Improvements in Boxes and Canisters,

Improvements in Boxes and Canisters,
I, WILLIAM RIGHTER COMINGS, Mechanical Engineer, of Wandlemere, Riverside
Road, Summers Town, London, S.W., in the County of Surrey, do hereby declare
the nature of this invention to be as follows:
My improvement consists in providing boxes and canisters with duplex tops or
bottoms or both. To simplify the description, I will first describe the improve-
ments as applied to the bottom construction of a box or canister. One bottom piece
or lid is fitted to the inner surface of the body, and either fixed in its proper
position or fitted so as to be adjustable, the second bottom or lid is fixed or fitted
to the outside of the box or canister body, the space between the two bottoms or
lids is for some requirements left as an air space, for others is filled with material
suitable for securing the two bottoms or lids, or protecting the contents. In some
cases, I fill this space with non-conducting, insulating or waterproofing or other
desirable materials. Where desirable, the top of the box is constructed in the same
or a similar manner.
The advantages of these improvements are-1st. The duplex ends render the
box or canister stronger and at the same time serve to better secure the contents
from leaking or sifting out. 2nd. The employment of the inner lid or lids enables
the holding capacity of the box to be adjusted without changing the outside size
or appearance of the box or canister.

Improvements in Boxes and Canisters.
I, WILLIAM RIGHTER COMINGS, Mechanical Engineer, of Wandlemere, Riverside
Road, Summers Town, London, S.W., in the County of Surrey, 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:
-
My improvement consists in providing boxes and canisters with duplex tops or
bottoms or both.
To clearly explain my invention reference is made to the accompanying drawings
in which are shown various views of the parts when employing my invention in
making a box or canister of cardboard or other material for holding substances
which are to be "sifted" therefrom.
In such drawings Fig. 1 is a sectional elevation of the outer lid, Fig. 2 a like
view of the inner lid and strengthening piece, Fig. 3 the box or canister body in

page_text: section, Fig. 4 the inner bottom and stiffening piece in section, Fig. 5 the outer
bottom in section, Fig. 6 the parts when assembled and Figs. 7 and 8 plan views of
the outer and inner covers respectively.
The inner bottom piece a is fitted to the inner surface of the body c and either
fixed in its proper position as shown in Fig. 6 or fitted so as to be adjustable say in
the reverse position as indicated by dotted lines in said figure. The second or
outer bottom b is fixed or fitted to the outside of the box or canister body in the
usual way, the space if any between the parts a and b is for some requirements
left as an air space, for others is fitted with material suitable for securing the two
bottoms or protecting the contents. In some cases, I fill this space with non-
conducting, insulating or waterproofing or other desirable materials. Where de-
sirable, the top of the box is constructed in the same or a similar manner and in
Figs. 2 and 8 the inner lid d is shown provided with perforations in the same con-
centric line as similar perforations in the outer lid e. The inner lid d being secured
or held by friction in the body or casing c the outer lid is shown as pivoted thereon
by a tubular rivet or pin f closed at the bottom.
The advantages of these improvements are 1st. The duplex ends render the box
or canister stronger or permit a thinner body material than usual for a given
strength to be employed and at the same time serve to better secure the contents
from leaking or sifting out. 2nd. The employment of the inner tops and bottoms
enables the holding capacity of the box to be adjusted without changing the out-
side size or appearance of the box or canister.
I am aware that it is not new to make a box or canister having two compart-
ments between the extreme ends and I do not broadly claim such construction
but-
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improvements in boxes or canisters consisting in providing the body
portion with internal as well as external bottoms or lids, substantially as described.
2. The improved box or canister substantially as hereinbefore described and
as illustrated in the accompanying drawings.
Dated the 18th day of December 1897.
