PROVISIONAL SPECIFICATION.
Improvements in Thrashing Machine Beaters.
We, ALFRED SHUTTLEWORTH and FRANK SHUTTLEWORTH, both of Stamp
End Works, Lincoln, Agricultural Engineers, and ROBERT GAMBLE, of Stamp
End Works, aforesaid, Machine Foreman, do hereby declare the nature of this
invention to be as follows:-
Thrashing machine drums have been constructed with beaters of various kinds.
One usual construction is with wooden beater bars having two surfaces at an obtuse
angle to one another these surfaces being faced each with a separate metal plate
one being plain and secured by ordinary screws to the wooden beater bar, the other
plate being formed with diagonally arranged ribs and being secured to the wooden
beater bar by bolts arranged in line with one another and with other bolts used to
fasten the wooden beater bars to the drum centre; the bolts used to fasten the
ribbed plates to the wooden beater bars have had to be made with heads having
portions of ribs thereon to supply the places of the portions of ribs removed in
forming through the ribbed plates the necessary holes for the passage of the
securing bolts. This construction is not altogether satisfactory: the wooden
beater bars are weakened by having so many holes through them in a row, there
is liability to splitting of the said bars and those ribs of the metal facing formed
partly by projecting portions of the bolt heads are not so smooth as is desirable for
satisfactory working.
Now to obviate the foregoing disadvantages according to this invention the
entire metal facing including both the plain portion and the ribbed portion is
rolled in one piece and the improved metal facing thus constructed is secured to
the wooden beater bar by bolts arranged at an angle to the bolts whereby the
wooden bar is fastened to the drum centre; the bolts that fasten the metal facing
pass only through the plain part of that facing and diagonally through the wooden
beater bar. By this improved construction the ribs of the metal facing forming
the thrashing surface are left entire and perfectly smooth, consequently brittle
grain is less likely to be split than with beater surfaces formed partly by the
ribbed heads of bolts.
This invention will enable beaters of increased strength and smoothness to
be produced more economically than beaters of the ordinary make already
referred to.

described and ascertained in and by the following statement :-
Thrashing machine drums have been constructed with beaters of various kinds.
One usual construction is with wooden beater bars having two surfaces at an obtuse
angle to one another these surfaces being faced each with a separate metal plate
one being plain and secured by ordinary screws to the wooden beater bar, the other
plate being formed with diagonally arranged ribs and being secured to the wooden
beater bar by bolts arranged in line with one another and with other bolts used to
fasten the wooden beater bars to the drum centres; the bolts used to fasten the
ribbed plates to the wooden beater bars have had to be made with heads having
portions of ribs thereon to supply the places of the portions of ribs removed in
forming through the ribbed plates the necessary holes for the passage of the
securing bolts." This construction is not altogether satisfactory; the wooden
beater bars are weakened by having so many holes through them in a row, there is
liability to splitting of the said bars, and those ribs of the metal facing formed
partly by projecting portions of the bolt heads are not so smooth as is desirable
for satisfactory working.
Now to obviate the foregoing disadvantages according to this invention, the
entire metal facing including both the plain portion and the ribbed portion is
rolled in one piece and the improved metal facing thus constructed is secured to
the wooden beater bar by bolts arranged at an angle to the bolts whereby the
wooden bar is fastened to the drum centre; the bolts that fasten the metal facing
pass only through the plain part of that facing and diagonally through the wooden
beater bar. By this improved construction the ribs of the metal facing forming
the thrashing surface are left entire and perfectly smooth, consequently brittle
grain is less likely to be split than with beater surfaces formed partly by the ribbed
heads of bolts.
This invention will enable beaters of increased strength and smoothness to
be produced more economically than beaters of the ordinary make already
referred to.
In the accompanying drawings,
Figs. 1 and 2 are respectively a cross section and front elevation showing a
portion of a wooden beater bar 1 secured to a drum centre 2 by bolts 3 and
provided with a metal facing which, according to this invention, comprises a
plain part 4 and a ribbed part 4ª rolled in one piece and secured to the bar 1 by
bolts 5 that pass only through the plain part 4 of the facing and diagonally
through the beater bar 1.
Fig. 3 is a similar view to Fig. 1 showing one of our improved metal facings
secured by bolts 5 to a rolled steel beater bed-plate 6 which is attached to the
drum centre 2 by other bolts 3.
Having now particularly described and ascertained the nature of the said inven
tion and in what manner the same is to be performed we declare that what we
claim is
The hereinbefore described improvements in thrashing machine beaters sub-
