* IMPROVED HEATING APPARATUS SPECIALLY ARRANGED FOR FACILITATING THE
CONVEYING AND DELIVERING OF HEATED WATER AND OTHER LIQUIDS."
"
This Invention consists of arrangements for heating water or other liquids in a
boiler which is constructed preferably on the plan for which we obtained Letters
Patent bearing date the 22nd of June, A.D. 1878, No. 2498, and conveying and
delivering the water or other liquids so heated.
In carrying out our Invention we adopt mainly the following arrangements :-
The water or other liquid is conveyed as heated by a pipe from the boiler or
vessel in which it is heated, one end being connected to the lower part of the boiler
and the other to the upper part. The water being heated flows from the upper
outlet and circulating through a pipe descends to the bottom of the boiler and enters
again by the lower inlet. An outlet is provided at the top or highest part of the
pipe (which is preferably arched) for the delivery of the hot water or liquid. This
outlet also serves for the escape of steam and expanded water. Below the outlet of
Din o71

page_text: the pipe or in other convenient position is situated a table or stand provided with a
grating on which a glass, or cup, or any vessel is placed to receive the hot water or
liquid.
This table or stand communicates by a pipe stem, shaft, or spindle, to a four way
cock, so that by turning the table or stand partly round it actuates the plug of the
cock, turning on the cold water to the boiler (which enters by the lower inlet or a
separate inlet) and the supply of gas to the burners. A small gas burner is used
independently of the main burner or burners in order to ignite the said burners
when turned on by the table, and this independent burner will also assist in keeping
up heat.
A pipe which forms the stem of the table and a continuation of the plug
of the fourway-cock is hollow and terminates in a gland box or other suitable
arrangement made water tight by packing. This drains away the drippings from the
delivery outlet of the pipe. Those arrangements it is evident can be used
for heating and conveying water so heated for baths, lavatories, and such like
purposes.

said Samuel Mart and Charles Wallace Bradley in the Great Seal Patent
Office on the 1st September 1879.

"IMPROVED HEATING APPARATUS SPECIALLY ARRANGED FOR FACILITATING THE
CONVEYING AND DELIVERING OF HEATED WATER AND OTHER LIQUIDS."
This Invention consists of arrangements for heating water or other liquids and
conveying and delivering the water or other liquids so heated applicable to a suitable
boiler preferably of that construction for which we obtained Letters Patent in the
year Eighteen hundred and seventy eight, No. 2498.
When the water heated is to be delivered the water or other liquid is conveyed
as heated by a pipe from the boiler or vessel in which it is heated, one end being
connected to the lower part of the boiler and the other to the upper part.
The water being heated flows from the upper outlet, and circulating through a
pipe descends to the bottom of the boiler and enters again by the lower inlet.
An outlet is provided at the top or highest part of the pipe (which is preferably
arched) for the delivery of the hot water or liquid. This outlet also serves for the
escape of steam and expanded water. Below the outlet of the pipe or in other con-
venient position is situated a table or stand provided with a grating on which a
glass, or cup, or any vessel is placed to receive the hot water or liquid. This table
or stand communicates by a pipe, stem, shaft, or spindle to a four way cock, so that
by turning the table or stem partly round it actuates the play of the cock, turning
on the gas to the burners, and by a further turn cold water to the boiler (which
enters by the lower inlet or a separate inlet). Instead of the table or stand turning,
same can be stationary, the plug of the cock being actuated by a lever or handle.
A small gas burner is used independently of the main burner or burners in order to
ignite the said burners when turned on by the table, or lever, or handle, and this
independent burner will also assist in keeping up heat. A pipe which forms the
stem of the table and a continuation of the plug of the four way cock is hollow and
terminates in a gland box or other suitable arrangement made water-tight by
packing. When the stand or table is stationary an outlet is provided, as shown in
the Drawing, thus draining away the drippings from the delivery outlet. These
arrangements it is evident can be used for heating and conveying water so heated
for baths, lavatories, and such like purposes.

