An Improved Mustard Pot.
We HENRY BARTZ of 12c Rosinenstrasse Charlottenburg Technical Engineer
and JAMES ROSENGARTEN of Passage Hotel, Berlin, Captain, both in the Empire
of Germany do hereby declare the nature of this invention and in what manner
is to be performed to be particularly described and ascertained in and by
the following statement :-
the
same
Mustard pots or receivers in which mustard is kept prepared for table use have
disadvantages in use, amongst which is the unsightly appearance produced by the
drying up of the mustard and the entrance of dust and the like, more especially
noticeable in public restaurants and similar places. Where also the mustard is
removed by means of a spoon a considerable quantity remains in the spoon and in
the holder and becomes dry or otherwise useless thus leading to considerable
waste.
To avoid these disadvantages mustard pots have been made upon the principle
long ago applied to vessels containing thick oil colours by which as much mustard
as is needed may be pressed out of a narrow opening by the use of a piston with
suitable means such as a piston rod, lever gear or toothed devices for pressing the
piston onto the mustard in such vessel and thus expelling a desired quantity from
the orifice. Such parts however come in contact with the mustard and present
disadvantages which are obviated by the present invention in which the mustard is
expelled by air pressure produced by devices which do not come into contact with
the mustard.
The improved mustard pot is shown in the annexed drawing in section.
On a suitable base A rests loosely the pot B which may either end direct below
in an outflow opening or may have as shown an interior removable vessel C ending
with said opening D below and open above. This vessel can be filled with prepared
mustard up to its upper rim and over the mustard may be placed a disk M of
parchment paper or the like having a small hole in the centre. The lid is then
screwed on the lower part B. This lid E contains the cylindrical or other bellows F
of which the two end plates a and b are preferably made of vulcanite while the
bellows portion is made of soft vulcanized rubber. The lower plate a is held
between the inner rim or flange of the lid E and the rim of vessel B and in the
middle is a hole d. The plate b has also an air hole closed from within by valve d¹.
The stem H ending above in knob G is secured to plate and passes through a hole
in the lid E, in which also are passage ways for entrance of air into the lid when
the bellows are compressed.
On lifting the vessel from its base A and applying pressure to the knob G the
air pressure from the bellows, evenly distributed over the surface of the mustard by
the disk M, causes the latter to issue from the orifice D. On relieving the knob G
from pressure the elasticity of the bellows is sufficient to raise the latter and the
bellows refill from the orifice at d', but not sufficiently quickly to prevent production
of a slight inward pressure at the orifice D which has the effect of slightly with-
drawing the mustard and leaving the orifice D always clean. The orifice D may
dip into a small cup L inserted in the base A and intended to be filled with vinegar
to prevent drying of the mustard in and about the orifice D. The bellows F could
be replaced by an elastic ball or vessel provided with the necessary openings.

page_text: Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed we declare that what
we claim is;-
1. A mustard pot or receiver consisting of a vessel having an orifice D with a
cover E containing a compressible hollow bellows or equivalent compressible boly
adapted on compression to produce an air pressure on the prepared mustard in the
vessel for the purpose described.
2. The construction of mustard pot as described herein with reference to the
drawing hereto annexed.
