  • Patent number: 4411430
    Abstract: A golf putter of the type having a head with a front to rear elongated rod-like weight or ram encased in a transparent plastics material body is provided with a rotatable rod or ram portion to shift the axial center of mass of the head to correct manufacturing variations and to correct errors in the putting stroke. The rotatable weight or ram section has an off-center or eccentric mass which is easily adjusted from the rear face of the putter head to compensate for pulled or pushed putting strokes, thereby providing a personalized "feel" facilitating impacting the ball on a "sweet spot" which will propel it on the desired putting line.

  • Patent number: 4324404
    Abstract: A golf club putter is provided with a head having an elongated rod-like weight extending transversely of the axis of the club shaft in a front to rear direction with a ball impacting front face and toe and heel wings radiating from diametrically opposite sides of the transversely extending weight rod each with bottom faces above the bottom of the weight rod to accommodate lateral rocking of the club throughout a wide angle without rubbing against the putting surface and turning the ball impacting face as the ball is impacted. The elongated transversely extending weight rod is visible to the golfer along its length to facilitate alignment of the club head with the desired putting line. The weight delivers a desired mallet or battering ram impact to the ball without requiring a large sole area on the putter head.
