Improvements in or pertaining to Drums or Vessels with Covers for
Containing Substances, such as Anti-fouling Compositions and
Paints, having Constituents Liable to Settle."
I, VIVIAN BYAM LEWES, of 19 Park Row, Greenwich, in the County of Kent,
Professor of Chemistry, do hereby declare the nature of this invention to be as
follows:--
Antifouling compositions and paints contain heavy mineral constituents which when
the composition or paint is sent out in a drum or vessel are liable to settle to the
bottom so that when the drum or vessel is opened the composition or paint is not of a
uniform nature or consistency, and no reliable means have heretofore, so far as I am
aware, been provided to ensure an efficient stirring and remixing of the compound
preparatory to its use.
Now my invention has reference to the combination with the drum or vessel or with
a part of the drum or vessel in which any compound such as above referred to is to be
stored of means whereby the contents of the drum or vessel will be stirred or agitated
in the act of opening the drum or vessel to remove its contents for use.
An arrangement for this purpose is as follows:-
The drum is made with a fixed rod on the under side of the cover; this rod reaches
to the bottom of the drum. At the end of the rod iron blades are fixed into a cap and
at right angles to the rod and to each other, the blades being slightly sloped. There
may be four blades. The cover is fitted to the drum with a coarse screw having any
suitable number of turns-say six-in such a manner that in order to open the drum
the arms will be caused to revolve a corresponding number of times within the
drum; thus they will stir up any deposit and on the lid being pulled off the arms
rising through the liquid contents of the drum will further tend to remix the
ingredients.

COMPLETE SPECIFICATION.
Improvements in or pertaining to Drums or Vessels with Covers for
Containing Substances, such as Anti-fouling Compositions and
Paints, having Constituents Liable to Settle.
I, VIVIAN BYAM LEWES, of 19 Park Row, Greenwich, in the County of Kent,
Professor of Chemistry, de 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 :-
Antifouling compositions paints and certain liquids contain heavy mineral con-
stituents which when the composition or paint is sent out in a drum or vessel, ure
liable to settle to the bottom so that when the drum or vessel is opened the composition
or paint is not of a uniform nature or consistency, and no reliable means have hereto-
fore, so far as I am aware, been provided to ensure an efficient stirring and remixing
of the compound preparatory to its use.
Now my invention has reference to the combination with the drum or vessel or
with a part of a drum or vessel in which any compound such as above referred to is to
be stored of means whereby the contents of the drum or vessel will be stirred or
agitated in the act of opening the drum or vessel to remove its contents for use.

page_text: An arrangement for this purpose is shewn in elevation in Fig. 1 applied to a drumm
or vessel which is shewn in vertical section. ] is the drum or vessel provided with a
removable cover 2 to the under-side of which is fixed a rod 3 that reaches to the
bottom or nearly so of the drum. At the lower end of this rod is a boss 4 to which
iron arms or blades 5 are fixed so as to be at right angles to the rod, and it may be to
each other, the blades being slightly sloped. There may be four blades as in the
example shewn, but there may be more or less according to requirement. The cover 2
is fitted to the drum with a coarse screw at 2* having any suitable number of turns-
say six-in such a manner that in order to open the drum the arms or blades will be
caused to revolve a corresponding number of times within the drum; thus they will
stir up any deposit, and on the cover being pulled off, the arms or blades rising through
the liquid contents of the drum will further tend to remix the ingredients.
Fig. 2 illustrates a modification in which, in lieu of a number of projecting arms or
blades as in Fig. 1, the rod carries a screw blade 5° that makes from two to three
turns around the rod 4. In other respects the arrangement is similar to that shewn in
Fig. 1.
With this arrangement as the cover 2 is unserewed, the screw blades 5* will
cut up the sediment at the bottom of the drum and lift it so as to mix it with the
composition or paint in the upper portion of the drum.
Fig. 3 shews another construction somewhat similar to that illustrated in Fig. 2,
which may be used when a greater number of turns are required. In this arrange-
ment there projects upwardly from the bottom of the drum, an externally screw
threaded pin 6 with a large number of turns on to which screws the lower part of the
rod 4 which is formed with a corresponding internally screwed part 7 for the
purpose.
As will be evident the forms of the agitating arms or blades, or complete screw
blades as the case may be, can be modified; for instance the screw blades instead of
being of decreasing diameter as they proceed upwards as in Figs. 2 and 3 may be of
the same diameter throughout.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. For containing substances such as anti-fouling compositions and paints having
constituents liable to settle, a drum or vessel having a cover provided with means
substantially as described, whereby the contents of the drum or vessel will be stirred
or agitated in the act of opening the drum or vessel preparatory to removing its
contents.
2. The several constructions of drums or vessels with covers and stirrers or agitators
for containing substances such as anti-fouling compositions and paints having con-
stituents liable to settle substantially as hereinbefore described with reference
respectively to and shewn in Fig. 1; in Fig. 2; and in Fig. 3 of the drawings
annexed.
