The invention provi-des a complete folding toilet unit having substantial advantages for use in many installations where it is desired to conserve space, typical examples being railroad cars, airplanes, and other vehicles as well as in business or living quarters where floor space is limited. The unit includes both a hopper and a lavatory each mounted in a common frame for movement between an open position ready for use and a closed position wherein it is folded into the frame and occupies minimum space. To add to the visual lappearance of the unit, panels are provid-ed covering the spaces above and below the hopper, these panels being so mounted in the frame as to move into and out of their desired covering positions in -response to the movement of the hopper between its open and closed positions `and to impart a smooth and substantially unbroken lappearance to the unit when the hopper is closed, facilitating the keeping of the entire unit in a clean and sanitary condition.

An operating member such as a foot treadle is provided for flushing of the hopper, and it is so constructed Iand arranged that when the hopper is closed, it -retracts from its advanced convenient oper-ating position to a position within the frame wherein it is substantially inaccessible and out of the way. In addition, the operating connection between this treadle and the iiushing system is such that the treadle can operate to initiate nushing of the hopper only when it is in its advanced position, thus effectively preventing accidental flushing of the hopper When it is n-ot fully lowered to its operative position.

The iiushing system also includes a valve such as a iiapper valve for controlling the discharge outlet of the hopper, and this valve is so connected with the flushing mechanism that it opens in response to actuation of the flushing mecha- `nism but remains closed at other times to prevent th-e passage to and from the hopper of air currents such as may be caused by motion of a train or other vehicle wherein the unit is installed.

Provison is made in accordance with the invention for power operation of the hopper in moving between its open and closed positions. Thus the hopper can be caused to open or close by simple manipulation of a button, valve or other control member. Highly satisfactory results have been obtained by the use of hydraulic operating means for the hopper such as one or more doubleacting hydraulic cylinders. Since the toilet unit normally includes connections to a water supply for iiushing and for the lavatory, it is a simple matter to make the proper connections for supplying water to operate the hopper cylinders. In addition, the cylinders may be connected with the flushing system in such manner that when pressure is applied to one side of the cylinder or cylinders to cause the hopper to open, the waste water from the opposite side of each cylinder is caused to flow into the hopper to provide a wet bowl preparatory to use.

The invention also provides in the toilet unit a m-irror mou'nted in the frame above the lavatory and equipped with built-in light sources arranged to give highly effective illumination for Ithe face of the user while at the same time shielding the users eyes from direct glare. It has been determined that when a person is looking substantially straight ahead, the angular range of vision of the eyes is substantially greater in a horizontal plane than in a vertical plane. That -is to say, even though the eyes are directed straight ahead, they will still be able to perceive objects `to the right or left over a substantial angular range, but the corresponding range of perception with lrespect to objects above or below the direct line of level vision is considerably more restricted. In accordance with the invention, the light sources for the mirror are mounted only above and below the mirror and in predetermined positions forwardly of the plane thereof such that they will lie respectively above and below the range of level vision of the user `oiF-the mirror both as viewed directly-and by reflection in the mirror. This arrangement is practicable even though the light sources would lie within the horizontal range of the users vision if they were positioned at the same distance apart at either side of the mirror. In addition, these light sour-ces are provided 'with means for directing thelight therefrom forwardly of the mirror and respectively downwardly and upwardlyat such angles to the horiaontal as to produce effective 'illumination on the faceof the user without striking the users eyes in such manner as to cause glare.

Referring to the. drawings, which illustrate preferred embodiments of the present invention, `Figs. 1 and 2 show a complete folding toilet unit comprising a frame which'is indicated generally at and includes a pair of front channel bars 26 and a pair of rear channel bars 2l, these channels being integral or secured together as indicated by the front and rear angle bars 2B and side angle bars 29 at the bottom of the frame. In the frame 25 are mounted a lavatory 3Q, a

hopper indicated generally at 33, and a mirror 55 positioned above the lavatory and provided with upper and lower light sources indicated generally at and 3l, respectively. Fig. l shows the unit with both the lavatory and hopper in their closed positions, in which they fold into the frame and into substantially vertical positions occupying minimum space horizontally. Fig. 2 shows in full lines the positions of the hopper and lavatory when open, in which positions they extend substantially horizontally fromthe frame, and also shows in dotted lines the positionsof the lavatory and hopper when closed as illustrated in Fig. 1.

The construction and operation of the lavatory is shown in somewhat more detail in Figs. 2 and 6. Referring to Fig; 2, the lavatoryis :mounted for swinging movement about a horizontal pivotal mounting 5D in the frame, and it extends rearwardly at M beyond this pivotal mounting and under a faucet fixture 52, one of the operating levers for this fixture being shown at 43. Stop means such as one or more rubber'buttons or bumpers 44 are positioned on' the underside of the fixture 52 to engage the lavatory portion il and thus to stop thelavatory in the desired horizontal position as shown in Fig. 2. Another stop, shown as a cushion l5 or" rubber or like material, is mounted in the frame as shown in Figs. 1 and 2 to engage the front rim of the lavatory when it is closed. Releasable latches 46 are provided at each side of the lavatory and are adapted to engage within the frame to hold the lavatory in closed position, and a handle it? is provided for controlling these latches as described in detail in connection with Figs. 19 and 2-0. When the lavatory is closed, as shown in Figs. 1 and 5, its bottom will be substantially flush with the panel 48 xed across the front of the unit frame.

