Abstract: A clamp is configured for use with a coil handler device for grasping, lifting and transporting a coil of material, the material coiled in such a manner as to have an outer periphery and an inner periphery. The handler device includes a frame and a lifting assembly. The clamp includes a body, and first and second clamping surfaces for engaging and securing the coil along a radial line at the inner and outer peripheries of the coil. A first clamp leg is elongated in a direction along the radial line. A second clamp leg is fixedly connected to the first clamp leg, transverse to the first clamp leg at a first end. The second clamp leg has a second end operably connected to the lifting assembly for raising and lowering the coil secured by the clamping element. First and second clamp arms are positioned along the first clamp leg for securing the coil at the inner and outer peripheries.

Abstract: A coil handler device is configured for grasping, lifting and transporting a coil of material that is coiled in such a manner as to have an outer periphery and an inner periphery and to define a longitudinal axis. The handler device includes a frame and a grasping and lifting assembly. The grasping and lifting assembly includes at least one clamping clement having first and second clamping surfaces for engaging and securing the coil along a radial line at the inner and outer peripheries of the coil. The clamping element includes a first clamp leg elongated in a direction along the radial line and a second clamp leg fixedly connected to the first clamp leg transverse to the first clamp leg at a first end. The second clamp leg has a second end operably connected to a lifting assembly for raising and lowering the coil when it is secured by the clamping element.

Abstract: A hand held gun-type air injection device is provided for rapidly filling an inflatable dunnage bag with entrained ambient air to a predetermined maximum stabilized pressure level. The injection device is adapted for use specifically with a dunnage bag having a housing defining a chamber extending from an opening on the exterior of the bag to an opening in the interior of the bag. A tube assembly is provided for supplying pressurized gas or air adjacent the housing on the dunnage bag. A ring-like alignment frame is provided on one end of the tube for locating the tubing relative to the housing and in alignment with the chamber in the housing. The alignment frame is substantially open or apertured to permit free flow of ambient air past exterior portions of the tube into the chamber. One or more orifices are located on a portion of the tube to allow discharge of jets of high pressure gas or air therethrough.

Abstract: A hollow housing is mounted in a wall of the dunnage bag and defines a chamber having an exterior opening in a portion of the housing on the exterior of the bag, and an interior opening in a portion of the housing communicating with the interior of the bag. A tube is provided for supplying pressurized gas or air adjacent the housing on the dunnage bag and has an alignment frame on one end for locating the tube relative to the housing and in alignment with the chamber in the housing. The alignment frame is substantially open to permit free flow of ambient air past exterior portions of the tube into the chamber. One or more orifices are located on a portion of the tube to allow discharge of jets of high pressure gas or air therethrough.

Abstract: A method is disclosed for rapidly filling an inflatable dunnage bag with entrained ambient air to a predetermined maximum stabilized pressure level. A dunnage bag is provided with a housing defining a chamber extending from an opening on the exterior of the bag to an opening in the interior of the bag. In the preferred form of the method, a supply of pressurized gas or air is brought adjacent to the housing in the dunnage bag and is located relative to the housing and in alignment with the chamber to permit flow of ambient air into the chamber. One or more jets of high pressure gas or air are discharged into the chamber substantially parallel to, and spaced from, the walls of the chamber, whereby, ambient air is entrained through the chamber to the interior of the bag until an equilibrium is reached where the mass flow rate of the air entering the bag equals the mass flow rate of the air flowing back out of the bag in response to the internal pressure.
