Improvements in Wool Combing Machines.
1, THOMAS KENNEDY of 569 North Twenty-fifth Street in the City of Philadelphia
State of Pennsylvania United States of America, Wool Comber 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 object of my Invention is to provide an improved arrangement in substitution
for the usual dabbing brush used for causing engagement of the wool with the teeth
of the rotating cam rings or circles of a wool combing machine, and this object I
attain in the manner hereinafter set forth reference being had to the accompanying
drawings in which Figure 1 is a side elevation partly in section, of sufficient of a
wool combing machine to illustrate my Invention. Figure 2 is a sectional plan view
of part of the machine (the section being taken on the line 1-2, Figure 1) Figure 3
is an enlarged sectional diagram illustrating the operation of that part of the machine
to which my Invention particularly relates and Figure 4 is a transverse section of
part of the machine.
In Figure 1, A represents one of the fixed posts or columns of a wool combing
machine, having at the upper end a hearing for a driving shaft B provided with a
belt pulley a and beli a' from which drives a pulley which is free to turn on a
spindle & carried by the post A and by an arm or hanger d secured to the post. This
pulley usually operates a vertically reciprocating dabbing brush for pressing the
wool into the teeth of the inner and outer rotating toothed circles or rings of the
machine, which are shewn respectively at F and F in Figure 2.
The use of a reciprocating dabbing brush is objectionable, however, partly on
account of its action upon the wool but mainly because of the jarring of the machine
duo to the reciprocating motion a result of the use of the reciprocating dabbing
brush being that the speed of the machine is necessarily limited in order to prevent
undue vibration.
In carrying out my Invention, therefore 1 substitute for the reciprocating dabbing
brush a feed belt for pressing the wool downward into the teeth of the comb rings
and a pressing shoe having inclined or hevelled bars or plates for supplementing the
action of the feed belt and completing the pressure of the wool into engagement with
the comb teeth.
The pressing shoe shown in the drawing is composed of two parts G G¹, the part
operating in conjunction with the teeth of the outer ring or circle F of the machine,
and the part G acting in conjunction with the teeth of the inner ring or circle F¹ of
the machine, both parts of the shoe being carried by the forked lower end of the
arm d depending from the column or post A.
The feed belt is driven by a roughened or corrugated roller ƒ into contact with
which it is pressed by an upper roughened or corrugated roller f' the bearings for the
shaft of which are acted upon by a set screw g the shaft of the driving roller having
a spur wheel h which engages with a pinion i on a shaft having
engaging with a pinion m¹ on the hub of the pulley b.
aspur wheel m
The lower portion of the feed belt z passes around a roller n carried by a stud
boli n' secured to an arm I which is connected to the post or column A, the roller n
being situated immediately in advance of the pressing shoe and the belt a being of
such a width and so situated as to overlap both the outer ring or circle F and the
inner ring or circle F' of the machine to the desired extent as shewn in Figure 2.
Each pressing shoe has a series of ribs s extending down between the circumferential
rows of teeth c on the ring or circle in conjunction with which the pressing shoe
operates, these ribs having a circumferential coniour similar to that of the toothed
ring.

page_text: As the rings rotate, therefore, the laps of wool extending radially inward over the
rings are first acted upon by the feed belt which extends down into close proximity
to the tops of the teeth as shewn in Figure 3 the consequence being that the laps of
wool are pressed down onto the teeth and are carried forward by the latter so as to
come under the influence of the inclined or bevelled ribs s of the pressing shoe by
which the wool is still further pressed down onto the teeth, so that the latter will have
a proper hold upon the same when the combing action is effected where the inner and
outer rings or circles diverge.
In order that the gearing for driving the belt a may be compactly arranged and
yot provide for a comparatively acute angle of the downward run of the belt so as to
cause it to act upon the wool gradually, I hang to the depending arm a bar the
outer end of which carries a roller serving as a guide for the belt, the bar t being
adjustable and fixable longitudinally on the arm I by means of a slot u and securing
bolt so that the angle of the downward run of the belt. . may he varied as desired.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is.
1st The combination with the toothed rings of a wool combing machine of a feed
belt for pressing the wool down onto the teeth of said rings and a ribbed shoe for
acting upon the wool after it leaves the feed belt and effecting the further pressing of
the wool down into the teeth substantially as hereinbefore described.
2nd The combination with the toothed rings of a wool combing machine of a
ribbed pressing shine, a belt for pressing the wool into the teeth of the combs before
it reaches the pressing slioe, a driving roll for the said helt, and lower and intermediate
carrier rolls for the belt substantially as hereinbefore described.
3rd The combination with the toothed rings of a wool combing machine of a bevel
ribbed pressing shoe, a feed belt, driving and carrier rolls therefor, and an adjustable
arm carrying an intermediate guide roll for the downward run of thic belt substantially
as hereinbefore described.
