Improvements in and connected with Machines for Drying Fish Offal,
Stable, Town, and Slaughterhouse Refuse and other Materials and
Substances requiring similar Treatment.
I, HENRY WINCKLER, of 110, Cannon Street, in the City of London, Merchant,
do hereby declare the nature of this invention to be as follows.
This invention relates to improvements in and connected with machines for
drying fish offal, stable town and slaughterhouse refuse, refuse from manu-
facturies and the like and other materials or substances requiring similar treat-
Eent, for instance grain rice chemicals and so on, whereby the said material is
dried by hot air generated in a furnace.
The object of my invention is to pass the hot air into the material in the
machine in such a way that they become thoroughly mixed and the drying pro-
perties of the hot air are made use of in the most thorough and economical man-
ner.
For the generation of hot air I build into the furnace immediately underneath
the roof or arch of the same a canal or pipe or series of canals or pipes so that
the same are continually surrounded by the flames. These canals or pipes may
pass once straight through the furnace or bend backward and forward or they
may be in the form of coil or in any other form, as most convenient for the
purpose and as to whether a more or less intense heat or large quantity of air is
required. At one end the canal or pipe or

These pipes inside the machine are perforated and the heated air passing out of
these perforations is brought into immediate contact and thoroughly mixed with

a series of arms and beaters is provided..

made in such a manner that such material is continually moved in one direction,

Improvements in and connected with Machines for Drying Fish Offal,
Stable, Town, and Slaughterhouse Refuse and other Materials and
Substances requiring similar Treatment.
I, HENRY WINCKLER, of 110, Cannon Street, in the City of London, 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 improvements in and connected with machines for
drying fish offal, stable town and slaughterhouse refuse, refuse from manu-
facturies and the like, for instance grain rice chemicals and, other materials and
substances requiring similar treatment wherein the said material is dried by
hot air generated in a furnace and continuing flue.
The object of my invention is to pass the hot air into the material in such a
way that both become thoroughly mixed and the drying properties of the hot
air are made use of in the most thorough and economical manner.
For the generation of hot air I build into the furnace immediately underneath
the roof or arch of the same a canal or pipe or series of canals or pipes so that
the same are continuously surrounded by the flames and combustion gases. These
canals or pipes may pass once straight through the furnace or bend backward
and forward or they may be in any other form as most convenient for the
pose and as to whether a more or less intense heat or a larger quantity of air is
required. The pipes also continue in the flue. For the purpose of protection
from the effects of the direct fire the pipes may be surrounded by fire brick
material or covered or embedded in fire clay, asbestos or other like materials..
pur-
At one end the canal or pipe or canals or pipes are connected with an air
pump, compressor, fan or blower and by this means the air is injected in such
quantities as best suited for the material to be dried. The other end of the
canal or pipe is connected to pipes leading into the drying machine. The latten a
pipes either enter the machine at the bottom or they may be continued inside the
machine on the bottom of the same.
air by passing through the canal or pipe in the furnace and flue becomes heated
In the latter case they are perforated. The
and entering the machine passes immediately into and through the material to
be dried.
The machine is built preferentially in the form of a drum or cylinder standing
over the furnace and flue and a turning arrangement consisting of a number of
arms and beaters is provided inside for the purpose of stirring the material.

Where the material to be dried allows it, the turning arrangement may be
made in such a manner that the material is continually moved in one direction, 4
so that by providing an inlet or hopper at one end and an outlet at the other end
the machine becomes a continuous dryer.
The outside of the machine is, bricked in, either the whole or part of it in such
a way that a space is formed between the brick work and the sides of the machine
and through this space the combustion gases of the same furnace and rising 5

machine is thoroughly heated from the outside.
If desired and where the material allows it the combustion gases can also be
passed into the machine to still more accelerate the drying.
In addition an exhauster can be provided to draw off quicker the evaporated
moisture.

pipe or canal from the compresser, b, is the hopper of the machine F; c, the
outlet, d, the exhaust and e, the beaters.
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:-
1. An improvement in and in connection with drying machines by passing
hot air generated inside a pipe or pipes fixed in a furnace and continuing flue
and being connected with pipes leading into the bottom of the machine, the
air being forced in by means of an air compressor, the gases of the same furnace
at the same time heating the outside of the machine substantially as herein before
described and illustrated by the drawings.
