A PEProved pparatus for
I, FRIEDRICH POLKO, of 34 Bismarkstrasse, Bitterfeld, in the Empire of
Germany, Manufacturer do hereby declare the nature of this invention to be us
follows:-
This invention relates to an improved apparatus for watering trees. In orchards
and avenues of trees along streets it is absolutely necessary for the proper growth
of the trees that their roots shall be supplied with water, and in some instances also
with liquid manures or chemical agents.
In the case of the smaller plants this may very easily. and conveniently be effected
without special appliances. With larger trees, however, the proper and regular
watering presents several difficulties. In the first place it is impossible to supply
the deep roots with sufficient nourishment by simply watering the soil surrounding
the tree, as the nutrious substances are completely absorbed by the upper layers
of earth.
Besides, it is well known that particularly in large towns the soil about trees is
frequently paved over or covered with hard material which provents the moisture
from oozing through. For this reason the soil round trees in streets is often dug
up in summer for the purpose of enabling the watering to be effected, but this work
takes much time and is expensive.
In order to obviate the before mentioned inconveniences and to euable even the
deepest roots to be properly watered, use is made of the improved apparatus
constructed according to the present invention.
Referring to the accompanying drawings―
Figure 1 is a section of my circular watering pipe in position around a tree,
while Figure 2. is a corresponding plan part in section thereof.
Figures 3 and 4 represent respectively semi-circular and oval shaped pipes which
are adopted in certain instances.
The apparatus comprises a pipe & arranged at a certain depth around the tree a
and pierced at the underside and if desired also laterally with holes c. From
time to time the said pipe is regularly filled through the intervention of a stand
pipe f, adapted to be closed by a cover d or of any other appropriate device, with
water or manure which gradually oozes through the aforesaid holes o and penetrates
down to the deepest roots.
0
It is expedient to embed the watering pipe in a stratum of gravel, as this material
allows the liquid to pass through more easily and does not give rise to choking.
The watering pipe may be composed of one
or more parts, such as two
semi-circular paris presenting a round section; its shape and transverse section
may be modified at will, for instance, it may have a polygonal shape and an
oval transverse section. If desired this pipe is arranged only partially round the
stem of the tree.
The stand pipe may of course be constructed in different ways and provided
with any kind of cover, and any other appropriate filling device may be substituted
for it.

1; FRIEDRICH POLKO, of 34 Bismarkstrasse, Bitterfeld, in the Empire of
Germany Manufacturer, 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 relates to an improved apparatus for watering trees. In orchards
and avenues of trees along streets it is absolutely necessary for the proper growth of
the trees that their roots shall be supplied with water, and in some instances also
with liquid manures or chemical agents.
In the case of the smaller plants this may very easily and conveniently be effected
without special appliances. With larger trees, however, the proper and regular
watering presents several difficulties. In the first place it is impossible to supply
the deep roots with sufficient nourishment by simply watering the soil surrounding
the tree, as the nutrious substances are completely absorbed by the upper layers
of earth.
Besides, it is well known that particularly in largo towns the soil about trees
is frequently paved over or covered with hard material which prevents the moisture
from oozing through. For this reason the soil round trees in streets is often dug
up in summer for the purpose of enabling the watering to be effected, but this work
takes much time and is expensive.
In order to obviate the before mentioned inconveniences and to enable even the
deepest roots to be properly watered, use is made of the improved apparatus
constructed according to the present invention.
Referring to the drawings filed with my Provisional Specification.
Figure 1 is a section of my circular watering pipe in position around a tree,
while
Figure 2 is a corresponding plan part in section thereof.
Figures 3 and 4 represent respectively semi-circular and oval shaped pipes which
are adopted in certain instances.
The apparatus comprises a pipe barranged at a certain depth around the tree a
and pierced at the underside and if desired also laterally with holes c. From time
to time the said pipe is regularly filled through the intervention of a stand pipe /,
adapted to be closed by a cover d or of any other appropriate device, with water
or manure which gradually oozes through the aforesaid holes c and penetrates down
to the deepest roots.
It is expedient to embed the watering pipe in a stratum of gravel, as this
material allows the liquid to pass through more easily and does not give rise to
choking. The watering pipe may be composed of one or more parts, such as two
semi-circular parts presenting a round section, its shape and transverse section may
be modified at will, for instance, it may have a polygonal shape and an oval
transverse section. If desired this pipe is arranged only partially round the stem
of the tree.
The stand pipe may of course be constructed in different ways and provided
with any kind of cover, and any other appropriate filling device may be substituted
for it.
Having now particularly described and ascertained the nature of my said inven-
lion and in what manner the same is to be performed I declare that what I
claim is-
1. An apparatus for watering trees, consisting of a watering pipe 6 arranged

page_text: manner, with a stand pipe f, and with lower outlet holes c for the purpose of amply
and directly supplying the water or the liquid manure to the sucking roots and
obviating stoppages.
