Mathematical Analysis of the Contact Of Surfaces
in Osclllatng Machinery BY Prot. c. w. Hackey,
Of New York.
The subject Of this paper suggested by newly in
vented printing press which the type bed oscilaed
o centre below II, and cylindrical surface which
70 press It otchlased on centre above. The curved
surface and plane required to be in contact though
out the whole movement without sliding upon each
other.
The mathematical problem consisted in Determining
What curve would be required Tor the transverse section
OF the upper cynnoIc portion also the radius OF the
oecuatory circle OF the curve Tor the purpose OF ascer
tanning whether circular form would approximate su
enty near the true curve Tor the distance IN
an ordnsry type bed Il

fsrentia and integral calculus were Variation only
