PROVISIONAL SPECIFICATION.
Improvements in connection with Automatic Feeders of Machines for
Opening and Cleaning Fibrous Materials.
I, BENJAMIN ALFRED DOBSON, of Kay Street Works, Bolton, in the County of
Lancaster, Engineer, do hereby declare the nature of this Invention to be as
follows:-
This invention relates to improvements in stripping or evening rollers employed
in automatic feeders of machines for opening and cleaning cotton and other
fibrous materials and is designed to effectually clean the pins or teeth of such
rollers, such pins or teeth having no protruding and receding motion.
In carrying this Invention into effect the pins or teeth are formed with or
attached to bars extending the length of the roller these bars being fixed to levers
pivoted to a disc made fast upon the shaft of the roller, the roller casing preferably
being mounted and revolving upon eccentrics or cams.
In operation and as the roller revolves, the pins or teeth receive an oscillating
motion due to the difference in the circumferential speeds of the roller casing
and the pins or teeth this being effected without forming slots in the roller casing
which slots are objectionable.
The roller casing and the shaft may be driven independently of each other
by any suitable means or the roller casing may be driven by means of the pins or
teeth.

Improvements in connection with Automatic Feeders of Machines for
Opening and Cleaning Fibrous Materials.
I, SIR BENJAMIN ALFRED DOBSON, Knight, of Kay Street Works, Bolton, in
the County of Lancaster, Engineer, 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 stripping or evening rollers employed
in automatic feeders of machines for opening and cleaning cotton and other
fibrous materials and is designed to effectually clean the pins or teeth of such
rollers, such pins or teeth having no protruding and receding motion.
In carrying this Invention into effect the pins or teeth are formed with or
attached to bars extending the length of the roller these bars being fixed to levers

page_text: pivoted to a disc made fast upon the shaft of the roller, the roller casing preferably
being mounted and revolving upon eccentrics or cams.
In the accompanying Sheet of Drawings-
Figure 1 is an end elevation and Figure 2 a sectional elevation of a stripping
or evening roller constructed according to my improvements.
In these views,-a designates the roller shaft or axle, b a disc or collar fixed
on the shaft and to which are pivoted the levers c which carry the bars d provided
with the pins or teeth e. The roller casing f has holes formed in its periphery
corresponding with the series of pins e and the boss of the casing is mounted at
each end (one only being shown in Fig. 2) on an eccentric bush g loose on the
shaft a; the eccentric g is keyed to a stationary bracket g¹ secured to the framing,
and the boss of the casing f is journalled in a bearing formed to receive it in
a stationary bracket h.
The shaft a is driven from a gear i and the roller casing f is driven at the same
speed from a gear j fixed upon it, or any other suitable means of driving may be
employed.
In operation, and as the roller revolves, the roller casing f having holes the size
of the pins for them to project through and being mounted on the eccentric
bushes g moves to and from the axis of the shaft a and so cleans the pins or
teeth e this being effected without imparting a reciprocating motion to the pins or
teeth e (which have only a slight oscillating movement) and without forming
slots in the roller casing f which slots are objectionable and liable to become
choked.
Having now particularly described and ascertained the nature of my said
invention and what manner the same is to be performed I declare that what
I claim is:
In a stripping or evening roller for the automatic feeders of opening and cleaning
machines
1. The combination with a revolving perforated roller casing having a recipro-
cating motion to and from the roller axis, of pins or teeth carried by bars mounted
on levers pivoted to collars on the roller axle said pins or teeth having no recipro-
cating motion of their own but being stripped by the reciprocating movement of
the roller casing substantially as and for the purposes herein set forth.
2. The general combination and arrangement of parts embodying my improve-
ments substantially as and for the purposes herein described with reference to
the accompanying Drawings.
Dated this 31st day of August 1897.
