Abstract

Improvements in the construction of jacks, which comprise a first arm to which the terminal end of a second arm is pivoted, a load-bearing member applied to the opposite end of the second arm, a nut mounted so that it can pivot, on one of the two arms, and a screw threaded in the nut and mounted on the other arm, so that the screw can rotate freely to raise the second arm with respect to the first.