The piping for conveying water to and from the lavatory is shown in Figs. 2, 5 and 6. Connections for hot and cold water for the faucet xture 42 are indicated at i9 and '55, respectively. in Figs. 2 and 5, and it will be understood that they provide for connections to the regular water supply of a railroad car or other vehicle or building in which the unit is installed.

A tank 5I open at the top thereof is mounted in the frame 25 as shown in Fig. 2 in such manner that the back portion di o the lavatory enters 6 therein when the lavatory is closed, thus dumping into this tank 5| any water that is in the lavatory.

From the tank 5I, the water passes through pipev 52 to a trap coupling 53 (Fig. 6) from which it is conducted lthrough a connecting pipe 5d to the main drain or sewer pipe of the unit. The trap coupling 53 is provided with a removable plug 51 for clean-out purposes, and also vwith a supplemental connecting line 52 (Fig. 6) to the main drain, this line being controlled by a petcock 59 and providing for draining liquid from the trap 53 before removal of plug 5l for cleanout purposes. It should also be noted that the unit may be constructed without the mirror, in which case the top of the frame 25 is iinished over above the lavatory as shown at Se in Fig. 5.

The general construction of the hopper is best seen in Figs. l to 8 and 12 to 14, and as shown, it includes a bowl having a relatively flat bottom portion E5 and upwardly curved side portions 65. The bowl bottom slopes upwardly from front to back when the hopper is open, as illustrated particularly in Figs. 12 and 14, 'and a discharge outlet t7 is formed at the back of the bowl. As shown in Figs. 13 and 14, a bracket frame 58 extends across the back of hopper bowl and 'is welded or otherwise secured thereto. A curved connecting pipe 'l leads from the discharge outlet (il and telescopes into the main drain pipe 55 to provide for the necessary movement of the hopper relative to pipe 55when opening and closing. Y As shown in Fig. ll, the pipe li) is hanged and bolted to the bracket frame 58 at i, a suitable gasket 12 being provided to insure a tight connection. f

The top of the hopper bowl is formed by an annular tray l5, which is welded `or otherwise secured to the bowl as indicated at 76 (Fig. 3). This tray includes a downwardly extending outer iiange portion 'il surrounding the front and sides of the bowl as shown in Figs. l and 12 and an upwardly inclined rear edge '18. A seat 8G is provided with a, hinged connection 8i to the back of the tray l5 for swinging movement as shown in Fig. 5, and this seat is also `provided with rubber bumper members 82 adapted to support the seat on hopper tray 1'5. The lower part of the bowl is enclosed by a skirt 85 shaped somewhat like a scoop which conceals the bowl and the flushing connection thereto.

The skirt 85 engages under the flanged portion Tl of tray l5 and may be bolted or otherwise removably secured thereto as indicated at 85 (Fig. 6) and provides a nished appearance to the unit when the hopper is closed, as illustrated in Fig. 1. A panel 88 is hingedly connected at 83 along the lower edge of skirt 85 to cover the space below the skirt when the hopper is closed. As shown in Figs. 2 and 4, this panel folds upwardly and retracts with the skirt when the hopper is open, but it advances when the hopper is closed to overhang the space below the skirt, in which position it combines with a panel 50 bolted or otherwise secured to the front pair of channel bars 26 of the frame,v thusproviding a smooth and finished appearance for the unit as shown in Fig. i.k Additional side panels 92 may be provided at the sides of the frame as shown in Fig. 1 to enclose the operating parts of the unit.

The structure for supporting the hopper in frame 25 is best seen in Figs. 8, 5 and 6, and it includes a pair of brackets 99 each of which is welded at Il!!! or otherwise secured to the hopper bowl and also to the bracket frame 58 at the back of the bowl. Each bracket S5 is provided with a. bearing (Fig. 3) in which is journaled a stud or trunnion |02. Ea-ch-stud |02 is mounted in a bearing |03 (Fig. 6) whichis bolted between a pair of plates |04 which 'brace the corners of the frame 25,. The brackets 98 are also provided with a brace |05 extending across the bottom of the bowl and preferably Awelded thereto at |06 for additional stiffening eiect. This brace is adapted to engage a stop |01 (Fig. 3) at the front of the frame when rthe hopper is fully open, thus limiting opening movement of the hopper.

The flushing system for the hopper is best kshown in Figs. 8, 12, 13, and 2l. Referring particularly to Figs. 12 and 15, a fixture ||0 is welded at |00 to the bottom of the hopper bowl `and provided with a connecting pipe leading to a suitable supply of water under pressure for flushing. An angular plate ||2 Vis welded at 3 along one edge to the xture |10, and its opposite end extends through a slot ||4 inthe side of the hopper bowl and is welded to the bowl as at ||5. As shown Ain Fig. 15V, this plate |,2 thus combines with the .bottom of xture |,|0 to form a narrow passage or jet ||6 leading from the interior of -the fixture 0 through slot ||4 into the bowl and extending substantially across the flat bottom portion v65 ofthe bowl as Vshown in Fig. 13.