Fig. 16. Elevation of heater for baths. Fig. 17. Plan.
In all these Figures,―
A represents the heater or boiler; B, inlet of cold water to boiler; C, outlet
of water as heated; D, pipe or tube through which the water as heated
circulates.
E, outlet at the highest part of the pipe D for delivery of the hot water or
liquid through outlet Ĕ¹.
F, pipe through which the water passes back into the heater or boiler A.; G, table
or stand furnished with grating on which when the heated water is required the
glass or other receptacle is placed.
H, lever or bandle for actuating the four way cock, or, when required, the table
or stand G.
I, four way cock, which is shown in detail in Figs. 8 to 15, which governs the
supply of gas, and also water or other liquid; K, pipe conveying gas to small pilot
burner, which is kept burning under the heater or boiler, said pilot light being
independently supplied with gas; L, main pipe for supply of gas. When a supply
of hot water is required the glass or receptacle is placed on the stand G. The lover
or handle H is then partly turned round, which action actuates the plug a of the
four way cock, bringing the openings c¹, c, in the plug a in communication with the
pipe L, through which the gas passes by said pipe L to the burners M, where the
gas is ignited by the pilot light. The extra heat thus generated heats the water
contained in the boiler or heater A. To deliver the water heated the handle or
lever H is further turned, which brings the opening & in the plug a in a direct line
with the opening in the supply pipe, thus allowing the cold water to flow by said
opening through and into the boiler or heater A, and as the water passes through
the boiler or heater A it becomes rapidly heated. The pressure thus created by the
entrance of the water into the heater or boiler A causes the water to issue at E, and
as heated it passes out at E¹ into the glass or receptacle on table or stand G. When
sufficient is drawn the handle or lever H is turned back and the supply of water to
the boiler or heater A is stopped, the main supply of gas is turned off, leaving only
the pilot light burning. The water in the boiler and in the pipe D is continuously
in circulation, and instead of issuing by outlet E' passes back into the boiler by the
inlet F. The plug of the cock to take off the surplus water, passing through the
table or stand G may be made hollow, through which tho wator escapes. We prefer
however to use a pipo M¹ having communication with the said tablo or stand, as
shown in Fig. 6, through which the surplus water escapes, and is conveyed away
as required. Figs. 4, 5, 6, and 7 represent a modified form of Figs. 1, 2, and 3. The
boiler or heater and cock, although not shown, are used as in Figs. 1, 2, and 3,
instead of having an arched pipe a single tube is employed in which is enclosed a
pipe of the form shown in Fig. 6, so that the water rising in one portion descends
through the other, the action of delivery being that when the table or stand G is
turned, or the lever or handle H, as before described, the water issues by the
outlet E¹, as before described, and when shut off the water flows back to the heater
or boiler.
For heating water for baths, lavatories, and such like purposes (see Figs. 16
and 17) the arrangements are similar to those for heating water, shown in Figs. 1,
2, and 3. In place of the table a lever or handle is used which on being turned to
gas on" allows the full supply of gas to pass through the pipe L which is ignited
by the small pilot light. The gas by this same action is allowed to flow, and when
the handle is further turned the cold water enters, as before described, into the
boiler or heater A, and from the boiler or heater A flows by the pipe R into the
bath or other receptacle. Here we may remark that although our Invention is for
improved heating apparatus yet it may if desired be utilized for cooling water or

page_text: other liquids. Thus when the water or other liquid is to be conveyed and delivered
cooled, a cooling chamber is used instead of the boiler or heater. This chamber is
fitted with a coil, which at one end is in communication with the supply pipe,
governed by the cock or valve. The chamber is filled with ice, powdered or lump,
around the coil, and the water passing through the coil becomes in its passage cooled
and is delivered as cooled in the manner as before described. This chamber is pre-
ferably covered with felt, a perforated bottom on which the ice is placed being
employed so as to allow the water to pass into a chamber beneath. It must of course
be understood that the gas is to be shut off when the cooling arrangement is to
be used.
Having now particularly described and ascertained the nature of the said In-
vention, and in what manner the same is to be performed or carried out in practico,
we would here remark that we do not limit ourselves to the precise details herein
described or delineated, but we claim the Invention of Improved Heating
Apparatus Specially Arranged for Facilitating the Conveying and Delivering of
Heated Water and other Liquids," substantially as hereinbefore set forth and
described, in which Invention the following are important points or features:-
:-
(1.) The combination and arrangements of cock or valve whereby the lever or
handle H attached to table G when partly turned allows of the issue of gas to the
main burners M, and when further turned allows the water or liquid to flow into
the heater or boiler, the gas way still remaining open or gas still passing through,
substantially as herein before described.
(2.) The arrangements for circulation of the water or liquid and the opening for
the flow of heated water at the top or highest point in the arched tube, which
opening provides that the flow of heated water is not interfered with, as would be
the case if the opening was at the bottom or under side of the tube or anywhere
else. These arrangements enable the small independent or pilot jet of gas to
heat the water and circulate it, so that when turned on the water flows out at
the highest part.
In witness whereof, we, the said Samuel Mart and Charles Wallace Bradley,
have hereunto set our hands and seals, this Thirtieth day of August, in
the year of our Lord One thousand eight hundred and seventy nine.
