PROVISIONAL SPECIFICATION.
Improvements in Typewriter Lever Mechanism.
I, ARTHUR CUNNINGHAM MOLL of 11 Queen Victoria Street in the City of
London, Accountant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the mechanism for communicating the movement of
the key lever to the type-bar or lever, and it is especially designed for use where
the type-bar is to have an exceptionally long travel. Where the type-bar travels
through a distance of 180 degrees or thereabouts, the ordinary mechanism will
not be suitable and I prefer to use the following.
The key lever may be of any ordinary and suitable construction and pivotted
preferably nearer the point where it is operated by the finger so as to obtain a
long stroke at the back end and a relatively short one at the front. Connected to
this is a link which may be curved or suitably shaped to clear the pivot of the
type-bar; the type-bar itself I prefer to provide with a spur, arm, boss or
equivalent so that the link may be connected to it at some distance from the pivot
of the type bar, the point of attachment between the link and the type bar
describing approximately a half circle around the pivot of the type bar.
With this arrangement a type bar much shorter than those usually employed can
be used.

COMPLETE SPECIFICATION.
Improvements in Typewriter Lever Mechanism.
I, ARTHUR CUNNINGHAM MOLL, of 11 Queen Victoria Street, in the City of
London, Accountant, 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 invention relates to the mechanism for communicating the movement of the
key-lever to the type-bar or lever, and it is especially designed for use where the
type-bar is to have an exceptionally long travel. Where the type-bar travels
through a distance of 180 degrees or thereabouts, the ordinary mechanism will not
be suitable and I prefer to use that shown in the accompanying drawing which is
a section showing sufficient of a type-writing machine to illustrate my invention.
The key-lever A may be of any ordinary and suitable construction and
pivotted at A' preferably nearer the front end or point A² where it is operated by
the finger than the back end or point A from which the motion is transmitted to
the type-lever B so as to obtain a long stroke at the back end A³ and a relatively
short one at the front A. Connected to this is a link C which may be curved or
suitably shaped to clear the pivot B¹ of the type-bar B, and is in a state of
compression when in operation; the type-bar itself I prefer to provide with a spur,
arm, boss, or equivalent B', so that the compression link C may be connected to it
at some distance from the pivot B¹ of the type-bar B, the point of attachment C¹
between the link C and the type-bar B describing approximately a half-circle
around the pivot B¹ of the type-bar B.

page_text: With this arrangement a type-bar B much shorter than those usually employed
can be used. D represents the platen over which the paper passes in the usual
manner.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In a type-lever mechanism the combination with a pivotted key-lever having
one end longer than the other of a type-lever provided with an arm or equivalent
such as B and connected by the arm and a link such as C with the longer arm of
the key-lever substantially as described and illustrated in the accompanying
drawing.
2. In a type-lever mechanism a key-lever not centrally pivotted the longer end
being the one which operates the type lever.
3. In a type-lever mechanism the combination with the longer arm of the key-
lever of a compression link.
