ABSTRACT:
A conveyer for delivering a column of balls to an elevated location has a rotating wheel formed of resilient material. A track has a pair of curvilinear rails which extend along a portion of the circumferential surface of the wheel and which are spaced apart by distance that is smaller than the diameter of the balls. Balls are sequentially fed onto a first portion of the track at which the rails are spaced from the wheel by a distance which causes the balls to be pressed against the wheel. The edges become closer to the wheel at a second portion of the track causing increased clamping pressure against the balls at that portion of the track. A ball delivery tube extends upward from the outlet end of the track. The increased clamping pressure against balls which are momentarily below the base of the upwardly extending column of balls enables elevation of a column of balls to a greater height.
