Abstract: A heavy duty rotary disc-type wood chipper containing a knife clamping system that conducts the impact and shearing loads acting upon the chipper knives along two primary axes which allows for more efficient dissipation of the impact loads and a reduction in the deleterious effects of off-axis loads resulting in the ability to use smaller holding bolts and smaller knives in the system without adversely effecting either the ability of the knives to stay fixed to the disc or the quality of chips produced.

Abstract: Single and double keeper fishing trot line drop hook organizers are characterized in a first preferred embodiment by an elongated shaft having a hook keeper slidably mounted on or near the top end thereof under spring tension provided by a coiled spring also mounted on the shaft, beneath and contacting the hook keeper. A clip mount is slipped on the bottom end of the shaft and is spaced-apart from the hook keeper and includes multiple clip mount openings for receiving clips attached to one end of multiple drop hook lines, each having a hook attached to the opposite end. Each hook is designed to engage the rim of the hook keeper or embed in a resilient hook medium provided in the hook keeper when the clips are connected to the clip mount, responsive to tension applied to the respective drop hook lines by operation of the coiled spring.
