BIG OPENING FOR INVENTORS.
Suggestions for Articles Which
Would Fill Long Felt Wants
and Find Market,

MN AAAe A'AeAhS"
The practical minded inventor, as
we'll as the one who has but a mod
est income, should always ask him
self these important questions, before
spending his money on models or
patent fees:
First, is the device useful? Second,
does it fill an actual want? Third, if
so, is the device practical and can it
be readily manufactured and mar
keted? Fourth, is there similar ar
ticle on the market already?
AS to the suggestions we advance
below, we believe that they cover all
our requirements. There is positive
demand for all of the devices and il
the correct solution is found, each in
vention will undoubtedly prove a
handsome moneymaker.
Electrical Air Cooler-At the pres
ent time we use fans i'll the summer
to cool" our sweltering humanity.
Fans really don't cool, but simply
stir up the heated atmosphere, and
by causing drafts evaporate the
moisture on our skins. This gives
cooling sensation. Electric fans, how
ever, does not reduce the room tenn
perature to any great extent and for
that reason are makeshifts at best.
We should produce cold lowering OF
the temperature) by some other cleo
trio means. Peltier showed us that
cold can be produced by crossing
bar of bismuth with a bar of anti
mony and sending an electric current
through it in a certain direction. This
is Peltier's cross. Why cannot this
prinoiple-or a similar one-rbe sup
piled on a commercial scale, and ill.,
cidentally make a fortune for its in
ventor?
Electric Insect Destroyer-Every
summer we are exasperated by flies
and mosquitoes. Why not keep them
out of the house or kill them by some
electrical means? Electrically charged
wire netting has been used already,
but it has many inherent faults. AS
a rule such netting cannot be used
on windows as water or moisture puts
the device out of order. Something
more practical is required. Insects
as rule keep away from highly
charged conductors (high frequency
or Tesla currents). Perhaps this hint
will put somebody on the right track.
Electric Toys-There is an i'm
mense market for cheap electric toys.
Something is wanted to keep a boy
amused with good electric toy OPP
Grated by dry cell Years ago we
saw an electric motor that sold for
10 cents and actually ran. 1t was
badly designed and badly made,
otherwise the 5 and 10 cent stores
would be selling 100000 or more of
them year. Here is a rich field
and it matters little if the article can
be marketed for 10 cents or $l-if
the toy is right,
Electric Window Attractors-A
vast field for the clever inventor.
Movable window attractions are in
ever-growing demand Everybody
stops and looks at the least mysti-
flying movable sign or whatnot. Elec-
tricity and magnetism supply unend-
ing combinations and providing the
device is novel and cheap, thousands
can be sold. Every retail store can
use one. Can you supply it? ~
Bell "Softener'-A poor title for
want of a better one. The harassed
modern business man is of late de-
veloping what is termed as the "tele-
phone heart" Every time the phone
rings he starts and if he is very nerv-
Gus he jumps Involuntary. At home
his wife is developing the same
disease. What is wanted, badly, is a
device that will do away with the
harsh, abrupt sound. Something soft"
and mellow that doesn't jar ones
nerves. and at the same time is not
too mufiied, otherwise the calling sig
nal cannot be heard in the next room.
Simply unscrew the gongs and re-
place with your device. Can you fur
nish 100000 at, say, 81 each?-Elec-
trical Experimental.
