     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to toilet seat assemblies that will conveniently accommodate an adult, a child, or a pet. 
     2. Description of the Related Art 
     U.S. Pat. No. 1,189,767 discloses a series of nested toilet seats having different sized openings therethrough positioned above a toilet bowl such that individuals may each select the toilet seat to be used by such individual and with toilet seats having smaller openings than found in the selected seat being moved out of position by the user. 
     U.S. Pat. No. 4,461,046 discloses a family toilet seat assembly to be positioned on a toilet and having a first adult toilet seat with a large opening for use by adults, and with the large opening having a surrounding lip that extends downwardly into the toilet bowl and a second child toilet seat having a smaller opening with a lip extending downwardly into the opening of the adult seat and a cover fitting within and spanning the opening of the child toilet seat. 
     U.S. Pat. No. Des. 309,176 discloses a combination adult and child seat and cover wherein an adult seat has a large opening into a toilet, a child seat fits entirely over the adult seat and has a smaller hole therethrough and a cover fits over both the child seat and the adult seat. 
     U.S. Pat. No. Des. 356,635 discloses a combination adult and child toilet seat and cover wherein a cover fits on and rests on a child toilet seat, which, in turn, rests on an adult toilet seat. The child and adult toilet seats and the cover appear to have the same peripheral dimensions. 
     The Internet at EveryBody Potty.com shows a seat assembly having an adult toilet seat and a child toilet seat pivoted to a common hinge and with the child toilet seat arranged to rest on the sides of the top surface of the adult toilet seat. The usual toilet seat cover is also hinged to the common hinge and has an undersurface recessed to fit over the child toilet seat when the cover is closed. 
     SUMMARY OF THE INVENTION 
     The invention includes a conventional adult toilet seat having a standard hole therethrough and with the wall of the hole beveled inwardly from the top surface of the seat to the bottom surface thereof. A child toilet seat is hinged to pivot between a raised up position and a lowered position overlying the adult seat. The child toilet seat has a hole therethrough that is aligned with the hole through the adult toilet seat but that is smaller than the standard hole. A cover fits within the smaller hole and has a peripheral edge that is beveled to conform to the beveled edge of the smaller hole. In this fashion, the child toilet seat and cover cooperate to cover the adult toilet seat. 
     An optional animal waste receiving receptacle is mounted to be positioned between the beveled edge of the cover and to engage the beveled edge of the smaller hole. Air passage is provided through the seat assembly between the adult and child toilet seats that are spaced apart by stops carried beneath the child toilet seat and into a toilet bowl of a toilet on which the adult and child toilet seat assembly is mounted. 
     The cover is hinged to pivot between an upright position and a lowered position fitting into the smaller hole, with the cover forming a continuation of the seating surface of the child toilet seat. A support arm is pivotally connected to the cover and to the child toilet seat to provide a brace for the cover when the cover is raised. In such an optional embodiment, the cover in the raised position may act as a seat back for a child sitting on the child toilet seat. 
     The child toilet seat may optionally include a removable combination footrest/step attached thereto to provide a footrest for a child sitting on the child toilet seat and to facilitate a child climbing onto the toilet to sit on the child toilet seat when the child acquires the physical skills necessary for climbing onto the child toilet seat. 
     The child seat also may optionally include a removable receptacle to receive disposable splash deflectors that will attach to the front edge of the surrounding rim of the hole through the child seat and that will serve to deflect a fluid stream from a boy sitting on the child seat into the toilet on which the toilet seat assembly is mounted. 
     An optional pet waste receiving receptacle is hinged on the same hinge pin as the child seat and is positioned between the beveled edge surrounding the hole through the child seat and the beveled edge of the cover. The receptacle has a peripheral wall that is slanted inwardly from a top edge to a bottom edge so that the receptacle will rest on the beveled edge of the smaller hole through the child toilet seat and will snugly receive the inclined peripheral edge of the cover. An optional disposable liner is provided to fit into the receptacle and will be positioned over the toilet bowl when the receptacle is separated from the raised cover and is lowered into position resting on the beveled edge of the hole through the child toilet seat. Optionally, the liner will have an adhesive material around at least a portion of the outer rim thereof to be releasably secured to the peripheral edge of the hole through the child toilet seat. A dispenser for holding a supply of the disposable liners is releasably attached to the bottom of the adult toilet seat. 
     In use, the adult toilet seat, child toilet seat, cover, and, if provided, an optional animal waste receptacle, are all pivoted to proximate the toilet bowl. Access to the interior of the toilet bowl can then be accomplished merely by raising the adult toilet seat together with the child toilet seat, cover, and optional animal waste receptacle. The adult toilet seat can be made ready for use merely by pivoting the child toilet seat to its fully raised position. The adult toilet seat is then ready for use. 
     The child toilet seat can be made ready for use by leaving the child toilet seat in its fully lowered position and raising the cover and the optional animal waste receptacle that is frictionally secured to the cover, if provided. Thereafter, the optional animal waste receptacle can be separated from the cover and then be fully lowered into engagement with the peripheral edge of the child toilet seat. An optional disposable liner, that is made of material that will entice the animal is placed in the optional animal waste receptacle and the seat assembly is ready for use by a pet, such as a cat. After use by the animal and/or depending upon the needs of adults and children the used disposable liner is removed from attachment to the child toilet seat and is dropped into the toilet bowl to soak and disintegrate so that the toilet may be safely flushed.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the drawings: 
     In the illustrated optional embodiment of the invention the multi-use toilet seat assembly is shown generally at  10 . The assembly  10  includes an adult toilet seat  12 , a child toilet seat  14 , an optional animal waste receptacle  16  and a cover  18 . 
