15 Claims, 11 Drawing Figures PATENTEBHAYZYIQYS SHEET 8 (if 6 FIG INCINERATING COMMODE CROSS REFERENCE TO RELATED APPLICATION This application is a continuation-in-part application of prior U. S. application, Ser. No. 134,650 for INCIN- ERATING COMMODE, filed Apr. 16, 1971.
BACKGROUND OF THE INVENTION The invention relates to an apparatus for use in disposing of human waste. More particularly, this invention includes an incinerating commode wherein incineration converts solid waste to an ash and removes the water content of the waste.
In the field of human waste disposal, a number of methods have been employed for disposing of the solid and liquid waste. Commonly, sewage treatment plants are provided which are connected via sewage pipelines to domestic and commerical facilities. As population has increased, the capabilities of the sewage treatment plants have been severely strained and many such plants have been unable to satisfactorily process the increased waste of the community. Such inadequacy of sewage plant facilities has necessitated the expansion of facilities at great expense to the taxpayers. In addition, the inadequacy of the sewage treatment facilities has also led to the pollution of streams and rivers normally used for water supply and recreation facilities.
In remote areas where sewage treatment facilities are not available. septic tank means are often employed to dispose of the human waste. A septic tank utilizes bacterial action in the tank to dispose of solid waste and utilizes a subterranean drainage field for disposing of the liquid waste. However, in certain areas where the soil conditions are not satisfactory, utilization of septic tanks creates unhealthy conditions in their use. A number of municipalities have adopted strict codes to regulate the use of septic tanks.
In remote areas where a sewage treatment facility is not available and wherein septic tanks are not feasible, oxidation ponds are employed to dispose of human waste. In utilizing oxidation ponds, a fungus is utilized to dispose of the solid waste with the liquid waste being disposed of through evaporation or surface drainage means. The use of oxidation ponds requires a large ground area and is unattractive in appearance.
A number of attempts have been made to devise chemical and incinerating commode facilities for use in disposing of human waste. However, the prior art chemical and incinerating human waste disposal apparatus are extremely complex in construction and operation, uneconomical to manufacture and unreliable in performance.
SUMMARY OF THE INVENTION The above disadvantages of the prior art have been overcome by the present invention which basically includes an upwardly open commode body disposed above an incinerating combustion chamber wherein the human waste can be deposited in the commode body and transferred by gravity into the combustion chamber. The combustion chamber includes waste comminuting means for reducing the particle size to human waste to be incinerated and includes heat source means operative for incinerating the comminuted human waste.

The additional closure lid 190 is horizontally oriented and is supported along its lateral side edges by a pair of inwardly directing guide tracks 191, 192, as shown in FIG. 3, and above combustion chamber top wall 104. Lid 190 is operable for movement from an open position in which the material transferred through commode body discharge opening 25 can fall by gravity into the combustion pot 110 and is movable to a forwardly closed position wherein the forward edge of the lid is in sealing contact with the upper surface of the burner nozzle flared housing 185, as shown in FIGS. 2 and 4. When the lid 190 is in the forwardly advanced closed position, the combustion chamber will be effectively sealed so that the flame or heat source means developed by nozzle 180 will be confined within the area of the combustion chamber and the combustion pot. Lid 190 is spring biased to an open position by an elongated tension spring 194 which is connected adjacent one end to an upstanding pin 195 on lid 190 and is connected at its opposite end to an upstanding pin 196 of the housing structure. Lid 190 is moved to a forward closed position by means of an actuator linkage mechanism which is operatively associated with the commode closure lid 135.
As shown in FIGS. 2, 7 and 8, the actuator linkage mechanism is generally represented by the reference numeral 200 and includes a first lever member 201 which is fixed to an extended end of hinge pin 33 such that angular movement of lid 35 will effect corresponding angular movement of lever 201. An extended end of lever 201 is connected by a conventional pin means 202 to a pair of link members 203, 204. Opposite ends of link members 203, 204 are connected by pin 205 to a control lever 206. Control lever 206 is pivotally supported at an intermediate position by a pin 207 which is supported between a pair of housing wall members 208, 209. An opposite end of control lever 206 is provided with a spring loaded actuator member 210. Actuator member 210 is slidably supported within a sleeve 211 and is spring biased to an outwardly displaced operable position by a compression spring 212.
