PROVISIONAL SPECIFICATION.
Improvements in Horticultural Pots for Flowers and Plants.
I, ALFRED CHANDLER, of Penrose, Wolborough Hill, Newton Abbot, in the
County of Devon, Horticulturist, do hereby declare the nature of this invention
to be as follows:-
My invention relates to the construction of pots, for containing flowers, plants,
trees, bulbs, seeds, or other horticultural purposes and the said invention consists
mainly in certain improvements in metal pots of the class described in the
Specification of my Letters Patent No. 16837 of 9th September 1895.
My said improved pots are constructed substantially in the following manner.
The sides and bottom of the pot are formed of thin sheet metal, such, for
example, as tin plate, terne plate, sheet iron, steel, zinc, or other suitable metal :
and I adopt the method of galvanising the black sheet iron, or black steel plates,
after the pot is made.
The sides may consist of one two, or more pieces of sheet metal, cut and bent
to the required shape, and joined together in any suitable and secure manner.
A bead, or corrugation is formed around the top edge of the pot, and a metal
hoop, or ring of curved, or other suitable form in cross section is placed within the
said corrugation.
The pot when made in black sheet iron, or black steel plates, is preferably
galvanised, which has the effect of securing the said ring firmly in place, otherwise
the ring may be soldered into the corrugation, and in either case the said ring, in
combination with the corrugation, greatly increases the strength, solidity and
stiffness of the rim of the pot, the galvanising process also preserving the metal
plates from rust and corrosion.
The bottom of the pot consists of a disc of sheet metal secured to the lower
edges of the sides by a lap or beaded joint, or in any other suitable manner, and
the joint may be further strengthened, especially in pots of large size, by angle
pieces or brackets, riveted to the said bottom and sides.
Drainage holes are formed near the edges of the bottom, and in the sides near
their lower edges, and the said bottom is raised in the centre, so that the water
can run off freely to the said holes, while a drainage hole is provided in the centre
of the said raised bottom, which is thus kept well off the ground, so facilitating
the escape of any excess of water.
Near the upper part of the pot two handles are riveted, or otherwise secured to
the sides, the said handles being opposite to each other. They each consist of a metal
loop curving upwards and then downwards, in such form that they may be readily
grasped by the hand, and will also hook over a rod or pole, so that a heavy pot
can be conveniently carried by two men with two poles, after the manner of a
sedan chair.
The pot is painted, or otherwise coloured to imitate an ordinary crock, or earthen-
ware pot in appearance. For this purpose I prefer to employ Venetian red mixed
with terebene, bowdered pumice stone, Portland, Roman or other cement being added

to give a rough surface and bring the paint to the right tint. The paint is applied
over the whole external surface, but need only be carried part of the way down the
interior surface. Before applying the above I paint the pot all over, inside as well
as out, with liquid Portland, Roman or other cement in the form of a wash, to
preserve the galvanised metal from corroding.
As an alternative to the above paint mixture, I may use Portland, or Roman cement,
Venetian red and powdered pumice stone mixed in about equal proportions, and
make these said powdered substances, into a wash or paint, with either water,
terebene or other suitable fluid, and wash or paint the same all over the outsides
and insides of the pots to preserve the metal from rust and corrosion.
The pots when made in graduated sizes pack within each other, thus enabling
a large number to be contained within a small space and so rendering them
particularly suitable for export, or transport purposes.
The main advantages of these metal pots over the old clay, or crock pots consist
in their lightness, they being about four times less in weight than clay pots; that
they are in large sizes cheaper than the clay pots that they last longer, being
unbreakable; that they only require about half the labour in watering, the
loss by evaporation being reduced to a minimum, while the drainage is perfect:
that they do not grease or ⚫ moss
on the outside, either in a hot or cool
greenhouse, and that a slight galvanic action is induced, which stimulates the roots
of the plants.

Improvements in Horticultural Pots for Flowers and Plants.
I, ALFRED CHANDLER, of Penrose, Wolborough Hill, Newton Abbot, in the
County of Devon, Horticulturist, 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:-
My invention relates to the construction of pots, for containing flowers, plants,
trees, bulbs, seeds, or other horticultural purposes, and the said invention consists
mainly in certain improvements in metal pots of the class described in the
Specification of my Letters Patent, No. 16837, of 9th September, 1895.
In the accompanying sheet of drawings, which forms part of this specification
and illustrates the mode of carrying my invention into practice;
Fig. 1 is a perspective elevation of a pot constructed in accordance with my
invention.
Fig. 2 is a sectional elevation through A, A, in Figs. 3 and 4.
Fig. 3 is a top plan, and
Fig. 4 is a bottom plan of the said pot.
The
Similar letters of reference denote similar parts throughout the drawings.
The sides B, B, and the bottom C of the pot are formed of thin sheet metal, such,
for example, as tin plate, terne plate, sheet iron, steel, zinc, or other suitable metal.
The said sides may consist of one, two, or more pieces of sheet metal, cut and bent
to the required form and joined together in any suitable and secure manner.
pot shewn in the drawing is made of two pieces joined by vertical seams D D.
A bead or corrugation E is formed around the top edge of the pot, and a metal
hoop, or ring of curved, or other suitable form in cross-section is placed within the
said corrugation.

