Year: 1863

page_text: LETTERS PATENT to Felix Lepoutre, of Tourcoing, in the Departement
of the Nord, in the Empire of France, Manufacturer, for the Invention
of "A NEW MECHANICAL SECTOR APPLICABLE TO ALL SELF-ACTING MACHINERY
USED FOR SPINNING TEXTILE FABRICS."
Sealed the 7th January 1864, and dated the 17th July 1863.
PROVISIONAL SPECIFICATION left by the said Felix Lepoutre at the
Office of the Commissioners of Patents, with his Petition, on the 17th
July 1863.
I, FELIX LEPOUTRE, of Tourcoing, in the Departement of the Nord, in the
Empire of France, Manufacturer, do hereby declare the nature of the said
Invention for "A NEW MECHANICAL SECTOR APPLICABLE TO ALL SELF-ACTING
MACHINERY USED FOR SPINNING TEXTILE FABRICS," to be as follows:-
By the use of this new sector yarn may be taken off or given to bobbins
and to cops, conical and cylindrical, with regularity and according to require-
ment, in other words it may be increased or diminished at will.
The sector of my Invention is composed essentially of a rack turning
regularly and at the required speed, a crank, which raises and lowers the chain,
serving to distribute the yarn on the bobbin. This rack, be it understood, is
calculated and constructed so as to furnish yarn for every combination, that is
to say, by the different arrangements of which it is susceptible, or by the speed
which may be given to it, it may be applied to all the requirements of spinning.
It is set in motion by the guide, and that by means of the crank enclosed

page_text: within the carriage, aided by a catch and small rack. By the use of this catch,
when the rack. gives too much yarn, as much as is desirable is regularly taken
off, and thus the yarn always has an equal and uniform tension. In one word,
without boring and without cutting, I am enabled to form bobbins, so to say,
mathematically. As will be seen in reference to the annexed Drawing, forming
part of this my Provisional Specification, this arrangement works without cords,
friction, or differential movement, and without manual labour. The parts in
front of the carriage T are, A, yarn lowerer; B, pin attaching the rod C to A;
H, wheel commanding the sector; X, support of wheel II; K, rack which
causes the fork L to travel; L, fork attached to the upper rack, and carrying
the catches M; M, catches moving the ratchets O; N, support of rack. The
pieces adapted to the sector U are, V, scrow of the sector; Q, bevil wheel,
which turns the screw of the sector; P, bevil wheel commanding the wheel Q,
O, ratchet turning the wheel P; Y, spindle of the wheel P. The pieces
working within the carriage are, C, rod working the crank D; D, crank
on the shaft; E, small pins on the rod C for moving the crank D; G, shaft
on the wheel H; J, support or bearing of shaft; I, small friction pulley on
shaft G; R, pin of the rod C; S, cross piece in the carriage.
To obtain bobbins the catch M is used by the rack A', which is screwed on
the fork L, and the ratchet O which is on the wheel P by the pinion Z.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Felix Lepoutre in the Great Seal Patent Office on the
18th January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FELIX
LEPOUTRE, of Tourcoing, in the Departement of the Nord, in the Empire of
France, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of July, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Felix Lepoutre, Her special licence that I, the said Felix Lepoutre, my
executors, administrators, and assigns, or such others as I, the said Felix
Lepoutre, 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
yend, within the United Kingdom of Great Britain and Ireland, the Channel

page_text: Islands, and Isle of Man, an Invention for "A NEW MECHANICAL SECTOR
APPLICABLE TO ALL SELF-ACTING MACHINERY USED FOR SPINNING TEXTILE FABRICS,"
upon the condition (amongst others) that I, the said Felix Lepoutre,
my exccutors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly 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 immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Felix Lepoutre, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment, reference being had to the Sheet of Drawing hereunto annexed, and
forming part of this my Specification, and to the figures and letters of
reference marked thereon.
The use of this sector offers many advantages; it not only suppresses the
work of the workman, thereby effecting an important saving in manual labour,
but also, while permitting the formation of irreproachable conical or cylindrical
cops, it gives or takes off the yarn, regulating it according to the requirements
of the work.
I will first set forth the principal parts of which this sector is composed, and
I will afterwards explain its action. T, T', chariot or carriage; A, yarn
lowerer; R, bobbin on which the yarn must wind; B, pin attaching the rod C
to the yarn lowerer; H, wheel commanding the rack of the fork; X, support
of the wheel H; K, rack which causes the fork L to travel, and governed by
the wheel H; L, L', fork attached to the rack and carrying the catch M; M,
catch moving the ratchet O; N, support of the rack; U, sector; V, screw of
sector; W, support of screw of sector of the ratchet pinion and conical wheels
governing the screw; Q, bevil wheel, causing the screw of the sector to turn;
P, bevil wheel commanding the wheel Q; O, ratchets, causing the wheel P to
work to draw off yarn, and O', pinion, causing the wheel P to turn in contrary
directions to give yarn; Y, shaft of the wheel P; C, rod working the crank D;
D, crank on the shaft G; E, E', small friction rollers or pins communicating
motion to the crank D; G, shaft of the wheel II; J, support or bearing of
the shaft G; F, nut sliding in the column S; S, column enclosing the screw
governed by the wheel Q; Z, rack fixed on the fork and governing the
pinion O¹.
I will now describe the movements and the operations of this new sector.
The yarn on leaving the spindle of the spinning machine passes in the varn

page_text: lowerer A and winds on the bobbin R. On the yarn lowerer A and at the
joint B is fitted the rod C, which receives an alternate rectilineal motion.
This rod carries two friction rollers E, E', which may be brought closer together
or set further apart by means of small recall screws placed on clutch boxes
sliding on them and intended to regulate their distance apart. These two
friction rollers communicate to the crank D fixed on the shaft G an alternate
circular motion. This shaft carries at its end a toothed wheel H, which has
the same motion as the crank D; this wheel gearing with the rack K fixed on
the fork Z and L' communicates to this latter an alternate rectilineal motion.
While all these movements are taking place the carriage travels as usual, so
that the catch M and the rack Z of the fork pass successively, the first on the
ratchet O, and the second under the pinion O'. It will be understood that in
this movement, if the fork L, L', has taken the position indicated, Figure 7,
the ratchet will have a rotary motion during the whole time the carriage is
travelling; in the second case, the fork having taken the position indicated,
Figure 8, it will be the rack Z which will communicate a rotary motion to tho
pinion O'. The catch acting above the axle Y and the rack beneath, these
two movements will be contrary, and cousequently the wheel P which carries
at its boss the catch O, and the pinion O¹ will receive an alternate circular
motion, which it will transmit to the wheel Q, which is fixed on the screw V.
This latter carries a nut F guided by two grooves cut in the column S; the nut
will rise or fall in this column accordingly as the screw turns right or left, and
thus the yarn will be more or less stretched according to its position on the
screw and the inclination of the column, consequently the bobbin may be
tightened and regularly formed without it being necessary to regulate the
yarn by hand.
In witness whereof, I, the said Felix Lepoutre, have hereunto set
my hand and seal, this Eighth day of January, in the year of our
Lord One thousand eight hundred and sixty-four
FELIX LEPOUTRE. (L.S.)
