page_text: 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 :-
The use of earthenware pipes for heating and hot water purposes NA, double spiral
coil boiler N B, Thermometer fixed in pipe NC, expansion pipe with Octagon shaped
collar N D, Water column's Octagon pattern N E, Bell to signal when water boils NF
tap for watering with hose NI, Valve N G, Grating NH to firehole, Octagon flanges
to pipes NJ.
I claim the sole right to use earthenware pipes with Octagon collars for heating
purposes.
Also the double coil spiral boilers.
Also Thermometer fixed in pipe.
Also expansion pipe with rubber joint.
Also Water column's Octagon pattern as conection.
Also Bell to signal by hot water.
Also tap for watering with water by hose from hotwater.
Also Valve in earthenware pipe, a Watertight throtle.
Also Grating to firehole moved by a lever."
The use of Earthenware pipes for heating and hot water purposes, glazed
Earthenware in bronzed or terra cotta having a cleaner appearance than metal pipes,
at the same time they have no tendency to perish by reaction of tempreture, and
being thicker in substance it retains the heat longer than any other pipes that have
been used to convey hot water for heating purposes NA.
Double spiral coil boiler, which is set in brickwork below the surface of the ground
the boiler which is of wrought iron with the lower half in the fire the remaining half
being in the blast it being a double coil it has the advantage over a single one on
account of its working in the same space and having double the heating surface N B.
Themometer fixed in pipes to denote tempreture of water for guidence of stoker
previous to water boiling, or freezing, as it is dificult for even an experienced man to
judge the tempreture of water without such a guide N C.
Expansion pipes with Octagon shaped collar's, these being necessary to allow for
expansion and contraction the pipes having Octagon shaped collar at one end with
cavity around plain end for indiarubber ring, which play's in a round collar inside
and is Octagon pattern outside. The cavity round the pipe pipes will carry the rubber
backwards and forwards working as a Telescope ND.
Water column's Octagon pattern as shewn on plan standing in earthenware tray or
pan, these being all of terra cotta or earthenware, also caps to water columns of the

page_text: same material with hole through for airpipes the same being connected to columns
with cement, likewise the base's and other connections except the expansion joints.
The holes in column's which are not at present required are filled with stop ends
with cavity round for indiarubber rings which can be removed with ease for further
connection's if required from the same saurce of water, having the additional holes
one section will form any connection required which is an improvement on any other
system known N E.
Bell to signal when water boils which is fixed above below pipe marked on plan so
that when the water boil's in the Boiler it will shoot through the blow pipe against a
fan which is attached to the axle of the bell calling attention, by reason of the bell
ringing which is very necessary when water reaches boiling point NF.
Tap for watering with hose which is fixed in return pipe for watering with chilled
water, having Themometer to guide the tempreture and water supplied by ball tap M J
to feeder MK in boiler, which is an improved method of heating water for watering
purposes NI.
Valve which is a watertight throtle fan working in centre of earthenware pipe,
with cavity around edge of fan for indiarubber ring. The fan being cast in metal
with square hole through centre for pin which is also square in the middle a portion
of which passes through the pipe-rubber, and fan the same being made watertight by
small rubber rings let in cavitys in top and bottom of pipes the valve being held in
position by nuts, screwings, and caps, screwed up and down the pin. The handle for
working the valve is regulated to any position by means of pin's and holes which are
cast in the earthenware for that purpose. This Valve has an advantage over, any
other of its class through being provided with regulating gear, also having indiarubber
rings around the edge of fan making it complete as a watertight Valve, which
is highly necessary in case any part of the foundation's should give way or in
case of breakage or other accidents. This Valve can be trusted to work in any
position N G.
Grating to firehole, this is round and in three section's the middle three, bar's
working on an hinge at the back, and lowered and raised at the front by mean's of a
lever fixed for the purpose so that the firehole can be cleaned out and the coils
inspected quickly and with ease, the improvement in this grate its being hinged
and being worked by lever N H.
Octagon pattern collars or flange to pipes is an improvement upon round collar's for
This aparatus as they set neatly upon each other as shewn on plan N J.
MI air pipe Old. MJ ball tap Old. MK feeder Old.
Having now particularly described and ascertained the nature of my said
improvements in hot water apparatus and in what manner the same is to be performed,
I declare that what I claim is my improvements as follows.
