Improvements in Typewriting Machines.
I, OTTO FERDINAND MAYER of 4, Charlotten-Strasse, Berlin in the Empire of
Germany, Technologist, do hereby declare the nature of this invention to be as
follows:-
In a typewriting machine of the kind described in my previous Patent No. 1024100
it is desirable that the type-wheel should strike with great force against
the paper, or rather the paper roller in order that several copies or imprints may be
obtained at the one printing.
With this object I have adopted the arrangement of the carriage carrying the type-
wheel, shown in front view in the accompanying drawing.
In this drawing the reference letters employed in Patent 102410 are retained for
indicating corresponding parts.
In this improved arrangement, the carriage b moves by means of lugs don
suitable guide bars c¹ c². The spindle f provided with a ratchet wheel g of the type-
wheel is however, as opposed to the arrangement in the previous patent,_so
connected with the carriage b as to allow of its oscillating to a certain extent. For
this object the spindle f of the type wheel is carried by a frame 8, which is revolubly
mounted on the carriage b by means of screws t. The frame 8 is maintained in an
upright position by suitable counter-weights u.
In this arrangement, if the key lever, which is not shown on the drawing, be
depressed in such a way that the carriage with the rack gearing and the type-wheels
are moved forward against the paper roller k a projection of the frame & comes,
immediately before the type-wheel reaches the paper roller, in contact with a fixed
stop w arranged at a suitable place on the machine frame. By this means a sharp
rotary movement on the fastening screws t is imparted to the frame s, the force of
which movement is increased by the counter-weights . In consequence of this
rotary movement, the type-wheelf strikes with a short and sharp pressure against
the paper roller so that numerous copies or impressions may be taken, simultaneously
if desired.
If the key lever which has been struck he then again released, the frame will return
to its original position owing to the action of the counterweights u.

and by the following statement:-
In a typewriting machine of the kind described in my previous Patent No. 102419
it is desirable that the type-wheel should strike with great force against
the paper or rather the paper roller in order that several copies or imprints may be
obtained at the one printing.
With this object I have adopted the arrangement of the carriage carrying the
type-wheel, shown in front view in the drawings accompanying the provisional
secifi cation.
In this drawing the reference letters employed in Patent 10241% are retained
for indicating corresponding parts.
In this improved arrangement the carriage b moves by means of lugs don
suitable guide bars c¹ c. The spindle f provided with a ratchet wheel g of the type-
wheel is however, contrary to the arrangement in the previous patent, so connected
with the carriage b as to allow of its osciliating to a certain extent. For this object
the spindle of the type wheel is carried by a frame 8, which is revolubly mounted
on the carriage b by means of screws t. The frame 8 is maintained in an upright
position by suitable counter-weights .
In this arrangement if the key lever which is not shown on the drawing be depressed
in such a way that the carriage with the rack gearing and the type-wheels are moved
forward against the paper roller k, a projection of the frane s comes, immediately
before the type-wheel reaches the paper roller, in contact with a fixed stop w arranged at
a suitable place on the machine frame. By this means a sharp rotary movement on
the fastening screws t is imparted to the frame 8, the force of which movement is
increased by the counter-weights u. In consequence of this rotary movement, the
type-wheel strikes with a short and sharp pressure against the paper roller so that
numerous copies or impressions may be taken, simultaneously if desired.
If the key lever which has been struck be then again released, the frame will return
to its original position owing to the action of the counterweights u.
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 typewriting machines of the kind described in Patent No. 10241% the
arrangement of the spindle (f) of the type-wheel (1) in a frame (8) revolubly mounted
in any suitable manner on a carriage (b) and adapted, immediately before the impression
of the type, to come in contact by its lower and preferably weighted end (v) with a
fixed stop (w) on the machine frame in such a way that a rotary inovement is imparted
to it, and the adjusted type wheel is caused to strike with greater energy against the
paper roller () with the object of producing a sharp pressure and enabling numerous
copies or impressions to be simultaneously produced in addition to the original,
substantially as herein before described.
