I, PHILIP PIERCE of Mill Road Iron Works, Wexford, Ireland, Engineer do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to more effectually than heretofore clear the track or
cleared space made by the track clearer of a mowing machine between the cut and
uncut crop.
In mowing machines as heretofore constructed, when cutting heavy or tangled
meadows the cut crop is liable to accumulate between the end of the track clearer
handle and the finger bar. I have found that if the track clearer is lifted at its outer
end this accumulation will be relieved; the space between the lower end of the handle
and the ground being increased, the handle slides over the accumulated crop and
leaves it behind. According to my invention I automatically cause the track clearer,
or it may be some portion thereof to rise and fall. A convenient way of effecting this
motion in the track clearer automatically is by pivotting to the track clearer a wheel
rolling on the ground the axis of which is eccentric to its periphery. The track
clearer is secured to the shoe by bolt on which it also pivots. I fix to the track clearer
a stud or axle or other appliance which will act as an axis for the roller to revolve upon;
the point in the roller about which it revolves is not its centre but is placed at some
part of the roller nearer to the circumference than the centre. As the shoe moves
forward carrying with it the track clearer, the roller will revolve and roll upon the
ground but as the point about which it revolves is out of the centre of the wheel or
roller the said roller will cause an undulating motion to be communicated to the track
clearer which will thus be caused to vibrate on the pivot or bolt. The outer end of the
track clearer will by this means rise and fall and with it the track clearer handle
allowing the latter to pass over the accumulating crop.
Other appliances may suggest themselves by which the vibrating action of the track
clearer may be obtained without departing from my invention but I find the eccentric
roller as herein described to answer well.

page_text: I, PHILIP PIERCE of Mill Road Iron Works, Wexford, Ireland, Engineer 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 object of this invention is to more effectually than heretofore clear the track or
cleared space made by the track clearer of a mowing machine between the cut and
uncut crop.
In mowing machines as heretofore constructed, when cutting heavy or tangled
meadows, the cut crop is liable to accumulate between the end of the track clearer
handle and the finger bar. I have found that if the track clearer is lifted at its outer
end this accumulation will be relieved, the space between the lower end of the handle
and the ground being increased the handle slides over the accumulated crop and leaves
it behind.
According to my invention I automatically cause the track clearer, or it may be
some portion thereof, to rise and fall. A convenient way of effecting this motion in
the track clearer automatically, is by pivotting to the track clearer a wheel, rolling on
the ground, the axis of which is eccentric to its periphery, and the invention will be
clearly understood by reference to the accompanying drawings.
Figure 1 shews in plan the outer end of a finger bar and shoeA constructed according
to my invention; Figures 2 and 3 are side elevations of similar parts shewing the
track clearer in the lower and raised position.
The track clearer C is secured to the shoe A by the bolt B on which it also pivots.
D is the track clearer handle which assists in forming the swath.
I fix to the track clearer a stud or axle or other appliance which will act as an axis
for the roller G to revolve upon; the point in the roller G about which it revolves is
not its centre but is placed at some part of the roller nearer to the circumference than
the centre as seen in Figures 2 and 3.
It will be seen that as the shoe A moves forward carrying with it the track clearer C,
the roller G will revolve and roll upon the ground but as the point about which it
revolves is out of the centre of the wheel or roller the said roller G will cause an
undulating motion to be communicated to the track clearer C which will thus be caused
to vibrate on the pivot or bolt B, the outer end of the track clearer will by this means
rise and fall and with it the track clearer handle D allowing the latter to pass over the
accumulating crop.
Other appliances may suggest themselves by which the vibrating action of the
track clearer may be obtained without departing from my invention but I find the
eccentric roller as herein described to answer well as being not liable to choking and
derangement.

page_text: 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 a mowing machine, causing the track clearer or any portion thereof to rise and
fall automatically substantially as and for the purpose hereinbefore described with
reference to the accompanying drawings.
2. In mowing machines, the particular means described, consisting of the roller G
for causing an undulating motion to be communicated to the track clearer C
substantially as and for the purposes hereinbefore described with reference to the
accompanying drawings.
