Abstract: A portable telescoping observation stand attachable to a pole, a tree or like object by way of straps includes a plurality of telescopically engaged sections maintained in an extended position by locking members removably received in slots in overlapping ends of adjacent sections. Foot hold members removably attached to the sections provide steps for the stand with the locking members also serving as steps for the stand. When the stand is collapsed, the sections are nested together, the removed locking members and foot hold members are stored in a compartment defined by the nested sections.

Abstract: A conveyor carries cans or other refuse from a source of cans to a jaw crusher. The conveyor is adapted to drop cans generally one at a time into a bin, and the bin has an opening to release each can when the jaws open to receive it. In the open position, the jaws are spread far enough apart so that the can drops to the bottom thereof. A flap is provided at the bottom to hold the can between the jaws. The end of the flap extends to a position above the bottom of the stationary jaw. As the jaws come together in crushing, the moving jaw cams the flap downward along the stationary jaw. However, the flap is not cammed entirely out of the area beneath the jaw until the jaws have come together to hold the can. The flap ensures that no lip is formed on the can. After the jaws close, the flap is moved out from beneath the jaws so that when the jaws open, the crushed object can fall out of the jaws for carrying away.
