page_text: I, ADOLPHUS PROSPER EGGIS of Fribourg in Switzerland, Editor of "La Science
Pratique." 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 :-
My improvements relate to type writers or writing machines and bave for their
object the production of a machine which will write as well capital as small letters,
figures, signs, punctuations and other marks and possesses at the same time great
simplicity, so that it can be sold at a very low price.
1.
In order that my invention may be more readily understood, I have hereunto
annexed two sheets of drawings marked with letters of reference, similar letters
denoting similar parts on the different figures.
"
Figure 1 shows my improved type writer as seen from above and ready to work,
Figure 2, shows the movable printer hereinafter described taken out of the
apparatus and seen from beneath.
Figure 3 shows a longitudinal side view of the apparatus; figure 4 a longitudinal
section along the line W X on figure 1 with the mechanism in the position it
occupies when printing a letter.
Figure 5 shows a cross section along the line Y Z on figure 1.
To a plate A guides B B are affixed in which slides the slide D formed with
bearings for the paper cylinder E. The paper F is placed around the cylinder E
as it is shown by Fig. 5, and held in place by means of a fixed rod G and of a
movable rod G¹. The cylinder E is turned round by means of a button E¹.
A click wheel e and a spring. click e¹ allow the distance through which the
button E¹ is turned to be measured and the space between two lines to be thereby
determined.
A toothed rack H affixed to the slidè D is employed to cause the paper to
advance by a determined span each time a letter or other sign is printed.
The plate A bears to that effect a bracket K with lever and click ¹ gearing
into the teeth of the rack H. Another bracket L also fixed upon the plate A bears
a lever intended to put the click out of gear by pressing the outer end of
downward with the finger as indicated by the arrow on fig. 5, when the slide D is
to be pushed into its guides.

On the plate A three pillars a¹, a², a³, are fixed supporting a plate A¹ provided
with several openings.
also
There is firstly a large, circular opening closed by means of the disc I when the
apparatus is at rest. The said disc or circular shaped plate I is movably attached
by means of a stud bolt i to the frame J hinged to the lower part of plate A¹ by
means of hinges j. The plate I can revolve around the bolt i. A spring
fixed to the underside of plate A¹, presses the frame J as well as plate I upward so
as to maintain the same in the position shown by Fig. 3. The plate or disc I bears
on its upper face two hooks C and S¹ of a peculiar shape and provided with
buttons and S. The lower face of I is provided with one range of types, one
half of which is composed of the capital letters and the figures, and the other half
of the small letters and of the punctuations, as shewn in Fig. 2.
Two spring blades M M affixed to the frame J are provided with inking
rollers mm, which are pressed against the types on plate I for the purpose of inking
the same.
A stud N is also fixed to the underside of the frame J and presses down
the lever K and thereby causes the slide D to advance by one tooth of the rack H
every time the frame J is pressed downward.
The plate A is moreover provided with a circular range of openings O disposed
and formed so as to give passage to one of the hooks C₁ or S¹ when the latter are
pressed downward. Each of these openings is marked with a letter or a figure or
a sign. The position of the hook Ċ upon the plate I is determined in such a
manner as to have the capital letter or the figure with which the opening is marked
in which the said hook is pressed down, printed upon the paper F. The position
of the hook S upon the plate I is determined in such a manner as to have the
small letter and the punctuation with which is marked the opening in which said
hook is pressed down, printed upon the paper F.
The annular shaped opening Q of plate A¹ has no other purpose than to allow
the passage of the hook S¹ when C¹ is pressed into one of the openings O, or to
the hook C when S¹ is pressed into one of them. The opening R placed at the
circumference of plate I allows the operator to provide the inking rollers with
colour when they become dry.
The working of my improved type writer is as follows: if you wish to print for
instance the capital letter A or the figure 5 you take into your hand the button C,
then turn the plate I until the hook C' is placed over the opening marked A or
marked 5, you press the button down and the type A or figure 5 will be printed
upon the paper.
If you have to write the word "April," after printing the letter A as herein last
described you then take into your hand the button S, turn the plate I until the
hook S¹ is placed over the opening marked P and press the button downward.
The stud N then presses upon the lever. k and click and causes the paper to
advance by the necessary distance. At the same time the type p is pressed
downward and reaches the paper as soon as the same is stopped so as to be printed
at the right distance from A, and so on.
When one line is terminated, you turn the button E' so far that the click e¹
catches into the next tooth of the wheel c. Pressing then the lever / downward
you raise the click out of the teeth of rack H and you push the slide D with
paper cylinder E and paper F backward so as to be able to begin another line.
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:
1st In type writers the arrangement of a revolving plate I provided with fixed
types substantially as hereinbefore described and shewn on the drawings.
2ndy The combination of the said revolving plate I with a hinged frame or
carrier J and a spring J¹, substantially as hereinbefore described and shewn on the
drawings.

page_text: 3rdy The hooks C and S¹ with buttons C and S in combination with said plate I
and openings O substantially as and for the purpose hereinbefore described and
set forth.
4thly The inking rollers m m attached by means of spring blades M M to the
frame or carrier J of the said revolving plate I substantially as herein before
described and shewn on the drawings.
5thly The combination of plate A, pillars a¹ a² a³ and plate A' with guides B B,
slide D, paper cylinder E, rack H, bracket K, lever k, click k bracket L and
lever, substantially as shewn on the drawings and as and for the purposes
hercinbefore described and set forth.
