An Improvement in Type-writing Machines.
I, RUDOLF SCHADE, 119, Albrechtstrasse, Steglitz, near Berlin, in the County of
Prussia, Germany, Engineer, do hereby declare the nature of this invention to
be as follows:-
A type writing machine, whereby a transmission plate, through which the type
rods go free, effects the displacement of the paper carriage.
Now according to the invention and in order that my said invention may be
fully understood, I will proceed to explain the same with reference to the accom-
panying 2 sheets of drawings, in which;
Figure 1 is a side view of the transmission plate,
Figure 2 is a top view of the same.
Figures 3 and 4 are sections of a type writing machine embodying my. invention
and to better show the arrangement and relationship of the parts.
In the figures the same part will be found designated by the same letter or figure
of reference.
A designates the type rods.
B the framework of the machine.
C the upper and the lower segments of a sphere, in which the type rods are
guided.
D the paper table.
F the carriage rack.
K the arm connected with the transmission plate.
k the elastic piece set on K.
H the striking bar.
L the guiding shaft.
P the transmission plate.
Q the pressing piece.
The machine is to be used as a type writing machine for printing or engraving.
The machine works as follows.
On pressing down a typerod A the transmission plate P gets pushed by the
pressing piece Q, which is connected with A, and at the same time the engagement
mechanisme for the carriage rack of the paper carriage is set to function by the
arm K.
The typerods A are guided in the upper and lower segment of the framework B
and go free through slots in the transmission plate P, so that the lower end of
the typerods with the types can be brought to contact with the sheet on the
paper table D by pressing on the head of the typerod.
The transmission of the lift of the transmission plate P can be done in the
following manner.
If the transmission plate is elevated the arm K is pushed through the space
between two teeth of the carriage rack F, whereby the elastic piece k takes the
position shown in the drawing below the Figure 4.

page_text: If the transmission plate is raised the elastic piece goes in the next space and
the carriage is pushed by pressure in the direction of the arrow until k strikes
against the bar H.
The guiding shaft L can be put also for example in the position of the arm K
and as well the transmission plate can have instead of the round another form for
example square.
An Improvement in.Type-writing machines.
I, RUDOLF SCHADE, of 119, Albrechtstrasse, Steglitz, near Berlin, in the County
of Prussia, Germany, Engineer, 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:-
This type writing machine is of that class of machines in which the types are
secured to suitable rods and my invention concerns also a particular system of
displacement of the carriage which produces a systematic arrangement of the
letters and consequently a regular print, which can be executed much more quickly
than with type-writing machines actually in use.
This machine also provides the means of obtaining several identical copies and
different organs are arranged to allow the optional intervals between the lines
to mark the paragraphs and for all the other requirements.
In the annexed drawings, filed with my Provisional Specification.
Fig. 1 is a side view of the interval plate.
Fig. 2 is a top view of same.
Fig. 3 is a transversal section and
Fig. 4 is a transversal section of my improvement.
In the different figures the same reference letters denote identical parts.
A shows the type-rods of the machine; B the body; C the two metal hemi-
spheres in which the type-rods are guided; D the table upon which the paper
is placed; F the rack of the paper-slide; H the slide forming one piece with the
body and upon which the paper-carriage slides; K the catch arrangement con-
nected with the interval plate and which works the paper-carriage; P the interval-
plate which moves the paper carriage by means of the catch arrangement Kk;
L the guide of the interval-plate; Q the sockets arranged upon the type-rods and
regulating the course of the interval plate; R the spring bringing the lowered
type rods back to their normal position; T the keys corresponding with the
different letters of the type-rods, these keys being very conveniently placed.
This machine is used for producing printed or engraved matter and works as
follows:
When one of the type-rods A is lowered, the socket Q fixed to a suitable part
of the rod, causes the interval-plate P to advance with its guide L and the interval
plate in its turn causes the paper-carriage to advance through the intermediary
of the catch mechanism K which gears with one of the grooves of the carriage
rack F.
The type rods A are guided in the metal hemispheres C fixed at the top and
bottom of the body B and passing freely through the interval plate P so that by
exercising a pressure upon the heads of the rods, the types which are at the
bottom end of the rods successively stamps the paper through the printing ribbon
(not shown in the drawing) which passes above the table D and is provided with

page_text: suitable and known mechanism to strech the ribbon and displace it longitudinally.
The course of the interval plate P is transmitted to the paper carriage in the
following way:
At the displacement of the interval plate P, the arm K connected with this
latter is slipped through one of the grooves of the rack F, whilst the elastic
tappet then occupies the position indicated in Fig. 4 and admits the carriage
advance slightly parallel with its axis after the printing of each letter.
When the plate P moves backward the catch is placed with its tappet k in one
of the following grooves of the rack and the carriage, owing to the pressure which
is produced in the direction of the arrow, is displaced until k rests again in the
slide H.
The guide L may also be arranged sideways for instance in the position of the
arm K and the interval plate P instead of being round may also have another
shape for instance square.
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. A type writing machine, whereby an interval plate, through which the type-
rods go free, effects the displacement of the paper carriage.
2. In a type writing machine the combination of type-rods guided in two
hemispheres, a paper-carriage with rack, a slide part forming one piece with the
body and upon which the carriage slides, an interval plate with guide and through
which the type-rods pass, a catch mechanism connected with the interval plate,
sockets arranged upon the type-rods and regulating the course of the interval-
plate, springs bringing the lowered rods back to their normal position, the said
interval plate causing the carriage to advance through the intermediary of the
catch mechanism which when the interval plate is displaced, fits into one of the
grooves of the carriage rack and admits it to advance parallel with its axis in a
corresponding quantity to the length of the sockets arranged upon the type-rods
substantially as and for the purpose set forth.
