Improvements in Mustard Pots and the like.
1, HUGH DONALd Fitzpatrick, of 70 Wellington Street, Glasgow, Registered
Patent Agent, 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 new form of efflux-cock for mustard pots and
such like.
The improved cock closes automatically after being opened, and, as a result of its
peculiar construction, it cannot get out of order or fail to act.
On the annexed sheet of drawings,
Figs. 1 to 3 show the new efflux-cock, as applied to a hermetically closed, self-
acting mustard pot; Fig. 1 being a side elevation; Fig. 2 a vertical section, on
line
y-y, Fig. 3; and Fig. 3 a cross section on the line -a, Fig. 2.
Figs. 4 to 10 represent the efflux-cock to an enlarged scale; Fig. 4 being a side
view; Fig. 5 a longitudinal section, on the line Z, Z, Fig. 8; Fig. 6 a side view of
part of the cock; Fig. 7 a longitudinal section of Fig. 6; Fig. 8 a front view; and
Figs. 9 and 10, cross sections on the line Z, Z, Fig. 5.
Referring to the drawings:-
The mustard pot A in the example shown (Figs. 1, 2 and 3) is of cylindrical
shape. It is tightly covered by a lid B. The mustard is put into this pot and
covered by a piston C, which latter may, with advantage, be covered with a fabric,
saturated with vinegar. The fabric ensures that the piston will work tightly in
the pot. The lid B may be secured tightly in place by being made to work in a
bayonet joint, or it may be screwed on. Inserted between the piston C and lid B,
is a spiral spring D. This spring is compressed, when the lid is secured in place,
and, as a consequence, it re-acts on the piston C and forces it downwards, thereby
maintaining sufficient pressure on the mustard, in the pot, as io force it out, at a
convenient velocity, immediately the efflux-cock is opened.
The outlet socket or discharge orifice E is arranged as low down as possible in
the mustard pot. Over the socket E is fitted a tube or casing F, which has fitted
on it, at the outside, a spring, and it has also an opening a, or slit, on its underside.
The front of the tube is completely open, as shown at Fig. 5, so that a second
smaller concentric tube G may be inserted in it (see Figs. 2, 3 and 5). The tube G
is closed on its outer end, as shown. Pinned to the front end of the small tube G,
is a small hand-lever g' (see Figs. 4 and 8). The lever is fulcrumed on the pin and
has, on its shorter arm, a small catch g, which catches the end of the spring f
The spring is so made, as to normally press downwards, so that the lever usually
occupies the position, shown in full lines at Fig. 8. The lower side of the internal
tube G, has an opening (Figs. 3, 6, 7, 9 and 10), cut out of it. This opening
corresponds to and is of the same size as the slit or opening a in the tube F. The
outer end of the tube F is cut away segmentally at i and (Figs. 4 and 8) so as
to allow sufficient movement to the lever. The internal tube G, at its outer end,
is not flush with the tube F, but is countersunk, as shown at Figs. 4 and 5. The
parts j, and j', at the front of the tube F, which are not cut away, serve as stops to
limit the movement of the lever g'. As the outer end of the spring is bent down
over the catch g of the lever g, as shown at Fig. 8, the internal tube G can be
turned, within the tube F, without pulling it outwards.
When the efflux-cock is closed, the openings a, b, do not coincide with one
another (see Fig. 9) and the lever ' is in the normal position, shown at Fig. 8.

page_text: The line 2-2, Fig. 9, indicates the position of the lever g', when the tube G is
in the closed position. By pressing down the lever y' to the position indicated
in dotted lines at Fig. 8, and the line 23-23, Fig. 10, the tube G is turned
round until the openings a, b correspond, as shown at Fig. 10, and the mustard
or other fluid in the pot is then forced out by the pressure of the piston C.
When the lever g' is pressed down to open the cock, the spring is bent up, so
that, immediately the pressure is taken off the lever, it is forced back, by the action
of the spring on the catch 7, to its normal position. The tube G is turned back
again and the cock is, thus, automatically closed.
The internal tube G being hollow and filled with fluid,-which escapes only
through the openings a, b, there is no danger of clogging or choking, when the
cock is closed, as the fluid is simply cut off by the turning action of the tube G
inside the tube F.
When it is desired to clean the improved cock, the spring catch f, g, is disengaged,
and the tube G can then be drawn out. When this is done, the tubes F and G
can be thoroughly cleaned.
The improved cock can be used, on account of its adaptability, for easy cleaning,
for any pulpy or viscous fluids.
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 :-
:―
An efflux-cock for pots or vessels, for mustard or other viscous fluids, consisting
of a tube For its equivalent, which is fixed to the vessel or pot, and has an
opening (a) in its under side; a second concentric tube G, having an opening (6)
in it, and which works inside said tube F; and a lever (g), provided with a
catch () or equivalent, fitted on the tube G, said lever being, normally, retained
in the closed position, by a spring; the cock being opened, against the pressure of
the spring, by pressing down the lever (g), until the openings (a), (b), in the
tubes F, G, come in line with one another, substantially as hereinbefore described,
with reference to the drawings annexed.
Dated this 7th day of March 1892.
