Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
711
Professor
Pepper
likewise
constructed
an
imitation
of
Psycho,
under
the
nom
de
théâtre
of
Scynthia.
This
figure,
though
very
ingeniously
contrived,
did
not
confessedly
fulfil
all
the
conditions
of
Psycho.
Cremer
also
introduced
a
whist
player,
which
was
a
huge,
complicated
mass
of
wheels,
levers,
and
elaborate
mechanical
contrivances,
and
necessitated
a
most
careful
supervision
for
a
successful
exhibition.
It
could
never
be
relied
on
for
a
smooth
and
uninterrupted
performance.
A
French
firm
also
constructed
a
whist
player
for
Mr.
Everett,
and
this
eventually
went
to
America.
In
this
figure
the
boy
was
much
better
concealed
than
in
the
one
I
mentioned
before.
One
very
ingenious
solution
of
the
construction
of
Psycho
was
offered
in
November,
1877.
I
partly
reproduce
it--not
because
it
is
a
solution,
but
because
it
will
enable
the
practical
and
ingenious
reader
to
construct
a
figure
something
similar,
although
not
at
all
equal,
to
the
Whist
Player
of
Messrs.
Maskelyne
and
Cooke.
In
Figs.
321a
and
321b
(elevation
and
plan),
the
wheels
E
and
M
have
each
a
train
of
clockwork
left
out
for
the
sake
of
clearness,
which
would
cause
them
to
spin
round
if
unchecked.
M,
however,
has
two
pins,
p
p,
which
catch
on
a
projection
on
the
lever,
N.
E
is
a
crown-wheel
escapement--like
that
in
a
bottle
roasting-jack--which
turns
A
alternately
to
the
left
and
right,
thus
causing
the
hand
to
traverse
the
thirteen
cards.
A
little
higher
up
on
A
will
be
seen
a
quadrant,
B
(see
plan),
near
the
edge
of
which
are
set
thirteen
little
pins.
The
end
of
the
lever,
N,
drops
between
any
two
of
them,
thus
causing
the
hand
to
stop
at
any
desired
card.
The
lever
being
pivoted
at
c,
it
is
obvious
that
by
depressing
the
end,
N,
B
will
be
set
at
liberty,
and
the
hand
will
move
along
the
cards;
by
slightly
raising
it
this
motion
will
be
arrested;
by
raising
it
still
more
the
pin,
p,
is
released,
and
M
commences
to
revolve,
and
by
again
depressing
N
this
wheel
will,
in
its
turn,
be
stopped.
Near
the
bottom
of
the
apparatus
is
a
bellows,
O,
which
contains
a
spring
tending
to
keep
the
lever,
N,
with
which
it
is
connected
by
a
rod,
X,
in
the
position
shown.
