This invention relates to improvements in water closets, bidets and similar appliances of the type where the cleansing Operation is performed by means of a jet of water, followed by a drying jet of air; More partic'u larly the invention refers to improvements in methods of and apparatus for supplying to the nozzle air under pressure, in order to perform the drying operation. I

An attachment for water closets or bidets making it possible to direct a jet of water against the body of the user for cleansing purposes, has'been described and ;claimed inapatent application, entitled, Sanitary attachment for water closets, Ser. No. 455,554, copending herewith; The device to which said application refers also comprises a front, wardly directed air discharge outlet atthe rear and a rotary fan supplying the. air thereto, 7 V V; a

In another copending application, entitled Methods of and apparatus for sanitary cleansing, Ser. No. 283,234, we have described and claimed improvements in amethod and apparatus for directing a jet of -water and a jet of air against the spot to be cleansed and dried, said improvements being particularly directed to the fact thatboth jets aremade to issue from a nozzle in close proximity of the surface to be cleaned, and so that they will reach the proper spot at a velocity suiiicient to insure thorough, efiective and rapid action. 7 V

In addition to these remarks, it is also to be noted that in a great many localities, electric power is not as yet available, so that the use of the apparatus shown and described in application for method of and apparatus for sanitary cleansing, SeraNo. 483,234, would J be out of the question in such places, On

the'other hand, water is always available practically all overthe world at pressures sufiicient to permit its potential energy to be used in supplying air to the nozzle of the apparatus at the desired pressure.

Accordingly, the primary object of this invention is to provide a novel and improved method of supplying air under pressure to an apparatus of the classspeciiied, whereby the necessary pressure is obtained by utilizing the pressure of the water obtainable froin the a same'sourceof supply which is flushing the toilet'orbifldet,

Other Object is to p i pparatus of the class specified,'a' novel and, improved arrangement for operating the apparatus, entirely by means of the water supply to which the apparatus may be connected.

A further object-is to provide a sanitary.

appliance to be-used inconnection with or forming part of awater closet or bidet, permitting of directly transforming the pres sure of the wateravailable from the" water supply into pressure of air-issuing asfa dry ing jet from a' nozzlev forming part of the: apparatus. g 1 j -A still further object is to provide .in a water closet or bidet, equipped with means for efl'ecting a body cleansing operation by means ofajet of liquid directed against the exposed parts of the body of the user requiringit, means forv supplying air to a properly located nozzle under a positive pressure sufficient to insure a' quickand'effective dryinga direct and substantially noiseless utilization ofthe pressure available in the water supply.

.Otherobjectsan'd advantages of the pres.- Vent invention will more fully appear as the description proceeds andfwill beset forth and-claimed in the appended claims;

Our invention is illustrated by way of enample, in the accompanying drawings, in

Fig. 6 is a fragmentary side view in eleva-' tion of the stand,showingc-thecontrolling valve; a I Y5 Fig. 7 is a cross sectional view of the controlling valve shown in Fig. 6; and

Fig. 8 is a fragmentary longitudinal section of the tip end of the preferred form of nozzle used in connection with our invention.

The jet of water used for the cleansing operation proper should preferably be 'di rected at a slant so as to avoid splashing and so that it will at the same time actually carry away particles of foreign matter adhering to the spot to be cleaned by impactor mechanical action.

In order to obtain an efficient drying action, a jet of air, preferably heated, should also be sent against the spot to be dried under a. positive and material pressure froma point of issue relatively. close to said spot. The air thus delivered should also preferably be at aslant to the surface to be dried so that as a result of these various conditions, the

air will be supplied in a volume suflicient to induce quick evaporation and also at a relatively high Velocity causing saidair to blow quired for drying it. p a

. For the purpose of our invention it is'preferable that both the water and air supplied to the nozzle ornozzles be heated, although.

this is not a necessary condition, the use of the heating facilities provided being entire- 1y, if desired, under the control of the user.

Referring to the drawings, 10 designates ,7, a toilet bowl of usual construction compris- 35 ing a base 11 and a rim 12 formed with a passage 13,'through which water flows from asuitable source of supply in order to flush the bowl in thecustomary manner. The

, bowl is provided with a seat 14 on top which is hinged at 15 to the rear of the bowl the lower surface 16 of the seat is usually pro vided with rubber spacing heads 17 resting upon the top of rim 12 causing a clearance 18 to remain between the top of the bowl and o the lower surface of the seat.

