Improvements connected with Printing Type.
We, OSCAR MAMMEN, Manufacturer ROBERT HAGELMOSER, Merchant, ROBERT
Mosic, and EMIL MOSIG Manufacturers, all of 66 Jerusalemerstrasse, Berlin,
Germany, 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 :-
The object of this invention is to form printing letters or type, which for the
purpose of economy in weight have only half the height of the type hitherto used
and are provided upon their under surface with grooves or ribs extending over the
whole width of the type, being moreover placed upon a movable base in order to
attain the necessary height, required for printing, the upper surface of this base is
furnished correspondingly with the under surface of the type with ribs or grooves,
the dimensions of which agree with the stems of the letter or type. These notches
or ribs (which are made parallely to the wide side of the type in order to be able
to compose the latter in the same manner as with the type hitherto used, that is to
say, from the left to the right) have such a form as to be connected with the base
by simply placing the type on the latter while the said type can be separated from
its base by simply picking it up therefrom.
In this manner, corrections can be made in the middle of the matter after slightly
loosening the same by merely removing the wrong type and replacing it by
the right one without having to shift the type adjoining or that placed above
or below.
Owing to the bases remaining in their position, this matter cannot become
intermingled which would be the case with the ordinary type when it is desired
to remove a few letters for the purpose of exchanging them. The bases of the
new type may be made of any suitable length, their breath in this case being
equal to the width of the type; they are however preferably of such a length as
to be able to receive the several letters required for a line for instance. To
compose a line, one or more bases could be used, that is to say, that by using such
bases, lines of any suitable width could be composed.
When the base is as long as the line, any required position may be given thereto
by adjusting the bases without the risk that the letters may be mixed.

In the accompanying drawings are shown in side views various manners of placing
he letters upon their respective bases.
Figure 1 shows a type a provided centrally upon its under surface with a straight
groove extending in the direction of the width of the type and in which enters a
ib b' projecting from the upper surface of the base b. This rib b holds the letter
r type a sufficiently to prevent the same from shifting in the direction of its stem
e. upwards, while at the same time supporting the same against any possible flexion
f the central grooved part of the type, when printing.
The base may be formed of several parts 62, 63, instead of one only as clearly
hown in Figures 2, 3, and 4. Figure 5 shows a type a, which instead of a groove
provided with a straight projecting rib a' entering a corresponding groove of the

igures 6 and 7.
Instead of a single rib b', the base may have two or more ribs b¹, as shown in
igure 8, which enter corresponding grooves of the type. The reverse arrangement
own in Figure 9 may also be used. The leads or

all cases according to the shape of the type. For instance, Figure 10 shows such
a space furnished with a groove, while Figure 11 shows one provided with a
lower rib.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The formation and employment of printing type which may be interchanged
without disturbing the matter above, below, or adjoining the same, and is
connected for this purpose by means of grooves or ribs formed on their under
surface and extending over the width of the same with a base having a corre-
sponding form, of variable length extending in the direction of the line to be
composed, and the same stem as to give the required height for printing, while its
grooves or ribs afford the necessary hold or grip to prevent them from commingling,
as set forth.
