Spatial Analysis of Annual Air Pollution and Mortality

A wire stripper having flat arcuately shaped blades pivotally mounted upon one end of a rotor rotatably mounted on a frame, with their axes of pivot being parallel and spaced relative to the axis of rotation of the rotor and located to cause centrifugal force to urge them to noncutting position. A shiftable sleeve telescopically carried by the rotor bears a cam which moves the blades to cutting position on opposite sides of the axis of the rotor along which the wire is presented by a pair of substantially parallel horizontal clamping arms. These arms are mounted for pivotal movement on the frame about a pair of spaced vertical axes of pivot and have terminal wire gripping portions which are alternately received in a wire-length gauge and an opening in the frame which is entered at the axis of the rotor, to present the desired length of wire to the cutting blades at the very axis of the rotor.
