Year: 1873

page_text: LETTERS PATENT to Robert Wittig, of Chemnitz, in the Kingdom of
Saxony, Germany, Engineer, for the Invention of "IMPROVEMENTS IN
DIVIDING APPARATUSSES ON CARDING MACHINES."
Sealed the 13th May 1878, and dated the 28th January 1873.
PROVISIONAL SPECIFICATION left by the said Robert Wittig at the
Office of the Commissioners of Patents, with his Petition, on the
28th January 1873.
I, ROBERT WITTIG, of Chemnitz, in the Kingdom of Saxony, Ger-
many, Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN DIVIDING APPARATUSSES ON CARDING MACHINES," to be as
follows:-
This Invention relates to a method of arranging the dividing apparatus
upon wool combing machines and to appliances for retaining the neces-
sary tension upon
the fleece during the division.
According to my Invention the wool fleece as it leaves the card drum
is received immediately into the dividing apparatus, the purpose of which

page_text: is to separate the fleece into so many little threads of wool which are
then twisted into yarn.
The apparatus consists in the first place of two dividers, cach con-
sisting of so many separate small leather covered discs upon axles with
their fillets or flanges close together in rows; but in their periphery
the discs are at a distance from one another, the intermediate space
being exactly as large as the discs are broad. The position of the two
dividers is such that the discs are displaced, that is to say, the discs of
the one divider stand opposite the intermediate spaces left in the other,
moreover the discs stand pretty close to one another as the tangent.
Each of the two dividers axles supports a succession of lovers or the so
called "clavis (presser); these are in this case bent in the curvity of the
dividers and of the exact breadth of the discs on the dividers, or which is
the same thing, as broad as the intermediate spaces so as to fit into
these. The levers from one of the axles to which they are suspended
are carried into the intermediate spaces of the divider, and are on the
outside level with the periphery of the discs as far as the vertex of the
dividers; from there they run with their bends in opposite directions and
bear against the leather covered discs of the divider on which their
extremities rest. The levers on the other axle fit in the same manner
into the intermediate spaces of the divider exactly as the ones already
described, and run from the vertex with their bends in opposite di-
rections to the first set, so that they rest on the leather covered discs of
the other divider. The discs together with the pressers form in this
peculiar connection an entirety, the real dividing apparatus wherein the
discs are movable. The division is carried out in such a manner that on
the front side of the dividers where they are open, that is to say, where
the discs and levers run into one periphery the fleeco enters without
being prevented as far as the vertex. From there the division of the
flecco begins and follow the bends of the "clavis" running in opposite
directions, and are thus separated into as many threads of wool as thero
arc discs and "clavis." Each of the two dividers takes the half of the
wool threads in alternative succession and transports them by means of
the leather covered dises farther on the bright polished "clavis." Оц
the inner side of the dividers where the "clavis" cease are situated two
rollers consisting of separate furrowed discs which move near the
leather covered discs of the dividers, the threads of wool adhering to
them. These move with a somewhat slower circular motion than the
dividers so as to loosen the threads of wool for conveying. Above the

page_text: rollers are situated two smaller rollers, smooth or wrapped in leather,
according to circumstances, being also situated close before the discs of
the dividers, and through their revolving reversedly keep them clear to
a certain degree; besides that they assist the running off and on of the
threads of wool when the apparatus is set in motion. The further
course of the work is now confined to the twist (lay) of the threads of
wool, and to the hanking of the yarn, which is performed in the usual
manner.

Belonging to the dividing apparatus is further to be mentioned the
press" mechanism, namely, not only to assist the process of dividing,
but also the conveying of the threads of wool, a certain pressure in the
"clavis" is requisite. This pressure can either be brought about by
weights by attaching a counterpoise to cach separate clavis, or by
means of springs. The several clavis arc furnished with steel springs
which are tentered to press on the "clavis," and in this manner bring
about the pressure desired. The springs of cach divider are both affixed
to an axle within frames; to the spindles are affixed levers with
pressure bars, which are connected underneath with two weighted arms
so that the pressure on the "clavis can thereby be regulated.

