Specification Accepted, 4th May. 1889
I, GEORGE SMITH of Beck Street, off Leeds Road, Bradford in the County of York,
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:-
This invention consists in a nipping apparatus applicable to Nobles' or other similar
combing machines, for the purpose of partially drawing out the fringe of sliver from
the large comb before such sliver is taken off as noil by the small comb.
To carry out my invention employ a metal disc having leather, india-rubber, or
other suitable material fixed to its surface, such surface being on a level with the
bottom of the pins of the large circular comb, and revolving in a suitable dish fixed
to the comb table close up to the large comb, and a suitable distance from the small
taking off comb.
The disc is caused to revolve by means of the rack on the inside of the large comb,
which engages with a pinion fixed to the same shaft as the disc, to which shaft is also
fixed a bevil wheel resting on the surface of the disc. This bevil wheel engages with
another bevil wheel fixed to a shaft (working in suitable bearings secured to the comb
table) whose line of axis is at an angle to that of the shaft, herein before mentioned,
and projects towards the outside of the large comb. To the bottom part of this shaft
I fix a circular dome inside which the bevil wheel fits. The underside of this dome
comes in contact with the outer surface of the disc at that part nearest to the internal
periphery of the large comb, thereby nipping the fringe of sliver projecting and
slightly drawing it out preparatory for the small comb taking it off as noil.
The part of the dish hereinbefore mentioned nearest to the large comb is partly cut
away in order that the discs may maintain the nip long enough during their revolution
to draw the fringe of sliver partly out.
The sliver being operated upon is first dubbed into the large comb and then carried
to the nip by means of a dead plate over which it passes.
In order to enable this invention to be fully understood, I will proceed to describe
the same with reference to the accompanying drawings in which Fig. 1 represents a

Fig. 2 represents a plan of my improved nipping or drawing apparatus with top
nipper removed showing the lower disc and pinion in combing machine, and Fig. 3
represents a front elevation of the bottom disc showing the partly cut away portion
for the purpose of the two discs maintaining the nip long enough in order to draw the
fringe of sliver partly out.
Similar letters refer to similar parts in all the drawings.
The large comb is represented at A, the rack B of which engages with and drives
the toothed wheel fixed to the vertical shaft D to which is also fixed and revolves
with the sheet metal disc E, the leather or other suitable material disc F, and the
bevil wheel G which discs and pinion revolve upon the stationary disc H, which disc
is cut away at I in order that the top grip J coming in contact with the lower disc F
in their revolution may maintain a longer grip of the sliver. The top grip or dome J
is caused to revolve with the bottom grip or disc, by means of the bevil wheel G en-
gaging with and driving the bevil wheel K both being fixed to the same shaft L. The
top grip or dome J is kept at a suitable tension by means of the coiled spring N.
The fringe of sliver is prevented from curling up at the ends by means of the
stroker O actuated by the crank P fixed to the vertical spindle Q, which spindle is
caused to revolve by means of a pinion under the combing table.
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. The general construction and arrangement of an apparatus for drawing out the
fringe of sliver in machines for combing wool and other fibrous substances, substan-
tially as described and represented in the accompanying drawings.
