Abstract
Abstract Disclosed is a stator winding apparatus utilizing a uniformly rotating crank member, a connecting rod attached to the crank member, a pivot support for the connecting rod permitting longitudinal sliding motion of the rod with respect to the pivot. A driven member mounted for rotation is connected to the rod by a pin and slot connection. The uniform velocity rotation of the crank is converted into intermittent, non-uniform velocity rotation of the driven member. Rotation of the driven member is utilized to provide the oscillating motion for the winding head without use of a barrel cam as heretofore thought necessary in the prior art.

Claim 1
Independent Claim
205 words
An apparatus for converting continuous, uniform velocity, rotary motion into intermittent, non-uniform velocity, rotary motion comprising: a drive member adapted to be moved at uniform velocity through a circular path, a connecting rod having a pivotal connection to said drive member adjacent one of the rod ends, means establishing an intermediate pivot axis for said rod which permits relative motion of said rod and said intermediate pivot axis but with the longitudinal axis of the rod being required to pass through said intermediate pivot axis at all positions of the rod, a driven member supported for angular motion about a pivot axis, an operative connection between said driven member and said connecting rod permitting both angular and linear relative movement therebetween, whereby upon uniform rotation of said drive member, said driven member is angularly moved about its said pivot axis cyclically with each complete revolution of said drive member through a substantially stationary dwell and a maximum angular velocity with said dwell occuring upon alternate rectilinear alignments of the three points defined by the axis of said connecting rod to drive member pivotal connection, said intermediate pivot axis for the connecting rod, and the axis of angular movement between said connecting rod and driven member.
