Toilet assemblies

The invention or inventions involve various sanitary toilet systems, assemblies, subassemblies, embodiments or structures comprising components, the majority of which are relatively light in weight, readily constructed or formed into the shapes and dimensions desired to provide structures which are portable, very durable, economical to manufacture and assemble, and service when required. Although the components may be constructed of any material suitable for the purpose, the majority are preferably made from cellulosic sheet material, some of which are superimposed and permanently joined or bonded together to provide laminated relatively thick stock which is also treated to render the stock substantially liquid proof and very strong, yet light in weight. The weight factor is important because any one of the toilet assemblies can be readily lifted and carried to any location desired. Each of the toilet assemblies embodies, among other things, what may be termed a housing or base, a support or supporting enclosure disposed in the housing, a receptacle located in the enclosure for receiving body waste, a seat mounted in relation to the housing and provided with a relatively large opening in communication with the receptacle, and a cover having a portion for overlying the seat and a portion for disposition in the opening for substantially closing the same. This unique connecting relationship between the seat and cover to close the opening also appears to constitute an advance in the art. One particular feature of the invention is to provide a system in which some of the liquid of the waste in a receptacle is automatically released and dispensed at a remote location such as in a sump buried in the ground.

FIELD OF THE INVENTION 
The present invention relates to improvements in toilet assemblies and is 
specifically directed to a new and improved portable toilet assembly. 
BACKGROUND OF THE INVENTION 
The common approach in prior portable toilet assemblies has been to provide 
units that promote air circulation into the holding area. See, for 
example, Kurrels, U.S. Pat. No. 3,142,847. 
Such portable units, after being used and between uses, produce objectable 
odors. 
SUMMARY OF THE INVENTION 
The present invention provides a toilet assembly for use with a flexible 
liquid-proof receptacle, such as a plastic bag, which comprises a 
structure including a seat, and means for receiving, positioning, and 
captivating the receptacle under the seat. The structure substantially 
closes and seals the interior of the receptacle except for an opening 
through the seat. The seat is formed of slightly compressible foam plastic 
material and defines a downward tapering edge about the opening. A cover 
is provided for the seat that includes a downward projecting edge 
conforming to the opening in the seat for nesting against its edge and 
aiding in sealing the opening. With this construction the toilet assembly 
may be used, body wastes discharge through the opening into the receptacle 
and odors contained within the assembly by placing the cover over the seat 
between uses.

DESCRIPTION OF FIGS. 1-7 
Referring to FIGS. 1 through 7 of the drawings there is disclosed a toilet 
system or assembly generally designated 1 constituting one embodiment of 
the invention or inventions. 
More particularly, the assembly 1, preferably comprises a base generally 
designated 2, a support or container designated 3, a receptacle designated 
4 for human body waste, a seat designated 5, a cover designated 6, and a 
sump designated 7 into which some of the waste may drain from the 
receptacle. 
The base 2 is preferably in the form of a housing having a bottom wall 9, a 
pair of corresponding parallel planar side walls 10 and a pair of parallel 
planar end walls 11. The upper extremities of the side walls 10 are 
preferably reinforced by outer strips or members 12 and the end walls 11 
by members 13. The members 12 and 13 are preferably secured in place by a 
suitable adhesive. A planar platen or panel 14 is disposed in the housing 
on its bottom wall 9 to assist in stabilizing or reinforcing this wall. 
The support 3 is preferably constructed from a single elongated piece of 
sheet material which is suitably creased or scored so that it can be 
readily manipulated or folded to provide a pair of corresponding parallel 
planar side walls 15, an end wall 16 and a pair of corresponding aligned 
planar end portions 17 having edges arranged in a juxtoposed relationship 
to substantially form an end wall parallel to the end wall 16. The upper 
extremities of the side walls 15 and end portions 17 are preferably 
reinforced by internal members or portions 18 and the end wall by 
reinforcing members 18', which are preferably adhesively secured to the 
walls end portion. The support 3 may be mounted in the housing upon the 
panel 14 as depicted in FIG. 4. 