The cleansing and drying device proper preferably comprisesa stand 19, having a base 20 adapted to be placed upon the floor alongside the toilet bowl.. At the upper end of said stand is mounted a head 21, carrying all the operating and controlling parts, the bottom part 22 of said head forming with a cavity 23 at the upper end of stand 20, a

. chamber to which water under pressuremay be admitted through pipe 24. The portion of said stand underneath chamber 23 is hollow, forming an air chamber 25 connected by an opening 26 at the tip to a passage or chamber 27, within which projects an electric heating element 28, adapted to heat the air on its way from the chamber 25 tothe nozzle through delivery passage 29 atthe upper end of the stand and delivery passage 30 registering therewith, provided in head 21. I

The bottom 31 of water chamber 23 is prefher.

A nozzle supporting member 32 operable, by means of a handle 33 is rotatably mounted on head 21 so as to be angularly movable about a vertical axis. Said supporting member is carried by a tubular shaft 34 which is formed integral with an outer shell portion 35 forming an annular chamber 36 surrounding said hollow shaft. The lower surface 37 of shell 35 formsa seat determining thedepth at which the shaft andshell can be inserted, within head'22 and the lower end of hollow shaft 34 is threaded as shown at 38, to receive nut 39, restraining shaft 34 against axial displacement while permitting angular.

movement thereof. Hollow shaft 34 forms a tubular passage 40 leading fromcavity or chamber 23 to another chamber 41 within supporting member 32. Air passage 30 leads to a .chamber 42, surrounding a tract of shell portion 35 which is provided in correspondence of said chamber with circumferential openings such as 43 through which air may be admitted to annular chamber 36.

' Supporting member 32 carries afluid delivery arm 44, which terminates in a nozzle portion 45. In its preferred form the fluid delivery arm comprises an inner tubular member 46 forming an outlet for chamber 41 and an outer tubular member 47 forming with tubular member46 an annular chamber 48 constituting an outlet for a chamber 49, to which leads the upper end of shell portion 35. Said two tubular members 46, 47 together form the fluid delivery arm. Said delivery arm preferably comprises a horizontal tract 50 which isflattened so as to permit it to pass through clearance 18 between the seat and the top of the bowl, a substantially vertical tract 51, bent downwardly from the outer end of horizontal tract 50 so as to reach a point somewhat below the level of the lower surface 52 of rim 12, and a substantially horizontal tract 53 bent underneath the rim and then extending close to the side surface of the bowl as shown in dotted lines at 53, in Fig. 1.

The device is normally inoperative and in this condition supporting member 32 is in the angular position in which the delivery arm occupies the positionshown in dotted lines at 53 in Fig. 1.

When from this position the supporting member is moved by means of handle 33 to the position shown in full lines in Fig. 1, nozzle 45 carried by tract 53 comes to occupy a position within the bowl in which its axis remains on a vertical longitudinal plane passing through the center of the bowl and is up- 7 angles to the central longitudinal plane of the bowl when the fluid delivery arm 44 is moved to its operative position, shown in full lines in Fig. l. The nozzle tract can therefore be elbow-shaped and can have its tip end at right angles to the ends of its attaching end.

A typical construction of nozzle designed along these lines is shown in Fig. 8, in which the outer end 46 of tubular member 46 is threaded as shown at 54, and projects beyond the outer end 47 of tubular member 47 which is also threaded as shown at55. Thenozzle proper comprises an outer shell 56 bent at a" 90 angle forming an internally threaded sleeve portion 57 which may be screwed upon the outer end 47, and atip end 58 directedat right angles thereto, said tip end being preferably inwardly tapering towards the nozzle outlet 59. Said nozzle furthermore, comprises an inner tubular portion 60 which is also bent at a- 90 angle forming aniinternally threaded sleeve portion 61 which may be screwed onto end 46- and ajtip portion 62 coaxial with tip portion 58 forming therewith an annular passage 63.. 1 It will be seen that by virtue of this arrangement, the inclinationof the axis of the tip end of the nozzle with respect to a longitudinal vertical plane passing through said axis and through the center of the closet bowl can be adjusted at will, the nozzlebeing retained in its adjusted position by means ofzja check nut 64. The tip end 58 of the nozzle is preferably provided with an inwardly flaring sleeve 65 forming therewith an annular passage 66' through which air may be drawn by the suction created through said passage by'the jet of fluid under pressure issuing-through outlet 59. Air is supplied to chamber 25 within stand 19 by a pump actuated by the water available from the water supply. In the preferred embodiment of our invention, weu'se in connection with stand 19 and head 21 a controlling valve 67 by means of which the supply of water to the nozzle or to the pump and the supply of air from the pump to the nozzle can be selectively controlled.

