A first plurality of four laminated knob end pieces are secured adhesively in circumferential and interconnecting fashion to associated planar faces of the elongate member proximate the first knob end. A second plurality of laminate and elongate extending barrel pieces are secured adhesively in likewise circumferential and interconnecting fashion to the associated planar faces of the elongate member and at a spaced distance from the first knob end and terminating proximate the second barrel end.

  • Patent number: 6050910
    Abstract: A baseball bat turned from a single piece of maple wood and including an elongate and substantially circular cross sectional shaped body with a handle portion terminating at a first end in an integral knob, an outwardly tapered and intermediate portion extending from the handle portion, and a barrel portion defining a ball hitting portion and extending from the intermediate portion so as to terminate at a second end. The second end of the barrel portion establishes in cross section a substantially cylindrical shaped and recessed cavity, the cavity being defined by an annular inner wall and a substantially flat end wall. A cross sectional end face of the integral knob further being defined by a concave surface which establishes a further recess cavity. The maple construction further provides a bat which is equivalent in weight to ash while narrower in barrel diameter, longer in effective hitting length and, as a result of its narrower diameter, is faster in swinging velocity.
