PROVISIONAL SPECIFICATION.
An Improved Cask Tilter.
I, CHARLES DAVIES Plumber 25 Marsden Square Manchester do hereby
declare the nature of this invention to be as follows:-
The improved cask tilter is operated by compressed air, and water, oil, or other
liquids, or by water under pressure, as from a towns main, or solely by compressed
air, or other gases, the principle being the admission through a small aperture
under the piston, in an inner chamber of the air, or liquid, contained under pressure,
in an outer chamber or jacket, so that the piston, is raised with any degree of speed,
as the liquor is emptyed from the cask, that may be found suitable for raising the
cask without muddling the contents.

I, CHARLES DAVIES Plumber 25 Marsden Square Manchester 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 :-
The improved cask tilter is operated by compressed air and water, oil or other
liquid, or by water under pressure, as from a towns main or solely by compressed
air or other gases. The principle being the admission through a small aperture
under the piston in an inner chamber or cylinder of the air or liquid contained
under pressure in an outer chamber or jacket so that the piston is raised with any
degree of speed as the liquor is emptied from the cask, that may be found suitable
for raising the cask without muddling the contents.
In the accompanying drawing-Figure 1
A is the outer chamber containing air under pressure and water or oil.
B is the inner chamber or cylinder.
C is the small inlet for the admission of water or oil under piston.
D the frame fitted with friction bowls for the reception of the cask.
F back pressure valve, fitted with cap, for the admission of air under pressure-
into the chamber A.
G is the piston working in cylinder B.
The pressure in chamber A is so regulated that when a barrel of beer is placed
on it the weight of same forces the piston G to its lowest point, the liquid under
the piston being forced into the chamber A through the aperture C. As the beer
is drawn off and the barrel becomes lighter the pressure exerted in chamber A
forces the water through the aperture C and raises slowly and steadily the piston G
and consequently the barrel resting on same. It will be evident that no matter
how quickly the barrel is emptied the tilter can only rise at the speed regulated by
the size of the aperture C.
Figure 2. is another application of the same principle but with pressure obtained

page_text: from a water main H, which can be laid on to any number of tilters as shewn.
Each tilter is fitted with a separate valve I for the admission of the water under
the piston, the action being the same as previously described except that when the
piston in this case has been raised by the water under pressure from the main the
inlet valve H is closed and valve J is opened to let the water escape from under-
neath the piston and the tilter is then ready for the lifting of another barrel.
It must be understood that I do not confine myself to these precise details as the
carrying out of the principle can be greatly varied.
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 :-
1. The principle of tilting a barrel by the admission of air or liquid under
pressure to the underside of a piston through a small orifice in such a steady and
almost imperceptable manner that the contents of said barrel cannot be muddled
by the tilting process.
