Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
146 words
The method for manufacture of a wire-handle swab or brush comprising 1. bending a strand of wire into an elongated shape having two legs, two U-shaped opposite ends, and two abutting but not connected strand ends located at a point between the two Ushaped ends, 2. slipping a fabric sleeve upon one of the U-shaped ends, 3. joining said abutting strand ends by welding, soldering or other means, 4. placing a plurality of substantially mutually parallel fibers or strands of yarn between and at substantially right angles to the legs and near the U-shaped end bearing the fabric sleeve, 5. mechanically grasping the U-shaped ends and twisting the wire upon itself in a single direction a plurality of times so as to form a brush or swab having a twisted wire handle with a closed loop at the end opposite the swab or brush end thereof.
Claim 2
