page_text: I, FRIEDRICH FOERSTER, of Karlsruhe, in the Grand Duchy of Baden, Germany,
Engineer, (Kreuz Strasse, 17,) do hereby declare the nature of this invention to
be as follows:-
This invention relates to a mechanical contrivance for mustard-pots.by means
whereof it is made possible to take out mustard in what quantity may be desired
without removal of a cover or admission of the exterior air.
The subject of my invention is a mustard-pot the interior of which from the
upper to the under portion is at first funnel-shaped, then cylindrical for a short
stretch, then funnel-shaped again to a small bottom or floor. It is.movably closed
and held tight above. The bottom has a perforation and the mustard can be
served through such outlet or can be held in place by the turning of an internal
contrivance furnished with a spindle by means of a circular handle or wheel-
grip which projects from the cover.
In the accompanying drawing, where like letters denote like parts, Figure 1
gives a vertical section of the contrivance representing my invention.
Figure 2a sectional view taken on the line A-B of Figure 1.
The body of mustard-holder (A), which may advantageously be constructed
of porcelain or glass, is as above described internally, and as constructed of a
cylindrical form in outward appearance as shown in Figures 1 and 2. It is
closed by a cover (B) screwed on by means of a thread. Above the centre-
piece (B1) of this cover is a handle or wheel-grip (C) which is joined to an interior
spindle (D). The spindle (D) set in the cover (B) and hanging down to the out-
let (A 1) of the mustard-holder (A) is united with a worn or transport-screw (E),
somewhat resembling a corkscrew in form, which is fixed spirally round its lower
portion. This screw (E) is arranged to work with the revolution of the spindle
in the under cylindrical space (A2) of the holder (A). During rotation in the
appropriate direction of the worm, it forces the mustard out at the outlet (A1)
but while not being rotated retains the mustard in the holder.
To ensure that during the screwing out of the mustard the spindle (D) shall
not give backwards, a plate (D 1) is fixed on the same within the holder lying
lightly against the cover (B).
(F) is a packing of rubber or other suitable material placed in the hollow
part of the centre-piece (B1) of the cover (G) is a packing ring of rubber or the
like for the outer rim of the holder.
To use this mechanical mustard-pot, it is held in one hand over the plate.
Then, with the other hand, a short turn of the handle or wheel-grip is given in
the direction of the arrow marked on the cover. To fill afresh with mustard,
the top (B) is unscrewed from the body, the spindle and transport-screw or worm

page_text: remaining with the former. During use of the mustard-pot equalisation of the
air-pressure above the holder follows because the upper fitting of the spindle is
not hermetically closed.

I, FRIEDRICH FOERSTER, Kreuzstrasse, 17, Karlsruhe, Grand Duchy of Baden,
Germany, 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 relates to a mechanical contrivance for mustard-pots by means
whereof it is made possible to take out mustard in what quantity may be desired
without removal of a cover or admission of the exterior air.
The subject of my invention is a mustard-pot the interior of which from the
upper to the under portion is at first funnel-shaped, then cylindrical for a short
stretch, then funnel-shaped again to a small bottom or floor. It is movably closed
and held tight above. The bottom has a perforation and the mustard can be
served through such outlet or can be held in place by the turning of an internal
contrivance furnished with a spindle by means of a circular handle or wheel-
grip which projects from the cover.
In the accompanying drawings which are those filed with the Provisional
Specification and where like letters denote like parts, Fig. 1 gives a vertical section
of the contrivance representing my invention.

Figure 2 a sectional view taken on the line AB of Fig. 1.
The body or mustard-holder (A), which may advantageously be constructed
of a cylindrical form in outward appearance as shown in Figures 1 and 2. It
is closed by a cover (B) screwed on by means of a thread. Above the centre-
piece (11) of this cover is a handle or wheel-grip (C) which is joined to an
interior spindle (D). The spindle (D) set in the cover (B) and hanging down to
the outlet (A 1) of the mustard-holder (A) is united with a worm or transport-
screw (E), somewhat resembling a corkscrew in form, which is fixed spirally
round its lower portion. This screw (E) is arranged to work with the revolution
of the spindle in the under cylindrical space (A2) of the holder (A). During
rotation in the appropriate direction of the worm it forces the mustard out at
the outlet (A1), but while not being rotated retains the mustard in the holder.
To ensure that during the screwing out of the mustard the spindle (D) shall
not give backwards, a plate (D1) is fixed on the same within the holder lying
lightly against the cover (B).
(F) is a packing of rubber or other suitable material placed in the hollow
part of the centrepiece (B 1) of the cover. (G) is a packing ring of rubber or the
like for the outer rim of the holder.
To use this mechanical mustard-pot, it is held in one hand over the plate.
Then, with the other hand, a short turn of the handle or wheel-grip is given in
the direction of the arrow marked on the cover. To fill afresh with mustard,
the top (B) is unscrewed from the body, the spindle and transport-screw or worm
remaining with the former. During use of the mustard-pot equalization of the
air-pressure above the holder follows because the upper fitting of the spindle is
not hermetically closed.

page_text: Having now given a clear and exact description thereof I declare that what I
claim as my invention is:-
A mechanical mustard-pot, the interior of which from the upper end to the
under portion is at first funnel-shaped, then cylindrical for a short stretch, then
funnel-shaped again to a small bottom with a perforation, and specially dis-
tinguished herein, that a transport-worm (E) is in the holder (A), which worm
is fixed round the lower portion of a spindle, set in the cover (B), projecting from
the latter and furnished with a handle or wheel-grip (C), by which a rotation
of the spindle may be effected, which forces mechanically the mustard out of the
holder (A) at the outlet (A 1).
