Improved Means and Apparatus connected with and for the Marking

We, GEORGE DUNCAN MACDOUGALD, of Edenbank, Wormit, County of
Fife, N.B. Analytical Chemist, and THE LONDON AND DUNDEE SYNDICATE LD..
of St. Swithin's Lane, London, Merchants, 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 improved means and apparatus connected with and for
the marking of soap tablets, cakes, or bars with iudelible colour.
For the purpose of this invention and as represented in the annexed drawings,
Figure 1 being a sectional elevation of a complete apparatus with the hermetically

page_text: Bealed lid in a closed position; Figure 2 an end elevation with the lid open,
Figure 3 an elevation of one of the trays or frames into which soap tablets
preferably on their longer ends are inserted, we prepare a strong tank A with
hermetically closing lid B and charge it with skeleton trays or cages C containing
tablets, cakes, or bars of soap C' which have been previously pierced by needles
to the desired depth on one, or on both, or more faces, the tank so charged is then
exhausted of air by the pipe D to form a vacuum, and the suction cock E closed.
Colour liquid from the reservoir F by the pipe G is admitted or is forced into the
tank until the soap is practically covered, the holes in the soap becoming fully
charged thereby. The vacuum is now destroyed by the release and opening of
the lid B for the liquor to flow back into the colour reservoir F (or it may be
allowed to run to waste by the pipe H). The tap G₁ is now closed and the waste
tap H opened, a powerful spray of water being then injected to wash the
superfluous or surface colour from the soap, which after the necessary draining
bas taken place the trays or cages can be removed and the soap exposed for
drying.
We prefer to provide the top edge of the tank A with a rubber fillet J and
hinge the lid, as shown at Figure 2, and to ensure a close fit of the lid when closed
we fit toggle screws K, K, to side lugs and after passing said screws into slots of
the lid, secure the same down by loop nuts L, L.
The soap frames or cages C are in skeleton forin and have a yoke M, as at
Figure 3, for convenience of lifting them into and out of the tank A.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what.we
claim is :-
The apparatus shown on the annexed drawings, or any modification thereof, and
within which frames containing tablet and like soaps previously needle holed can
be inserted and hermetically enclosed and the means herein before described for
causing the holes to become charged with a colour liquor as and for the purposes
explained and by the means set forth.
