An Improvement in Beater Bars Used in Threshing Machines.
I, HENRY FERDINAND RICHARDSON, of Oaklands, Waldegrave Road, Teddington,
in the County of Middlesex, Agent, a communication from abroad from George
Woolnough, of Halberstadt, in the Kingdom of Prussia, Engineer, do hereby declare
the nature of this invention to be as follows:-
I roll or cast in Iron or Steel, or other suitable material, Beater Bars similar to
those now in general use, with the exception that the back or reverse side instead of
being flat, is provided with one or two rims extending the whole length of the said
Beater Bars. The object of these rims is that they shall overlap the edge or edges of
the Chair or Carrier to which the Beater Bars are attached by nuts and bolts, thus
protecting the said edge or edges from wear and tear.
I claim therefore that by the improvement above set forth, the Beater Bar alone is
subject to wear and tear, whereas when the Beater Bar has no protecting rim or rims,
both Beater Bar and Chair or Carrier are rapidly worn away.

An Improvement in Beater Bars Used in Threshing Machines.
I, HENRY FERDINAND RICHARDSON, of Oaklands, Waldegrave Road, Teddington,
in the County of Middlesex, Agent, 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:-
The beater bars used in threshing machines are usually fixed on chairs or carriers
attached to the periphery of the threshing drum, and when they become too much
worn they are removed, and new beater bars are substituted for them. The chair or
carrier also becomes worn especially at its front edge, and has to be removed to give
place for a new one.
The object of my invention is to provide against such wear of the chairs or carriers,
and this I effect by making each beater bar with a rim or lip at one edge or at each
edge projecting backwards so that when the beater is fixed in its place this rim or lip
projects over the edge or edges of the chair or carrier and protects it from wear.
Fig. 1 of the accompanying drawings is a transverse section and Fig. 2 is a part
plan of a beater bar according to my invention and its supporting chair or carrier.
A is part of the drum and B one of the carriers fixed on the drum in the usual way.
C is the beater bar which I make with lips or rims D D projecting over the edges of
the carrier B. The beater bar C might be made with a single lip or rim D at the
front or striking edge, but as it is often convenient to reverse the beaters when they
are partially worn, it is preferred to provide the lips or rims at both edges as shewn.
In other respects the beaters are similar to those generally in use, and, like them,
may be rolled or cast in steel or other suitable metal.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A beater bar for a threshing machine made with a lip or rim projecting backwards
at one or at each of its edges, substantially as and for the purpose set forth.
