Description

RARE Dark Black Automobile Mechanic Swivel Jack- Pat No.- 3862743- Condition is Used. Shipped with USPS Priority Mail.
Abstract
A screw jack is disclosed which has a side load member for engaging vehicle suspension parts or other loads at relatively low elevations. The side load member is provided with a bumper and a displaced hook for engaging the load from opposite sides and producing a force couple. The force couple minimizes bending stresses on the jack, thus contributing to jack safety and long service life. A second load engagement point is provided atop the jack for engaging loads at relatively high elevations. If desired, a spring can be interposed between the side load member and the jack body to urge the side load member into an opened position for readily engaging the load. The side load member is attached to the screw member so as to permit the side load member to be tilted, by the spring, into its open position.
