lug 26 having a vertical aperture 27 wherein
is fitted a shank 28 having at its lower end a
laterally offset lug 28 upon which is jour-
naled a sharp edged disk 29 constituting an
5 auxiliary cutter which is intended and adapt-
ed to penetrate slightly into the soil for the
purpose of trimming that portion of the grass
which is not reached by the rotary cutters,
and more particularly for the purpose of
o trimming the roots of the grass at the edge of
the lawn or plot. The cutter carrying shank
28 is held in position adjustably by means of
a set screw 30, and said shank is provided
with a recess or notch 31 through which the
15 edge of the cutter is compelled to pass as will
be best seen in Fig. 5 of the drawings; the
object of this construction being to keep the
.edge of the cutter disk clear' from.clay and
other obstructions which might have a tend-
20 ency to adhere thereto.
The body of the frame A has an aperture
31 wherein is fitted a shank 32 carrying a
caster wheel 33 which is disposed intermedi-
ate of the drive wheel 4 and the cutting appa-
25 ratus, which latter will thus be supported at
the desired elevation above the ground,
which may be regulated by properly adjust-
ing the shank 32; the latter being secured byI
means of a set screw 34.
30 A handle bar 35 whereby the machine may
be conveniently manipulated, is bolted or
otherwise suitably secured upon the casing
plate 7.
From the foregoing description taken in
35 connection with the drawings hereto an-
nexed, the operation and advantages of this
invention will be readily understood.
The machine is light, inexpensive in con-
struction, and it may be very conveniently
40 operated for the purpose of trimming the
edges of lawns, beds and plots which cannot
be conveniently reached by lawn mowing
machines of the ordinary construction.
Having thus fully described the invention,
45 what I claim as new is:
1. In a lawn trimming machine a frame
having a forwardly extending lug, a shaftjournaled transversely in the frame, a drive
wheel supported for rotation by the for-
wardly extending lug and having an internal 50
gear, a pinion upon the end of the transverse
shaft that projects within the drive wheel,
clutch means for connecting said pinion with
the shaft, a hub upon the opposite end of the
shaft having radially extending cutter carry- 55
ing arms, a stem laterally adjustable in the
frame and provided with a head, and a plu-
rality of forwardly divergent fingers upon
said head, said fingers being disposed in an
approximately vertical plane adjacent to the 6o
cutter carrying hub.
2. In a lawn trimming machine, a frame, a
transversely disposed driven cutter carrying
shaft, a transversely adjustable member car-
rying a plurality of divergent fingers disposed 65
in an approximately vertical plane and co-
operating with the cutters carried by the
shaft, an auxiliary rotary sharp edged cutter
disk supported in rear of the fingers and ap-
proximately in the same vertical plane. 70
3. In a lawn trimming machine, a frame
having a forwardly extending lug, a drive
wheel supported for rotation upon said lug, a
shaft journaled transversely in the frame and
extending within the drive wheel, a pinion 75
upon the shaft meshing with an internal gear
upon the drive wheel, clutch mechanism con-
necting the pinion with the shaft, a cutter
carrying hub upon the opposite end of the
shaft adjacent to the frame, a member trans- 8o
versely adjustable upon the frame, a plural-
ity of divergent fingers carried by said mem-
bers and co-operating with the cutter upon
the shaft, a vertically adjustable shank car-
ried by the frame intermediate the connect- 85
ing mechanism and the drive wheel, and a
supporting wheel carried by said shank.
In testimony whereof, I affix my signature
in presence of two witnesses.
