page_text: I, ANGEL VALETTE, Blacksmith and Farrier, of Lapéruse, in the Canton of
Chabanais, Charente, in the Republic of France, do hereby declare the nature of
this invention to be as follows:-
The purpose of this improved motor is intended to be used in replacement of
the pedal in sewing machines.
This driving force is constituted by a series of four juxtaposed springs round a
horizontal cylindrical axle on which one end of each is fastened by means of screws.
The other extremity of each spring is equally fixed by two screws to the inner
wall of a cylinder of sheet iron which encloses them as in a box.
The winding of these four springs round the central axle is effected simul-
taneously by means of a system of gearing put into movement by a crank handle
provided with a movable pinion placed at the extremity of its rod.
This pinion turns a toothed wheel fixed on the central arbor. This wheel also
gears with another pinion fixed to a spur wheel which at the time of winding turns
loosely on an arbor of another wheel but during unwinding rotates the latter by
means of a ratchet wheel and pawl and so operates a gear train.
The movable pinion which serves for the winding up of the apparatus is, during
the operation of the said apparatus, displaced by a disengaging lever which slides
it on its rod to a neutral position.
The gear train ends with a chain wheel which operates by means of its teeth a
chain which again turns another wheel of half the size which is fixed on the
centre of the fly-wheel of the machine.
A wheel fixed on the box enclosing the gearing and provided with teeth only on
a part of its circumference serves for locking the spring barrel after a certain
time or otherwise.
A brake lever intended for regulating the motion of the machine and even to
stop it if necessary, is pivoted on a framing provided under the driving wheel.
By pressing on its roughened end, a sufficient pressure is transmitted to the driving
wheel by means of the other end of the lever to moderate or to stop the motion of
the machine. This latter end of the brake is faced with caoutchouc in order to
increase the friction.
This apparatus can be applied to any system of sewing machines.

I, ANGEL VALETTE, Blacksmith and Farrier, of Lapéruse, in the Canton of
Chabanais, Charente, in the Republic of France, 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 improved motor is intended to be used in replacement of the pedal in sew-
ing machines, and is shown in the annexed drawings in which Fig. 1 is an end
elevation and Fig. 2 a part front elevation partly broken away to show the con-
struction.
The driving force is constituted by a series of four juxtaposed springs A round
a horizontal cylindrical axle B on which one end of each is fastened by means of
screws a.
The other extremity of each spring is equally fixed by two screws to the inner
wall of a cylinder c of sheet iron which encloses them as in a box.
C
The winding of these four springs round the central axle B is effected simul-
taneously by means of a system of gearing put into movement by a crank handle D
provided with a movable pinion E placed at the extremity of its rod.
This pinion E turns a toothed wheel H fixed on the central axle B. This
wheel H also gears with another pinion I fixed to a spur wheel J.which at the
time of winding, turns loosely on an axle K of another wheel L but during un-
winding rotates the latter by means of a ratchet wheel and pawl and so operates
a gear train.
The movable pinion which serves for the winding up of the apparatus (see
position shown in the annexed drawing) is, during the operation of the said
apparatus displaced by disengaging lever F which slides it on its rod to a neutral
position indicated by dotted lines G Fig. 2.
The springs in unwinding move the wheel H fixed at the extremity of the
central axle B. This wheel which gears with the pinion I fixed at the centre
of the spur wheel J operates the wheel L by means of a movable pawl M fixed
on one of its extremities behind said wheel L and maintained in engagement by a
spring N fastened on the same wheel by means of two rivets c c.
The wheel L gearing with a pinion O fixed on an axle P which surpasses the
box of the apparatus turns the toothed wheel Q equally fixed on this axle.
This wheel operates by means of its teeth a chain which again turns another
wheel Qof half the size which is fixed on the centre of the fly wheel of the
machine.
A wheel R fixed on the box enclosing the gearing and provided with teeth only
on a part of its circumference serves for locking the spring barrel after a certain
number of revolutions so that the springs cannot be overwound.
A brake lever S intended for regulating the motion of the machine and even to
stop it if necessary is pivoted on a framing provided under the driving wheel T.
By pressing on its roughened end a sufficient pressure is transmitted to the driv-
ing wheel T by means of the other end of the lever to moderate or to stop the
motion of the machine. This latter end of the brake is faced with caoutchouc in
order to increase the friction.
A few seconds will be sufficient for winding up the apparatus and will require
to be wound only four times for operating the sewing machine for a day.
This apparatus can be applied to any system of sewing machines.

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:
. An improved motor for sewing machines in which a group of springs A juxta-
posed on a cylindrical axle B are simultaneously wound by means of a crank
handle D and gear E H put in or out of operation by means of a lever F. The
said series of springs A operating the movement of the sewing machine by means
of toothed wheel H pinion I spur wheel J loosely mounted on axle K and gear-
ing L, M, N, O, Q, Q¹, the speed of the motor being controlled by a hand lever U
actuating a friction brake V operating on the wheel T substantially as described
and illustrated.
