Improvements in Road Vehicles and in Motors therefor.
We, WILLIAM SIMPSON, of 8, Minshull Street, Manchester, Cotton Manu-
facturer, WALTER LIGHT BODMAN, of Village View, Burnage Lane, Didsbury,
Manchester, Carriage Builder, and DANIEL HARRISON SIMPSON, of One Oak,
Cheadle Hulme, in the County of Chester, Engineer, do hereby declare the
nature of our said invention to be as follows:-
It relates chiefly to a novel construction of motor lurry for the conveyance
of heavy freights, some parts of which are separately applicable to other
vehicles.
In accordance with our invention we arrange beneath the level of the lurry
body a set of girder-like frames, from, or by which, we sustain the engines for
propelling the vehicles and the several working parts identified with the engines,
using also parts of the space enclosed by, or surrounding the girders, as
bunkers for holding fuel, and another part as a tank or reservoir for holding
the supply of water for the boiler.
The boiler is of the "flash" type, and, by preference consists of a nest
of tubing indented under the "Kow" system according to Letters Patent
No. 15192/91, and such boiler is placed at the rear end of the lurry so that the
front of the lurry is clear of all obstruction, and the dead load is always well
over the driving wheels. The boiler is also, by preference heated by fuel fire,
and encased with fire-proof material. The water is fed to the boiler from the
supply tank by a hand pump in starting, and afterwards by a pump operated
by a cam on one of the wheels of the lurry.
The pipe for conveying the water to the boiler passes through a steam chest
connected with the live steam outlet of the boiler so that the reciprocal effect
between the feed-water and super-heated steam may maintain the steam at an
equable temperature.
The steering gear comprises a vertical rod or post at the front of the lurry,
with winch-handle or wheel at the upper extremity, and a drum or pulley at
the lower extremity, around which latter oppositely wound cords or chains pass
connected respectively to the ends of swivel arms mounted upon vertical fulcra
carried by the axles of the front wheels. The axle-tree is also connected to
the same fulcra, and is mounted between a set of oscillating beds upon a hori-
zontal pin. The said beds are connected to the rear wheel axle by perch or side
bars, and carry the lurry through the medium of laminated springs lying length-
wise of the lurry.
There are two engines, with crank shafts in line with each other, but dis-
connected, and acting independently of each other, one upon the right hand
side driving wheel and the other upon the left hand side driving wheel of the
lurry, through the medium of strong pitch chains and toothed rims on the
wheels, or through spur gearing, or a combination of spur and chain gearing.

page_text: The engines are by preference mounted in a tank common to both.
For automatically draining the engine cylinders and to form air valves to
relieve back pressure we provide each cylinder with non-return valves and
arrange such valves in an inverted position, so that when there is no pressure
in the cylinders the valves fall away from their seatings.

Improvements in Road Vehicles and in Motors therefor.
We, WILLIAM SIMPSON, of 8, Minshull Street, Manchester, Cotton Manu-
facturer, WALTER LIGHT BODMAN, of Villiage View, Burnage Lane, Didsbury,
Manchester, Carriage Builder, and DANIEL HARRISON SIMPSON, of One Oak,
Cheadle Hulme, in the County of Chester, Engineer, 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:-
It relates chiefly to a novel construction of motor lurry for the conveyance
of heavy freights some parts of which are separately applicable to other
vehicles.
The accompanying drawings illustrate such construction, Fig. 1 being a side
elevation, Fig. 2 a plan (below the level of the lurry body) and Fig. 3 a front
or end elevation.
Figs. 4 and 5 illustrate a certain detail separately.
In accordance with our invention we arrange beneath the level of the lurry
body (A) a set of girder-like frames (B) from, or by which we sustain the
engines (C) and the several working parts identified with the engines. Parts
also of the space enclosed by, or surrounding the girders are used as bunkers for
holding fuel, and another part encloses a tank or reservoir for holding the
supply of water for the boiler (D).
The boiler (D) is of the "flash" type, and by preference consisting of a nest
of tubing indented under the "Row" system according to Letters Patent
No. 15192/91 and such boiler is placed at the rear end of the lurry so that the
front of the lurry is clear of all obstruction and the dead load
over the driving wheels.
always well
The boiler is, by preference, heated by fuel fire, and encased with fire-
proof material. The water is fed to the boiler from the supply tank by a hand
pump in starting, and afterwards by a pump operated by a cam on one of the
wheels of the lurry. The pipe for conveying the water to the boiler passes
through a steam chest connected with the live steam outlet of the boiler, so
that the reciprocal effect between the feed water and super-heated steam may
maintain the steam at an equable temperature. The principle and details of
this last named feature are clearly set forth by the specifications and drawings
of Letters Patents No. 4485/98 and 4486/98 and do not require further descrip-
tion, their mention here only being in relation to the general construction.
The steering gear comprises a vertical rod or post (E) at the front of the
lurry with a winch-handle or wheel (F) at its upper extremity, and at its lower
extremity identified with a pulley (G) around which latter cords or chains (H)

page_text: pass connected respectively to the extremities of swivel arms (I) mounted upon
fulcra (J) carried by the axles of the front wheels. The axle-tree (K) is
mounted between a set of oscillating beds (L) upon a horizontal pin (1).
The said beds (L) are connected to the rear wheel axle by perch or side
bars (M) and carry the lurry through the medium of springs (N) lying length-
wise of the lurry..
There are two engines with crank shafts in line with each other, but dis-
connected and acting independently of each other, one acting upon the right
hand side driving wheel and the other acting upon the left hand side driving
wheel of the lurry through the medium of strong pitch chains (0) and toothed
rims (P) on the wheels, or through spur gearing, or a combination of spur and
chain gearing.
For automatically draining the engine cylinders and to form air valves to
relieve back pressure we provide each cylinder with non-return valves (see
Figs. 4 and 5), and arrange such valves in an inverted position so that when
there is no pressure in the cylinders the valves fall away from their seatings.
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:-
1 In motor driven road vehicles a girder-like frame which presents a clear
level upon which the body of the vehicle may be super-imposed, and from
which the engines and working parts are sustained, and parts of which may be
used as bunkers for fuel, and a water reservoir, substantially as herein set forth.
2: In motor driven road vehicles, a girder-like frame, a boiler placed at
the rear end and directly over the rear axle of the vehicle, engines sustained
from said frame independent of each other, and geared up to the rear wheels
of the vehicle, substantially as herein set forth.
3: In motor driven road vehicles, a girder-like frame supported on front
and rear axles through the medium of springs and oscillating beds on a fulcrum
carried by the front axle tree, a steering post and pulley, cords or chains around
said pulley connected to armis carried on the wheel axles which are pivoted to
the axle-tree, substantially as and for the purposes set forth.
4: In motor-driven road vehicles, the combination and arrangement of parts,
substantially as herein set forth.
