  • Patent number: 4337943
    Abstract: A guide used in teaching where to hit an object ball with a cue ball such that the object ball is deposited in a pocket of a pool table includes a marker which dispenses a small spot of a marker substance on the felt surface of the pool table. The marker substance leaves a spot on the felt which indicates the exact point at which the cue ball must be aimed in order to have the cue ball correctly strike the object ball to propel the object ball into the pocket. The marking substance is such that it will not leave a stain. The marker includes a reservoir for retaining a supply of the marking substance and an orifice which is capable of dispensing a small quantity of marking substance. The marker is supported above the surface of the felt by a support which has at least one surface capable of fitting next to the object ball and this surface is located precisely a radius distance away from the orifice on the marker.
