Complete Specification Left, 8th Aug., 1888
Complete Specification Accepted, 14th Sept., 1888
We, WILLIAM CRAWFORD, and CORNELIUS CRAWFORD, of 49 Arlington Street,
Glasgow, in the County of Lanark, North Britain, Tinsmiths, do hereby declare the
nature of this Invention to be as follows, that is to say:
Our said Invention relates to metallic boxes, cans, or similar receptacles, of the kind
in which, for the purpose of securing tightness of the lid without solder, a stamped
ring is soldered to the edge of the body of the receptacle to receive the lid which is
also stamped.
In carrying out our Invention we make the ring with a conical or bevilled outer
part, its wider part fitting upon the edge of the body. In one modification the inner
part of the ring is turned inwards from the smaller edge of the conical part to form a
nearly cylindrical flange, and the inner edge of this flange may be stamped with a very
narrow lip extending towards the centre or slightly outwards. The lid is stamped with
a nearly cylindrical part to fit the nearly cylindrical flange of the ring. The outer
edge of the lid is piped or turned over to form a rounded projecting part to bear
against the most projecting part of the ring. In another modification the nearly
cylindrical flange of the ring is made to extend outwards instead of inwards from
the conical part. Receptacles made in the improved manner can be opened by striking
with any convenient instrument such as the back of a knife against the underside
of the rounded projecting part of the lid.
Dated this Seventh day of November 1887.

We WILLIAM CRAWFORD, and CORNELIUS CRAWFORD, of 49 Arlington Street,
Glasgow, in the County of Lanark, North Britain, Tinsmiths, do hereby declare the
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,
that is to say :-
Our said Invention relates to metallic boxes, cans, or similar receptacles, of the
kind in which, for the purpose of securing tightness of the lid without solder, a
stamped ring is soldered to the edge of the body of the receptacle to receive the lid
which is also stamped.
In carrying out our Invention we make the ring with a conical or bevilled outer
part, its wider part fitting upon the edge of the body. In one modification the inner
part of the ring is turned inwards from the smaller edge of the conical part to form a
nearly cylindrical flange, and the inner edge of this flange may be stamped with a
very narrow lip extending towards the centre or slightly outwards. The lid is stamped
with a nearly cylindrical part to fit the nearly cylindrical flange of the ring. The outer
edge of the lid is piped or turned over to form a rounded projecting part to bear against
the most projecting part of the ring. In another modification the nearly cylindrical
flange of the ring is made to extend outwards instead of inwards from the conical part.
Receptacles made in the improved manner can be opened by striking with any con-
venient instrument such as the back of a knife against the underside of the rounded
projecting part of the lid.
Boxes made according to our Invention are shown on an accompanying sheet of
explanatory drawings figures, 1, 2, and 3, being vertical sections showing one modi-
fication and figures 4, 5, and 6, vertical sections showing the second modification.
Figures, 1, and 4, represent the boxes complete as closed with their lids, L;
figures, 2, and 5, show the lids, L, separately; and figures, 3, and 6, show separately
the rings, R, into which the lids, L, fit. The lids, L, and rings, R, being stamped with
accurately shaped dies fit accurately together; and the rings, R, are soldered upon the
bodies, B, of the boxes. By our Invention the rings, R, are made of the improved
forms shown, these forms being such as to impart great strength and rigidity and
insuring the tight fitting of the lids, L, in their places.

page_text: Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1 Making metallic boxes, cans, or similar receptacles, with stamped rings for
receiving the lids or covers such rings being of the improved form shown in figures 1,
and 3, of the accompanying drawings and hereinbefore described.
2-Making metallic boxes, cans, or similar receptacles, with stamped rings for
receiving the lids or covers such rings being of the improved form shown in figures, 4,
and 6, of the accompanying drawings and hereinbefore described.
