 without first making a seat, and then bridging the area between adjacent bit blocks with gussets to strengthen the arrangement. In either construction, knock-out holes are generally provided to facilitate removal of a used bit.
These prior art constructions result in cutting drums having very jagged surfaces because the bit blocks and gussets create numerous irregular and uneven surfaces. Falling pieces of coal that have been cut from the coal seam by the cutting bits crash into these jagged and irregular surfaces on the rotating drum. This creates particles of coal and coal dust and distributes them throughout the region surrounding the cutting drum. Such is very dangerous to those working in the mines and reduces the efficiency of the entire longwall mining operation. Light fixtures, or luminaires, are used with electric light sources to provide an aesthetic and functional housing in both interior and exterior applications. One type of light fixture is an area light, generally used for exterior lighting of roads, walkways, parks, parking lots, or other large areas requiring a significant amount of lighting. Area lights typically include a light fixture attached to a pole, wall, or other elevated structure to provide an elevated lighting position. In recent years, lighting applications, including area lights have trended towards the use of light emitting diodes (LEDs) as a light source in place of conventional incandescent and fluorescent lamps. 1. Field of the Invention
The present invention relates to improvements in devices for recreational or body-support floatation in water using a flexible foam tube or tubes and a fabric or mesh sling.
2. Description of the Prior Art
Body support of an individual in the water for the purposes of recreational floatation or body-support may currently be accomplished by a number of different means.
The use of recreational floatation devices is widespread. Most popular are a very large number of inflatable products composed of flexible air-impermeable material such as vinyl plastic. The water mattress as described in U.S. Pat. Nos. 2,068,134, 2,939,158 and 3,068,494 are common examples. These inflatable air mattress products may be simple and inexpensive or elaborate and expensive. Inflatable products are distributed in many shapes based such as, for example, dinosaurs, lobsters, whales and many others. Adaptations may provide for example, leg holes, handle grips, drinking glass holders and clear plastic viewing windows to look through into the water under the inflatable.
