IMPROVED COMBING-FEED MECHANISM FOR CARDS AND SIMILAR WOOL WORKING MACHINES
Year: 1886

page_text: I Comte VITTOLD DE NYDPRÜCK of 8 Rue Van Orley at Brussels Belgium, do
hereby declare the nature of my invention for IMPROVED COMBING-FEED MECHANISM
FOR CARDS AND SIMILAR WOOL WORKING MACHINES to be as follows:-
The present invention has for its object to comb the wool which has to be worked
on cards or similar machines during its feeding in such a manner that the burrs or
thistles or such impurities which are entangled therein become disentangled while
slightly held exposed on the wool fibres which by combs are arranged parallely in
such a manner that when the wool is stretched upon the carding cylinder the burrs
or thistles may be doffed off with great ease this allows a very pure quality of
wool to be obtained and conduces to a great economy of work.
I employ a combing feed apparatus arranged in a suitable manner over the
endless web of a carding machine.
Also I employ a combing cylinder consisting of an outer cylinder and an inner
cylinder arranged eccentrically with regard to the outer cylinder which is composed
of two end plates upon which a certain number of bars of ✓ shaped section are
fixed by countersunk screws or in other suitable manner to form the periphery of
the said outer cylinder. Between each two bars longitudinally slots are reserved
through which the combs are allowed to project. The combs being of a suitable
size may be pivoted in any convenient way upon plates or discs a suitable number
of which are keyed upon the shaft. These plates form with the combs the inner
cylinder. The shaft and consequently cylinder is journalled in bearings situated
eccentrically with regard to the centre of cylinder which rotates on the annular
Blot of the disc firmly secured to the frame of the machine. The two eccentrically
arranged cylinders rotate simultaneously and at the same rate of speed. This is
effectuated by a suitable number of symmetrically arranged pins projecting from
the outer plates of the inner cylinder and engaging themselves in a like number
of corresponding holes in the inner sides of the plates of the outer cylinder so that
the rotary motion of shaft and thus of the inner cylinder is simultaneously com-
municated by the pins to the exterior cylinder. By the eccentric arrangement of
the combing cylinder its outer face is provided on one side with the needles or
points of the combs projecting gradually through the slots between the bars of the
outer cylinder while the opposite side is a plain curved surface formed by the outer
Paine 71

page_text: smooth faces of the bars between which the combs are still retained at this side
but without projecting over them. Through the pivoting of the combs upon the
circular plates they are enabled to follow easily the inclined positions which they
are caused to take periodically by the eccentric position of the two cylinders which
arrangement is of the highest importance in this device because it prevents combs
from breaking.
Feeding rollers of ordinary character are provided. Immediately behind is
adjusted a fluted roller the blades of which serve to press the wool between the
first combs projecting after the roller in order that the wool may be drawn out in
the most efficient manner. This fluted roller may be operated by spur wheels or
in another suitable manner. On the plain side of the combing cylinder is situated
a doffing roller provided with rubber or flexible blades.
The combing feed apparatus may be mounted over the endless web of a carding
machine, so arranged by pressing rollers as to serve simultaneously as a web for the
combing mechanism. The wool is taken up by the feed rollers which bring it to
the combing cylinder where it is drawn out in such manner that when the combs
enter the cylinder it remains upon the plain surface of the latter in the form of a
ribbon composed of parallel fibres which is easily removed by the rubber blades of
the roller throwing it again upon the endless web of the carding machine for
further working.
The combing feed apparatus is such as to ensure that the work to be effected by
the carding machine becomes only supplementary the thistles etcetera being so
thoroughly exposed upon the wool fibres that they may be doffed off by the card
without difficulty.