The `jet opening ||6 from xture A| I0 provides for admitting to kthehopper bowl a maior proportion of the .flushing liquid supplied to the xture 0, and vin addition a shower ring is provided for `admitting at the top of the bowl a minor proportion of the ushing liquid. Referring to Figs. 8, 12, 13 and 21, the shower ring is composed of two sections of pipe curved to fit within the upper part kof the bowl under tray 15 and having spaced outlets |2|. Each of these pipes 20 is provided with a coupling |22 which extends through a hole in the side of the vbowl for connection with an additional pipe |23 connecting at |24 with the sides of the jet fixture ||0. With this construction, either of the shower ring pipes |20 can be quickly and easily removed for repair or replacement by simply loosening the coupling |22 and withdrawing the pipe from the bowl, without the necessity of disconnecting or removing any other part of the hopper such as would be required if the shower ring were formed by a single curved pipe.

It will accordingly be seen that when water is supplied under pressure to the fixture |0 through pipe the major proportion thereof will be directed through the jet passage ||6 in a broad but relatively flat jet directed across the hopper bottom in such manner as to .sweep the contents of the hopper towards the discharge outlet 61. At the same time, a minor proportion of the water will be introduced as a shower at the top of the hopper to wash down the sides of the bowl into the path of the main jet, thus providing for highly effective flushing. Water for flushing purposes is preferably initially supplied through a direct pipe connection |25 (Figs. 5, 6 and 21) from the main cold water supply, and a connection |26 is provided from this pipe to a normally closed iiushing valve |21. A pipe |28 leads from the valve |21 to a vacuum breaker |29 of conventional construction, and a further pipe |30 leads from the vacuum breaker and connects with the pipe through a swiveled coupling |3 this swiveled coupling being provided to allow for swinging movement of the hopper relative to the pipe |30 during opening or closing movement of the hopper. It will be noted that the pipe 8 |25 is adapted to extend completely through the unit frame, thus providing for connecting a v series of units to a common water supply.

The invention provides for power operation .of the opening and closing movement of the hopper, and the drawings show double-acting hydraulic cylinders for leffecting and controlling this movement. Referring particularly to Figs. 2, 5 and 6, two double-acting hydraulic cylinders A|||0 are pivotally connected at |4| to the angle iron v28 extending across the back of the unit between the rear pair o f channnel bars 21 of vframe 25. The piston rods |45 from cylinders |40 are pivotally connected at |46 to the bracket frame 68 at the back of the hopper bowl. It will vbe seen that -with this construction, when pressure -iiuid is admitted to the lower sides of the cylinders 40, the pistons therein will be 4forced upwardlyand will accordingly cause opening'movement ofthe h0ppper,'the pivotal mountingsof ,the cylinders `|40 providing .for the necessary ;swinging `movement of the cylinders to follow the similar movement of the hopper. Conversely, when pressure fluid is admitted to the upper side of the cylinders |40, their pistons will be forced downwardly and will accordingly act to raise the hopper into its substantially vertical closed position.

The fluid for operating hydraulic cylinders |40 is supplied through a vbranch connection from the cold water line to the lavatory faucet, and additional connections are provided for conducting waste -water discharged from the cylinders |40 to the hopper bowl to provide a preliminary flush or wet bowl when the hopper is first opened. Referring particularly to Figs. 6 and 21, a-pipe |49 leads from the cold water side of the faucet fixture 42 to a four-way valve indicated generally at |50 and provided with a pair of control members such vas push buttons |5| and |52. From the valve |50, one pipe |55 leads to a ilexible hose |56 connecting through coupling |51 with a pipe |58 leading to the upper sides of the two cylinders |40, the flexible hose |50 being provided to allow for the movement of pipe |58 when the cylinders |40 swing as described. Another pipe |60 leads through a flexible hose |6| and coupling |62 to a pipe |63 connecting with the lower sides of the two cylinders |40. The fourth pipe |65 which leads from valve |50 connects at |66 with the pipe 28 which connects the flushing valve |21 with the vacuum breaker |29.

The valve |50 is shown as mounted in the front panel 41 ofthe frame, and the two control buttons |5| and |52 are preferably provided with suitable legends such as Open and Close as shown in Figs. 3 and 4. The arrangement within the valve is such that when the Open button |5| is actuatedit will connect the pipe |49 with the pipe |60 and simultaneously connect the pipe |55 with the pipe |65. When this occurs, it will be seen thatI line pressure from the cold water line 50 is applied at the lower sides of the cylinders |40, to force the pistons therein to rise and to cause the hopper to open; At the same time, since the upper sides of the cylinders will be connected through pipes |55 and |65 to the flushing line |28, this will cause the waste water displaced from the upper sides of the cylinders to be conducted through the vacuum breaker and through pipe |30, coupling |3| and pipe into the jet fixture ||0 .and thence into the bowl. This will thus provide the desired relatively small quantity of water to form a wet bowl in the open hopper preparatory to use. l

