Shock Absorber Testing Machine - Portable Design With Indicator Wheel, Horizontal Displacement Functionality For Accurate Measurements

A machine for testing automobile shock absorbers which includes a portable structure having an indicator wheel that may be pressed against a fender or other suitable place at the side of an automobile. Rotation of the wheel as the adjacent part of the automobile is depressed, then released operates, through a drive connection, a stylus which marks the movement on a traveling sheet of paper. The indicator wheel is mounted on a yieldable arm permitting horizontal displacement, and the drive connection between the indicator wheel and its stylus is so arranged that such horizontal displacement does not cause the wheel to turn so that the surface engaged by the wheel may slope substantially yet have no effect on the stylus movement.
