page_text: Figures 4 and 4 a perspective view of two arrangements of floors.
The new covering consists of two parts the upper plate A and the lower plate B
both being made of single plates of burnt clay cement or other similar porous or
suitable material; the lower plate can be formed on the spot by means of concrete
made with cement or by other suitable means.
Both plates A and B are fixed together by cement or otherwise suitably joined
and form at their contact surfaces by means of suitably arranged openings a
somewhat inclined or curved outlet channel these openings being either common
in both plates (Figures 3 and 4) or formed in one of them only (see Figures 3ª
and 4A).
All these outlet channels 6 lead to a common main channel which is likewise
somewhat curved or inclined (Figure 2) and is permanently closed at its upper end
while its lower end is closed by a valve cock or damper k.
The channel or pipe g Figure 2 (which is connected with a cold or warm water
conduit or with a ventilator or other device for supplying warm or cold air as well
as with a steam boiler) supplies the outlet channels 6 by means of the connecting
channels with cold or warm water or with cold or warm air.
The outlet channels lead out of the pipe into the main channel yet it is not
absolutely necessary that these connections should be direct they may for instance
in case the water required for cooling was limited in quantity or was expensive and
for the purpose of making a better use thereof be arranged in pairs or in even
greater numbers and connected by coils or they may be fixed in such a manner as
to wind or form convolutions (Figure 1A) so that the to and fro circulation obtained
may miss one or more outlets.
The closing device provided at the end of the main channel allows of the
admission for the purpose of warming or cooling the floor of any suitable quantity
of warm or cold water i.e. until it reaches the desired height in the outlet channel
whereby the floor covering can be maintained at a uniform temperature and
moisture.
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 malting house floors and other like floors the use of two plates such as A
and B arranged one over the other and forming channels b at their contact surfaces

page_text: which channels are supplied through a suitable pipe or channel such as 9 with water
air or steam and lead to a common channel furnished at one end with a closing
device whereby the height of water in the channel b can be regulated at will
substantially as and for the purposes herein before described and illustrated in the
drawings hereunto annexed.
2. In the floor covering claimed above the serpentine formation of the channels
made by the two plates A and B for the purpose of making better use of the
cooling water and of reducing the number of outlets substantially as and for the
purposes hereinbefore described and illustrated in the drawings hereunto annexed.
3. The modification of the arrangements set forth in Claims 1 and 2 whereby
one plate alone is furnished with the channels & substantially as and for the purposes
hereinbefore described and illustrated in the drawings hereunto annexed.