page_text: The pot, when formed of black sheet iron, or black steel plate, is preferably
galvanised after being made, which has the effect of securing the said ring firmly
in place and also preserving the plates from rust and corrosion. When the pot is
not galvanised, the ring may be soldered, or riveted into the corrugation, and in
either case the said ring, in combination with the corrugation greatly increases the
strength, solidity and stiffness of the rim of the pot.
The bottom of the pot consists of a disc C, of sheet metal, secured to the lower
edges of the sides by a lap, or beaded joint J, or in any other suitable manner,
and the joint may be further strengthened, especially in pots of large size, by angle
pieces or brackets K, riveted to the said bottom and sides.
If preferred, the sides, or the sides and bottom also, may, especially in pots of
small size, be made without a seam or joint by stamping or pressing out of one
piece of sheet metal.
Drainage holes L are formed near the edges of the bottom, and in the sides near
their lower edges, and the said bottom is dished, or raised in the centre, as shewn
clearly in Fig. 2, so that the water can run off freely through or from the said holes,
while a drainage hole M is provided in the centre of the said dished bottom,
which is thus kept well off the ground to facilitate the escape of any excess of
water.
Near the upper part of the pot two handles are riveted, or otherwise secured to
the sides, the said handles being opposite to each other.
They are formed of rod or stout wire, and each consists of a straight portion N,
and curved ends P, P, as shewn, being of such form that they may be readily
grasped by the hand, and will also hook over a rod, or pole (as indicated by the
datted circle Q in Fig. 2) so that a heavy pot can be conveniently carried by two
men with two poles, after the manner of a sedan chair.
I apply to the pot a rough preservative paint of terra-cotta colour, to imitate an
ordinary crock or earthenware pot in appearance. For this purpose, I prefer
to employ Venetian red mixed with tercbene, powdered pumice stone, Portland,
Roman, or other cement being added to give a rough surface and bring the paint
to the desired tint. A dull gray colour of artistic shade may be employed instead
of the terra-cotta colour, if preferred. In preparing the paint, I do not confine
myself to any particular proportions in mixing the ingredients, but either of the
following recipes are found to give a good result in practice.
No. 1. 1 oz. of Venetian red, ochre, or other suitable colouring matter.
7 lbs. of pumice stone, or cement.
gal. (4 lbs.) of terebene.
No. 2. 10 parts of Venetian red, or red ochre.
"
of yellow ochre.
4
"
of pumice stone, or cement.
1
of tercbene.
"
The paint is applied over the whole external surface, but need be carried only
part of the way down the interior surface.
Before applying the above, I paint the pot all over, inside as well as out, with
liquid Portland, Roman, or other cement, in the form of a wash, to preserve
the galvanised metal from corroding.

The main advantages of these metal pots over the old clay, or crock pots, consist
in their being about one quarter the weight of clay pots; that in large sizes they
are cheaper that they last longer, being practically unbreakable; that they only
require about half the labour in watering, the loss by evaporation being reduced to
a minimum; that the drainage is perfect; that they do not "grease" or
the outside, either in a hot or cool greenhouse, and that no parasitic growth will
attach to them; that they cannot break through frost, and can therefore be left
out of doors in cold weather, as, for example, in the case of strawberries, where it
s necessary to leave the plants outside till wanted in the forcing house; that they
nduce a slight galvanic, or electrical action on the acids of manure, which

page_text: stimulates root growth and gives colour and robustness to foliage, flowers and
fruit that they give more soil room than clay pots; and lastly, that when made in
graduated sizes, they pack within each other, thus enabling a large number to
be contained within a small space, so rendering them particularly suitable for
export, or transport purposes.
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. In a pot of the class described, a bead or corrugation E formed around the
top edge and a metal hoop, or ring F secured within the said bead, substantially
as and for the purpose herein set forth.
2. In a pot of the class described, metal handles secured to the sides thereof,
substantially as and for the purpose herein set forth.
3. A metal pot, constructed substantially in the manner and for the purposes as
herein described and illustrated in the accompanying drawings.