The receptacle 4 is preferably in the form of a liquid proof resiliently 
flexible plastic bag which is generally rectangular in shape and includes 
a bottom wall 19, side walls 20, end walls 21, and upper integral 
outwardly extending flange portions 22, the latter of which are adapted to 
be clamped against the upper marginal edges of the side, end walls and 
portions of the support or container 3 and the members 18 and 18' thereon 
by the seat 5 as depicted in FIG. 4 and which will be described more in 
detail subsequently. The receptacle is capable of holding fifteen gallons 
of human waste or fecal matter but its capacity may obviously be modified. 
As above referred to one of the objects of the invention is to provide a 
unique seat and cover assembly for primary use with the support 3 and 
receptacle 4. More particularly in this respect, the seat 5 is moulded to 
the desired shape from a suitable durable slightly compressible plastic 
material and comprises an upper generally rectangular relatively thick 
planar portion 23 and a lower generally rectangular relatively thick 
planar portion 24 integral with the upper portion. The outer edge portions 
of the upper portion 23 are adapted to rest against the upper edges of the 
support 3 and members 18 and 18' carried thereby, with the flange portions 
22 of the receptacle 4 clamped therebetween as noted above. The side edges 
of the lower portion 24 of the seat are preferably tapered so that this 
portion can be snugly press-fitted into the container and in order to 
additionally provide for a tight connection and in holding the flanges 22 
of the receptacle in place, the front and rear edges of portion 24 are 
respectively provided with pairs of tapered projections 25. The rear pair 
of projections are shown see FIG. 1. The seat is provided with a generally 
oblong opening 26 which extends transversely through the portions 23 and 
24. The marginal edges of this opening in the upper portion 23 of the seat 
are preferably tapered downwardly and inwardly as indicated at 27 and the 
marginal edges of that portion of the opening in the lower portion are 
tapered downwardly and outwardly as indicated at 28 as shown in FIG. 3. 
The seat at the front of the opening is preferably dished or formed into 
what may be termed a concave area 29, the purpose of which is obvious. 
The cover 6 is also preferably constructed from a suitable plastic material 
and comprises an upper generally rectangular planar portion 30 and a lower 
planar portion 31, substantially conforming to the shape of the opening 26 
in the seat and has tapered marginal edges which serve to substantially 
nest or fit quite snugly into the opening 26 and substantially seal the 
latter and thereby substantially prevent the release of any odors 
emanating from the receptacle 4. The cover may be pivotally connected to 
the seat by a hinge 32 which is preferably in the form of an adhesive tape 
having portions which are respectively secured to the rear portions of the 
seat and cover. 
Attention is directed to the fact that the lower portion 24 of the seat 5 
is located in the receptacle 4 and due to its taper serves to press the 
upper extremities of the receptacle walls against the inner surfaces of 
the inner members 18 and 18' carried by the upper extremities of the side 
and end wall and end portion of the container 3 as best shown in FIGS. 4 
and 6 and the upper portion 23 of the seat serves to clamp the flanges 22 
of the receptacle against the upper edges of the walls of the container 
and member 18 and 18' so that any free portions of the flanges, if so 
desired, may be adhesively or otherwise secured to the reinforcing members 
12 and 13 carried by the base or housing 2. It is believed that this 
clamping of the receptacle in relation to the container or support 3 
constitutes a meritorious advance in the art. 
It should be noted that the seat and cover are preferably constructed of a 
moulded foam plastic material which is light in weight, bouyant, and 
provided with fine or smooth external surfaces whereby to enhance the 
appearance and promote sanitation; that the material defining the opening 
26 in the seat is shaped to promote the warmth and comfort to the buttocks 
of the user, and that the seat is provided with the tapered relatively 
shallow area or recess 29 which slopes inwardly into the opening 26 for an 
obvious purpose and to promote sanitation. 
As alluded to above one of the objects of the invention is to provide a 
toilet system whereby at least some of the liquid of the body waste may be 
separated or drained for deposit within the confines of the housing or at 
a location remote from the toilet assembly. More particularly in this 
regard and referring to FIGS. 4, 5 and 6, the bottom wall 19 of the 
flexible receptacle 4 is manipulated to provide an upstanding generally 
cylindrical formation 33 having a top wall provided with a central opening 
34. A tubular cylindrical fitting 35, preferably constructed of a flexible 
plastic material, has an upper annular flared flexible portion 36 which is 
fixedly secured in an overlapping relation to the top wall of the 
formation 33 to provide a liquid tight connection. The fitting 35 is 
detachably cooperable with a complementary fitting 37 which has a central 
tubular portion 38 which detachably receives the upper end of a length of 
tubing 39, the latter of which may be considered to constitute a 
reservoir. The fitting 37 also has an outer concentric portion 40 
preferably provided with an external annular socket 41 which serves to 
detachably receive a lower annular entering portion 42 of the fitting 35. 
