PROVISIONAL SPECIFICATION.
A Material for use in the Manufacture of Boxes, Trunks,
and the like.
I, ERNST PAUL KRENKEL of 81 Bayersche Strasse Leipzig in the Empire of
Germany, Box Manufacturer, do hereby declare the nature of this invention to be
as follows:-
The object of this invention is to manufacture from certain materials as herein-
after stated, a material in sheets from which boxes, trunks, musical instrument
cases and the like may be conveniently made, and which shall possess great strength
and elasticity with a small amount of weight.
The body of the material is made of American poplar wood and on the one side
this is covered with sail cloth glued thereon and afterwards painted or varnished.
Before, or at the time of, affixing the sail cloth a number of half round slats are
fastened at intervals onto the side of the wood to be covered by the sail cloth.
These slats are placed across the line of the fibre of the wood and are made of
cane, preferably bamboo or malacca.
On the other side of the wood is first placed and fastened with glue a thin layer
of fibre such as manilla, coir or cochin fibre arranged crosswise to the line of the
fibre of the wood. Over this layer is fastened by glue thin China matting of
more or less ornamental nature, or in place of this matting, a matting woven of so
called Indian bast.
The whole is suitably pressed to secure the parts well together and from the sail
cloth side, which is intended to be the outside a number of wire staples or cramps
are driven through the whole and secured by turning over their ends on or in the
matting on the other sides. The staples or cramps may be of white metal or may
be nickeled with the object of preserving them from rust.
Dated this 5th day of April 1892.

COMPLETE SPECIFICATION.
A Material for use in the Manufacture of Boxes, Trunks,
and the like.
I ERNST PAUL KRENKEL of 81 Bayersche Strasse, Leipzig in the Empire of
Germany, Box 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 :-
The object of this invention is to manufacture from certain materials as herein-
after stated, a material in sheets, from which boxes, trunks, musical instrument
cases and the like may be conveniently made, and which shall possess great strength
and elasticity with a small amount of weight.
The body of the material is made of American poplar wood and on the one side
this is covered with sail cloth glued thereon and afterwards painted or varnished.
Before, or at the time of affixing the sail cloth, a number of half round slats are
fastened at intervals onto the side of the wood to be covered by the sail cloth.
These slats are placed across the line of the fibre of the wood and are made of cane,
preferably bamboo, or malacca.
On the other side of the wood is first placed and fastened with glue a thin
layer of fibre such as manilla, coir or cochin fibre arranged crosswise to the line

page_text: of fibre of the wood. Over this layer is fastened by glue thin China matting of
more or less ornamental nature, or in place of this matting, a matting woven of
so called Indian bast.
The whole is suitably pressed to secure the parts well together, and to give
greater security from the sail cloth side which is intended to be the outside, a
number of wire staples or cramps are preferably driven through the whole, and
secured by turning over their ends on or in the matting on the other side. The
staples or cramps may be of white metal or may be nickeled with the object of
preserving them from rust. If desired these wire staples may be omitted.
In the annexed drawing
Fig. 1 is a section of the material in a line across the fibres of the wood.:
Fig. 2 is a section on the line of the fibres of the wood.
Fig. 3 is a surface view on the side on which the matting is fixed.
Fig. 4 is a similar view on the side in which the sail cloth is secured.
a represents the wood, f the half round cane thereon, 6 the sail cloth, c the
manilla or other fibre d the matting and e the staples.
The relative thicknesses and spacing of these materials will be apparent in the
drawings and the method of securing them together will be readily understood from
the foregoing description.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
The material consisting essentially of a central stratum of wood, a layer of
fibres on the one side and slats of cane upon the other side thereof together with
surfacings of matting and of sail cloth, the whole secured with glue and pressed,
and with or without addition of wire staples as described and illustrated.
