Improvements in Beater Machines for Cleaning and Opening
Textile Materials.
I THOMAS RODGERSON MARSDEN of 3 Barlow Street, Oldham, in the County
of Lancaster, Foreman Machinist, in the employ of Messrs. Platt Brothers &
Company Limited, of Oldham, Machinists, do hereby declare the nature of this
invention to be as follows:-
My invention relates principally to the machines used in the cleaning and
opening of cotton as for example to the machines of the scutcher class.
In such machines the cotton is fed forward by means of rollers and is acted upon
by a rapidly revolving beater whilst being held by the feeding mechanism usually
consisting of a pair of rollers as is well understood. For some qualities of cotton
it is advisable that the beater shall beat the cotton closely up to the nip of the
rollers whilst for other qualities less close action is desirable.
It would thus be advisable to mount the feed rollers so that they could be adjusted
nearer to or further from the beater axis, but this cannot be conveniently accom-
plished as the machines are now constructed.
I effect the adjustment by moving the beater shaft pedestals or bearing blocks.
The beater in its revolutions just clears the edge of a stripping rail which carries
parts of the casing and is a fixture.
As the machine has been hitherto constructed the movement of the beater
pedestals would bring the beater in contact with the said stripping rail or would
too greatly increase the clearance between the beater and such rail. To overcome
this difficulty I form the stripping edge upon a rail or plate which is in a separate
piece from the part which carries portions of the casing as aforesaid and I connect
this rail with the beater shaft pedestals so that the parts move together when the
beater is adjusted, or otherwise stated I form the ordinary rail in two parts a
stripping rail and a bearer and arrange for the separate adjustment of the
stripping rail.
The connection of the parts may be effected by adjustably securing the rail ends
to feet or parts extending from the pedestals or by extending the rail ends to the
pedestals and adjustably securing the parts together or by mounting the pedestals
and rail ends upon carriages or sliding shoes arranged to be adjusted by means of
screws which may or may not be connected across the machine. In a construction
which I have devised for the purpose each pedestal is connected with one end of
the said rail by means of a fixed screw which passes through an abutment piece
secured to the framing of the machine.
The pedestal can be adjusted by means of nuts bearing against the said abutment
piece. The clearer bar is also adjustable upon the screw by means of nuts. I
should plane the meeting faces of the bearer aud stripping rail and provide that
the bolting or securing of the bearer would firmly clamp the stripping rails.
The means for adjustment of the parts may be varied. I may dispense with a
direct connection of the pedestals with the stripping rail by providing that an
extension of one part shall be in contact with the other part so that when both
parts are loosened the moving back of the pedestals would move back the
stripping rail. The contact might be effected by means of adjustable screws
or stops.

Improvements in Beater Machines for Cleaning and Opening
Textile Materials.
I THOMAS RODGERSON MARSDEN of Number 3 Barlow Street, Oldham, in
the County of Lancaster, Foreman Machinist, in the employ of Messrs. Platt
Brothers & Company Limited, of Oldham, Machinists, 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 and accompanying
drawings
My invention relates principally to the machines used in the cleaning and
opening of cotton as for example to the machines of the scutcher class.
In such machines the cotton is fed forward by means of rollers and is acted
upon by a rapidly revolving beater whilst being held by the feeding mechanism
usually consisting of a pair of rollers as is well understood.
For some qualities of cotton it is advisable that the beater shall beat the cotton
closely up to the nip of the rollers whilst for other qualities less close action is
desirable.
It would thus be advisable to mount the feed rollers so that they could be
adjusted nearer to or further from the beater axis, but this cannot be conveniently
accomplished as the machines are now constructed.
I effect the adjustment by moving the beater shaft pedestals or bearing blocks.
The beater in its revolution just clears the edge of a stripping rail which carries
parts of the casing and is a fixture.
As the machine has been hitherto constructed the movement of the beater
pedestals would bring the beater in contact with the said stripping rail or would
too greatly increase the clearance between the beater and such rail. To overcome
this difficulty I form the stripping edge upon a rail or plate which is in a separate
piece from the part which carries portions of the casing as aforesaid and I connect
this rail with the beater shaft pedestals so that the parts move together when the
beater is adjusted, or otherwise stated I form the ordinary rail in two parts a
stripping rail and a bearer and arrange for the separate adjustment of the
stripping rail.
In order that the nature of my invention may be clearly explained I will refer
to the accompanying drawings which represent such parts of a scutching machine
as are necessary to the sufficient illustration of my invention.
In the said drawings Fig. 1 is a side elevation of one of the beater pedestals and
shows also the connection of the pedestal with the end of the rail upon which the
stripping edge is formed.
Fig. 2 is a cross section on the line A in Fig. 1.
Fig. 3 is a cross section of the stripping rail on the line B in Fig. 2 and the part
of the casing to which it is secured.
In Fig. 1a is the beater shaft pedestal, is the beater shaft, c is one end of the
improved stripping rail, and d is a part of the underframing of the machine.
In Figs. 2 and 3 c is the stripping rail, and e is the bearer which extends across
the machine and carries parts of the casing.
The pedestal a is mounted to slide in a straight line upon the planed top of the
underframing d, and in the example is guided by a downwardly projecting lip a².
A filboe or abutment piece is fixed to the top of the framing and through an
eye in this filboe a screw g passes and by one end is attached to the pedestal.
The other end of the screw passes through a groove in the end of the stripping

