Method of Securing same in Position.
I JOHN GEORGE HORSEY of The Elms Catford, in the County of Kent, Gentleman
do hereby declare the nature of this invention to be as follows:
My Invention refers to the joining together of the sides and ends of boxes made
of cardboard, paper, or other like substances by means of corner pieces formed of
metal or other suitable material preferably metal such as zinc or brass. To form
such corner I take a piece of sheet metal and double or fold it across its centre
bringing the two surfaces almost into contact-that is leaving sufficient space between
to enable the thickness of cardboard or paper to be afterwards inserted-I then
again bend, in a line directly across the former bend, the piece of metal to a right
angle with equal or unequal sides and slip it down over the corner of the box
embracing the cardboard between the metal, and, by means of pressure, indent or
pierce the two arms of the metal corner piece so that it grips or adheres to the
cardboard and thus forms a neat and strong corner to the box-If the material be
other than metal these corner pieces may be gummed glued or cemented upon the
insides so that when wetted prior to or during their application to the cardboard they
will adhere thereto, and so dispense with the indenting as before referred to―The
corner pieces as lastly described may be waterproof on the exterior.
Dated this Thirty first day of January 1887.

An Improved Corner-piece for Cardboard and like Boxes and
Method of Securing same in Position.
I JOHN GEORGE HORSEY of The Elms, Catford, Kent, Gentleman, do hereby
declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement—
My invention refers to the joining together of the sides and ends of boxes made
of cardboard, paper or other like substances by means of corner pieces formed of
metal or other suitable material, but preferably metal, such as zinc or brass.
To form such corner I take a piece of sheet metal and double or fold it across its
centre bringing the two surfaces A. B. almost into contact as at Figure 1, that is
leaving sufficient space between to enable the thickness of cardboard or paper to be
afterwards inserted. I then again bend in a line directly across the former hend the
piece of metal to a right angle as at Figure 2 with equal or unequal sides and slip it
down over the corner of the box embracing the cardboard C between the metal as at
Figures 3 and 4 by means of pressure indent or pierce the two arms of the metal
corner piece so that it grips or adheres to the cardboard and thus forms a neat and
strong corner to the box.
The punctures by the press or other appliance may make the edge of the puncture
somewhat rough as at Figure 5 to firmly bind the corner piece in close contact the
distance of said punctures from the edge of the angled side C preventing the corner
picce tearing away.
The punctures may be of round or other shape or in the form of long slits D.
If the material be other than metal these corner pieces may be gummed glued or
cemented upon the insides and moulded to shape so that when wetted prior to or
during their application to the cardboard they will adhere thereto and so dispense
with the indenting as before referred to.
The corner pieces as lastly described may be waterproof on the exterior.
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
The manufacture and employment of metal or like corner pieces, double folded
as shown at Figure 2 of the annexed drawings for cardboard and like boxes as
described.
