PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Spinning-tops.
ERNST HEINRICH, Merchant 3 Mostyn Road Merton Park, Surrey, and
HEINRICH HOUFER, Merchant 10 Savage Gardens London E.C. do hereby
declare the nature of this invention to be as follows:-
This invention relates to the manufacture of discs for the class of spinning tops
which are provided with driving surfaces, i.e. surfaces which are roughened in such
a manner as to form indentations or projecting portions, into or against which a
current of air directed on to the top from the mouth by means of a tube or blow-
pipe or by other suitable means may act so as to effect the continued rotation of
the top.
The production of such driving surfaces has hitherto presented great difficulties
and was possible only at a prohibitive cost so that for this reason such tops have
as a matter of fact never yet found a way into the market.
The object of this invention therefore is, to provide a cheaper method of
producing these driving surfaces so that spinning-tops of this class can be sold at
a marketable price. A further advantage of our method is, that at one and the
same operation and without increasing the cost, the appearance of the discs may
be enhanced by suitable ornamentation. These ends we gain in producing the
roughened and ornamented driving-surfaces by means of an impression from dies,
on which the desired designs are engraved.
The material to be employed in the production of such discs is of secondary
consideration, as any substance of a suitable nature to receive the impression may
be used and we do not therefore restrict ourselves to any particular material, the
object of our invention being gained so long as the current resisting surfaces are
produced by an impression, which method has not hitherto been employed in the
production of the said driving-surfaces.

Improvements in the Manufacture of Spinning-tops.
ERNST HEINRICH, Merchant 36 Mark Lane, London E.C. and HEINRICH
HOUFER, Merchant 10 Savage Gardens, London E.C. 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 the manufacture of the class of spinning tops which
are provided with driving surfaces i.e. surfaces which are roughened in such a
manner as to form indentations or projecting portions into or against which a
current of air, directed on to the top from the mouth by means of a tube or blow-
pipe or by other suitable means, may act so as to effect the continued rotation of
the top.
The production of such driving surfaces has hitherto presented great difficulties
and was possible only at a prohibitive cost, so that for this reason such tops have
as a matter of fact never yet found a way into the market.

page_text: The object of this invention therefore is, to provide a method of manufacture by
which such tops with driving surfaces may be produced, to combine elegance of
design with a marketable price which up to now has been a matter of impossibility.
These ends we gain in producing the roughened and ornamented driving surfaces
either by impressions from dies (on which are engraved the desired designs) into
any plastic substance which may prove suitable for the production of such tops, or
by casts in moulds in which these driving surfaces are engraved. The substance
itself being of secondary consideration, we do not restrict ourselves to any
particular material, the object of our invention so far as the production of the
driving surfaces is concerned, being gained so long as these current resisting
driving surfaces are produced by impression or by casting, neither method having
hitherto been employed to produce the said current resisting or driving surfaces.
Tops of the above description mainly consist of a horizontal disc through the
longitudinal axis of which passes a pin or peg upon which the top rotates.
Both, discs and pegs, we produce in moulds by the compression of a suitable
plastic substance or by casting in moulds, sometimes disc and peg as two separate
pieces and sometimes as a complete top, disc and peg in one solid piece.
Where in this Specification the term "plastic substance" is used we mean to
designate any substance which is capable of receiving an impression from dies by
ordinary means which besides any suitable plastic composition may therefore also
include wood, soft metals, paper mâché, cardboard and the like.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :
First. The production, by means of an impression from dies, of current resisting
or driving surfaces op spinning tops.
Second. The production, by means of castings in moulds, of current resisting
or driving surfaces on spinning tops.
Third. Discs for spinning tops produced by the compression of any suitable
plastic substance with driving surfaces impressed thereon.
Fourth. Discs for spinning tops with driving surfaces produced by casting
in moulds.
Fifth. Pegs for spinning tops produced by the compression of any suitable
plastic substance.
Sixth. An entire spinning top provided with impressed driving surfaces which,
disc and peg complete, is produced in one solid piece by the compression of any
plastic substance.
Seventh. An entire spinning top provided with driving surfaces which, disc
and peg complete, is produced in one solid piece by casting in a mould.