When the Close button |52 of valve |50 is actuated, the converse operation will take place. Line pressure Will be applied through pipes |49 and |55 to the upper sides of the cylinders |40, thus forcing the pistons therein downwardly to cause closing movement, of the hopper. During this movement, the waste water from the lower sides of the cylinders will be similarly conducted to the flushing line and thence into the bowl, and from there it will drain downwardly to the main drain pipes as a result of the vertical position of the bowl when closed. It should also be noted that if the hopper is reused before closing and reopening, the desired quantity of water for the preliminary ush will be left over from the flushing operation as a result of the upwardly sloping construction of the bottom portion 55 of the bowl, as shown in Figs. 12'and 14, which will prevent all the flushing water from draining from the bowl. In order to insure that this Water be perfectly clean, it is merely necessary to continue the flushing until the force of thejet has effectively cleaned the hopper. It will also be seen that when the hopper is finally closed, all water remaining therein will drain'through the outlet 51 to leave the bowl dry.

In addition to the movable panel 88 below thev hopper, other panels are mounted in the frame 25 for movement in response to opening and closing movement of the hopper between retracted positions and operative positions wherein they conceal the operating mechanism and give a finished appearance to the unit. Referring particularly to Figs. 2, 3, 4, '1 and 8, a panel |10 is pivotally mounted for swinging movement about a horizontal axis |1|, as by means of brackets |59 secured to the frame just below the xed panel fil. This panel |10 includes a portion '|12 extending across the unit below the axis |11 which is adapted to be engaged by the top of the hopper seat 80 when the hopper closes, means such as rubber buttons |13 being provided to cushion the seat as shown in Fig. 4. The arrangement of this panel is such that when the hopper is closed, its seat forces the panel to Swing forward and downward into a position overhanging the cover tray 15 as shown in Figs. 1 and '1, in which position the front of panel is substantially ush with frame -panel 01', as shown. to impart a substantially unbroken appearance to the hopper. When the hopper starts to open, torsionsprings |14 cause the panel portion |10 to spring upwardly about its pivot axis |1|, as shown in Hg. 7, thus releasing the hopper to complete its opening movement, and the panel remains in this retracted position until it is returned to its closed position byV contact between the hopper seat 00 and the rubber buttons |13 on panel portion |12 when the hopper closes.

Another panel is mounted within the frame for movement into a position concealing the space above and behind the hopper and the operating mechanism therein when the hopper opens. Referring particularly to Figs. 4 to `8, it will be seen that this panel |15 has .a pair of rearwardly projecting ears |16 adjacent its upper corners which are pivoted on a rod |11 mounted in the same brackets A|59 as the panel |10. A torsion spring |18 Figs.5, 7 and 8) is mounted on rod |11 in position to urge panel |15 normally into a retracted position, as shown in Fig. 1, when the hopper is closed. Y

Means are provided for causing panel |15v to swing forward against spring 18'when the hopperopensV and for `holding the panel in the resulting advanced` position. Referring to Figs. 6, '7 and 85 two brackets |80 are welded or otherwise secured tothe back of panel |15 at opposite sides of the frame. These brackets extend downwardly below panel |15, and each bracket' is formed with a convexly curved rear edge |8| terminating at its upper end in a slot |82. The front edge of each bracket is straight except for a slot |83 formed just below the lower edge of panel 15, as shown in Fig. '1,

The hopper tray 15 carries means for engaging brackets |80 to swing` panel `|15 forward when the hopper opens.` Referring to Figs. 6 to 8, at either side of the'hopper the tray flange 1 1 has welded or otherwise secured thereto an arm |85 including a forked outer end inwhich an upwardly extending lever |85 is pivotally mounted on a pin |81. A torsion spring |38 isarranged on pin |81 in postion to urge lever |05 outwardly,

i. e., counterclockwise 'as viewed inFigs. 7 and 8,

'and the lower'end 'of vthe lever is turnediover at |85 to engage a. shoulder |90 on the fork |85 to limit this outwardrnovement. At its upper end, each lever lilcarries a roller |5| `of proper vsize to fit within the r'slots |82 in brackets |80.

The operation of` theseparts in moving panel |15 is illustrated in Figs; 6 to 8. When the, hopper is closed, the panel is in the position shown in Fig. 1, andthe rollers 19| on.' leversllb" ride against angle irons |32, secured to' the' rear pair of channel irons 21' asfsh'o'wn' in Figs.. 6 and 7. As the hopper starts to open, the tray 15 raises arms |05 and a1so`rnoves them forward Vuntil the rollers '|94 arefir contact with *the curved edges iSl of brackets` iSd. As the hopper continues to open, the levers |85 act through rollers 50| to swing the panel 15 forward, during which movement the rollersv |9| ride up bracket edges itl until they enter slots 162 Yas ,the hopper reaches its fully opened horizontal position, thus locking the panel |15 in forward position as shown in Figs. 2 and 8 and also in Fig. 4. Itl will also be seen in Fig. 8 that in these relative positions of the parts, the upwardly flared rear. edge 18 of hopper tray A15 will enter Vthe slots |83 atthe front of brackets |30, as shown in Fig. 8, thus forming an interlock between the panel |15 'and tray 15 eifectively closing thev interior of the unit as showninFig-4. p

