AUTO NOTES


erican Motor league II is estimated that
the number OF automobiles in use in the
United States is about 81, 900 and is in
oreasing at the rate OF 1900 TO 1900 per
month
Prof. r. C. Carpenter OF the depart
ment OF experimental engineering OF Cor
nell and Prof. Frederick Remsen Hutton
or the department OF mechanical engi-
neering at Columbia have joined the AM
erican Motor league and have been ten
derec appointments as members of the
league national committee on technics
Ar automobile has at last been devised
which meets the approval OF the farmer

a strong, single cylinder engine OF about

most efficiently for many of the purposes
Of the former where power and tractive
force are required. 1t will haul a double
furrow plough twice as fast as four
horses, and unlike the horses, does not
give out from fatigue at the end OF five
or six hours. II can be used for hauling
heavy loads along the highway, or 10
drive threshing machine and is, in
short. very complete combination OF
portable and traction engine.
Some interesting experiments have
lately been made by the committee on
technics Of the American Motor league
to determine the approximate pressure
required TO force air inward through an
ordinary valve while Initiating the pneu-
matte tire.
These experiments have developed the
fact that a force OF from 10 10 40 pounds
Is required, depending on the construc-
ton OF the valve; this being the force
necessary TO overcome the resistance OF
the valve, independent of the back pres
sure OF the air within the tire The
pressure needed To force air through the
valve eliminating the resistance due to
the air within the tire) is constant while
the pressure In the tire varies as the tire
Is pumped Chairman Duryea OF the A
NJ. L. committee on technics believes
that the double work thus imposed In the
Initiating OF a tire might he largely avond-
ed by an improved form OF the valve.
The attention OF the National assocra-
ton of automobile manufacturers has
been directed 10 this question and point
Is hereby raised which the valve makers
may proftably consider.
