Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
215 words
An apparatus to aid a person to drive a screw or to remove an embedded screw comprising: a rigid cylindrical tube which is open at both ends and which is filled with a screw holding means on the inner cylindrical wall of the tube and oriented radially towards the center of the axis of the tube; such screw holding means means including a large number of closely spaced small bristles sufficiently close together and made of flexible material stiff enough to provide numerous contact points with the screw to laterally hold it over its entire length within said tube to hold in place a driver and screw when the driver and screw are inserted into the tube for driving the screw and flexible enough to permit a driver and screw to be inserted from either end of the screw holding means; the ends of the bristles forming a cylindrical passage extending through the tube for insertion of a screw and driver and said cylindrical passage being smaller than the driver and screw to maintain a hold on the driver and screw throughout their lengths within said tube; and said bristles extending along the entire length of said tube so that the driver and screw are held laterally by the bristles during driving of the screw.
