12 Claims. (Cl. 4-131) This invention relates to an apparatus and method for processing and disposing of waste matter. It relates particularly to a disposal toilet for waste of the human body, for installations under conditions such that no sewer connection is available. Such is always the case with moving vehicles. A sewer connection may also be unavailable or impracticable in stationary buildings in temporary or permanent locations and the invention is suitable for such installations if permitted by the local sanitary and housing regulations.

The problem posed by the disposal of body waste on moving vehicles has been troublesome to designing engineers. The problem has probably been least troublesome on railroad trains, since the toilet rooms can be locked in populous areas and the waste can be discharged on the railroads own right of way from fast moving trains with little objectionable result. The difficulty of the problem is greater in the case of busses and house trailers traveling over public rights of way, and reaches its greatest magnitude in aircraft. Discharge over land areas at low altitudes is obviously undesirable, and even in the case of discharge over bodies of water or at high altitudes over land, the relative wind velocity of the aircraft and surrounding air of the slip stream is great enough to make the projection of waste matter away from and apart from contact with the surface of the craft impossible without use of devices which will create a serious drag.

An apparatus for satisfactory disposal of waste of the human body has been disclosed in an application Serial No. 190,020, filed October 13, 1950, by Edward H. Simpson and Gordon Deckman for Excreta Disposing Toilet, since matured into Patent No. 2,678,450, dated May 18, 1954, and assigned to O & M Machine Company, Inc., the assignee of the present application. The inventions of that application and of this present application are particularly adapted to the disposal of waste from aircraft in transit. In this field of waste disposal, it is objectionable to discharge any of the waste matter as a liquid or in the form of solid particles of appreciable size and relatively high specific gravity. But, when finely comminuted and changed to substances of low specific gravity as provided in the inventions of these two applications, the solid particles I settle slowly to earth, in dispersed relationship. Air resistance checks their falling speed to a rate much less than the free fall speed of gravity, and disperses the particles over a wide area.

The inventions disclosed in both applications are therefore designed to convert the waste matter into vapor and finely comminuted solid particles and widely scatter the vapor and solid particles through a discharge vent from the fast moving aircraft. In the processing treatment, the waste matter is also thoroughly sterilized when subjected in its finely divided state to the temperature required to convert it to vapor and ash dust. Within the broad concept of a process for total sterilizing reduction of the waste matter to vapor and ash dust are embraced diiferent operational sequences in which the variants are the amount of the charge processed at a time, the order of the steps of heating, homogenizing, comminuting and dissipating, the time duration interval of each step of the process, and the chronological relation of that time interval to the time intervals of the other steps, i. e., whether alone, simultaneously, or in overlapping relation. The kind of control of the sequence which is used for beginning and terminating each step may also be varied. The former application presents certain similar sequences of operations and certain control arrangements for the conversion of the waste matter into sterilized vapor and ash dust, and apparatus for effecting these operational sequences and controls. In this application another sequence of operations for this purpose of an overall dilferent character and an apparatus therefor, is disclosed with advantages and benficial results which will be developed in the course of the following description.

The invention is not limited to the particular embodiment thereof shown and described herein or to any other specific embodiment, nor is the invention limited to the details of the processes herein disclosed but embraces all apparatus and processes coming within the definitions of the appended claims.

The numeral 11 designates a floor which may be that of an aircraft, a land traveling vehicle or a stationary building. Since the invention is especially adapted for aircraft, the floor will be considered in the following description as that of an aircraft and the description of the apparatus and processes generally will be presented with reference to use on aircraft.

The apparatus may be considered generally as comprising a waste receiver 10 disposed above the fio-or 11 and a waste processor and disposer 50 arranged below the floor .11. A toilet bowl casing 12 (see Figures 1, 3 and 6) of generally cylindrical shape is reinforced at its upper edge with a flange 13 and at its lower edge with a flange 14 by which it is suitably secured to the floor 11. Bars 15 are secured to the casing. 12 as by spot welding and serve as supports for a hinge pin 16 as shown in Figures 2 and 6. A toilet seat 17 is mounted on this hinge pin to swing from a closed position to an open position as indicated in Figures 1 and 6. This seat cylindricalportion 21a permanently attached to' each other in any suitable vmanner. The upper edge ofthe upper portion 21a of thebowl is horizontally outwardly flanged at 22 to form a circular rest for the seat 17. Thesheet metal of which the upper portion 21a of the bowl is made is also horizontally inwardly flanged to form a ledge onwhich is mounted a flush ring 23 having conventional perforations 23a. This flush ring' is supplied with flush water through a hose 24in the following manner.

