## Abstract

A manual device, for use in a stand, provides a threaded rod with two opposed cones coaxial upon the rod. The cones have wider bases located outwardly from the center of the rod and narrow tops located inwardly. Threaded holes centered in the tops of the cones admit the rod. In use, a wheel is placed upon the rod and the cones are turned towards the wheel, points toward the wheel. As the cones engage the wheel, the angled surface of each cone guides the wheel to be centered upon the rod. For open hubs, one cone is reversed so the base contacts the wheel while the top of the other enters the wheel hub and the base. When finger tight, the cones secure the wheel to the rod without marring for spinning and balancing on an axis coaxial with the rod.

## Claims

### Claim 1

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; and,
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.

### Claim 2 (depends on 1)

The tire balancing device of claim 1 further comprising:
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.

### Claim 3 (depends on 2)

The tire balancing device of claim 2 further comprising:
said apex being truncated, forming a flat surface generally perpendicular to said rod; and,
said flaring surface having an outside angle from said apex to said rim, and an inside angle from said rim upon an interior of said flaring surface to said apex.

### Claim 4 (depends on 3)

The tire balancing device of claim 3 wherein said inside angle and said outside angle are forty five degrees.

### Claim 5 (depends on 4)

The tire balancing device of claim 4 wherein 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.

### Claim 6 (depends on 2)

The tire balancing device of claim 2 further comprising:
both of said members having each of said apexes locating towards the center of said rod.

### Claim 7 (depends on 2)

The tire balancing device of claim 2 further comprising:
one of said members having said apex locating towards the center of said rod, and the other of said members having said base locating towards the center of said rod.

### Claim 8

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.
