AUTO NOTES

from statlstlcS compiled by the AM
erican Motor league. 1t Is estimated that
the number OF automobiles In use in the
United States is about $1,000 and is n
creasing 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 engl-
neering at Columbia have Joined the Am
erican Motor league. and have been ten

Some interesting experiments have
lately been made by the committee on
technics OF the American Motor league
TO determine the approximate pressure
required 10 force ar inward through an
ordinary valve while initiating the pneu-
matte tire.
These experiments have developed the
fact that force OF from Is TO 20 pounds
is required, depending on the construc-
tion 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

that the double work thus imposed I'm the
