Year: 1887

page_text: This Specification was, upon the 1st day of May 1888, amended (under Sections 18
to 21 of the Patents, Designs, and Trade Marks Act, 1883) by the addition of
the name of Arnold Trebitsch as joint inventor..
I, We JAMES KARPELES, of VI. Gumendorfer Strasse 41 Vienna, Austria, Ainber-
ware manufacturer, and ARNOLD TREBITSCH of V. Hundsthurmstrasse 7, Vienna
Austria Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to concrete amber shavings and amber-powder into
pieces of sufficiently large volume as to be fit for being turned or carved.
According to this invention, the amber particles to bo concreted are heated in a
strong cylindrical vessel, to a temperature of about 400° Fabr., when the said particles
will become plastic and viscous, without however undergoing any decomposition, as
would be the case at temperatures near 500° Fahr.
As soon as the amber particles are in the desired condition, a cover of considerable
thickness is placed in the aforesaid cylindrical vessel the said cover fitting such vessel
like a piston and being provided, on its upper surface, with a projecting portion of
preferably rectangular form. This projecting portion of the cover or piston is
provided with a number of fine perforations, extending to the underside of the cover;
it fits the under end of the inner hollow space of a mould, destined to be placed on
the cover or piston and fitting by its cylindrical outer surface the cylindrical vessel,
which contains the heated aimber particles. For this mould, guiding pillars are
provided on the cylindrical vessel, and when the mould is in place, above the projecting
part of the cover or piston and between the guiding pillars, a heavy block of metal

page_text: such as copper, loosely fitting the hollow space of the mould, is placed within said
space; a second strong flat cover is then laid on the top of the mould, this cover
having holes through which the top ends of the guide pillars project.
Thus prepared, the whole is placed under a powerful press by preference under a
hydraulic press by operating which, the mould is caused to descend into the
cylindrical vessel, carrying with it the perforated cover or piston. The plastic amber
mass will then be forced through the perforations of the cover or piston and on
entering the mould it will lift the copper block and fill the mould until the said block
has reached the second cover. The pressure may then be allowed to act on the plastic
mass, until it is perfectly cooled and hardened.

4, We JAMES KARPELES, of Vienna, Austria, Amber-ware Manufacturer, and
ARNOLD TREBITSCH of V. Hundsthurmstrasse 7, Vienna Austria, 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 has for its object to concrete amber shavings and amber powder into
pieces of sufficiently large volume to be fit for being turned or carved.
According to this invention, the amber particles to be concreted are heated in a
strong cylindrical vessel, to a temperature of about 300° Celsius, when the said
particles will become plastic and viscous, without, however, undergoing any
decomposition.
When the amber particles are in place, a cover of considerable thickness is placed
in the aforesaid cylindrical vessel, the said cover fitting such vessel like a piston, and
being provided, on its upper surface, with a projecting portion provided with a number
of fine perforations, extending to the underside of the cover.
The said projecting
portion fits the under end of the inner hollow space of a mould, destined to be placed
on the cover, and fitting by its cylindrical outer surface the cylindrical vessel, which
contains the amber particles. For this mould, guiding pillars are provided ; and,
when the mould is in place, above the projecting part of the cover and between the
guiding pillars, a heavy block of metal, such as copper, loosely fitting the hollow space
of the mould, is placed within said space; a second strong flat cover is then laid on
the top of the mould, this cover having holes through which the top ends of the guide
pillars project.
Thus prepared, the whole is heated and placed under a powerful press-by preference
a hydraulic press-by operating which, the mould is caused to descend into the
cylindrical vessel, carrying with it the perforated cover. The plastic amber mass will
then be forced through the perforations of the cover, and on entering the mould it
will lift the copper block and fill the mould until the said block has reached the
second cover. The pressure may then be allowed to act on the plastic mass, until it
is perfectly cooled and hardened.
Referring to the accompanying sheet of drawings-
Figure 1 is a vertical section, and
Figure 2 a sectional plan on the line A B, Figure 1, of means or apparatus according
to this invention for concreting amber particles.
1. is a cylindrical vessel within which are placed the amber shavings or particles 2
to be concreted; it is closed at its lower end by a removable base piece 3 of truncated
conical form at its lower side. Within the cylindrical vessel 1 is a cover fitting after
the manner of a piston and comprising a part 4 (constructed as I prefer of steel) and
a part 5 (as I prefer of copper). The upper portion of the part 4 and the inner edge
of the part 5 are made approximately of rectangular forin in cross section and so as

page_text: to project a short distance above the upper surface of the part 5. 6, 6, are groups of
fine holes (or fine slit may be used) which pass partly through the part 4. The holes of
cach group communicate at their lower ends with a hole 7 of larger diameter which
extends to the underside of the cover. 8 is a mould, the hole 9 formed therethrough
corresponding in size and shape with the external conformation of the raised part of
the cover which enters the said hole as shown when the parts occupy the relativo
positions shown in Figure 1. The lower part 10 of the mould 8 is of a size adapted
to enter the cylindrical vessel 1 during the operation of concreting the amber particles.
11 is a block of metal, such as copper, which loosely fits the hole 9 in the mould S.
12 is a cap or cover formed with a recess 13 in its lower sido adapted to receive and
hold in position the upper end of the mould 8 but so nevertheless as to admit of the
escape of air from the space above the block 11 when this is raised by the entry of the
concreted amber particles beneath it. 14, 14, are guido pillars secured to the cylindrical
vessel 1 and passing freely through holes in the cap or cover 12; they are provided
with nuts 15 whereby the several parts of the apparatus may be firmly secured
together preparatory to being subjected to pressure.
In carrying out my improved process the amber particles are placed in the vessel 1
and may be then heated to a suitable temperature as hereinbefore stated so that they
form a plastic mass before the several parts of the apparatus are secured together.
1 prefer however to secure the said parts together in the manner shown in figure 1
of the drawings, before applying heat. The apparatus is then placed in a suitable
hydraulic or other press and is afterwards heated. The apparatus is then subjected
to pressure applied to its upper and lower ends, the lower end of the mould & being
thereby caused to enter the vessel 1 and cause the plastic mass of amber to flow in
fine streams through the holes in the cover 4-5 and thence into the mould 8 where
they are caused by the block 11 to re-unite as a mass which becomes solid on cooling.
By the described treatment of the amber in a plastic state a product of practically
uniform quality can be obtained. When the amber has been forced from the lower
part of the vessel through the holes 6, 7, in the piston like cover 4-5 the apparatus is
allowed to cool, it may be whilst under pressure, and the block of concreted amber
then removed. The heating of the apparatus may be effected in any suitable manner,
as for instance by a ring of gas jets arranged to impinge upon the exterior of the
vessel 1.
It will be obvious that my improved process of concreting amber particles may be
carried out in apparatus differing more or less in construction from that herein before
described and shown in the drawings, and that the number of holes through which
the plastic amber is caused to pass may be varied within wide limits.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1. The described process of concreting amber shavings or particles.
2. In the process of concreting amber shavings or particles, forcing the amber
whilst in a plastic state through holes or passages into a mould or chamber in which
concretion is effected.
3. My concreting apparatus as described and shewn for the purpose specified.
4. For concreting amber shavings or particles apparatus provided with a perforated
cover or division substantially as described.
