page_text: LETTERS PATENT to John Koch and Jean Mathieu Charvet, both of No. 37,
Warner Street, Clerkenwell, in the County of Middlesex, for the Invention
of "AN IMPROVED CONSTRUCTION OF VESSEL OR RECEPTACLE FOR HOLDING,
PRESERVING, AND DELIVERING MUSTARD OR OTHER CONDIMENT FOR TABLE
Tian"
Sealed the 2nd April 1880, and dated the 7th October 1879.
PROVISIONAL SPECIFICATION left by the said John Koch and Jean Mathieu
Charvet at the Office of the Commissioners of Patents on the 7th October
1879.
JOHN KOCH and JEAN MATHIEU CHARVET, both of No. 37, Warner Street,
Clerkenwell, in the County of Middlesex. "AN IMPROVED CONSTRUCTION OF
VESSEL OR RECEPTACLE FOR HOLDING, PRESERVING, AND DELIVERING MUSTARD
OR OTHER CONDIMENT FOR TABLE USE."
Our Invention relates particularly to an improvement upon the ordinary mustard
pot, which if made in the ordinary way of glass becomes unsightly directly any of
its contents has been removed; and of whatever material the mustard pot has
hitherto been made air has not been excluded from the made mustard, which
therefore rapidly spoils and is wasted.
We propose to apply the principle of a cylinder and piston to the construction
of a mustard pot or other vessel for holding, preserving, and delivering condiments
at table.
We make a cylindrical pot, box, or vessel, of metal, glass, porcelain, or any
suitable material, with a lid or cover, which may be screwed or otherwise closely
fitted thereon. This lid or cover will have a hole in the centre for the passage of
a piston rod, at the bottom of which, within the pot or vessel, will be a plate of
any desired thickness, and of a diameter which will cause it by its leather or other
packing to be always in close contact with the sides of the pot or vessel, the other
end of the piston-rod being provided with a button or knob. At any convenient
part of the pot or vessel we form or fit a spout, the mouth of which we may close
by any suitable device.
The action will be as follows:-The mixed mustard being introduced into the
pot or vessel the piston will be placed there upon, and the cover or lid screwed or
otherwise fastened on. When a person desires to place the mustard upon his
plate he simply presses with his finger upon the top of the piston rod, the piston
lowers, pressing upon the mustard, and a quantity, regulated by the degree of
pressure, issues by the spout on to the plate; directly the finger is removed from
the piston rod the delivery ceases.
We need scarcely observe that we may make our improved mustard pots or table
vessels of any shape and size, and of any material which we may find suitable.

on the 5th April 1880.
JOHN KOCH and JEAN MATHIEU CHARVET, both of No. 37, Warner Street,
Clerkenwell, in the County of Middlesex. "AN IMPROVED CONSTRUCTION OF
VESSEL OR RECEPTACLE FOR HOLDING, PRESERVING, AND DELIVERING MUSTARD
OR OTHER CONDIMENT FOR TABLE USE."
Our Invention relates particularly to an improvement upon the ordinary mustard-
pot, which, if made in the ordinary way of glass, becomes unsightly directly any
of the contents has been removed, and of whatever material the mustard-pot has
been hitherto been made air has not been excluded from the made mustard, which
therefore rapidly spoils and is wasted.
We propose to apply the 'principle of a cylinder and piston to the construction of
a mustard-pot or other vessel for holding, preserving, and delivering condiments at
table.
On the accompanying Sheet of Drawing forming part of this Specification,―
Figure 1 represents an elevation of a mustard pot embodying our Invention.
Figure 2 being a sectional elevation, and
Figure 3, a top plan view of same.
It is composed of a cylindrical pot, box, or vessel A, which may be made of metal,
glass, porcelain, or any suitable material, with a lid, cap, or cover B, which may be
screwed or otherwise closely fitted thereon; this lid or cover has a hole in the
centre for the passage of a piston rod D, at the bottom of which, within the pot or
vessel, is a plate or piston C (Fig. 2) of any desired thickness, and made air tight
with the cylinder by means of the leather packing c, as shown, in any suitable
manner.
At any convenient part of the vessel we form or fit a spout (E), the mouth of
which we may, if desired, close or cover by any suitable device.
The action is as follows:-The mixed mustard or other condiment being intro-
duced into the pot or vessel at F the piston is placed thereupon, and the cover or
lid screwed or otherwise fastened on. When a person desires to place some mustard
upon his plate he simply presses with his finger upon the knob at the top of the
piston rod D, thereby lowering the plate or piston C, which presses upon the
inustard (F), and a quantity, regulated by the degree of pressure, issues by the
spout E on to his plate. Directly the finger is removed from the piston rod the
delivery ceases.
We need scarcely observe that we may make our improved mustard pots or
table vessels of any shape and size, and of any material which we may find
suitable.
Having now described and ascertained the nature of our said Invention, and
in what manner the same is or may be performed,
We claim as secured to us by the hereinbefore in part recited Letters Patent,-
The use of a mustard-pot or other vessel or receptacle for holding, preserving,
and delivering condiments for table use, constructed and arranged to operate as
herein before described and shown on the accompanying Sheet of Drawing.
In witness whereof, I, the said John Koch, have hereunto set my hand and
seal, this Fifth day of April, in the year of our Lord One thousand eight
hundred and eighty.
