PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating, Evaporating and Condensing,
applicable for Heating Feed Water, Generating Steam, Condensing
Exhaust in Steam Engines, or other Purposes.
I, EDWARD MAKIN, Junior, of 40, New Brown Street, Manchester, in the
County of Lancaster, Cotton Manufacturer, do hereby declare the nature of this
invention to be as follows:
-
This invention relates to apparatus for heating feed water, or for generating,
or superheating or condensing steam and consists in improvements upon and
modified applications of the kind of apparatus described in my Specifi-
cation 17358 A.D. 1896.
My improvment consists chiefly in forming the jacketed or hollow cones
described in my said specification of coiled piping or tubing. I form said conical
coils of steel or other metal tubing, made by lapping the same round a conical
mandrel or a series of conical mandrels placed the one behind the other.
Each coiled cone may be formed separately and connected to another cone or
to pipes or chambers by couplings or other ordinary means, according to the
use to which the cones are to be put. Or sey ral such cones may be formed out of
one length of pipe. This arrangement is pr erable when the conical coils are used
for instantaneous steam generation, the multiple conical coils being placed
preferably vertically inside flues or chambers and heated in any convenient way,
and the water inlet and steam outlet pipes connected to the bottom and top coil
respectively. By this arrangement of multiple coils a large heating or efficient
steam generating or super heating surface is obtained. Several of such multiple
coiled cones may be used connected at the bottom to a common water supply and
at the top to a common steam pipe or chest.

I, EDWARD MAKIN, Junior, of 40, New Brown Street, Manchester, in the
County of Lancaster, Cotton Manufacturer, 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 apparatus for heating feed water, or for generating,
or superheating or condensing steam and consists in improvements upon and
modified applications of the kind of apparatus described in my Specifi-
cation 17358 A.D. 1896.
My, improvement consists chiefly in forming the jacketed or hollow cones or
arrangement of cones described in my said specification of coiled piping or
tubing. I form each cone as a conical coil of steel or other metal tubing. The
coils are made by lapping the tubing round a conical mandrel or round a series
of suitable conical mandrels placed the one behind the other.
Each coiled cone may be formed separately and connected to another cone or
to pipes or chambers by couplings or other ordinary means, according to the
use for which the cones are to be put. Or, several such cones may be formed out of
one length of pipe. This arrangement is preferable when the conical coils are used
for instantaneous steam generation, the multiple conical coils being placed
preferably vertically inside flues or chambers and heated in any convenient way,
and the water inlet and steam outlet pipes connected to the bottom and top coil
respectively. By this arrangement of multiple coils a large heating or efficient
steam generating or superheating surface is obtained. Several of such multiple
coiled cones may be used connected at the bottom to a common water supply and
at the top to a common steam nipe or chest.
For surface condensers, or for feed water heaters, I preferably use a series of said
multiple coiled cones placed vertically and connected at the top to
a common steam chamber, and at the bottom to a common exhaust
chamber with a suitable discharge pipe. With this arrangement of
condenser, air may be used as the cooling medium as the condensing surface
presented by the coiled cones is very large, and their shape and arrangement above
each other promotes the circulation of air. The same arrangement however may
also be used for water cooled condensers with the water circulating through
the coiled cones, or surrounding them, and for evaporative condensers.
After the conical coils have been formed, they may have aluminium, cast iron
or other metals or alloys, cast upon them on the outside or on the inside or both,
of the cones to protect them against the action of the flames, thus forming solid
cones with a coiled core, or a coiled core with metal cast on the outside or on the
inside only.
The drawings attached hereunto illustrate the construction of single and
multiple cones made in accordance with my invention and some applications of
the same. Figure 1 represents a couple of cones arranged as described in my said
Specification, 17358, A.D. 1896 and formed in accordance with this invention.
Figure 2 represents several series of cones likewise formed and connected to
feed and discharge chambers and suitable for surface condensers, or feed water
heaters. Figures 3 and 4 represent two sectional elevations of single cones
shewing in what manner they may be jacketed.
Referring to Figure 1 each cone of the series is made separately as herein-
before described and has the ends of the pipe forming the cone connected to two

page_text: main pipes 6 and 6, the ends a¹ of the larger coil being connected to the
pipe and the ends a² of the smaller coils being connected to the pipe b¹.
Referring now to Figure 2 which represents a surface condenser, each series c
of cones is illustrated as made from a continuous piece of tubing, one end c¹ of
which acts as an inlet and the other end as an outlet, the ends being connected
to separate boxes or pipes d . The enclosed space e between the boxes d d'
having inlet and outlet g pipes serves for the circulation of cold water or air.
A similar arrangement of coiled cones and chambers can be used for heating
feed water by means of exhaust steam, the water circulating either through the
coils and the steam passing through the chamber surrounding them or vice versa.
Figures 3 and 4 represent in vertical section two cones made from coiled tubing
and enclosed or jacketed by suitable cast metal.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
Firstly: The improvement in the invention described and claimed in the
Specification for my Patent No. 17358 A.D. 1896 which improvement consists
in forming the hollow walled vessels of coiled tubing without or with a jacket
of cast metal substantially as hereinbefore described and illustrated by the
drawings.
Secondly: In apparatus for heating feed water, evaporating water, generating
steam or condensing exhaust steam and like purposes the use and arrangement
of a series of hollow walled frustrums of cones arranged with the longitudinal
axis of each coincident, and with the smaller end of one cone opposite the larger
end of the next cone, each cone being formed as a coil from suitable metal tubing
through which the water or steam circulates, substantially as hereinbefore
described and illustrated by the drawings.
Thirdly: The formation of a series of water or steam circulating cones as
claimed in the preceding claim of one continuous length of tubing, substantially
as herein before described and illustrated by the drawings.
Fourthly: The construction and use of a series of frustrums of cones, arranged
as hereinbefore described, of suitable metal tubing coiled, and jacketed by
suitable cast metal, substantially as and for the purpose set forth and as illustrated
with reference to Figures 3 and 4 of the drawings.
