle arm, in the latter it is carried by a slide working in the head of the
machine and connected to the needle arm in any suitable manner.
In order also to economise space I form the head of the machine with an open-
fronted guide to enable the needle holding screw and needle to slide up into the same.
The feed lever works on an axis at the back part of the machine and is operated by
suitable inclines.
The presser foot and tension apparatus may be of any convenient construction.
If desired multiplying gear may be interposed between the drum or pulley and the
driving shaft..

page_text: I, EDWARD WARD of 9 Wells Street Oxford Street, in the County of Middlesex
Engineer, 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 :-
My invention consists of a combination of parts to enable the machine to be
worked by hand or foot without the usual extra appliances and also to economise
space.
The object of my invention is to construct a sewing machine to be worked by
causing the downward pressure of the finger to revolve a shaft in one direction only
by means of a band, cord or chain passing round a drum or pulley which runs back-
wards and forwards on the driving shaft.
I do not confine myself to the band, cord or chain before described but sometimes
employ a straight or curved rack the teeth of which engage with a ratchet wheel on
the driving shaft or the motion can be produced by means of an endless band and a
gripping device acting thereon in one direction only.
The backward motion of the drum or pulley is caused by a coil spring suitably
arranged in connection with the drum or pulley.
A friction or ratchet wheel is fastened on the driving shaft and a pawl or click
attached to the drum or pulley engages the friction or ratchet wheel and causes the
driving shaft to revolve in the desired direction to set the working parts in motion.
A friction pawl or roller or other suitable means may be employed to prevent back
action of the driving shaft.
It will be seen that by this arrangement the difficulty caused in other classes
of portable sewing machines by breaking thread or deranging the machine through

When applied to a shuttle lock stitch sewing machine the axis of the drum or
driving pulley is intermediate of the needle and the axis of the needle arm and a stud
on a disc fixed on the driving shaft is connected by a link to the shuttle carrier
which works on a guide or guides longitudinally of the machine and at right angles
to the driving shaft.
When applying my invention to a spool lock stitch and to a chain-stitch sewing
machine I place the axis of the drum or driving pulley underneath the needle and
said axis is fitted with the spool carrier and rotating book.

Sme view ΟΙ a portable sewing machine constructed
Figure 2 is a back view; Figure 3 is a top or plan view; Figure 4 is an underside
view and Figure 5 is an end view of the same; Figure 6 is an underside view of the
feed lever and part of the work plate and Figure 7 is an elevation and Figure 8 is a
sectional plan of the head of the machine. All the above views are drawn to a size
that we have found suitable for the size of a practical machine.
Figure 9 is a cross section drawn on line 1. 1. of Figures 1 and 2 showing the
driving gear and some of the other parts of the machine. Figure 10 is an end view
of the driving gear and Figures 11, 12, 13 and 14 are detail views of the same and
Figures 15, 16 and 17 are respectively an elevation, a plan and a cross section
showing the shuttle, shuttle carrier and adjacent parts...
Figures 9 to 17 inclusive are drawn to a scale of double the real size.
In all the figures like parts are indicated by similar letters of reference.
a is a drum or pulley around which is passed a band b or it may be a cord or chain.
The band may be fixed in any suitable manner to the drum or pulley a but that
shown in the drawings has been found to answer well, this consists in passing a wire a¹
through holes formed in the flanges or cheeks of the drum or pulley a and in passing
the end of the band around such wire and then sewing it so as to fix it thereon after
which the band is passed completely round the drum or pulley a and then sewn to the
part first connected with the wire a'. The drum or pulley a runs backward and
forward on the driving shaft c, the backward motion of the drum or pulley a is
caused by a coiled spring d the outer end of which is fixed to the inner periphery of
the drum or pulley a whilst the other or inner end is fixed to the boss of a disc e
which is held stationary by a projection e' thereon entering a suitable hole or recess
forined in the framing, other suitable means may however be employed to obtain the
backward motion of the drum or pulley a. The boss a² of the drum or pulley a fits
with capability of running freely on the driving shaft c and one side of such boss a³
works freely within the boss e² of the disc e. A friction or ratchet wheel c¹ is fastened
on the driving shaft c and a pawl or click a³ attached to the drum or pulley a engages
the friction or ratchet wheel c' and on a downward pull being given to the band b
causes the driving shaft c to revolve in the desired direction to set the working parts
of the machine in motion. A friction pawl or other suitable means may be employed
to prevent back action of the driving shaft c but I have found that with the con-
struction of parts shown in the drawing such is not required.

