Abstract
Abstract An apparatus for loading and trueing tires. A threaded rod supported by a pair of upstanding arms receives the tire and is rotatably driven. A floating roadbed having parallel rollers for contacting and loading the tire is forced against the tire by an expandable bag. The upstanding arms and tire are movable toward a cutting blade. A disc mounted to one end of the threaded rod receives graph paper on its outer surface, and a marking stylus is positioned over the graph paper being driven by a rod clamped to the floating roadbed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
An apparatus for changing an out-of-round tire into a round tire comprising: a tire holder receiving said tire and operable to axially rotate said tire, said tire having a tread surface; a floating roadbed movable against said tread surface of said tire; a cutter operable to remove a high portion of said tread surface while said tire is rotating under load of said floating roadbed; a first indicator connected to said roadbed indicating movement of said roadbed with said tire rotating; means connected to said roadbed and operable to radially load said tire with said roadbed as said tire is rotating; and wherein: said means is an expandable pneumatic bag; said roadbed has a frame with parallel rollers rotatably mounted thereon; said first indicator has a stylus and a circular graph, said graph is connected to said holder so as to rotate with said holder, said stylus is positioned against said graph and is removably connected to said roadbed.
