Off a spark SUFFICIENT to light a gas stove
or an incandescent mantel flame. This
little implement can be produced very
cheaply.
A well-known writer of music has per-
tected a typewriter which will write
musical scores. A working model has
been tried out, and it is claimed that
sheet music no more will need to be pre-
pared by the laborious methods of the
past. One would think that as many
typewriters as there are on the market
today, there would be but little incentive
to inventors to bring out new ones. Yet
as a matter of fact. almost every week
witnesses the granting of from two to
a dozen patents for new ideas in type
writing machines.
The students of geometry and allied
sciences will welcome an invention lately
perfected by a school boy of Oakland,
Cal Is Is a blackboard compass for
gaomaSysaal operations. One leg Of the
compass mas a small pneumatic suction
cup w.Lch clings to the blackboard
wherever placed. A piece of chalk, which
may be adjusted by the use of screw
terminates the other leg of the compass
The baggage smasher has forced the
inventor to the necessity of evolving a
trunk which Is proof against the dam
ages incident to travel One or the
methods used to circumvent the baggage
smasher Is an indestructible trunk whose
life is insured by the manufacturer. An
other trunk is made round like a drum,
so that 1t can be rolled instead of thrown
around Another trunk inventor has
placed extension legs upon his bid for
popular favor. so that the trunk may
serve as a wardrobe while not in transit
Another invention Of interest to women
Is a brace for drying the hair. This brace
is attached to the shoulders, and keeps
the hair we'll scattered while drying. An
automatic alarm to prevent the burning
of the contents of the housewives pots
and kettles is another idea upon which
a patent has been issued. 1t is so ar
ranged that whenever the water in the
kettle runs low a bell is rung. A lock
for the milk bottle has been patented
lately. It holds the empty bottle Sc
curely, and is released by the milkman
who places the mornings delivery Of milk
in it's stead.
AS the summer approaches, the country
will appreciate more and more the ge-
MUS of an American citizen who has at
tached an automatic breeze maker to a
rocking chair This invention consists of
a fan in a large tube, the upper end of
which terminates in a haring mouth like
an automobile horn. When the occupant
of the rocker to which IT is attached.
rocks back and forth, the fan in the
tube is made to revolve rapidly, and
summer breezes may be made to order
thereby.
A patent has been issued for a swim
ming machine which ought to commend
itself to the bathers at our seaside re-
sorts The machine consists of a large
breastplate to which is attached a pair
Of cranks to be turned by the swimmer.
These give motion to a propeller and in
this way the swimmer may navigate at
will. AS there is an air chamber in the
machine, there is not the slightest dan
ger of drowning while using it.
Many thoughtful people believe that
the power OF the future will come from
the wave engine and the solar engine.
A new wave motor has just been in
vented. 1t consists of a push truck run
ming on an inclined track down the beach
into the sea. There is a very large tail
board attached TO the truck, and as the
oncoming wave rushes upon the beach, it
drives the truck up before IL with. great
force. AS the truck speeds forward, 1t
strikes a piston which forces air into a
compressed tank on the shore. When the
energy of the wave is spent, the truck
runs down its incline into deep water
