PROVISIONAL SPECIFICATION.
An Improved Protector for Preventing Floors, Ceilings, or the like
Structures or Parts of Buildings from being Overheated by
Flues.
I MATTHEW PARSONS of the Oxbridge Hotel Stockton-on-Tees in the County
of Durham Innkeeper do hereby declare the nature of this invention to be as
follows:-
My invention relates to protectors for preventing floors ceilings or the like
structures or parts of buildings from becoming overheated by flues such as the
metal pipes in ordinary use for conveying the products of combustion from stoves to
some outlet above, which flues are liable to become too hot to be safely placed in
direct contact with the materials employed in the construction of such floors
ceilings or the like structures or parts of buildings.
At present such flues are passed through vessels or chambers fixed in the floor
or other like structure where the direct contact is to be avoided, which vessels are
charged with sand to serve as a non conductor of the heat from the flue. Owing
to constant vibration such as arises from vehicular traffic or the like causes the
sand which originally filled the said vessel or chamber undergoes a constant
process of consolidation until the vessel or chamber becomes partially empty
leaving so much surface of the hot flue within the said chamber unprotected by
sand.
The object of my invention is to overcome this defect by substituting a water
chamber for the sand chamber as hitherto used to which a constant supply of
water is maintained by the circulation excited by the heat absorbed from the Hue.
My invention consists as follows:-A chamber or vessel of any convenient form
such as a cylinder is provided in the floor or like structure as an attachment to the
flue which passes through it, the intervening space forming a close chamber or
vessel for the reception of water. Pipes communicate with this chamber at
different levels, one being the delivery pipe from a tank or other convenient
source of supply, whilst another is the return pipe. By this arrangement which
can be readily modified or designed to suit the particular circumstances of each
case, the water vessel can be kept constantly full of water from a supply tank by
the circulation due to the heat absorbed from the flue.

COMPLETE SPECIFICATION.
An Improved Protector for Preventing Floors, Ceilings, or the like
Structures or Parts of Buildings from being Overheated by
Flues.
"I, MATTHEW PARSONS, of the Oxbridge Hotel, Stockton-on-Tees, in the
County of Durham, Innkeeper, 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 protectors for preventing floors, ceilings, or the like
structures or parts of buildings from becoming overheated by flues such as the
metal pipes in ordinary use for conveying the products of combustion from stoves
to some outlet above which flues are liable to become too hot to be safely placed in
direct contact with the materials employed in the construction of such floors,
ceilings, or the like structures or parts of buildings.

page_text: At present such flues are passed through sand box protectors which are vessels
or chambers fixed in the-floor or other like structure where the direct contact is to
be avoided and which are charged with sand to serve as a means for intercepting
the heat from the flue. Owing to constant vibration such as arises from vehicular
traffic and the like causes the sand which was originally charged into the said
vessel or chamber to its full capacity undergoes a constant process of consolidation
until the vessel or chamber becomes partially empty, leaving so much surface of
the hot flue within the said chamber unprotected by sand.
The object of my invention is to overcome this defect by substituting a water
chamber for the sand chamber as hitherto used, to which a constant supply of
water is maintained by the circulation excited by the heat absorbed from the flue
or other equivalent means.
And in order that my invention may be clearly understood and readily carried
into effect, I will now proceed to describe the same with reference to the
accompanying drawing, in which Figure 1 illustrates a general view of a stove a
and flue passing through a floor e to some outlet above, which stove and flue are
to be taken as representatives of stores and flues generally to which my invention
is applicable. d'is a vessel or water box for protecting the floor c which the flue b
is shown to pass through, and e is a tank of water placed at any convenient
position above the water box d, to which it is connected by the supply pipe / and
return pipe g. Figures 2 and 3 are drawn to a larger scale than Figure 1.
Figure 2 being a sectional view of my improved water box protector shown in
position in the floor. Figure 3 is a similar sectional view of a sand box
protector das at present in use showing how the sand settles down and
leaves the parts / empty. In Figures 1 and 2, the water box d which
is of any convenient form, such as a cylinder, and which is provided as an
attachment to the flue b, which passes through it is charged with a constant
supply of water as a substitute for sand. The tank e being provided and
connected with the water box d as shown in Figures 1 and 2, that is with the
delivery pipe extending deeper into it than the overflow pipe 9, it will be found
that the heat absorbed into the water and which would otherwise generate steam
sets up a current which circulates from the tank e down the pipe finto the water
box and up the pipe g to the tank again, the water box d being charged to its
full capacity with water which is constantly absorbing the heat from the flue b.
k is a cock for clearing the vessel d from time to time to prevent deposit. It will
be understood that although Figures 1 and 2 clearly illustrate the main features of
my invention, I do not restrict myself to the precise arrangement shown which
merely illustrates the application of my said invention which may obviously be
modified to suit the requirements of each case so long, as the water box d is
charged to its full capacity with a constant supply of water.
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 :-
For the prevention of floors, ceilings or the like structures from becoming
overheated by flues, the use of a water box as an attachment to the flue, which
water box is charged to its full capacity with a constant supply of water, substan-
tially as and for the purpose as herein before described and illustrated by way of
example in the accompanying drawing.
Dated this 24th day of October 1892.
