Abstract
Adjustable axle or similar telescoping structure includes an outer frame tube of square section which telescopingly receives an inner tube having a top shim-contacting surface, two parallel side surfaces, and a lower wall of inverted V-shaped section defining two additional downwardly directed shim-contacting surfaces. Three flat plates of a polymer material are supported between the three shim-contacting surfaces and the outer frame tube. One pad is attached to the upper surface on the inside of the outer tube. The remaining two pads are connected to a wedge-shaped steel bar and are oriented upwardly by the bar to contact the two shim-contacting surfaces on the inverted V-shaped section. The bottom wall of the outer frame tube is drilled and nuts are welded onto the outer surface to receive bolts which are screwed into the nuts to contact the bottom of the bar. When the bolts are tightened, they force the inner tube upward so it contacts the upper pad. Counter bores in the bottom of the bar prevent the bar from moving while axle length is being adjusted.