When lid 190 is advanced to a forward closed position. the lid is latched in the closed position by a latch mechanism generally represented by the reference numeral 220. The latch mechanism 220 includes an elongated link member 221 which is supported for vertical translating movement in a pair of vertically spaced support members 222, 223. Latching link 221 includes a bottom edge 224 which is supported on the upper surface oflid 190 and will permit lid 190 to slide therebeneath during movement to the forward closed position. When lid 190 is advanced to a complete closed position, elongated link 221 is spring biased into position behind the rear edge of the lid 190 to maintain the lid in a closed latched position. Latching link 221 is moved to an unlatched position by means of an elongated lever 230. Lever 230 is pivotally supported by a stud shaft 231 provided on housing wall structure 209 with one end of lever 230 being provided with an elongated slot 232 which receives a horizontal pin means 234 formed on latching link 221. An opposite end of lever 230 is pivotally connected by pin means 235 to a solenoid plunger element 237. Solenoid plunger 237 is operatively supported for reciprocating movement within a conventional electrically operable solenoid means 238, with the plunger 237 being biased outwardly by a conventional compression spring means 239. The compression spring 239 will operate to effect counterclockwise biasing movement of lever 230 which will provide a biasing pressure on latching link 221 such that the latching link will automatically move downward to a latched position behind the rear edge of closure lid 190 when the lid is moved to the forward closed position by control lever 206 and actuator member 210.
When solenoid 238 is energized, lever 230 will be angularly dispaced in a clockwise direction causing the latching link 221 to be lifted to a position above the rear edge of closure lid 190 allowing the tension spring 194 to bias the closure lid 190 to the rearwardly displaced open position.
Referring now particularly to FIGS. 2 and 3, the incinerating commode 10 includes a vertically oriented transfer conduit means 250 supported between the discharge openings 25 formed in the commode body 20 and the receiving opening formed in the combustion chamber above combustion pot 110. The vertically oriented transfer conduit means 250 includes a pair of side wall structures 251, 252, a front wall structure 253 and a rear wall structure 254. The rear wall structure 254 includes an opening 255 which is in flow communication with a discharge conduit 256 of a blower means 260.
As shown in FIGS. 7 and 8, the blower means 260 is supported and driven by a conventional electric motor means 265. The motor means 265 includes conventional drive shaft means (not shown) extending from opposite ends thereof, with one shaft being operatively associated with blower 260 and with the other end of the shaft being operatively associated with air blower means 270. The air blower means 270 includes a discharge conduit means 271 which is connected in flow communication with the burner nozzle mixing valve 182.
In operation, the blower 270 will develope air pressure through conduit 271, mixing valve 182, conduit 181 and to the burner nozzle 180. When the burner nozzle 180 is ignited and supplied with fuel, the burner nozzle will develope a pressurized heat source means within the combustion chamber and combustion pot to effectively incinerate any waste products contained within the combustion pot. The air blower means 270 is cyclically controlled such that after the waste contained within the combustion pot 110 has been effectively incinerated, the burner nozzle 180 will operate to extinguish the flame, with the blower continuing to operate to purge the waste by-products of combustion, including combustion ash and unburned fumes, outwardly through the discharge conduit means 105 and will continue to operate to cool the combustion chamber to a predetermined temperature.
