PROVISIONAL SPECIFICATION.
Improvements in Mash Tuns or Substitutes therefor.
I, LOUIS VAN DEN HULLE of 41 Rue de Bruges Ghent in the Kingdom of
Belgium, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the improved mash tun or substitute therefor described
in the Specification of Letters Patent No. 23244 dated 16th December 1892 and
more particularly to the agitator used therein.
When it is desired to make this agitator removable, the arms are made fixed to
the shaft, which latter is made removable. For this purpose its ends.are held in
U shaped socket bearings one at each end of the cylinder or vessel so that it may
be simply lifted out when desired. The upper part of the vessel is so shaped, that
is to say with vertical or parallel walls, that the agitator may have space to pass
when lifted out.
The agitator is operated from a parallel arhor carrying a spur wheel which
meshes with a spur wheel on the agitator shaft. This arbor traverses the wall of
the vessel and carries outside the latter the pulleys or devices for rotating it. It
may also be moved endways in its bearing to enable the spur wheels to be brought
in or out of gear with each other.

COMPLETE SPECIFICATION.
Improvements in Mash Tuns or Substitutes therefor.
I. LOUIS VAN DEN HULLE, of 41 Rue de Bruges Ghent, in the Kingdom of
Belgium, 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 the improved mash tun or substitute therefor described
in the Specification of Letters Patent No. 23244 dated 16 December 1892 and more
particularly to the agitator used therein.
When it is desired to make this agitator removable the arms are made fixed to
the shaft N, which latter is made removable. For this purpose its ends are slid
into and held in U-shaped socket bearings A (Fig. 1, Fig. 14, Fig. 2) one at each
end of the cylinder or vessel so that it may be simply lifted out when desired.
upper part of the vessel is so shaped, that is to say, with vertical or parallel walls,
that the agitator may have space to pass when lifted out.
The
The agitator shaft N is operated from a parallel arbor carrying a spur wheel C
which meshes with a spur wheel B on the agitator shaft N. This arbor passes
through a busbing C' in the wall of the vessel and carries outside the latter the
pulleys D or devices for rotating it. It is rotated in such direction that the
pressure exercised by the spur wheel C on the teeth of the spur wheel B is in
a downward direction, so that this force added to the weight of the agitator will
prevent the agitator from rising when in action. This arbor may also be moved

page_text: endways in its bearing C₁ to enable the spur-wheels to be brought in or out of gear
with each other.
A force of from 10 to 20 lbs. will be sufficient to cause this movement of the arbor.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improvements in the mash tuns or substitutes therefor hereinbefore referred
to consisting in :-
1. The construction for permitting removal of the agitator shaft.
2. The means for revolving the agitator and permitting the disengagement of
the driving shaft or arbor therefrom. Both substantially as herein described and
illustrated.
