Abstract: One piece spray structures can be constructed so as to include a body shaped so as to hold a slotted nipple which directed toward a deflecting surface in the body. The body is preferably integral with a stake capable of supporting the body and the nipple in such a manner that when a tube is located on the nipple water will pass form the tube against the deflecting surface and be deflected outwardly away from the body. Diverging side walls are located along the deflecting surface so as to define a control slot through which the water has to pass in combination with the end of the tube on the nipple and the deflecting surface. If desired walls may be located so as to overhand the cavity generally above the defecting surface. Several nipples may be located on the body. When this is done preferably each nipple is used so as to distribute water differently than the other nipple on the body.

Abstract: An improved can crusher has two movable jaws, a first jaw and a second jaw, both movably mounted in a support housing. The jaws are initially spaced apart one from the other a distance sufficient to allow a can to be inserted between them. A member capable of generating a mechanical force is mounted on the housing and is directly connected by a connecting member to the second of the movable jaws by a force transferring member and is indirectly connected by the same connecting member to the first jaw by a force modifying member. The force modifying member modifies the mechanical force so generated to achieve a mechanical advantage. When the member capable of generating the mechanical force is activated this force is first transferred to the first jaw, and because of the mechanical advantage achieved, the first jaw is able to initially overcome the structural resistance of the can and crimp it.
