PROVISIONAL SPECIFICATION.
Improvements in Rotary Combs in Automatic Feeders for Opening,
Cleaning, and Preparing Cotton or other like Materials.
I, GEORGE HORROCKS, of Kay Street, Stalybridge, in the County of Lancaster,
Machinist, do hereby declare the nature of this invention to be as follows :-
This invention relates to machinery for opening and cleaning cotton, in which
rotary combs that are constructed with teeth which recede into, and protrude
from, a cylinder at intervals during the revolution of said rotary combs, are
employed.
The objects of this invention are to affix the teeth in a rotary comb cylinder as
herein before described, so that said teeth may move inwards and outwards with
facility, and to regulate or adjust the distance of said rotary comb cylinder and
teeth from the lifting apron.
To effect these objects, I construct a rotary comb by means of a cylinder such
as a shown in transverse section on the accompanying drawing, in which the comb
teeth are connected at their inner ends to links e, said inner ends of teeth
sliding in grooves d formed within the cylinder: The inner ends c¹ of the aforesaid
links c are connected to a hoop or bande working on an eccentric that is placed
on the shaft g. The shaft g is free to revolve within the aforesaid eccentric, but
rotates the cylinder a.
By these means when the shaft g revolves, the aforesaid teeth are alternately
moved in a direct line to or from the centre of the cylinder inwards or outwards.
In order to adjust the position of the cylinder and teeth relatively with the
lifting apron, the ends of the shaft g are mounted in bearings that are caused to be
moved backwards and forwards in a slide, placed at right angles to the lifting apron
and actuated by an eccentric; by these means when said eccentric is turned, the
shaft with the rotary comb thereon is placed nearer to or farther from the
aforesaid lifting apron.

Improvements in Rotary Combs in Automatic Feeders for Opening,
Cleaning, and Preparing Cotton or other like Materials.
I, GEORGE HORROCKS of Kay Street, Stalybridge, in the County of Lancaster,
Machinist, 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 machinery for opening and cleaning cotton or other
fibrous substances, in which rotary combs that are constructed with teeth which
recede into, and protrude from a cylinder at intervals during the revolution of said
rotary combs, are employed.
The objects of this invention are to affix the teeth in a rotary comb cylinder as
herein before described, so that said teeth may move inwards and outwards with

page_text: facility, and to regulate or adjust the distance of said rotary comb cylinder and
teeth from the lifting apron.
I attain these objects by the means hereinafter described and as illustrated in the
accompanying three sheets of drawings, in which
Fig. 1 is a side view of a part of a feeding machine for opening, cleaning and
preparing cotton, with my invention applied.
Fig. 2 is an end view of the rotary comb drawn through line A A Fig. 3.
Fig. 3 is a longitudinal section of a part of said rotary comb.
In these views similar letters refer to similar parts.
In this invention I construct a rotary comb by means of a cylinder such as a
shown on the accompanying drawings, in which comb teeth as bor teeth of other
preferred form are connected to slides that are fitted to slide within the grooves d
formed in the arms a' of the aforesaid cylinder a. The slides are actuated by
means of the links e that are connected thereto by the pins c'. The inner ends of
the links are connected to a loop or bande working on an eccentric that is
placed on a shaft y. The shaft is free to revolve within the aforesaid eccentric
but rotates the cylinder a by being keyed on or otherwise secured to the boss a².
By these means when the shaft y revolves the aforesaid teeth are alternately
moved in a direct line to or from the centre of the cylinder, inwards when away
from the lifting apron and outwards when in proximity thereto. The stops c² assist
to retain the links c in position.
In order to adjust the position of the cylinder and teeth relatively with the lifting
apron, the ends of the shaft y are mounted in bearings that are fitted at each side
of the frame m and are caused to be moved backwards or forwards in a slide /,
placed at right angles to the lifting apron, by means of eccentrics / fitted on each
end of a shaft q. By these means when said eccentrics are actuated by the
handle attached to the shaft qg, the shaft g with the rotary comb thereon is
placed nearer to or farther from the lifting apron. Each of the aforesaid
bearings is when set in position firmly retained by the bolt which is passed
through the slot j².
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1st. In machinery for opening, cleaning, and preparing cotton or other like
materials, and which rotary combs are employed that are constructed with teeth
which recede into and protrude from a cylinder at intervals, the mechanism by
which said teeth are caused to be moved in a direct line inwards towards the centre
of the cylinder when away from the lifting apron, and outwards in a direct line
from the centre of the cylinder when in proximity to the lifting apron, in the
manner substantially as herein before described.
2nd. In machinery for opening, cleaning, and preparing cotton or other like
materials, and in which rotary combs are employed that are constructed with teeth
which recede into and protrade from a cylinder at intervals, the mechanism for
adjusting the position of the cylinder and teeth relatively with the lifting apron,
substantially as herein before described..