Otherwise expressed, the fitting 37 may be readily detachably connected to 
the fitting 35 whereby liquid in the receptacle may flow outwardly through 
the tubing. 
More specifically, the structure described in the preceding paragraph may 
be referred to as a drain and may include what may be termed a riser or 
prop 43 preferably of a frustoconical character which is located under the 
bottom wall of the receptacle in a rear area of the receptacle. The riser 
is provided with an axial aperture 44 and a lower intersecting radial 
groove 45 through which the tubing 39 extends. The drain is generally 
protected by a cap 46 which substantially covers the cylindrical portion 
33 of the receptacle, the fittings 35 and 37. The cap has a cylindrical 
wall 47 and a top wall 48. The upper extremity of this cylindrical wall is 
provided with a plurality of circumferentially spaced corresponding ports 
50. The arrangement is such that at least some of the liquid of the body 
waste will separate and drain into the tubing through the ports 49 and 50. 
It should be noted that the annular flared flexible portion 36 of the 
fitting 35 serves to resiliently engage the inner surface of the 
cylindrical wall 47 of the cap and assists in frictionally holding it in 
the correct operative position as depicted in FIG. 5. The cap may be 
referred to as a strainer or separator. The tubing is of a sufficient 
cross-sectional dimension and length so that it can be coiled or laid 
between the platen 14 and bottom wall 19 of the receptacle as shown in 
FIG. 4. The free end of the tubing is sealed or closed so that the tubing, 
in effect, constitutes a reservoir for retention of the liquid within the 
confines of the toilet assembly, until one desires to release it or 
dispose of the receptacle and its contents. In FIG. 4 the level of the 
liquid for flow into the drain is illustrated but if desired the 
receptacle can be utilized long after the tubing has been completely 
filled and the drain is closed or covered with body waste. Otherwise 
expressed the assembly shown in FIG. 4 may be referred to as a self 
contained portable toilet assembly or system. 
The disclosure in FIGS. 6 and 7 substantially embodies the structure of 
FIGS. 4 and 5 and is modified to the extent that the tubing 39 is extended 
through adjacent walls of the housing or base 2 and support 3 for 
depositing liquid into the sump 7 at a remote sanitary location from the 
toilet assembly. This sump may be in the form of a well point or structure 
which can be readily driven or buried in the ground. The tubing may be 
extended through the housing and support in different ways but as shown in 
FIG. 1, the lower extremities of the end wall portions 17 of the support 3 
are preferably perforated to provide portions 51 which are manually 
separated from the portions 17 to provide an opening 52 as shown in FIG. 6 
and the lower extremity of the front wall 11 of the housing 2 is 
perforated or constructed to provide a portion 53 and as shown the latter 
is bent downwardly and forwardly to provide an opening 54 aligned with the 
opening 52. Also, as shown in FIG. 1, the upper extremity of the rear end 
wall 11 of the support 3 more or less between the inner members 18' is 
scored or constructed to provide a portion 55 which can be readily removed 
for a purpose to be described subsequently when the support 3 is inverted 
as shown in FIGS. 10 and 19. 
In view of the foregoing it should be manifest that the toilet assembly may 
be utilized as a self contained portable structure whereby at least some 
of the liquid of the body waste can be drained into a reservoir within the 
confines of the assembly so the latter may be termed a self contained 
portable assembly or system and that it can be readily converted so that 
at least some of the liquid may be automatically drained away to a 
sanitary location remote from the assembly. It is also apparent that, if 
so desired, the receptacle and tubing constitute a subassembly which may 
be omitted, in which event the support and/or the housing may be utilized 
for storage. Of further significance are the advantages offered by the 
seat and cover subassembly and appreciably large capacity of the 
receptacle which is preferably of a size to hold fifteen (15) gallons of 
body waste. 
