COMPLETE SPECIFICATION.
An Adjustable Type Founding Apparatus.
I, WALDEMAR GROTHE of 29 Thurmstrasse, Berlin in the German Empire,
Printer, do hereby declare the nature of my 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 an adjustable type founding apparatus by means of which
type of any desired depth and size can be made and is especially intended to
rapidly and readily replace defect type. For this purpose the jaws of the
apparatus composing the mold in which the type is cast, are made of several parts
which can be so adjusted to each other, that the section for the body of the largest
as well as the smallest type is attained whereas a matrix of the letter or type head
is applied to the rear inner side of the apparatus.
Fig 1 of the accompanying drawing is a perspective representation of the type
founding apparatus in opened position.
Fig. 2 and 3 represent in front and rear elevation the adjustable type founding
apparatus.
Fig. 4 is a vertical section on the line y-y in Fig. 2 and
Fig. 5 an elevation of the apparatus adjusted for casting a small type the cover
or plate being broken away.
The construction of the type founding apparatus is as follows:
The two arins a and b are movably connected by the bolt cand carry at their
bifurcated ends a two jaws d and e which move around the bolts d'el. A short
rail or plate is arranged at the lower side of the jaw d and a like rail or plate g
on the upper surface of the jaw e said rails being attached to the jaws by means of
the bolts and nuts. In order to be able to slide the rails fand g backwards
and forwards and thus produce a larger or smaller space between the jaws d, e the
same are provided with slots o as represented in Fig. 1 and 5 through which the
bolts run.
In accordance with the said slots o the rails and can be brought nearer or
removed from each other by the jaws d, e being placed at an incline in the forked
or bifurcated ends a 6, of the arms ab after releasing the nuts de² and subse-
quently screwing up the same.
By means of this double adjustment of the parts id est the rails, and jaws de
the section of the body of any desired type can be attained as is evident from the
Figs. 1 and 5. A plate which can be moved around the fulcrum is so attached
to the front surface of the jaw d that the same will securely close the front
opening to the mold and is provided with an opening for pouring in the molten type
metal & with a bored projection or lug for operating the plate or cover k. The
plate is attached to the rear surface of the jaw d by means of a hinge
serves to hold the matrix m and close the form as shown in dotted lines in Figure 1.
The plate is securely held in position by means of a thumb piece 1.
and
In order to apply the improved type founding apparatus, I proceed as follows:
After adjusting the jaws d, e and the rails to the exact size of the
section of the body of the desired type and screwing up all the screw bolts, the
matrix m of well known paper mass is attached to the rear surface of the mold
beneath the plate and the plate turned so around its fulcrum that the front
surface of the mold is covered and the opening k² corresponds with the interior of
the mold Fig. 4. The mold is now cast full of type metal.
In turning back the plate & the runner or superfluous metal is severed from the
type and on opening the apparatus the type can be removed and employed direct
as type without any further operation.

page_text: In this manner any desired number of type can .be cast. If another kind of
type is desired the apparatus can be readjusted as described above. As the runner
or superfluous metal is severed from the type in turning back the plate I prefer
to use a small metal rod or the like which can be inserted in the orifice or boring
in the lug k³.
It will be evident to all versed in the art that the parts of my adjustable apparatus
can be modified in various ways without departing from the nature of my invention.
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:
and their
1. An adjustable type founding apparatus in which by adjusting the jaws de
movably attached to the arms a band the rails or plates/ type of any size and
kind can be cast substantially as described and shown in the drawing..
2. The combination of the arms a b, jaws de and rails the plates
bolts and fulcrums substantially as described and shown in the drawing.
3. The adjustable type founding apparatus and its parts substantially as described
and shown in the drawing.
