  • the device shown includes a cabinet having an upper portion, generally designated 102, and a lower portion, generally designated 104, with a back portion, generally designated 106, contiguous with the lower portion 104.
  • a toilet seat 108 is mounted on the top wall 107 of the upper cabinet portion 102.
  • the toilet seat has a central opening 109 in registry with an opening 110 through the top wall 107 of the cabinet upper portion 102.
  • a lid or cover 111 is mounted above seat 108 by a suitable hinge, generally designated 112, in the normal manner of mounting a toilet cover.
  • An interior cone-like tapered wall 113 is secured at its upper end to the upper cabinet wall 107 at a position surrounding the cabinet wall opening 110 and extends downwardly to define a receptacle.
  • the tapered wall 113 terminates at its lower end immediately above a slide valve member 114 which defines the bottom wall of the receptacle.
  • Slide valve member 114 is mounted in the lower cabinet portion 104 by suitable slide pins 116 which are received in lateral slide tracks 118 so that the valve member 114 can be slid from its position shown in full lines in FIG. 1 to a rearward inclined position shown in tails of such operations in similar systems, see Frankel US. Pat. No. 3,338,191 and copending Frankel US. Pat. application, Ser. No. l08,050, filed Jan. 20, 'l97l.
  • a disposable cup 120 such as paper liner, may be positioned on top of slide member 114 before use of the device. After use of the device and the slide member 114 is moved rearward by closing the toilet lid, the liner drops into a lower combustion chamber, described hereinafter. It will be noted that the forward edge of the slide member, when in closed position, is disposed under a flange 122 having an upwardly extending lip or dam 124. Dam 124 surrounds the front lower edge of the tapered wall 113 to direct any leakage of liquid downward into the clearance between valve member 114 and flange 122 so that such liquid is delivered into the combustion chamber even when valve member 1 14 is in closed position.
  • combustion pot 126 which defines the aforesaid combustion chamber.
  • Combustion pot 126 is preferably made of a heat resistant material such as a porous ceramic insulation material which will resist temperatures in the order of 2,500 F. The porous material absorbs liquids on the porous surfaces and thereby exposes a greater area of liquid to the heat and flame within the combustion chamber, resulting in faster vaporization.
  • a burner 128 is mounted at a suitable rearwardly inclined angle to deliver a flame into combustion pot 126 for burning purposes.
  • the combustion pot should be sufficiently large to act as a storage chamber to accumulate waste from a plurality of uses of the device before burning is initiated.
  • splash rings or baffles 130 and 132 are provided in the combustion pot to prevent liquified materials from splashing out of the pot or onto the burner 128 whereby the flame might become extinguished.
  • Other suitable projections can be provided on the bottom wall of the combustion pot to serve the same purpose.
  • the burner 128 is supplied with fuel, such as liquified propane, through a gas line 134 which is controlled by a suitable valve, such as a solenoid valve 136 (FIG. 2).
  • a suitable valve such as a solenoid valve 136 (FIG. 2).
  • Control of a solenoid type gas line valve, in a suitable timed cycle is disclosed in Frankel et al. US. Pat. No. 3,304,559 and is incorporated by reference herein.
  • Said patent shows a timer which provides a first timed burning cycle, e.g., for ten minutes or longer, followed by a timed cooling cycle, e.g., for about 6 minutes. Where longer or shorter cycles are desired, the timer can be adjusted or can be replaced by a timer giving the appropriate burning and cooling cycles.
  • waste would be stored in the combustion pot until it reaches capacity. A two or three hour burn cycle thus would be employed followed by static cooling by convection.
  • Burner 128 draws secondary combustion air through vents 138 in a rear wall 140 into a chamber 141, thence through a cylindrical sleeve 142 within which burner 128 is mounted.
  • the sleeve surrounds and is spaced from the burner.
  • Air is also drawn into chamber 141 through bottom openings 146 from an air space 144 beneath the lower cabinet 104. This serves to keep a moving blanket of air in chamber 144 to prevent overheating of the floor on which the device rests.
  • Air also is drawn into chamber 141 through opening 150 from the space 148 within the lower cabinet 104 to produce a cooling effect on the outer surface of combustion pot 126.
  • the sleeve 142 consists of a tubular member composed of heat resistant insulation for protecting the burner 128 from the heat of the exhaust gases flowing through conduit 152. It will be seen by reference to FIG. 2 that the combination of conduit 152, sleeve 142 and burner 128 is offset to one side of the center line of the combustion pot 126 for the purpose of producing a swirling flame within the combustion pot 126. It will also be noted with reference to FIG. 1 that the sleeve 142 is mounted below the center line of conduit 152 in order to get better direction of the flame downwardly into the combustion pot and more positive direction of combustion gases upwardly through duct 154 thereby providing a hotter flamewithin the combustion pot.
  • the port is provided with a cover 162 which is constructed to block entry of water into chamber 144 and duct 154, such as might otherwise result from movement of a ship or simply from gusts of wind. Pressure changes from air movement are balanced by the close proximity of vents 138 and exhaust port 160. Disposed behind cover 162 and extending laterally thereof is a screen 164 which also assists in stopping back drafts. A baffle 166 is provided in the upper portion of chamber 141 to assure proper direction of exhaust gases from opening 158 through port 160. The gases flowing from opening 158 through port 160 also will tend to draw cooling air into and through chamber 141. The cooling air in chamber 141 serves to cool the exterior surface of duct 154.
  • FIG. 4 shows a modified structure wherein the conelike side wall 113 terminates in a tubular lip portion 190at the bottom end thereof.
  • the disposable cup or liner 120 which may or may not abut the slide valve member 114, again is-shown to provide for receiving waste product.
  • the cup 120 will be delivered into the combustion chamber along with the waste product.

  • FIG. 5 illustrates another form of toilet in accordance with the present invention which utilizes a modified receptacle and slide valve system. More particularly the receptacle side walls 202 have been formed with curvatures to appear more aesthetic. Curvature also minimizes splash back during use of the device. As with the structure shown in FIGS. 1 through 3 the receptacle can be lined with paper or a suitable preformed paper cup may be utilized. Alternative, or additionally, the receptacle side walls 202 may be coated with a suitable nonstick or release material, such as silicon or Teflon. In addition the bottom edge of the side wall 202 is provided with a silicone rubber lip or seal 204 which rides against the top of slide valve 114. The seal 204 preferably extends 360 around the entire bottom edge of wall 202 to seal off odors and gases from the combustion pot. However, sealing only at the front portion may be employed to hold a small amount of flush water, when desired.
  • the device shown in FIG. 6 is similar to those described above except that it has an additional support plate 232 and a support ring 234 for locating the lower end of the receptacle wall 202 and supporting the receptacle at its lower end.
