Suiter Swantz IP takes a look back at past inventions and inventors with our Patent of the Day.
On this day in 1955, Charles M. Palmer, was granted U.S. Patent No. 2,712,317 for an EYELASH CURLER.
An excerpt from the patent states:
This invention is directed to eyelash curlers and more particularly to the front component of a rubber pad clamping jaw having its rear component slidably guided by spaced vertical shanks of a wire frame to which a crank portion of an actuating handle is pivotally connected and also operatively associated with the rear component of the jaw to actuate the latter on displacement of the handle towards or away from an actuate bar anchored to the upper portions of the shanks. Specifically hitherto the lower portion of the front component was pivotally retained against removal on a fulcrum pin carried by the crank, thus precluding complete access to the inside surfaces of both the front and rear components for cleaning. Also in production and particularly during stamping operations, slight increments in length occur in the front component due to variations in temper of the metal thus providing difficulties in assembly. The primary object is to removably mount the front component on the fulcrum pin pivotally sustaining the rear component by interrupting the offset tail portion of the front component with a slot leading to the lower edge of the tail portion and in communication with a semi-circular opening to define a fork constituted by a pair of spaced tines adapted to removably straddle the fulcrum pin received into the semi-circular opening characterizing a bearing pivotally retained on the fulcrum pin. As a further object the invention comprehends the utilization of a longitudinally shiftable pin displaceable relative to the crank to provide a relief gap between the crank and the rear component for conveniently removing the front component from the fulcrum pin or permit quick insertion of the front component in the rear component for prompt assembly.