Since the air blower means 260 is operated by the same shaft from electric motor 265, blower 260 will also be operated during an incinerating operation to develope a supply of cooling air which is discharged through conduit 265, opening 255 into the vertically oriented passageway 250. The coolinjg air forced into the passageway 250 will be allowed to excape around the upper edges of side walls 251, 252 and front wall 253. The cooling air developed by blower 260 will then flow through a passageway defined between combustion chamber side walls 101, 102 and additional horizontally spaced upright wall means 101a, 102a (FIG. 3). The passageway formed between walls 101 and 101a and 102 and 102a will allow the cooling air developed by blower 260 to be discharged out and around the combustion chamber discharge conduit 105 to aid in maintaining the area surrounding the combustion chamber sufficiently cooled during an incinerating operation.
As shown in FIGS. 1, 2, 6, 10 and 11, the incinerating commode includes a number of electrically operable control elements for use in controlling cyclic operation ofthe incinerating commode. FIGS. 2, l and 11 shows a latch mechanism 300 for use in maintaining the commode closure lid 35 in a closed latched position during an incinerating operation. Latch mechanism 300 includes a latching block 301 slidably supported by a pair of angle track elements 302, 303 beneath housing top 16. Latchingblock 301 is adapted to be moved from an unlatched position horizontally displaced relative to control lever 206, to a latch position supported in alignment with and operable for blocking counter-clockwise movement of central lever 206. Movement of latching block 301 is controlled by a pair of solenoids 304, 305 which supports a common reciprocatically operable plunger 306. Plunger 306 is connected to a bracket 307 which is fixed to latching block 301. Operation of solenoid 304 will effect movement of latching block 301 to the aligned control lever blocking position and operation of solenoid 305 will effect movement of latching block 301 to an unlatched position.
As shown in FIGS. and 11, the solenoid plunger 306 is operatively associated with a double pole switch means 310, such that when solenoid 304 is operated to move the latching block to a latching position, switch 310 will be moved to an on current conducting position and operation of solenoid 305 will effect movement of switch 310 to an of nonconducting position. One pole of switch 310 is operatively connected to blower motor 265 and a second pole of switch 310 is operatively connected to the comminuting drive motor 147. Cornminuting drive motor 147 also includes a second switch means 311 (FIGS. 4, 6 and 11) which is located adjacent housing side wall 15 and in alignment with comminuting plate support rod 158. Switch 311 is moved to an of nonconducting position when contacted by rod 158 and will ensure that the comminuting plates 122, 123 are always stopped in an outermost horizontally spaced position after completion of an incinerating cycle of operation.
Operation of solenoid 304 is controlled by switch means 312 (FIGS. 2 and 11) which is supported above a rightmost extended end of latch control lever 230 and is operable for sensing when the latching link 221 has moved to a latching position after closure of lid 190. Operation of solenoid 305 for moving the latching block to an unlatched position is controlled by a low temperature sensing switch means 313 which is located of the outside of combustion pot wall 113. Low temperature sensing switch 313 is a conventional pulse operable switch and is operable for conducting an operating pulse to solenoid 305 when the temperature of the combustion pot has droped to a predetermined temperature after an incinerating operation.
The incinerating commode control means includes a conventional fire box control means 315 (FIGS. 2 and 11) which is operatively connected to mixing valve 182 and burner nozzle for controlling the input of fuel and the ignition of burner nozzle 180 during an incinerating operation. As shown in FIG. 11, fire control box 315 is electrically connected in series with an air flow operating switch 316 and a high temperature sensing switch 317. The air flow sensing switch 316 is located in the discharge conduit 105 and is operable for sensing operation of the blower means 260, 270 and ensures that the burner nozzle cannot be operated without the blower means operating. High temperature sensing switch 317 is located on the outside combustion pot wall 113 adjacent low temperature sensing switch 313 and is operable to sense a high temperature of the combustion pot which would be set to ensure that all the waste contained in the combustion pot had been completely incinerated and after a predetermined high temperature had been sensed, would operate to stop the operation of burner nozzle 180. High temperature sensing switch 317 is operatively associated with solenoid 238 and will operate when a predetermined high temperature is sensed to conduct an operating pulse to solenoid 238 for effecting movement of latching link 221 to an unlatched position to allow spring 194 to move lid to an open position. Movement of lid to an open position will permit both of the blowers 260, 270 to direct air flow through the combustion chamber for cooling and purging the combustion chamber.
