Abstract
Abstract A magnetic device adapted to be worn on the arm or wrist for holding magnetizable items such as nails and the like. The device includes a contractible bracelet or band of elastic, perspiration-absorbent fabric material having a magnet supported externally on it. The magnet has pole pieces with exposed, coplanar outer faces. A relatively soft collar of rubber-like cushioning material encircles the magnet. The pole faces of the magnet and the interface of the collar are substantially coplanar. A separate magnetizable keeper plate is engageable with the exposed magnet outer faces to maintain the power of the magnet while the device is out of use for extended periods.

Total Claims: 4
Claim 1
Independent Claim
115 words
In a magnetic device adapted to be worn on the arm or wrist for holding magnetizable items such as nails and the like, said device comprising in combination: a bracelet band adapted to encircle the user's arm or wrist; and a circular magnet of U-shaped cross-section supported on the bracelet band and having bare coplanar north and south poles in a plane generally parallel to the bracelet band facing outwardly to attract nails and the like and to retain them readily available to the user; the improvement comprising a relatively soft annular collar of rubberlike cushioning material encircling and coplanar with the magnet below its outer face to protect the magnet from striking external objects.