It will thus be seen that these panels 88, |10 and |15 not only cooperate with the hopper to provide a smooth and finished appearance, but in addition they greatly facilitate the maintenance of properly clean andV sanitary conditions for the unit. When the hopper is closed, as shown particularly in Fig. l, the smooth arrangement of the fixed and movable panels and the skirt 35 avoids the forniationof pockets or crevices in which dust and dirt can collect and thus simplifies effective cleaning. f The same is true of the cooperative action of panel V|15 andthe hopper tray 15, the panel serving as a splasher back when the hopper is open andthus both shielding the interior ofthe unit and. facilitating cleaning of the hopper when open. In addition, the flushing system as described and shown assures effective ushing of 'the bowl to assure sanitary conditions at all times. y

A member such as a foot treadle-200 is provided for actuating the iiushing valve` |21, and this treadle is mounted for movement in response to opening movementV of the hopper from va` retracted and substantially inaccessible position' wherein it is inoperable to an advanced operating position whereY it is readily4 accessible..Y Referring particularly toFigs. '1i to 1l, the treadle 200. is mounted. on a carriage 20| which in, turn ismounted for sliding movement on a pair of rails.202 supported. in brackets v203 at the bottom of theframe25. The treadle. 200` is mounted for rockingl movement in a vertical plane. on a pin 204.4which is carried by a vertical. stud 205. mounted inthe carriage 20|, and a torsion spring 20G (Fig. 11) is arranged to` urge stud 205 normally to a position in wh'ich'thetread-le 200 issubstantially-parallel' to the` rails. 202 as shown in Fig. 10. A spring 201 is positioned between the treadle and carriage 20| to hold the treadle in a normally substantially level position, and a rubber buttonv 208 isi-secured under the Outerend'of the treadle asa cushionvfor engagingthe floor when the treadle is actuated-l 'l'he-irmerl end ofthe treadle 20|) is formed into an arm 2|0n which isadaptedto engage a laterally extending trunlriionZllon one arm 212' of a bell'Y crankA lever pivotally mounted in a bracket 2 I3 in theframe as shown in Figs. 9and 10. The other arrnv2lk4 of this lever extends under the operating plunger 2|5- ofthe nushingvalve |21 as showninFig. 1l, the valve having been removed in Fig. 9. to show parts which .would other- Wise be concealed thereby. p A spring 2|6'is` positioned under lever arm 2|4 and substantially in line with the.,plunger 2|5V to' hold the lever arm in contact with thejplunger and thus to prevent chattering', It'will be understood that when the treadle. is depressed, its arm 2|!)- will engage trunnionY 2|I and thus raise lever arm 2|2, which will inv turn raise lever arm 2I4 against plungerl 2|5 and thus open valve |21' to admit flushing waterto the hopper bowl as described.

Referring to Fig. l0, itV will be seen thatY the treadle 200 and lever arm2|2A are so arranged that when the treadle is in position parallel with the rails202, its arm portion 2l 0'is laterally withdrawn andspaced fromthe trunnion 2H and means are provided for causing lateralswinging movement of the treadleat is reaches its'outermost position in such manner as to bring its Varm 2|0Qinto desired operating position under. the

trunnion 21|. Referring to Figs. 9 and 10, vthe treadle includes a forked; portion 220.which car-'- ries a. roller 22| arranged onla vertical axis for contaet'rwith a can; 222^In u1ntedontheinner` brace plate, "I4-0f theiframei., This cam is. O ff` such conilguration and so positioned in theframe, as shown in Figs. 9. and l0, that as the treadle approaches its outermost positionL the roller 22| will engagethe. side of the cam and thus force,

the treadle to swing about the vertical axis of pin 205, in clockwise direction as' viewed in Fig. 10, to a position in which its arm 210 engages .under trunnion 2| las shown in Fig. 9; It will also be noted thatY this motion provides for swinging the outer end ofthe treadle out to a more convenient position for ready actuation than if the treadley outer` flange A226 forming a drum for receivingacable221; One-end of .thiscable passesthrough a ange 228- at onev end-fof the-sector'225- and is secured to a spring 229. From. this springthek cable passes partwayV around: the` outer side of the sector and is then. looped around a pulley 230 mounted in the frame adjacent the inner ends of rails 202. The. cable is then fastened' at 23| to a collar 232Y loosely mounted? on the vertical pivot stud 205 ofv treadle 200, the collar in. turn being held on thestud by means-such asa snap ring 234. From thecollar 232, the cable islooped' around another pulley -235 ina bracket-236 at the front of the frame, and'iinally` back around the inner side of sector 225 througha flange-231 atr the opposite endA ofthe sector' from flange 228, and its` end is secured to a spring238.'

