Improved Apparatus for Trimming the Sides of Roads.
ALEXANDER HOGG, Twenty-four, Academy Street, Elgin, N.B., County Road
Surveyor for the County of Elgin, do hereby declare the nature of this invention
to be as follows:-
A process of paring, dressing and reshaping the edges of public and private
roads, being a combination, in a machine, of paring and shaving tools for the
purpose of paring and scarifying the unmacadamised edges of said roads by steam
power or other than animal power. The machine consists of (a) an iron frame
having two carrying wheels; (b) a yoking arrangement fixed to a traction engine
or steam roller, whereby the side road wheel of said engine or engines is adapted
to act as the leading wheel of the contrivance, and whereby the contrivance is
hauled and kept in working position; (c) a regulating lever and spring fixed to
the yoking arrangement whereby the contrivance is lowered or raised; (d) an
adjustable paring wheel fixed to the fore part of the said iron frame; (e) an
adjustable shear or shaving tool, fixed to the said iron frame behind the cutting
wheel "()," shaped and set to push the loosened materials toward the centre of
the road; (f) a scarifying shear with projecting shaving-tusk at rear of the con-
trivance, regulated by lever and spring, shaped and set to push the loosened
materials in an opposite direction from that of the shear "(e)," and finally to
leave them in a continuous heap along the edge of the public road; (g) another
scarifying shear near front of machine at opposite side from "(c)" regulated by
a lever for shaving additional width if necessary, and for guiding any loosened
materials into the front of "(f)," or (h) a shield which may be used at will instead
of "(g)" for preventing the escape of, and for guiding loosened materials into
the front of "(f).”
I claim the above described combination of parts for the particular purpose
set forth, and also the system of yoking attachments "(b)" and "(c)," with the
exception of a boss fixed by bolts to the centre of the road-wheel of engine (which
is supplied by the makers of engines).

Improved Apparatus for Trimming the Sides of Roads.
I, ALEXANDER HOGG, 24, Academy Street, Elgin, County Road Surveyor for the
County of Elgin, do hereby declare the nature of this invention, and in what
Price S/1

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to an improved apparatus for trimming and dressing the
edges of roads, propelled by traction engine power.
The construction and yoking of this apparatus is illustrated in the accompany-
ing drawings in which
Fig. 1 is an elevation and
Fig. 2 a plan of the apparatus showing as much of the locomotive or engine
as illustrates the attachment, less parts hereinafter described.
Fig. 3 is an elevation and
Fig. 4 a horizontal section on the line X Y, to an enlarged scale, of the
shear Figs. 1 and 2.
Figs. 5 and 6 are similar views of the shear m Figs. 1 and 2.
Referring to the said drawings, the apparatus consists of an iron frame a carried
at the rear by two wheels ce¹ which run on the road; the wheel e¹ being less in
diameter than the wheel c in order to allow for the contour or camber of the
road edge. The said wheels are carried on the axle c² the wheel e being keyed
to the axle outside the frame a, while the wheel a runs loosely on the axle inside
the frame. The axle is held in bush blocks which are adjustable as regards
height by a regulating key pin c³.
The apparatus is yoked or attached to the engine as follows:-To the rear
portion of the engine, marked B on the drawings, are two angle lugs 66 rivetted
or otherwise permanently attached to the side 63 of the tender at rear of road
wheel of engine opposite the top of the frame and having a hole for pin and
cotter. Two similar lugs are rivetted to the front of fire box at front of road
wheel not shewn on the drawings. Between the lugs b6 is fixed by pin and cotter
an iron bar which passes round the outside of road wheel and is similarly
secured between the lugs formerly mentioned as being fixed in front of road
wheel. From the front outside angle of the bar 67 is rivetted another lug between
which and the front of the engine is a strong tension rod fixed just under the
smoke box for the purpose of taking up the traction strain. It is not shewn on
the drawings and is adjustable as to proper tightness by an ordinary screw and
nut. On to the bar 67 under the removable boss b, fixed to the centre of engine
road wheel, is rivetted a strong forging, provided with a ring bush bearing to
fit the journal of the boss, and held in position by a cap fixed to end of boss.
to the front of b is securely rivetted at top and bottom a strong bar 6 leaving
sufficient space between it and the foregoing to allow connection of the apparatus,
and give ample play both lateral and vertical. The apparatus is attached to the
bar by two iron plates securely fixed to the frame «, being arranged between
them. The attachment is secured by the insertion of a friction roller, pin and
cotter 10 in front. This completes the connection necessary to transmit the trac-
tion of the engine to the apparatus.
(n
The apparatus is held in a relative position to the engine by a triangular iron
bar d fixed with a stout hinged connection to the frame and to the ordinary
coupling at rear of engine. The apparatus is raised or lowered by a levere
the fulcrum of which is fixed into the iron bar f which is rivetted to the bar 67
and shaped as shewn in Figure 1. The bar f is further secured by a screw stud
to the top of the ring bush 8. The notched regulating quadrant g is also fixed
to the bar f. The attachment between the point of the levere and front part of
the frame is effected by a connection into which is introduced a spring h
Figures 1 & 2, which allows the apparatus to rise over any dangerous obstruc-
tions. This completes the whole connection between engine and apparatus for
traction, holding in position, for carrying, raising or lowering, and generally
regulating the apparatus. It will be observed that the main road wheel of engine
is thereby in effect adopted as leading wheel of the apparatus, and that by com-
pressing the spring by the lever e so much of the weight of the engine, as may

