Abstract:
An archery bow draw board for an anchored compound archery bow having a riser, limbs, at least one cam with a pulley, or two cams, a bow string with a cable. The draw board is connectable to the bow string and includes a base plate supporting a gallows vertical pole and a gear box and side plate fixed therebelow. A worm drive on a shaft is mounted within the gear box and is turnable by an outwardly extending crank handle. An axel with a fixed reel and worm gear extends from the side plate into the gear housing wherein the worm gear meshes with the worm drive to drive the reel in either direction by turning the crank. The worm drive and worm gear hold the reel in place upon releasing the crank. A gallows horizontal extension is located on top of the gallows pole with a first pulley, and a second pulley in line with and spaced from the first pulley away from the gallows pole. A cord is wrapped around the reel and extending upwardly along the pole to the horizontal extension and over the pulleys and then downwardly adapted to hook onto and pull the draw string. Numeric indicia is fixed on the gallows pole and a bow draw length marker coordinated on the cord indicates draw length of bow string pulled by the draw board. A scale maybe placed between the cord and the bow string to indicate actual draw poundage as the bow string is pulled.
