I PHILIP JOSEPH PARMITER farmer of Harwood farm Ansty, near Salisbury
Wilts do hereby declare the nature of the invention for an IMPROVED COMBINED
TRACTION ENGINE AND TRUCK "
FOR TRAVELLING ON COMMON ROADS OR ON LAND
to be as follows :-
:
The main wheels of the engine to which motion is given are made to carry the
truck, the load to be moved will thereby increase the wheel-grip on the
road and smooth wheels can be used instead of ribed ones. That which. I'
particularly claim as my invention is the meathod of construction and design of
apparatus as shown in the drawing. (N° 1. 1) are the connecting rods giving
motion from the crank shaft to the rachet leavers 2. 2; four would be used two
actuating each wheel the travelling speed can be increased or diminished by moving.
connecting rods up or down the rachet leavers. 3. 3 show the truck in position
an tiped. The wheels will be made of appropriate width. Further particulars
in complete specifications.

COMPLETE SPECIFICATION.
I PHILIP JOSEPH PARMITER of Harwood in the parish of Ansty in the County of
Wilts farmer do hereby declare the nature of my invention for AN IMPROVED
COMBINED TRACTION ENGINE & TRUCK, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention is the invention for which Provisional Protection was granted to
me Philip Joseph Parmiter on March 22 1884, improved: the amendment being
that I do not claim as my particular invention any description of gearing or means

page_text: of conveying motion from the crank shaft marked in the drawings F in (Fig 1) to
the main travelling wheels A 3 in (Fig 1) such motion being given by the ordinary
cog gearing shown in the drawing and now commonly used for the same purpose in
all traction engines.
The invention relates in the first place to the mode of constructing the carriage
and road wheels of a traction engine and secondly to the design of construction and
method of tipping a truck supported on the same carriage and wheels. In the
drawing (Fig 1) A on the plain lines is the Truck in position for travelling A on
the dotted lines the Truck tipped in position for unloading. B the frame-plates
supporting the Truck and engine on the inain wheels A 3. C the worm wheel and
cog for lifting Truck. D the tender from which the engine is fired and steered.
E is the gearing giving motion from the crank shaft of the engine to the main
traveling wheels A 3. In the drawing (Fig 2) A on dotted lines is the position of
Truck over driving wheels. A 1, A 2, A 3 are the main travelling wheels on which
the Truck and engine are carried, the center roller wheel A 2 receiving motion from
the cog gearing E, A 1 & A 3 thence receiving motion from the main axle shaft G.
C is the worm and cog spindle for lifting Truck D the tender for firing and
steering.
The object of the invention is that by combining the Truck with the engine as
shown in the drawings the load and engine are better under the command of the
driver and that by carrying the weight of the engine and truck load on the broad
wheels A 1 A 2 A 3 such wheels would act on the roads with the same effect as a
road roller and enable the engine to take its load on to lands without damaging the.
same or sinking. Without the truck, the engine could be used for land rolling or
drawing any cultivating implement.
The apparatus as shown in the drawings may be subjected to any simple
modification, such as a fixed truck or a truck to tip sideways provided such are
arranged is in combination with the engine as shown in the drawings. I wish it to
be understood that I do not claim as my invention the arrangement of the engine
described and illustrated in the drawing or any form of engine and boiler, as the
engine and boiler may be vortical or of any other form but iny invention consists
in the method of constructing the tipping truck and the main driving wheels taking
the weight direct, as hereinbefore described.
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 The mode of constructing the carriage and three main driving wheels so that
they will carry the combined weight of the engine and truck as shown in the
drawings.
2 The design and method of constructing the tipping truck supported and hinged
on the frame plates B.B.
