page_text: Improvements relating to the Lids of Packing Boxes.
1, ANDREW KINROSS, 18, Elder Street, Edinburgh, Printer, do hereby declare
the nature of this invention to be as follows:-
The object of my invention is to enable the lids of packing boxes to be secured
and reopened, time after time, without the damage to the box which results
from the ordinary style of fastening by nails.
To accomplish this object I form catches or clamps in the following manner : —
I take a piece of wire doubled in the shape of an elongated letter U, and at
a suitable distance between the doubled end and the two free ends, I fold both
the latter to about a right angle, so that the catch now takes the shape of a
letter of doubled wire. I then fold over the two points in the same direction
as the original doubled end, to about a right angle, regulating the length of
the folded-over points according to the thickness of the sides of the box. The
lid being first placed in position, I fix one or more catches or clamps on either
side of the box and one or more on the back. In fixing the catches or clamps,
the doubled end may be laid across the edge of the box with the free ends
pointing down the side of the box, and their two folded-over points turned in
towards same. In this position these two points are driven home into the
side of the box, and may be clinched or turned over on the inside of the box if
desired. The doubled ends of the catches or clamps then project across the
edge of the lid so as to hold it firmly in position on all sides except the front,
where it remains free to. be withdrawn. To prevent the withdrawal of the lid
when the box is in use, I employ preferably a loop-headed or T headed screw
having a sharp point which permits it to be screwed by the hand down through
the front edge of the lid into the thickness of the front side of the box. For
this screw any ordinary form of screw nail may be substituted. For greater
security the screw may be retained in position when screwed down, by the use
of a suitable hasp and padlock, with or without a staple as may be required,
or the screw may be omitted and the hasp, staple and padlock used alone.
While I preferably form the catches or clamps as above described, they may
also be formed of strap or hoop iron or other metal, bent in the shape of the
letter L. and permanently fastened to the sides or back of the box by suitable
nails or rivets.

lid being first placed in position, I fix one or more catch or clamp on either

the doubled end may be laid across the edge of the box with the free ends
pointing down the side of the box, and their two folded-over points turned in
towards same.
In this position these two points are driven home into the
side of the box, and may be clinched or turned over on the inside of the box if
desired. The doubled ends of the catches or clamps then project across the
edge of the lid so as to hold it firmly in position on all sides except the front,
where it remains free to be withdrawn. To prevent the withdrawal of the lid

the front edge of the lid into the thickness of the front side of the box. For

of a suitable hasp and padlock, with or without a staple as may be required,
or the screw may be omitted and the hasp, staple and padlock used alone.
While I preferably form the catches or clamps as above described, they may
also be formed of strap or hoop iron or other metal, bent in the shape of the
letter L. and permanently fastened to the sides or back of the box by suitable
nails or rivets.
Figure 1 represents the clamp ready for use, the piece of wire forming same
being first doubled at A A to form an elongated letter U, thereafter doubled
at B B, and finally doubled at C C. The lid being placed in position, I fix the
catch or clamp to the side of the box, so that the part from A to B projects
across the edge of the box and overhangs the lid. The points D D are then
driven home into the side of box.
Figure 2 represents a form of screw which may be used to prevent the lid
from being withdrawn, in manner previously described.
Having now particularly ascertained and described the nature of my said
invention, and the manner in which the same is to be performed, I declare that
what I claim is:
The construction of a catch or clamp formed in all or any of the alternative
ways hereinbefore described for use in conjunction with a retaining screw, pin,

the use of nails, all as described in the foregoing specification and illustrated in
the accompanying drawings.
