Abstract: Disclosed is a device for cleaning paint roller covers. At the end of a painting operation, the operator removes one or more paint roller cover, places them onto a shaft and drops into open slots on the ends of the enclosure. A pressurized fluid hose is attached and allows the fluid to penetrate the entire length of the roller covers. The fluid can be adjusted to direction of the flow to the axis of the roller covers may be used to control the rate of spin and penetration of the fluid into the cover. The adjustment can also be used to optimally direct the fluid flow for smaller trim roller covers to very thick diameter roller covers. The operator may then leave the device operating unattended while it washes and cleans all the paint from the outside surface of the roller covers.

Abstract: An oscillating sorting conveyor is adapted for separating whole berries of wine grapes from undesirable components such as “shot berries” (immature grapes), stems, raisins, leaf material, bugs, pebbles and the like. The sorter deploys a downward tilting trough that is driven to oscillate. A screen is disposed at the bottom of the trough such that whole berries are conveyed over the screen while the undesirable components pass through the screen The preferred embodiment of the screen has a non-uniform cross-section to improve the efficiency of removal the undesirable components without clogging or requiring constant maintenance.

The sorter deploys a downward tilting trough that is driven to oscillate. A screen is disposed at the bottom of the trough such that whole berries are conveyed over the screen while the undesirable components pass through the screen. The preferred embodiment of the screen has a non-uniform cross-section to improve the efficiency of removal the undesirable components without clogging or requiring constant maintenance. The preferred embodiment of the oscillating conveyor is driven by a cam and cam follower, in which the cam driving shaft is counterweighted to minimize vibration. The more preferred embodiments minimize damage to the grape berries while efficiently removing the undesirable components.
