An Improvement in or connected with the Manufacture of
Framework for Carriages, Boats, and Trunks.
We DAVID MARCUS of 40 Charterhouse Square E.C. Merchant and EDGAR
HORNER of 13 Charterhouse Buildings Aldersgate Street, E.C. Agent do hereby
declare the nature of this invention to be as follows:-
Our invention relates to the manufacture of framework and outside covering for
carriages boats and trunks and other similar purposes by the combination of canc
or wood and Japanese lacquer.
In using the cane we take strips and placing them side by side cement them on
one or more pieces of canvas or other suitable material and with the use of
machinery compress the whole into a solid sheet.
The cane or wood actually employed is not heavier or thicker than cane or wood
usually used for such purposes but we strengthen the sheet by placing the strips of
cane or wood in two thicknesses horizontally and transversely. To the groundwork
of cane or wood and canvas so prepared we add Japanese lacquer in the following
manner :-
A mixture must be made containing about 40% of raw lacquer the sap or juice
of the Khus vernicifera 30% of Jinoko, a species of burnt earth from Japan
and 30% of Tonoko or iron ochre powder from Japan.
This mixture is to be spread over a sheet of cane or wood and canvas prepared
When the sheet has
as aforesaid and the sheet placed to dry in a damp room.
thoroughly dried the surface of the sheet must be rubbed down smooth with
charcoal or other rubbing material and another coat of the same mixture should be
placed upon the first coat and the drying and rubbing down repeated.
Over the smooth surface so prepared a coat of raw lacquer only is to be placed
and dried. Upon that a coat of dull black lacquer should be applied and this also
must be thoroughly dried and then rubbed down.
Upon the surface so prepared two layers of Roiro lacquer or lacquer mixed with
vermillion ochre or other colors according to the color desired to be obtained should
be thinly and smoothly applied each of them being thoroughly dried and then
rubbed down.
The smooth surface resulting from this process can be polished with raw lacquer
and deer's horn until it is perfectly smooth and bright.
Great care must be taken that no dust falls upon the lacquer and that the
rubbing down is not attempted until the coatings are perfectly dry but the drying
may when necessary be hastened by placing damp canvas round the prepared sheets.
The rubbing down should not be more than is necessary to give a smooth surface
to a coat in order that advantage may result from successive coats thinly laid one
above the other. The layers of lac so affixed serve both to form a smooth and
watertight covering and also by the penetrating power of Japanese lac to soak into
and adhere to the cemented and compressed cane or wood and canvas in such
manner as to form with it a sheet of material ready for use for carriages boats and
trunks and suitable for being cut without injury into any desired shape like a piece
of wood or metal.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The method of forming a framework or sheet of material ready for use in the

set forth by the combination of cemented and compressed cane or wood and canvas
prepared as aforesaid and successive layers of Japanese lacquer prepared substan-
tially as herein described.
