Improvements in and relating to Lawn Mowers.
I, CHRISTOPHER HODSON of 115 Upper Dale Road, Derby in the County of
Derby, Mechanical Engineer, do hereby declare the nature of this invention to be..
as follows:-
1
The object of my invention is to provide a lawn mower at a moderate cost which
will cut grass and the like of any height and in very awkward places such as in
corners, round the roots of trees, along the edges of the lawn and the like, which
cannot always be done with the types of lawn mowers now in use.
In carrying out my invention I arrange a number of knives fixed in a horizontal
or approximately horizontal position on a spindle or frame these knives may either
be set to radiate from a centre or set eccentrically of the centre, they will in any
case be arranged so that when the machine or apparatus is pushed forward they
will be pushed well into the grass; either above or below these fixed knives
I mount on the same spindle a plate consisting of knives or a frame or plate
holding knives, the said plate or frame being free to revolve on the spindle and in
conjunction with the fixed knives so cut the grass or the like, when put into gear
with the driving part of the apparatus as will be hereinafter explained.
The depth of cut may either be varied by adjusting the height of the wheels or
by raising or lowering the fixed knives and revolving cutters in any well known
manner. Motion may be communicated to the revolving cutters either by cord,
band, chain or gearing and driving wheel or wheels, roller or rollers, running on
the ground; or, by a hand wheel as desired.
I
may also
arrange a revolving brush at either side or behind the cutters, to be
driven in any suitable way as above and sweep into a box or the like the grass or
other substance cut.
The apparatus may be propelled in any suitable manner and the cutters may if
desired be arranged to cut the full width of the ground wheels from outside to
outside, but the machine would preferably, in such a case, be provided with side
guards to prevent accidents.

Improvements in and relating to Lawn Mowers.
1, CHRISTOPHER HODSON of 115 Upper Dale Road, Derby in the County of
Derby, Mechanical 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 :-
L
The object of my invention is to provide a lawn mower at a moderate cost
which will cut grass and the like of any height and in very awkward places such
as in corners, round the roots of trees, along the edges of the lawn and the like,
which cannot always be done with the types of lawn mowers now in use.

page_text: In describing my invention reference will be had to the sheet of drawings
forming a part of this specification:-
Figure 1 being a side elevation and Figure 2 a general plan shewing one
adaptation of my invention.
In carrying out my invention I arrange a number of knives or teeth A. fixed in
a horizontal or approximately horizontal position on a spindle B, or frame, these
knives may either be set to radiate from a centre or set eccentrically of the centre,
they will in any case be arranged so that when the machine or apparatus is pushed
forward they will be pushed well into the grass; either above or below these
fixed knives I mount on the same spindle a plate or the like consisting of knives,
or, a frame or plate holding knives C, the said plate or frame being free to revolve
on the spindle B and in conjunction with the fixed knives A so cut the grass or
the like, when put into gear with the driving part of the apparatus as will be
hereinafter explained, the revolving knives or cutters C are shewn upon the
drawing mounted above the fixed knives or teeth A.
The depth of cut may be varied either by adjusting the height of the wheels or
by raising or lowering the fixed knives and revolving cutters in any well known
manner, upon the drawings adjustable wheels D are shewn for this purpose.
Motion may be communicated to the revolving cutters either by cord, band, chain,
or gearing, driving wheel or wheels, roller or rollers, running on the ground; or,
by a hand wheel as desired.
Upon the drawings the knives or cutters C are shewn driven from a roller
shaft E a bevilled wheel F being mounted thereon and driving a pinion G, the
latter being keyed to and driving a shaft H also carrying a bevilled wheel J
which gears with a pinion K mounted loosely on the spindle B, and fixed to the
frame or the like carrying the revolving cutters. In cases where a roller shaft is
not provided and the mower simply runs on two side wheels I may mount a
villed wheel on the shaft upon which the side wheels are fixed, the said bevilled
neel gearing with the pinion connected or fixed directly to the horizontally
revolving blades or cutters. I do not however wish to bind myself to any
particular method of driving the said horizontally revolving cutters.
may also
arrange a revolving brush at either side or behind the cutters, to be
driven in any suitable way as above and sweep into a box or the like the grass or
other substance cut, as is well known in lawn mowers.
The apparatus may be propelled in any suitable manner and the cutters may if.
desired be arranged to cut the full width of the ground wheels from outside to
outside, but the machine would preferably, in such a case, be provided with side
guards to prevent accidents, I do not however wish to claim novelty in the latter
respect.
Each knife, tooth or cutter may be made to take out if desired for convenience
in repairing or sharpening, said knives or cutters being attached to the body by
Imeans of screws, lock nuts or the like. An adjustable tension spring L may be
provided for tightening up the knives or cutters.
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 :-
The improvements in and relating to lawn mowers consisting of horizontally or
approximately horizontally revolving knives or cutters, driven in any well known
manner in conjunction with fixed knives or teeth, and tension adjustment,
substantially as described and illustrated.
