PROVISIONAL SPECIFICATION.
A Vinegar Generator and Filter.
I. RUDOLPH, H. HERDER, Manufacturer, of Chicago, in the County of Cook, State
of Illinois, United States of America, do hereby declare the nature of this invention
to be as follows:-
My invention relates to a novel apparatus for manufacturing vinegar, and has for
its object the more speedy acetification of the mash employed, and at the same time,
the clarification and filtering of the product, and, with these objects in view, my
invention consists of the novel devices and combinations of devices hereinafter
described.
In the accompanying drawing, figure 1 represents a longitudinal vertical section,
figure 2 a sectional plan on line 2. 2 in figure 1, and figure 3 a vertical section on
line 3. 3. in figure 2, of the apparatus.
Corresponding letters of reference in the several figures of the drawing designate
like parts.
A denotes the cask, being barrel shaped and provided with diametrically opposite
trunnions a in its centre for supporting same in standard bearings B, to balance and
swing therein. This cask, near one end, is provided with three perforated
diaphragms C, D and E, the space between the diaphragms D and E being filled
with filtering material F, such as charcoal, gravel, and sand, and, at diametrically
opposite positions, the cask is tapped between the diaphragms C and D, and these
bung-holes are closed with stoppers G and G. The upper head of the cask is also
provided with a bung hole closed with a stopper H, and both heads of the cask are
tapped for connecting check valves I and I¹. Similar check valves J. J' and K, K¹,
having elbow nozzles are tapped into the sides of the cask close above and below the
line of the trunnions a, and all of these check valves, being provided with gravitating
valves, will close when turned to be below the line of the trunnions, and will auto-
matically open with swinging the cask for the check valves to occupy a position above
the line of the trunnions, all in a manner that whichever check valves I and J,
Jor and K, K', will be on the side and end of the cask that is turned to be up,
will allow a circulation of atmospheric air, while the check valves then below will be
hermetically closed by their own gravity.
Into the space between diaphragm, E, and the bottom of cask A, is tapped into the
side of the cask, a faucet L, and to the middle of the cask is attached a glass tube M
for indicating the quantity of the mash contained in the cask.
This cask, between diaphragm C and the upper head, is filled with wooden
shavings.
This cask, being filled with suitable fermented or distilled mash through bung-
holes H to a line slightly above the vertical centre of the cask, a certain amount of
the mash will adhere to the shavings and will rapidly acidify by being subjected to the
action of the current of atmospheric air admitted through check valves J and J
and I. After a short period, say four hours, the cask A is turned upside down,
whereby the check valves I. J. J will close, and the valves 1', K, K' will open, when
the current of air admitted through these valves will acidify-again.the mash adhering
to the shavings previously submerged in the mash. After the mash has been converted
into vinegar, in the manner above described, by repeated reversals of the position of
the receptacle, the receptacle is allowed to stand in the position in which it is shown
in figuré 1, and as the vinegar accumulates in the chamber below diaphragm E, it is
withdrawn through faucet L, all muggy matter being caught by the filtering material F
placed between diaphragms D and E.
;

page_text: From time to time the chamber between diaphragms C and D may be thoroughly
cleaned from all impurities collecting therein by removing stoppers G. G¹ and by
passing a current of water therethrough by inserting a hose into one bung-hole and
by allowing such water to escape through the opposite bung-hole, and also by
removing the faucet L and by inserting the hose in the tap hole thereof, and thus
forcing the water through the filtering material F in the direction opposite to that of
filtering the vinegar, which water then escapes through the bung-holes of stoppers G
and G¹.
It will be readily seen that a vinegar generator and filter thus constructed requires
the least manipulation, the several air ports being automatically opened and closed by
reversing the generating cask, and the filtering material being easily and readily
cleaned without taking the apparatus apart.