DESCRIPTION OF FIGS. 8-9 
A second toilet assembly or system embodying certain features of the 
invention is illustrated in FIGS. 8 and 9. This assembly comprises what 
may be termed a conventional container generally designated 60 of moulded 
plastic, a resilienty flexible receptacle or bag 61 and a subassembly 
comprising a seat generally designated 62 and a cover 63, this subassembly 
being substituted and utilized in lieu of a conventional cover such as 64. 
The seat and cover substantially include the attributes of the seat and 
cover described above. 
More particularly, the container 60 may be rectangular or square in shape 
and its upper extremities are provided with an internal recess 65. 
The seat 62 is constructed to include an upper rectangular portion 66, a 
lower rectangular portion 67 and a relatively large oblong opening 68 
having an upper downwardly and inwardly extending marginal recess or 69 
area for accommodating the buttocks and a lower downwardly and outwardly 
extending marginal recess or area 70 to promote sanitation. 
The cover 63 includes a lower portion 71 substantially corresponding to the 
shape of the upper recess 69 in the seat for reception therein and an 
upper portion 72 for overlapping engagement with the seat as shown in FIG. 
9. 
The receptacle 61 is preferably in the shape of a generally rectangular 
resiliently flexible bag having a bottom wall 73 and upstanding walls 74 
having upper extremities or flanges which are preferably held in the 
recess 65 between the seat and walls of the container 60 and so that, if 
so desired, portions of the extremities or flanges may be secured to outer 
surfaces of the container by an adhesive as indicated at 75. It should be 
observed that the marginal edges forming the contour of the lower portion 
67 of the seat are preferably tapered in order to assist in forcing the 
upper extremities of the receptacle 61 against inner surfaces of the 
container and thereby obtain a sealed connection to substantially prevent 
the escape of odors between the receptacle and seat and the fit between 
the cover and seat further assists in diminishing the release of odors. 
The seat is also preferably constructed to provide a relatively shallow 
tapered or generally pear shaped front recess 76 which slopes toward the 
opening 68, the purpose of which is obvious. 
DESCRIPTION OF FIGS. 10-18 
In FIGS. 10 through 18 there is disclosed a third toilet assembly or system 
somewhat similar to the assembly illustrated in FIGS. 1-7, except for the 
primary differences that the receptacle is of a smaller size, preferably 
of five (5) gallon capacity, and is mounted in a container, in addition to 
a support or enclosure. 
More particularly, this modified assembly preferably comprises a base or 
housing generally designated 80, a support 81, a container 82, receptacle 
83, seat 84 and a cover 85. 
The base 80 includes a bottom wall 86, side walls 87, end walls 88, pairs 
of members 89 which are respectively secured to the upper extremities of 
the side and end walls for reinforcement purposes. A planar panel 90 is 
arranged for disposition in the housing on its bottom wall for imparting 
greater stability to the base. 
The support 81, which may also be referred to as a container, is preferably 
of an elongated one-piece construction which is creased or scored so that 
it can be folded or manipulated to provide an enclosure comprising a pair 
of corresponding planar parallel side walls 91, an end wall 92 and a pair 
of end portions 93 which substantially form an end wall opposite the end 
wall 92. The lower extremities of the side walls are preferably reenforced 
by members 94, the end wall 92 by a member 95 and the end portions 93 by 
members 96 which are respectively suitably secured to the inner surfaces 
of such extremities. The end portions 93 between the members 96 are 
constructed to provide detachable portions 97 and the upper extremity of 
end wall 92 is constructed to provide a bendable portion 98, the latter of 
which is not utilized in this third toilet assembly. It should be observed 
that the support 81 is substantially the same as the support 3 above 
referred to but is inverted. It should be further noted that when the 
support is positioned in the housing 80 that the portions 97 are located 
opposite the bendable portion 98 provided in an end wall 88 of the housing 
80. 
The container 82 is preferably constructed to provide a bottom wall 100, 
side walls 101, and end walls 102. The bottom wall is provided with a 
bendable portion 103 and an adjacent end wall is also constructed to 
provide a bendable portion 104 as clearly shown in FIG. 13. The upper 
extremities of the side walls are preferably reinforced by members 105 
secured to the external surfaces of these walls and the upper extremities 
of the end walls are preferably reinforced by externally secured members 
106. 
