PROVISIONAL SPECIFICATION.
Improvements in Noble's Combs.
I, JOHN HENRY WHITEHEAD of the Firm of Taylor Wordsworth and Co.
Midland Junction Foundry, Leeds, in the County of York, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in circular combs or machines for
combing fibres, the object being to so construct such machines that the drawing off
rollers and leathers will wear evenly over their whole surface, and without hollows
as heretofore, and the invention consists in constructing machines in such a manner,
that the drawing off rollers, leathers, and gear plate, traverse or move up and
down or the drawing off rollers, leathers, and gear plate may be stationary, and
the fibre caused to traverse up and down the rollers and leathers, by causing the
rack and comb circle to rise and fall.
According to this invention, the drawing off rollers and leathers are mounted on
the ordinary gear plate, which is carried in slides formed in the feet of the machine,
and the said gear plate and the gear are by cam or eccentric, caused to rise and
fall in such slides. The cam or eccentric may be conveniently driven by a catch
or pawl on the hangers operating a ratchet wheel and worm, the latter driving a
wheel on a cross shaft, on which is the cam or eccentric.
The rack and comb circle may have the rising and falling motion imparted to it,
so as to cause the fibre to travel over the whole surface of the leathers and rollers,
and in this case the rollers, leathers, and gear plate remain stationary as ordinary.

1, JOHN HENRY WHITEHEAD, of the Firm of Taylor, Wordsworth and
Company Limited, Midland Junction Foundry, Leeds, in the County of York,
Machine Makers, 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 improvements in circular combs, or machines for
combing fibres, the object being to construct such machines that the drawing off
rollers, and leathers will wear evenly over their whole surface, and without hollows
as heretofore, and the invention consists in constructing machines in such a manner
that the drawing off rollers, leathers, and gear plate traverse, or move up and
down.
According to this invention the drawing off rollers, and leathers are mounted on
the ordinary gear plate which is carried in slides formed in the feet of the machine,
and the said gear plate and the gear, are by cam or eccentric caused to rise and fall
in such slides. The cam or eccentric may be conveniently driven by a catch or

wheel on a cross shaft on which is the cam or eccentric.
Such being the nature, and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings
in which :-
Fig. 1. is a plan view of the gear plate illustrating the apparatus for ensuring the
requisite traverse of the said plate, together with the drawing off rollers, the
drawing off leathers, the guide or stretching rollers, and the slide guiding pieces.
Fig. 2. is an elevation shewing the appliances for operating the gear plate, also
shewing the ordinary gear, and one pair of the drawing off rollers.
Fig. 3. is a detail.
At 1 is the gear plate supported at opposite sides by the forked slide piece 2, and
runner or bowl 3 on the eccentric 4, the latter being fast on the cross shaft 5, there
being similar slide pieces 2° 2° on the opposite sides, and as shewn in Fig. 1. The
contact surfaces c. d of the slides are of considerable length, so as to prevent any
tendency of the gear plate, when being traversed, to tilt and lock at its contact
points. The ordinary gear 6, and also one pair of drawing off rollers 7 to be lifted
are seen clearly in Fig. 2.
The shaft 5 of the eccentric 4 is driven by means of the catch lever 8 catch 9,
ratchet and wheel 10, worm 11, and worm wheel 12 so as by the runner or bowl 3,
and slide 2, to lift the gear plate 1, gear 6 drawing off rollers 7 and stretching
rollers 7ª, and other parts as described. The ratchet wheel 10 may be driven by
lever 8 such as illustrated, operated from an inclined foot a formed on one or more
of the several revolving hangers 6 (see detail) or said lever may be operated from
any convenient going part of the machine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what
1 claim is :-
:-
In a Noble's comb, a traversing gear plate, carrying and traversing the ordinary
gearing, the drawing off rollers and leathers, together with their guide rollers, said
plate being operated by means such as herein described, and illustrated by annexed
drawings.
