IMPROVEMENTS IN AND RELATING TO HEATING OR WARMING APPARATUS to be as follows
Year: 1885

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co Patent
Agents, Southampton Buildings, in the County of Middlesex do hereby declare
the nature of my invention for "IMPROVEMENTS IN AND RELATING TO HEATING
OR WARMING APPARATUS to be as follows:-
"
This invention relates to warmers of that class in which heat is accumulated by
melting acetate of soda, resinous matters, or other suitable substances; and has for
its objects to provide means for heating such apparatus by steam and to remove
the condensed water therefrom.
To attain these objects heating pipes are arranged inside the warmers,
which
pipes are surrounded by the substances to be melted and connected at one end
with a suitable steam generator (which in certain cases for apparatus for domestic
use etc, may form a part of the warmer), while the other end communicates with
the air or with a water reservoir, the contents of which are heated by the waste
steam and serve to heat the outer shell of the warmer and to feed the steam
generator.
For removing the condensed water from the heating pipes I make use of a steam
trap, which is composed of a hollow globe which serves as a valve, or may be
connected with a valve in such a manner as to lift the valve from its seat when
the globe is raised by condensed water. As such hollow globe may easily burst
when being heated or contract when being cooled after heating, the valve stem or
shaft consists of a tube communicating with the air, thus expelling and intro-
ducing air from and into the globe when necessary. A suitable reflector may be
provided around the mouth of the tube, whereby the entrance of water into the
globe is prevented.

I WILLIAM ROBERT LAKE, of the firm of Hasletine, Lake & Co Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed; to be par
ticularly described and ascertained in and by the following statement :-
This invention relates to improvements in warmers, in which heat is accumu-
lated by melting acetate. of soda, resinous matters or other suitable substances; and
the objects of these improvements are to provide means for heating such apparatus
by steain and to remove the condensed water therefrom.
To attain these objects heating pipes are arranged inside the warmers, which are
surrounded by the inatters to be melted, and connected at one end with a suitable
steain generator (which in certain cases for apparatus for domestic use etc may
form a part of the warmer), while the other end communicates with the air or with
a water reservoir, the contents of which are heated by the waste steam and serve
to heat the outer shell of the warmer and to feed the steam generator.
For removing the condensed water from the heating pipes I make use of a steam
trap, which is composed of a hollow globe, which serves as a valve or inay be
connected with a valve in such a manner as to lift the valve from its seat when
the globe is raised by condensed water. As such hollow globe may easily burst
when being heated or contract when being cooled after heating, the valve stem or
shaft consists of a tube communicating with the air, thus. expelling and intro-
ducing air from and into the globe when necessary. A suitable reflector may be
provided around the mouth of the tube, whereby the entrance of water into the
globe is prevented.
In order to make the invention more clearly understood I will describe it with
reference to the accompanying drawings.
Figure 1 is the vertical section of a warmer for domestic use, a is the warmer
containing the heating matter, and b is a boiler inserted in the bottom of the said
warmer. This boiler is filled with water and beated by a stove or other suitable
fire place; the steam generated passes through the pipes d d and communicates
heat to the acetate of soda, resin or other material enclosed in the warmer a. c is a
safety valve to prevent explosions.

Figure 2 illustrates.another construction of the warmer. Through the warmer a
passes a bent pipe d, the end d¹ of which may be connected with a steam supply
pipe, while the other end dis provided with a waste-cock e. With the pipe d, is
connected a steam trap, the construction of which is shown on an enlarged scale in
figure 3. The hollow stem f¹ of the valve'f is surrounded at its lower end by a
deflector f; its upper end is provided with the hollow globe f. 'When condensed
water has accumulated around the globe f³, the latter begins to float and thereby
lifts the valve f from its seat f*, thus allowing the water to escape.
deflector prevents the water from entering into the stem f¹. As the globe f³
is in connection with the atmosphere by the hollow stem f¹, the varying tempera-
ture inside the pipe d does not cause any contraction or expansion of the shell of
the globe.
The

page_text: Figures 4, 5 and 6 illustrate the heating process of a series of warmers for
railroad cars etc. The warmers a are placed side by side in an upright position in
a tank g filled with water. The said tank is then brought under the steam pipes h,
which by means of the mouth pieces i permit the introduction of steam into the
bent pipes d in the interior of the warmers a. As the outlet end of each pipe d
discharges into the water of the tank g, such water will be heated too, and thereby
communicate heat to the outside shell of the warmers a. To obtain an air tight
connection between the mouth pieces and the pipes d, the pipes / are pressed
upon the warmers by means of screw and the mouth pieces i may be constructed
in the manner as shown in figure 7. Inside each mouth piece i is a small pipe ¹
screwed or otherwise fastened to the supply-pipe h; the lower end of the pipe ¹ is
surrounded by a disc i³, which, by means of a stuffing box is, slides tightly on the
pipe A spiral spring has the tendency to press the disc downwards
towards the socket-piece or ferrule d' of the pipe d, into which enters partly the
pipe . An india-rubber plate 2, beneath the disc i, fitting closely to the inside
of the mouth piece i, serves to produce an air-tight joint between the latter and
the ferrule d or the end of the pipe d. The nut screwed upon the under end of
the mouth piece serves to hold the disc is and India-rubber ring in their proper
place when the heating apparatus is not in use.
Figure 8 shows the manner of placing the tauk 9 when set upon wheels under
the supply pipes h, m n being stands wherein the pipes h are guided vertically and
pressed downwards by the screws e. The heating steam enters at . For railway
purposes a travelling-platform o may be provided between the stands m and n in
order to transport the tank g with a series of foot warmers from one track to
another and under the treating pipes h. Thus a number of warmers can be heated
simultaneously as the self adjusting mouth pieces will fit closely to the ferrules d¹
of the pipes d notwithstanding any differences in the height of the warners.
But if all the ferrules are at the same level the adjustable mouth piece may be
dispensed with and the fixed mouth pieces as shewn in Figures 4 and 5 may be
used.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent I declare that what I claim is
First. In apparatus for heating purposes, the combination of the warmer, filled
with acetate of soda, resinous matter or other suitable material, with a pipe placed
inside the warmer for heating by steam the matter enclosed within the warmer,
substantially as set forth.
Second. In apparatus for heating purposes, the combination of the pipe d,
serving to heat by steam the matter contained in the warmer a, with the valve f,
the hollow valve stem f¹, the hollow globe få and the deflector f³ substantially as,
and for the purpose, specified.
Third. In apparatus for heating foot warmers provided with inside heating
pipes, the combination of the steam supply pipe with the mouth-piece i, the
small inlet pipe i¹, the spring ³, the disc ³ provided with a stuffing box is and
the packing disc i, substantially as, and for the purpose, specified.