I Comte VITTOLD DE NYDPRÜCK of 8 Rue Van Orley at Brussels (Belgium) 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:-
The present invention has for its object to comb the wool which has to be
worked on cards or similar machines during its feeding in such a manner that the
burrs or thistles or such impurities which are entangled therein become disen-
tangled while slightly held exposed on the wool fibres which by combs are arranged.
parallely in such a manner that when the wool is stretched upon the carding
cylinder the burrs or thistles may be doffed off with great ease, this allows a very
pure quality of wool to be obtained and conduces to a great economy of work.
Figure 1 of the annexed drawings is a sectional view of the combing feed
apparatus which is arranged in a suitable manner over the endless web of a
carding machine which is partly shewn on the right side of the drawing.
Figure 2 is a partial longitudinal section of the combing cylinder.
This latter consists of an outer cylinder C and an inner cylinder C³ which is
arranged eccentrically with regard to the outer cylinder which is composed of two
end plates P¹ P¹ upon which a certain number of bars b of V shaped section, are
fixed by countersunk screws or in other suitable manner to form the periphery of
the said outer cylinder C¹. Between each two bars longitudinally slots are reserved
through which the combs p are allowed to project. The combs p being of a
suitable size may be pivoted in any convenient way upon plates or discs P³ a
suitable number of which are keyed upon the shaft T. These plates P2 form with
the combs p the inner cylinder C. The shaft T and consequently cylinder C² is
journaled in bearings situated eccentrically with regard to the centre of cylinder C¹
which rotates on the annular slot e¹ of the disc E firmly secured to the frame of
the machine. The two eccentrically arranged cylinders rotate simultaneously and
at the same rate of speed. This is effectuated by (say) four or a suitable number
of symmetrically arranged pins tttt projecting from the outer plates P2 P* of the
inner cylinder C² and engaging themselves in four or a like number of corresponding
holes e e e e in the inner sides of the plates P¹ P¹ of the outer cylinder C¹ so that
the rotary motion of shaft T and thus of the inner cylinder C is simultaneously
communicated by the pins tttt to the exterior cylinder C'. By the eccentric
arrangement of the combing cylinder its outer face is provided on one side with
the needles or points of the combs p projecting gradually through the slots between
the bars 6 of the outer cylinder C while the opposite side is a plain curved surface
formed by the outer smoothed faces of the bars 6 between which the combs are
still retained at this side but without projecting over them. Through the pivoting
of the combs p upon the circular plates P³ P2, they are enabled to follow easily the
inclined positions which they are caused to take periodically by the eccentric
position of the two cylinders C¹ C³ which arrangement is of the highest importance
in this device because it prevents combs from breaking.

page_text: a¹ a² a³ feeding rollers of ordinary character are provided. Immediately behind
is adjusted a fluted roller R the blades of which serve to press the wool between
the first combs projecting after the roller a¹ in order that the wool may be drawn
out in the most efficient manner.
This fluted roller may be operated by spur wheels or in other suitable manner.
On the plain side of the combing cylinder is situated a doffing roller R³ provided
with rubber or flexible blades. All the parts may be operated in the direction of
their arrows and at the required rate of speed by any suitable or convenient means.
The combing feed apparatus is mounted in the present example over the endless
web of a carding machine which is so arranged by pressing rollers as to serve
simultaneously as a web for the combing mechanism. The wool is taken up by
the feed rollers a¹ as a³ which bring it to the combing cylinder where it is drawn
out in such a manner that when the combs enter the cylinder it remains upon the
plain surface of the latter in the form of a ribbon composed of parallel fibres which
is easily removed by the rubber blades of the roller R' throwing it again upon the
endless web K of the carding machine for further working.
The described combing feed apparatus is such as to ensure that the work to be
effected by the carding machine becomes only supplementary work because the
thistles etcetera being so thoroughly exposed upon the wool fibres they may be
doffed off by the card without difficulty.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
'I claim is:
1. In a combing feed apparatus a combing cylinder provided on one side with
needles or dents or sets of combs while it is plain on the opposite side this being
obtained by the eccentric arrangement of a plain slotted cylinder C¹ with the
interior comb cylinder C³ as described.
2. In a wool combing cylinder consisting of two cylinders arranged eccentrically,
the pivoting of the combs in a suitable manner in order to be capable of following
the inclines involved by the said eccentricity as shewn and described.
3. The simultaneous action of the two eccentric cylinders C C by the com-
bination of pins tttt of the inner cylinder with the holes ee ee of the outer
cylinder as shewn and described.
4. The combination of the fluted press roller R¹ with the combing cylinder for
drawing out the wool as shown' and described.
5. The general arrangement or combination of parts forming the wool combing
feed mechanism as set forth.
