page_text: JAMES STAFFORD, Gentleman, Rutland Hall, Crumlin, Co. Dublin, do. hereby
declare the nature of this invention to be as follows:-
**
Instead of the revolving cutter commonly used at present, I propose to use a
cutter somewhat similar to the horse clipper" only moved by wheels and levers
to suit.
This I believe to be a decided improvement and the adaptation to this purpose
novel.
I, JAMES STAFFORD, of Rutland Hall, Crumlin, County Dublin, Ireland, Gentle-
man, 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 relates to a new or improved lawn mower or machine for cutting
grass and the like.
By this invention a frame similar to that generally used for lawn mowers is
adopted.
The cutting blades are formed by two plates of steel or other suitable material
placed one above the other as in hair clippers between or in front of supporting
runners or wheels, the said plates having cutting teeth on their front edges.
The upper blade is reciprocated or vibrated by means of a wheel carrying an
eccentrically placed pin and actuated by gearing connecting it with one or both
supporting runners or wheels, so that when the supporting wheel revolves, it gives
a cross or sawing motion to the upper plate, which causes its teeth to intersect
those of lower plate, by which means as the machine is propelled forward the
blades of grass or other material to be mown or cut are nipped between the teeth
of the two plates or blades and thus cut.
Ball or other bearings may be used in all suitable parts.
In order that this invention may be better understood reference may be made
to the accompanying drawings in Fig. 1 of which a side view of the improved lawn
mower is diagrammatically shown. Fig. 2 is a front elevation and Fig. 3 a plan
also showing the invention somewhat diagrammatically, that is to say without
Pi Q77

page_text: particular illustration of details of construction which may be varied without
departing from the spirit of this invention.
A is a frame. B a fixed cross bar serving as an axle to the two running
wheels C, C, and as a support to the adjustably attached arms DD of the lower
blade E. FF are two wheels for supporting the front part of the frame. G is
the upper blade which is moved to and fro on the guiding pins H H by the excen-
trically placed pin J on the bevelled wheel K which is revolved by the be elled
wheel L on the side of one of the running wheels C. The pin Jengages in a flanged
slot M in the upper blade G.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:-
11
In a machine for cutting or mowing grass and the like the combination of two
plates or blades having teeth on their front edges, placed one above the other, ona
of said plates being given a suitable reciprocating or sliding movement on the other
by means of a wheel carrying an eccentrically placed pin and operated by suitable
gear from the supporting wheel or wheels of the machine, substantially as described.
