ABSTRACT:
A key keeper is held in a belt loop within a small closed bend thereof. The keeper has opposed small and large half loops. Straight side rods connect the loops, being tangent to both. One side rod is split to place keys on the keeper. A trough or clip fixed to a rod at the split releasably secures the rod in place. One loop is about twice the diameter of the other, the large half loop imparting resiliency to the keeper to reduce the need for expensive spring steel wire for the keeper. The keeper is made by winding a continuous wire on a mandrel wherein two end plates with pivots support a large and a small arbor. Each arbor has a cylindrical outer segment in contact with the wire. A clamping bar holds the wire in place after winding, insuring that the wire accepts the shape of the arbors. A cutter then severs the strands of wire on one side of the mandrel, separating the wound length into segments each having the configuration set forth above.
