Abstract: A Tensioned Band Golf Putter Head comprising a continuous band of a strong flexible nature wrapped about a tensioning device which is of metallic construction and consists of a substantially rectangular block having a top, bottom, front, and rear surfaces and two rounded ends and a threaded aperture equidistant from the two rounded ends and perpendicular to the front surface adapted to mount a tensioning jack screw. The jack screw has a threaded end adapted to screw into the threaded aperture of the rectangular block and an other end adapted to mount a tensioning shoe for transferring the movement of the jack screw to the aforementioned band on the rear side of the rectangular block. The tensioning shoe is a metal block of substantially rectangular shape with it's rear surface rounded and it's front surface containing an aperture adapted to accept the jack screw at the mid-point of said tensioning shoe.

Abstract: A power receiving, torque translating, output device receives reciprocating power from a plurality of external power producers. The received reciprocating power is timed and controlled by a cam affixed inside a rotor rotating about a stationary central shaft. The central shaft is mounted inside an octagonal central block, and extends to provide rotatable mounting for the rotor. The rotor has a drum shaped portion so positioned as to overlap the entire length of the block thus placing the cam in close proximity rotation around the block. The block has rectangular grooves adapted to guide a plurality of cam following actuators during the reciprocating motion of each one. Each actuator derives motion from a connecting rod attached both to the actuator and to its respective external power producer. Each cycle of reciprocation of each actuator contains one power stroke in each direction for a total of two power strokes per cycle.