The operation ofthis-treadle-advancing andretracting mechanismis illustratedin-Figs; 1V to-10: When the hopper isclosed,Ythe-partswill be-inthepositions shown in Fig. `'7; `with the Vtreadle re tracted into the frame, Whenthe hopper-starts to open, the sector 225 rocksY withtheY hopper about the axis of thetrunnions'l02, andthecable 221 will unwind frornthe outerY sideA of thesector andsimultaneouslywind on the inner sideof the sector.

During., this movement; the springs22.5and-238will keep the cable under tension, andtheV torsion spring 296Y will tend' te keep, treadlen 200r in line. withthe cable and'rail's1202" as sh'owniin'Fig. 10'. However, as the treadleappr'oaches itsoutermost' position, the roller 22| will engage .cam222', foro-,- ing the treadle to swing` about'sti1`d^205V and'carrying its arm2|0 under trunnion 2li as' shownin Fig. 9 as` the hopper reaches itsopen position, Thus with this. construction, the vtreadle isnot only retractedout. of the way when the hopper is closed, butit. cannot be `actuat'edto open valve |21 except when it is-initsadvanced. position, thus eiectively preventing flushing andresulting. waste of' water exceptwhen the hopper is open.

Oneendof rod 24 |V extendsv outwardly of bracket-Irame-B'Bg anda lever arm 242* is clamped or otherwise secured thereto as shown in Fig. 14. One end of a Bowden wire 243 is secured to this lever 242, as by means of set screw 244, and the sheath 245 of this wire may be secured to bracket frame 68 by means such as a suitable clamp or clip 246. The wire 243 is looped loosely over the adjacent mechanism as shown in Fig. 3, and its other end is secured as shown in Fig. 9 to a clamp 241 carried by an extension portion 248 of the lever 2|4 which actuates the plunger 2|5 of the flushing valve, the other end of the wire sheath 245 being clamped in the frame adjacent lever arm 2|4 as indicated in Fig. 9.

A dash pot 256 and spring 25| control movement of apper valve 246. Referring to Fig. 14,

the dash pot 256 is carried by a bracket 252 secured in any suitable way to bracket frame 68. The spring 25| is mounted ona rod-'253 slidably supported in bracket 252 and having its upper yend pivoted to an arm or link 254 secured to rod 24|. A member 255 is secured to rod 253 above spring 25| and is slotted to form a yoke straddling the upper end of the piston rod 256 of dash pot 256. The piston 251 .is constructed with a check valve 258 arranged to permit rapid movement of the piston downwardly in Fig. 14, in a direction compressing spring 25|l but to vretard return or upward movement of the piston.

It will be seen that with this construction, when the hopper is flushed by actuation of treadle 266, the lever arm 2|4 will force the Bowden wire 243 upwardly, thus forcing lever 242 to swing in clockwise direction as viewed in Fig. 14. This will in turn cause rod 24| and the flapper valve 246 to swing in the same direction, to the position of valve 246 shown in dotted lines in Fig. 14 in which it opens the discharge outlet 61 for free passage of the flushing water and other contents of the hopper. At the same time, link 254 will swing in the same direction and will force rod 253 and yoke 255 downwardly against spring 25| to cornpress the spring and to move piston 251 downwardly in the dash pot cylinder, the slotted construction of the yoke providing for the necessary relative angular movement of rod 253 and piston rod 256.

The flapper valve 246 will remain open so long as the treadle is depressed and flushing continues. Thereafter, when the treadle is released and lever-arm 2|4 returns to its inactive position under the force of the usual spring in valve |21 for holding its plunger 2 I5 in closed position, the spring 25| will expand and will force yoke 255 and rod 253 upwardly, thus acting through link 254 to rock rod 24| in the direction to close valve 240. This closing movement will be retarded by the action of dash pot 256, to prevent undue noise. 1t should be noted, however, thatrvalve 246 is preferably not in tight sealing relation with the discharge outlet, thus permitting complete drainage of the bowl when the hopper is moved to its substantially vertical closed position.

Fig. 16 illustrates, as a modification, electric means for controlling the flapper valve 240 in response to actuation of the flushing means of the hopper. As shown, a solenoid 260 is mounted at the back of the pipe 10, and its plunger 26| is connected by means of a link 262 with the back of the iiapper valve. A spring 263 is arranged to urge the plunger outwardly when the operating coil of the solenoid is deenergized, and thus to urge the ilapper valve 246 to its position shown in dotted lines wherein it substantially closes the discharge outlet .of the hopper. Theiushing valve |21 is shown somewhat diagrammatically as positioned with its plunger 2|5 arranged for direct actuation by a foot treadle 265 which is shown diagrammatically but corresponds in function and operation to the treadle 200, this treadle 265 being shown as fulcrumed on a bracket 266. A normally open electric switch 261 for controlling current to the operating coil of the solenoid 250 is positioned with its plunger 268 or other operating handle arranged to be engaged by the treadle 265. Preferably the switch 261 is of such construction that it will be closed as soon as its plunger 268 is moved inwardly, but with this plunger capable of continuing inward moveu ment after the switch is closed.

