An Improved Packing Case or Box.
I, THOMAS OVERGAARD of Sydney in the Colony of New South Wales, Agent and
Importer, do hereby declare tho nature of this invention and in what in inner the saine
is to be performed to be particularly described and ascertained in and by the following
statement:
This invention has been devised in order to produce a strong convenient and cheap
case or box in which may be packed and transported all kinds of chattels merchandise,
and specially bulk goods. This packing case or box is so constructed that it may be
easily taken apart for transmission as an "empty" and will then occupy but little
space.
This improved packing case is constructed by binding the contiguous or adjacent
edges of the sides and ends or some of them with a peculiarly notched or slotted
material so that when said sides and ends are placed together the notched or slotted
binding material over the edges forms straps and alternating knuckles of hinges at
the corners through which hinges spirals rods or pins are twisted or inserted and
firmly fasten the sides and ends of the case or box into one whole. The sides and
ends with the binding hinge-forming material thereon might be used to construct
cases or boxes of any convenient shape although I prefer to construct cases of
parallelopiped form in which case it is only necessary to have the binding material or
hingo at eight of the twelve corners or angles. I also prefer that this binding hinge-
forming material should be strong enough to connect together two or more pieces to
form one end or side.
But in order that this invention may be clearly understood reference will now be
made to the drawing herewith in which Figure 1 is a perspective view of a packing
case or box constructed according to this invention while on a larger scale Figures 2,
and 3, and 34 shew respectively part elevation and sections of one of the corners or
angles of the same. Figure 4 shows binding material flattened out.
Å A are the sides and ends and B the binding material thereon-0 are spiral
fastening pins-B' are angular notches or slots-B angular knuckle-forming part-
B nails or rivets. It is necessary that the angles with the corner or hinge at which
the notches or slots B' are cut should be the same as the angle or pitch of the spiral C.
In Figure 3 the binding material is shewn with two wings or flaps to take round the
edge of side or end to which it is attached while in Figure 34 it has but only one
which is fastened to the outer edge of the side or end of the box.
In constructing a packing case or box such as that shewn and its size having been
previously determined I take the pieces of board or other material which are to be
joined to form a side or end and around the edges 1 nail or rivet the binding hinge-
forming material. This hinge-forming material is supplied in the form of strips of
metal say galvanized or plain iron tin zinc copper brass &c. from the centre of
which two contiguous diamonds or angularly set parallelograms have been notched or
slotted cut or stamped at regular distances apart each said distance being preferably
just slightly shorter than the length of the notched or slotted part. The sides and
ends having been thus bound on their edges and placed together when the alternating
and intergeared angular knuckles B' of the binding materials are formed into a hinge
or a fixed corner by insorting fastening spiral C which spiral is inserted by being
twisted or revolved and finds its way through the knuckles B and draws them
together making a female screw or helix of them. These fastening spirals being
made of metal or such like material have sufficient spring to allow them to be easily
threaded through the knuckles and they are retained in place after threading by the
spiral or helical bed. The ends might be turned slightly over or carry a nut or key
to form a convenient revolving handle but they are preferably turned or revolved by

page_text: pliers or pincers taking over their ends. It will be seen that at four of the twelve
angles there is no binding or fastening but if required these angles or corners may
be fastened similarly to the others. Any one side or end of the case or box may then
be used as the cover one of its bound edges and the contiguous edge of the next side
or end forming its hinge and the fastening spiral parallel to the spiral of said hinge
being withdrawn allows the cover to open. The box may be easily taken to pieces for
transhipment as "empty" by withdrawing fastening spirals by revolving them say
by grasping their ends with a pair of pincers or pliers.
It is to be understood that I do not confine myself to any precise form or size of
which my improved packing case or box may he constructed nor to any precise
material or size or strength of any of its parts so long as the nature of my invention
be retained.
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 :-
First. An improved packing case or box formed of sides and ends whose contiguous
edgos or some of them are bound with angularly notched or slotted material forming
knuckles loops or hooks through which a spiral fastening pin is screwed or inserted
substantially as herein described and explained.
Second. The combination and arrangement with the sides and ends of packing
cases or boxes and upon the edges of said sides and ends of an angularly notched or
slotted binding strip forming spaced knuckles through which a spiral pin might be
screwed or inserted substantially as herein described and explained.