COMPLETE SPECIFICATION.
A Vinegar Generator and Filter.
I, RUDOLPH H. HERDER, Manufacturer, of Chicago, in the County of Cook, State
of Illinois, United States of America, 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 a novel apparatus for manufacturing vinegar, and has for
its object the more speedy acetification of the mash employed, and at the same time,
the clarification and filtering of the product, and with these objects in view, my
invention consists of the novel devices and combinations of devices hereinafter
described and specifically claimed.
Referring to the drawing accompanying my provisional specification, figure 1
represents a longitudinal vertical section, Figure 2, a sectional plan on line 2, 2, in
figure 1, and Figure 3, a vertical section on line 3, 3, in figure 2 of the apparatus.
Corresponding letters of reference in the several figures of the drawing designate
like parts.
A denotes the cask, being barrel shaped, and provided with diametrically opposite
trunnions, a, in its centre, for supporting same in standard bearings B, to balance
and swing therein. This cask, near one end, is provided with three perforated
diaphragms C, D and E, the space between the diaphragms D and E being filled with
filtering material F, such as charcoal, gravel, and sand, and at diametrically opposite
positions, the cask is tapped between the diaphragms C and D, and these bung-holes
are closed with stoppers G and G¹. The upper head of the cask is also provided with
a bung-hole closed with a stopper H, and both heads of the cask are tapped for
connecting check valves I and 1. Similar check valves J, J¹ and K, K¹ having
elbow nozzles, are tapped into the sides of the cask, close above and below the line of
the trunnions and all of these check valves-being provided with gravitating valves,
will close when turned to be below the line of the trunnions, and will automatically
open with swinging the cask for the check valves to occupy a position above the line
of the trunnions, all in a manner that whichever check valves I and J, J¹, or 1' and
K, K will be on the side and end of the cask that is turned to be up, will allow a
circulation of atmospheric air, while the check valves then below will be hermetically
closed by their own gravity.
Into the space between diaphragm E and the bottom of cask A, is tapped into the
side of the cask, a faucet L, and to the middle of the cask is attached a glass tube M
for indicating the quantity of the mash contained in the cask.
This cask, between diaphragm C and the upper head, is filled with wooden
shavings.

page_text: This cask being filled with suitable fermented or distilled mash through bung-
holes H to a line slightly above the vertical centre of the cask, a certain amount of
the mash will adhere to the shavings and will rapidly acidify by becoming subjected
to the action of the current of atmospheric air admitted through check valves J and J'
and I. After a short period, say four hours, the cask A is turned upside down,
whereby the check valves 1. J. J¹ will close, and the valves I', K, K' will open, when
the current of air admitted through these valves will acidify again the mash adhering
to the shavings previously submerged in the mash. After the mash has been
converted into vinegar in the manner above described by repeated reversals of the
position of the receptacle, the receptacle is allowed to stand in the position in which
it is shown in figure 1, and as the vinegar accumulates in the chamber below
diaphragm E, it is withdrawn through faucet L, all muggy matter being caught by
the filtering material F, placed between diaphragms D and E.
From time to time the chamber between diaphragms C and D, may be thoroughly
cleaned from all impurities collecting therein, by removing stoppers, G. G₁, and by
passing a current of water therethrough by inserting a hose into one bung-hole
and by allowing such water to escape through the opposite bung-hole, and also
by removing the faucet L and by inserting the hose in the tap hole thereof, and
thus forcing the water through the filtering material F in the direction opposite
to that of filtering the vinegar, which water then escapes through the bung-holes of
stoppers G and G¹.
It will be readily seen that a vinegar generator and filter thus constructed requires
the least manipulation, the several air ports being automatically opened and closed by
reversing the generating cask, and the filtering material being easily and readily
cleaned without taking the apparatus apart.
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. In a reversible vinegar generator, gravitating check valves for admitting
atmospheric air, substantially as set forth.
2. In a reversible vinegar generator, and in one end thereof, the three perforated
diaphragms C, D and E, with filtering material F packed between diaphragms D and E,
with bung holes leading from opposite sides into the chamber between diaphragms
and D, and with a faucet reaching into the chamber below diaphragın E, all substan-
tially as described and for the purpose specified.
