Abstract: An apparatus for shelling nuts comprises adjustably opposed, manual or motor-driven, rotary wheel-type rollers that engage nuts and, as they rotate, forcibly crack the shell as the nut is transported between the rollers. The clearance between the opposed rollers is adjustable by the user to obtain an optimum cracking result. A receiving hopper is provided wherein a ready supply of nuts can be presented to the opposed rollers. The hopper design includes a chute projection that orients and directs the nuts toward the rollers where an adjustable gauge further positions the nut for optimal entry. The opposed, counter-rotating cracking rollers are grooved in a manner that provides multiple surfaces with which to contact the nut and thereby apply a plurality of forces to its perimeter. This plurality of forces is uniformly applied to produce multiple fractures in the shell.

Abstract: A portable hunting blind assembly having a collapsible umbrella roof structure supported from a central hollow cylinder and extending outwardly for terminating in a polygonal body having sides defined by the ribs of the roof structure, a handle supporting of the umbrella roof structure telescopically connected to an internal sleeve in the cylinder by means of a pivot arrangement, the handle received at its free end in a stake support structure or member having its distal end securely anchored in the ground, and an array of panel screening material sections depending from each of the polygonal sides of the roof structure and held firmly in the ground by anchor devices.