A pump cylinder 25' as is best illustrated 'in- Figures 6 and 9 is mounted on the floor ll within the casing 12. A piston. 26 moves downwardly within the pump from anupper normal position as shown in Figure 6 in which it rests upon aspring26a. The piston is reciprocably movedcby a piston rod 27 which passes throughthe cyl-' inder head 26!). The upper end of the piston rod'is hinged at 280 to the lower end of a clevis 28 which is threaded on-the lower end of an actuating rod 27a, the latter extending up through a suitably disposed aperture in the upper portion 21a of the toilet bowl and engaging at its upper end the underside of the seat 17.

The pump chamber 32 is ported at each side..for communication-with the check valves 29 and 30, respectively. The conduit 24 connects the check valve 29 with. the flush ring 23 and the check valve 30 is connected by an intake hose 31 to a water supply (not shown), preferably an overhead container from which thewater flows by gravity. The check valve 30 permits the passage of water from the water supply through the hose 31 to the pump chamber 32 and prevents the flow of water in the opposite direction. Similarly the check valve 29 permits passage of water to the flush ring and prevents retrograde movement of the water to the pump chamber.

When the toilet seat 19 is occupied and therefore depressed, the piston 26 is forced downwardly by the piston rod 27 and actuating rod 27a, compressing the spring 2611, water being thereby drawn into the pump chamber through the check valve'30. When the toilet seat 17 is again free to move upwardly, the-piston 26-under the action of the spring 26a moves upwardly forcing the water which has flowed into the pump chamber 32 through the check valve 29 to the flush'ring23.

The lower end of the bowl 21 is shaped with aneck which fits closely within a circular flange 37 which is a part of a housing 36. The housing 36 is generally cylindrical in shape with its axis disposed horizontally. Within the cylindrical chamber thus provided is encloseda cylindrically shaped hopper 33 having acircular opening 34 which is of a diameter about equal to that of the neck of the bowl 21. walls and a cylindrical side wall connecting the endwalls so that the chamber within itis completely enclosed excepting for the opening 34. It is held in place against horizontal longitudinal movement within the housing 36' by the circular end plates 38 which have threaded engagement with corresponding flanged open ends of 'the housing 36. The housing has a circular flange 37a at its lower end by which it is bolted or otherwise secured to the floor 11. The chamber 35 within the housing 36 communicates as may be seen in Figure 3, at its upper end through the circular flange 37 with the toilet bowl 21 and communicates at its lower end throughthe flange 37a with an opening 49 in the floor 11 and through this opening with the interior of the waste processor and disposer 50.

The hopper 33 has axially extending and preferably integrally formed stub shafts 39 which rotate within central bearings in the end plates 38 and each of which has rigidly mounted thereon a spur gear 40. Each'of these spur gears meshes with an associated sector gear 41 as This hopper has circular vertical end I seen in Figures 3, 6 and 9. The two sector gears are clamped by bolts 44 to a cross-shaft 43 which is supported for oscillatory movement by the cars 42 extending outwardly from the housing 36.

The sector gears are operated by a lever 46 which is keyed or otherwise fixedly attached to the shaft 43 and extends outwardly through a slot 46a (Figure 9) in the casing 12 and carries at its outer end a pedal 47. A wire spring 45 bent to the form of a bell crank lever encircles the shaft 43 and is disposed with one looped end catching the underside of the lever 46 and the other free ends engaging the underside of the housing 36; This spring 45 holds the lever 46 and pedal 47 resiliently to their uppermost position and the sector gears 41 to their corresponding lowermost position in which the hopper 33 is positioned with its opening 34 directed upwardly in communication with the toilet bowl 21. After use of the toilet, the user depresses the pedal 47 inverting the hopper 33 and discharging the contents of the hopper into the waste processor and disposer beneath the floor 11.

The waste receiver which has been described above is mounted above the floor 11 in the particular installation used to illustrate the invention. The waste processor and disposer 50 is secured to the underside of the floor 11. This relative location of the receiver 10 and processor and disposer 50 however is not essential to the invention.

An annular flange 51 of angle iron section is seated in a circular aperture 49 in the floor 11. This flange is of the same diameter as the neck 37a of the housing 36 above the floor and is axially alined with the neck 370. A compressible elastic O-ring 51a provides a liquid-tight connection between the flange 48 at the lower end of the neck 37a.

