of Suffolk Agricultural Engineers and Copartners and JOHN DEVONSHIRE ELLIS
of the Atlas Works Sheffield in the County of York Engineer.-" IMPROVEMENTS
IN THE MANUFACTURE OF BEATERS FOR THRASHING MACHINES AND IN THE
APPLICATION OF THE SAME TO THE REVOLVING DRUMS OF SUCH MACHINES
"
Our invention has reference to the manufacture of ribbed reversible beaters of
rolled or pressed steel iron or other suitable material and to the application of such
beaters to the revolving drums of thrashing machines
And our invention consists in forming. the beaters with the operating ribs made
right-handed on one side or face and left handed on the other side or face instead
of forming them as at present with the ribs either right-handed or left-handed only
on one side the other side being flat or without ribs.
Beaters forined in this manner can be reversed on the drum when worn on one
side, and they can also be arranged thereon so as to present alternately right-
Landed and left-handed ribs to operate on the grain in the usual manner.
The said double faced beaters are or may be rolled into the required form, and
when so formed can be used interchangeably-And in order to apply such beaters

page_text: to the drum they are or may be fitted into metal chairs having their upper surface
hollowed out to receive the lower side or face of the beaters; a packing of paper,
papier maché, leather or other suitable material being inserted between the two
surfaces of metal.
The said chairs are secured to the discs of which the drum is composed and the
beaters are bolted or fastened to the chairs thereby dispensing with the ordinary
use of wood as a backing for the beater.
But, if preferred, the usual continuous wood backing suitably hollowed out on
the top surface might be employed to receive the said reversible beaters.
Or the said reversible beaters may be fixed to the drum in any other suitable
manner.

of the Atlas Works, Sheffield in the County of York Engineer " IMPROVEMENTS
IN THE MANUFACTURE OF BEATERS FOR THRESHING MACHINES AND IN THE
APPLICATION OF THE SAME TO THE REVOLVING DRUMS OF SUCH MACHINES
Our Invention has reference to the manufacture of ribbed reversible beaters of
rolled steel, iron or other suitable material and to the application of such beaters
to the revolving drums of threshing machines.
And our Invention consists in forming the said beaters with diagonal ribs on
both sides such ribs being by preference right handed on one side or face and left
handed on the other side or face, instead of forming them as at present with ribs
either right handed or left handed on one side only the other side being plain or
otherwise with right handed or left handed ribs twisted completely round them like
a screw.
Beaters formed in this manner can be reversed on the drum when worn on one
side, and they can also be arranged so as to present alternately right handed and
left handed ribs to operate on the grain in the usual manner.
The said double faced beaters are or may be rolled into the required form and
when so formed can be used interchangeably. And in order to apply such beaters
to the drum they are or may be fitted into continuous or intermittent metal chairs
bolted to the heads or discs of which the drum is composed, and having their upper
surface hollowed out to receive the lower side or face of the beaters, a packing of
paper, papier maché, leather or other suitable material being inserted between the
two surfaces of metal.-But if preferred the usual continuous wood backing suitably
shaped and hollowed out on the top surface might be employed to receive the said
reversible beaters.
Or the said reversible beaters may be fixed to the drum in any other suitable
manner
In order that our Invention may be fully understood and readily carried into
effect we will refer to the accompanying drawings in illustration of the same.
DESCRIPTION OF THE DRAWINGS.
Fig 1 is a transverse section shewing a reversible beater applied to a drum
Fig: 2 is an end view of the same Fig: 3 is a section showing another mode of

page_text: or on, a packing of paper or other suitable material being inserted between the
lower surface of the beater and the hollowed part of the chair at C.
These continuous chairs B B are bolted as required to the drum heads or
discs D. D. and they may be supported by cylindrical parting blocks or collars E E
around the bolts F. F. or the cavity beneath the chair may be entirely filled with
strips of wood of suitable shape.
Figures 1 and 2 shew another method of fixing the reversible beaters to the
drum by means of any suitable number of cast iron or other chairs B. B. bolted
to the drum heads or discs D. D. and having a continuous face plate G bolted to them
in order to afford the requisite depth of threshing surface.-Or strips of hard wood
suitably shaped and hollowed out and having the face plates G. G. bolted to them
may be used to serve either as continuous or detached chairs or packing pieces
between the reversible beaters A A and the drum heads or discs D D.
Having thus described the nature of our said Invention and in what manner
the same is to be performed we hereby declare that what we claim as of our
Invention is.―
First.—The manufacture of reversible beaters for threshing machines of rolled
or pressed steel iron or other suitable material and having ribs made right handed
on one side or face and left handed on the other side or face substantially as herein-
before described.
And Secondly: The application of such reversible beaters of rolled or pressed
steel, iron or other suitable material substantially as hereinbefore described to the
revolving drums of Threshing Machines.
In witness whereof we the said Richard Garrett Frank Garrett and John
Devonshire Ellis have hereunto set our hands and seals the twenty sixth day of
July in the year of our Lord One thousand eight hundred and eighty three.
