  • Patent number: 5321858
    Abstract: An automatic closure assembly for use with an outhouse or pit commode is disclosed which includes a frame having open upper and lower ends attached to the underside of a bench so as to frame an opening therein over which a toilet seat is hingably mounted atop the bench. The assembly also includes a pair of wedge shaped cradle members which are pivotally attached to front and rear surfaces of the frame which tilt in opposite directions from one another so as to open and close a lower end of the frame. The geometry of the cradle members is such that their centers of gravity are substantially spaced apart from their pivot points so as to provide a gravitational bias of each cradle member tending to urge it at all times toward its closed position against the other cradle member so as to seal the bottom end of the frame to inhibit odors from circulating in or about the outhouse when the assembly is not in use.

  • Patent number: 5293651
    Abstract: A toilet seat for composting toilets, which toilet seat comprises a seat ring, a bowl space, a bottom hole of the bowl space, and a separator of liquids such as washing water and urine. The toilet seat is implemented by adapting the inside surface of the front part of the bowl space to be at its upper part essentially vertical, at its middle part almost horizontal, and at its lower part convexly curved so that the center part of the curved area is closer to the rear part of the bowl space than the start and end points of the convexly shaped lower part, whereby liquids entering the front part of the bowl space in the toilet seat are conducted along the inside surface of the front part into a separate liquids collection container, or alternatively, to a treatment process, and that the liquids separator is formed by a shutter adapted to the lower part of the bowl space or below it.
