PROVISIONAL SPECIFICATION.
Improvement in Machines for Cutting Turf.
JOSEPH DALGARNO, Damside Cottage Gilcomston, Aberdeen, Gardener, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of a machine for
cutting turf into squares or slabs preparatory to raising said squares or slabs of
turf for laying out bowling & tennis greens & such like. An ordinary cutting
disc is used of suitable diameter which is fixed in a shears to which is attached
the handle by which the operator pushes it along in front of him. Another part
preferably of cast iron and partaking of the form of a shears or fork is attached to
the shears holding the disc so that the latter shears falls between the legs of the
outer shears which is made with the space sufficient between the legs to allow of
one small wheel to revolve freely on its axis on cach side of the disc. The axis of
these wheels are attached to the outer shears on the lower side and in such a .
position that the disc between them extends beyond them the distance required for
the depth of the cut. This casting bearing the wheels is adjustable on the inner
shears holding the disc so that the depth required for the disc to cut can be adjusted
from 1 to 3 inches.
The novelty of this invention consists in the addition of these guide wheels to
the disc without which it is not workable & by means of which it is an implement
fitted for the purpose to which it is applied.

COMPLETE SPECIFICATION.
Improvement in Machines for Cutting Turf.
I, JOSEPH DALGARNO of Damside Cottage, Gilcomston, Aberdeen, North
Britain, Gardener, 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 :—
more
This invention which relates to improvement in machines for cutting turf has for
its object to provide a machine which will cut the turf into squares or slabs for use
in laying out bowling, croquet, tennis and other such like greens, in a
efficient manner than hitherto; the said machine owing to its construction may be
set to cut the turf to any desired depth.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe the same with reference to the annexed
explanatory drawings.
Figure 1 is a plan and Figure 2 a side elevation of my improved turf cutting
machine.
Referring to the said drawings, I employ an ordinary steel or other cutting
disc A, which revolves on its axle a; the said axle a being carried in the lower
ends of the shears or fork B, to the upper end of which the handle C is attached,
the said handle C being somewhat after the shape of a lawn mower handle, and
made of sufficient length as to enable the operator to work the machine by pushing
it along in front. In order to maintain the cutting disc A in any desired position
so as to give a uniform depth of cut as well as to retain the said disc in an
upright position I mount a guide wheel or roller D on each side of the said disc A,
the said wheels D being capable of freely revolving on their axes d which are
Din 1

page_text: suitably connected to and carried by an adjustable cast iron or other bracket E
shaped after the form of a fork or shears as shown, and adjustably mounted on the
shank of the main fork or shears B where it is provided with a suitable hand
pinching or binding screw F, so as to enable the operator to set the cutter disc A
to project past the guide wheels D according to the depth of cut desired. The
said bracket E is formed with two or more weights G, or otherwise made of
sufficient weight as to cause the disc A to cut the grass or turf freely.
The whole thus forming a turf cutting machine which only requires to have its
cutting disc A set to the depth of cut desired and then propelled forward by the
operator through the medium of the handle C which is greatly assisted by the
guide wheels D, travelling along the ground and so steadying and preventing
the disc A. from penetrating the turf beyond the required depth.
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
1st. In turf cutting machines, the employment of guide wheels or rollers D,
substantially as, and for the purposes hereinbefore described and shown in the
accompanying drawings.
2nd. In turf cutting machines, the means whereby the guide wheels or rollers
may be set so as to regulate the depth of the cut substantially as described and
shown in the drawings.
3rd. In turf cutting machines, the arrangement and construction of the bracket
or fork E and weights G, substantially as described and shown in the drawings.
