IMPROVEMENTS IN THE CONSTRUCTION OF MOWING AND REAPING MACHINES
Year: 1885

page_text: I, PHILIP PIERCE of Mill Road Iron Works Wexford Ireland Engineer do hereby
declare the nature of said Invention for "IMPROVEMENTS IN THE CONSTRUCTION
OF MOWING AND REAPING MACHINES" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
My Invention relates to improvements in Mowing and Reaping machines in
which the main shoe is connected to the framing through the medium of an
angular extension, the front side of which is a radius bar having its lower or outer
end hinged to the main shoe and its upper or inner end hinged in like manner to
the framing, the second side of such angular extension being a stay extending from
the lower end of the radius bar to any convenient rear part of the framing to
which it is also hinged. My improvements consist chiefly in the combination with
such angular extension of a front brace bar hinged at its lower end to the main
shoe and at its upper end to a prolongation of the framing in or nearly in line
with the axis of the pins on which the radius bar and stay are hinged.
In order that my invention may be fully understood I will describe the same
with reference to the accompanying drawings.
Figure 1 shows in sectional elevation such portions of a mowing machine as are
necessary to illustrate my invention and the manner in which I carry my Invention
into effect Figure 2 is a part plan of the same. A A A A is the framing which
is supported by and in which the main axle B B revolves (and which may carry a
gearing of either the open or enclosed type) which framing I prefer to cast in one
piece with the pole sockets C C. The limb A³ A is of a U shaped section into
which is fitted a barrel in which a shaft revolves-this shaft has fitted on one end
the pinion D and on the other end the crank plate or disc E the latter imparts a
reciprocating motion to the cutters F by means of the connecting rod G. The
U shaped limb is further extended in front of the crank plate or disc E and is of a
suitable formation to constitute a shield H for the crank plate or disc E. The
main shoe I carries the cutting mechanism and is connected to the framing A¹ A² A³ A*
by means of the radius bar J. K the lower end of which is hinged to the shoe I the
upper end being hinged at A' to the framing A³ A2 A3 A*; rigidity of the radius
bar J, K is produced by the stay L M which extends from the lower end J of the
radius bar J K to any convenient part of the framing A' A² A³ A' as to M where

page_text: it is also hinged or pivotted as shown In the main shoe I a lug N is formed and
at a point O in the shield H which may be in.line with the axis of the hinge pins
at M and A' one end of the front brace bar P P is pivotted the other end being.
hinged to the lug N in the main shoe herein before referred to. The function of
the front brace P P is to assist the joint at J and prevent the sagging backwards
of the outer end of the cutting mechanism.
It is not essential to the success of this invention that the shield H be an
integral part of the framing A1 A2 A3 A4. It may be a separate piece to be fixed
in any approved manner to the framing, but for the purpose of simplifying the
parts I prefer to make it in one piece with the framing.
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
In a mowing machine having a radius bar J K and a stay L M forming
an angular extension jointed or hinged to the framing and to the main shoe I.
The combination with such angular extension of a front brace P hinged at one end
to the said main shoe I and at its other end to a prolongation of the framing all
constructed and acting as and for the purpose herein fully set forth.