The receptacle 83 is preferably generally rectangular in shape and has a 
bottom wall 107, side walls 108, and end walls 109. These side and end 
walls are extended to form what may be termed generally outwardly 
extending upper peripheral flange 110 which is adapted to overlie the 
upper marginal edges of the walls of the container 82 and the upper 
marginal edges of the pairs of external reinforcing members 105 and 106 
attached to the container. 
The receptacle 83 is preferably constructed of a resiliently flexbile 
plastic material like the receptacle described above, adapted to contain 
five (5) gallons of body waste as stated above, and is provided with a 
drain and/or means for separating at least some of the liquid of the body 
waste. More particularly in this regard and referring to FIGS. 14 and 15 
the bottom wall 107 of the receptacle 83 is formed to provide an 
upstanding generally cylindrical formation 111 having a top wall provided 
with a central opening 112. A tubular cylindrical fitting 113 preferably 
constructed of a flexible plastic material has an upper annular flared 
flexible portion 114 which is fixedly secured in an overlapping relation 
to the top wall of the formation 111 to provide a liquid tight connection. 
The fitting 113 is detachably cooperable with a complementary fitting 115 
which has a central tubular portion 116 which is detachably received in 
the upper end of a length of tubing 117, the latter of which may be 
considered to constitute a reservoir. The fitting 115 also has an outer 
concentric portion 118 preferably provided with an external annular socket 
119 which serves to detachably receive a lower annular entering portion 
120 of the fitting 113. Otherwise expressed, the fitting 115 may be 
readily detachably connected to the fitting 113 whereby liquid in the 
receptacle may flow outwardly through the tubing, all of which has been 
previously substantially described. The fittings 113 and 115 and tubing 
117 may be referred to as a drain. 
The structure described in the preceding paragraph may also include what 
may be termed a riser or prop 121, preferably of a frustoconical 
character, which is located under the bottom wall 107 of the receptacle in 
a rear area thereof. The riser is provided with an axial aperture 122 and 
a lower radial groove 123 which intersects the aperture 122 through which 
the tubing 117 extends. The upper end of this tubing is detachable 
connectible to a central tubular depending portion 116 of the fitting 113, 
as noted above, and the free or opposite end of the tubing is preferably 
sealed or closed so that the tubing serves as a reservoir for any liquid 
released from the receptacle. The drain shown in FIG. 15 is provided with 
a cap 124 provided ports 125 whereby to facilitate separation of the 
liquid of the body waste for flow into the tubing. Thus, the cap may be 
referred to as a strainer or separator. 
The seat 84 and cover 85 are designed and constructed substantially in 
accord with the seat 5 and cover 6 described above. 
In view of the foregoing and referring to FIG. 14, the support 81 is 
mounted within the confines of the housing upon the panel 90, the 
container 82 upon and substantially within the support 81 with its 
reinforcing members 105 and 106 engaging the upper edges of the support, 
and the receptacle 83 is mounted in the container so that its flange 110 
will overlie the upper edges of the container and its reinforcing members 
105 and 106. The flange may be adhesively or otherwise secured to the 
external surfaces of the reinforcing members 105 and 106. The flange may 
be adhesively or otherwise secured to the external surfaces of the 
reinforcing members 105 and 106. The seat has a lower tapered surfaces 126 
which serve to press the walls of the receptacle into intimate engagement 
with the inner surfaces of the walls of the container and under surfaces 
127 of the seat serve to press the flange 110 of the receptacle into 
sealing engagement with the upper edges of the walls of the container and 
upper edges of the reinforcing members affixed thereto. This unique 
arrangement serves to substantially prevent the escape of any odors and 
the release of odors is also substantially prevented due to the fact that 
a lower portion 128 of the cover substantially seals an opening 129 in the 
seat. Furthermore, the structure may be referred to as a self contained 
portable toilet assembly. The arrangement is also such that the 
receptacle, and tubing may be readily disposed of after use so that a new 
receptable and tubing and/or riser may be installed, or if so desired, a 
receptacle can be provided without a drain. 
As exemplified in FIG. 16, the structure of FIG. 14 may be readily modified 
or converted so that the liquid may be deposited at a remote sanitary 
location, such, as for example, in a sump 130. 
