AT a
meeting of the ‘Verband Deutscher
Elektrotechniker (Association of Ger-
man Electrotechnicians) the suggestion
was made that the Verband consider the
design and development of artificial |
arms, equipped with electro- |
magnetic seizing and holding
mechanism. The underlying |
idea is simply this: |
The sleeve enclosing the stump of the
arm is provided at its outer end with a
pot-shaped or bell-shaped
magnet, which can be ad-
justed or held in a ball-
end socket, so as to bring
the retaining face of the
magnet to any position de-
sired. The magnet may
then be either clamped tight
or else left movable against
slight resistance. The pot-
magnet is connected with a
current supply by means of
ascrew-plug. Connection is
made by moving some other
part of the body, for exam-
ple the foot, the chin, the re-
maining arm, the dam-
aged arm itself, or even the
whole body.
The pot-magnet makes it
possible not only to grasp
all iron objects, but also to
hold them tight or to lift them and move
them for any length of time. During
these manipulations the connection be-
tween the stump and the object (tool) is
not a rigid, but a movable one. For this
reason the magnetic hand may be used
by all workmen who work with iron tools
or iron articles. Asa
rule, the tool need not
be specially altered or
given a special shape
for the mutilated man, |
since the magnetic |
hand is capable of |
grasping the tool at |
any place, provided it |
is made of iron. |
In filing, for in-
stance, the magnet is |
placed on the outer |
end of the file. The |
file is moved exactly as if it were guided
by a healthy arm; for the magnet can
move relatively to the sleeve. A car-
penter’s plane is provided at its extrem-
ity with a small iron disk and is manipu-
lated in exactly the same manner as any
other plane. Stampings cut out by ma-
chine dies can be removed perhaps with
greater ease than with a normal hand.
Still other grasping movements, for
instance a pinching movement, may be
carried out without difficulty. Even the
delicate closing movement of a pair of
pliers may be effected.
