  • Patent number: 10765092
    Abstract: A rotary high lifter and controlled descender has a main housing enclosing a ratchet spool, controlled descender, and locking pawl. An adjustable crank turns the ratchet spool and takes up rope which raises an attached feeder, nestbox, etc. The locking pawl assures that as the rope is wound, the lifter/descender automatically locks in place so that an inadvertent crank release of the crank does not cause the feeder to fall. The rope exits the main housing via an inlet nipple which protects the housing from the elements, insects, etc. To lower the feeder, actuate a cam lock to release the locking pawl, and turn the crank in the opposite direction. Releasing the cam lock can actuate a controlled descender portion of the invention. These components apply a brake-pad-like action against the ratchet spool (can also use a tension knob) to control the speed of rotation and descent.

  • Publication number: 20180360000
    Abstract: A high lift feeder protector has mounting, vertical extension, and horizontal extension members, which can be hollow to allow a suspension rope to run therethrough. The members together can resemble an extended cane. The far end of the suspension rope attaches to a feeder. The rope runs up from the feeder, into an output port on the underside of the horizontal extension member, through the horizontal extension member, through the vertical extension member, through the mounting member, and then extends out an input port at the near end thereof. The tag end of the suspension rope can then be affixed to a cleat, winch or other securing device. A rope stop can be affixed near the tag end and should be large enough that it cannot fit within the input port. Thus, the rope stop functions to stop the rope from feeding completely in and through the members.