More particularly in this regard, the tubing is extended through an opening 
131 in the bottom wall 100 of the container 82 and through aligned 
openings 132 and 133 respectively provided in the support 81 and base 80 
and the free end of the tubing is opened for detachably receiving the 
upper end of a well point driven into the ground to constitute the sump 
130. Obviously, the sump may be in the form of a buried mass of gravel or 
stones. The opening 131 is provided by removing the portion 103 of the 
bottom wall 100, the opening 132 by removing the portions 97 of the end 
portions 93 of the support 81 and the opening 133 by bending the portion 
98 of the front wall 88 of the base 80 downwardly and outwardly as shown. 
It is to be understood that if the length of the tubing shown in FIG. 10 
is insufficient a longer length for the use in FIG. 16 may be provided. 
DESCRIPTION OF FIGS. 19-26 
A fourth toilet assembly or system embodying one or more inventions is 
exemplified in FIGS. 19 through 26 of the drawings, and is primarily 
directed to structure providing for a pair of receptacles, of which a 
lower one preferably has a larger capacity for body waste preferably in 
the amount of fifteen (15) gallons and the other or upper one has a lower 
capacity preferably in the amount of five (5) gallons may be utilized. 
More specifically, this fourth assembly comprises a base or housing 
generally designated 150, a support or enclosure generally designated 151, 
a lower relatively large receptacle 152 disposed in the support, a 
container generally designated 153 disposed in the large receptacle and 
having a smaller or upper receptacle generally designated 154 arranged 
therein, a seat generally designated 155 and a cover generally designated 
156. 
The base or housing 150 is constructed substantially the same as the bases 
or housings as described above and comprises a bottom wall 157, a pair of 
parallel side walls 158 reinforced by upper outer members 159 and a pair 
of end walls 160 reinforced by upper outer members 161. A panel 162 is 
provided for disposition on the bottom wall 157 to impart stability to the 
housing. 
The support or enclosure 151 is preferably constructed like the supports 
previously described, serves as a container for the large receptacle 152, 
and is made from a single sheet of material which is creased or scored so 
that it can be folded or manipulated to provide a pair of planar side 
walls 163, an end wall 164 and a pair of corresponding end portions 165 
forming an end wall parallel to the end wall 164. The lower extremities of 
the side walls are preferably provided with reinforcing members 166, the 
end wall 164 with a member 167 and the end portions 165 with spaced 
reinforcing members 168. 
The larger receptacle 152 in the support or enclosure 151 is preferably 
made from a suitable resiliently flexible plastic liquid proof material 
and substantially shaped like a bag having a bottom wall 169, opposed 
pairs of walls 170 and 171 and an outwardly extending peripheral flange 
172. 
The container 153 subtantially corresponds in design and construction to 
the container 82 as described above, and includes a bottom wall 173, a 
pair of side walls 174, and a pair of end walls 175. The upper extremities 
of these side and end walls are preferably reinforced by members 176 
adhesively or otherwise secured to the external surfaces of these walls. 
The samll receptacle 154 is preferably of a resiliently flexible liquid 
proof character and has a bottom wall 177, a pair of opposed side walls 
178, a pair of end walls 179 and an outwardly extending peripheral flange 
180. 
In the operative relationship of the components as illustrated in FIG. 22, 
the support 151 is mounted in the housing 150 upon the panel 162 so that 
the upper edges of the walls of the housing 150 support 151 and 
reinforcing members 161 affixed to the housing are substantially flush and 
the larger receptacle 152 is then preferably arranged in the support 151 
so that its flange 172 overlies the aforesaid upper edges and may be 
secured against the outer surfaces of the members 161 by an adhesive, if 
so desired, receptacle 154 therein as a unit. 
The container 153 and smaller receptacle 154 therein as a unit may next be 
mounted in the larger receptacle 152 and support 151 so that its outer 
upper reinforcing members 176 will primarily rest on the upper edges of 
the support 151 thereby assisting to hold the flange 172 of the large 
receptacle 152 in a sealed relationship between the support and container 
in order to alleviate the emanation of any odors from the larger 
receptacle. The flange 180 of the smaller receptacle is arranged to 
overlie the upper edges of the side and end walls of the container, 
including the upper edges of the members 176 affixed thereto and 
preferably depend along the outer surfaces of these members where they may 
be secured thereto in any mode desired. 
