ALICE MARIA TASMAN and CHARLES HENRY TASMAN, both of 40, Baltic Street,
Golden Lane, in the County of London, Packing Case Manufacturers, do hereby
declare the nature of this invention to be as follows:-
The object of our invention is to provide means for locking the joints of the
wood used in making packing cases thereby strengthening the case and preventing
any part thereof being opened without breaking the wood between the joints, and
to carry our invention into effect we construct our improved locked joint as
follows;
-
When the pieces of wood abut in line such as the several widths used for the
top sides and bottom the joints are locked by inserting across each joint at each
end a piece of hoop iron preferably about three inches long straight with ends
about half an inch bent at right angles inwards these are either inserted in the
end grain of the wood half in each piece across the joint in saw cuts made for
the purpose of receiving them or may be simply driven in with a hammer in soft
wood without the saw cuts. When these pieces of metal are inserted flush with
ends of each pair of boards a nail is driven through the wood and iron locking
piece on each side of the joint into the box end which prevents the locking piece
being removed and when these are inserted and nailed at each joint all round the
case it is impossible to remove any part without splitting or breaking the wood
between the locked joints. For the corners where the lid or top and bottom join
the sides the iron locking pieces are similar in shape to the locking pieces described
but are bent at right angles in the centre so that they form corner pieces which are
let in or driven in and nailed through in the same manner as the straight locking
pieces.
Various modifications may be made the locking pieces may have the pieces
turned over at each end omitted and be simply straight pieces for ends in line and
right angled pieces for the corners nails being put through at each side of the
joint as described any suitable metal may be used but we prefer to use hoop iron as it
is cheap and effective.

formed, to be particularly described and ascertained in and by the following
statement;

locking piece on each side of the joint into the box end which prevents the locking

In the accompanying drawings Figure 1 represents the abutment of 2 pieces of
wood in line upon the top bottom or sides of a packing case. A and B are the two
pieces forming part of top, bottom or sides and C the end of the case D is the
piece of hoop iron driven in flush and E E dotted lines showing how the nails pass
through the top bottom or sides into the ends through the hoop iron.
Fig. 2 is a similar drawing showing a similar part, but in this instance the hoop
iron is straight without return ends. Figs. 3 and 4 show the two foregoing locking
pieces but bent at right angles for locking the corners of cases.
Similar letters denote corresponding parts in all the drawings.
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
The use in combination with wood packing cases of pieces of hoop iron or other
suitable metal strips inserted across the ends of the joints and having nails or
screws through them substantially as herein set forth and illustrated in the accom-
panying drawings.
