I carry out my invention in the following manner viz: The two ends of the box,
are formed of wood, with vertical grooves into which the plates slide in such a
manner that the surfaces may not touch or injure each other."
The sides, bottom, and lid are formed of cardboard, strawboard, or such like
material, and are attached to the wood ends with glue, or in any convenient
manner.
The aforesaid wood ends are hollowed out at the top inside edge with a circular
cutter (see A), to expose the corners of the plates for lifting them out.
When required clamp and fix a metal strip of the angle shown (B) on the top.
edge of wood ends, to prevent warping-and also fix a strip of metal along the
bottom edge of wood ends (C) outside the cardboard bottom, to give additional

My improvement consists in combining wood and cardboard, millboard, or such
like material, strengthened with metal plates, in the construction of boxes for the
aforesaid purpose the combination as carried out in my invention forming a

I carry out my invention in the following manner-
The two ends of the box are formed of wood, with vertical grooves into which
the plates slide, in such a manner that the surfaces may not touch or injure each
other this I accomplish by making each groove to take two plates, which are
placed back to back.
The sides, bottom, and lid of box are formed of cardboard, millboard, or such
like material, and are attached to the wood ends with glue and sprigs, or in any
convenient manner,
The aforesaid wood ends are hollowed out at the top inside edge (see A) with a
circular cutter, to expose the corners of the plates for lifting them out.
When required I clamp and fix a metal strip of the angle shown (B) on the top s
edge of wood ends, to prevent warping and also fix a strip of metal or wood along
the bottom edge of wood ends (C) to give additional strength to the bottom, and
support each end of the plates.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1-The combination of wood and cardboard, millboard, or such like material.
