PROVISIONAL SPECIFICATION.
An Improved Sewing Machine.
I HARRY MANNING, of 39 St. Andrew's Hill, in the City of London,
Accountant, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved sewing machine, and consists in a special
combination of parts and in the forms of the various cams employed, by which a
very simple and portable lock-stitch sewing machine is produced.
And in order that my invention may be understood, I will refer to the drawings
accompanying this specification, in which Fig. 1 shews side elevation of a machine,
constructed according to my invention, Fig. 2 shews back elevation of the same,
shewing the whole of the mechanism, Figs. 3 to 7 inclusive shew detached parts
hereinafter referred to.
At each of the above figures the same letters of reference are employed to
denote the same parts.
According to this invention, I mourt in a framing a a spindle b, on which is
keyed a disc c, one side of the disc c is provided with a crank pin e, working in a
cam f, fixed on the needle bar g, so as to actuate the said, needle bar at the proper
time. On the disc c, or in connection therewith, I provide a tappet action h,
working in a cam y, so as to actuate the feed. presser-bar i, and on to the opposite
side of the disc c, I provide a cam k, working in a cam, to actuate the shuttle
driver. This cam is shewn detached at Fig. 5. The tappet action h is also
shewn detached at Fig. 7.
I groove the periphery of the disc c so that a small wheel.m may work in the
said groove when the machine is worked, such wheel being. connected to a spring
hook n pivotted to the frame a of the machine, by which means the wheel m may
be put into and out of action. A short spindle o passes through back of hook n.
to which spindle the wheel m is keyed, so that when the spool is sprung between
the end of the hook and the spindle o, cotton is wound on to the spool by
actuating the machine. On to the disc c I fix concentrically a pinion p, into
which a toothed wheel g mounted in bearings r in the frame a engages, by which
means the machine may he worked, either by hand or treadle, by the grooved
wheels. The handle t, by which the machine is worked, I prefer to have folding,
as shewn, for the sake of compactness, when the machine is not in use. On to the
top of the frame is fixed or formed a vertical pin. u.to.carry the reel of cotton.
I further propose to fix or form on the framing a a clamp y so that it will be
unnecessary to have a stand, as the machine can be clamped on to a table, bracket
or shelf w.
Figs. 3 to 6 inclusive shew the exact forms of cams detached,. as these special
forms are necessary to insure the proper working of the. machine.
Although I have described and shewn the machine clamped on to a table or
shelf it may of course be fitted on to a stand.
I propose to enclose the whole of the mechanism in a suitable casing.
Dated this Eighteenth day of March 1896.

1 HARRY MANNING, of 39 Saint Andrew's Hill, in the City of Loudon,
Accountant, 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 an improved sewing machine, and consists in a special
combination of parts and in the forms of the various cams employed, by which .a
very simple and portable lock stitch sewing machine is produced.
And in order that my said invention may be fully understood I will now proceed
to describe the same with reference to the drawings accompanying the Provisional
Specification, in which Fig. 1 shews a side elevation of a machine, constructed
according to my invention, Fig. 2 shews back elevation of the same, representing
the whole of the mechanism, Figs. 3 to 7 inclusive shew detached parts hereafter
referred to.
At each of the above figures the same letters are employed to denote the same
parts.
According to this invention I mount in a framing.a a spindle b on which is keyed,
a disc c one side of the disc c is provided with a crank pin e working in a cam f
fixed on the needle bar g, so as to actuate the said needle bar at the proper time.
On the disc c or in connection therewith I provide a tappet action h working in a
cam y which latter oscillates about the pin and thereby actuates the feed presser
bar i, and on the opposite side of the disc c I provide a cam k working in a cam,
to actuate the shuttle driver l. This cam is shewn detached at Fig. 5. The
tappet action h is also shewn detached at Fig. 7.
I groove the periphery of the disc c so that a small wheel m may work in the
said groove, when the machine is worked, the spindle of such wheel being
connected to a spring hook n, pivotted to the frame a of the machine, by which
means the wheel m may be put into and out of action. A short spindle o passes
through back of hook n, to which spindle the wheel m is keyed, so that when the
spool is sprung between the end of the hook n and the spindle o, cotton is wound
on the spool by actuating the machine. On to the disc c 1 fix, concentrically a
pinion p, into which a toothed wheel 9 mounted in bearings r in the frame a engages,
by which means the machine may be worked, either by hand or treadle, by the
grooved wheels. The handle t, by which the machine is worked, I prefer to have
folding, as shewn, for the sake of compactness, when the machine is not in use.
On to the top of the frame is fixed or formed a vertical pin u, to carry the reel of
cotton, which cotton is controlled by the spring a', in the usual way.
I further propose to fix or form on the framing a, a clamp v, so that it will be
unnecessary to have a stand, as the machine can be clamped on to a table, bracket
or shelf w.
Figs. 3 to 6 inclusive shew the exact forms of cains, detached, as these special
forms are necessary to ensure the proper working of the machine.
Although I have described and shewn the machine clamped on to a table or
shelf, it may of course be fitted on to a stand.
.
I propose to enclose the whole of the mechanism in a suitable casing.
I have found in practice that by using the exact form of cam shewn at k, I
can do away with noise and vibration, aud make the machine work quietly and
easily.

page_text: 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 employment of a cam k, of the particular form shewn
at Figs. 3 and 5, in the drawings accompanying the Provisional Specification.
2. In the improved sewing machine, the general arrangement of parts, in
combination with the particular form of cam k, shewn at Figs. 3 and 5 on the
drawings accompanying the Provisional Specification, all substantially as set forth..