page_text: It is
in certain cases be necessary for the working of the apparatus is (in addition to
the weight of the apparatus itself) transmitted by this means to the cutting tools.
The cutting tools are hereby described separately. The apparatus pares the
edge of roads by the paring wheel & the whole circumference of which is sharpened.
It is of circular form and the blade is fitted to an iron boss, by countersunk
bolts, or the like on which duplicates can be quickly and easily fixed. A stout
axle-spindle is screwed into the boss. The cutting wheel is held in position on
the frame by a U shaped shank made of iron of a square or other shape in
section, a portion of the thickness of which is let into the frame 'a.
regulated and secured to the frame by two tightening shackles. The inner end
of the axle is similarly secured to the part a² of frame. The axle revolves in a
tube-bush which is renewable; the whole being strong and rigid to withstand
shock or pressure.
The wheel is set to pare the edge with a slight slope towards
the road as shewn more particularly in Fig. 2, and is used along with the shear m
and point m (hereinafter described) when the apparatus is trimming a side with
an upright border; but, together with the said point, is removed when the pro-
jecting point shear m*, hereinafter described is in use trimming a side opposite
a ditch.
Immediately behind the paring wheel is the cutting shear m mounted on a
strong iron or steel stock m¹ which stock is securely fixed to the frame a with
screw bolts as shewn on Figure 1 and with an adjustable screw bolt inserted
through the web m³ and the cross bar a³ Figure 2. The cutting portion of the
shear is set to its work at an angle of about 30 degrees and is fixed in a checked
bearing to the lower edge of the upper plate to admit of renewals. The point m²
of the shear m used along with the paring wheel at an upright border being
subject to considerable tear and wear is made of hard chilled cast iron; it is held
in position by a socket at the lower front part of the stock m¹ and secured by a
bolt.
The projecting point shear m used for trimming sides opposite ditches has an
upper plate m on which the cutting part mt is fixed on a checked bearing for
renewals. It is fixed as an extension (forward) of the shear m by first removing
the wheel from its bush and the point m² from its socket, and is attached to
the front end of the shear m by bolts. This projecting shear is stayed in front
by two tie rods m² joined together near the shear at the back of which they are
bolted, the other ends being secured, one to the nearest point of the frame a the
other to the nearest point of the frame u².
A little to the front of the shear m and nearer to the locomotive is another
cutting shear n mounted on a stock n¹ similar to that of the shear m and bolted
to the underside of the portion 2 of the frame; the upper plate of this shear is
shorter than m. The cutting part of the shear is bolted to the lower edge of the
front plate and projected in a tusk somewhat flattened at the heel end in order
to allow it to pass under loosened materials removed by the front part. This
shear is stiffened and regulated transversely by a shank n³ which is inserted into
a socket in the stock n and passed up through a slot in the plate n. The
point n is exactly the same in quality and shape and is fixed in the same manner
as that described for the shear m. The said shears m and n are shewn to a
larger scale and removed from the apparatus, in Figs. 3 to 6. The cutting
points man while cutting through or pushing aside all ordinary obstructions will
break and thereby give warning should they meet with any hidden obstruction,
the effects of which might damage other parts of the apparatus.
Toward the rear of the apparatus is the raking shear o
deeper upper plate than the other two. As shewn on Figure 1 the cutting
part ol is bolted to a checked bearing on the lower edge of the upper plate for
convenient renewals. At the rear end this cutter is extended as a projecting
tusk flattened at the heel to facilitate its passage underneath materials loosened
in front. This shear is drawn along by two drag bars p and p² diagonally braced,
This shear has a

