LEG LEVELING DEVICE Inventor: Gerard J. Berkowitz ABSTRACT OF THE INVENTION DISCLOSURE In a preferred embodiment of the present invention, there is provided a leveling device for semi-automatically leveling and locking a plurality of legs of a legged unit such as a washing machine, a stepped ladder, or the like. In this most preferred embodiment, each leg spring biased in a down- ward direction is clamped by a cylindrical sleeve of which half of the cylindrical wall thereof is pivoted on the other half, and is pressible such that the large surface of the sleeve is frictionally engaged with the leg in the locked state thereby providing secure frictional binding of the leg against further axial movement because of weight and/or vibrations of the articles such as a washing machine, and in conjunction with such clamping mechanism of a sleeve, there is provided a lever which includes in and as a part of the lever flanged male and female mated sections thereof biased apart by a strong spring such that upon withdrawal of the lever the pressure on the clamping mechanism of the sleeve is relieved but upon pressing forward of the lever, a firm and constant pressure is exerted against the pivoted clamping wall by virtue of the spring of the lever, the spring of the lever making it unimportant for the lever to be of any exact length, this being particularly important in view of the presence of a common pressure applying and pressure releasing lever for each of a plurality of the levers leading to different legs, in such a situation the actual length of these leg levers being slightly different from one another when connected to the central pressure applying and pressure releasing latching lever.
