2008.1.1: This device was created by Richard Bowden when he was in high school ( he lived on the Bowden Farm then at Goodale's Corner in Orrington, ME). The bottom appendages would be fitted onto a gear or pulley from a shaft. The center bolt at the top, which is missing, would be turned into the center of the round shaft, with the appendages grasping the back side of the pulley. "When the center bolt is tightened against the center of the shaft, it pulls the pulley or gear from the shaft," according to its maker. "Visualize a belt pulley on the front of an engine that drives the alternator, air conditioner compressor, power steering...etc....the pulley needs to be removed from the shaft in order to replace the oil seal that has developed a leak..." Such a hand-made device embodies Maine's propensity for solving problems with both ingenuity and the materials at hand. From the Farm of Donald and Thelma Bowden, Goodale's Corner, Orrington, ME., steel, c.1956.
