• Claim. (Cl. 4-10) My invention relates to a new and improved device for washing bed-pans and urinals.
• I provide a combination washing device and toilet bowl which can be made and installed at minimum expense.
• the combined device does not require more floor space than the conventional toilet bowl.
• the improved combination device requires only a minor addition to the conventional plumbing, which is an important feature, in order to make it possible to make and install the device at minimum expense and without increasing the size of the toilet room.
• Fig. 1 is a front perspective view of the first embodiment. The door of the washing hopper or casing is shown in closed position.
• Fig. 2 is a vertical longitudinal central section of Fig. 1, showing a urinal in washing position and releas ably held at the inner face of the closed door.
• This embodiment shows a toilet bowl which has an S-trap said bowl being modified according to my invention.
• Fig. 3 is a vertical longitudinal central section of a second embodiment, showing a bed-pan in washing position, and releasably held at the inner face of the closed door.
• This embodiment shows a toilet bowl which has a P-trap, said bowl being modified according to my invention.
• Figs. 1 and 2 This has a toilet bowl 10, whose pedestal 11 is supported on floor 12. Bowl has a rim 21. A seat S is turnably connected to bowl 10 by hinge H. This hinge H may be connected to any part of the device.
• Bowl 10 has a basin B, which has a rear overflow wall 16.
• the basin B normally has a pool of water, which has a normal top level 21a.
• the ordinary toilet bowl has a top seat opening, and an imperforate top wall which is located at the rear of said top seat opening and at the rear of the seat.
• the ordinary toilet bowl is of the S-trap type, it has a single lateral partition wall 31 which is integral with the rim and side walls of the bowl. The horizontal bottom edge of this ordinary single S-trap wall 31 is located below the horizontal level plane which is indicated by the reference numeral 21a.
• I provide an additional hopper opening in the top wall of the bowl rearwardly of the usual top seat opening of the bowl, and I provide the bowl with an additional integral lateral partition wall 19, whose horizontal bottom edge is also located below the plane 21a.
• This partition wall 19 is located rearwardly of the S-trap wall 31.
• I thus provide said additional top washing opening of the bowl with a passage or conduit 22, which is open at its top and bottom, and which is closed at its sides by the side walls of the bowl.
• the supplemental partition wall 19 is located forwardly of the rear wall 16 of basin B. This supplemental partition wall of trap wall 19 extends below the outlet passage or conduit 17, and below the top of the basin part B and hence below the top of the normal pool of Water in said basin part B.
• This supplemental trap wall 19 prevents dangerous sewer gases from backing up into the room through conduit 22 and through the hopper 23 which is to be described shortly.
• the passages or conduits 17 and 17a provide a siphon outlet to the waste.
• the washing hopper 23 is held fixed relative to bowl 10.
• Said hopper 23 has a bottom flange 24 which is fixed to the top wall of the bowl at its supplemental top opening, in order to provide a sealing connection between the interior of hopper 23 and the passage or conduit 22.
• a sealing gasket or other sealing means may be used, in order to provide a liquid-tight and airtight connection between the interior space of hopper 23 and the top wall of the bowl at the top of passage 22.
• hopper 23 One optional shape of hopper 23 is shown in Fig. 2.
• a door 33 is turnably connected to lugs 32 of the front wall 28 of hopper 23 by a shaft 34 which is turnably mounted in said lugs 32.
• Said door 33 optionally has a stop extension 33a which abuts the inner face of the front wall 28, when door 33 is closed.
• Door 33 may have a conventional sealing gasket and it may optionally be biased to normal closed position by a spring.
• a vent-pipe 29 is optionally provided in the top wall 27 of hopper 23.
• Conventional means are shown for releasably holding the bed-pan or urinal to door 33.
• Laterally spaced arms 42 are fixed to the inner face of door 33, and additional laterally spaced arms 40 are also thus fixed. These arms 42 and 40 are perpendicular to the planar door 33. Arms 42 are provided with lateral fingers 43 which extend laterally towards each other, and arms 40 are provided with similar fingers 41.