The several devices of the processor and disposer 50 are mounted'either directly on the underside of the floor 11 or on a frame structure which is attached to and depends'from the floor 11. This frame structure comprises a ring 52 of angle iron cross-section,.four channelsectioned uprights 53, 54, 55 and 56, and a built-up diskshaped frame 57 secured to the lower ends of these uprights. The frame 57 consists of a top plate 58, bottom plate 59 and a cylindrical'side wall 60 connecting the top andbottom plates and secured thereto by suitable flange members.

A reservoir 61 of elliptical horizontal section is bolted directly'to the underside of the floor 11. This reservoir has a bottom wall 62 and an elliptically shaped side wall 63 .the upper edge of which is flanged for securement to the floor 11. The aperture 49 opens into the chamber of this reservoir.

An outlet fixture 64 is placed in the bottom wall 62 of the reservoir. This fixture supports a screen 65 across the central opening of the fixture and provides the tapped hole by which an outlet elbow 66 is secured to the bottom of the reservoir.

An agitator 67 is mounted on a shaft 68 to rotatejust above the screen 65 in the outlet fixture 64, as is best shown in Figures 3 and 5. The shaft 63 is mounted in the frame of a motor assembly 69. The axis of the motor and shaft are inclined at a substantial angle to the vertical and horizontal. The motor assembly 69 is mounted partially without and partially within side wall 63 in a manner to exclude liquid from the motor chamber and gear box and to prevent leakage through the wall 63 of the reservoir. The motorwithinthe motor assembly 69 is connected as will be explained below, through a control switch with avoltage supply means by the conductors ina cable 70 (Figure 5).

A microswitch 71 is mounted on and outside of the reservoir wall 63 .bya pairof brackets 72. Anoutwardly spring-urged "pin 73 bears against a flexible diaphragm 73a WhiCh'ilS clamped in position to overlie a small opening.73b in: the reservoir side wail 63.

Alsomounted on the'inner side ofthe reservoir side wall 63 are'aipaircf bracl ets74a betweeniwhich is supported a hinge pin 77. The vertical arms of yoke 76 are hinged upon this pin and support between them a block 75 which is fixedly related to the yoke. A threaded actuating pin 74 is mounted for longitudinal adjustable movement in a threaded bore of the block 75, its outer end bearing upon the inner surface of the diaphragm 73a in alinement with the switch pin 73.

The U-shaped yoke 76 and the block between the arms thereof is in the nature of a leg of a bell crank lever hinged about the pin 77. The other leg of the bell crank lever is a pair of elliptically contoured bars 73 rigidly secured to and extending outwardly from the lower ends of the yoke 76 across the reservoir to a block 79 to which their other ends are pivotally secured on a horizontal axis by means of a hinge pin 80 as best seen in Figure 4. The block 79 is threadedly attached to the upper end of a rod 82 (Figure 3) which carries at its lower end a float 81. The block 79 as shown in Figure 4 also has secured to its upper end a pin 79a which projects through a guiding aperture in a bracket 83 bolted to the reservoir side wall 63.

The float 81 rests upon a spring 84 which is bolted at its inner end to the interior of the bottom wall 62 of the reservoir. The level of the end of the spring which supports the float 81 may be adjusted by means of the screw 84a.

Waste matter within the reservoir 61 is pumped therefrom through a conduit 86 (Figure 3) by a pump 85 and delivered by the pump through a conduit 87 to an incinerating chamber 88. This chamber 88 is enclosed by a top wall 89 suitably mounted between the side walls 60 of the frame 57 at a level intermediate the top and bottom walls 58 and 59 respectively of the frame 57. A bottom wall 90 and cylindrical side wall 90a of the incinerating chamber 88 are suitably mounted in depending position below the top wall 89.

Embedded within the bottom wall 90 is a heating element 91 whichas is best illustrated in Figure may consist of two heating conductor elements electrically connected in parallel with the current source by conductors within a sheathing pipe 107. The flow of current in the heating element 91 is controlled by a thermostat 92 inserted in the body of the bottom wall 90.

A scraper 94 consisting of a single metal blade is mounted on the lower end of a block 95 which is in turn secured to the lower end of a shaft 96. The shaft 96 is rotatably supported in a bearing box 104 and is driven by a motor 97 through reduction gearing in a gear box 98.