' Said valve is so designed that in its inoperative position, no flow of either water or air takes place. By moving said valve one step forward .the'waterfrom the supplysystem will be directedto chamber 23 through pipe 24, so that a cleansing spray will issue from nozzle'45. By moving the valve to its next step, the water from the water supply will be directed to the hydraulically operated pump, and the air under pressure delivered by said'pump will be directed by the valve 1 through pipe 68 to air chamber 25 and will reach *outer passage 48 of the fluid delivery arm ultimately issuing through'nozzle 45 in the form of a jet of air under pressure. a Y

Thecontrolling valve-is shown in Figs. 1 and 2, and .is also illustrated in detail'i-n Figs. 6 and7. From said figuresit willbeseen that the valve comprises a body 69.

mounted on head 21, said body being pro.-, vided withvariousports of which: .70 is a port for the admission of water from the water supply through pipe 71, controlledby a valve 72;"73 is a port for the discharge of said water through pipe 24 leading to water chamber 23 in the stand; 74 isa port leadingxthe water'to-theair pump through a pipe 7'5; 76-is a .port leading the air under pressure from the air pump to the valve through a pipe 77; and 7 8 is a port leading the air from the Valve to the air chamber.

25 through pipe 68. I V j V The valve also comprises an angularly movable-member or cook 79 provided with tubular passages 81, 82 adapted to establish thevarious connections between the ports mentioned required bythe operation of the device. SaidFcockisprovided with an operating handle 80 which is shown in Figs. 6, 7 in its first operative position marked #2 in Fig. .6, the normal or inoperative position of said handle being markedqfitlat the left hand 1 in Fig.6 and-the second operative; step of the same figure. 1 v v ,7 In theiposition shown, water from the supsamebeing markedfl#3 at the right inthe ply system is directed to" chamber 23 in the stand for. the cleansing operation, and'there-' fore passage 81 of cook 79 establishes connection between ports 70 and 7 3,'while the other ports ,are disconnected from one another.-. 7

After the cleansing operation has been completed, handle 80 isxmoved to the next position 3. Where-passage -81 ,of the cock will establish communication between ports 70 and 74 and passage .82 will establish communication between ports 76 and 78.

In this 'tposition'therefore, the water from the water supply will be directed to the pump, and the air dischargedby the pump will be deliveredthrough pipe68, to air chamber 25 and willissue from the nozzle 45 in the form of. a jet of :air under a suitable pressure, said pressure being preferably sufficient iis asstated, to blow oft l-iquid particles ,adhering to the Wet surface so as-to. increase the efficiency of the drying action.

The aircthus delivered,as stated, is preferably heated by any suitable means, for 1nstance, by means of the heating'element 28 which may be energized at the proper time. The water also is preferably heated and this may be done in various ways for instance, by admitting to chamber 23 some water from the hot water pipes by means of a suitable valve (not shown). In the arrangement illustrated, the water may be warmed up by the heat given off by the heating element 28, and thereforeisaid heating element may be energized not only when the air is flowing through passage .27 but also before when water is flowing through chamber 23 so as to issue from the nozzle in the form of a cleansingijetr We have therefore, illustrated an'arrangement whereby the igniting element will be energized as'soon asthe fluid delivery arm is moved to operative position by the angular displacement of supporting member 32. As Fig. 3 clearly shows, the heating element 28 is provided with two terminals 83, 84, one of said terminals being connected to a line wire 85 and the other one being connected by means of a wire 86 to one of the terminals 87 of a switch 88. Said switch has another terminal 89 to which is connected the other line wire 90.

From said switch terminals 87 89 respectively, project two contact clips 91, 92 having their tip ends opposite to but spaced from each other. Supporting member 32 carries at its lower end, a contact finger 93 which closes the circuit between clips 91, 92 when supporting member 32 is moved-to its operative position shown in Fig. 3, said contact finger again interrupting the circuit when said supporting member is moved to its normal or inoperative position. It is therefore obvious that heating element 28 will be energized as soon as the fluid delivery arm is set in its operative position, raising the temperature of the water contained in chamber 23.

- The water used in the pump to compress the air may be discharged in the sewer by means of a pipe 94 which may-for this'purpose be connected to the discharge end of the siphon-of the closet bowl, or to the discharge pipe thereof.

The water available from city supply systems is generally at a fairly high pressure so that its energy can readily be usedto pump and compress air at relatively low pressures required for the drying operation.

For the sake of example, in the drawings we illustrate a type of air pump which may be conveniently used incur apparatus, in which the water acts as a liquid piston directly creating the suction and the discharge of the air to and from the pump chambers.