With this construction, the plunger 268 is so arranged that it will close switch 261 as soon as the treadle 265 is actuated but before the treadle has pushed plunger 2| 5 a sufiicient distance to open valve |21. Accordingly, it .will be seen that when the treadle is depressed to flush the hopper, it'will close switch 261 and thus energize the solenoidV 261 before it opens the flushing valve. As a result, the valve 240 will be opened by retraction of the solenoid plunger 26| before the flushing valve is opened, and similarly when the treadle is released, it will cause closing of the valve |21 before switch 261 is opened, thus providing for completing discharge of the flushing'water from the hopper before solenoid 26|) is deenergized and thus before flappcr valve 246 is closed.

Figs. 17 and 22 show, as a further modification, hydraulic means for operating the lapper valve 240. A hydraulic cylinder 216 is connected by a pipe 21| to the main line |25 of ushing water ahead of the flush valve 21, thus connecting the interior of cylinder 210 directly to pressure in line |25 at all times. The piston within cylinder 210 is provided-with a spring 212 of such characteristics that when full line pressure is applied` within the cylinder, the spring will be overcome and the piston will be forced to its outermost position in which its piston rod 213 will force the iiapper valve240 to its position substantially closing the discharge outlet of the hopper. At the same time, this spring 212 is of such strength that when there is a drop in line pressure as a result of opening valve |21 to iiush the hopper, it will move the piston inwardly of cylinder 210 and thus permit valve 240 to open. The piston rod 213 may be provided'with a linked connection to valve 240 similarto that shown in Fig. 16, or the valve may be counterweighted in such manner as to open when the pressure of the piston rod against its rear side is removed.

With this construction, as shownin Fig. 17,

when the treadle 215 is depressed to force valve plunger 2|5 upwardly and thus to open valve 121, ilushing water will be admitted from the line |25 to the hopper, which will cause anl irnmediate "drop in line pressure effective within cylinder 216. As a result of this drop Vinpressure, the spring 212will be able to move the piston inwardly of cylinder 216, and 'thus to cause opening of ilapper valve 240. This condition will continue so long as the ilushing operation, since the line pressure will remain reduced as long as the water is in motion past pipe 21|.v After flushing is completed and the treadle released, thevalve |21 will close and will thus restore full line pressure in pipe 21| and cylinder 210, and this in turn will force the piston outwardly of the cylinder and so return valve 246 to its closed position.

Referring to Fig. 18, it will be` apparent that when the hopper moves between ,its open and closed positions, the pipe which connectsv its discharge outlet-'with the main drain pipe 55 telescopes within pipe 55, andit is important to keep the connection between these two pipes substantially liquid tight toprevent leakage. Accordingly, means are provided for effectively sealing the joint between these two pipes while at the same time permitting not only free telescoping movement betweenthem-but also alimited degree of angular movementi to allow for play in the pivotal mounting ofthe* hopper itself.V As shown in Fig; 18,. the' pipe. 55' is' Y- shaped at its upper end, witlrth'e pipel10 entering the back of thelY and being' capable ofi telescoping movement towards the front. wheny the hopper closes, this front 'armi of pipe- 55' being shown as provided with a4 removable cap280 for ready cleaning of the pipe;. l

When the handle is raised by the operator, it pivots in counterclockwise direction as viewed in Fig. 20, thus causing its camming surfaces 296 to move relative to iingers 295 and to urge followers 293and rods 290 inwardly. This in turn causes latches d6 to' be retracted to unlocked position and permits the lavatory to open. When the lavatory is closed, the cammng. surface 298 of latches 46 engage the sides of the frame and thus cause the latches toY retract sulliciently to enter the frame after which springs 292' return them to locked position.

Fig. 2'2 shows a modified arrangement of piping suitable for use in the toilet unit of the invention as described and shown in Figs. 1 to 21. As already pointed out, the piping: diagram in4 Fig. 22 includes a hydraulic' cylinder 210 forv controlling the lapper valve at the discharge'outle'tof the hopper, this cylinder being connected through pipe 21| directly with the main line|25 of ushing. water ahead 0f the flush valve |21, which is connected to line|25 by a' pipe |26 in the same manner as already described and shown. The valve |21 also is connected-as shown in Fig. 21 by' a' pipe |28 with theivacuum breaker |29, but the connection from the vacuum breaker to the jet fixture ||0 is provided by a pipe 300 and a flexible hose 30| in place'of'theV swiveled coupling |3| in Fig. 21 to allow for opening and' closing movement of the hopper relative topipe' 300.

Fig.22 also shows a modifled'arrangement for controlling the flow of water-toand from the hydraulic cylinders |40 which open and'close the hopper. The pipe 303 is arranged to supply cold waterto the lavatory faucet, and a branch pipe 304 leads from pipe 303'to a four-way va1ve'305 shown as provided with a sliding control member 306-. One pipe 3|!) leading from valve 305 is connected by means of flexible hoses 3|| with the lower sides of the hydraulic cylinders |40." Another pipe 3|2 leads from the valve 305 and connects through flexible hoses 3|3- with the upper sides of the cylinders` |40. The fourth pipe 315 from valve 305 leads to ar reservoir 316' positioned substantially above the plane of the hopper. This reservoir is in turn connected through a pipe 3|1 with a valvef329 provided with an operatingbutton v32| and connected by anexible hose 322 with one of the shower ring pipes |20, the pipe 3|1 being provided with a suitableone-way valve 323 to preventthe-upward now vrof' water therethrough.` An overilow pipe 324 leads yfrom the reservoir SIG-tothe 'discharge tank ofthe lavatory, which is indicated diagrammatically at 325 and corresponds in function to the tank 5| in.Fig. 2.

