COMPLETE SPECIFICATION.
An Improved Brake for Lorries and other Four-wheeled Road
Vehicles.
I, SAMUEL MCCALL, 1 High Street, Kilmarnock, Ayrshire, Cartwright and
Joiner 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:-
A hardwood bar a is suspended from the dumbjack bolts of springs of lorry or
other vehicle, by two iron stays H hung on dumbjack bolts, having eyes formed on
upper ends to fit dumbjack bolts & also screwed on other ends & having a collar
welded on them, the said iron stays H are put through the said hardwood bar a &
screwed up by nuts on under side of wood bar a.
This hard wood bar a is formed broader in the centre of its length (reaching over
both hind wheels) & tapering to each end is formed round on the ends for some
distance for the reception of a cast iron block b on each end, the said cast iron
block 6 having a round hole same size as end of wood bar a, is slipped on wood
bar a & fastened to bar a by a set screw c, which is tapped into cast iron block b &
which is also screwed into the wood bar a.
In the centre of the hardwood bar a a hole is bored horizontally & an iron
plate d with a hole same size as hole bored in bar a, is screwed on each side
of bar a
An iron rod e, with eye on one end & other end screwed for some distance, is put
through the said hole in wood bar a & is fixed in it by a nut on each side of bar a,
by which nuts the brake bar a can be adjusted nearer or further from the
wheels.
An eyebolt is put through centre of axle bar of hind wheels of lorry or other
vehicle & screwed on other side.

page_text: On this eyebolt fis hung an upright iron lever G which lever G is formed with
double iron at the parts where connections are required. The lever G is hung on
eyeboltby a bolt passing through holes in lever G & 1 hole in eyebolt f.
At the lower end of this upright lever G other holes are bored to receive eye
end of the aforesaid screwed rode, which end is coupled by a bolt. The upper end
of this upright lever G is formed double likewise with holes bored & receives eye
end of long connecting rod 1, which end is also coupled by a bolt.
Said long connecting rod I running along under side of bottom of lorry or other
vehicle passes through holes in the upper or stationary portion of lock of lorry or
other vehicle & the said connecting rod I being formed double on the other end is
coupled to the front horizontal lever J'by means of a bolt.
This front horizontal lever J is hung on a bolt fixed on the under side of third
rail from front of lorry or other vehicle & slides in a teethed rack K, which is
bolted on to side of first rail of lorry or other vehicle; the part of horizontal
lever J which slides in teethed rack K being thinned down & formed at an angle
to engage in rack K.
To use this brake the driver while seated or standing at side of vehicle, draws
the lever J forward into rack K & likewise moves the lever J backward to disengage
the brake.
