Abstract

The apparatus is capable of being immersed in a liquid bath and supports at least two dowels or rods on which are mounted apertured discs in spaced apart relationship. Each rod has a gear fixed near one end and has a plurality of axially spaced circumferential grooves in each of which respective apertured discs are disposed. A pair of spaced wheels are provided to rotate in unison about a fixed axle. Each wheel has a plurality of radially disposed slots into which respective rods are disposed so that each dowel is capable of rotating about its own axis. The axle supports a fixed sun gear disposed near one wheel and each rod has at one end a planet gear that meshes with the sun gear whenever the respective rod is nested within a respective pair of slots on the wheels. Means are provided to rotate said pair of wheels about said axle. To prevent the rods from falling out of their respective slots as the wheels rotate, a C-shaped keeper device is disposed around each wheel and in a fixed position. The opening in the device extends upward so that each of said rods can be, in turn, mounted and removed from said wheels while the remaining rods are supported in place.
