Abstract

980,087. Lifting jacks. METALLIFACTURE Ltd. May 12, 1961 [May 24, 1960; Jan. 24, 1961], Nos. 18199/60 and 2745/61. Heading B8J. In a jack for lifting road vehicles a nut carrying a load engaging member (not shown) is threadedly engaged on a lead screw 9 to which a pinion 10 is secured and rotated by rotation of a worm 8 mounted on a shaft 3 disposed to one side of the lead-screw 9 and at an angle to the horizontal (assuming the pinion 10 is rotated about a vertical axis). Rotation of the leadscrew 9 raises or lowers the nut and hence the vehicle. A thrust bearing 7 and a wedged bearing member block 4 are nylon.
