the Commissioners of Patents, with his Petition, on the 13th September
1858.
I, GUSTAVE FLAGEOLLET, Manufacturer, at Vagney, Departement des Vosges,
in the French Empire, do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN SELF-ACTING MULES," to be as follows:-
My self-acting mule consists of two loose pulleys, one of which is provided
with a groove and a cord. These two pulleys are placed upon the main shaft
whicli commands the cylinders and the spindles. The self-acting mule is
provided with a vertical shaft which may be placed at the length of any cradle
(cliarriot), that shaft is commanded by by the loose pulley furnished with a
groove, and it (the shaft) commands a horizontal shaft which passes under
the cradle, and which is of a greater length 'than the needle fall.
The vertical shaft only bears a gear which commands the horizontal shaft.
The horizontal shaft first bears a conical gear fixed upon it, and also a toothed
muff (manchon denté), upon which a. straight gear is also. fixed, which turns
loose, and likewise a second toothed muff which can work into the first, and
is able to act freely. This last muff during the egress of the cradle is free,
and is maintained in a neutral position by means of a little lever with a hook,
which must work only when the vertical shaft is put in motion by the counter
by which the spindles are stopped. When the cradle is out a conical gear
works into the small conical gear fixed upon the horizontal shaft. When this
gear has made a revolution it raises the hooked lever which is attracted by a
helical spring (ressort a boudin), which is fixed to a bar which also. passes

page_text: under the cradle, and is also fixed to a second bar by means of a small muff
with pressure screws (manchon a vis de pression). When the hook is free
it is attracted by the helical spring (à boudin), and. works into the first muff,
and turns loose on the shaft. The two muffs form one with the latter, and
rotate with it. The straight gear fixed on the first muff draws in its rotation
a small horizontal shaft provided with a friction apparatus, and a dentated muff
for the purpose of lowering the rod and turning the thread on the naked part
of the spindle. The cradle is traversed by a horizontal shaft, the interior
part of which is furnished with a muff; these two muffs are so disposed that
when the cradle has made its exit it is partly stopped. This shaft has two
other organs for the purpose of turning the thread on the spindles by means
of a vertical shaft fixed in the interior of the cradle, while its posterior part
has an excentric which gears with the vertical gearing only for the time during
which such an action is necessary..
On the barrel of the muff fixed to the shaft which passes through the
cradle there is a chain fixed at its other extremity to a little sector forming
one body with the rod. As this shaft revolves it winds up the chain above
mentioned round the circumference of the muff, and consequently compels the
rod to describe an arc, and to descend. The counter rod then becomes free,
and supports the thread. The rod has a lever, the other extremity of which
has a bar with a small hinge. This bar continually leans against a cordiform
excentric that gives the form to the bobbins by means of a bar provided_with
a spring. When the rod has taken all the tread. on the bare part of the
spindles, this bar comes to bear upon the exterior part of this cordiform
excentric by means of a spur; but when the spur has gone beyond the
exterior surface of the excentric, the bar which continually kept it leaning
against the latter having gone back a distance equal to the thickness of the
spur, it raises up by means of a lever, the bar to which the helical spring is
attached, which has geared with it two muffs fixed on the shaft which com-
mands the dépointage. This bar becomes then free; the spring puts the two
muffs out of gear, and becomes engaged in a dentated muff fixed behind the
cradle, and commanding a scroll for the re-entrance of the cradle. The cor-
diform excentric in givin the form to the bobbins is supported by a lever, which
by the means of a roller slides on a circular coping rail fixed under the cradle,
and making only one revolution during the whole course of the latter.
barrel fixed on the shaft which commands the spindles is in in communication
by means of a chain with a circular sector, which causes the spindles to
revolve during the entrance of the cradle, as is the case withe ordinary self-
acting mules.
