Years ago I remember my mom calling these hublifters. Well Mom is gone now and whatever grandma told her is gone too. Mom said granny carried these in the trunk of her 31 Chrysler coupe. Maybe someone here can identify them. They are made by J. C. Moore & C0. Racine Wis. Patent date Jan 14 , 1908 They are adjustable and look like you should be able to lift all four wheels off the ground. Any info is appreciated.
