Improvements in Tins Suitable for Distributing Powders.
We, BRYANT & MAY, LIMITED, Manufacturers, and ARTHUR EVANS THORP,
Accountant, both of Fairfield Works, Bow, in the County of Middlesex, do
hereby declare the nature of this invention to be as follows:-
It has before been proposed to fix to the circumference of the body of the
tin strips projecting radially inwards and to provide rows of holes in the lid
which when the lid is suitably turned can be brought over either the strips
or the spaces thus closing or opening the holes.
It has also been proposed to arrange the holes in such a manner that no two
holes of different rows shall be on the same diameter of tin so that the holes
of one row may be opened whilst the holes of the other row or rows are closed.
Such a construction however is objectionable as the inwardly projecting strips
render it difficult to fill the tin.
According to this invention this objection is overcome by dispensing with
the strips fixed to the body and by making the lid double the inner part having
in it holes or slots corresponding to the holes in the outer part.
The two portions of the lid are pivotted together by a central pin, by turning
the edge of the outer part over a flange on the inner part or otherwise.
A stop is also provided to limit the movement of the parts relatively to each
other. This stop may conveniently take the form of a pin or projection on one
part working in a slot or groove in the other part or a pin on the body engaging
with slots of different widths in the two parts.

ing statement:-
It has before been proposed to fix to the circumference of the body of the
tin strips projecting radially inwards and to provide rows of holes in the lid
which when the lid is suitably turned can be brought over either the strips
or the spaces thus closing or opening the holes.
It has also been proposed to arrange the holes in such a manner that no two
holes of different rows shall be on the same diameter of tin so that the holes
of one row may be opened whilst the holes of the other row or rows are closed.
Such a construction however is objectionable as the inwardly projecting strips
render it difficult to fill the tin.
According to this invention this objection is overcome by dispensing with
the strips fixed to the body and by making the lid double the inner part having
in it holes or slots corresponding to the holes in the outer part.
The two portions of the lid are pivotted together by a central pin, by turning
the edge of the outer part over a flange on the inner part or otherwise.
A stop is also provided to limit the movement of the parts relatively to each
other.
Figure 1 is a plan, Figure 2 a side elevation, and Figure 3 a vertical section
of a lid constructed according to this invention. Figures 4 to 6 are inside
views of the lid showing the two parts in different positions.
The lid made of two metal sheets a and b pivotted together by the edge a of
the outer sheet a being turned over a ridge or bulge 61 formed around the inner
sheet 6. The turning movement of the two parts relatively to each other is
limited by segmental depressions a² 2 formed in them which fit one within
the other but are of different sizes. Two rows of holes a³ at are formed in the
outer part a and slots 63 in the inner part b.
In Figure 4 the parts are in one extreme position the lower side of the left
hand depression a² being in contact with the lower side of the depression b².
In this position all the holes a³ at are covered.
In Figure 5 the parts are in the middle position and the holes a³ are open
but a are closed.
In Figure 6 the parts are in the other extreme position the upper side of
the left hand depression a² being in contact with the upper side of the depres-
sion 6. In this position all the holes a³ at are open. The lid is prevented
from turning on the box by a depression 64 formed in its inner part 6 which
fits into a corresponding depression c in the box.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
-
1. A double lid formed of two parts pivotted together and having in them
holes or slots so arranged that by turning the parts relatively to each other the
total area of the apertures in the lid can be graduated substantially as described.
2. Double lids substantially as described and illustrated in the drawings.
