Abstract: A tool, and method of utilization, for achieving fine vertical adjustment of a crop divider pivotally mounted on the front of a crop header. The tool includes an inverted J-shaped support member adapted for attachment to a frame member of the crop header. Rotatably secured to the support member is an elongated screw member to which is threadably mounted for axial movement an annular ring. The tool is mounted such that a coarse adjusting chain, which normally extends between the crop row divider and crop header, passes through the annular ring. By rotating the elongated screw, the ring moves axially in a direction generally perpendicular to the normal orientation of the chain to alter its effective length, causing the crop row divider to pivot about its mounting and thereby adjust its vertical position relative to the ground.

Abstract: Apparatus for preventing the opening of a movable closure--such as a pivoted door--from either side thereof. First and second rods are pivotedly mounted together to be folded up for storage or transport, or to be disposed in end-to-end relationship when the apparatus is operative. A third rod slides with respect to the first and second rods and operatively engages the first and second rods to lock them together in end-to-end relationship. A fork for engaging the door knob is provided at one end of the rods, and an engaging member for securely engaging either a carpet or a smooth floor is provided at the other end of the rods. A chain having an enlarged loop at one end and an elongated pin at the other end cooperates with a tubular member formed on the rods to facilitate locking of a pivoted door from the jamb side thereof.