As shown in FIG. 11, the control circuitry includes an on and of master control switch 320 and a lamp means 325. Lamp means 325 is on anytime the blower means 260, 270 are operating to direct air flow through discharge conduit 105 for operating air flow sensing switch 316.
OPERATION In utilizing the incinerating commode embodying the principles of the present invention, the commode lid 35 is raised to an upwardly opened position, the closure lid 190 is in a rearwardly retracted position and the combustion pot lid 170 is in a pivoted upwardly open position to permit human waste deposited in the commode body to be transferred by gravity through the transfer conduit means 250 into the combustion pot 110. After waste has been deposited in the combustion pot 110 a waste incinerating operation is initiated by first effecting operation of the cleansing fluid dispensing control switch 55 to cause a predetermined amount of cleansing fluid to be dispensed through manifold 50 to effectively cleanse the side walls 21-24 of the commode body with the cleansing fluid being discharged through opening 25, downwardly through transfer conduit means 250 into the combustion pot 110.
After the cleansing fluid actuating switch 55 has been operated, the closure lid 35 is moved to a horizontal commode closed position. During movement of lid 35 to the closed position, the actuator linkage 200 will cause control lever 206 to be pivoted in a clockwise direction (FIG. 2) so that the actuator member 210 will contact the rear edge of lid bracket 190a, causing lid 190 to be advanced forward to a closed position. After lid 190 reaches a closed position, the latching link 221 will be spring biased by solenoid compression spring 239, control lever 230 to a downwardly displaced lid latching position to hold lid 190 in a forwardly displaced latched position during an incinerating operation. When latching link 221 moves to a latching position, lever 230 will effect operation of switch 312 to energize solenoid 304, causing the lid latching block 301 to move to a latching position and moving switch 310 to an on' conducting position. Operation of switch 310 will supply power to blower motor 265 and comminuting plate drive motor 147. After blowers 260, 170 have been started air flow sensing switch 316 will operate to allow fire control box to effect operation of the mixing valve 182 and ignition of burner nozzle 180 such that a pressurized flame source will be directed into the combustion chamber as described above.
The burner nozzle 180 will continue to operate until the high sensor switch 317 senses a predetermined high temperature which would indicate that the solid and liquid waste contained in the combustion pot 110 has been effectively incinerated. When the high temperature sensor switch 317 senses a predetermined temperature which would indicate that the solid and liquid waste contained in the combustion pot 110 had been effectively incinerated. When the high temperature sensor switch 317 senses a predetermined temperature, a control signal will be supplied through fire control box 300 to cause the mixing valve 182 to stop the flow of fuel to the burner nozzle 180, thus allowing the burner nozzle 180 to be distinguished. The control signal produced by high sensor switch 317 will also control a supply of input power to solenoid 238 which will energize the effect clockwise angular displacement of lever 230 to lift the latching link 221 upwardly to an unlatched position so that tension spring 194 will return closure 190 to an open position. Simultaneously with the movement of closure lid 190 to an opened position, the counterweight 224 will effect angular displacement of lid 170 to an upwardly extended open position.
The blower means 260, 270 will continue to operate after the flame developed in the burner nozzle has been distinguished causing the air forced through the burner nozzle 180 and the air from blower 260 to cool the combustion chamber 100. The combustion chamber will be cooled to a predetermined low temperature which is sensed by low temperature sensing element 314. When low temperature sensing switch 314 is operated, a pulse will be supplied to solenoid 305 causing the latching block 301 to be displaced to an unlatching position and moving switch 310 to an off" position to stop operation of motors 147, 265. When the blower motor 265 is stopped, airflow through discharge conduit will stop to open air flow sensing switch 316 and turning off lamp means 325 to indicate that an incinerating operation has been completed.
