COMPLETE SPECIFICATION.
Apparatus for Automatically Drawing off Viscous Substances.
1, LEBERECHT HELNRICH AUGUST WILHELM SACK, Manufacturer, of Berlin, in the
Kingdom of Prussia and German Empire, 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 apparatus for automatically drawing off thick liquid or
viscous substances and has for its object to effect by automatic means the withdrawal
from the vessels containing them, of viscous articles of commerce such as syrups honey,
mustard, thick oil colours lubricating substances and the like this apparatus likewise
preventing the residuum left in the said vessel from being covered with dust or a crust
during the further preservation of the said substances.
The accompanying drawings illustrate at Figures 1 to 4 several forms of the said
apparatus while Figures 5 and 6 are details of the same. The apparatus shewn
in Figure 1 consists essentially of a vessel or receptacle A, and of a spiral spring B.
The vessel A, which is carried upon the feet a, receives gradually the liquid for sale C,
which is fed through the upper opening b, and drawn off by means of a cock D, fixed
to the lower part of the said receptacle. The cock D, is connected to the vessel by
means of a tube f, the outer end of the opening of which leads to the small lateral
channel g, of the plug g, when the latter is dispressed i.e. when liquids are to be drawn
off from the vessel A, (Figures 5 and 6). To close the cock, the plug need only be
raised and brought in the position shown in Figures 1 and 3, in which it is held by an
inner spiral spring i (Figure 5) or by a flat spring h, the forked end of which surrounds
the plug and prevents the latter from turning (Figure 6). The upper end of the
spiral spring B, is fixed to a lid covering the opening b, of the vessel A, while its
lower end is connected to a plate c', and is surrounded by a telescopic tube d. Over
the lid c, is arranged the bell cover e, which closes the vessel at its upper edge, being
fixed thereto by a screw thread e', or by any other equivalent means such as a bayonet
joint, hinges on a lock. The last named devices are not shown on the drawings as
they are well known, and in general use amongst mechanicians. It is obvious that
the plate c', need not be firmly connected with the spiral spring B.
When the above described apparatus is required for use the vessel A, is first filled
with the viscous substance C, as high up as the line a, a, the spring B, is then inserted
between the cover e, and the plate c', and in close proximity to the telescopic tube d,
so as to bear upon the substance C, after which the vessel is closed by the bell or

part of the substance in the vessel A, lias to be drawn off the plug g, is merely pressed
downwardly to bring its channel g', in communication with the opening in the tube f,
of the vessel. Owing to the expansion of the spiral spring B, the substance C, is
pressed through the tube f, and the plug g, until the latter reaches its lowermost
position Figures 5 and 6. As soon therefore as a sufficient quantity of substance has
been withdrawn from the vessel A, the plug g, will have to be brought back to its
uppermost position Figures 1 and 3. The plate c', connected with the spiral spring B,
preserves the remainder of the substance left in the vessel A, from direct contact with
the atmospheric air and likewise in common with the lid c and the bell e, prevents
dust from entering the vessel and contaminating the substance. According to this
arrangement no crust can be formed upon the said substance C.
the
The apparatus shown in Figure 2 is arranged in a similar manner, with this
difference that the tube k, terminating with a cock D, passes through the bell e,
cover c, the spiral spring B, and the plate o¹, and leads nearly to the bottom of the
vessel filled with the substance C. In this arrangement no telescopic tube d, enclosing
a spiral spring B, is provided as in Figure 1. Such an apparatus filled with mustard

page_text: will be found advantageous for household use. For this purpose the same is provided
with projections 1, by means of which it can be placed upon one of the rings of a
castor, furnished likewise with oil and vinegar bottles, but not shown on the drawings.
When mustard is required, a spoon is held under the cock D, and the plug g, is pressed
downwards and subsequently raised as soon as a sufficient quantity has been with-
drawn. The spring B, operates in the same manner as the spring of Figure 1, by
forcing the substance through the pipe k, and the cock D. In the automatic drawing
off apparatus shown in Figure 3 a tube furnised with a cock D, is used and consists of
several sections or pipes arranged telescopically and firmly connected with the plate c¹,
bearing upon the substance C. In this arrangement. the substance is constantly being
drawn off at the top, while in the arrangement shown in Figure 2, it is on the contrary
always withdrawn at the bottom.
Figure 4 shows an apparatus provided at its lower part with a sole or pedestal a',
and designed for household use the sole a', and the vessel A', being formed in one
piece and made of porcelain or glass.
The plug is preferably cut obliquely at the bottom in order to prevent a large drop
from remaining suspended thereto; a drip tray may however be provided and placed
below the plug.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed i declare that what I
claim is :-
1. An automatic drawing off apparatus characterized by the arrangement of a plate
bearing upon the substance or viscous liquid placed in a vessel or receptacle and
operating under the action of a spiral spring, in which the opening of a cock connected
with the inside of the said vessel causes the substance to be discharged so long as such
cock remains open substantially as described.
2. In automatic drawing off apparatus the combination of a spiral spring with a
telescopic pipe substantially as described.
3. In automatic drawing off apparatus the combination of a spiral spring with a
pipe furnished with a cock and leading to the bottom of the receptacle substantially as
described.
4. The automatic drawing off apparatus arranged constructed and operating sub-
stantially as above described and shown in the accompanying drawing.