page_text: rail c.
The said screw is provided with lock nuts at h h upon the two sides of the
filboe. It will be seen that the pedestal can be slid upon the top of the under-
framing by turning these nuts in one direction or the other as may be required the
pedestal being thus adjusted so that the beater will work closer up to the feed
rollers or further from them as may be desirable. When adjusted the nuts are
tightened so as to lock the screw in position and the pedestal is further secured by
tightening the ordinary holding down bolts which do not appear in the drawing.
It will be understood that provision must be made for the sliding of these bolts
during the adjustment of the pedestal or the bolt holes in the pedestal feet may be
slotted.
The cranked end of the stripping rail is seated upon the top of the under-
framing and the end of the bearer e is formed with a cavity so as to enclose the
said cranked rail end as clearly shown in Fig. 2.
It will be understood that there is a construction corresponding in all respects
on each side of the machine. The meeting faces of the two parts c and e are
planed so that they can be firmly clamped together by means of a screw i which
passes through the two parts and is screwed into the underframing or by means of
an equivalent bolt and by means of intermediate screws which pass through slots
in the bearer e. When the screws are slackened the rail c is free to slide upon
the underframing whilst the bearer e remains at rest. The screw is provided with
a second set of lock nuts k k on each side of the rail end c. These nuts are only
acted upon when it is desirable to adjust the stripping edge c' with relation to the
beater. When the beater is to be adjusted with relation to the feed rollers the
pedestal holding down bolts and the screws are slackened. The position of
the two pedestals on the two side frames is then adjusted by means of the nuts h h
the connecting screw 9 causing the rail e to move with the pedestals so that the
relation of the rail with the beater is maintained. When the adjustment is effected
the nuts and the holding down bolts and the screws i i¹ are tightened.
I do not confine myself to the precise details as illustrated as the rail c may. be
connected with the two pedestals in any suitable manner so long as the relation of
the rail with the beater is maintained.
The connection of the parts might be effected by adjustably securing the rail
ends to feet or parts extending from the pedestals or by extending the rail ends to
the pedestals and adjustably securing the parts together or by mounting the
pedestals and ends upon carriages or sliding shoes arranged to be adjusted by means
of screws which might or might not be connected across the machine.
The means for adjustment of the parts may be varied.
I may dispense with a direct connection of the pedestals with the stripping rail
by providing that an extension of one part shall be in contact with the other part
so that when both parts are loosened the moving back of the pedestals from the
feed rollers would move back the stripping rail, and the moving of the pedestals
towards the feed rollers would allow of a corresponding movement of the stripping
rail.
The contact might be effected by means of adjustable screws or stops.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is.
1. The construction of parts of a scutcher or revolving beater machine for
textile material substantially as and for the purpose set forth and indicated.
2. In beater machines; the stripping rail'e capable of adjustment upon or below
the bearer e for the purpose set forth.
3. In beater machines; the stripping rail c capable of adjustment upon or below
the bearer e and connected with the beater pedestals so that all move together when
the pedestals are adjusted toward or from the feed rollers substantially as and
for the purpose set forth.
4. In heater machines the stripping rail c capable of separate adjustment upon

page_text: or below the bearer e and having parts in contact with the beater pedestals when
adjusted to working position substantially as and for the purpose set forth.
