Improvements in and relating to Roadside Paring Machines.
We, ALEXANDER MACDONALD and JAMES MACDONALD, of the Firm of Macdonald
Brothers, of Portsoy, in the County of Banff, Engineers, do hereby declare the
nature of our invention to be as follows:-
This invention has reference to and comprises improvements in and relating
to road side paring machines and consists of a new or improved construction
or arrangement and combination of the parts of machines for paring the sides
of roads, or footpaths of roads, which has hitherto been usually done by hand
labour, and which improvements will enable such work to be done with accuracy
and economy.
In carrying into practice the improvements of this invention the frame or main
body of the machine is mounted on three wheels two in front and one in rear,
the latter being mounted on a vertical rod to swivel in the frame as the guiding
wheel, a hand lever being secured to the upper part of the vertical rod. A'
horizontal shovel shaped plate is attached to the machine frame and is formed
with a tusk, or vertically projecting part to act as a vertically cutting edge. This
shovel plate is carried at such a distance below the frame as to cut off the turf
to the desired depth and leave a perfectly level surface on the road side. A steel
board is fitted above the shovel plate similar to a plough board to throw the
cut turf to one side as the machine proceeds.
The two front wheels are not mounted on an axle but are independently and
interchangably carried on studs at the lower end of levers, which are carried by
eyes on a square bar to which they are adjustably secured by pinching screws.
This square bar is carried in a hollow sleeve hinged or jointed to the front of
machine frame. The upper part of one of the wheel levers pierced with holes
for adjustably connecting one end of a connecting rod, the other end of which is
jointed to a lever at rear of machine frame fitted with a quadrant and spring
catch or pawl. By this means the upper end of the wheel lever can be shifted
from an angled to a vertical position and so adjust the height of machine frame
and cutting shovel plate.
A small guide wheel is adjustably suspended from the machine frame between
the two front wheels. The whole is designed to be drawn by horse power.

Improvements in and relating to Roadside Paring Machines.
We. ALEXANDER MACDONALD and JAMES MACDONALD, of the Firm of Macdonald
Brothers, of Portsoy, in the County of Banff, Engineers, do hereby declare the
[Price 8d.1

page_text: nature, of our invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement in
-writing, reference being made to the accompanying drawings:-
This invention has reference to and comprises improvements in and relating
to roadside paring machines and consists of a new or improved construction
or arrangement and combination of the parts of machines for paring the sides
of roads, or footpaths of roads, which has hitherto been usually done by hand
labour, and which improvements will enable such work to be done with accuracy
'and economy.
And in order that our said invention may be properly understood we have
hereunto appended one sheet of explanatory drawings in which Figure 1 is a
sectional elevation of the machine and Figure 2 a plan of same, while Figure 3
illustrates the construction of the paring appliance.
In carrying into practice the improvements of this invention the frame A or
main body of the machine is mounted on three wheels, two, B, C in front and
one D. in rear,
the latter being mounted on a vertical rod 1) to swivel in the frame
as the guiding wheel, a hand lever. De being secured to the upper part of the
vertical rod, a rack being fitted between the handles E-to-hold it in any
desired position. A horizontal shovel shaped plate F is attached to the machine
frame A and is formed with a tusk F, or vertically projecting part, to act as a
vertically cutting edge. This shovel plate F is carried at such a distance below
the frame as to cut off the turf to the-desired-depth-and-leave_a_perfectly_level
surface on the roadside. A steel board G is fitted above the shovel plate 1
. similar to a plough board to throw the cut turf to one side as the machine proceeds.
The two front wheels B, C, are not mounted on an axle but are independently
and interchangeably carried on studs H at the lower end of levers H, which
are carried by eyes H2 on the square ends of a bar I to which they are adjustably
secured by pinching, screws. This square bar I is carried in a hollow sleeve J
which may be hinged or jointed to the front of machine frame, or as shown in
the drawings the sleeve may be secured to the machine frame and the part of the
bar passing through same may be round to oscillate within it. The upper part
of one of the wheel levers is pierced with holes for adjustably connecting one
end of a connecting rod K, the other end of which is jointed to a lever L at rear
of machine frame fitted with a quadrant M and spring catch or pawl N. By
this means the upper end of the wheel lever H can be shifted from an angled to
a vertical position and so adjust the height of machine frame A and cutting shovel
plato F.
A small guide wheel is adjustably suspended from the machine frame by
the rod O between the two front wheels B, C; and may be secured at the desired
height by the pinching screw (2. The whole is designed to be drawn by horse
power.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
First. Road side paring machines constructed and arranged substantially as
herein described and illustrated by the accompanying drawings.
Second. The construction or general arrangement and combination of the parts
of machines for paring the sides of roads, or footpaths of roads, substantially as
herein described and illustrated by the accompanying drawings.
Third. In road side paring machines the construction and arrangenient of the
paring shovel F and tusk I, substantially as herein described and illustrated
by the accompanying drawings.
Fourth. In road side paring machines the fitting of the front wheels inter-
changeably and independently adjustable in combination with the actuating
lever L and rod K, substantially as herein described and illustrated by Figures 1
and 2 of the accompanying drawings.

page_text: Fifth. In road side paring machines the construction or arrangement and
combination of the hind steering wheel D with its rod D', lever D³, and rack D³,
substantially as herein described and illustrated by the accompanying drawings.
