This Toy Gun's Projectile Is Driven by Electricity

A ‘TOY gun, which is made of 1/8-in.
brass pipe, makes use of the
movement of an iron armature into the
magnetic field of a solenoid when the
current is applied. Mounted near the
rear end of the pipe is a coil winding
of the usual type. The proportions
shown have been found effective. {The
gun can be made in any size desired so
long as the proportions are kept. In
order to give the appearance of a long-
distance rifle, a wood sleeve is turned
and pushed over the front end of the
pipe and a wood part turned and pushed
over the rear part.
The coil is wound on the space
thus made; but first an iron or steel
washer is pushed over the pipe at each
end of the coil space in order to
strengthen the flux. The winding is
arranged in even layers and shellacked
after each layer is completed; or, bet-
ter still, enameled wire may be used
which will give more wire and con-
sequently more strength to the coil.
‘When the winding is finished a piece
of thin steel tubing is pushed over it,
which bridges between the two wash-
ers, thus ‘completing - the magnetic
circuit. If steel tubing, which is the
best material, cannot be procured, a
piece of thin tin may be wrapped
around and soldered to form a tube,
or else part of a tooth-powder box may
be used. This iron casing is very im-
portant, as the strength of the gun will
be greatly increased by its use. This
tube is also used to support the gun.
As the illustration shows, two brass
hubs are turned and soldered to the
steel tube and mounted in a wood car-
riage. In this way the elevation of
the gun, which determines the range,
may be controlled.
+ The projectiles consist of pieces of
soft iron rods which are inserted at
the rear and held in place
by the hanging piece shown.
‘The gun is fired by depress-
ing the key which connects
the battery, and releasing
it again quickly. It is, of
course, evident that the
projectile tends to move to
the center of the solenoid,
and if the key is not released
at the proper time, the pro-
jectile will either be drawn
back into the gun or re-
tarded in its flight. This
fact introduces an element
of skill into the firing of the
gun.
Reaching the greatest
range is, in all probability, the rea-
son for the great fascination the gun
has had for old folks as well as
young.—CHARLES {ORTON