In the operation of this pipingv arrangement, when the valve lever 306 is movedto its"Open position, itwill connect pipe 303 with pipe 3|0 leadingto the lower sides-of the cylinders |40 and atthesame time will connect-the upper sides ofcylinders |V through the pipes 43|2 and 3|5 tothe reservoir 316. This-will cause the'hopper to open, and atv the same-time-wll--cause waste water. from the cylinder 340 to vbe-conducted to thevreservoi r..3|6.fV The valve 320 -is so positioned in the frame `that its operating button 32| will be engaged and moved to open position by the hopper as it reaches its own horizontal open position, for-example during the last approximately 8" ofthe hopper movement. As a result, the waste water which has been forced up. into reservoir 3|6 uwill flow through pipe 3|1, vvalve 320 and hose y322 into the shower ringpipe |20 and tlierrc'einto the` hopper bowl Ito `provide the' deird preliminary flush or wet bowl. When the valve control member 306 is moved to its Close position, the converse operation takes place, with thehopper being closed and the waste water from the lower sides of cylinders |43 being similarly forced through the piper 3|5 to the reservoir 3|6. This water will thus be collected in the reservoir for the next opening movemen-t of the hopper, and any excess water in the reservoir will be removed through vthe overflow pipe .324 to drain tank 325 and thence to the main drain of the unit. The valve 323 prevents waterfrom traveling up vpipe 3|1 to reservoir 325 during liushing of the hopper.

Figs. l and 2 illustrate an arrangement of light sources 36 and 31 for the mirror 35 to provide effective illumination on the face of the user without direct glare in the users eyes. The frame includes housings 33D and 33| for light sources which are positioned respectively above and below mirror and extend forwardly of the vertical plane of the mirror. These housings are located in predetermined positions which are correlated with visibility characteristicsl of the eyes of .thenormaluser so that adequate light is produced and cast upon the faceof the user, but direct glare is effectively avoided. This is accomplished through utilization of the fact that with the'eyes looking straight ahead, the normal range of vision or perception of lighted objects extends over a considerably greater angle ina horizontal plane than it does in a vertical plane. In accordance withk thepresest invention there are no light sources at the sides of the mirror within the normal wide horizontal range of vision, and r hence no glare is produced in the eyes of the user. The light sources are confined to the areas above and below the mirror and are located in such positions that they are primarily beyond or outside the range where full visibility occurs, either as viewed directly or by reilection in the mirror, and yet l.are so arranged as vto project lightdirectly upon the face of the user to give good illumination thereof.

Referring to Fig. 2, the housing 330 above the mirror has a panel 333 removably secured thereto as bymeans of bolts 332, and this panel carries brackets 334` forming a mounting for a directingthe light from the tu-be forwardly from the mirror and upwardly. The housing 33| is open at thefront and is provided with a hinged panel 3132 carrying a diffusing plate 343, and this,v panel and plate are arranged to slope downwardly away from the plane of the mirror at an angle of more than to the horizontal, for example an angle of 60. Thisk arrangement'of the reilector and the diffusing plate provide for directing the light from the uorescent tube 34|) Vforwardly of the mirror andupwardly at angles, of the order of substantially 30 to the horizontal, as indicated by the dotted lines Fig. 2, it having been found that light directed in this manner will effectively illuminate the lower part of the faceofl the user of thevmirror without impinging directly on the` users eyes, as illustrated fluorescent tube 335 arranged substantially horiv zontally within the housing. A reflector 336 is secured to panel 333 within the housing for directlng light from the tube 335 generally downwardly,.and the panel'ls cut out to receive a plate 331 of frosted glass or other suitable translucent material arranged in position to transmit the light from tube 335 and reflector 336 downwardly and forwardly of the mirror. In addition, as shown in Fig. 2, the panel 333 is so formed that its lower portion and the plate 331 arearranged to slope upwardly away from the mirror at an angle of somewhat less than 45 to the horizontal, for example an angle of 30. With this arrangement thelight from tube 335 will be directed forwardly of the mirror and downwardly at angles of the order of substantially 60 to the horizontal, as indicated by the dotted lines in Fig. 2, and will thus eiectively illuminate the face of the user of the mirror from above but will not pass directly to the users eyes, as is illustrated by the fragmentary showing of the figure of a user in Fig. 2.

It will be noted that the tube 335 and all of its associated parts within housing 330 are supported by panel 333, thus substantially simplifyingfshowing ofthis part of the unit. With this inFg. 2. In additionfit will be apparent thatv if light rays from either of tubes 335 and 343 fall directly cn the mirror, their angles of incidence will be such that they will be reflected well outside of lthe normal range of vision of the user, thus effectively preventing reflected glare.
