PROVISIONAL SPECIFICATION.
Improved Manufacture of Wood Panelling and Sheathing for
Bodies of Vehicles, Perambulators, and Travelling Trunks.
I, CHRISTIAN WILHELM LUTHER, of Reval, Russia, Manufacturer of Wooden
Articles, do hereby declare the nature of this invention to be as follows:-
The object of this invention is an improved mannfacture of wood panelling, and
sheathing for bodies of vehicles, perambulators, and travelling trunks.
The sides, roofs, and other parts of tram. car and wagon bodies, have up to now,
as is well known, been made of boards, on which then a plate was affixed, either
directly upon the wood, or with an intervening layer.
The present invention has for object, the manufacture of same of several layers
which are joined to each other crosswise in several layers (5 to 7), and in a water-
tight manner.
The layers or veneers painted with special glue, such as that made from lime and
air dried caseine, are put together with the grain or fibres crosswise, and the whole
is brought between a press, which is shaped according to the form of the several
parts. After these veneer parts have been under pressure for a certain time in this
press say, 6 hours, they are taken out, dried, cleaned, and are then ready for use.
These veneers are fixed or secured by means of screws, or rivets upon angle irons,
or wood ribs, the exposed ends must be covered in with zinc, or be protected by the
insertion of grips.
The car when complete has to be protected again by repeated painting and
lacquering, or varnishing.
The advantage offered by the use of these veneers consists in the reduced weight,
increased strength, elegance of form and reduced price.
Travelling trunks, or parts for perambulators may be made in the same manner.

COMPLETE SPECIFICATION.
Improved Manufacture of Wood Panelling and Sheathing for
Bodies of Vehicles, Perambulators, and Travelling Trunks.
I, CHRISTIAN WILHELM LUTHER, of Reval, Russia, Manufacturer of Wooden
Articles, 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 improved manufacture of wood panelling and
sheathing for bodies of vehicles, perambulators, and travelling trunks.
Panels, side roofs, and other parts of omnibuses, cabs, tram car and vehicle
bodies generally have up to now, as is well known, been made of boards, on which
a plate is sometimes affixed, either directly upon the wood, or as an intervening
layer.
The present invention has for object, the manufacture of such parts from several
layers of veneers which are joined to each other in the flat and with the fibres
arranged crosswise in several layers (5 to 7) by a waterproof glue.
To carry the invention into practice, I paint layers, or veneers of the same, or of
different woods with special glue, such as that made from lime and air dried caseine,

page_text: these are put together with the grain or fibres of the layers crosswise, and the
whole in a combined condition put under pressure, which shapes it according to
the form required. After these associated veneers have been under pressure for a
time for perfect attachment, say, 6 hours, they are taken out and dried, then rubbed
down ready for use. These veneers thus prepared can be fixed, or secured by
means of screws, or rivets upon angle irons, or wood ribs, and where the edges or
ends are exposed, they could be covered with zinc clips, or be protected in any
suitable manner.
The waterpoof panelling or other sheet or piece veneer thus prepared can be
painted, stained, or varnished according to fancy.
The advantages offered by the use of these veneers, consist in durability, reduced
weight, increased strength, elegance of form, reduced price, and from their being
impervious to moisture.
Travelling trunks, boxes, cases of all kinds may be made from the same kind of
combined veneers and will prevent climatic action upon the contents.
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 :-
Uniting superposed veneers laid cross grained among themselves with a
waterproof glue or cement, and the employment of such united veneers as panels,
sides, roofs, and other desired parts of vehicles, and for articles, such as trunks,
boxes, cases, and the like, as set forth.
