Improvements in Thermo Electric Generators.
I, HARRY BARRINGER Cox, of 199 Collins Street, in the City of Hartford,
Hartford County, State of Connecticut, United States of America, Electrician,
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:-
This invention relates to certain improvements in the manufacture and con-
struction of thermo electric generators.
The invention consists in certain novel features of construction, and in com-
binations of parts more fully described hereinafter and particularly pointed out
in the claims, and the invention further consists in certain improvements in the
manufacture of thermo electric generators.
Referring to the accompanying drawings
Figure 1 is a vertical sectional view of the completed apparatus.
Figure 2 is a detail sectional view.
The pile is built up of a series of rings or sections a. Each section is composed
of a series of thermo couples connected together in any suitable manner as will
be readily understood by those skilled in the art. The various sections are
suitably electrically connected to include the entire pile in the circuit, and
bb, indicate the binding posts connected, respectively, preferably, by insulated
wires b' with opposite poles of the pile.
In carrying out the present invention a pile is formed of the sections of couples
separated by suitable insulating material c. The sections are suitably held
together and the outer and inner faces thereof are coated with cement or fire clay
or other suitable plastic refractory material d, and baked hard. The pile is then
like a hard stone structure or cylinder. The ends and outer face of the cylinder
are then preferably smoothed off and treated with some suitable substance, such as
plumbago, and the open ends thereof are temporarily closed and the exterior and
ends of the same are coated with a metal jacket e, by electro plating. The metal
jacket e, is preferably confined to the exterior and ends of the pile, but if desirable
the entire pile or structure can be coated with metal. While electro plating at
present appears to be a practical way of providing the metal jacket, still it is
obvious that a thin sheet metal jacket might be wrapped around the outer wall
of the cylinder and suitably secured, and the edges soldered, brazed, or otherwise
fastened and the ends headed over. If a very close fit is desired the metal jacket
can be placed on while the cement or clay is yet soft.
To render the cement or refractory coating impervious to moisture it can be
coated with wax or suitable varnish. ff' indicate the flanged end heads between
which and the ends of the pile, the packing gaskets or rings g, are clamped.
The fire pot h, at its lower end of the pile fits the flange of the lower end
piece, and is preferably provided with supports or standards. The upper end of
the pile is provided with the hood i, mounted on the upper end piece fl. The
outer jacket j, forms a water space around the pile and is fitted in and clamped
between the end pieces f', and the two end pieces and outer jacket are clamped
in position by the bolts k, passing through the end pieces and water space,
whereby all the parts are clamped together.

page_text: It is evident that various changes might be resorted to in the form, construction
and arrangement of the parts described without departing from the spirit and
scope of my invention, hence I do not wish to limit myself to the precise
construction here disclosed.
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 :-
:―
1st. A thermo electric pile coated internally and externally with fire proof
material such as baked clay or cement, as and for the purpose set forth.
2nd. The herein described mode of constructing thermo electric generators
which consists in connecting and arranging the thermo couples to form the pile,
coating the same with fire proof material, such us cement or clay, and then
bardening or baking the same, substantially as described.
3rd. The thermo electric pile having the water jacket surrounding the same so
that the inner wall of the jacket is formed by the outer surface of the pile,
substantially as described.
4th. A thermo electric generator comprising the open pile arranged to be
interiorly heated, the outer face thereof being coated with hardened cement, clay
or the like, and a water space surrounding the same, substantially as described.
5th. The thermo electric generator having the open pile arranged to be
interiorly heated having its outer surface coated with cement, clay or other
protective substance and provided with a metallic jacket, and the water space
surrounding the same, substantially as described.
6th. In a thermo electric generator, the open pile coated externally and
interiorly with hardened refractory material and provided with an external
metallic jacket, substantially as described.
7th. In combination, a thermo pile coated with hardened fire proof material, as
clay or other substance, an exterior metal jacket extending over the ends thereof,
a water jacket around the pile, end pieces, packing between the end pieces and
ends of the pile, and means for holding the end pieces together, substantially as
described.
8th. In a thermo electric generator, the pile having a non conducting coating of
cement, clay or the like, provided with a metallic coating from which the electric
connections of the pile are insulated, substantially as described.
9th. A thermo electric pile having the exterior metal jacket, substantially as
described.
10th. A thermo electric pile having the open interior, and the metal jacket
forming its outer wall.
11th. The herein described thermo electric generator, substantially as described.
12th. The mode of making thermo generators which consists in coating the pile
with refractory material and placing a metal jacket around the same, substantially
as described.
