PARKER TRUCK IS
SHOW SENSATION
Its New Features Attract
Marked Attention in Madi-
son Square Garden.

One OF the exhibits which has at
tracted most attention at the CONNER
cial car show in Madison Square Gar
den Is that of the ak cylinder Parker
truck which IL distributed in New York
territory by the Standard Truck Cor
poration OF New York. sis West Thirty
seventh street.
This truck is made in two ton. three
ton, four ton and Ave ton models. The
Ave ton model Is shown in the Garden
lust to the right OF the main entrance.
il has features which are peculiar TO
itself and which have helped II to win
its high reputation for economy OF OPP
Grafton. sturdiness Of design and de-
pendability on the road. 1t Is no ex-
pertinent as 1t has made good for more
than eight years.
In all the models the motor is the
same the six cylinder, flfty-ave horse
power. three point suspension Continen-
tai. A sealed governor limits the mo-
tor speed to 1,100 revolutions per min
ute and the car speed to twelve or th!r-
teen miles per hour. With the engine
turning at this speed lead pencil placed
on the motor block will remain erect,
proving conclusively the almost utter
lack Of internal vibration which the
constant torque OF the six cylinder mo-
tor produces. AS every truck owner
knows, 1t is vibration which shortens the
lifo of truck. Ignition Is by high ten
elon magnetic.
So slight Is the vibration of this truck
that electric lights have been found to
operate perfectly on It, and Its standard
equipment provides two electric side or
dash lights and one electric tail light
by operated storage battery and West
inghouse generator. The dash lights
are 30 placed that they not only act as
headlights but serve also to illuminate
the motor. thus aiding the operator II
adjustments are necessary at night.
An electric starter also forms part Of
the standard equipment This starter
has been found to add 40 per cent. to
the life Of the motor and to save at
eeast 400 hours OF truck time yearly,
Chat is almost an hour a day, over the
Band cranked truck. This time has real
value in dollars and cents to every truck
owner, particularly in these days of In
Creasing wages.
Few motor trucks are really operat-
ing more than FIVE hours out OF ten and
most drivers let their motors idle Mt
least one to two hours daily. This idl,ng
Is most injurious to the motor. as II
shortens its life even more than when
in gear and under power. Moreover. in
a hand cranked car. whenever the dri-
yer stops or starts the motor he inva-
riably opens the throttle wide In order
to insure a rich mixture Of gas. THIS
results in racing the motor. with conse-
quent damaging vibration.
All this is prevented by the Westing-
house starter on the Parker truck. be-
cause the driver can shut off the gas
Immediately. knowing that hik starter
will function efficiently. no matter wha
charge may be in the cylinders By
preventing idling Of the motor the
starter also does away with much of
the carbonizing which pits the valve
and lessons compression as we'll as SCOT
ing the spark plugs and thus weaken
ing the ignition.
The radiator OF the Parker is a cast
tank assembled in sections. Its mount
ing differs from that OF radiators In
other trucks in that It is attached to
the frame by means OF swivel joints
watch protect 1t from road shocks and
results in practically no radiator trouble
for Parker owners.
One of the main features Of the Par
ker truck is the sturdiness and length
Of it's springs. Its front spring alone is
as large as the rear spring on some
trucks OF equal size Springs are semi
elliptic. both front and rear The front
spring is 3 inches wide and SO inches
long and the rear spring Is 3i2 inches
wide and 60 inches long
The rear, springs have fourteen leaves
each. These springs. made of the best
steel, relieve road strain and vibration
and the truck rides over cobble stones
almost like a touring car.
The rear axle liz built in the Parker
factory In Milwaukee and has Thinker
worm and gear. Under the rear axle
are double truss rods. Radius rods are
so hung that they can swivel in every
direction. This Is a feature found per
haps on no other truck and is one which
every experienced truck driver will ap
preciate
The transmission is geared on a ratio
of 12% to l in high and in ratio Of
1915 to l in low. This combination
enables the truck even with a six tor
any grade upon which traction is pos
sible. The Parker is geared for five
speeds. four of them forward.
Directly behind the transmission or
the propeller shaft is a huge servic,
break with which the driver can stoI
his truck. bearing its maximum load
within an incredibly short dista nee. Sc
effectively does it function. This brak,
is rugged on a drum four inches wild,
and fourteen inches in radius. Tn.
emergency brakes are placed on the real
axle and operate surely and efficiently
As an example OF how sturdily bull
the Parker truck Is without being merel.
massive. one may cite the spring sus
pensions. These are more than ampl,
TO meet any road shock that may b.

The wheel base OF the five ton mode
10 16s inches, The tread at the from
Ia 81 inches and at the rear Is 81 inches
Tires at the front are solid. 36x5. anC
at the rear solid duals, 40x6. The chas

One of the striking features of thu
Parker Is the hydro hoist which is used
for dumping purposes. 1t In made by
the He'll Company OF Milwaukee and |.
rated as twice as powerful as most sim
liar hoists.
Accessibility OF all the working parts
is one of the points which distinguish
this truck. This allows both quick in.
spection and easy fabrication. Through
the Parker trucks simplicity of design
fewer parts than usual are used. thu.
