The invention relates to Heilmann type comb
ers, being- a division of my application, Serial No.
359,385, filed October 2, 1940, Patent No. 2,353,812
to which reference may be had for any matter
herein shown but not described.
The object of the present invention is to irn
prove the supporting and control means, the op
eration and the convenience of use of the top
combs in combers of the kind referred to.
In the accompanying drawings Fig. l is a, gen
eral cross-section through a comber to which the
invention is applied; Fig. 2 a front elevation of
one of the combing heads thereof; Fig. 3 a cross
section of Fig. 2 in a plane adjacent to one of
the top comb arms, showing the top comb in sec
tion; and Fig. 4 is a top plan of Fig. 2 showing
also parts of the drive head.
It will be understood that in such a comber
there are ordinarily several combing heads of
which the operating parts are driven from the 20
the tuft from the lap still held by the feed roller
5 and pull it through the teeth of the top comb
I3 which has been lowered for that purpose. The
top-comb combs the tail ends of the fibers con
stituting the tuft as they are drawn forward by
the detaching rollers.
The detaching rollers receive the front end of
the tuft on top of the tail end of the preceding
tuft, with an appropriate overlap, thus píecing
the tufts together to form a continuous fleece
composed of a succession of imbricated tufts.
For this purpose the rollers are given an alter
nate forward and backward rotation, referred to
as the píecing motion. In their forward motion
they detach the tuft, as just stated and in their
backward motion they return and expose a con
siderable length of the rear ends of the fibers in
position to be overlapped by the next-arriving
tuft. Ordinarily, also the axis of the top roll Il
is traversed forwardly and backwardly over the
top of the bottom roll l2, in synchronism with
drive-head, at the end of the machine, by means
of longitudinal shafts extending through al1 of
the intermittent rotation, so as to facilitate the

It is sometimes desirable to impart a quick 20
supporting arm, an oscillating support therefor,
downward movement to the top comb so as to
promote a positive penetration of itsv teeth into

present case by supplementary tracks`A adapted to

is in the form of a latch member, marked 1|,

the forward stroke and adapted tol fall off of it

ods of adjustment of 'ma couldbe provided, this
method is extremely delicate and at the same time

will be observed also that the whole top comb

combing head by turning the arms over and back
on the pivots of the cranks 55e, this being- a
special virtue of the rearwardly located hinge
