I WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6 Lord Street Liverpool, in the County of Lancaster, and
323 High Holborn in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said invention for "IMPROVEMENTS IN METALLIC BOXES
RECEPTACLES FOR HOLDING ALIMENTARY AND OTHER SUBSTANCES," (a communi-
cation from abroad by Emile Picard of Brussels in the Kingdom of Belgium
Engineer) to be as follows:-
OR
This invention has for its object a cylindrical "tin" or other metal box and lid
constructed in such manner that when the lid is down on the box a sunken bead
or groove in the box allows room and a fulcrum or abutment for a lever to be used
to raise the box lid or cover, and so that no amount of side crushing shall separate
the bottom from the box and yet both bottom and lid are put on and held without
solder.
The bottom of the box is formed with a rim or flange pointing downward and
having a slightly conical increase to the bottom; the sides of the tin are also
formed slightly conical outward at bottom and of a size to just fit over the conical
bottom when the latter is pressed in and project its depth beyond it. The
projecting sides are now doubled over the bottom flange and thus form an
impervious solderless joint.
A short distance from the top, the box is deeply grooved, inward all round so as
to present a rather sharp and nearly rectangular turn both above and below the
groove, and the part above is made slightly conical inwards to the top. The lid is
formed slightly conical, the reverse way to fit over the top of the can, and its edge
is armed with a bead, that when the lid is pressed firmly down just allows of a thin
blade or plate such as a coin being inserted between it and the lower edge of the
groove. The consequence of this arrangement is, that as with the bottom the two
conical parts pressed one into another form an impervious fit, while the joint can
at any moment be severed by inserting a lever into the nick or groove and prising
the lid up. If however it be wanted to make the lid extremely tight this can be
done by pressing or turning the bead of the lid into the groove in the box. It will
now require great force to loosen the lid, and the latter having been forced down
over the cone of the box, and then bent inward, will be oil and water tight,
without solder, forming a joint very similar to the bottom.

improvements in mean DOXES OF Receptacles for moving
Alimentary and other Substances.
I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool in the County of Lancaster, and
323 High Holborn, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of this invention (a communication from abroad by Emile Picard of
Brussels, in the Kingdom of Belgium, Engineer) and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention has for its object a cylindrical "tin" or other metal box and lid
constructed in such manner that when the lid is down on the box a sunken bead
or groove in the box allows room and a fulcrum or abutment for a lever to be used
to raise the box lid or cover, and so that no amount of side crushing shall separate
the bottom from the box, and yet both bottom and lid can be put on and held
without solder.
The invention is best set forth by giving an illustration which I do in the
accompanying drawing in which-
Figure 1 is a section of a tin complete.
Figure 2 a similar view of each part separate as they are, after being completed
together.
Figure 3 sketch of alternative joint for bottom.
In these A is the body of the tin. B a top added, these two could both be in
one, but for the joint of body which would prevent the lid from fitting or wedging
perfectly tight, these two soldered together also form a very firm abutment as
hereafter set forth. Top B is made very slightly conical as shown. D is the
bottom. This is turned or hooked under the lower edge of the body, and then
both it and the body are beveled out slightly, conical, say about a sixteenth of an
inch to the foot, the bevel is exaggerated in the drawing to be observable to
prevent the bottom being forced in or upward and to form an impervious joint.
If desirable, the body can be hooked round the bottom as set forth in Figure 3
instead of the bottom being hooked round the body, but I prefer the former
arrangement. E is the lid also made slightly conical to fit tightly on B with
space to spare between B and the top to allow for wear and repeated forcing down
of the lid. This lid has a stout rim F turned on it, so that when in position a
lever with its end inserted in groove C can be used to prise off the lid.
double thickness of groove C greatly assists the lever in obtaining a firm hold or
fulcrum in the groove.
.
The
The advantage of this arrangement of lid and top of box is, that the two conical
parts pressed one into another form an impervious fit, while further the joint can
at any moment be severed by inserting a lever into the nick or groove and prising
the lid up.
If however, it be wanted to make the lid extremely tight, this can be
done by pressing or turning the bead of the lid into the groove in the box. It
will. now require great force to loosen the lid, and the latter baving been forced
down over the cone of the box, will be oil and water tight, without solder.

page_text: It will be obvious that a bead on the box will perform the same function as
groove C, but it is more clumsy, and causes the box to take more room.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is
1st. The improvement in metallic cans, boxes or receptacles for holding ali-
mentary and other substances which consists in forming the bottom joint conical,
and the one part, bottom, or body hooked round and embracing the conical part of
the other on both sides, substantially as described.
2nd. The further improvement which consists in forming the upper part of the
body, and the flange of the lid slightly conical, and grooving or beading out the
body, so that a coin or other thin article can be inserted in said groove and used
as a lever to raise the lid, substantially as described.

3rd. The combined improvements in boxes or receptacles substantially as and
for the purposes herein described.
