Abstract
183,686. Williams, O. J. July 5, 1921. Ladders. - Step ladders have collapsable treads carried by hinge portions C which are pivoted to the sides of the ladder and also to slips D adapted to slide in grooves in the ladder sides. The slips are actuated by levers F attached to them at their top ends and pivoted to the back stay of the ladder. The Provisional Specification also states that the backs of the steps may be used for advertising matter.
