I WILLIAM RICHARDSON of Hartford Works Oldham in the County of Lancaster
Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN
THE BEATERS USED IN THE MACHINES KNOWN AS SCUTCHERS OR OPENERS AND
USED FOR OPENING COTTON AND OTHER FIBROUS MATERIALS and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention relates to the beaters employed in the machines known as scutchers
or openers and used for opening and cleansing cotton and other fibrous materials
and consists in an improved method of constructing the said beaters by which
improved method of constructing the said beaters such beaters are rendered better
adapted for acting upon the cotton or other fibrous material to open and distribute
such cotton or other fibrous material upon the cages of the scutchers or openers in
which the beaters above mentioned are employed and by which improved method
of constructing the said beaters I simplify the construction of such benters and
render them capable of being more easily repaired than they have hitherto been.
In order that my invention may be fully understood and readily carried into
effect, I will now proceed to describe the same with the aid of the drawing hereunto
annexed in which drawing Fig. 1 is a side view partly in section and Fig. 2 an end
view of a beater constructed according to my invention. a. is the shaft or axle of
the beater upon which axle a. are mounted discs bbbb each provided with a
boss b¹ which discs bb bb are each secured upon the shaft or axle a by means of
a key c as shown or by any other suitable means-The discs bb bb jointly carry
a number of blades or bars dddddd which blades or bars dddddd are
similar to each other in construction.
As the blades or bars d d d d d d are similar to each other in construction I will
for convenience describe but one of such blades or bars d d d d d d and to the
corresponding parts of all such blades or bars dddddd I shall affix corresponding
letters of reference. I form the base A B of the blade or bar d of greater width
than the upper part CD of the said blade or bar d and in the edge of the each of
the discs bbbb I form a recess which I make of a form corresponding with that of
the blade or bar d. and in which recess I place the said blade or bar d. The parts
of the discs b b b b which overlap the edges of the blade or bar & serve to secure

page_text: such blade or bar d to the discs b b b b after the manner of dovetails. The blade
or bar d is prevented from moving longitudinally by means of screws e e e e which
pass through the blade or bar d and are screwed one into each of the discs bbbb
respectively as shown the screws e also assisting in securing the blade or bar d to
the discs bbbb.
The blades or bars dddddd may be formed with projections or teeth fas
shown, or in any other suitable manner or such blades or bars d d d d d d may be
plain and without teeth or projections or may be of any required form.
When any one or more of the blades or bars dddddd becomes or become
worn or injured the worn or injured blade or bar or blades or bars may be readily
removed from the discs b b b b after the screws which prevent such blade or bar or
blades or bars from moving longitudinally have been removed and after repair the
said worn or injured blade or bar or blades or bars may be replaced in position
upon the said discs bb bb or a fresh blade or bar or blades or bars may be
substituted for the worn or injured blade or bar or blades or bars removed.
In the drawing hereunto annexed is shown a beater having six blades or bara
carried by four discs but I would have it understood that a greater or less number
of blades or bars may be employed and a greater or less number of discs may be
used if desired.
In beaters as ordinarily constructed arms are employed to carry the blades or
bars of such beaters and the said arms in rotating cause currents of air which
interfere with the efficiency of the machines in which the said beaters are employed
By the employment of the discs b b b b for carrying the blades or bars d d d d d d
I avoid the production of currents of air and thus avoid interference with the
efficiency of the machines in which beaters constructed according to my invention
are employed.
Beaters constructed according to my invention are simpler and cheaper to
construct are more rigid and are capable of being more easily and readily repaired
than beaters as hitherto constructed.
I would have it understood that I do not confine myself to the precise arrange-
ments above described and shown in the drawing hereunto annexed as such
arrangements may be varied without departure from the principles of my invention.
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. In beaters to be used in the machines known as scutchers or openers the
discs bb bb for carrying the blades or bars d d d d d d of such heaters and
constructed arranged used and holding and secured to the said blades or bars
substantially as herein before described in reference to and shown in and by the
drawing hereunto annexed.
2. The mode of attaching and securing the blades or bars of the beaters used
in the machines known as scutchers or openers to the discs of the said beaters
substantially as herein before described in reference to and shown in and by the
drawing hereunto annexed.
