sons: We found that in order to
make the axle shaft assembly, it was
necessary to square it or to make a
squared slip joint on both ends Of
the axle shaft.
These joins must. fit loosely enough
that they could be connected or dis
connected by forcing the shaft into
the axle without the aid of hammer
or other tools
We found that in short time these
shafts would wear the square joints
in the differential and in the hubs Of
the wheels owing to the action OF
action OF the breaks and the con-
stant tendency of car on level
road to run ahead of the engine. By
that we mean there is constant
pulling and pushing influence ex-
erted in the axle while the car ia
being driven over comparatively
level road. This soon caused the
spokes in the wheels to become loose,
owing to the fact that when the
clutch was applied there was GER
tain amount OF slack to be taken up
before the power could reach the
wheels. This caused very severe
jar at the bast Of the spokes every
time the car was started. also every
time the brakes were applied. The
only way this could be removed or
taken out was to replace the worn
parts inasmuch as it was impossible
II Therefore, we fkel that by Ieyins
the shafts tight into the ditferentail
and in the hub of the wheel, we have
eliminated 90 per cent of the trouble
which is experienced with the full
floating type OF axle and inasmucr
as the danger of breaking the shaft
is entirely overcome by the floating
feature, we cannot see In what in
stance it will ever be necessary to
move the shaft itself. ~
The construction and materials in
the Maxwell rear axle are, we believe
superior to any other type and Of suf-
ficient size for this weight car.
1t might be we'll to mention in this
connection that the number OF full
floating axles manufactured last year
decreased IA per cent over, the num-
per cent is all in favor Of the three.
quarter floating or the Maxwell type.
You may ask why the Maxwell diff
ferential housing appears to be small.
1t is possible to use one OF two
admittedly best materials in the build
ing OF the rear axle housing-pressed
steel or malleable iron. Pressed steel
is a heavy form of sheet iron and
when used in the manufacture of an
axle housing, it must be used in
sufficient bulk to sustain the load re-
quired. Malleable iron is a special
grade of iron cast and then annealed,
leaving the strength of the iron with
out the brittleness and toughening
the IRON to- a great extentssf allowing \
the use of 2 much smaller and lighter
housing This is the material used
in the Maxwell differential housing
tubing, completing the rear axle
housing from differential brake sup
ports. II the rear axle housing is
built of pressed steel and it is built
strong enough to carry the load, you
will find that the case is of such
size that it requires Is or IS pounds
of grease to fill it, Then again, you
will find upon examination of the
axle after a seasons use that prac-
tically all the grease which you or
iginally put into the axle is still un-
used and has proven of absolutely no
lubricating value.
This is owing to the fact that the
gears when driven in high rates OF
speed throw Off what grease may ad.
here to them and tend to pack it
tighter into the recesses of the case.
We cannot advise the use of a
hard grease in our axle because we
find that in cold weather when the
grease becomes about the consisten-
cy Of soap that the gears get prac-
tically no fabrication. After making
one revolution trough is cut by
their teeth through the grease and
from then on the gears run almost
without fabrication.
However, in the pressed steel type
axle, it is impossible to use any
other form of fabrication than hard
grease. 1t is not possible to hold
oil such as we use, 600-W steam CYL
inder. therefore it is necessary to re-
sort to the heavier and less efficient
pint of 6O0-W steam cylinder oil will
give adequate fabrication because the
gears at no point in the case ever
have more than one-quarter inch
clearence. This means that in zero
weather there is just as much lubri-
cation of the axle as there will be
on the hottest summer day
HYATT BEARINGS.
Occasionally people ask US why we
do not use this or that make OF BEAR
ing throughout our car. We could
doubtless equip the Maxwell with
other kinds of bearings as cheaply as
we can with Hyatt However, it is
not a question of pride, simply a
question of what We find to be the
simplest and most efficient form OF
bearing, and that is the bearing we
use-a Hyatt flexible roller.
Owing to the construction Of the
Hyatt bearing, the rollers, which are
in reality ground coil spring
hardened. absorb all the acute
shocks, jars and vibrations and do
not transmit this to the vital parts
of the cars mechanism Excessive
load is absorbed in the roller by
lengthening. Bearings with solid
