The weighted levers of this machine are

the downward half Of each revo utiOn they
fail outward and forward, thus fengthen-
ing The radius of the revolution. on the
upward half Of the revolution the levers
close up and the weights describe an arc
of rotation with a shortened radius. AS
each transverse arm with It's iointed lever
and weight rises a little past the horizon
tai il slides forward and downward, thus
throwing the weight on the opposite end
still further from the center and increas-
ing the turning moment on that SIDE, at
the same time decreasing the moment on
the upward half of the revolution. The
transverse arms are kept in place by
means of small rocking levers which ex-
tend from steadyng arms attached to the
shaft.
After Aldrich had been sent to prison
some of his dupes were still ready TO be
lieVe that there was something in his mo-
tor. They couldn't make 1t go, however,
something was wrong somewhere. So
they sent it to the patent office. The pat
ent Office Is overrun with perpetual motion
machines, and the examiners seldom stop

motor was shipped back TO Bradford. Then
it was sent to the Scientific American Of
flee The Bradford people wanted it taken
apart and looked into; they didn't want to
take it apart themselves, because they
didn't know what internal contrivances
might he secreted in It. The examiners
here looked it over carefully and failed to
find any concealed devices. They said 1t
was the cleverest looking motor they had
ever seen. Rather than destroy the ma
chine, they took an X ray photograph of
the innocent looking wooden base.
The mystery vanished when the X-ray
revealed the silhouette of common,
everyday clockwork. with its big steel
spring extended The gear was connected
with the main shaft of the motor by means
of a small rod extending through one OF
the posts two beve wheels in the top Of

and weights. No wonder a governor and
a brake was needed. The problem Of con-
ccaling the joint after the works" had
been inserted was solved by forming a
bevel joint and making it coincident with
the bottom edge of the base. This was
skiifully done. and the effect was height
enod by making the joining OF the posts
with the base rough. The thing was put
together with artistic clumsiness. The key
holes by which the clockwork was reached
were concealed under The base Of the big
brake. This block. il was found, could be
lifted from the Dashboard, but even then
the two little key holes We're not Of sus-
plcious appearance. for they were made to
resemble worm holes.
1--WE have no doubt whatever" says the
Scientific American, that Mr.. Aldrich be-
lieved that his eXtensible arms, with the
weights huns far out on one side Of the
shaft and drawn snugiy in on the other
side, would not only insure perpetual ro-
tation but in a machine OF sufficient size
would exert a not inconsidcrable number
Of horse power. As a matter Of fact, even
in a frictioncss machine, there would be
no turning moment whatever, and as it
was. Mr. Aldrich found that on starting
his machine n was very quickly brought
to rest by the energy consumed in over
coming the internal friction. If he had
been content as many another unfortu-
nate man had been before him, to consign
his machine to The scrap heap, il would
have been better for him and for his vic
Tins; but. being Of an ingenious and re-
sourcoful mind, and doubtless tempted Of
the devil he conceived the idea Of over
coming tho troublesome friction by means
of concealed clockwork, and. acting upon
the thought, he carefully carved and whit
tied out the wooden bed plate Of the ma
chine and placed therein the springs and
the train Of gears. With perpetual mo-
ton so palpably accomplished, however
Mr.. Adrich saw in his crea ton a means
Of immediate if unlawful gain. Hence,
three things followed: Many simple pco-
pie were relieved OF their money; Aldrich
was given space for repentance within
Auburn prison and the Scientific Ameri-
can Is enabled to point a moral and adorn
a tale. for the benefit Of the all too easily
shared investor"
