Improvements in Appliances for Strengthening the Corners of Boxes
and the like.
I, CHARLES ARTHUR KIRKBY, of 123, Arundel Street, City of Sheffield, Cabinet
Case Manufacturer, do hereby declare the nature of my invention to be as
follows:
My invention relates to an appliance for strengthening the corners of boxes,
cutlery cases and the like, and the method of using same."
It consists of a triangular piece of flat metal, say for example brass, having
two pins preferably made from the same continuous piece of metal, projecting
from its longest edge, the other edges being at right angles, to coincide with
the outer sides of the box or other case.
A sawgate is made horizontally in the two parts which form the mitre or
corner of the box to receive the triangular brass plate, which is not in position
until the pins or projecting spikes are driven into the wood. There may be
more than two of the pins or spikes if desired, and they may be curved or bevelled
on one side to cause them to diverge either inwards or outwards, to bind more
firmly into the woodwork of the box.

Improvements in Appliances for Strengthening the Corners of Boxes
and the like.
I, CHARLES ARTHUR KIRKBY, of 123, Arundel Street, City of Sheffield, Cabinet
Case Manufacturer, 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:―
My invention relates to an appliance and its use for strengthening the corners
of boxes, cases for cutlery and like cases.
The appliance and its use, is shown in the accompanying sheet of drawings,
similar letters referring to similar parts in any of the several figures.
Fig. 1, shows flat and edge views of the appliance.
Fig. 2, the corner of a case prepared for the appliance.
Fig. 3, sectional plan of same with the appliance in position to be driven home.
Fig. 4, similar view with appliance driven home.

page_text: The appliance or corner piece A, I prefer to make from a flat piece of sheet
brass by cutting it therefrom, but it may be made from other material and by
other means if preferred.
It is provided with two or more spikes B, which project from its inner edge
to the desired extent, and are intended to penetrate the wood of which the box
or case E is made.
The angular recess C, is cut out to match the angle of the inside of the case E,
but if the appliance is made smaller in proportion to the case it may be omitted.
The pins or spikes which are preferably made from the same continuous piece
of metal, may be curved or bevelled on one side so as to cause them when being
driven into position, to diverge in either direction, and thus to grip the wood
and more firmly secure the appliance and the corners of the case.
In applying the corner piece, I take the case and make a sawgate D, as shown
in Figs. 2 & 3, or as many as may be desired; in this case it is shown as cut
through the corner into the box, but this is not of necessity.
I then take one of the corner pieces A, and place it within the sawgate to
which it corresponds, as shown in Fig. 3, and by any suitable means I force
the spikes or pins B, into the woodwork or into holes prepared for them, until
the outside edges of A, are level with the face of the case, as shown in Fig. 4.
To give an additional grip upon the woodwork of the case, I may make per-
forations through the appliance into which the wood will expand to some extent.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, -I-declare_that_ what I
claim is:-
-
1-The improved appliance for strengthening-the-corners-of-boxes, cases and
the like, hereinbefore described.
2-As a means for strengthening the corners of boxes and cases, a metallic
corner plate A, provided with spikes such as B, and used in the manner as
herein before described and illustrated in the annexed drawings.
Dated the 13th day of July 1899.