page_text: hooked on with hinged joints to the cross bar a³. In addition to regulation as
to depth of cut by the raising or lowering of the apparatus by the lever e this
shear is separately regulated as to pressure and depth of cut by the lever pa
through the connecting rod p³ and cranks 24 fixed on the axle 25 and acting on
a spring attached to, and seated on a bracket fixed on the drag bar p at the
back of the shear o.
The shield is fixed to the frame a for the purpose of preventing the escape
of material loosened by the shears m and n beyond the range of the raking
shear o.
The working is performed after construction and attachment of the apparatus,
as follows:
The apparatus being transported to the road edge to be operated on view sights
are provided to guide the engine driver as to line, one connected on front of
engine, and one fixed just in front of the driver; both sights are parallel with
the centre line of engine. One workman stands on a platform fixed at the top
of the apparatus (a portion of which is shewn at s on Figure 2) to operate the
regulating handles. At the front of the apparatus is the scratching tool n5 cutting
about an inch deep to roughly separate the parts to be cleaned by the respective
shears m and n. For sides with upright borders the shear cleans off the thinner
portion to 8 inches or thereby distant from the border, whilst the cutting wheel k
pares off to the distance required. m, the shear behind the cutting wheel k, cuts
away the portion next the border; the shield prevents the escape of loosened
materials, guiding them in front of the raking shear o; which shear cleans off any
inequality or vegetation beyond the ranges of the shears m & n and pushes all
loosened materials to near the edge of road where it is ready to be thrown off
or carted away. The shears are fixed on the frame so as to slightly overlap each
other, and at such heights as leaves the side-road with a fall towards the edge or
ditch as the case may be.
For sides opposite ditches the projecting shear m* slightly overlapping the
ditches cuts away irregularities and vegetation on the surface beyond the reach
of the shear m.
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: —
1. An apparatus for paring and dressing the edges of roads, adapted to be
worked by engines known as traction engines or steam rollers whereby the said
road edges formerly pared and dressed by manual labour or other means can be
pared and dressed expeditiously by one operation, thereby sccuring superiority
of work and a saving of labour and expenditure.
2. The construction, arrangement and mode of attaching the frame of the
apparatus for trimming and dressing the sides of roads, to a traction or other
locomotive, substantially as and for the purpose herein before described and shewn
in the accompanying drawings.
3. The general arrangement, construction and combination of the circular paring
knife with the cutting shears m, n and raking shear o; and the means whereby
the requisite pressure is given to the frame carrying the foregoing tools, from
the propelling engine, substantially as herein before described and shewn in the
accompanying drawings.
4. In apparatus for trimming and dressing the sides of roads the cutting
points man of the two front shears m. & n and their mode of fixing, which
while cutting through or pushing aside all ordinary obstructions will break and
thereby give warning should they meet with any hidden obstruction the effects
of which might damage other parts of the apparatus, substantially as herein-
before described and shown in the accompanying drawings.
5. In apparatus for trimming and dressing the edges of roads, the inter-

page_text: changeable arrangement of the cutting wheel k and point m² for upright border
along with the projecting point shear m for borders opposite ditches, all sub-
stantially as hereinbefore described and shewn in the accompanying drawings.
