Complete Specification Left, 16th Aug., 1900-Accepted, 3rd Nov., 1900
This invention relates to a stereotype casting apparatus which enables per-
fectly cylindrical or segmental stereotype plates or formes to be produced so that
the very expensive engraved cylindrical surfaces such as are used for designs of
wall papers and the like are dispensed with, and whereby in particular the pro-
duction of numerous cast formes having the same designs is effected almost free
of cost.
Referring to the accompanying drawings, the apparatus consist mainly of;
1. The casting apparatus A.
2. The hollow body B forming the core of A.
The apparatus A consists of two or more parts A1 and A2, as shewn in end view
and side elevation at Figs. 1 and 2, connected by a hinge a, such parts having a
semi-cylindrical hollow, and serving to receive and hold the core B by means of
the rings F.
The part A, for the sake of easy manipulation and accurate fitting in of the
core B, is divided into two parts, about in the proportion of 1: 2, and these parts
are also connected by a hinge a¹.
Between the parts A¹ and A2 are arranged detachable pieces A³, in order also
from this point to be able to observe and regulate the accurate fit of the parts,
and also, in order after the removal thereof, to be able to apply the casting git C
Figs.
and 2, provided on one side with a hinge. Against the two ends of the
piece A³ abut end pieces A+ which can be slid in and out endwise. On closing up
the apparatus, the parts A1 and A2 thereof are secured in position by means of
the stirrup pieces D) with screws 6', and pivoted to screws b, Figs. 1 and 2.
The hollow core B, shewn separately in longitudinal and transverse sections at
Figs. 3 and 4, consists of several wedge shaped pieces, such as six, as shewn on
the drawing, which are held together by means of rings or end caps B¹, and which
fall apart on the removal of the latter. For more convenient manipulation, such
as for the introduction and removal of the core into and from the apparatus, as
also for readily placing and removing the said caps, these are formed with threaded
holes into which handles can be screwed. The rings E Figs. 1, 2, shewn
separately in elevation and section at Fig. 5, which are internally coned on one
side and are also there reduced somewhat in outer diameter for securely holding
the matrix M, from which the forme is to be cast, constitute the actual connecting
pieces between the apparatus and the core. These rings can be shifted according
to the width of the forme to be cast, and for easy manipulation they are cut
through.
By means of the longitudinal insertion pieces G Figs. 1, 2, shewn separately
in side and end views at Fig. 6, which are formed with their ends bevelled to
correspond with the internal coned surface of the rings F so as to engage with
these, any cast formes can be produced that do not constitute complete cylinders,

page_text: as shewn at Fig. 1, the extent of the forme being determined by the position of
the pieces G. The casting of the formes can be effected either from the side sur-
face or in the case of complete cylinders from the end surface of the apparatus.
In the first named case the apparatus is placed horizontal and a casting git as
shewn at C Figs. 1 and 2 is used, the sides C' of which one can be folded down
on a hinge, and which are connected by the end walls C2 that are hooked in as
shewn the git is fixed by screws in place of the piece A³. In the second named
case the apparatus is placed upright on a stand H as shewn in the modification
Figs. 7 and 9, and the casting grit K1 K2 is fixed on the upper end surface of A
and B; the outer funnel shaped part K¹ of the git being formed in two parts for
facility of removal, and secured to the apparatus A, while the inner cylindrical
part K2 is fixed on the core B.
The connecting ring F situated nearest the git K can in this case be formed
with openings through it, as shewn by the modification at Fig. 8, or it may be
replaced by a suitable device which both holds the matrix and also allows the
casting to be effected.
When the apparatus is to be used, it is opened, the matrix M is introduced,
the core B is fitted on the introduced half rings F. by means of the handles 73,
and upon it are fitted the other half rings, on which the remaining portions of the
matrix are then placed. The part A³ is removed and the casting git C is applied,
and after closing up the apparatus it is secured by the stirrups D) and screws b¹.
The end walls C2 of the casting git having been hung on to the side walls C¹,
the casting can then be effected in the same manner as with any other apparatus.
If the matrix is perfectly closed, or if a complete cylindrical design is cast,
the matrix &c. is carefully introduced in the half open apparatus and this is then
closed without removing the piece A³, or if this was previously removed for regu-
lating the matrix, it is placed in position again, and is secured by means of the
clamps turning on pins f¹ and held by locking latches Fig. 7. The whole
being then secured in the closed position by means of the stirrups D and screws bl
as above described, the apparatus is placed upright on the base H and the casting
git KK having been fixed on the upper end, the casting of the forme is effected.
In both the above cases, the apparatus is opened after casting, the core B
together with the cast forme and matrix are lifted out of the apparatus, and after
removing the matrix in the usual manner, the rings or caps B are removed from
the core B; the latter then collapses and the pieces having been removed from
the interior of the cast forme, this is ready to be used for printing. The core B
is then fitted together again and secured by the caps B' for repeating the casting
operation.

