Improvements in Apparatus for Collecting and Damping Dust
Arising from Cleaning Malt and other Grain.
I, RICHARD HOWARD LEAKER, of Montague Villa, Kingsdown Parade, in the
City and County of Bristol, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its objects to collect and damp the dust arising from malt
and other grain in the process of cleaning the same prior to using the said grain for
brewing, malting and other purposes.
According to this invention the dust, which is separated from the grain in any
well-known manner, is directed by a fan or like appliance into a tube by which it
is conducted into a covered conical chamber the smaller end of which is at the
bottom where there is a suitable outlet preferably controlled by a valve or door.
At the top, that is to say in the cover, is an escape or relief valve or outlet.
As the dust enters the chamber it is deflected downwards by a suitable curved
pipe situated within a box which is surmounted by a blowing or injecting appliance
acting downwardly in which is a steam jet which impinges on the dust and damps
it, a process which is assisted by the addition of a water jet or spray.
The dust thus collected and damped is precipitated in the conical chamber and
is withdrawn or discharged at the foot thereof.

Improvements in Apparatus for Collecting and Damping Dust
Arising from Cleaning Malt and other Grain.
I, RICHARD HOWARD LEAKER, of Montague Villa, Kingsdown Parade, in the
City and County of Bristol, Engineer, 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 has for its objects to collect and damp the dust arising from malt
and other grain in the process of cleaning the same prior to using the said grain for
brewing, malting and other purposes.
According to this invention the dust, which is separated from the grain in any
well-known manner, is directed by a fan or like appliance into a tube by which
it is conducted into a covered conical chamber the smaller end of which is at
the bottom where there is a suitable outlet preferably controlled by a valve or
door.
At the top, that is to say in the cover, is an escape or relief valve or outlet.
As the dust enters the chamber it is deflected downwards by a suitable curved
pipe situated within a box which is surmounted by a blowing or injecting
appliance acting downwardly in which is a steam jet which impinges on the
dust and damps it, a process which is assisted by the addition of a water jet
or spray.
The dust thus collected and damped is precipitated in the conical chamber and
is withdrawn or discharged, at the foot thereof.
In the accompanying sheet of drawings,
Fig. 1 is a side elevation, Fig. 2 a front view and Fig. 3 a plan of my improved

page_text: apparatus for collecting and damping dust arising from cleaning malt and other
grain.
Extended through the wall A, Figs. 1 and 3, of a building containing malt or
other grain is a pipe a through which is directed, by means of a fan or other
suction appliance, the dust separated from the grain. At its outer or delivery end
the pipe a is turned downwards to communicate with the chamber b suitably
secured to the wall A. This chamber bis narrowed down towards the lower end
and communicates with a pipe c by which the dust is led to the receptacle d or
otherwise discharged. A valve or damper e controls communication between the
pipe c and dust chamber b.
On the upper part of the chamber is a relief outlet ƒ for the blast.
The dust on entering the chamber b, is damped by a steam jet admitted to the
throat g through the pipe h, and by a water jet injected through the pipe i. The
dust thus collected and damped is precipitated through the pipe c to the receptacle d,
or is conducted away by a continuation of the pipe c.
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
Apparatus for collecting and damping dust, arising from the process of cleaning
malt or other grain, consisting of the chamber b, with dust and blast inlet
pipe a, outlet pipe c, blast relief outlet f, and the throat with steam inlet h
and water inlet, all constructed, arranged and operating substantially as herein-
before described.
