7/962867

Jack L. Johnston - Bradenton FL

Abstract:
A multi-jointed support arm accepting various Ophthalmic instruments and platforms is suspended by cables distributing the weight of said arm and instruments up and over two sets of pulleys and back down to a counterweight.

An outer shroud conceals mechanical components of this device prior to the support arm.
