Improvements in Apparatus for Automatically Controlling the
Temperature of Fluids.
We, FREDERICK LAMPLOUGH, Engineer, Glen Ridge, New Jersey, United States of
America and THE AUTOMATIC HEAT REGULATOR COMPANY, LIMITED, Broad Street
Avenue, Blomfield Street, London, 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:-
Our improvements are more particularly applicable to the apparatus described in
the Letters Patent No. 8199/95 already granted to F. Lamplough and entitled
Apparatus for automatically controlling the temperature of fluids."
<<
In order that our invention may be more readily understood we have attached
hereto two sheets of drawings in which similar letters refer to similar parts.
Fig. 1. represents a high pressure gas burning apparatus preferably used in
connection with a suitable gas stove or stand S as shown in Fig. 4.
Fig. 2. represents a high pressure gas burning apparatus which may be fixed in or
to the bottom of the vessel or container containing a liquid, the temperature of
which is to be regulated.
Fig. 3. represents a low pressure or atinospheric gas burning apparatus which may
be fixed to the bottom of a vessel or container.
In applying the apparatus to a vessel or container containing a liquid, the
temperature of which is to be regulated, we preferably solder in the bottom of the
said vessel or container A, Figs. 2 & 3 a suitable pocket B projecting into
the liquid. Into this pocket B is screwed or otherwise fixed the burner casing C and
controlling mechanism. The pocket may be made to receive different forms of
burner as Figs. 2 & 3, without being detached from the container. A screwed
ring B¹ is preferably soldered in the said pocket to suit the screwed end of the
casing C as shown.
The expansion chamber D is preferably arranged loose to rest on the spindle E of
the controlling valve J; and is pressed against the top of the pocket by a suitable
spring F. The body or casing C of the apparatus may be formed into an atmospheric
burner as at G; or into a high pressure burner, or separate high pressure jets H may
be attached to the said casing as desired. The expansion chamber D with the
controlling valve J will be supported in the body C in such manner that the said
chamber projects above the top of the body thus ensuring contact with the pocket
as before described.
The seat K of the controlling valve may be formed on the top of the gas inlet
pipe L which enters the lower part of the body as Fig. 2 or the seat K may be made
separate and then attached to the gas inlet pipe L as Figs. 1, 3 & 4 by a screw or by
spinning the metal over the flange of the valve seat.
The seat K can be adjusted to the valve by means of a screw and locknut M on
the pipe L. The inlet pipe L will preferably be provided with a packed gas tight
plug joint N, so that it may revolve in the end of the service pipe P, for
adjusting; or may slide out when the vessel is removed. Any other suitable form
of joint may be used for the same purpose.

page_text: In Figs. 1, 2 & 4 the end of the inlet pipe L is formed into a packed plug N
working in a socket attached to the gas inain P as before described.
In Fig. 3 the end of the pipe L forms a socket 0 in which slides a packed plug N¹
fixed to the service pipe, or gas main P.
The atmospheric burners shown in Figs. 3 & 4 will be preferably provided with a
gas and air mixer R formed as shown.
In applying the apparatus to a gas stove or stand S Fig. 4 a special elbow fitting T
will be arranged for fixing in the lower part of the said stove. This elbow T will be
provided with a socket O in which slides the plug N on end of burner as previously
described.
The lower end of the inlet connection N will be provided with a gas inlet valve U
resting on the bottom of the elbow T. The valve face V will be about midway up the
valve and the seating W will be the piece X screwed into the end of the inlet
connection. A spring Y between the top of this valve U & a bridge Z screwed into
the inlet connection N will be made to raise the body C together with the burner &
expansion chamber D above the top of the stove S so that when a vessel is placed on
the said stove, it will depress the body of the apparatus and lower the seat from the
valve. A bye pass or leakage round the valve, U will be arranged to allow sufficient.
gas to leak through said valve to keep said burner alight, when the apparatus is
raised to its normal position.
In this form of apparatus Figs. 1 & 4 we prefer to make the top disc. D¹ of the
expansion chamber D-rigid while the lower disc D2 will be flexible for operating the
controlling valve J as previously described.
The before mentioned elbow fitting T may be replaced by a straight fitting having
a suitable bridge for receiving the valve stem U.
In Fig. 1 is shown a high pressure gas burning apparatus for use in connection.
with the gas stove in Fig. 4. This apparatus is similar to that herein before
described for Fig. 4 with the exception of the jets H and the controlling arrangement,
which are similar to those herein before described, for Fig. 2.
With reference to the gas stove in Fig. 4 it will be understood that the weight
of the vessel to be heated will depress the body of the apparatus and so open the
inlet valve U wide, but as soon as the predetermined temperature of the vessel is
reached, the expansion chamber D & the controlling, valve J will come into action,
as described with reference to the Letters Patent hereinbefore mentioned.
In Figs. 3 & 4 the controlling valve J slides in the seating K and is made
sufficiently smaller than the seating to allow a leakage for keeping the gas flame
alight when the apparatus has acted to its fullest extent, so that the flame cannot be
put entirely out.
In Fig. 3 the bridge piece F1 carrying the spring F will be fixed in the part F2 by
spinning the metal over in the usual way, also the diaphragm in the mixer R. Fig. 3
and the nut C¹, Fig. 2 will be fixed in a similar manner.
In Fig. 3 the locknut M is made in the form of a bell to protect the air inlet holes
in piece L.
Having now particularly, described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In apparatus for controlling. temperatures. the use of the pocket piece B, as
and for the purposes herein described, with, reference to Figs. 2 & 3.
2. In apparatus for controlling temperatures the spring, F for maintaining the
expansion chamber D in contact with the pocket piece B. as & for the purposes
herein described with reference to Figs. 2 & 3.
3. In apparatus for controlling, temperatures the method of adjusting the
valve seat by means of a screwed inlet pipe L. with lock nut M as & for the
purposes herein described with reference to all figs.
4. In apparatus for controlling temperatures the plug joints formed by the

page_text: parts N, O, or N¹, O¹ as and for the purposes herein described with reference to all
figures.
5. In apparatus for controlling temperatures the form of atmospheric burner G, as
and for the purposes herein described with reference to Figs. 3 & 4.
6. In apparatus for controlling temperatures the gas inlet valve U spring Y,
seating W and bridge piece X as for the purposes herein described with reference to
Figs. 1 & 4.
7. In apparatus for controlling temperatures an expansion chamber D having one
rigid side and one expansible side as and for the purposes herein described with
reference to Figs. 1 & 4.
8. In apparatus for controlling temperatures the combination of the various parts
to form any or all of the complete apparatus as and for the purposes herein
described with reference to all figures.
