The claims defining the invention are as follows:
1. An improved clearer board for a beehive, said board including at least two sheets each having a plurality of apertures therein, said sheets being adapted, in use, to be in juxtaposition between two enclosures for bees or the like, said sheets being relatively and progressively movable between two end or limiting operating positions, a first end position wherein said apertures on the respective sheets are in substantial alignment and a second end position wherein said apertures are out of alignment, whereby to allow for control of the passage of bees between said enclosures.
2. The clearer board as claimed in claim 1, having at least one escape for bees associated therewith.
3. The clearer board as claimed in claim 2, wherein the size of openings provided to the or each escape for bees is adjustable whereby to allow for selective screening of drones, queen bees and/or worker bees, or to block access to said escape altogether.
4. The board as claimed in claim 2 or claim 3, having at least 2 distinct operating positions or conditions, a first position allowing worker bees to pass freely through said apertures, and a second position wherein all said apertures are substantially closed such that worker bees have access only through the or each bee escape.
5. The board as claimed in claim 4, wherein said apertures are of a size sufficient to allow for passage of a queen bee therethrough, and including a third, operating condition or position wherein a queen bee can pass through said apertures.
6. The board as claimed in any one of claims 1 to 5 wherein, when said apertures on said sheets are in substantial alignment, said board allows for passage of a queen bee from said hive, wherein when said apertures are in an intermediate, partially aligned configuration said board acts as a queen-excluder, and wherein when said apertures are out of alignment said board acts as a clearer board for assisting harvesting of honey from the hive.
7. The board as claimed in any one of claims 1 to 6, adapted for location within a beehive, including respective upper and lower sheets adapted for location within a frame, wherein said lower sheet is fixed within said frame and said upper sheet is relatively movable therein.
8. The board as claimed in any one of claims 1 to 6, adapted for location within a beehive, including respective upper, middle and lower sheets' adapted for location within a frame, wherein said upper and lower sheets are fixed within said frame and said middle sheet is relatively movable therebetween.
9. The board as claimed in any one of claims 1 to 8, wherein said apertures are of substantially the same dimensions and are disposed in a uniform array on and throughout said sheets.
10. The board as claimed in any one of the preceding claims, including at least one tab, handle or the like means projecting from one side of at least one of said sheets whereby to allow for relative movement of said sheets in response to the application of force to the or each said tab, handle or the like means.
11. An improved clearer board for a beehive, substantially as described herein with reference to the accompanying drawings .

12. A method of assisting in the handling of bees, using a clearer board as claimed in any one of the preceding claims.

AMENDED CLAIMS
[received by the International Bureau on 02 June 1986 (02.06.86);
original claim 1 amended; other claims unchanged (1 page)]
The claims defining the invention are as follows:
1. An improved clearer board for a beehive, said
board including at least two sheets each having a
plurality of apertures therein, said sheets being
adapted, in use, to be in juxtaposition between
the super and the brood chamber, said sheets being
relatively and progressively movable between two end or limiting operating positions, a first end position wherein said apertures on the respective sheets are
in substantial alignment and a second end position , wherein said .apertures are out of alignment, whereby to allow for control of the passage, of bees between
said enclosures.
2. The clearer board as claimed in claim 1, having at least one escape for bees associated therewith.
3. The clearer board as claimed in claim 2, wherein the size of openings provided to the or each escape for bees is adjustable .whereby to allow for selective screening of drones, queen bees and/or worker bees, or to block access to said escape altogether.
4. The board as claimed in claim 2 or claim 3,
having at least 2 distinct operating positions or
conditions, a first position allowing worker bees to pass freely through said apertures, and a second
position wherein all said apertures are substantially closed such that worker bees have access only through the or each bee escape.
5. The board as claimed in claim 4, wherein said apertures are of a size sufficient to allow for passage of a queen bee therethrough, and including a third
operating condition or position wherein a queen bee
can pass through said apertures.
6. The board as, claimed in any one of claims 1 to
5 wherein, when said apertures on said sheets are in substantial alignment, said board allows for passage
