DAVID CADDICK, Furnace Builder, 7, Hartington Road, Middlesbrough, in the
County of York, and CHARLES OLIVER, Builder, 65, Grange Road East, Middles-
brough, in the County of York, do hereby declare the nature of this invention to
be as follows;-
The improvement consist
1stly. In the shape of the boiler, which is an octagon and may be made either
of copper tinned plates, galvanized wrought iron or cast iron.
2ndly. In the construction of the flues, which are divided by a midfeather, into
front & back flues. The flame from the grate travels up the front flue and over
the midfeather into the back flue, whence it passes down the back of the boiler
into the bottom of an iron pipe.
3rdly. In the pipe, containing valve or slide damper for regulating the heat,
which pipe forms the bottom part of the flue or chimney.
4thly. In the application of composition blocks, for building the flues, these
blocks being made of a composition of old ground fire bricks fire clay and cement
and are less costly and more durable than fire bricks.
5thly. In the steam preventing cover and frame, with lid to open and shut, and
small pipe, leading from the boiler through the frame into the flue or chimney.
The steam is conveyed through the pipe into the chimney whence it passes into
the air outside. The cover & frame are made of wood and joined at the back
by a brass hinge.

Improvements in and relating to Wash Boilers.
DAVID CADDICK, Furnace Builder, Victoria Road East (late of 7; Hartington
Road), Middlesbrough, and CHARLES OLIVER, Builder, 65, Grange Road. East,
Middlesbrough, in the County of York, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention consists of an improved wash boiler for domestic purposes as
per drawing herewith. The boiler, marked a, is octagon or square in shape and
may be made of copper, tinned plates or cast iron. The flues, c c, are divided

page_text: by a midfeather, B, into front and back flues. The flame from the grate rises
up the front flue, passes over the midfeather into the back flue and thence to
the chimney. The midfeather serves to keep the flame in contact with the boiler
for a longer period than it could be kept without the midfeather and the latter
is also a means of preventing the flame getting away too soon, as is the case with
ordinary flues. On the top of the boiler is a wood frame and cover, d. The frame
is perforated with a number of holes. The steam from the boiler passes through
these holes into the steam pipe or flue d, thence into the chimney by which
it is conveyed into the outer air. By these means no steam escapes into the wash-
house, which is kept entirely free from steam and moisture.
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: -
1st. The shape of the boiler a, which is octagon or square and may be made of
copper, tinned plates or cast iron.
2. The construction of the flues cc and consequent economy in fuel.
3. The steam preventing cover and frame d and steam pipe or flue, d leading
into the chimney d.
