Motion pictures without an operator
to handle the projection machine, to
rewind the film, to adjust the reel.
and to do all the other things hereto
fore required of an expert attendant
Motion pictures merely by swapping g
on the current from an ordinary cleo
trio light socket. or by dropping a
coin in a slot and releasing clock
mechanism. Motion pictures in day
light as well as in darkness.
This means motion pictures in the
home, in the schoolroom, on the lee
ture platform. in church, in hospitals,
in hotel Hobbies, in railway stations.
in shop windows, in offices. in sales
rooms, on board ships, as they have
never been known before.
1t means visual education as 1t was
dreamed by Thomas A. Edison more
than 80 years ago, when he was doing
work that made possible that modern
marvel, the motion picture. and as 1t
was envisaged by him when In re-
cent interview in Golfers he predict
ed that within 10 years textbooks rs
the principal medium of teaching Will
be obsolete as the horse and carriage
are now. IT believe that in the next
| 10 years visual education-the I'M
parting of exact information through
the motion picture camera-win be q
matter of course in all of our
schools" the wizard said in this in
terview THE printed lesson Will be
largely supplemental-not para
mount."
And all this is no longer a dream.
but is a practical reality as the result
of the genius of a young man from
Wisconsin, who has perfected self
operating continuous motion picture
protector. The Government has set
the seal of its approval on the fnven-
ton by purchasing machines which
are to be used in the educational work
of the various executive departments,
such as the Indian Schools of tho In
| terror Department and the Bureau OF
Extension Of the Department OF Agrf-
culture, and possibly by the Depart
ment of Commerce and by the Ship
ping Board, as educational and enter
| tainment features on board ships OF
American lines. Prominent educators
are planning to introduce the ma
chimes into the classrooms OF public
schools and colleges. and business men,
who are always about three jumps
ahead OF everybody else In utilizing
| new ideas, are already using them in
numerous commercial ways.
Product of Twelve Years Work.
William C. Raedeker is the inven-
| tor, and his invention is the product
of IL years of hard work. However
Mr.. Raedeker bids fair to have
| more enviable experience than has
| been the fate of many inventors, fol
he is only in his 30th year. He
will not have to wait for success un-
/ til his eyes are so dim from age thai
he can scarcely recognize 1t when II
comes Moreover, he is assured OF
/ his full share of the financial rewards
of his genius.
! The distinguishing feature of the
new protector is an ingenious mocha
nism by which the film, as 1t un-
winds to be projected. rewinds into
the original reel, which is, thus con-
| stantly of the same size. Thus, too
| the film is projected continuously
over and over again, as long as the
electric power Is turned on. Instead
of the usual 35 millirneter film, the
film used Is the Eastman safety stand
ard 16 millimeter film, which, IT II
| claimed, will reduce the cost Of prints
40 per cent. 1t is also claimed that
| the method by which the film IL
moved, Instead of being stepped for
ward frame by frame, prolongs the
| life of the film many times and re-
suits in further marked economy.
| Pressing a button starts the pro-
jector and no further attention Is re-
quired until 1T is desired to stop 1t
Should the film come apart, due tc
| improper patching. an automatic mer'
curry switch instantly stops the pro-
| jector. No special wiring Is required
as sufficient electricity is supplied from
an ordinary lamp socket.
Small, Light and Compact.
The protector Is small, light and
compact. 1t is inclosed in box, sirni-
lar to a travelling mans sample case
about Is inches long, slightly les.
than that in height, and about
inches deep. The moving picture 1.
