Improvements in Boxes for Blacking and other Substances which
are required to be Kept in a Moist Condition.
I, JOHN STEVENSON, of No. 114 Moss Street, Blackburn, in the County of
Lancaster, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the manufacture and construction of
boxes or pots for blacking, and other substances which are required to be kept in
a moist condition, the object being to construct a box or pot in which a supply of
blacking can be kept in a moist state for a long period without renewing the supply
of water or other damping medium, there being a reservoir for a supply of liquid,
which maintains the contents of the box in a moist condition.
According to this invention, I employ a box, preferably of tin, around the
inner edge of which is a flange or rim, either formed by spinning over the edge of
the box, or of putty or cement. Inside the flanged portion, which is slightly
concave, I force a saucer of porous wood, unglazed earthenware, or other porous
material. Beneath the porous saucer, the box forms a reservoir for the damping
liquid, which is inserted into same through a tube or pipe closed by a cork or
screw cap.
The blacking or other substance is placed in the
liquid is by capilliary attraction drawn through or

Improvements in Boxes for Blacking and other Substances which
are required to be Kept in a Moist Condition.
1 JOHN STEVENSON of 114 Moss Street, Blackburn in the County of Lancaster,
Mechanic, 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 improvements in the manufacture and construction of
boxes or pots for blacking, and other substances which are required to be kept in
a moist condition, the cbject being to construct a box or pot in which a supply of
blacking can be kept in a moist state for a long period without renewing the supply
of water or other damping medium, there being a reservoir for a supply of liquid,
which automatically maintains the contents of the box in a moist condition.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings
in which :-
Fig. 1. is a plan view of the improved box, the lid or cover being removed.

page_text: Fig. 2. is a sectional elevation of the improved box and lid or cover, the latter
being removed from the box.
Fig. 3. is a detail.
Fig. 4. is a sectional elevation of a modification of the box.
According to this invention I employ a box 1 preferably of tin, and inside this
box 1 is placed a dish or saucer 2 of open grained wood, unglazed earthenware, or
other porous material, such dish or saucer 2 being bevelled, or recessed on its
underside so as to leave a waterspace 3 between the saucer or dish 2 and the box 1.
The box has a tube or pipe 4 fixed in it so that a supply of water or other
damping liquid can be poured into the waterspace 3, after which the tube or pipe 4
is closed by a cork, plug, or screw cap. In order to prevent the damping liquid
escaping between the edge of the saucer or dish 2 and the box 1, the edge
of the saucer or dish is caulked with cement or putty 5, or the upper edge of
the box 1 can be spun or turned over the edge of the saucer or dish 2. This
caulking of the edge of the saucer or dish 2 prevents the damping liquid per-
meating through any other part of the saucer or dish 2 than is contiguous to the
centre of same, so that the edge of the box remains dry.
In Fig. 4 the box 1 is provided with a ledge 7 on which a layer of white lead is
laid, after which the saucer or dish 2 is placed in position and caulked with putty or
cement 5.
The blacking, or other substance is placed in the disc or saucer 2 and the
damping liquid permeates such dish or saucer 2 and maintains the blacking in a
moist condition. The height of the damping liquid in the waterspace 3 is at a
higher level than the centre of the dish or saucer 2 and the consequent tendancy is
for the liquid to find its way to the blacking or other substance.
The box 1 can be covered by a detachable lid or cover 6.
Having now particularly described and ascertained the nature and object of my
said invention, and in what manner the same is to be performed I declare that
what I claim is :-
(1.) The improved box as herein described in which is combined a porous dish
or saucer, a water space, and a tube or inlet way for the purpose herein described,
and as illustrated by Figs. 12 and 4 of the annexed drawings.
(2.) A box such as 1 having a porous saucer or dish 2, and a water space 3,
the upper and outer edge of the box and dish or saucer being rendered impervious
to water, as and for the purpose herein described, and substantially as illustrated
by Figs. 1. 2 and 4 of the annexed drawings.
