Improvements in and relating to the Manufacture of Dolls.
I, HERRMANN SCHIMANSKY, of 10 Brücken-Strasse, Berlin, S.O., in the Kingdom of
Prussia, German Empire, Manufacturer, do hereby declare the nature of this invention
to be as follows :-
This invention relates to the manufacture of dolls. In lieu of making doll heads
and limbs of porcelain or undurable paper pulp, I produce these parts of cast metal.
I will proceed to describe by way of example the manufacture of a doll head in
accordance with the said invention. The head is made of a main part and a cap
which are connected by means of a rebated joint.
The main part of the head consists of what 1 term turn-moulded cast metal, that is
to say -Into a suitable metal-mould the liquid metal is cast, and then solidifies on
the walls of the colder mould to form a crust. The thickness of this crust depends
chiefly upon the temperature of the mould and the metal introduced into the same,
When in accordance with
and on the time which the metal is left in the mould.
experience the solidified crust is thought to have attained the proper thickness, the
mould is turned in order to pour out the remainder of the metal that is still liquid.
In the present example the mould for the main part of the doll head is preferably
such that the opening which is formed at the top of the head and subsequently
covered by the cap is closed and the metal is cast into the opening of the neck, the
mould being held in such a position that the said opening of the neck is upwards
during the casting. At the place where the opening for the cap is to be formed no
metal will adhere to the mould if the corresponding part of the latter is coated with
plaster or similar material.
The metal preferably used for these turn-moulded castings is zinc, tin or an alloy of
tin and lead, according, as more or less resistive heads are to be obtained. After the
necessary dressing or cleaning of the seams or burrs and the like, the doll head'
receives a coating of non-poisonous lacquer or varnish which in order to cause it to
adhere well can be applied hot or prevented in any other suitable manner from
subsequent scaling. The said coating can then be powdered, painted or coloured in
any desired manner.

page_text: The aforesaid main part of the doll head is cast with a projecting edge or rebate for
securing the cap thereon. The latter is suitably produced of what is termed
< 'immersion cast metal" in the same manner as the well-known tin brilliants are
made. For this purpose a polished metal-mould representing in this case a segment
of a hollow sphere is immersed or plunged into liquid tin or an alloy of tin and lead.
A thin layer of the metal adheres to the polished part or parts of the mould, and on
having solidified can be readily removed from the same. Upon the spherical cap thus
obtained may be pasted a wig, after which the cap can be secured to the rebate of the
head by solder or putty. When the moulds are properly made the joint can scarcely
be seen even if solder or putty, is not used and it is moreover covered by the hair of
the wig. It is advisable not to apply solder or putty to the entire joint but only to
some points of the same, say to three or four points so that if repairs may subsequently
be necessary the cap can be easily separated to allow, access to the interior of
the head.
For doll heads the chief advantage of the described mode of manufacture is that
porcelain eyes or the mechanism for movable eyes and the like can be inserted and
removed with facility, because this work can be conveniently done when the cap has
been taken off.
In like manner, the limbs of dolls can be made and composed of so-called "turn-
moulded" and "immersion" castings. If comparatively soft alloys are employed,
these castings can subsequently be bent so that for instance the hands are flexible to a
certain degree and are adapted for holding articles put in them.

Improvements in and relating to the Manufacture of Dolls..
I, HERRMANN SCHIMANSKY of 10 Brücken-Strasse, Berlin, S.O., in the Kingdom
of Prussia, German Empire, Manufacturer, 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 dolls. In lieu of making dolls' heads
and limbs of porcelain, paper pulp, or other fragile or undurable substance, I produce
these parts of cast metal.
In the accompanying drawing,
Figure 1 is a transverse section, and
Figure 2 a back elevation of a dolls head constructed according to the present
invention.
The head is made of a main part A and a cap B which are connected by means of a
rebated joint.
The main part of the head A. consists of what I term turn-moulded cast metal, that
is to say into a suitable metal-mould the liquid metal is cast, and then solidifies on
the walls of the colder mould to form a crust. The thickness of this crust depends.
chiefly upon the temperature of the mould and the metal introduced into the same,
and on the time which the metal is left in the mould. When in accordance with
experience the solidified crust is thought to have attained the proper thickness,
the mould is turned in order to pour out the remainder of the metal that is
still liquid.
In the present example the mould for the main part A of the doll head is preferably
such that the opening which is formed at the top of the head and subsequently covered
by the cap B is closed and the metal is cast into the opening of the neck, the mould
being held in such a position that the said opening of the neck is upwards during the
casting. At the place where the opening for the cap is to be formed no metal will
adhere to the mould if the corresponding part of the latter is coated with plaster or
similar material. The piece or part obtained after the casting is illustrated in back
elevation in Figure 2.
The metal preferably used for these turn-moulded castings is zinc, tin or an alloy
of tin and lead, according as more or less resistive or durable heads are to be obtained.
After the necessary dressing or cleaning of the seams or burrs and the like, the dolls
head receives a coating of non-poisonous lacquer or varnish which in order to cause
it to adhere well can be applied hot or prevented in any other suitable manner from
subsequent scaling. The said coating can then be powdered, painted or coloured in
any desired manner.
The aforesaid main part A of the dolls head is cast with a projecting edge or
rebate a (Figure 1) for securing the cap B thereon. The latter is suitably produced
by what is termed "immersion cast metal" in the same manner as the well-known
tin brilliants are made. For this purpose a polished metal-mould representing in this

page_text: case a segment of a hollow sphere is immersed or plunged into liquid tin or an alloy
of tin and lead. A thin layer of the metal adheres to the polished part or parts of
the mould, and on having solidified can be readily removed from the same. Upon the
spherical cap thus obtained may be pasted a wig, after which the cap can be secured
to the rebate a of the head by solder or putty. When the moulds are properly made
the joint can scarcely be seen even if solder or putty is not used, and it is moreover
covered by the hair of the wig. It is advisable not to apply solder or putty to the
entire joint but only to some points of the same, say, to three or four points so that
if repairs may subsequently be necessary the cap can be easily separated to allow access
to the interior of the head.
For dolls heads one great advantage of the described mode of manufacture is that
porcelain eyes or the mechanism for movable eyes and the like can be inserted and
removed with facility, because this work can be conveniently done when the cap has
been taken off.
In like manner, the limbs of dolls can be made and composed of so-called "turn-
moulded" and "immersion" castings. If comparatively soft alloys are employed,
these castings can subsequently be bent so that for instance the hands are flexible to
a certain degree and are adapted for holding articles put in them.
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 ;
First. The manufacture of dolls heads and dolls' limbs of "turn moulded castings"
and "immersion castings," as described..
Second. The connection of the two parts of the dolls' head by means of a joint
which can be made by soldering or luting, as described and represented in the
drawing.
