ELECTRICAL EXPERIMENTER

unted on Anti- Aircraft Cannon
The electric searchlight has been advantageously combined with many different
forms of war machinery in the past
few years of the great international
cataclysm across the sea, but possibly one of the most unusual adaptations of the electric searchlight is
that shown herewith, which illustrates how the English cannon employed for the defense of London
against enemy aircraft, was fitted
with a small searchlight in order to
increase the rapidity and accuracy
of fire. The anti- aircraft gun is
mounted on a tall building or
promontory, or else on a high
powered motor truck so as to speed
rapidly from place to place. Such
a combination spells deadly accuracy of fire, as anyone who has experimented with the electric flashlight pistol will have found, for when the
searchlight or flashlight beam was centered on the target, and the shell or bullet
dispatched, it struck the center of the
spot of light on the target; in the present
case, it would strike in the center of the
beam from the searchlight. It can readily
be imagined with what rapidity the gunners
can "spot" an enemy aeroplane or dirigible and bring it down.
McADOO WOULD ELECTRIFY ALL
RAILROADS.
Director -General of Railroads McAdoo
said recently on his return from a trip
that his observation of the vast resources
of water power during the two months he
had been absent from Washington since
the close of the last bond campaign, had
imprest him with the idea of electrifying
the railroads of the United States. f the
Government were to continue the administration of the railroads of the country
for any prolonged period, he said, he would
be in favor of resorting to the use of electricity just as far as it could be practically
employed.
Director -General McAdoo said that for
the present nothing could be done toward
substituting water -power for coal -produced
steam, but it might come as a plain matter of uczcssity while this war was on.

volume of manufacturing power and then
required to relieve terminal
needs. Ultimately electricity would he
principally employed first of all in simplifying terminal problems.
The fact that the topography of the
country was relieved by its many mountain ranges, all abounding in streams that
would provide power, was a guaranty of
the practical distribution of current in the
sections that were now forging rapidly
forward in manufacturing importance.
Some of the virgin ground of iganufacturing development, such as the South
along the Atlantic seaboard, especially invited the consideration of this plan to relieve the country from the thralldom of
coal mining and shipment, according to
:Mr. McAdoo. He held that even if there
were no such great necessity to conserve
our coal supply. the fact that transportation limits the available power of our coal
would of itself justify transforming many
of our railroads to electrical systems.

in the past would have been scrapped as
hopelessly damaged, are now perfectly restored by the arc -welding process at small
cost and great saving of time.
One large manufacturer, working on munitions, has installed an arc -welding equipment for the sole purpose of making tools
for turning shells.
Ordinarily these tools are made from
high speed steel and cost about $12.00 each.
This manufacturer uses high -speed steel
for the tip of the tool only, welding it to a
shank of carbon- or machine -steel, and in
this manner the tools arc produced at a
cost of $2.00 to $4.00. For some time this
plant has been turning out 240 welded
tools per day, the men working in shifts
of four, which is the capacity of the outfit