The blade of the scraper 94 extends across the bottom of the incinerating chamber 88 with sufficient clearance between its ends and the side wall 90:: to allow for free rotation of the blade and with its lower edge in scraping contact with the bottom wall 91). Since, as will presently appear, the waste matter is discharged from conduit 87 into the incinerating chamber 88 eccentrically of the middle point of the blade 94, at a time when the blade is stationary, small recesses 94a are provided in the lower edge of the blade for flow of the waste matter therethrough and its shallow distribution over the floor 98 of the incinerating chamber. A more complete and rapid incineration of the Waste matter prior to the rotation of the scraper blade is thereby secured. The recesses 94a on one side of the center of the blade are staggered with respect to the recesses on the opposite end of the agitator blade so that the entire area of the surface of the bottom wall 90 may be scraped in the course of one complete revolution of the blade.

The motor 97 also drives a blower 181 through the reduction gearing in the gear box 102. This blower draws in air from the outside through the air intake conduit 180 into the air conduit 99 thence through port 109 into and across the incinerating chamber 88 and out from the incinerating chamber 88 through the exhaust vent pipe 183 to the outside air. A check valve 108 spring biased to its closed position is provided at the lower end of the air conduit 99 to prevent passage of any material from the incinerating chamber 88 at times when the blower is not in operation.

Figure 11 illustrates schematically the various elements of apparatus of this invention and shows the control devices by which these several elements are sequentially operated. The operation of the apparatus and the processing method of the invention will be described with particular reference to Figures 11, 12 and 13.

With the toilet in the position shown in Figure l, and the hopper 33 in the position shown in Figure 7, the apparatus is in normal condition ready for use. When the cover 19 is lifted and the seat 17 moved downwardly by the weight of the .user the rod 27 and piston 26 are depressed causing flush water to flow into the pump chamber 32. After use, the piston 26 is moved upwardly by the expansion of the compressed spring 2641 forcing the water in the pump chamber through check valve 29 and hose 24 to the flush ring 23 and through the perforations thereof to flush the bowl.

Upon leaving, the user depresses the pedal 47 from the position shown in Figure 7 in the direction of the arrow to the position shown in Figure 8. This down ward movement of the pedal 47 which is against the action of the spring 45 causes the sector gear 41 to rotate the hopper 33 in a counterclockwise direction as the hopper is viewed in Figures 7 and 8, inverting the hopper to the position shown in Figure 8 in which position the contents of the hopper are discharged through the opening 34, as indicated by the arrow 126, into the receiving reservoir 61 through the neck 37a and the floor aperture 49. At this juncture the agitator 67 and pump 85 are stationary. The waste matter discharged into the receiving reservoir 61 resulting from several uses of the toilet accumulates in the reservoir. As the level of this waste matter rises the float 81 moves upwardly. When the float reaches a predetermined level the pin 73 of the microswitch 71 will have been moved against the action of its biasing spring to the left, as viewed in Fig. 5, by the action of the loop 78, yoke 76 and actuating pin 74 to close the contacts 127 of the microswitch.

Referring now to Fig. 12, it will be seen that closing of contacts 127 completes a circuit from a voltage supply 132, having one terminal grounded, through lead 141 including a manually operated switch 133 which is closed during flight, lead 142 switch 71, lead 143, a motor 128 of a timer 129, leads 144 and 145 to ground so as to energize the timer motor 128. Operation of timer 129 results first in closing of a switch 152 which completes a circuit from the ungrounded terminal of supply 132, through leads 141, 153, and 154 to the motor 128 in shunt with the circuit comprising lead 142, switch 71, and lead 143 so that timer motor 128 will continue to operate after opening of switch 71 by emptying of the reservoir 61 as described below. After closing of switch 152, the timer closes a switch 147 to complete a circuit from the lead 154, connected, as described above, to supply 132 through leads 141, and 153, through a relay 146, leads and 145 to ground. Relay 146 is thereby energized and its normally open contacts 146' are closed completing a circuit from supply 132, through leads 141, 78', 78, the latter having the contacts 146' and agitator motor 69 connected therein, and lead 145 to ground. The resultant energizing of motor 69 puts into operation the agitator 67.

After a predetermined period of time, say 45 seconds, during which the contents of the reservoir 61 are thoroughly stirred to a homogeneous, semi-liquid consistency, the timer opens switch 147, to break the energizing circuit to agitator motor 69, and immediately thereafter closes switch 148 to complete a circuit from lead 154, through the switch 148, a relay 149, and leads 156, 155, and 145 to ground. Relay 149 is thereby energized and its normally open contacts 149' close completing a circuit from supply 132, through leads 141, 79', 130, pump motor 35 connected in the latter lead, and lead 145 to ground whereupon the contents of the reservoir 61 are pumped into the incinerator chamber 88.

