ALEXANDER SPECHT, of the Firm of Specht, Ziese, and Company, Civil Engineers
and Patent Agents, of Hamburg, Germany. "IMPROVEMENTS IN WASH BOILERS
OR KIERS." [A communication from Theodor Hasbeck and Augustus Hasperg, of
Elmskorn, in the Kingdom of Prussia.]
This Invention relates to the construction of the inner arrangement in wash
boilers, the central circulation pipe of which carries at one or more suitable distances
annular shoulders with radial openings.
On these shoulders rest one or more perforated partitions, moveable on the
circulation pipe, which divide the space for the washing in two or more divisions,
in order to produce a more effective circulation of water through the circulation
pipe and the washing surrounding the same.
The boiler is adapted with a cover of any suitable construction. The inner
arrangement consists of the circulation pipe, having at its upper end and midways
a number of small openings.
The circulation pipe is adapted with one or more series of annular shoulders or
discs with small openings between them. These shoulders carry perforated partitions;
the bottom partition rests on brackets fixed to the boiler.
The working of this apparatus is as follows:-First, one part of the washing is
put on the lowest partition, then the next partition is adjusted and filled with
washing, and so on. As soon as the washing is filled into the boiler, water is poured
in and the cover has to be firmly fastened. During the boiling of the water, water
or steam enters the circulation pipe and flows out from the top opening as well as
from the intermediate openings, and penetrates through the washing extending over
the wash boiler. After passing through the washing, the water drops down through
the perforation in the partitions until it arrives at the bottom of the boiler, from
where the same circulation takes place. The water or steam is forced to enter
into the circulation pipe by means of a funnel extending over the bottom of the
boiler.

page_text: The core inside the circulation pipe, which increases in diameter from bottom to
top, serves to replace the open space which would remain between the water and
steam, ascending by means of the heat in the circulation pipe; so by arranging the
core of the circulation pipe tapered the circulation of water in the pipe gets more
rapid.
The arrangement of dividing the space for the washing in several partitions
allows a more effective and equal penetration of water and steam through the
washing than in all other wash boilers hitherto known.
All wash boilers now in use have the great disadvantages, firstly, that the washing
is liable to cover the small openings in the circulation pipe, and so prevents an
effectual penetration of water through the washing; and, secondly, that the washing
is easily torn in pieces by the short outlets extending sideways from the circulation
pipe.
In the present Invention the side openings of the circulation pipe are so
arranged that they can never be covered by the washing, and no sharp edges or
corners are connected with the circulation pipe, which is a great advantage over all
wash boilers at present in use.
