PROVISIONAL SPECIFICATION.
Improvements in Pots for Mustard and the like.
I, MALCOLM CAMPBELL MACLEOD, of 36 Harrington Gardens, South Kensington,
in the County of Middlesex, Gentleman, do hereby declare the nature of my inven-
tion for "IMPROVEMENTS IN POTS FOR MUSTARD AND THE LIKE to be as
follows:-
"
According to my invention I construct the receptacle for the mustard of cylindrical
form with a conical or tapered end, through the extremity of which is an orifice for
the escape of the mustard, and which orifica is fitted with a nozzle of flexible
material, say india-rubber, or gutta-percha, which closes the orifice when it is not
subject to pressure from within.
The internal surface of the cylindrical vessel, or an inwardly projecting annular
band or rim thereof, is made with a screw thread into which works a screw cut on
the exterior surface of a plunger, which plunger may thus be screwed into or
withdrawn from the cylindrical container at pleasure.
The manner in which the apparatus is intended to be used is as follows: some
mustard or other like semi-fluid or viscous matter having been placed in the said
vessel the plunger is screwed in until it comes in contact with the mustard or other
matter, if then, when some of the contents is required for use, the screw plunger is
turned so as to screw it further in, some of the contents of the cylinder will be
expelled at the other end, the flexible covering of the orifice being pushed open by
the pressure of the contents.
I provide a tripod or any other suitable or ornamental stand to support the
apparatus with, preferably, a little dish fixed beneath the orifice of the cylinder.

"
I, MALCOLM CAMPBELL MACLEOD, of 36 Harrington Gardens, South Kensington,
in the County of Middlesex, Gentleman, do hereby declare the nature of my inven-
tion for "IMPROVEMENTS IN POTS FOR MUSTARD AND THE LIKE and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:—
According to my invention construct the receptacle for the mustard of cylindrical
form with a conical or tapered end through the extremity of which is an orifice for
the escape of the mustard, and which orifice is fitted with a nozzle of flexible material,
say india-rubber, or gutta percha, or preferably a flexible metallic nozzle which
closes the orifice when it is not subject to pressure from within.
The internal surface of the cylindrical vessel, or an inwardly projecting annular
band or rim thereof, is made with a screw-thread into which works a screw cut on
the exterior surface of a plunger, which plunger may thus be screwed into or with-
drawn from the cylindrical container at pleasure.
The manner in which the apparatus is intended to be used is as follows: Some
mustard or other like semi-fluid or viscous matter having been placed in the said
vessel the plunger is screwed in until it comes in contact with the inustard or other
matter, if then, when some of the contents is required for use, the screw plunger is
turned so as to screw it further in, some of the contents of the cylinder will be
expelled at the other end, the flexible covering of the orifice being pushed open by
the pressure of the contents.

page_text: I provide a tripod or any other suitable or ornamental stand to support the
apparatus, with preferably a little dish fixed beneath the orifice of the cylinder.
In order that iny invention may be fully understood I shall now proceed to describe
the same in detail reference being had to the accompanying sheet of drawings
forming part of this my Specification and to the figures and letters of reference
marked thereon.
Fig. 1 is an elevation of my said invention with parts of the various pieces
removed to show the internal arrangement.
Fig. 2, is a section of the same.
Fig. 3, is a plan taken on the line c. y. Fig. 4 represents the apparatus.removed
from its stand, and Fig. 5 represents the stand by itself.
or cover.
The mustard holder is composed of two concentric cylinders, the inner one A
having a screw-thread a on it's inner surface, and the outer one A¹ serving as a case
B is a plunger either solid, or closed at its lower extremity, and having a
screw thread on it's outer surface corresponding with and working into the
thread a.
B¹, is a cylindrical casing or cover concentric with and covering the
plunger B, and working into the space between the cylinders A and A. C is a
milled, or ornamental, or other head, by which the plunger B and cylinder B¹ may be
rotated and screwed into or from the cylinders A and A'. The cylinders A and A',
are united at their lower extremities and terminate in a conical or other nozzle, the
point or apex of which is divided or pierced by a number of slits, so that the end
thereof is formed by the meeting of a number of flexible points or fingers, which
yield and bend outwards when the contents are pressed downwards, and allow the
mustard to pass out, closing again as soon as the pressure is relieved.
D, is a ring fixed on the cylinder A', and serves to support the apparatus on it's
stand. D', is a corresponding ring fixed to the legs E on which the ring D rests
when the apparatus is on it's stand, and from which position the apparatus may be
lifted in order that the user may squeeze out some of it's contents into his plate, and
F is a dish or pan which receives any waste mustard. It will be obvious that the
screw-threads may be dispensed with and the parts made to slide upon each other on
pressure being applied to the head, or the screws may be cut on the outer surface of
the cylinder A and the inner surface of the cylinder B so as to leave a smooth
surface exposed to the mustard and the stand may have more than three legs or be
otherwise varied in shape without departing from my invention, but I prefer to
construct it as described.
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) A cylindrical mustard pot from which the contents are expelled by a screw
plunger substantially as described and shown in the drawings.
(2) A container for mustard or other like articles consisting of a cylindrical
receptacle, a plunger working therein by which the contents may be expelled as
required for use substantially in the manner and for the purpose set forth and shown
in the Drawings.