• Arms 42 are longer than arms 40. p
• the lateral spacing between arms 42 is less than the lateral spacing between arms 40.
• a bed-pan 45 can thus be supported in upstanding position when door 33 is closed, as shown in Fig. 3.
• the urinal 46 has a hook by means of which said urinal 46 may *be supported in inverted upstanding position when door 33 is closed.
• Door 33 may be opened to horizontal position, and the urinal or bed-pan can then be mounted upon door 33. The door 33 is then closed, in order to empty the contents of the receptacle into hopper 23 and through passage 22 into the bowl.
• the door 33 can be opened by depressing the pedal 37 of a lever 35 which is pivoted at 36 to bowl 10.
• the cylinder 39 of a conventional dash-pot is pivoted at 39a to lever 35.
• the piston of cylinder 39 has a piston rod 39b which is pivoted at 39c to an arm 38 which is fixed rigidly to turnable shaft 34.
• pedal 37 When pedal 37 is depressed below its normal position, the air or liquid in cylinder 39 is subjected to pressure, thus moving rod 3% upwardly, and turning door 33 to its open position.
• Lever 35 may be biased to a normal position, in which door 33 is closed.
• Fig. 1 shows a water-supply pipe 50. This is connected to branch or extension pipe 51 through an ordinary and normally closed flushing valve V. Said flushing valve V may be opened by manually operating the usual handle 53.
• Pipe 51 is connected to flushing pipe 51a and to washing pipe 52, through a conventional two-way valve VA.
• This two-way valve VA can be operated by handle 54 to a washing position in which flushing pipe 51a is blocked from pipe 51 and washing pipe 52 is connected to pipe 51.
• This two-way valve VA can be turned to another position which is the flushing position, in which washing pipe 52 is blocked from pipe 51, and pipe 51a is connected to pipe 51.
• the outlet of the flushing pipe 510 is connected to bowl 10, in order to supply flushing water to bowl when valve V is opened and the valve VA is in the flushing position.
• the washing pipe 52 is connected to any selected number of washing nozzles which are provided in the interior of the washing hopper 23. These washing nozzles may be spray nozzles or of any type. Two washing nozzles 55 and 56 are shown as illustrations.
• valve VA When it is desired to wash the receptacle, the door 33 is closed, thus emptying the receptacle by means of the bottom opening of hopper 23 and passage 22. Valve VA is turned to the washing position. Valve V is then opened, thus supplying water to the washing nozzles, without supplying flushing water to the bowl through pipe 51a.
• washing nozzles there are enough washing nozzles to thoroughly wash the interior and exterior of the receptacle and the inner wallsof the hopper 23 and door 33.
• the wash water flows through passage 22 into basin B and said basin is emptied by the usual siphon action.
• the pipe 50 may be connected to supply cold water. Hot water or sterilizing steam may be admitted to the hopper 23 through conduits 51 and 52 through a by-pass valve.
• vent pipe 29 may be omitted.
• top wall 27 of hopper 23 is imperforate.
• the pedal device may be omitted, and the door 33 may be opened and closed by hand.
• the door 33 is optionally inclined rearwardly when it is closed, so that gravity can normally hold door 33 in closed position.
• the bowl 10 has a modified P-trap construction.
• This bowl has an outlet passage or conduit 58a.
• the ordinary P-trap bowl has a single lateral partition wall 57.
• I provide the bowl 100: with an additional integral lateral partition wall 58 at the rear of the supplemental opening at the top of the bowl, thus providing a passage 22a which has the same function as passage 22, and which similarly prevents dangerous sewer gas from entering the room through hopper 23.
• thewall 58 functions as the trap wall.
• the trap is an internal part of the bowl.
• the hopper is connected to a supplemental inlet opening of the combination bowl and trap device, and said supplemental inlet opening is located rearwardly of the main top inlet opening of the bowl.
