There is disclosed an elongated member having two ends and a surface therebetween over which a body may be directed, the surface containing a center line of symmetry along the length thereof and being progressively curved along the center line with a radius of curvature adjacent one end gradually increasing in magnitude to a larger radius of curvature adjacent the other end such that the curvature adjacent the other end substantially approximates the path of the body in motion which may be intercepted by the elongated member and which curvature progressively increases from the other end to the one end to smoothly deflect and change the direction of the intercepted body from the original path. A pair of rail members is attached to the surface of the elongated member, the rail members flaring progressively outwardly symmetrically about the center line from the one end to the other end to form a substantially wide flat area adjacent the other end bounded by the flared rail members such that a body which may be intercepted by the substantially wide flat area is smoothly directed along the surface between the flared rail members with a minimum number of contacts therewith as the body traverses the length of and is ejected from the elongated member. A preferred embodiment of the moving body which may be used with the elongated member is a spherical member having a spherical core, a spherical interliner surrounding the spherical core and an outer shell surrounding the spherical interliner, the spherical interliner having a low coefficient of elasticity and a minimum mass and the outer shell having a mass substantially equivalent to the mass of the spherical core and having an outer surface with a minimum coefficient of friction with respect to the surface of the elongated member whereby the spherical member may move freely over the surface of the elongated member and substantially will not bounce therefrom when intercepted thereby.

A device for intercepting and deflecting a body in motion, comprising: an elongated member having two ends and a surface therebetween over which a body may be directed, said surface containing a center line of symmetry along the length thereof and being progressively curved along said center line from a radius of curvature adjacent said one end to a larger radius of curvature adjacent said other end such that the curvature of said elongated member adjacent said other end substantially approximates the path of a body in motion which may be intercepted by said other end and progressively increases from said other end to said one end to smoothly deflect and change the direction of the intercepted body from the original path; and a pair of rail members attached to said surface of said elongated member, said pair of rail members being substantially parallel adjacent said one end and spaced apart by a distance greater than the diameter of the body which may traverse therebetween, said rail members progressively flaring outwardly from said one end to said other end to form therebetween a substantially wide flat area adjacent said other end such that a body which may be intercepted by said substantially wide flat area is deflected smoothly along said surface between said pair of rail members with a minimum number of contacts with said pair of rail memberS as the body traverses the length of said surface of said elongated member.