page_text: It will be seen that by the above described arrangement of driving parts the
difficulty caused in some other classes of portable sewing machines by breaking thread
or deranging the machine through failing to complete the stitch is obviated as no part
of the machine will move in a reverse direction, the drum or pulley a the spring d
and the actuating cord, band or other motive part balone excepted
I do not confine myself to the use of a band, cord or chain for giving motion in
the one direction to the drum or pulley a but may employ a straight or curved rack
the teeth of which engage with teeth formed on the drum or pulley a or on a wheel to
which the ratchet wheel e¹ is fixed; or the required motion can be produced by means
of an endless band and a gripping device acting thereon in one direction only.
The above described arrangement of parts does not prevent the machine from being
worked on a stand by foot power when required as for such purpose it is only
necessary to connect the band b or other motive part to a treadle.
The above described arrangement of driving parts is applicable to either a lock
stitch or chain stitch sewing machine.
When applied to a shuttle lock stitch sewing machine as represented in the drawings
the axis c of the drum or driving pulley a is intermediate of the needle g and the
axis g² of the needle arm gl and a stud on a disc fixed on the driving shaft c is
connected by a link to the shuttle carrier i which works on a guide or guides j
longitudinally of the machine and at right angles with the driving shaft. That
portion of the shuttle carrier i which encloses the shuttle is mounted on an axis i so
as to enable the same when required to be raised into the position shown in Figure 15
to enable the shuttle to be readily removed from and replaced in the said shuttle carrier
a spring acting upon the tail of the shuttle carrier being employed to retain
the same either in its raised and open position or in its working or closed position.
The needle arm g¹ is formed double the upper part forming the ordinary needle
arm and the lower part the arm by which it receives motion such lower part being
formed with a suitably shaped groove 93 see Figure 1 within which works a stud k
carried by a disc & fixed on the driving shaft c.
The needle g may be either curved or straight in the former case it is fixed directly
to the needle arm g' in the latter as shown in the drawings it is carried by a slide g
working in the head of the machine which slide is connected to the needle arm g¹
by a screw stud y working in a hole in the end of the needle arm g¹ or in any
other suitable manner.
In order also to economise space I form the head of the machine with an open
fronted guide to enable the needle holding screw and needle to slide up into the
same the needle slide and its guide being of circular form.
The feed lever m works on an axis m¹ at the back part of the machine and it is
operated in the following manner; on the feed lever m are formed two arms or
projections m², m³ the arm or projection m² is curved or inclined on its underside
and is acted upon at the required time by the forward end of the link ² to raise
the feed lever whilst the downwardly projecting portion of the arm or projection m³
is inclined on its inner face and is acted upon at the required time to move the
feed lever sideways by the side of the link h³. A spring m³ is employed to produce
the return motion of the feed lever m. The traverse of the feed lever m and
consequently the length of stitch produced are regulated by the screw m³ acting
against the side of the feed lever m. The presser foot n is mounted in bearings in
the head of the machine, and is kept down to its work by a spring n' in the
ordinary manner.
The upper thread is led from the reel o partly around the pin p and is there
subjected to the pressure of a tension spring q, it is then carried downwards
and is passed through the fixed guide at the lower part of the head of the
machine it is thence carried upwards and is passed through the guide of the thread
handlers whence it is carried downwards and is passed through the fixed guide t
adjacent to the guide from which it is passed through the needle eye.
The thread handler is mounted on an axis s³, fixed to the arm of the machine and
is operated by the screw stud 9*.

page_text: u is the cover which is centred at u¹ to the frame of the machine and is used to
enclose the working parts of the machine.
For the purpose of enabling the machine to be fixed to a table I employ a cramp v
the upper limb of which passes through a hole in the back of the machine and
presses upon that part of the frame which extends across the bottom of said hole
whilst the lower limb of the cramp v is provided with a screw jaw which is screwed
forcibly against the underside of the table.
The driving band bis passed through a hole formed in the cover u and is provided
with a handle by which it can be operated and in order to prevent the possibility of
the band being pulled too far downwards a check string 62 is attached at one end to
the band band at the other to the cover u.
When applying my invention to a spool lock stitch and to a chain stitch sewing
machine I place the axis c of the drum or driving pulley a underneath the needle
and the said axis is fitted with the spool carrier and rotating hook.
I have not thought it necessary to illustrate the method of applying my invention
to a spool lock stitch and to a chain stitch machine as from the description above
given such will be readily understood by a competent mechanic.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. In sewing machines the peculiar combination and arrangement of parts sub-
stantially as herein shown and described and for the purpose stated.
2. In combination with the driving shaft of a sewing machine a friction or ratchet
wheel c', loosely mounted drum or pulley a, coiled spring d or its equivalent, stationary