     The adult toilet seat  12  is of generally standard construction for toilet seats and is shaped to fit over the open top of a toilet, not shown. A hinge pin  19  is secured to a rear portion of the adult toilet seat  12  and is adapted to be secured to a toilet in conventional fashion. A hole  20  is provided through the adult toilet seat  12 , with a peripheral wall  22  surrounding the hole. The peripheral wall  22  is beveled inwardly from the top of the adult toilet seat  12  to the bottom of the adult toilet seat. 
     The child toilet seat  14  is hinged on the same hinge pin  19  as the adult toilet seat  12  and the child toilet seat  14  can be pivoted between a lowered position resting on the adult toilet seat  12  and a fully raised position. In the fully lowered position of the child toilet seat  14  the seat is in position to be used by a child and it is only necessary that the optional animal waste receptacle  16 , if provided, and the cover  18  be removed from the hole  26 , which is smaller than the hole  20 , before such use can occur. 
     It is contemplated that the cover  18  may be hinged to the same hinge pin  19  as the adult toilet seat  12  and the child toilet seat  14  as shown in FIGS. 9 and 10. Alternatively, as shown in FIGS. 1-5, the optional animal waste receptacle and the cover  18  are hinged to a separate hinge pin  30 , secured to the child toilet seat  14 , between the hole  26  and a rear edge  32  of the child toilet seat  14 . 
     Referring generally to FIGS. 1-8, as previously discussed, an optional animal waste receptacle  16  may be provided. In an optional embodiment in which the optional animal waste receptacle is provided, the animal waste receptacle  16  has a bottom  34 , and a flared surrounding wall  36  that will fit into and close the hole  26 . The top of the animal waste receptacle  16  is open to snugly receive the cover  18  as a plug when the cover is in its lowermost position and when the cover  18  is pivoted to its fully raised position the animal waste receptacle is raised to its fully raised position along with the cover  18  to which the animal waste receptacle is frictionally engaged. When the cover is separated from the animal waste receptacle and is raised the receptacle remains positioned in the hole  26  and will receive a disposable liner  38  (FIG.  3 ). The disposable liner  38  may be made of a suitable paper or litter material or a combination thereof that will receive urine and feces from an animal and that will clump and absorb the liquid content of such animal waste while retaining its shape fitting into the animal waste receptacle  16 . Periodically, and before use of the adult toilet seat  14  or the child toilet seat  18  the disposable liner  38  and its contents are removed from the animal waste receptacle and are discarded into the toilet bowl if the liner will subsequently dissolve before flushing, or into another trash receiving container, not shown. 
     Referring again to the cover  18 , a brace  40  has one end  42  pivotally attached at  44  to the top of cover  18  and the opposite end of the brace pivotally attached at end  46  of the brace to a pin  48  that slides in slots  50  provided in sidewalls of a groove  52  formed in the top surface of the child toilet seat  14  at a location between the hinge pins  19  and  30 . When the cover  18  is raised pin  48  slides rearwardly to engage end  54  of the groove  52 . The cover  18  then forms a support to prevent further tipping of the cover and allows the cover to serve as a supported back rest for a child sitting on the child seat. The hinge pins  19  and  30 , the telescoping brace  40  and the pivot connections  44  and  46  are all optionally recessed into the child toilet seat  14  and the cover  18  when the child toilet seat and the cover are in their lowered positions, as shown in FIG.  1  and FIG.  2 . 
     An optional step/footrest  50  is suspended from the bottom front of the adult toilet seat. A pair of receiver openings  52  and  54  are provided at opposite sides of the adult toilet seat  12 . The step  50  is curved along a front edge  56  so that it will extend around the front edge of a toilet upon which the multi-use toilet seat assembly is attached. Hangars  58  and  60  are provided at opposite ends of the step  50  and are made sufficiently flexible to provide for positioning of the step. Hangar  58  is angled to have a flat finger  62  that extends into the receiver opening  52  and hangar  54  has a slot  62 ′ therethrough so that a flat finger  64  is inserted through and is wedged into the receiver opening  54  to secure the step/footrest to the adult toilet seat  12 . 
     When not in use as a step for a child or an animal such as a cat or as a foot rest for a child the step  50  may be removed by withdrawing the flat finger  64  and then sliding the flat finger  62  from receiver opening  52 . 
     Additional receiver opening slots  66  and  68  may optionally be provided at opposite sides of the bottom of the adult toilet seat. Optional containers  70  and  72  respectively have flat fingers  74  and  76  that extend into the receiver opening slots  66  and  68  to secure the containers to the bottom sides of the adult toilet seat. The optional containers  70  and  72  can hold optional disposable deflectors  78  to be attached to the front of the hole through the child toilet seat and optional disposable liners  38  positioned in and adhesively attached to the interior of the animal waste receptacle. The disposable deflectors  78  are curved to conform to and to be adhesively bonded to the front edge of the hole  26  through the child toilet seat  16  and to extend upwardly to above the top of the seat and downwardly to below the bottom of the seat when a boy child is using the child toilet seat  14 . When the boy is finished and is removed from the seat the disposable deflector is removed from attachment to the edge of the hole and is dropped into the toilet bowl to disintegrate and to be flushed away.
