EASY WAY OF LUBRlCATION

The reason you feel completely tired
out after a days ride in n car-or
on the other hand, thoroughly re-
freshed after a similar trip over prac-
tically the same road in another car, is
due to a difference in the action of
the springs of the two cars, says Clyde
Fl. Pratt, president of the Cleveland
Automobile School company.
The most important part of the cars
mechanical construction as far as the
riding qualities are concerned is the
springs. If the reader will take the
trouble to look at the springs of vari-
u car he Cor she) will note that
there are a number of general types of
springs. These may be classed under
various names, among them full-ellip-
tic, semi-elliptic, three-quarter elliptic,
cantilever and platform springs being
the most common.
How Springs Are Made.
All springs, regardless of their type,
r made up of a number of separate
layers Of fiat pieces of spring steel
placed one above the other, short
pieces being in the middle and the
longer ones extending through to the
eyes Of the spring. The spring is con
nected to the frame by means of a
spring shackle which is fastened to the
end of the spring by a spring bolt
through the eye.
h By watching the springs carefully
when someone else is lettering the a
up and down you will notice that these
separate leaves slide on each other in
stead of simply bending as most peo-
pie suppose. In order to keep the
vibration of the axle from being trans
mitted to the body of the car it is nee
essary to see that the spring leaves
slide easily on each other, and in order
for them to do this there must be n
film of oil between the separate leaves
through their entire length.
Without this Oil film these springs
cannot slide without excessive friction,
which means hat they will not bend
properly and the spring action instead
of being smooth will be stiff and jerky,
with the result that the car will ride
hard and the springs are more liable
springs can be traced to a lack of
proper fabrication of the spring leaves.
Easy Way to OIL.
An easy way to oil these is to put a
lifting jack under the body of the car,
so that the weight will be taken off the
springs. The spring leaves r then
easily separated by means Of a screw
driver or a small chisel and a little
graphite in oil is easily inserted,
Graphite is usually used with the oil
In the spring leaves, because the graph
ite does not work out IS quickly as the
oil alone would.
Many Spring oilers.
There are many different kinds OF
spring oilers on the market. Some of
these are good and others r good
only because the spring needs oiline
and these help to call your attention
to II. The spring bolts must also be
oiled practically every day or they
soon wear 80 the springs work hard
and then at an unexpected moment
break, allowing the al to drop down.
The market also offers many auxil.
larry springs and various shock absorb
ers which viii very often make quite @
difference in the riding Of the car. But
with the instructions that come with
all of these various attachments you
win find that one of the very impor
TINT items which they bring out is to
have your springs thoroughly oiled OF
CREASED before applying the spring
sustaining device.
: Az you travel around In various
makes Of cars you will find TINT It IL
not so much the make Of spring or the
type Of spring which makes the car
ride easy as 1t is the proper care anc
fabrication Of the springs. This more
than anything else will keep your
springs from breaking, making your
a ride easy, cut down your gasoline
consumption and prolong the life o,
the car and tires.
