Complete Specification Accepted, 23rd Nov., 1888
1, THOMAS GEORGE PASCALL of 27 High Street South Norwood, in the county
of Surrey, Potter, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a combined evaporating and propagating pan for use on the
hotwater pipes of a Hothouse or Greenhouse.
I am aware that evaporating pans have already been made and used in conjunction
with hotwater pipes for throwing off moisture to the air and my invention consists in
the combination therewith of a propagating pan for forcing plants etc.
My propagating pan may either be made to fit existing evaporating pans or it may
be combined with an evaporating pan suitable for use with hot water pipes of any
diameter.
I do not bind myself to the use of any particular material or substance for the
manufacture of my combined evaporating and propagating pan as it may be made of
iron or pottery ware or of a combination of both.
I construct my combined evaporating and propagating pan in the following
manner :-I form a pan or trough with a curved bottom of a crescent shape in cross
section to fit on to round hot water pipes. On the inside of this pan or trough at
about half its depth is formed a small flange or projection, or its equivalent, to receive
and support a flat tile or plate perforated with a number of small holes and one large
hole which is provided with a circular shaft or funnel extending to the total height of
the pan. This funnel serves two purposes, first to admit of water being placed in the
bottom of the evaporating pan to compensate for evaporation, secondly to allow for
the exit of any excess of hot air or moisture. I prefer to form on the top of this
shaft or funnel an adjustable cover or damper so that the amount of hot air or
moisture allowed to escape may be regulated as desired. The top of the pan is
partially filled with mould to receive the young plants or seeds to be propagated and

page_text: if desired the top of the pan may be provided with a glass lid or slide. In the side
of the evaporating pan is formed a small overflow-hole to prevent too much water
being placed in the said pan.
I do not limit myself to the exact construction hereinbefore set forth as my
invention is capable of many modifications. For instance the evaporating and
propagating pan may be made in two distinct parts so that the one may be removed
from the other without disturbing the plants, further the shaft or funnel inay be made
in the lower or outer, that is, in the evaporating part of the apparatus instead of in
the top or inner, that is, the propagating part of the apparatus.

page_text: I, THOMAS GEORGE PASCALL of 27 High Street, South Norwood in the county of
Surrey, Potter, 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 tho
following statement:—
My invention relates to a combined evaporating and propagating pan for use on
the hot water pipes of hot-houses, green-houses, conservatorys, and the like.
I am aware that evaporating pans have already been made and used in conjunction
with hot-water pipes for throwing off moisture to the air, but my invention consists
in the combination therewith of a propagating pan for forcing plants etc.
My combined evaporating and propagating pan may either be made complete, or
the propagating part thereof may be adapted to fit existing evaporating pans.
I do not bind myself to the use of any particular material or substance for the
manufacture of my combined evaporating and propagating pan, as it may be made of
iron, or pottery ware, or of a combination of both.
I construct my combined evaporating and propagating pan in the manner illustrated
in the accompanying drawing in which Figure 1 is a view in longitudinal sectional
elevation of the combined evaporating and propagating pan. Figure 2 is a view in
transverse sectional elevation thereof, and Figure 3 is a broken view in plan thereof.
Figures 4 and 5 are half views in transverse sectional elevation of modifications of
my invention, in which the propagating pan is adapted to be capable of removal
from the evaporating pan, and also for use with existing evaporating pans.
Throughout these views similar parts are marked with like letters of reference.
I form a pan or trough A with its bottom formed of a crescent, or other shape in
transverse section, to fit on to hot water pipes of a round or other section.
On the inside of this pan or trough at about half its depth, are formed small
longitudinal flanges or projections a, a or their equivalents, to receive and support a
flat tile or plate B perforated with a number of small holes b, betc. and with a shaft
or funnel 6 extending just above the total height of the pan. This funnel 6¹ serves
two purposes, first to provide a means of placing water in the evaporating pan without
removing the plate B, to compensate for evaporation, & secondly, to provide an exit
for any excess of hot air or moisture. If desired the top of the shaft or funnel 61
can be fitted with an adjustable cover or damper, so that the amount of hot air or
moisture allowed to escape may be regulated as desired.
In the side of the pan A is formed a small overflow hole a¹ to prevent too much
water being placed in the said pan.
I do not limit myself to the exact construction hereinbefore described as my
invention is capable of many modifications:-for instance the tile or plate B may be
made in the form of a pan as illustrated by Figures 4 and 5 of the accompanying
drawing so that it may be capable of being removed from the lower or evaporating
part A without disturbing the plants.

page_text: Instead of forming the funnel 1 in the centre of the plate or pan B, it may form
part of the pan A by being formed in one corner, or in any other convenient position
therein or thereon.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A combined evaporating and propagating pan, constructed arranged and operating
substantially as set forth.
2. A combined evaporating and propagating pan, consisting essentially of a pan
shaped to rest on or fit over the hot water pipes of a hot-house, green-house, or
the like, and adapted to contain a given quantity of water, of a plate or pan shaped
to fit within or on the top of the said pan containing the evaporating water and
adapted to receive mould or its equivalent for propagating seeds or young plants, and
having perforations whereby the hot air and moisture given off by the water may
pass through the said mould, and of a passage or funnel from the lower pan to
provide for the introduction of water thereto and to regulate the exit of the superfluous
hot air or moisture, as set forth.
3. The combination with the evaporating pan A adapted to fit over, or rest on, the
hot water or steam pipes of hot-houses, greenhouses, and the like, of the perforated
plate or tile B fitting within the said evaporating pan and adapting it for use also as
a propagating pan, as hereinbefore described and illustrated by Figures 1, 2, and 3 of
the accompanying drawing.
4. The combination with the evaporating pan A adapted to fit over, or rest, on the
hot-water or steam pipes of a hot-house, green-house or the like, of the propagating
pan B adapted to fit over the top of the said pan A, as hereinbefore described and
illustrated by Figure 4. of the accompanying drawing.
5. The combination with the evaporating pan A adapted to fit over, or rest on, the
hot water or steam pipes of a hot-house, green-house, or the like, of the propagating
pan B adapted to fit within the pan A, as hereinbefore described and illustrated
by Figure 5 of the accompanying drawing.
6. In a combined evaporating and propagating pan, the combination of the pan A
having two longitudinal flanges or projections a, a, or their equivalents, and the
overflow hole a¹ immediately beneath one of the said flanges, and the plate or pan
adapted to fit within the top of the pan A and rest on the flanges a, a, or their
equivalents, and having a number of holes b, b, etc. formed therein, and a funnel &¹
formed therein with or without a cover or damper, all constructed arranged and
operating as and for the purpose set forth.
