PROVISIONAL SPECIFICATION.
Improved Boards or Tables for Building Barracks and the like.
I, RUDOLPH MICHEL, of 1 Schenkendorf-Strasse, Leipsic in the Empire of
Germany, Consulting Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to improved composite boards or tables arranged for
making therefrom a complete barrack or a similar light building, the said boards
or tables being made of a heat non-conducting substance.
Such composite boards or tables are far superior to common boards or tables
that consist in timber frames and covers of paste-board, since the latter do not
afford any protection against heat or cold.
A composite board or table consists essentially in a frame of timber filled up by
a mass of the non-conducting substance and covered on both sides with a waterproof
lining.
The heat non-conducting substance may be made in any of the following manners:
Coarsely powdered cork waste is mixed with powdered asphalt, then the mixture
strongly heated in some vessel by steam and afterwards pressed in forms. Or
coarsely powdered cork wood or vegetable pith may be employed instead of the
cork waste. The asphalt may be replaced by cement or lime or by a mixture of
the following substances or some of them in suitable proportions: Cement, sand,
clay, lime, hair or vegetable fibres. Where it is so preferred, the heating of the
mass by steam may be dispensed with, in which case the mass is simply dried by
exposing it to the action of the air.
The timber frame enclosing the pressed and dried non-conducting substance is
provided on the inner edge surfaces with tongues for securely holding the said
substance. The frames are so arranged that they can be put up to form the
barrack or other building and leave openings for windows, doors and the like. For
walls or roofings the frames are provided with recesses and projections at the edges
and made to overlap each other or to fit in recesses of posts or rafters. The joints
are then secured either by galvanized nails or by bolts passing through the

there be any, laths are first nailed to the vertical faces of the beams to form
recesses and then the frames laid in the recesses to make their upper faces level with
those of the beams.
The waterproof covers may be linen cloths impregnated with suitable stuffs
They may be first fastened on both sides of the boards or tables by galvanized
nails or similar means, before the boards or tables are put up in building the barracks
and the like. Or the boards or tables may be first put up, ere the waterproof
covers are placed and fastened on them. This is especially done for the outside

waterproof cover is placed both on the boards or tables and on the posts, rafters
or beams, so as to afford even surfaces. Where necessary, the pieces of the
waterproof covering are made to overlap each other.

I, RUDOLPH MICHEL of 1 Schenkendorf-Strasse, Leipsic in the Empire of
Germany, Consulting Engineer 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 :-
This invention for improved boards or tables for building barracks and the like
has for its object to provide composite boards, tables, or slabs of heat non-conducting
material for use in the construction of barracks or other light buildings, and
consists in forming such slabs of a frame of timber, filled up by non-conducting
material and covered on both sides with a waterproof covering.
In slabs constructed according to this invention, plates of ground cork or other
non-conductors of heat are inserted in wooden frames and connected together by
wood or iron binders, plaster of Paris, cement and coated on each side with an
impervious material, such as waterproofed linen, or sheet metal.
The non-conducting plates are made from coarsely powdered cork waste, mixed
with powdered asphalt, heated by steam and afterwards pressed in forms. Or
coarsely powdered cork, wood, or vegetable pith may be employed instead of the
cork waste and the asphalt may be replaced by cement or lime or by a mixture of
cement, sand, clay, lime, hair, or vegetable fibres in suitable proportions. Instead
of heating the mixture by steam it may be allowed to dry in the air.
The timber frame enclosing the non-conducting substance is provided with
tongues on its inner edge surfaces which form grooves in the pressed material and
hold the same in position.
The slabs are adapted for use in constructing either the roofing, walls, or floors
of buildings. For walls or roofing the frames are formed with recesses and
projections at the edges and made to overlap each other or to fit in recesses of
posts or rafters, the joints being secured either by galvanized rails or by bolts
passing through the overlaps or through angle irons at the rafters. For floors and
ceilings, luths are nailed to the vertical faces of the joists to form recesses in which
the frames are laid with their upper faces level with those of the joists.
The waterproof covers are fastened on both sides of the frames by galvanized
nails or other suitable means.
With reference to the accompanying drawings
Fig. 1 is an elevation of a slab constructed according to this invention with the
waterproof coating removed.
Figs. 2, 3 and 4 are vertical transverse sections of slabs having different forms
of binders.
The frame A, enclosing the plates of non-conducting material B, is provided at
intervals with tongued or binding pieces C, the whole being covered by the
waterproof coating D.
The binders may be of different shapes in section as shown in Figs. 2 and 3. In
Fig. 4 the binders are replaced by metallic cement strips E.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The production of slabs from plates of ground cork or other bad' conducting
material inserted in wooden frames and connected together by plaster, cement, or
the like, and both sides of which are coated with waterproofed inaterial, or metal
whereby they are rendered completely capable of resisting all conditions of weather
or temperature.

page_text: 2. The combination of several abutting ground cork plates B, in frames A, by
inserted tongues or ribs C, or metallic cement E.
3. The use of slabs constructed according to Claims (1) and (2), capable of
resisting all outside influences, for the erection of temporary barracks and all kinds
of light buildings and erections.
4. The improved boards or tables for building barracks and the like substantially
as described with reference to the drawings.
