PROVISIONAL SPECIFICATION.
An Apparatus for Cutting or Clipping the Grass on the Edges
of Grass Lawns or Borders.
WILLIAM REID, Seedsman, 8 Hadden Street, Aberdeen ALEXANDER SIMPSON,
Blacksmith, Wellington Road, Aberdeen do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in machines for cutting the overhanging
grass on lawn edges, round flower plots & such like.
The machine consists of a wheel or roller & disc both fitted tightly on the
same shaft, (said shaft runs in bearings in a fork to which the propelling handle
is attached) and of an under blade or fixed knife & a series of blades which act
upon it.
The disc is preferably of the same diameter as the wheel & is fitted at the
distance of one or more inches from it.
The machine is carried on the wheel or roller which is moved by the operator
along the top of the verge thereby imparting a revolving motion to the disc.
The cutting mechanism consists of an under blade or knife & a series of blades
acting on it as before mentioned.
The under blade is attached by bolts or other convenient manner & so shaped
that it passes underneath the grass to be cut much in the same way as the lower
blade of a verge shears. The series of blades which act on the fixed knife are
attached in an adjustable manner to one side of the disc & occupy the whole space
of that side, their cutting edges projecting beyond the periphery of the disc. (The
number of knives are preferably 6 but a greater number could be used.)
An important part of the novelty consists in the manner in which these blades
act on the lower blade. Their cutting edges are curved, the curved edge com-
mencing at one side of the knife close to the periphery of the disc & extending to
the other side of the knife which projects inches or more beyond the periphery.
By this arrangement cach knife as it comes round passes the lower knife with a
combined clipping & sawing motion, & the adjustable manner referred to above in
which these knives are attached to the disc, allows of their being so set that while
passing the edge of the lower knife a clean cut can always be secured.

An Apparatus for Cutting or Clipping the Grass on the Edges
of Grass Lawns or Borders.
ALEXANDER
We, WILLIAM REID, of 8, Hadden Street, Seedsman, and
SIMPSON, of Wellington Road, Blacksmith, both in Aberdeen, in the County of
Aberdeen, 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 machines for cutting the grass overhanging the edges
or verges of lawns or borders and it comprises the improvements hereinafter
described.
In carrying out the said invention we provide a suitable frame to which the
handle for pushing the apparatus is connected and in which is mounted a shaft

page_text: having fixed to it a travelling wheel having a curved periphery. At the outer
end of this shaft is fixed a disc to which is attached a series of blades or cutters
having curved cutting edges, which cutters operate in conjunction with a blade or
knife fixed to the frame and adapted to slide against the edge to be trimmed.
To enable the said invention to be fully understood we will describe the same by
reference to the accompanying drawings in which :-
Figure 1 is a front elevation of our improved machine with the handle removed,
and,
Figure 2 is a side elevation of the same.
Figure 3 is a side view of the framing with the fixed blade attached, and,
Figure 4 is a sectional plan of the framing with the travelling wheel and cutter-
disc.
Figures 5 and 6 are elevations from opposite sides of a portion of the cutter-disc
and one of the cutters, and,
Figure 7 is a vertical section of the same.
a is the framing of the machine having the flanged arm to which the handle is
pivoted at c and provided with a slot d for enabling the angle of the handle
relatively with the frame to be adjusted.
ee are bearings in the said frame in which the shaft is carried and g is the
travelling wheel with the curved periphery secured to the said shaft. is the
cutter-disc also secured to the shaft, and ii are the blades or cutters each
of which as shown in Figures 2 and 6 are fixed to the said disc by a bolt A.
Each blade has also arranged in conjunction with it two set screws k k for adjusting
it laterally.
is the fixed knife secured to an arm on the underside of the framing as shown
most clearly in Figure 3 and adapted to have the cutters i i work in conjunction
with it in a manner which will be readily understood.
The edges of the cutters ii are convex and the cutting edge of the fixed blade
is concave in order that as the cutters ii are rotated with the disc they will exert a
combined clipping and shearing action whereby a clean cut is obtained. The
travelling wheel is provided with a curved periphery in order that the implement
may be inclined to suit the angle of the edge being cut.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :―
1. In an apparatus for cutting or clipping the edges of grass lawns or borders,
the combination of a fixed blade and a disc carrying a series of detachable blades
the said blades having curved cutting edges, substantially as described.
2. In an apparatus for cutting or clipping the edges of grass lawns or borders the
combination of a rotating cutter and a fixed cutter of the kind described and a
travelling or driving wheel having a curved periphery, substantially as and for the
purpose set forth.
3. The manufacture and use of the improved apparatus for cutting or clipping
the edges of grass lawns or borders, substantially as hereinbefore described and
illustrated in the accompanying drawings.
