PATRICK KELLY of Bradford in the County of York Machine Wool Comber
IMPROVEMENTS IN COMBING MACHINERY
This invention relates to that class of machines known as "Listers Combs" and
has for its object the better adaptation of this well known machine to the combing
of wool of shorter fibre than the machine has been generally used for.
The first part of my invention consists of an improvement in the construction of
the intersecting comb, for which Letters Patent were granted to me in 1876 and
numbered 3469, and also in the mode of working the same.
The second part of my invention consists in the arrangement of the dividing
motion to suit the necessarily reduced traverse of the nip head on account of the
shortness of the fibre proposed to be combed on this class of machine.
The intersecting comb has been constructed hitherto by the insertion of fine flat
pins into the body of the brass on the curved angle of metal, whereas I now
propose to make the pins lay against the inside angle and secure the same to the.
metal by solder or brazing by this means I am enabled to construct finer combs,
having greater strength, as the wool is drawn from the teeth just below the metal
which supports the pins; thus giving them greater strength. I am also enabled to
use finer screws and fallers, thus concentrating the uncombed tuft into smaller
space than hitherto. The wool is thus better combed but the quantity so combed
is not so large as hitherto.
In order to overcome the drawback as to quantity I increase the speed of the
machine. This increased speed necessitates the ensuring of the action of the nip
cams which I accomplish by the introduction of two spiral springs operating
between the cross bar of the nip and the cross bar over the two tappet runners, and

tappets through the entire revolution. I also double the feeding heads, that is, I
have two feeders to one circle which I work with one shaft under the circle, from
each end of which I drive one of the heads.
The second part of my invention I accomplish in the following manuer :-Instead
of the studs upon which the dividing rod is worked being fixed to the frame of the
machine, it is carried by levers having motion imparted to them by tappets. In
this manner I am enabled to give a more vertical movement to the divider in much
less space.

IMPROVEMENTS IN COMBING MACHINERY
This invention relates to that class of machine known as "Listers Combs" and
has for its object the better adaptation of this well known machine to the combing
of wool of shorter fibre than the machine has been generally used for..
The first part of my invention consists of an improvement in the construction of
the intersecting comb, for which Letters Patent were granted to me in 1876 and
numbered 3469, and also in the mode of working same.
The second part of my invention consists in the arrangement of the dividing
motion to suit the necessarily reduced traverse of the "nip head," on account of the
shortness of the fibre proposed to be combed on this class of machine.
The intersecting comb has been constructed hitherto, by the insertion of fine flat
pins into the body of the brass on the curved angle of metal, whereas I now
propose to make the pins lay against the inside angle of the brass, and secure the
pins to the metal by solder or brazing; by this means I am enabled to construct
finer combs, having greater strength, as the wool is drawn from the intersecting
comb teeth just below the vertical or curved angle of the metal which supports.
the pins.
$
I also use finer screws and fallers; thus concentrating the uncombed tuft into
smaller space than hitherto. The wool is thus better combed, but the quantity so
combed is not so large as hitherto. In order to overcome the drawback as to
quantity I increase the speed of the-machine: this increased speed necessitates tho
ensuring of the action of the "nip tappets," which I accomplish by the introduction
of two spiral springs operating between the cross bar of the "nip-head" and the
angle plates over the two tappet runners, thus ensuring contact between-the
runners and the tappets throughout the entire revolution. I also double the
feeding heads, that is, I have two feeders to one circle, which I work with one
shaft under the circle, from each end of which I drive one of the feeding heads...

