page_text: I, WILLIAM DOYLE of Selskar Iron Works, Wexford, Ireland, Agricultural
Machine Maker, do hereby declare the nature of this invention to be as follows :-
This invention has reference to improvements in reaping and mowing machines
and is as follows:-
In the operation of this class of machines considerable resistance is encountered by
the finger bar in moving through the corn or other produce being operated upon, and
this resistance naturally exercises a tendency to force the finger bar out of its true
angular position and thereby seriously impare the efficiency of the machine.
The object of this invention is to provide means whereby this tendency may
readily and effectually be compensated, and the finger bar maintained in a constant
and proper angular position, in relation to the frame of the machine.
This object I accomplish by dealing with the tail end of the hinged shoe which
carries the finger bar.
For this purpose I fix on the said tail end of the hinged shoe, a suitable metal cap
provided with a square or circular shank which engages in a suitable horizontal
rectangular slot formed in a metal bracket, which bracket may be bolted to, or
constitute part of the casting of the main frame of the machine.
Through the inner end of this rectangular slot operates a screw bolt the point of
which impinges against the shank of the metal cap on the shoe end, so as to be
capable of moving same to and fro.
By this arrangement as the finger bar is forced out of its angular position the
hinged shoe end can be operated on by the bolt, and by thus throwing the shoe out
of parallel with the direction of motion the finger bar will be restored to its true
position.

I, WILLIAM DOYLE, of Selskar Iron Works, Wexford, Ireland, Agricultural Machine
Maker, 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 :-
This Invention has reference to improvements in reaping and mowing machines
and is as follows:-
In the operation of this class of machines considerable resistance is encountered
[Price 8d.1

page_text: by the finger bar in moving through the corn or other produce being operated upon,
and this resistance naturally exercises a tendency to force the finger bar out of its
true angular position and thereby seriously impare the efficiency of the machine.
The object of this Invention is to provide means whereby this tendency may
readily and effectually be compensated, and the finger bar maintained in a constant
and proper angular position, in relation to the frame of the machine.
For this purpose I fix on the tail end of the hinge shoe a suitable metal cap
provided with a square or circular shank which engages in a suitable horizontal slot
formed in a metal bracket, which bracket may be bolted to, or constitute part of the
casting of the main frame of the machine.
Through one end of this slot operates a set screw whereby the shank of the metal
cap may be moved as required.
The Accompanying Drawings will enable the nature and application of my
Invention to be more readily understood.
Fig. 1. is a front view of portion of a reaping or mowing machine shewing the
Application of my Invention thereto.
Fig. 2. is a side view of same with the near driving wheel removed, and
Fig. 3. is a side, and back view (enlarged) of my improved compensating
contrivance detached.
A, is the metal cap fixed on the tail end of the hinge shoe B, which latter carries
the finger bar C; D is the bracket provided with a horizontal slot in which the shank E
of the metal cap engages, and the horizontal position of which may be adjusted by
one or two set screws F, or by means of wedges or other suitable contrivance.
G is a plate whereby the bracket is bolted to the machine, or as already stated this
bracket may form part of the machine casting.
The action of my improved compensating contrivance is obvious.
As, in the ordinary course of use, the finger bar is forced out of its true angular
position the hinge shoe can be adjusted by means of the set screw acting on the
shank of the metal cap, and thus the finger bar maintained in its true position.
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 :-
First. In combination with a reaping or mowing machine the compensating
contrivance consisting of a cap A provided with a shank E engaging in a horizontal
slot D and operated horizontally by set screw F or other suitable means for the
purpose and in the manner substantially as herein specified and illustrated in the
Accompanying Drawings.
Second. In reaping and mowing machines, the method of adjusting the angular
position of the finger bar by operating on the Hinge Shoe through the means of a
horizontal slot substantially as herein described and illustrated in the Accompanying
Drawings.