Said 1 air pump comprises two pumping chambers- 95, 96, arranged side by side through which runsa shaft 97 carrying at one end a lever 98. Chamber 95 is provided at its lower end with a passage 99, and chamber 96 with asimilarpassage 100, said pas-- sages alternately acting as inlet and outlet forthe water admitted to or discharged from each chamber. A valve body 101 is fixed to the underside of chamber 95 in correspondence of passage 99 and a similar valve body 102 is fixed to the underside of chamber 96,

in correspondence of passage 100, said two valve bodies being in coaxlal alignment with each other. Valve body 101 is provided with WVithin valve body 101 is rotatably mounted a cock member 113, and within valve body 102 is rotatably mounted a similar cock member 114, said cockmembers being both fixed on the same shaft 115 for simultaneous operation. Shaft 115 has a portion projecting beyond valve body 102 carrying a lever 116 which is mounted substantially at the same angle as'lever 98 and is connected therewith by a connection 117 The two valve cocks are so arranged that when water is admit-ted to one of the pump chambers water'is discharged from the other, and vice versa. In the position shown water is admitted to chamber 95 through a passage 118, incock 113, said passage connecting port 103 to-port 104. At the same time water is discharged from chamber 96 through a pasin cock 113, said passage establishing com-' munication between port 103 and port 106, and water will be admitted to chamber 96 through a passage 121 provided in cock 114, said passage establishing communication between port 108 and port 109.

Chamber 95 is provided at the top with an air inlet 122 equipped with a valve 123, which will admit air within chamber 95 when a suction is created within said chamber. Said chamber is also equipped with an air delivery outlet 124 through which air will be expelled from chamber 95 when water is admitted to said chamber, said outlet being controlled by a valve 125. i

In a similar manner, chamber 96 is provided with an air inlet 126 controlled by a valve 127 and an air outlet 128 controlled by a valve 129. The two air outlets 124, 128 are. joined by a common fitting 130, to pipe 77- delivering the air from the pump to valve 67. On the pprtion of shaft 97 running through chamr95, is fixed a lever 131, carrying at its outer end a float 132, said lever being in its depressed position when water is being admitted to chamber 95 as shown. The hub portion of lever 131 is formed with a lug or projection 133 against which abuts the tip end 134 of a stop lever 135 pivotally mounted at 136, said stop lever being equipped with a depending float 137, carried by a rod 138 vertically shiftable between two guide pins 139, 140. 7

In a similar manner, the portion of shaft 97 running across chamber 96 is provided with another lever 141-carrying at its outer end a float 142, the hub portion of said lever being provided with a lug or projection 143 a'gainst which may abut the tip end 144 of a stop lever 145 pivotally mounted at 146, when lever 141 is in its downward position. Like in the previous case, stop lever 145 is equipped with a float 147 carried by a rod 148 vertically slidable between guide pins 149, 150. Lever 141 is angularly displaced in a clockwise di- .rection'from lever 131, so that when lever 131 occupies its downward position, lever 141 occupies its recessed position to the left as shown in Fig. 5. In this position, of shaft 97, rotation of said shaft in a counterclockwise direction is prevented by lever 135 having its tip end 134 engaging lug or projection 133, so that float 132 will not be able to rise as the water admitted through passage 99 gradually fills up chamber 95, Forthe same reason float 142 will not be able to. descend while the water contained in chamber 96 is being discharged through passage 100. i p

While water is being admitted to chamber 95 the air contained within said cha'mberis expelled through outlet 124 and pipe 7 7, said air ultimately reaching nozzle 45 as explained, since when water is admitted to the pumping chambers, the cock of valve 69 is in the position 3 of Fig. 6; In a similar manner as water isbeing discharged from chamber96 air will be admittedto said chamber through air inlet 126. f

When the water in chamber 95 reaches a level suflicient to raise float 138, this will cause lever 135 to become disengaged from lug or projection 133, and float 133 will'then be free to instantly ascend causing angular movement of shaft 97 in a counterclockwise direction. This angular movement will be shared by' lever 98 which will transmit it to lever 116 through connection 117 reversing the valve connections established by cocks 113,144. At the same time, float 142 will descend to the position where lug or projection 143 will be engaged bythe tip end 144 of lever 145.

Water will nowbe discharged fromchamber to supply water of air to the nozzle through pipe 77.

By virtue ofthis arrangement the operatlon of the pump is entirely automatic, starting assoon as lever 80 of valve 69 is moved to position Sand stopping as soon'as said- 1 lever is moved back to position 1.

The fiow of watermay be stopped by means of valve 72 when lever 80 is moved back' to position 1 in order to prevent water from isposition 1, or else the ports in'valve 69 and thepassages in cock 79'may be so arranged that the valve is in its inoperative position when the'lever occupies the intermediate position 2.shown in Fig. 6, beingmoved to one side or the other-of said position, in order or air to the nozzle, as will be understood.

. suing once more throughthe nozzle while lSZLld lever reaches position 2 on its way to From the foregoing, it will be seen that we provide a novel and convenient arrangement whereby the necessity of using an electric motor and a power operated tirely done away with. a
