Paint or Composition to be used as a Coating, more especially in the
Manufacture of Artificial Slates, and for Coating Tiles, Plates, and
other articles.
CLAES ALGOT HÅKANSON, of Kalmar, Sweden, Dealer, JOHAN HENRICK HÁKANSON,
of Svaneberg, Kalmar, Sweden, Farmer, ARON RUDOLF HÅKANSON, of Karlshaum,
Sweden, Dealer, do hereby declare the nature of this invention to be us follows:-
This invention relates to a kind of paint or composition to be used as a coating
more especially in the manufacture of artificial slates, but also applicable to the
couting of any surface to which it is desired to give a coating that will protect it
against the influence of moisture or of the atmosphere & give it an ornamental
appearance. Another mode of using the paint in question is for coating plates,
tilos or pieces either of a stiff material such as pasteboard or of a pliable material,
such as cloth skin or the like, which plates tiles or pieces may be used for the
inlaying or covering of surfaces, as for instance surfaces of furniture, in making
immitation marble table-tops, parquet floors & the like, or for the production of
various other articles such as building materials etc. The paint consists of a fine-
grained mass of very finely divided sandstone, sand or other suitable fine-grained
substance. The mass obtains the desired colour by the addition of a colouring
matter. If the paint is to be black, Brazil-wood & chromic acid, for instance,
may be added. To the coloured, fine-grained mass there are added 73 grammes of
boiled linseed-oil, 108 grammes of a warm solution of common boiled glue, 18
grammes of cerotine or other suitable drier, and 18 grammes of turpentine. These
constituents are mixed well together with one kilogramme of the coloured, fine-
grained mass which should be half dry, a kind of jelly being thus formed. If a
largo quantity of this jelly is prepared at once, it is well to keep it, during the work,
in air-tight chambers, so as to prevent it from hardening. A priming cont of
this jelly is, in the first place, spread with common flexible spatulas made of spring
steel, over the pieces of paste-board, etc., which are to form the slates or are to be
used for inlaying or covering surfaces etc. as mentioned above. When the com-
position has dried on the pieces of paste-board, the latter are coated a second time
with the same composition & are afterwards placed closely together on a long level
table provided with small rails over which a carriage, 50 to 75 centimetres in length
runs on rollers, the said carriage being fitted with a number of adjacent, adjustable
& very elastic spatulas, made of thin spring-steel, which spatulas are made to exert
a considerable pressure against the composition forming the coating, while the
carriage is repeatedly moved over it at brief intervals until a glossy surface resem-
bling patent leather is finally produced. The pieces are then left to dry, after
which the glossy coating, which is insoluble in water, prosents a surface of soft
appearance & agreeable to the touch. If the plate thus produced is to be used as
a slate, it should, of course, be made black, unless it is the intention to use artificial
coloured slate-pencils; on the other hand, if the plates are to be employed for inlaid

page_text: work or as a covering material, their colour may be varied by the addition of suit-
able colouring substances, in order to admit the grouping of the plates or pieces
thereof in patterns or configurations, in the manner already known, for instance
in the making of parquet floors. Moreover different shades of colour may be given
to the plates whilst the coats of composition are being applied, the plates thus
treated acquiring a marbled appearance.

CLAES ALGOT HÅKANSON, of Kalmar, Sweden, Dealer, JOHAN HENRIK HÅKANSON,
of Svanoberg, Kalmar, Sweden, Farmer, ARON RUDOLF HAKANSON, of Karlshuum,
Sweden, Dealer, 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 relates to a kind of paint or composition to be used as a coating,
more especially in the manufacture of artificial slates, but also applicable to the
coating of any surface to which it is desired to give a covering that will protect it
against the influence of moisture or of the atmosphere & give it an ornamental
appearance. It may be applied for coating plates, tiles, or pieces either of a stiff
material such as pasteboard, or of a pliable material such as cloth, skin or the like,
which plates, tiles or pieces may be used for the inlaying or covering of surfaces
as for instance surfaces of furniture, in making imitation marble top tables, parquet
floors & the like, or for the production of various other articles, for instance,
building materials, etc.-The paint consists of a fino grained mass of very finely
divided sandstone, sand or other suitable fine-grained substance. The mass obtains
the desired colour by the addition of a colouring matter. If the paint is to be
black, Brazil-wood & chromic acid for instance, may be added. To the coloured,
fine grained mass there are added 73 grammes of boiled linseed-oil, 108 grammes of
a warm solution of common boiled glue, 18 grammes of cerotine or other suitable
drier, & 18 grammes of turpentine. These constituents are mixed well together
with one kilogramme of the coloured, fine grained mass which should be half dry,
a kind of jelly being thus formed. If a large quantity of this jelly, is prepared a
at once, it is well to keep it, during the work in air tight containers, so as to
prevent it from hardening. A priming coat of this jelly is, in the first place,
spread with common flexible spatulas, made of spring steel, over the pieces of paste
board, etc. which are to form the slates or are to be used for inlaying or covering
surfaces etc. as mentioned above. When the composition has dried on the pieces
of pasteboard, the latter are coated a second time with the same composition & are
afterwards placed closely together on a long level table provided with small rails
over which a carriage, 50 to 75 centimetres in length runs on rollers, said carriage
being fitted with a number of adjacent, adjustable & very elastic spatulas, made of
thin spring steel, which spatulas are made to exert a considerable pressure against
the composition forming the coating, while the carriage is advanced repeatedly over
it with brief intervals until a glossy surface resembling patent leather is finally
produced. The pieces are then left to dry, after which the glossy coating, which is
insoluble in water, presents a surface of soft appearance & agreeable to the touch.

page_text: If the plate thus produced is to be used as a slute, it should of course, be made
black, unless it is the intention to use artificially coloured slate-pencils; on the
othor hand, if the plates are to be employed for inlaid work or as a covering
material, their colour may be varied by the addition of suitable colouring sub-
stances, in order to admit the grouping of the plates & pieces thereof in patterns
or configurations, in the manner already known, for instance in the making of
parquet floors. Moreover different shades of colour may be given to the respective
plates, for instance when the coats of the composition are being applied, the plates
thus acquiring a marbled appearance. In order to give the composition a paint
like consistency linseed oil is added.
Having now particularly described & ascertained the nature of our said invention
& in what manner the same is to be performed, we declare that what we claim is :—
1). Paint or composition to be used as a conting more especially in the manu-
facture of artificial slates or for plates tiles etc. to be used for inlaid work or as a
covering material etc. consisting of a fine powder of sandstone, sand or a similar
fine grained material, linseed oil, boiled glue, turpentine & a suitable drier for
instance cerotine, with or without the addition of special colouring matters, sub-
stantially as described.
2) Artificial slates, consisting of a piece of stiff pasteboard, or other suitable
material, coated with the paint or composition specified in Claim I, & subsequently
glazed, substantially as described.
3) Plates, tiles or pieces for the inlaying or covering of surfaces or for the
production of various other articles, which plates etc. consist either of a stiff
material such as pasteboard, or of a pliable material, such as leather, cloth or the
like, said plates etc. being coated with the paint or composition specified in Claim 1,
substantially as described.
