An Improved Method and Means of Locking the Lids or Covers on
"Lever Lid" Metal Cans and Cases.
I WILLIAM WOOLNOUGH of 3 Cranmer Road Forest Gate in the County of Essex
Tin plate Worker 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 an improved method and means of locking or firmly
securing the lids or covers on cans and cases of tin plate or other suitable metal of
the character known as "lever lid tius" that is caus in which an inner edge or rim is
provided at the top of the can on which inner edge the lid is placed the can being
opened by forcing up the lid by means of a coin or other lever placed under the edge
of the lid and having its fulcrum on the outer edge of the can or case.
Now my present invention consists in locking or securing such lids on such cans or
cases by means of a metal clip or metal clips (advantageously three in number or
more or less and which may be formed of tin plate or other suitable metal) which―
when the lid is placed in position on the can-are bent over and forced down to clip
the two edges thus locking the lid securely on the can until such clips are removed as
for instance by being forcibly bent back whereupon the lid can be opened in the usual
way as before described and if desired again secured by bending over and forcing
down the clips again.
The clips may be soldered rivetted or otherwise, formed mounted or secured in any
suitable manner on the bodies of said cans or on the lids or may be unattached and
separate from either so that they will bend over to secure the lid as above and may be
of any convenient shape.
And in order that my invention may be the more easily understood and readily
carried into practice I will proceed to further describe same with reference to the
accompanying sheet of drawings Fig. 1 of which shews a vertical sectional view of a
can and lid having my invention applied thereto.
Fig. 2 is a plan view of the top of the can or case with the lid secured by three of
my clips."
"
Figs. 3 and 4 shew "local" views of a different arrangement of the clips and Fig. 5
shows the "separate" clip.
Referring to Figs. 1 and 2, a is the side or body of the can and 6 is the inner edge
or rim formed and arranged thereon and c is the lid or cover fitting tightly on the
ledge b as is well understood.
d, d are the clips which in this case are soldered on to the outer edge of the
side or body of the can a itself and take the position shewa in dotted lines in
Fig. 1.
When the lid c is placed in position the clips d are forced down (in the direction
shewn by the arrows) from about the positions shewn in dotted lines to the position
shewn in black lines Fig. 1, and thus securely lock or hold down the lid c, and this
arrangement of the clips will be found very advantageous.
Fig. 3 is a local sectional view in side elevation and Fig. 4 is a local plan shewing
the "clip" & secured on the lid c and bent outwards over the outer edge of the side
of the can to lock the lid con the can, a projection such as that known as a
"double
seam" being provided on the top outer edge of the cam to give the required hold to
the clip.
Fig. 5 is a view of a clip d formed (of any suitable metal) separate and unattached
to either the lid or side of the can such clips being placed over the lid edge and the
side of the can and there closed or pinched tightly-by any suitable means such as
pliers" or squeezing tongs-to lock or hold the two parts together.
x is a handle-which may be of any convenient form-attached to the lid c.

page_text: 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 clip d for locking or securing the lid or cover on "lever lid "metal cans and
cases substantially in the manner and for the purposes herein before described and
illustrated in the Drawings annexed
2. The improved method of securing or locking the lids on "lever lid" metal
cans and cases substantially in the manner and for the purposes herein before set
forth.
