IMPROVEMENTS IN GARDEN ENGINES
Year: 1884

do hereby declare the nature of my invention for IMPROVEMENTS IN GARDEN
ENGINES to be as follows:—
The object of the present invention is so to construct a garden engine as to
obtain a continuous stream of water without the labour of continuous pumping.
In the upper part of the rising main of a garden engine of the ordinary construc-
tion I fit a nozzle to which I fix a vertical tube that extends to near the bottom of
the tank of the garden engine, constituting a supplementary supply pipe.
pipe is provided with a cut off cock. To the rising main above this nozzlo I fit
by a union or other suitable means, a piece of hose long enough to allow of its
delivering the water below the level of the bottom of the supplementary supply
pipe.
This
When the tank of the engine is filled and ready for use I turn off the cock above
mentioned and make a few strokes with the pump handle thereby forcing the
water through the rising main in the ordinary manner; I then open the cock in
the supplementary supply pipe, when the water will immediately rise by syphonage
and be delivered through the hose to the ground the delivery continuing as long as
any water remains in the tank without any further pumping.
As it is necessary to ensure the maintenance of the syphonage, that the delivery
end of the hose should be held below the level of the bottom of the supply pipe,
I provide a hose holder of wire or other suitable material into which the delivery
end of the hose can be tucked for the purpose of holding it at the required level.

I EDGAR NEWTON of Hitchin in the County of Herts, Horticultural Builder
do hereby declare the nature of my invontion for IMPROVEMENTS IN GARDEN
ENGINES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of the present invention is to construct a garden engine in such a
way that a continuous stream of water can be obtained from it without the labour
of continuous pumping.
To this end I mount a water tank upon wheels and place within the tank the
common force pump arrangement of an ordinary garden engine. The force pump
I supplement with a syphon arrangement which when set in action by a few
strokes of the pump handle will deliver an even stream suitable for watering
bedded out plants as long as any water remains in the tank.
In the accompanying drawing Fig. 1 is a side elevation partly in section of a
garden engine of the ordinary construction showing my invention applied thereto
and Fig. 2 is a plan view of the same with the cover removed.
A is the tank of a garden engino in which is mounted a force pump B of the
ordinary or any approved construction. C is the main pipe of the rising main
connected with the barrel of the force pump and fitted at bottom with a stop
valve.
The upper end of this pipe is closed by a cap through which passes a dip pipe C¹
of smaller diameter than the pipe C, the two pipes C and C forming together a
rising main of the ordinary construction.
Upon the upper end of the dip pipe C¹ is screwed a hollow casting c from the
side of which protrudes a branch pipe & bent in a downward direction; coupled
to this pipe by means of a union is a supplementary supply pipe D which dips
into the tank and nearly reaches the bottom and is intended to act on the principle
of a syphon to maintain a supply of water to the delivery hose while the force
pump is quiescent.
This supply pipe D is fitted with a cut off cock d'. A hose E of sufficient
length to allow of its delivering water at a level below the bottom of the supply
pipe is attached by means of a suitable elbow piece and union to the upper end
of the casting c.
The action of the apparatus is as follows-
On the tank being charged with water and ready for use I close the cock d¹ and
make a few strokes with the handle of the pump B thereby forcing the water
through the rising main C C¹.
While the flow of the water is proceeding I open the cock d' when the water
will immediately rise by syphonage in the supply pipe D and be delivered through
it to the hose, the delivery continuing as long as any water remains in the tank,
without any further pumping.
As it is necessary to ensure the maintenance of the flow, that the delivery end
of the hose should be held below the level of the bottom of the supply pipe, I
provide a hose holder of wire or other suitable material into which the delivery
end of the hose can be tucked for the purpose of holding it at the required level.

page_text: 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
The adaptation to the force pump of a garden engine of a supplementary supply
pipe for maintaining a continuous supply of water to the delivery pipe, in the
inanner and for the purpose above set forth.
