Manual clamping device for static balancing a wheel

A device for balancing a tire upon a wheel, said device locating upon a stand, said wheel having a hub generally centered therein and rotating about an axis generally parallel to a horizon, without marring said wheel and without the use of hand tools, comprising:

• an elongated threaded rod, said rod adapting to exceed the length of said stand;
• two conically shaped members advancing upon said rod, having lesser hardness than said hub, being of a material to prevent marring, and securing said hub and said wheel between said members;
• each of said members having an apex with a threaded hole cooperating with said rod, a surface flaring outwardly from said apex, a rim locating outwardly from said apex at the maximum diameter of said surface and being parallel to a longitudinal axis of said rod, and a base opposite said apex and outwardly from said rim, said rim and said surface being hollow, said apex being truncated, forming a flat surface generally perpendicular to said rod, said flaring surface having an outside angle from said apex to said rim, an inside angle from said rim upon an interior of said flaring surface to said apex, said inside angle and said outside angle are forty five degrees, and said apex has an approximately seven eighths of an inch outside diameter and said rim has an approximately three and three eighths of an inch outside diameter.
