Improvements in Apparatus for Traversing the Drawing Off Leathers
on Combing Machines.
We, OLIVER BROOK LISTER, of Shetcliffe Mill, Dudley Hill, near Bradford, in
the County of York, Spinner, and HENRY BATTY, of the same place Mechanic, 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:-
This invention relates to certain improvements in apparatus for operating the
drawing off or carrying leathers used in combination with the drawing off rollers on
combing machines, and has for its object, the construction of the apparatus in such
a manner that, the carrying rollers and leather belt thereon are reciprocated in
the direction of the axis of the rollers in such a way that, the stoppage of the
reciprocating or traversing motion at the reversal of the same at each end of the
stroke is reduced to such an extent that, the cutting of grooves in the leather is
obviated, thus making the carrying leathers more durable than is the case when the
carrying rollers are operated in the manner as hitherto.
In the accompanying drawings
Fig. 1 represents an elevation of certain portions of a "Noble's" combing machine
with our improved traversing motion added thereto.
Fig. 2 is a plan of the same.
Figs. 3 and 4 are detached details showing the cam arrangement for giving the
necessary reciprocating or traversing motion to the carrying rollers and leather,
and
Fig. 5 a sectional plan through line a b.
The combing machine is driven and all the working parts operated in the usual
manner, except the carrying rollers A. A. A. which are made to reciprocate in a
vertical direction by a novel combination of parts.
In describing the invention reference is made to one set of drawing off rollers 3.
and carrying rollers, the set on the opposite side of the machine is indicated by
similar letters and constructed and operated in a similar manner.
On the revolving upright shaft C is secured a worm D gearing into a wheel E on
shaft F. upon which is also fixed a worm G gearing into and rotating wheel H.
secured upon the cam shaft J supported at one end by a bracket K and at the other
by a similar bracket L.
Upon the rotating shaft J. is fixed a cam M. the circumference of which is in
contact with a small roller N. supported by a stud O attached to the table plate P.
which is free to slide in a vertical direction in bracket L.
The table plate P supports the carrying rollers A. the spindles of the latter being
connected thereto by suitable adjustable slotted plates Q of the ordinary description,
so that whatever motion is given to the table plate P. is transferred to the carrying
rollers A. and leather belt R.
The cam M has a continuous rotary motion imparted thereto by the gearing
hereinbefore described, and by making the periphery of the cam pointed as at M
and with a pointed recess as at M somewhat in the manner as shown, the stoppage
in the reciprocation or traverse of the table plate P. and attachments thereto is
considerably reduced at the reversal of the stroke.
The carrying leather R is placed upon the rollers A. and passes between the
drawing off rollers B as hitherto, and by a uniform reciprocating motion being
imparted to the table plate P and having a quick return in the direction of motion
at each end of the stroke, the sliver of fibre as it is drawn from the comb circle U
does not cut grooves in the leather R. at each end of the stroke and thereby render
ED

page_text: the leather R useless for the purpose as is the case when operated in the manner as
hitherto.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is: :-
The combination of the carrying rollers A, carrying belt R and table plate P
with a rotating cam M having a pointed or quick curved periphery at M¹ and a
pointed or quick curved recess at M arranged and operated substantially in the
manner as shown and hereinbefore described.
