PROVISIONAL SPECIFICATION.
Improvements in Lawn Clippers or Mowing Machines.
I, WILLIAM BURROWS, of 47 Whitehouse Terrace, Hunslet, in the City of
Leeds, Engineer and Draughtsman, do hereby declare the nature of this invention,
to be as follows:-
According to my improvements the frame sides, sole plate, and a special bearing
as hereinafter referred to, are made or combined in one casting.
The driving roller is journaled in brackets upon the said side frames, and has on
its shaft a bevel wheel which gears with and drives a pinion carried on one end of
a spindle revolving within the aforesaid bearing. At the other end of the spindle
is a disc or crank plate provided with a crank pin which engages in the slot of a
bracket fixed on the cutter plate. The cutter plate derives its motion from the
said disc, or crank plate.
The fingers of the cutter plate slide through and cut the grass against the fixed
fingers. On the driving of the said spindle by the gearing aforesaid motion is
imparted to the cutter plate which gives the required cutting action.
The driving roller may be provided with a pawl catch for throwing the machine
out of gear, so that the machine can be run or drawn backwards, without operating
the cutters.

Improvements in Lawn Clippers or Mowing Machines.
I, WILLIAM BURROWS, of 47, Whitehouse Terrace, Hunslet, in the City of
Leeds, Engineer and Draughtsman, 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:-
My invention has reference to improvements in lawn clippers or mowing
machines.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a side elevation of lawn clipper or mower according to my invention.
Fig. 2, is a plan, and
Fig. 3, is an end elevation of Fig. 1.
Fig. 4, is an elevation of pawl catch, upon driving roller, as hereinafter
referred to.
Fig. 5, is a side elevation partially in section of Fig. 4.
Fig. 6, is a side elevation of modification of means for imparting motion to the
cutter-plate.
Fig. 7, is a front elevation of same.

page_text: According to my improvements the frame sides A, sole plate B, and a special
bearing C as hereinafter referred to are made or combined in one casting.
The driving roller D is journaled in brackets E upon the said side frames A,
and bas on its shaft F a bevel wheel G which gears with and drives a pinion H
carried on one end of a spindle J revolving within the aforesaid bearing C. At the
other end of the spindle J is a disc or crank-plate K provided with a crank-pin L
which engages in the slot M of a bracket N fixed on the cutter-plate O. The
cutter-plate derives its motion from the said disc or crank-plate K.
The fingers P of the cutter-plate O slide on or through and cut the grass against
the fixed fingers or bottom plate R.
On the driving of the said spindle J by the gearing aforesaid, motion is
imparted to the cutter-plate O which gives the required cutting action.
The driving roller D may be provided with a pawl catch S arrangement which
is as ordinary, see Figs. 4 and 5, for throwing the machine out of gear, so that the
machine can be run or drawn backwards without operating the cutters.
arrangement is well known and forms no part of my invention.
This
Figs. 6 and 7. In this modification of means for imparting motion to the cutter-
plate O, a plate T shaped as shown in Fig. 7, and provided with a flanged, recessed,
or dished out part U is pivotted to the bracket V at its top end, and is free to be
moved to and fro at its lower end which is joined or connected by a pin X to the
cutter plate O.
A cam or tappet W, carried on the end of the spindle J, is adapted to engage or
fit in the part U and give (through its shape) by working against the flange,
curved, or raised part U four separate movements or oscillations to the plate T at
its lower end, which being connected or joined to the cutter-plate O by the pin X
imparts corresponding movements or to and fro motions to the cutter-plate O, so
causing the fingers or cutters P to give four separate cutting actions in one
revolution of the spindle J.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. A lawn clipper or mowing machine having the frame sides A, sole plate B,
and a bearing C made or combined in one casting, with a spindle J capable of
revolving within the bearing C for imparting motion to the cutter plate O,
substantially as shown and described.
2. In a lawn clipper or mowing machine, the combination of a bearing C having
a spindle J with a disc or crank-plate K at one end, provided with a crank-pin L
for engaging into a slot M in a bracket N fixed on the cutter-plate O, and a
pinion H at the other end which gears with a bevel wheel G upon the shaft F of
the driving roller D, substantially as and for the purposes shown and described.
3. In a lawn clipper or mowing machine, the combination of a bearing Chaving
a spindle J with a cam or tappet W and a plate T (pivotted to a bracket V)
having a flanged, recessed, or dished out part U, into which the said cam or
tappet W is adapted to engage, the said plate T being connected to the cutter-
plate O, in the manner and for the purposes substantially as shown and described.