page_text: 1. The second part of my invention I accomplish in the following manner: Instead
of the studs upon which the dividing rod, is worked being fixed to the frame of the
machine it is carried by levers having motion imparted to them by tappets and by
rods in connection with the "nip" cross bar, in this manner I am enabled to give
a more vertical movement to the dividing bar in a much less space.
But in order to enable my improvements to be better understood; I will proceed
to describe the same by reference to the accompanying drawings. :
Figure 1 represents the outline of a "Lister's Combing Machine" to which my
improvements are added. Figure 2 is an enlarged sectional detail of my improved
intersecting comb shewing the fallers, brush, and nipping jaws, and Figure 3 is a
front-view of the "nip.head" shewing the additional spiral springs for keeping the
runners and tappets in contact.
The intersecting comb A is mounted in the usual manner, and the pins A¹ passing
through the wool, the comb when at the bottom of the stroke, the under edge of
the vertical angle of the metal supporting the pins, is, as near as practicable to the
wool whilst it is being drawn by the "nip head" from the fallers B through the
pins of the intersecting comb. By securing the pins to the angle plate in the
manner before described, the latter retains its full strength, not being cut away by
having to bore holes through for the reception of the pins. By these means I am
enabled to make combs much finer than hitherto, and "still retain the requisite
strength to withstand the drag of the wool through the pins: and the comb
having no shoulder on the inside, the bristles of the brush D can act and cleanse
the pins of fibrous material more thoroughly every time the comb A is withdrawn
from the wool.
"
The vertical motion of the intersecting comb is obtained by tappets E, and
runners F, constructed somewhat similar to those employed for actuating the "nip:
the rods G, connect the runners F, to the intersecting comb.
The main driving shaft is mounted in journals at the underside of the comb
circle H; to this shaft is secured a spur wheel, which gears into another wheel
mounted on shaft J, the latter having a pulley K, secured at each end which drive
respectively the two pullies K', and K' on feeding heads L, and L'.
By reason of the increased speed at which the machine is run, the runners are
liable to leave the tappets for a short time, and in order to ensure the runners M,
and tappets M', being in contact through the entire revolution, I introduce a spiral
spring P, at each side of the nipping apparatus, such springs being compressed
between the cross bar P¹, and the angle plates P2, to which the runners are secured:
all other parts of the "nipping" apparatus are ordinary.
The second part of my invention I carry into effect as follows: the motion of the
"nip head" to and from the fallers is communicated in the ordinary manner; the
connection between the cross bar P¹, of the "nip head" and the ordinary wheel is
shewn in the feeding head L, and at the other feeding head L' they are removed,
in order to better illustrate my new arrangement for working the dividing bar.
The shafts R receive motion from the main shafts R¹, on which the pullies K',
and K, are secured in the usual manner, and on the shafts R, at each side of the
machine, I secure an eccentric S, which on revolving and being in contact with a
small pulley S¹ on the end of lever T, causes the latter to oscillate on centre stud T'.
At the other end of each of these levers is secured a stud, on which is mounted a
short bell crank lever U; one arm of each of these last named levers, is connected
to the cross bar P₁ of "nip head" by a short rod V, and to the other arm of each
lever is secured the dividing bar.
It will be seen by persons conversant with combing machines, that the
eccentrics S, give a curved reciprocating motion to the end of levers T at T³,-and
at the same time the lever ends are descending, the "nip head" is travelling along
with the short rods V towards the comb circle H. These rods V, travelling towards
the comb circle, cause the bell crank levers U to turn on the studs, and the ends
at U to descend at a much quicker rate than the end of levers T, thus by this
compound motion, I am enabled to actuate the dividing bars in much less space

mounted in the ordinary manner.
Having thus described the nature of my invention, and in what manner the
same is to be performed, I hereby declare wliat I believe to be novel and original
and claim as the invention I desire to be secured to me by the hereinbefore in
part recited Letters Patent is:-
The construction of intersecting combs having the pins soldered or brazed to
the vertical angle of the metal in the manner and for the purpose described.
The combination of the levers with the eccentrics and cross bar of "nip head"
substantially in the manner and for the purpose as hereinbefore described.
The application of springs P between the cross bar and angle plates in the manner
and for the purpose as herein before described.
In: Witness whereof, I the said Patrick Kelly have hereunto set my hand
and seal this twelfth day of April in the year of our Lord one thousand
eight hundred and sighty-three.