filed by the said Robert Wittig in the Great Seal Patent Office on
the 25th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
WITTIG, of Chemnitz, in the Kingdom of Saxony, Germany, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

year of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Robert Wittig, Her special
licence that I, the said Robert Wittig, my executors, administrators,
and assigns, or such others as I, the said Robert Wittig, my executors,
administrators, and assigns, should at any time agree with,
others, from time to time and at all times thereafter during

page_text: vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN DIVIDING APPARATUSES ON CARDING MACHINES," upon the condition
(amongst others) that I, the said Robert Wittig, my executors or ad-
ministrators, by an instrument in writing under my, or their, or onc
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 Scal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that I, the said Robert Wittig, 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 statement thereof, reference being had to the Drawings
hereunto annexed, that is to say :—
This Invention relates to a method of arranging the dividing apparatus
upon wool combing machines and to appliances for retaining the necessary
tension upon the fleece during the division. The new dividing apparatus
for carded wool cards is represented in connection with the well known
parts of the carded wool card in the annexed Drawing, in four different
views. Figures 1 and 2 are the two side views, Figure 3 the ground
plan, and Figure 4 a vertical profile.
In the four views I. denotes tho doffer, and II. the comb (chopper) by
which the wool is taken from the doffer, and indeed, as fleece, as is the
case by every common carded wool card. The wool fleece III., Figure 4,
thus taken off comes immediately into the dividing apparatus in question,
the purpose of which is to separate the fleece into so many little threads
of wool which are then turned or twisted into yarn.
The apparatus consists in the first place of the two dividers Z and Y;
cach of the two dividers consisting of so many separate small leather
covered cast discs which are placed on the axles of the dividers with
their fillets close together in rows, but in the periphery of the discs arc
at a distance from one another, the intermediate space being exactly as
large as the discs are broad. The position of the two dividers is such that
the discs are displaced; that is to say, the discs of the one divider stand
opposite the intermediate spaces left in the other; moreover the discs stand

pretty close to one another at the tangent. Each of the two dividers
contains moreover its so called "clavis; " these are in this caso the cast-
iron levers X and W, being bent double in the curvity of the dividers
and of the exact breadth of the discs on the dividers, or which is the
same thing, as broad as the intermediate spaces so as to fit into these.
The levers X from the axle V to which they are suspended, are lifted
into the intermediate spaces of the divider Z, and are on the outside
level with the periphery of the discs as far as the vertex of the dividers,
Figure 4; from there they run with their bends in opposite directions,
and, as is to be expected, hit the leather covered discs of the divider Z, Y,
lying directly underneath; and on which they rest in their farther
The other levers W on the axle T fit in the same manner
into the intermediate spaces of the divider Y exactly as the ones already
described, and run from the vertex U with their bends in opposito
directions, so that they rest on the leather covered discs of the divider Z.
The discs together with the pressers form in this peculiar connection an
entirety; the real dividing apparatus wherein the discs are movable
but the "clavis" fixed. The division is carried out in such a manner
that on the front side of the dividers where they are open, that is to say,
where the discs and levers run into one periphery, the fleece enters
without being prevented as far as the vertex U. From there the
division of the fleece begins as they follow the bends of the clavis
running in opposite directions, and are thus separated into as many
threads of wool as there are discs and clavis. Each of the two dividers
takes the half of the wool threads in alternative succession, and tran-
sports them by means of the leather covered discs farther on the bright
polished "clavis." On the inner side of the dividers where the "clavis "
cease, are situated two rollers S and R consisting of separate furrowed
discs which move close before the leather covered discs of the dividers
respectively, the threads of wool adhering to them, and indeed with a
somewhat slower circular motion than the dividers, so as to loosen the
threads of wool for conveying. Above the rollers S and R are situated
besides two smaller ones Q and P smooth or wrapped in leather,
according to circumstances, being also situated close before the discs of
the dividers and through their revolving reversedly keep them clear to
a certain degree; besides that they assist the running off and on of the
threads of wool when the apparatus is set in motion. The further course
of the work is now confined to the "twist lay" of the threads of wool,
and to the hanking of the yarn, which is performed in the usual manner

page_text: and for which the parts O and N are used, and besides the yaru bobbins
(spools) M, L, K, and S.
"
Belonging to the dividing apparatus is further to be mentioned the
press mechanism, namely, not only to assist the process of dividing, but
also the conveying of the threads of wool, a certain pressure on the
"clavis" is requisite. This pressure can either be brought about by
weights by attaching a counterpoise to cach separate "clavis," or by
means of springs, the construction of which the Drawing shows.
According to it the several "clavis' are furnished with steel springs in
the form of H and G, Figure 4, which being tentered press on the
'clavis," and in this manner bring about the pressure desired. The
springs of each divider are affixed both to an axle as Fand E, which
aro both in frames, and end on the outside in a spindle. To the spindles
are affixed the levers D and C with their pressure bars D' and C', which
are connected underneath with the two-armed lever B, on which the
weight A is displaced, that is to say, the pressure on the "clavis" can
thereby be regulated.
"
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that what I claim
and desire to be protected by Letters Patent as my Invention is, the
dividing apparatus in, on, or to carding engines, as and for the
purpose set forth and shown in the accompanying Drawings.
In witness whereof, I, the said Robert Wittig, have hereunto set
my hand and scal, this Sixteenth day of July, One thousand
eight hundred and seventy-three.
