page_text: I, FERDINAND HEINRICH KÜSTERMANN of 75 Prinzen Allee N. Berlin in the
German Empire, machine maker do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention consists in an improved arrangement of type-founding machines so
that the cast letter is not pushed out of a stationary mould as usual, but remains in
the place where it is cast and is liberated by the withdrawal of the mould, whereby
simultaneously a passage is formed in which the letter is subjected to the finishing
process while being pushed down it. By my improved arrangements the construction
of the machine and the different motions for producing the letter are simplified and
for casting letters of any thickness the same mould blocks can be used, a corresponding
thicknessing or core plate only having to be inserted into the machine.
On the sheet of drawings appended hereunto fig. 1 shows part of a machine with
my improvements in longitudinal section, fig. 2 a top view partly in section and with
the upper part of the mould removed, and fig. 3 a front view of the same.
and 5 shew details.

The mould for casting the type is formed of the hardened cast steel blocks i i¹,
likewise hardened cheeks g g', containing the git, the thicknessing or core plater and
the cover block A fitted with the front plate b. The steel blocks with the cheeks g g'
are by means of screws s s firmly drawn against the steel pieces J J which are in
their turn drawn against the angular cover R in order to keep the front facings of
the block i i¹ in one plane and at right angles to the core plate. The angular cover R
and the pieces JJ' are firmly attached by screws R' to the slide D which can slide on
the machine plate M. The core plate r is fixed to the carrier K which is guided by
the parts J J and the carrier K is adjusted and fixed correspondingly to the thickness
of the letter to be cast The steel block i retains its position for casting letters of any
depth and only the upper block is adjusted on changing the core plate. For the
largest size of letters to he cast on the machine the block comes close against the
cover R. When smaller letters are to be cast, a corresponding core plate is screwed
to the core carrier K and the block i is adjusted on the top of the core plate. The

page_text: space left between the block and cover R is filled in with a packing piece h. The
cover block A is fixed to the bed plate M.
After
During the founding the slide 1 with the mould is pressed against the cover block A
by means of the beam lever F connected to the spindle G and by the cain E acting on
roller c. The core plate and carrier K remain stationary, having been previously
adjusted to the thickness of the letters to be cast by means of the screw and fixed by
means of the screw in the fixing K' which is screwed to the bedplate M.
the cast is made the slide D with the mould is drawn back by means of the cam E
acting on the roller e as shown by fig. 1, to a distance equal to the thickness of the
letter, while the core plate and consequently the letter remain in their positions.
The letter thus remains on the spot in which it was cast and is held by the cover A
and the core plater above the passage or channel formed by the withdrawal of the
mould from the cover A.
In this position the letter is acted upon by the pusher a which is actuated by the
eccentric N, the eccentric rod H", the levers H H¹, and the sliding bars T with cross
bard. The downward movement of this pusher a pushes the letter down the channel C
to the finisher, whereby the git is broken off and the cone at the face of the letter
removed by the cutter m. In order to prevent the letter from dropping down the
channel during this process, the cam E by its rotation leaves the roller c as soon as
the pusher a begins to move the letter and thereby the slide D with the mould is
released. The slide is then pressed forward with a light pressure by the springs p p
(fig. 2), which were compressed by the drawing back of the mould, and the letter is
thus held in the channel C.
When the letter has arrived in front of the horizontal channel of the finishing
apparatus, and the pusher a returned to its highest position, the cam E has also
completed its revolution so far that it again acts upon the roller c¹ and presses the
slide D with the mould against the cover block A. By the advance of the slide D the
leiter is pushed into the horizontal channel by the pusher a¹ (figs. 1 and 4) fixed to
the slide D. The next letters pushed into this channel after the next casts propel the
preceding ones and thereby push them past the cutters m² (fig. 4) which remove the
cone at the face of the letters from the other two sides, while the foot cutter f smooths
off the fracture of the git a little recessed. In order that the finishing channel may
be suitable for letters of any depth, its bottom plate g is made adjustable and provided
with a lining plate e held up by springs against the letters (fig. 1). In order to
obviate the necessity of changing the pusher a¹ for different depths of letters, the
pusher a¹ and the end of the plate e are formed with corresponding prongs fitting
into one another (see plan fig. 4). In consequence of this arrangement the pusher a¹
can push letters of any size with the compass of the machine into the finishing
channel.
Simultaneously with the advance of the letters the mould is closed again and thus
made ready for the next cast. After the letters have passed the finishing apparatus
they range themselves upon an angle bracket W attached to the bed plate.
The advantages secured by the improvements herein described and produced mainly
by the arrangement of drawing back the mould and leaving the lotter in its position,
instead of pushing it out of a stationary mould, are that a simple backward and
forward movement of only two parts, that is to say of the mould and the pusher a
suffice for casting and finishing a letter and that for changing the apparatus from one
to another size of letter only the exchange of the core plater and the adjustment of
the upper block i are required.
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, in type founding machines:
Firstly, t
, the arrangement of a reciprocating mould consisting of an upper part J
with adjustable steel block i and a lower part J' with steel block firmly enclosed
between a cover R and slide D and so arranged as to guide securely a core holder K
with core plate for the purpose of making the mould suitable for casting letters of

page_text: different thicknesses by merely exchanging the core plater and adjusting the upper
steel block i, instead of having to exchange the complete mould, substantially as
herein before described and illustrated.
Secondly, the arrangement of a stationary cover block A with facing b and a mould
attached to a reciprocating slide to which the pusher a¹ for pushing the cast letters
into the finishing apparatus is also attached, so that besides the independent vertical
motion of a pusher a only the reciprocating movement of the slide is required, and
that for arranging the machine for different thicknesses of letters only a core plate?
requires to be changed, while all other parts of the machine can be retained,
substantially as herein before described and illustrated.
a
Thirdly, the arrangement of an adjustable bottom plate (e) provided with prongs
at its mouth for the finishing apparatus in combination with a pronged pusher
attached to the slide (D) of the mould, the prongs of the plate fitting between the
prongs of the pusher, substantially as herein before described and illustrated, and for
the purpose set forth.
Fourthly, the combination in one machine of the improvements claimed in the
three preceding claims.
