  • Patent number: 4409697
    Abstract: A rack for a beehive for handling a brood chamber and a honey chamber. The rack includes a frame carrying the brood chamber below a queen excluder and the honey chamber above the queen excluder. The queen excluder is mounted on the frame to support the honey chamber, and the brood chamber is supported on a moveable portion of the frame which, in normal position, locates the top of the brood chamber against the queen excluder. The movable member is lowerable to release the brood chamber in order to permit its withdrawal from the frame for inspection purposes. In the preferred embodiment of the invention, the frame also includes a closure member to close the bee access aperture leading toward the brood chamber when the movable frame member is lowered.
