  • Patent number: 5273285
    Abstract: A golf ball teeing mat comprising:a. a resilient horizontally disposed sheet,b. a resilient cushion, positioned under said sheet, generally continuous in the direction of hitting,c. an artificial turf affixed atop said sheet, said turf generally coextensive with said sheet, an adhesive forming a bond between said sheet and said turf, said bond having no substantial gaps,d. a concave trough formed by manual flexing of said mat, said trough having a first point where said sheet descends below horizontal and a second point where said sheet returns to horizontal, said trough having a distance between said first and second points of 8 inches or greater, said sheet being stiff enough and said cushion being soft enough to create said trough at generally any location along the upper surface of the mat sufficiently spaced from the edges thereof to permit the formation of the trough.

  • Patent number: 4010958
    Abstract: A golf putter in which mass is disposed at the corners of the club head to increase the effective hitting area of the face of the club head. The effective hitting area is not only increased in the longitudinal or horizontal direction of the face of the club head, but also in the vertical or transverse direction of the face of the club head. In addition, the density at the corners of the club head is greater than the density about the center of the mass to increase the inertia of rotation of the club head.
