The Warner Auto-Meter
The fine amounts to little—it's the hours of delay, the inconvenience and possible humiliation for you and for
those in your company that try the patience and spoil the pleasure of the whole trip. All this can positively be
avoided by equipping your car with The Warner Auto-Meter
(Registers Speed and Distance) This little instrument always tells the truth. It registers
with ABSOLUTE ACCURACY from 1/4 mile to 60 miles per hour. It attaches to any Automobile made.
Without it you never know your exact speed — and the temptation to go. a little faster and a little faster is
almost irresistible—you know how it is. And you know, too. what happens to you and your party when you think you
are going 8 miles an hour and the Policeman's stop watch says 15. Don't guess yourself into trouble—KNOW and keep
out of it. The Warner Auto-Meter iS your salvation. And it's your ONLY salvation.
 Because the Warner Auto-Meter is the only speed indicator
which is sensitive enough to be absolutely and unfailingly accurate at speeds under 10 mile's an hour. Because
it's the only one which works perfectly in all positions and at all angles, on rough roads or smooth, up hill
or down. Because it's the only one which changes with the speed alone and in which the indicator does not
dance back and forth from the jar of the car. The Warner Auto-Meter is the only speed indicator which is
actuated by the same fixed, unchangeable Magnetism which makes the Mariner's Compass reliable FOREVER under
all conditions. No one else can use Magnetism to determine the speed of an Automobile, though it's the only
positive and sure way Because there is just one way in which Magnetism can successfully be used for this
purpose and we have Patented that way. There is nothing about the Warner Auto-Meter which can give out, or
wear out, or get out of adjustment. It is the only speed-indicator made without cams, plates or levers, and in
which there is no friction. Friction wears away the cams and levers in other speed indicators, which are
necessarily so small that 2-1000 of an inch wear will throw out the reading from one to five miles per
hour.
One Warner Auto-Meter will last a lifetime. It is as sensitive as a Compass and as Solid as a
Rock. Otherwise it couldn't stand our severe service-test, which is equivalent to a trip of 160,000 Miles at 50
Miles per Hour on Granite Pavements Riding Solid Tires.
The practical Warner Testing Machine is shown in Fig. I. The wheel connection of the Auto-Meter is attached to a
shaft running
200 revolutions per minute. Across this shaft lies a plank which is hinged at one end and has the Auto-Meter
attached to the other. Brazed to the shaft is a knob of steel, which at every revolution "bumps" the plank, giving
to the Auto-Meter 200 shocks per minute while it is showing a speed of 50miles per hour.
Each one of these shocks is more severe than would be suffered in an entire season's riding. After running 10 hours
a day for THREE MONTHS, actual tests show the Auto-Meter to be recording the speed with the same accuracy as at
first within 1-1000 of 1%, or less than 6 inches per mile.
No other Speed Indicator on Earth could
Stand this Test.
This is why we sell each Auto-Meter on a
10 YEARS GUARANTEE
and why we gladly renew any Auto-Meter (which has not been injured by accident) if the Magnet (the HEART of the
instrument) is less accurate than 140 of 1% af ter 10 years use.
We will gladly tell you more about this wonderful instrument if you will write us, If you write TODAY we will send
you something every motorist will prize—our
Free Book—"Auto Pointers."
