Improvements in the Mode of and Means Employed for Securing
the Lids or Covers of Packing and like Cases.
We, ALFRED WATSON of No. 8 First Avenue, Bush Hill Park, Enfield, in the
County of Middlesex, Electrical Engineer, and KOBERT JOSEPH HOOPER-RASTRICK
of No. 30 Lavender Gardens, Lavender Hill, Wandsworth in the County of Surrey,.
Gentleman, do hereby declare the nature of this invention to be as follows:-
Our invention relates to an improved means for securing and removing the lids or
covers of packing and other cases.
the lids
Much time, labor and money is sacrificed in packing and unpacking cases,
or covers of which are secured by nails or screws. To obviate these disadvantages
and with a view to ensure greater durability to packing cases, we proceed as
follows, that is to say :- -We stamp, cut, cast or otherwise form from suitable soft or
malleable metal, as for instance manganese steel, corner pieces shaped somewhat like
an inverted T the ends of the horizontal limbs being bent over and pointed. In
adapting the corner-pieces to a packing case, the horizontal limbs are bent round the
corner of the case and the points forced into the case by hammering or other means,
thus effectively securing them thereto without the employment of nails or screws and
therefore without injury to the case.
The lid or cover having been placed in position, the vertical limb of the device,
with which three of the corners are provided, are turned over and made flat with the
surface, the fourth corner being secured by preferably a screw; and, in order to
reduce the injury to the case caused by frequent screwing and unscrewing, we employ
a flat perforated headed nail or screw, the head being bent at right angles thereto.
This nail is forced into, say, the end of the case, so as to allow the head thereof to lap
over and enter a recess formed in the adjoining side. We may also employ a small
perforated plate of metal inserted in the lid or cover in a position corresponding with
the perforated head of the nail aforesaid.
By the adoption of the above means the woodwork is materially strengthened,
inasmuch as the screw for securing the lid or cover passing primarily through metal,
the risk of straining and cracking of the wood is reduced to a minimum.
Instead of the corner pieces being formed in the manner above described, we may
employ wire, in substitution thereof, of sufficient tensile strength, and so bent that the
centre may lap over the corner of the case, the ends being pointed and forced into the
sides and ends thereof.
From the foregoing it will be seen that on the removal of the one screw employed,
the lid or cover may be withdrawn without trouble, and without the slightest injury
to either case or lid.

Improvements in the Mode of and Means Employed for Securing
the Lids or Covers of Packing and like Cases.
We, ALFRED WATSON of No. 8 First Avenue, Bush Hill Park, Enfield in the
County of Middlesex, Electrical Engineer, and ROBERT JOSEPH HOOPER-RASTRICK
of No. 30 Lavender Gardens, Lavender Hill, Wandsworth, in the County of Surrey,
Gentleman, 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, reference being also had to the accompanying sheet of
drawings in which :-
Figures 1 and 2 represent two methods which we employ for partly securing the
lids or covers of packing cases.
Figure 3 shows a portion of a packing case having a perforated headed. nail sunk in
or adapted to the corner, and
Figure 4 shows a portion of a lid or cover having a perforated metal plate inserted
in the corner for the reception of a screw.
Figures 5 and 6 are types of corner clamps;
Figure 7 is the perforated headed nail, and
Figure 8 the perforated plate all drawn to enlarged scale.
Our invention relates to an improved means for securing and removing the lids or
covers of packing and other cases.
Much time, labor and money are sacrificed in packing and unpacking cases, the lids
or covers of which are secured by nails or screws. To obviate these disadvantages and
with a view to ensure greater durability to packing cases, we proceed as follows, that
is to say: We stamp, cut, cast or otherwise form from suitable soft or malleable
metal, as for instance manganese steel, corner pieces a shaped somewhat like an
inverted T, thus 1, Figures 1 and 5, the ends of the horizontal limbs 6 being bent
over and pointed. In adapting the corner pieces to a packing case, the horizontal
limbs bare bent round the corner of the case and the points forced into the case B, as
shown in Figure 1, by hammering or other means, thus effectively securing them
thereto without the employment of nails or screws, and therefore without injury to
the case.
The lid or cover having been placed in position, the vertical limb c of the device,
with which three of the corners are provided, are turned over and made flat with the
surface, the fourth corner being secured by preferably a screw; and, in order to
reduce the injury to the case B caused by frequent screwing and unscrewing, we
employ a flat perforated head nail or screw d, Figures 3 and 7, the head being bent
at right angles thereto. This nail is forced into, say, the end of the case, so as to
allow the head thereof to lap over and enter a recess formed in the adjoining side.
We may also employ a small perforated plate of metal e, Figures 4 and 8, inserted
in the lid or cover A in a position corresponding with the perforated head of the
nail e aforesaid.
By the adoption of the above means the woodwork is materially strengthened,
inasmuch as the screw for securing the lid or cover, passing primarily through metal,
the risk of straining and cracking of the wood is reduced to a minimum.
Instead of the corner pieces being formed in the manner above described and shown
in Figures 1 and 5, we may employ a staple of wire in substitution thereof, of
sufficient tensile strength, and, as in Figure 6, so bent that the centre may lap over
the corner of the case A, the ends being pointed and forced into the sides and
ends thereof, as shown in Figure 2.
From the foregoing it will be seen that on the removal of the one screw employed,
the lid or cover may be withdrawn without trouble, and without the slightest injury
to either case or lid.

page_text: 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 improved means for securing the lids or covers of packing cases substantially
as described and shown.
