The Oiling System

pump HCNh"'i' SBioh
type. A single large plunger pump is driven from the
cam shaft through an eccentric. 1t delivers oil from the
oil reservoir TO the three main bearings of the motor, also
to the face of the cam gears. This oil then collects in
partition reservoirs in the bottom of crank case, and is
maintained at a constant level. The connecting rods dip
ping into this oil cause a fine spray, which lubricates the
cylinders and piston. The amount reaching the cylin-
ders being governed by splash plates. We have in this
oiling system no outside pipes or connections to get loose
or leak; no stufing boxes on he pump to require atten-
ton: no additional driving gears to operate the pump: no
adjustments except those made at the factory when the
motor is assembled. We have self cleaning pump, which,
instead of drawing all the PARTICLES of lint and dirt into
the protecting screen by steady suction-as in a gear
pump-keeps the screen clean by discharging at least one
half of its capacity against the screen at teach stroke. We
have also, instead of the large oil reservoir holding two to
three gallons, an oil reservoir holding three quarts. This
is advisable since it eliminates the trouble arising from SO
large Quantity OF lubrlcatlng oil becoming very dirty
and full of carbon deposits. The addition of fresh oil
every $50 to 300 miles is far preferable to a larger quantity
at longer intervals. Particular attention is paid to
making the motor oil tight, and eliminating the loss of
oil and the attendant flthiness of the motor. The outside
main bearings have return oil leads, as have also the mag
neto and pump shaft. The valve plunger guides have re-
cesses at the top for collecting oil and returning it to the
crank case, and also have protecting caps carefully fitted
to keep the dirt out and the oil in. phe1notor has only a
single grease cup-located on thetdh,
Water Pump The water pump is of the centrifu-
gal type, very efficient and access
ible. 1t is driven from the magnetic shaft.
Fan The fan is mounted on ball bearings and is driven
by rs inch fiat endless belt. The belt adjust
ment is very convenient and positive.
Valves The valve lifters are all adjustable and
have hard fiber inserts to deaden the noise.
Valves are of large diameter, bevel seated, 80 per cent
nickel steel heads, electrically welded to cold rolled
round steel stems.
Fly Wheel Fly wheel j? Of ample ed diameter sanede5 to secure e
fan blades to assist in keeping the motor cooled and re-
moving the dead gas from under the hood.
Clutch Type-The clutch is of the multiple disc type.
Disc-The discs are hardened steel and phos-
phor bronze. Steel discs are carefully ground after hard
ing.
OnerafiOn The clutch is provided with a large ball
thrust bearing to take the thrust open
ing. A single spring, easily adjusted, provides the neces-
sary closing pressure on the discus. The whole clutch is
so designed that there is no end thrust on the crank shaft
when In or out. Special attention has been paid to Sc
curing a clutch that releases instantly and engages with
out chattering or taking hold too severely. 1t has a posi-
tive release, due to the fact that the plates are positively
dragged apart by the act of opening the clutch, not left to
separate by the uncertain action of numerous small
springs. Special attention has been paid to securing very
large surfaces of contact between the edges of discs, thus
eliminating the rapid wear of the plates and the rafting
do to looseness.
Connection to Transmission The clutch
transmission is through a double universal joint of very
liberal proportions completely encased and packed in
grease. This joint is of the full universal type, not the
ordinary squared shaft with loose fitting sleeves and con-
Seouent hack slack.
