PROVISIONAL SPECIFICATION.
Improved Artificial Hand, Permitting the Automatic Prehension of
Objects.
I, GEORGES CLASEN of Brussels in the Kingdom of Belgium, Surgical Instrument
Maker do hereby declare the nature of this invention to be as follows:-
My invention relates to the construction of an artificial hand as I will describe
referring to the accompanying drawings. The thumb and the fingers of this hand
are articulated and arranged in such a manner as to separate as shewn in Fig. 1 or
to contract as shewn in Fig. 2. This is effected through the action of a disc or
wheel A, which is inserted in the hand. It is fixed on a spindle having a screw B
on one or both of its ends to act on worm gearing on the joints of the thumb or
fingers or both. The fingers and thumb are separated or closed by pressing the
disc A on a table or other surface and causing it to roll backwards or forwards.
The inner surfaces of the fingers and the thumb are cushioned with any slightly
compressible substance, such as india rubber, hair or the like, in order to afford
a better grip of objects taken up.

I, GEORGES CLASEN of Brussels in the Kingdom of Belgium, Surgical Instru-
ment Maker 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 invention relates to the construction of an artificial hand as I will describe
referring to the drawings accompanying my provisional Specification. The thumb
and the fingers of this hand are articulated and arranged in such a manner as to
separate as shewn in Fig. 1 or to contract as shewn in Fig. 2. This effected
through the action of a disc or wheel A, which is inserted in the hand. It is
fixed on a spindle having a screw B on one or both of its ends to act on worm
gearing on the joints of the thumb or fingers or both. The fingers and thumb
are separated or closed by pressing the disc A on a table or other surface and
causing it to roll backwards or forwards. The inner surfaces of the fingers and the
thumb are cushioned with any slightly compressible substance, such as india rubber,
hair or the like, in order to afford a better grip of objects taken up.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is :-
The construction and use of an artificial hand arranged and operating substantially
as described and illustrated by the accompanying drawings.
