IPC: F16L3/233
Filed: 2003-12-09
Abstract: A cover having first and second halves is used in combination with clamps to cover elongated items such as wires and pipes. The first and second halves cooperate together to form a cavity that receives the elongated items and clamps. The halves may be formed with identical cross sections so that they may be fabricated from a single mold. The halves may snap together or be connected with a fastener. Each cover half includes a pair of opposed locking ledges that form slots sized to receive the opposed feet of the clamp. The clamps are installed by angling the clamps with respect to the longitudinal axis of the cover and pressing the clamp against the base wall of the cover. The clamp is then twisted to a position substantially perpendicular to the longitudinal axis of the cover. The twisting motion simultaneously moves the feet of the clamp under the locking ledges of the clamp cover.

Abstract: A heavy flywheel disc having a radially spaced apart array of pockets in which are mounted knives. Short logs, which have been de-barked, are fed in with their long axis parallel to the face of the flywheel. A hydraulic ram translates the logs sideways into the plane containing the rotating knives. The use of the hydraulic ram provides for a variable infeed speed to obtain the particular thickness of shavings which provides in the end commercially desirable shavings for use, for example, in horse stables. The knives have notched cutting edges. The notches limit the width of each shaving to create strands which are for example 3/4 inches wide. The strands are then chopped in an automated chopping device such as a forage harvester to produce shavings.
