Class Information
Number: 74/567
Name: Machine element or mechanism > Elements > Cams
Description: Elements comprising a rotatable, oscillatable, or reciprocable machine element (usually a plate or a cylinder) having a surface or a groove formed therein of predetermined contour which will impart a prescribed motion of reciprocation or oscillation such as generally cannot be obtained by gear wheels or link motion, to a follower slidably contacting with such surface or groove.
