  • Patent number: 5237893
    Abstract: A fastener drive tool for applying a rotational torque to a threaded fastener for driving the fastener into or out of a workpiece. The drive tool has an elongated shaft portion with a free end which is engageable with a recess formed in the fastener. Alternating merging concave and convex partially-cylindrical surfaces are formed on the outside of the shank towards the free end of the drive tool. The axes of curvature of the concave and convex partially-cylindrical surfaces are generally parallel to one another. The drive tool has at least one interlobular fastener retention piece attached between two convex partially-cylindrical surfaces which engage a corresponding convex partially-cylindrical surface formed in the fastener recess. The interlobular fastener retention piece releasably retains the fastener on the drive tool when the drive tool is engaged with the recess formed in the fastener and prevents wobbling of the fastener when it is driven by the drive tool.

  • Patent number: 5176050
    Abstract: A tool for the application of selected torque to the polygonal head of a bolt, to a nut or to an analogous component has a first portion which is a snug fit on the polygonal part of the component, and a polygonal second portion which can be engaged and rotated by a wrench. The material of the tool is more readily deformable than the material of the component and the material of the wrench so that the wrench deforms the second portion and/or the component deforms the first portion of the tool when the component offers a selected resistance to further rotation, i.e., in response to the application of a selected torque to the component. The first portion can be bonded or molded to the torque-receiving part of the component to be rotated, and the second portion can be coated with a film of a color different from that of the second portion to facilitate visual determination of the condition of the second portion.

  • Patent number: 5176049
    Abstract: This invention relates to hand tools in general, and more particularly to a gripping plier or wrench having compound leverage gripping power not found in the tools most commonly sold and used today. This tool further has constantly parallel jaws at any adjustment position within its capacity. When constructed as a plier, it grips the workpiece with better than a 10:1 leverage ratio which makes it practically impossible to slip without the operator releasing its grip. When constructed as a wrench for turning nuts, bolts, and fittings, its gripping power holds the workpiece so tightly that there is no possibility of rounding off the corners or otherwise damaging it during the turning operation. Additionally, if a hexagonal object has been previously damaged and has rounded off corners, the wrench version of this tool, in any of its configurations, can effectively grip and turn such an object, a feat that the most commonly used open-end, box-end, or adjustable wrenches cannot perform to any satisfactory degree.

  • Patent number: 5176563
    Abstract: A method and device for separating the legs from a carcass of slaughtered poultry in which the carcass is positioned on the rear side, legs pointing upwards, relative to the cutters, a groin incision is made between each leg and the carcass at the side of the leg facing the carcass, and each leg is dislocated at the hip joint by pressing out each leg relative to the carcass. After dislocating the hip, a caudal hip incision is made in the remaining tissue connection between each leg and the carcass, after the two parts of each dislocated hip joint are moved a certain distance apart by applying a force acting on the hip joint ball of each hip joint, pushing the hip joint ball away from the hip joint socket prior to making the hip incision, and the legs are pulled off the carcass, essentially in the lengthwise direction of the back bone and away from the tail part.
