Improvements in Steel Lorries and other similar Road Vehicles.
NICOL SINCLAIR ARTHUR, 2 Croall Place, Edinburgh, Midlothian, Ship-
builder, WILLIAM KEDDIE, 2 Cadzow Place, Edinburgh, Midlothian, Railway
Carting Contractors Manager do hereby declare the nature of this invention to be
as follows:-
This invention has for its object improvements in the building of lorries and
other vehicles.
:
The ordinary lorries are built entirely of wood with iron fastenings and fittings.
According to our invention the lorry may be composed entirely of steel consisting
of tubular steel for wheel spokes, shafts and top rim of lorry sides, the framework
of sections of channel, angle, ZT or H steel, the sides of 2 lengths of angle steel
held at top edge by split steel tube.
The forecarriage is built of sections of channel, angle T or H steel and the lock
is of entirely new design, being composed of two rings of angle, channel,
Tor H steel, one working inside the other, one being attached to the lorry top
and one to the forecarriage and the lock takes the whole drawing strain in addition
to allowing the forecarriage to revolve.
The space between the lorry top and hind axle is taken up by an ogee section of
steel to which the springs are attached.
The axles are formed of steel tubes from end to end and plugs may be inserted
a few inches from each end to form an oil channel between the plug and the
ordinary cup for purposes of lubrication, the oil passing thro' perforations made in
the tube.
The wheels, which may be used for any description of vehicle, are made of cast
steel or chilled iron naves into which the spokes are screwed cast or rivetted. The
spokes may be steel tubes or formed of 2 half-round or cope or other sections the
outer ends being bent over and connected to outer rim.
The rim may be of channel or angle steel fitted with the usual iron ring and
wood felloes may be fitted between the rim and the outer ring.
The shafts which may be used for any vehicle are constructed of tubular steel
carrying the usual fittings, the end framing being of channel steel or other suitable
sections, a coach or other suitable spring being placed in the aforesaid framing of
shafts and the drawing chains or traces being attached to a rod passing through
the front cross bar which may be straight or ogee shaped, and connected with the
ends of the aforesaid spring. The breeching chains of harness are passed round.
small pulleys on the shafts and attached to the drawing chains so that the spring
comes into play in pulling and backing the lorry, provision being made for the
drawing chains or rods being instantaneously detached in case of accident. The
Jorry springs which are of the ordinary pattern rest on a rubber cushion which is
introduced between the bottom plate of spring and the axle.
The bottom of the lorry may be strengthened by means of truss rods attached
to the longitudinal members. The cross girders are connected to the sides of the,
lorry. The brakes working on rims of wheels are attached to a vertical lever
working round the axle & controlled from the frout of the lorry by hand screw or
lever or the brake may be a steel band attached to a compound lever and working,
ound a drum on wheel axle,

Tor H sections of steel and the top flange may be angled to the centre and the
slipes finished in the usual way.

We, NICOL SINCLAIR ARTHUR, 2 Croall Place, Edinburgh, Shipbuilder, and
WILLIAM KEDDIE, 2 Cadzow Place, Edinburgh, Carting Contractor Manager,
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:-
This invention has for its object improvements in the building of lorries and
other vehicles.
The invention is illustrated by the accompanying drawings, Figure 1 of which
is a plan, Figure 2 a longitudinal section and Figure 3 a transverse section
of the improved lorry. Figures 4, 5, 6 and 7 are details hereinafter particularly
referred to.
According to our invention the lorry may be composed entirely of steel,
consisting of tubular or channel steel for the shafts A and top rim of the lorry.
sides B, the framework C and wheel spokes being of sections of channel,
angle, Z, or H steel, or the sides B may be of two lengths of angle steel held at
top edge by a split steel tube, or of sheet metal bolted to the framework of the
lorry and turned over in tube form as shown at Figures 2, 3 and 4. The back i
door is permanently attached to the lorry as shown at Figure 2 and is hinged with
long slots which require the door to be lifted up before it can be folded back 'but
which maintain it rigidly-in position when down.
The lock consists of one circle of channel steel E attached to the lorry top F,
working outside a circle G of angle steel attached to the fore carriage H.
The space between the lorry top F and the hind axle carriage I, may be taken
up by an ogee section J of steel to which the springs K are attached, said springs
bearing on the axle as shown at Figure 4, or the springs may be secured to a bridge'
piece L which carries the axle boxes as shown at Figures 2 and 3.
In the example shown at Figure 4 the lorry springs, which are of the ordinary
pattern, rest on a rubber cushion which is introduced between the bottom plate
of spring and the axle.
The axles M which are hollow as shown at Figure 5 have each a brass liḍ
on the top which enables them to be lubricated without removing the cap; and
the wheel naves N are of cast steel or cast iron with a chilled cast iron bush O
fitted into the centre as shown at Figure 5.
"
The wheel spokes S may be made of tubular, flat or beaded steel riveted on to
the rim and cast into the nave, the spokes being alternately spread. at the nave to
give lateral stiffness. The rim is preferably made of channel section of steel
fitted with the usual wearing ring, and wooden felloes may be fitted between .the
aforesaid channel and ring, or the spokes may be formed of half-round or "cope,'
channel or other section bent and cast into the boss, their outer ends being 'bent
over and riveted to the wheel rim as shown at Figures 2 and 4 or held by a clip
as shown at Figures 6 and 7, a pad of rubber being introduced at S to lessen
shock. The wheels may also be made of steel castings with wearing ring shrunk
on and nave bushed if required with chilled iron.
The shafts A which may be used for any vehicle are constructed of tubular or
.

page_text: channel steel carrying the usual fittings, the end framing of the shafts being of
channel steel or other suitable section, a coach spring T being placed in the afore-
said framing of shafts, and the drawing chains or traces are attached to rods U
passing through the front cross bar V which may be straight or ogee shaped said
rods being connected with the ends of the aforesaid spring, and rods U may be
fitted with slip hooks to enable drawing chains to be instantaneously detached in
case of accident. The breeching chain of the harness is passed round a small
pulley P and attached to the drawing chain as shown at Figure 1, so that the
spring T comes into play in pulling and backing the lorry.
The lorry bottom or platform may be of corrugated steel with wooden covering.
The bottom of the lorry may be strengthened by means of truss rods attached
to the longitudinal members.
The brakes working on rims of wheels are attached to a vertical lever
working round the axle and controlled from the front of the lorry by hand
screw or lever.
The lorry slipes for sliding goods off lorry are constructed of angle, channel, T
or H sections of steel and finished in the usual way. The top flange may be
angled to the centre.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A lorry or similar road vehicle the several parts of which are constructed of
steel and arranged or combined substantially as described with reference to the
annexed drawings.
