Abstract:
A combination tool for measuring the bolt patterns of wheel rims and axles comprising:a first circular plate having three slots arranged from proximate its outside edge to incline towards its center, wherein two slots are positioned head to tail, said first plate having a scale indicia on a portion of the edge;a second circular plate of larger diameter having three slots arranged in a pattern of two slots positioned head to toe, wherein all three slots incline toward the center in a direction opposite to that of the three slots in the upper plate, and each corresponding slot of each plate intersect;said second circular plate having a single indicia mark on an edge which aligns within said scale indicia on the upper plate for a predetermined circular bolt pattern size;a peg having a circular notch in a central portion and positioned vertically and slidably in each of the three intersecting points of both first and second plates, whereby the first and second plates are held snugly together and rotate in opposite directions;each peg portion extending from the first plate having a countersunk end, whereby said countersunk end can be placed on a axle bolt;each peg portion extending from the second plate having a tapered end, whereby said tapered end can be placed in a bolt hole of a wheel rim; anda first knob attached to the first plate, intersecting the bottom plate, and integral with a second knob, which permits rotation of the second plate; wherebya user can measure the wheel axle bolt pattern with the first plate and scale exposed, and reverse the device to measure the wheel rim bolt pattern for proper alignment and diagnosis with the second plate exposed.
