ABSTRACT:
For a trip odometer comprising a pinion carrier and a pinion spring mounted to the pinion carrier, the improvement provided includes, on the pinion carrier, a mating surface having a thickness, two protruding locators and an underside surface, wherein each locator has a retention ramp operatively associated with the pinion spring to retain the pinion spring in a secured position. Improvement on the pinion spring comprises (a) a mounting surface, (b) a leader ramp formed at a first end of the mounting surface, (c) a second end of the mounting surface, opposite from the first end, forming acute bends and finger bends, (d) a series of leaf springs extending out of the acute bends operatively associated with the transfer gears, (e) the finger bends being interposed between the leaf springs (f) arcuate extensions protruding from the finger bends and arcing towards the mounting surface, (g) retention springs formed from the arcuate extensions, (h) bends located at the end of the retention springs, bending away from the mounting surface to form spring ramps, and (i) two locating holes defined by the mounting surface, the locators protruding through the locating holes, whereby the improvements allow self-guided one step assembly of the pinion spring to the pinion carrier.
