Abstract: The stick removal mechanism for nut harvesting includes a frame having opposing side members and sprockets mounted on the side members. A roller chain is mounted on the sprockets on each side of the frame. A plurality of cross members having fingers extending therefrom is attached to and extends between the roller chains for travel therewith. A plurality of cross members and their chains define an endless conveyor belt. An adjustable agitator mechanism is installed upon each of the side members, which adjusts corresponding agitator sprockets to lift and agitate the respective roller chains. The stick removal mechanism is installed over the open top of a collector receptacle, e.g., a cart, so that debris is carried atop the conveyor and dropped behind the cart while nuts fall through the passages between the fingers and into the receptacle.

Abstract: The hand truck brake provides automatic braking for a hand truck as it negotiates a stairway or other uneven surface. The brake is adaptable to various types of hand trucks, including powered stair-climbing trucks. The brake includes two major assemblies. The first is a reciprocating plunger having a distal roller that travels along the surface. When the roller travels over the nose of a stairway tread, the plunger extends to actuate the brake. The second major assembly is a rotary cam rotated by the plunger as it extends. The cam has an extension and a brake shoe, the brake shoe engaging the underlying surface to stop the hand truck when the cam is rotated to its brake-engaging position. The assembly automatically retracts when the hand truck is oriented vertically. Additional controls are provided for the operator to extend or retract the brake mechanism.

Abstract: The modular dolly is a manually operated device facilitating the transport of large, heavy, and/or bulky objects. The dolly includes four smaller wheels and two larger diameter wheel and brake assemblies for temporary installation to the sides of the dolly platform for movement over soft, rough, and/or uneven surfaces. A ramp is removably attachable to the loading end of the platform coplanar therewith to facilitate loading the dolly. The ramp also attaches removably to the opposite anchor end of the platform and normal thereto, to serve as a backstop or anchor for a load placed on the platform. A smaller secondary panel may be installed in the anchor end when the ramp is in use during loading, or may be assembled coplanar to the ramp or platform to lengthen the ramp or platform. The dolly may also be used with a stair-climbing hand truck, forklift, pallet jack, or the like.
