Abstract: A honing tool comprises an hexagonally shaped mandrel having a cylindrical bore extending centrally therethrough. Six similar tool holders are each provided with a pair of spaced cylindrical gear racks having rack gear teeth formed thereon and integrally attached to an elongate tool support. A metal tool carrier to which is suitably bonded a tool, such as an abrasive cutting stone or a wiper is removably attached to a respective tool support by a clamp screw. The gear racks of each tool holder are slidably mounted in respective bearings holes in the mandrel. Gear teeth on the racks mesh with gear teeth formed on a splined shaft rotatably mounted in the mandrel bore. Thus, rotation of the shaft counterclockwise relative to the mandrel extend all of the tools outwardly to extended positions.

Abstract: Inclined chutes are filled with game balls of different colors or other visual characteristics. The underlying wall of each chute is formed of elastomeric material with openings therein of smaller diameters than the diameters of the balls so that the balls may roll down the chute and rest against each other and against a stop under the influence of gravity. Depressible plungers aligned with the openings may be selectively depressed to displace underlying balls through the openings from which they are guided to a display station.