Improvements in Stereotype Casting Apparatus.
I, ISIDOR LAM, of IX Glasergasse 22, Vienna, Austria, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to a stereotype casting apparatus which enables per-
fectly cylindrical or segmental stereotype plates or formes to be produced so that
the very expensive engraved cylindrical surfaces such as are used for designs of

page_text: wall papers and the like are dispensed with and whereby in particular the pro-
duction of numerous cast formes having the same designs is effected almost free
of cost.
Referring to the drawings accompanying the Provisional Specification the
apparatus consist mainly of:
1. The casting apparatus A.
2. The hollow body B forming the core of A.
The apparatus A consists of two or more parts A' and A2 as shewn in end view
and side elevation, Figs. 1 and 2, connected by a hinge a, such parts having a
semi-cylindrical hollow, and serving to receive and hold the core B by means of
the rings F.
The part A, for the sake of easy manipulation and accurate fitting in of the
core B, is divided into two parts, about in the proportion of 1: 2, and these parts
are also connected by a hinge a¹.
Between the parts A1 and A2 are arranged detachable pieces A³, in order also
from this point to be able to observe and regulate the accurate fit of the parts,
and also in order after the removal thereof, to be able to apply the casting git O
Figs. 1 and 2. provided on one side with a hinge. Against the two ends of the
piece A3 abut end pieces A+ which can be slid in and out endwise. On closing up
the apparatus the parts A1 and A2 thereof are secured in position by means of
the stirrup pieces D with screws and pivoted to screws b, Figs. 1 and 2.
The hollow core B shewn separately in longitudinal and transverse sections in
Figs. 3 and 4, consists of several wedge shaped pieces, such as six, as shewn on
the drawing, which are held together by means of rings or end caps B¹, and which
fall apart on the removal of the latter. For more convenient manipulation. such
as for the introduction and removal of the core into and out of the apparatus as
also for readily placing and removing the said caps, these are formed with threaded
holes into which handles 73 can be screwed. The rings F Figs. 1, 2, shewn
separately in elevations and section in Fig. 5, which are internally coned on one
side and are also there reduced somewhat in outer diameter for securely holding
the matrix M, from which the forme is to be cast, constitute the actual connecting
pieces between the apparatus and the core. These rings can be shifted according
to the width of the forme to be cast, and for easy manipulation they are cut
through.
By means of the longitudinal insertion pieces G Figs. 1. 2. and shewn separately
in side and end views at Fig. 6, which are formed with their ends bevelled to
correspond with the internal coned surface of the rings F so as to engage with
these, any cast formes can be produced that do not constitute complete cylinders.
as shewn at Fig. 1, the extent of the forme being determined by the position of
the pieces G. The casting of the formes can be effected either from the side sur-
face or in the case of complete cylinders from the end surface of the apparatus.
In the first named case the apparatus is placed horizontal and a casting git as
shewn at C Figs. 1 and 2 is used, the sides C₁ of which one can be folded down
on a hinge, and which are connected by the end walls C2 that are hooked in as
shewn the git is fixed by screws in place of the piece A³. In the second named
case the apparatus is placed upright on a stand H as shewn in the modification
Figs. 7 and 9, and the casting git K1 K2 is fixed on the upper end surface of A
and B the outer funnel shaped part K of the git being formed in two parts for
facility of removal, and secured to the apparatus A, while the inner cylindrical
part K2 is fixed on the core B.
The connecting ring F situated nearest the git K can in this case be formed
with openings through it, as shewn by the modification at Fig. 8, or it may be
replaced by a suitable device which both holds the matrix and also allows the
casting to be effected.
When the apparatus is to be used, it is opened. the matrix M is introduced.
the core B is fitted on the introduced half rings F by means of the handles b³,
and upon it are fitted the other half rings, on which the remaining portions of the

page_text: matrix are then placed. The part A is removed and the casting git C is applied
and after closing up the apparatus it is secured by the stirrups D and screws bl.
The end walls C2 of the casting git having been hung on to the side walls C¹
the casting can then be effected in the same manner as with any other apparatus.
If the matrix is perfectly closed, or if a complete cylindrical design is cast,
the matrix &c. is carefully introduced in the half open apparatus and this is then
closed without removing the piece A³, or if this was previously removed for regu-
lating the matrix, it is placed in position again, and is secured by means of the
clamps turning on pins fi and held by locking latches g Fig. 7. The whole
being then secured in the closed position by means of the stirrups D) and screws
as above described, the apparatus. is placed upright on the base H and the casting
git KK having been fixed on the upper end, the casting of the forme is effected.
In both the above cases, the apparatus is opened after casting, the core B
together with the cast forme and matrix are lifted out of the apparatus, and after
removing the matrix in the usual manner, the rings or caps B are removed from
the core B the latter then collapses and the pieces having been removed from
the interior of the cast forme, this is ready to be used for printing. The core B
is then fitted together again and secured by the caps B¹ for repeating the casting
operation.
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. Stereotype casting apparatus consisting of two or more hinge-jointed parts A'
A2, the interior of which forms a complete cylindrical casting chamber containing
the matrix of the form to be cast and provided with a git, in this chamber a
core B fitted by means of rings F, such core having a central hollow and being
built up of a number of wedge shaped parts held in position by end rings or
raps B, so that on removal of these after casting the forme, the core collapses
liberating the cast-forme, substantially as described.
2. In stereotype casting apparatus such as is above referred to providing between
the parts A and A² a removable piece A³, for facilitating the accurate introduc-
tion and fitting of the matrixes, which piece is arranged so as to be secured in
position when fitted in again after removal substantially as described.
3. In stereotype casting apparatus such as is referred to in the first claim, the
provision of insertion pieces G which are introduced parallel to the axis in the
required positions between the core B and the casting apparatus A, and are
secured by rings F, in cases where the cast forme to be produced is not a com-
plete cylinder, substantially as described.
4. In stereotype casting apparatus, such as is referred to in Claims 1 and 2, the
provision either of a casting git C1 C2 Figs. 1 and 2 to be inserted in place of the
piece A3 for effecting the casting at the side of the apparatus or of a casting
git KK Fig. 7 arranged at the upper end of the apparatus when this is in the
vertical position, substantially as described.
