PROVISIONAL SPECIFICATION.
Improvements in or relating to Apparatus for Drying Brewers'
Refuse, Grains, and the like.
I, EDWARD MAKIN Junior, of 40 New Brown Street, Manchester, in the
County of Lancaster, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
:-
My invention relates to improvements in the invention for which Letters Patent
numbered 18833 were granted to Edward Barlow on the 31st October 1891.
My present improvements consist chiefly in improved arrangements for feeding
and discharging the brewers' refuse, grains or other substances and an improved
internal construction of the drying cylinder or druin and mode of travelling the
refuse substances through the same whilst being dried.
In carrying my improvements into effect I supply hot air heated by any suitable
means to the rotating drum through one of the trunnions or journals of the drum.
In communication with the hot air supply pipe I place a hopper or other suitable
feed apparatus by which the refuse substances are fed preferably automatically

connected to an exhaust fan which is driven at a high speed and draws the refuse

the rotation of the drum.
To promote a free current and circulation of hot air the baffle plates are

which will allow air to flow freely through it but will not permit any considerable
quantity of the refuse substances to pass through.
The refuse substances such as spent hops admitted in a saturated condition
through the hot air inlet are drawn slowly through the winding passage in the
rotating drum and are finally discharged dry or comparatively dry through the
outlet trunnion by the exhaust fan in one continuous and practically automatic
process.
If necessary the dried or comparatively dry substances are discharged by the
fan on to a hot floor or heated plates or the like to complete the drying process.

Refuse, Grains, and the like.
I, EDWARD MAKIN Junior, of 40 New Brown Street, Manchester, in the
County of Lancaster, 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 :-
My invention relates to improvements in the invention for which Letters Patent
numbered 18833 were granted to Edward Barlow on the 31st October 1891.
My present improvements consist chiefly in improved arrangements for feeding
and discharging the brewers' refuse, grains or other substances and an improved
internal construction of the drying cylinder or drum and mode of travelling the
refuse substances through the same whilst being dried.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a side elevation and Fig. 2 a plan of my improved apparatus for
drying brewers' refuse and the like, and
Fig. 3 is a cross section of the drum.
The drum a is supported at one end on a pair of rollers 6 mounted in a stand c,
and at the other end the trunnion a' of the drum is supported in a bearing d. On
the trunnion a' is secured a worm wheel e which is driven by means of a worm on
a shaft which receives motion from a belt, not shown, and a pair of fast and loose
pulleys To the other trunnion of the rotating drum a is connected a pipe g
through which according to my improvements I supply hot air heated by any
suitable means to the interior of the drum. In communication with the hot air
supply pipe g by means of a cross pipe I place a hopper h¹ and screw conveyor
or other suitable feed apparatus by which the refuse substances are fed automati-
cally through the hot air inlet into the rotating drum. The interior of the drum a
is fitted with a series of baffle plates j as indicated or a worm or similar device
which will form a continuous but a winding or indirect passage for the refuse
substances from the inlet trunnion to the outlet through the opposite trunnion a¹.
The outlet trunnion a' is connected to an exhaust fan k which is driven by a belt,
not shown, and pulley kat a high speed and draws the refuse substances and hot
air admitted through the inlet through the winding passage in the drum a, the
drawing through process of the refuse substances being assisted by the rotation of
the drum.
To promote a free current and circulation of hot air the baffle plates j are
preferably made of wire gauze or perforated sheet metal or other suitable material
such as the lattice work shown in Fig. 3, which will allow air to flow freely through
it but will not permit any considerable quantity of the refuse substances to pass
through.
The refuse substances such as spent hops admitted in a saturated condition
through the hot air inlet are drawn slowly through the winding passage in the
rotating drum and are finally discharged dry or comparatively dry through the
outlet trunnion by the exhaust fan k in one continuous and practically automatic
process.
If necessary the dried or comparatively dry substances are discharged by the
fan on to a hot floor or heated plates or the like to complete the drying process.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The general combination and arrangement of parts embodying my improvements
in or relating to apparatus for drying brewers' refuse, grains and the like
substantially as herein described with reference to the accompanying drawings.
Dated this 17th day of February 1896.
