the hand-working machine in place of wheel a when desired to work by the
foot.
.
a is the fly wheel fastened upon the arbor of the toothed wheel b, driving
the pinion c, which is fixed to a shaft running through the body of the machine
marked d, and terminating in the form of a disc or crank at e. To this disc
is attached the slide f working upon the fulcrum screw 9, the other end being
attached to the frame of the machine by the screw h. In this slide works the
needle bar attached to the disc or crank by the afore-mentioned screw g.
The needle z, which is a common eye pointed one of the (so called) "Singer"
pattern, but about one-third-shorter in shank, is set in the bar under the
table x, x, and held in place by the screw k; upon the top or end of the said
bar, in which the needle is fixed, is inserted a toothed or roughened surfaced
pin of about ths of an inch in length, or whatever is necessary for the
purpose of feeding the cloth or fabric; the spool, which supplies the needle
with thread, is attached to the needle bar just above the screw g; m is a
regulator having an oblique slot for the purpose of varying the length of
stitch; the screw h is attached to the sliding block n moving in the groove o;
p is the cloth holder, held down by the spring 9 or by a flat spiral spring
,placed in the slot of the cloth holder; r is the looper attached to the rod s
by a pin joint; t is a set or stop screw; u is a spring for the purpose of
pressing the point of said screw against the arm of the frame.
end of the rods is continued down to the cam v on the pinion c.

The lower
This cam
gives a lateral or vibrating motion to the looper r; which by being pressed
'at the same time against the lower and square end of the arm has a to-and-
fro motion at right angles to its motion before mentioned. This compound
motion is necessary to bring the loop into such a position that the needle
in making the next stitch shall pass through the loop. When only one
thread is required the double looper No. 5 is replaced by the single thread
looper shown in Figures 7, 8, & 9, the action of which is precisely the same.

removal of the pin on which they are suspended. The secondary details of
form, dimension, and general construction of the machine may be varied
according to circumstances.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Marc Antoine François Mennons in the Great Seal
Patent Office on the 3rd August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the Firm of Mennons and Telescheff,
Home and Foreign Patent Agents, of Abingdon Chambers, in the City
of Westminster, and 24, Rue de Dunkerque, Paris, in the Empire of France,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of February, in the year of our Lord
One thousand eight hundred and sixty-four, in. the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Marc Antoine François Mennons, Her special licence that I, the
said Marc Antoine François Mennons, my executors, administrators, and
assigns, or such others as I, the said Marc Antoine François Mennons,
my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE CONSTRUCTION
OF SEWING MACHINES," (a communication from Joseph Weatherby Bartlett, a
person resident at 442, Broadway, New York, in the United States of America,)
upon the condition (amongst others) that I, the said Marc Antoine
François Mennons, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should parti-
cularly describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Marc Antoine François Mennons,
do hereby declare the nature of the said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in
and by the following statement, that is to say :-
This Invention relates to improvements in the construction of sewing
machines, as shewn by the accompanying Drawing, in which Figure 1 is a
perspective view of the complete machine; Figure 2 is a full size elevation
of the disc or crank, needle bar, regulator, and spool and holder; Figure 3 is
a side elevation of the above; Figure 4 is a full size end elevation, showing
the wheels, cam, and rod, rear of the machine; Figures 5 & 6 are front and
side elevations of the double thread looper (in full size); Figures 7, 8, & 9
are front, side elevation, and plan of the single-thread looper, to be substituted
for Nos. 5 & 6 when but one thread is required; Figure 10 is a general
view of the machine with treadle and table combined; Figure 11 represents
separate attachment of treadle wheel, rod, and sockets to be attached to the
band working machine in place of wheel a when desired to work by the
foot.
a is the fly wheel fastened upon the arbor of the toothed wheel b, driving
the pinion c, which is fixed to a shaft running through the body of the machine
marked d, and terminating in the form of a disc or crank at e; to this disc
is attached the slide f, working upon the fulcrum screw g, the other end
being attached to the frame of the machine by the screw h. In this slide
works the needle bar i, attached to the disc or crank by the afore-mentioned
screw g. The needle z, which is a common eye pointed one of the (so called)
"Singer" pattern, but about one-third shorter in shank, is set in the bar
under the table x, x, and held in place by the screw k. Upon the top.or
end of the said bar in which the needle is fixed is inserted a toothed or
roughened surfaced pin of about 1 (three-sixteenths) of an inch in length, or
whatever is necessary for the purpose of feeding the cloth or fabric. The
spool 7, which supplies the needle with thread, is attached to the needle bar
just above the screw 9; m is a regulator having an oblique slot for the purpose
of varying the length of stitch. The screw h is attached to the sliding block
n, moving in the groove o; p is the cloth holder, held down by the spring q
or by a flat spiral spring placed in the slot of the cloth holder; r is the looper
attached to the rod s by a pin joint; t is a set or stop screw; u, a spring, for
the purpose of pressing the point of said screw against the arm of the frame.
The lower end of the rod s is continued down to the came on the pinion c;
this cam gives a lateral or vibratory motion to the looper r, which by being
pressed at the same time against the lower and square end of the arm, has a
to-and-fro motion at right angles to its motion before mentioned. This
compound motion is neccssary to bring the loop into a such position that the

page_text: needle in making the next stitch shall pass through the loop. When only
one thread is required, the double looper No. 5 is replaced by the single
thread looper shown in Figures 7, 8, & 9, the action of which is precisely the
same. The substitution of these loopers for each other is accomplished by
the simple removal of the pin on which they are suspended. The secondary
details of form, dimension, and general construction of the machine may be
varied according to circumstances.
Having now described and ascertained the nature of the said Invention,
and the manner of carrying it into effect, I declare that I claim the appli-
cation to the construction of single or double thread sewing machines of the
improved combination of mechanism, substantially as herein set forth and
represented in the Figures of the annexed Drawing.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereto set my hand and seal, this Second day of August, in the year
of our Lord One thousand eight hundred and sixty-four.
