IMPROVEMENTS IN THE CONSTRUCTION OF STEAM GENERATORS ALSO APPLICABLE TO SURFACE CONDENSERS
Year: 1884

page_text: I, WILLIAM SEDDON SUTHERLAND, of Richmond House, Poplar Avenue, Sandon
Road, Birmingham, in the county of Warwick, Engineer, do hereby declare the
nature of my said invention for IMPROVEMENTS IN THE CONSTRUCTION OF STEAM
GENERATORS ALSO APPLICABLE TO SURFACE CONDENSERS to be as follows:-
The object is to construct in an improved manner steam generators and surface
condensers so as to obtain with facility great heating and cooling surfaces with
small water or fluid space and thin though sufficiently strong envelopes.
My invention consists essentially in constructing a steam generator or condenser
by the electro-deposition of, a suitable metal such as copper or silver preferably
copper upon comparatively easily fusible material formed into the desired shape.
When the electro deposition is complete the generator or condenser is exposed to
heat and the fusible mould is melted out after which the said generators and
condensers are annealed in order to render the metal of which they are composed
tough and reliable. Generators so constructed consist of a number of tubes or
spaces of small sectional area exposing a large surface to heat and cold and able to
resist very high internal pressure.

Road Birmingham in the County of Warwick Engineer do hereby declare the
nature of the said invention of IMPROVEMENTS IN THE CONSTRUCTION OF STEAM
GENERATORS ALSO APPLICABLE TO SURFACE CONDENSERS and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:―
The object is to construct in an improved manner steam generators and surface
condensers so as to obtain with facility great heating and cooling surfaces with
small water or fluid space and thin though sufficiently strong envelopes.
My invention consists essentially in constructing a steam generator or condenser
by the electro-deposition of a suitable metal such as copper or silver preferably
copper upon comparatively easily fusible material formed into the desired shape.
When the electro deposition is complete the generator or condenser is exposed to
heat, and the fusible mould is melted out after which the said generators and
condensers are annealed in order to render the metal of which they are composed
tough and reliable. Generators so constructed consist of a number of tubes or
spaces of small sectional area exposing a large surface to heat and cold, and able to
resist very high internal pressure.
The drawing hereunto annexed shows a form of generator advantageous con-
'structed on one piece in accordance with my invention a. are the water spaces of
small sectional area b. deposited metal c spaces for heated gases and products
of combustion.. Instead of making the spaces for water as shown they may be
tubular and the heated gases and products of combustion may play around the
said tubes. Condensers may also be constructed in a similar manner-in this case
water is on one side and steam on the other side of the deposited 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
Constructing steam generators and condensers by the electo deposition of meta!
on a fusible core.
