PROVISIONAL SPECIFICATION.
Improvements in Openers for Boxes, Cases, and the like.
BENJAMIN DEAVILLE Beech House Beech Avenue Nottingham Manufacturing
Chemist do hereby declare the nature of this invention to be as follows:-
This invention, which relates to improvements in appliances used for the opening
of boxes, packing cases and the like, has for its object the construction of
openers which shall be more effective than the means generally used for the same
purpose.
According to this invention a wedge shaped piece is driven between the parts
to be separated, and means are provided for enabling the wedge to be used as
a lever.
In one arrangement the wedge is rigidly attached to the lever, at, or about at
right angles to the same. In another arrangement a hole or alot is formod in the
wedge and the end of the lever shaped to fit in the same, or the hole or slot may
be in the end of the lever, and the wedge shaped to fit therein. When a separate
lever is used, it may be employed for driving the wedge into position.
With any
of the above described arrangements the under side of the wedge may be provided
with a projection, or a fixed or hinged claw for pressing upon or into the side of
the box and form an additional support.
In another arrangement the wedge is made with a longitudinal opening through
which the end of the lever can be passed. This end of the lever is made to press
upon or into the side of the box and has a foot which presses on the end of the
wedge when the lever is moved from its vertical position. The end of the lever
may be slotted to pass over the wedge instead of through it.
In another arrangement, a wedge with a fixed or removable lever has a second
wedge pivotted to it. This second wedge is provided with a piece which extends
down the side of the box, and forms a stay to the fulcrum of the first mentioned
wedge.

Chemist 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 aud by the
following statement :--
This invention relates to improvements in openers or appliances to be used for
opening boxes packing cases and the like, the object of the invention being the
production of an opener which is simple and cheap in construction, and more
effective than other means generally used for the same purpose.
According to this invention, the opener comprises a wedge shaped piece for
driving between the case and its lid and a lever designed to be used with the wedge
P01

page_text: shaped piece. The lever may also be used as a hammer for driving in the wedge,
and may be provided with a claw for withdrawing nails.
In the accompanying drawings which illustrate this invention
Fig. 1 is an elevation and Fig. 2 a plan of an opener and its lever.
Figs. 3 and 4 are elevations of alternate forms of openers and levers.
In Figs. 1 and 2 which show the construction I preferably adopt, the piece for
driving between the case and its lid or for similar purposes is wedge shaped in
elevation between the end a and the part b, and from 6 to c the piece is tapered in
both directions to fit a similarly shaped hole in the end of the lever e. Beyond the
end of the part be there is a round or other conveniently shaped piece d somewhat
less in section than the section on the line cc so as to allow of the wedge being
forcibly driven without damage to the part b c.
с
The levere at its lower end is made with a socket which is shaped to fit the
end b c and on one side is provided with a head for striking the end d of
the wedge and a claw for drawing out the nails.
In Fig. 3 the wedge a to b, and the end d are the same as the similarly lettered
parts shown in Fige. 1 and 2. Between the parts b and c thero is a slot for the
reception of the wedge shaped end hk of the lever e.
In Fig. 4 the wedge a to band the end d are also the same as the similarly
lettered parts shown in Fig. 1 and 2. Between the parts b and c is a parallel
slot mn and at the top of the slots and on one or both sides of the same there
are corrugations o. The lover e for use with this wedge is made to pass easily
through the slot mn and its end is bent and tapered to an edge / so that it can
readily be pressed into the side of the case to be opened. The lever is also
provided with projecting pins p which are brought down into the corrugations o
when the lever is moved to wrench open the lid.
The wedges are preferably made from forged steel which may be tempered, and
the levers of cast steel or malleable cast iron.
Instead of making the levers solid they may be fitted with woodon handles
which may be attached to the socket or wedge shaped ends by any of the usual
meane.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. An opener for boxes, cases and the like constructed as herein described with
reference to Fige. 1 and 2 of the accompanying drawings.
2. An opener for boxes, cases, and the like constructed as herein described with
reference to Fig. 3 of the accompanying drawings.
3. An opener for boxes, cases, and the like constructed as herein described with
reference to Fig. 4 of the accompanying drawings.
Dated this 28th day of November 1895.
