Abstract: A butterfly type sponge mop includes a self-contained wringing mechanism comprising only two molded parts, an actuating lever and an enclosed yoke. A pair of hinged wings can be integrally molded onto one end of the actuating lever, and the lever can rotate back and forth within the enclosed yoke. Guides within the yoke can swing the wings closed when the lever is moved forward, squeezing a detachable sponge. The mechanical advantage of the actuating lever can increase as it is moved forward. Moving the lever back to its original position can cause the wings to swing back open, aided by the compression of the sponge.

Abstract: An improved dustpan includes an elongated receptacle with a lip at one edge of the perimeter of the receptacle and a handle or grip attached to the opposite edge. The handle extends away from the perimeter edge of the receptacle opening in a direction perpendicular to the lip and is unsupported at its far end. The elongated receptacle extends beneath the handle at least as far as the end of the handle, and can extend further. The elongated receptacle has a flat end wall that permits the dustpan to be stored upright without emptying or spilling its contents. In its upright storage position the dustpan lip is upward and the handle is downward. The end of the handle can stabilize the dustpan in its upright storage position. Several of the dustpans can be nested.
