Abstract

639,039. Holding and picking-up tools; spanners; screwdrivers. GARDNER, A. C. July 8, 1948, No. 18358. [Class 61 (ii) and 61 (iii)] [Also in Group XXXV] A magnetic device for holding and picking up articles comprises a permanent magnet a having one end attached to a surrounding shroud b of highly permeable metal, the space between the two members containing non-magnetic material d. The device is adapted for use in confined spaces by aligning the ends c of the shroud and the end of the magnet and providing a flexible handle e. In modifications, the end of the shroud projects beyond the magnet and is shaped as a box spanner, or is shaped to fit into a standard box spanner and form the handle thereof. In another modification, the shroud is bridged by a bar of non-magnetic material serving as a screwdriver bit.
