Abstract: A manually-operated trash harvester system includes a trash retrieval assembly that consists of a rod with a spike on one end and a handle for a user's hand and an arm strap for the user's forearm at the other end and a movable tubular scraper mounted slidably over the rod and the spike. The scraper includes a flange for forcing impaled trash off the spike. The system also includes a trash collection assembly consisting of a trash bag frame mounted on wheels and includes four upstanding posts secured at the lower end thereof and movable to accommodate bags of various sizes in the interior space defined by the posts. A strap connects the bag frame to the user via a belt-like fastener to allow for hands-free movement of the collection assembly.

Abstract: A rolling apparatus to be pushed by hand to roll over ground where nuts have fallen, pick up the nuts, and collect them in a bag; the apparatus including a roller assembly of a plurality of thin wheel units each having a flexible wall member which contacts the ground and is spaced from the wall member of the next adjacent wheel unit so as to clamp nuts between adjacent walls and carry the clamped nuts around the roller assembly to a comb-like stripper which pries the nuts from the wall members and guides them into a collection bag or other collection devices.

Abstract: A lug nut attachment is provided for detecting the removal of a wheel lug nut, a device that serves as a tire security cap. The cap comprises a breakable shroud and means for mounting the cap to one lug nut of a wheel. When mounted thereto the cap encloses the lug nut and prevents access thereto until the shroud is broken.
