摘要： A boring tool for radial widening or enlargement of a cylindrical bottom, foundation, or anchor bore. The boring tool comprises a tubular tool body having a tool shank provided for clamping in a driving machine or prime mover, and an enlarging spindle guided in the tool body and adapted to be supported on the bottom of the bore. When entering into the tool body, the enlarging spindle radially adjusts the cutting parts or elements provided for carrying out the enlargement. The tool body is formed of radially resilient segments which extend in the axial direction and delimit longitudinal slots which are open toward the front end of the tool. Cutting parts or elements are arranged on the free ends of the segments, with each part having an axial working which extends in the circumferential direction of the tool body, with those working surfaces which are adjacent one another in the circumferential direction forming the front end face of the tool body. In the starting state of the tool body, the cutting parts form a substantially complete circular ring.

摘要： A coupling hook assembly having a hook body defining an enclosed hook pocket with a locking bolt extending from a first aperture in the hook body into operative engagement with a hook jaw to lock and unlock an implement pin for joining a trailer with an agricultural tractor. The locking bolt is pivotally connected with an operating lever mounted on a fixed pivot within the hook body and extending through a second aperture therein. A yoke pivotally mounted on the operating lever is adapted to engage with a notch formed on the external surface of the hook body to secure the locking bolt in the locked position or into engagement with a recess in a part of the operating lever to secure the coupling hook assembly in the unlocked position.
