HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. " IMPROVE-
MENTS IN CARDING MACHINERY." A communication from abroad by Jean Sebastien
Bolette, of Pepinster, in the Kingdom of Belgium.
The Invention consists in improved machinery for severing or forming into
ribands wool or other similar material as it passes or comes from the plain doffer of
a carding machine, such division being made by means of leather or other endless
bands, cords, or equivalents crossed in form of an 8 between two dividing rollers
and two smaller or driving rollers, these bands being in number equal to half the
number of ribands to be obtained and twisted between the dividing and the
driving rollers, and made to touch the rubbers. The wool passing between the
dividing rollers is divided by the bands running in opposite directions. Each band
takes two ribands, one downward, the other upwards. These ribands are formed
on the inside of the bands, but by the twisting of these bands they come outside
and in contact with the rubbers, by which they are taken and transformed into
slivers. Instead of bands equal in number to half of the slivers to be obtained, I
use a single band crossed between the above mentioned rollers in form of an 8 as
many times as necessary to form the same dividing arrangement as above described,
but as by this arrangement one end of the band is at one side of the rollers and
the other end at the other side, it is necessary to pass the two ends of the band on
two small suitable pulleys for carrying said ends in the same direction, which are
then united so as to form an endless band. By this arrangement all the parts of
the endless band pass successively and rapidly over all the rollers, and if some parts
of the band are of different breadth they cause no difference between the slivers.
The leather bands may be replaced by strings or cords passing into two small
grooves turned out in the surface of the dividing and driving rollers, two strings
operating like the sides of a strap to divide and drive the wool.

MENTS IN CARDING MACHINES." A communication from abroad by Jean Sebastien
Bolette, of Pepinster, in the Kingdom of Belgium.
This Invention relates to condensers or devices for severing into bands fleeces of
wool or other similar material as they are passed from the plain doffer of carding
machines. Hitherto this has been effected in various ways, and amongst others by
the employment of machinery consisting of rollers and several leather bands equal
in number to the fleece bands to be obtained. The Invention consists in making
such severance by means of bands formed by a single leather endless band passed
over and crossed between two rollers, which I call dividing rollers, and two smaller
rollers, which I call driving rollers, in such a manner as to form a series of figures 8
joined one to the other, and in number equal to half the number of bands it is
desired to work the fleece into, by which arrangement all parts of the endless band
pass successively and rapidly on all parts of the rollers, and if some parts of the
band are of different breadth to others they cause no difference in the slivers. In
the accompanying Drawing, in which similar letters of reference indicate like parts,
Fig. 1 is a side or end view, showing the new device fixed in position with reference
to the doffer X and the rubbers G of a carding machine; Fig. 2 is a front elevation
taken from the side of the doffer; Fig. 3, a front elevation of same taken from the
side of the rubbers; Fig. 4, a partial plan. E is the leather endless band in one
piece; B and C the dividing rollers; and D, D, the driving rollers; F are pulleys
or carrying rollers; H, the fleece to be divided to form slivers. In action, the band
E is twisted in Figure 8 fashion between the dividing and driving rollers, and
touches on its way the rubber G. The fleece passing between the dividing rollers
is divided by the band running in opposite directions, which takes two fleece
ribands, one downwards and the other upwards. These fleece ribands are formed
on the insides of the band, but by the twisting of said bands the ribands come
outside and in contact with the rubbers by which they are taken and formed into
slivers. The rubbers G may be put at the inside of the endless band, as shown in
Fig. 5, in which case the band must not be twisted between the rollers B and D,
and C, D. Claim: A condenser or device for severing woollen fleece or similar
materials into ribands, consisting of two dividing rollers B and C, combined with
two driving rollers D, D, together with a single endless leather band E passed and
worked over and between said dividing rollers, in such manner as to form a series
of bands disposed Figure 8 fashion, and double the number of the ribands to be
formed, all substantially as and for the purpose specified.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Seventeenth day of October, A.D. 1879.