The seat 155 is substantially the same as the seat previously described and 
includes a lower surface 181 which engages the flange 180 to firmly hold 
it in place. This seat also has lower external tapered surfaces 182 which 
serve to press the upper extremities of the walls of the smaller 
receptacle 154 against the inner upper surfaces of the walls of the 
container whereby to substantially seal the seat to the container for the 
purpose of preventing the release of odors from the smaller receptacle and 
release is also substantially prevented due to the substantially sealed 
connection between a lower portion 183 of the cover and an opening 184 in 
the seat, all of which has been alluded to above. 
The receptacles 152 and 154 are respectively provided with drains and/or 
means for separating liquid of the human body waste and they substantially 
correspond in design and construction to those described above. More 
specifically, a drain provided for the larger or lower receptacle 152 
comprises a fitting 185 sealably connected to the bottom wall 169 of the 
receptacle and this fitting is readily detachably connectible with a 
fitting 186 detachably connected to a length of tubing 187 which is coiled 
or arranged betwen the bottom wall 169 of the receptacle and the platen 
162. The free end of the tubing is closed so this tubing may be considered 
to constitute a reservoir. The drain may also include a riser 188 through 
which the tubing extends for elevating the drain so that ports 189 in a 
cap 190 enclosing a raised portion 191 of the bottom wall of the 
receptacle are located at a level whereby liquid may flow through the 
ports into the tubing. Obviously, risers of different heights may be 
employed. 
The drain for the smaller or upper receptacle 154 also comprises a pair of 
detachably connectible fittings 192 and 193 respectively detachably 
connected to the receptacle 154 and a length of tubing 194, a riser 195 
and a cap 196 provided with ports 197 through which liquid may flow into 
the tubing for storage. This drain and the one employed for the receptacle 
152 is clearly exemplified in FIG. 23. 
The provision of the structure just described embodying a pair of 
receptacles with one disposed substantially within the confines of the 
other provides a unique organization whereby one or the other may be 
utilized to receive human body waste. More particularly in this regard, 
the container 153 and smaller receptacle 154 may be utilized first to the 
extent desired, in which event, the receptacle and contents may be removed 
and transported to a sanitary location, so that the larger receptacle can 
be utilized to an extent described and removal for deposit at a remote 
location. If so desired, the container and receptacle as a unit may be 
initially removed, in which event, the large receptacle can be utilized 
first and the unit subsequently. Otherwise expressed, the assemblies 
provide for a pair of substantially self contained units adapted for 
successive use. 
The structure described in the preceding paragraph also offers the 
advantage that it may be modified or converted as exemplified in FIGS. 24 
and 25, so that, if so desired, the liquid in the upper receptacle 154 may 
be caused to flow through its tubing 194 into the lower receptacle 152 and 
the liquid in the lower receptacle may be caused to flow through its 
tubing 187 into a sump 198 at a remote sanitary location. The tubing 194 
may obviously be cut to any desired length, such as shown in FIG. 24. This 
tubing is extended through an opening 199 formed by bending a portion 200 
of the bottom wall of the container downwardly. The tubing 187 is extended 
through an opening 201 formed by removing detachable portions 202 of the 
end portions 165 of the support and through an opening 203 by bending a 
portion 204 of an end wall of the housing outwardly as shown. The sump 
198, alluded to above, may be in the form of a well point which is 
detachably connected to the tubing in any conventional manner. 
The structure of FIG. 24 may be converted or modified as depicted in FIG. 
26 by bending outwardly a portion 205 of an end wall of the container 153 
so that the tubing 194 can be extended outwardly through an opening 206 
provided by the bending of the portion 205. Otherwise expressed, the 
container 153 and receptacle 154 therein, including a seat and cover as a 
complete assembly or unit may be utilized separately at a desired location 
to the exclusion of the other components shown in FIG. 24. Also, if so 
desired, the container 153 as shown in FIG. 26 could be utilized with the 
other structure of FIG. 22, provided adjacent end walls of the housing and 
support are provided with aligned openings through which the tubing 194 
could be extended in lieu of having it release liquid into the lower 
receptacle 152 as shown in FIG. 24. 
Having thus described my invention or inventions, it is obvious that 
various modifications or additions to those described may be made in the 
same without departing from the spirit of the invention and, therefore, I 
do not wish to be understood as limiting myself to the exact forms, 
constructions, arrangements, and combinations of the components herein 
shown and described.
