  • Patent number: 5628610
    Abstract: A lifting apparatus preferably for applications in which a floor covering is to be removed and/or installed, has a lever arm and support that provide portions of two interconnected linkages. An interchangeable bracket is raised and lowered by the lifting apparatus. The bracket is provided with single-sided and double-sided portions that insert into a partition member to raise the partition when the bracket is raised by the lifting apparatus. A rachet arm is provided by a spring-biased stop member and a serrated portion. The rachet allows the lifting assembly to support the weight of the partition without constant attention, thereby allowing the workers to perform either the removal or installation of a floor covering without an inordinate amount of partition movement.
