Abstract:
1. A device for agitating a canister of material having a bottom wall with a concave surface and a longitudinally extending center axis extending therethrough and allowing mixing of the material within the canister by use of a rotary tool comprising: a housing having a main axis extending in a first direction and having a guide to position said center axis of the canister coincident with said main axis of said housing and for removably holding the canister of material for movement both longitudinally in said first direction and rotation about said main axis, said housing including a first end portion and an opposite second end portion; a stem having a stem axis of rotation and being rotatably mounted to said housing and located at said first end portion, said stem having a stem end to drivingly receive a rotary drill for rotation of said stem about said stem axis of rotation; a spherical ball in contact with said concave surface of said canister, said spherical ball mounted on said stem and having a center with said spherical ball located at said first end portion and offset relative to said main axis so the spherical ball engages said concave surface of said canister, said center of said spherical ball positioned offset relative to said stem axis of rotation to engage said canister and reciprocally move said canister along said main axis in said first direction while simultaneously rotating said canister around said main axis; and, a spring mounted to said housing operable to urge said canister into engagement with said spherical ball but yieldable to allow said canister to be disengaged from said spherical ball and removed from the housing.
