Abstract
A magnetic lifting tool is set forth for use in cleanup and removal of ferrous metals from construction sites, such as nails and the like. A circular lifting plate includes a plastic housing with an included steel pickup surface which has secured thereto a multi-adjustable handle for accommodating various statures of users of the tool. A permanent or electromagnet insert is positioned between the pickup surface and housing for providing magentic lifting force. The circular housing eases manipulation of the tool about a construction site surface.
Claims5
A magnetic lifting tool for use in removing ferrous debris, said tool comprising:
- an "L" shaped handle including an elongate hollow vertical leg and a hollow vertical leg and a horizontal leg of lesser extent than said vertical leg, and
- a hollow securement sleeve slidably secured to said handle along a first extent portion of said sleeve and fixedly secured to housing means along a second extent portion of said sleeve, said first and second extent portions of said sleeve spaced at opposite ends of said sleeve, and
- said housing means including a cylindrical housing of a first diameter and socket of a second diameter directed upwardly of said housing means accepting said securement sleeve, and
- a magnetic means for magnetically attracting ferrous debris secured within said housing means, and
- wherein said horizontal leg includes a frictional grip encompassing a majority of a surface defined by said horizontal leg, and
- wherein said securement sleeve is formed with a series of axially spaced openings cooperative with a resilient detent secured within said vertical leg and projecting through an opening in said vertical leg to cooperative with one of said spaced openings, and
- wherein said socket is of a diameter to accept said securement sleeve therein including a plurality of fasteners to secure said securement sleeve with said socket, and
- wherein said first diameter is six inches and said housing means of a height of one inch to define a six to one ratio of said first diameter to said height, and
- wherein said housing means includes a working surface formed of a magnetically attractive metal,
- and said surface formed along and defining a lowermost face of said housing, and
- an upper surface and sides of said housing means formed of plastic-like material.