After another predetermined time interval, say three seconds, the timer opens switch 148 to stop pump motor 85.

The aforedescribed closing of switch 133 at the start of a flight will have completed a circuit from supply 132, through leads 141, 158, a relay 159, lead 166, thermostat 92, and a lead 160 to ground to energize the relay 159 and close its normally open contacts 159. Closing of contacts 159 completes a circuit from supply 132, through leads 141, 107, heater elements 91 in lead 107, and lead 145 to ground to energize said heater elements so that the waste material which is pumped into the incinerator chamber 88' during the above described operation of pump motor 85 will be heated to a high temperature. The waste material is thus heated for a predetermined period of time suflicient to insure complete vaporization of the liquid content and complete reduction to ash of the solid content of the waste material.

At the expiration of this latter period of time, which may, for example, be four and one-half minutes, the timer acts to close switch 150 to complete a circuit from lead 154-, through a relay 151, and leads 157, 156, 155 and 145 to ground. Relay 151 will thus be energized to close its normally open contacts 151 whereupon a circuit is completed from supply 132, through leads 141, 76, 131, the blower and scraper motor 97, and lead 145 to ground so that blower 191 (Fig. 11) will be driven to produce a strong air flow into the air intake 100, as indicated by the arrow 134, through the air tube 99, through the incinerating chamber 88, as indicated by the arrows 135 and 136, and out the exhaust pipe 103 to a suitable discharge vent, not shown, to the exterior of the aircraft. Motor 97 will also rotate scraper blade 94.

Rotation of scraper 94 causes loosening and pulverizing of the ash produced by heating of the waste material and also tends to bring the pulverized ash into the path of the airflow through the incinerator so that said ash will be carried along with the airstream and discharged into the atmosphere.

Motor 97 continues to operate for a period of time, say fifteen seconds, sufiicient to assure substantially complete removal of the ash from the incinerating chamber after which the timer reopens switch 150 to stop motor 97.

A cycle of operation is now completed and the timer reopens the switch 152 to break the aforedescribed shunt or auxiliary energizing circuit 153, 154 to motor 128. lf the float controlled microswitch 71 has been opened by dropping of the liquid level in reservoir 61 during the previous pumping operation, this opening of switch 152 will deenergize the timer motor 128 and the timer will come to rest in a position wherein it is conditioned to effect a repetition of the above described cycle of operation upon subsequent closing of microswitch 71 by filling of the reservoir 61.

if, however, frequent usage of the toilet during a given one of said cycles results in the reservoir 61 being filled at the termination of the given cycle, microswitch '71 will be in its closed condition and the timer motor 128 will continue to operate after opening of switch 152. it will be evident, therefore, that the processing and disposing cycle will be automatically repeated until the level in the reservoir has fallen to such a point that the float controlled switch ill is in its open position when switch 152 is opened at the end of a cycle. The complete processing and disposing cycle may take, for example, six minutes.

The apparatus of this invention presents several novel features. As examples of these features it will be noted that it provides for operation of the processing devices, i. e., the agitating, the incinerating, and the disposing devices, only upon the accumulation of a predetermined quantity of'waste matter and not upon each use of the toilet. This has several advantages. it reduces the power consumption and makes it possible to accurately regulate the time intervals of the various processing operations and proper treatment of the waste matter.

The waste matter is thoroughly agitated and given a homogeneous mix of the flush water and the waste matter prior to its introduction into the incinerating chamber. The pumping operation does not begin until this mixing operation has been completed. A smooth rapid flow is thus insured. The pumping operation continues for a time interval just sufficient to complete the conveyance of the waste matter from the receiver to the incinerating chamber which is maintained continously at a high temperature.

The agitator and blower are not operated until after a predetermined time interval in which the several motors are out of operation. Thus the incinerating period may be adjusted to sufficient length for thorough vaporization of the liquid and thorough reduction to ash of the solids of the waste matter. Thereafter the blower is brought into action and simultaneously the scrapper and agitator blade 9 is rotated to bring all of the solids in the incinerating chamber into the path of the moving column of air as it crosses from one side of the incinerating chamber to the other.

This separation of the times of operation of the varions functional devices of the processing and disposing part of the apparatus makes it possible to insure complete vaporization and complete reduction to ash of low specific gravity, of the entire waste matter handled by the apparatus of the invention.
