nature of this invention to be as follows:-
This invention has for its object the construction of a portable engine combined
with a centrifugal pump in such a manner as to facilitate the pumping of water for
the irrigation of land and other purposes.
There have been several methods devised for carrying centrifugal pumps on portable
or traction engines but they are all so placed that the pumps have to lift the water
higher than is necessary.
By my invention the pump is so carried on the front of the engine that it can be
lowered below the level of the engine wheels when pumping and raised clear of the
ground and draw bar when the engine is travelling. The pump is driven by a belt
from the fly wheel of the engine and is carried in such a manner that the suction and
delivery pipes can be placed at any angle.

page_text: I DAVID GREIG of Leeds in the County of York 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 :-
This Invention has for its object the construction of a portable engine combined
with a centrifugal pump in such a manner as to facilitate the pumping of water for
the irrigation of land and other purposes.
There have been several methods devised for carrying centrifugal pumps on portable
or traction engines, but they are all so placed that the pumps have to lift the water
higher than is necessary. By my invention the pump is so carried on the front of
the engine that it can be lowered below the level of the engine wheels when pumping,
and raised clear of the ground and draw bar when the engine is travelling. The
pump is driven by a belt from the fly wheel of the engine and is carried in such a
manner that the suction and delivery pipes can be placed at any angle.
Figure 1 is a side elevation and Figure 2 a plan of a portable engine and pump
combined as above described.
A is a centrifugal pump carried by trunnions at one end of a frame B which at its
opposite end is jointed to the front end of a portable engine of ordinary type.
The frame B can be raised or lowered by a chain C-one end of this chain is fixed
to the frame and the chain is led upwards from this point over a pulley D carried in
front of the top of the smoke box of the engine and then downwards and secured to a
winding barrel E upon the frame. The winding barrel has upon it a worm wheel F
into which gears a worm G. By turning the worm by the crank handle H on its
axis the chain can be wound on to or unwound from the barrel and the frame be so
raised or lowered. I is a belt by which the pump is driven from the fly wheel of the
engine. The pump can be set with its suction pipe descending vertically downwards
as shewn or it can be set at any desired angle and be then secured by bolts passed
through the sides of the frame and collars on the trunnions. The delivery is as shown
led away at one side of the engine.
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. Mounting a centrifugal pump on the front end of a portable engine in such
manner that it can be lowered below the level of the engine wheels when pumping
and be driven by a belt from the fly wheel of the engine, and when required to be
removed can be raised clear of the ground.
2. A combined portable engine and pump arranged substantially as hereinbefore
described and illustrated in the drawing annexed.
