13 Claims.

tachment for water closets, Serial No. 603,696,

co-pending herewith, I have described and claimed a water closet attachment of the charactor to which this invention refers, said attachme-nt comprising anoperating mechanism 5 and means for fastening it onto the bowl of the water closet or bidet.

The operating mechanism comprises a water delivery arm which is rotatable about its own axis with respect to a support therefor, which is, in its turn, rotatable about a substantially vertical axis. Said mechanism also comprises a system of valves controlling the supply of cleansing fluid to said arm support and delivery arm and a single member for actuating both 535 said arm support and said valves, the arrangement being such that a continuous movement of said actuating member in one direction from its normally inoperative to its operative position, will first bring the delivery arm to position and then will operate the valve or valves to cause cleansing fluid to flow to and through said arm.

An arrangement of the type indicated, entailing as it does the use of several parts mov- 3;) ing in the presence of water under pressure, re-

quires considerable care in its manufacture and also requires frequent inspections and adjustments, in order to prevent leakages which are bound to develop after a certain period of use.

I have found in practice that the difficulty of making and maintaining all joints water-tight constitutes a serious drawback to the adoption for general use of a sanitary device of the character to which this invention refers. The water supplied by the average city system is generally under a considerable pressure, and even small leakages are, therefore, likely to become seriously objectionable. I have also found that due 5:3 to the great variety of closet bowls in use it is difficult to produce an attachment which will be usable in all cases, or at least, it is diflicult to produce an attachment which can be readily installed without the expenditure of considerable time and labor, in order to insure the proper position of the fluid delivery arm with respect to the center of the bowl.

The primary object of this invention is to provide a sanitary attachment of the character specified, in which no valves or rotatable parts are employed in the path of the cleansing fluid between its source of supply and the point of delivery.

Another object of the invention is to provide, in a sanitary attachment of the character specified, comprising a fluid delivery arm movable from a normally inoperative to an operative position, a tubular connection directly connecting the fluid delivery arm to the source ofsupply, said connection being of such a nature as to permit at any time a free movement of said arm from one of its extreme positions to the other.

A further object of the invention is to provide, in a device of the character specified, comprising a fluid delivery arm movable between two posil" tions, a flexible compressible tubular connection between said arm and a source of fluid supply, and simple means for controlling the flow of fluid through said connection.

A still further object is to provide a sanitary water closet attachment of a novel and improved type, said attachment comprising a minimum number of parts enclosed in a relatively shallow casing or frame, adapted to be mounted directly under the water closet seat.

An additional object is to provide an arrange ment of extreme simplicity in which the fluid delivery arm is directly connected to the source of fluid supply without the interposition of valves or other moving parts and in which a single angular movement of said arm about its pivotal support is suflicient to bring the arm from its normally inoperative to its operative position.

Other objects and advantages of the present invention will more fully appear as the description proceeds and will be set forth and claimed in the appended claims.

My invention is illustrated by way of example in the accompanying drawings in which:

Fig. 13 is a vertical section of the same through line 1313 of Fig. 12.

As stated in the premises, the novel features of my invention include improvements in the operating mechanism proper, as well as improvements in the manner of mounting the device in position. The improvements in the operating mechanism are directed mainly towards the production of an extremely simple and absolutely reliable device where a continuous and direct passage is provided between the source of fluid supply and the point of delivery, so as to avoid the possibility of leaks developing at intermediate points.

The improvements in the manner of mounting the device in position are intended mainly to obviate the difficulties now encountered in applying sanitary devices to water closets of diiferent designs, and to provide a novel type of enclosure and support for the operating mechanism adapted to be attached directly under the water closet seat.

The basic principle of operation employed in the device forming the subject of my co-pending application above referred to; namely, an operating cycle whereby the fluid delivery arm is brought to position before the fluid delivery is started, has also been employed in the present case, because such an operating cycle constitutes an essential condition for the proper functioning of this class of sanitary devices. In fact, where the movement of the fluid delivery arm from its inoperative to its operative position is effected simultaneously with the movement of the valve controlling the fluid flow to a position of delivery from a position of non-delivery, the valve generally begins to be partly open while the arm is still moving towards its operative position, so that the cleansing fluid is likely to issue from the delivery arm before its proper position has been reached.

However, while, in a broad sense, the principle of operation has been retained, the mechanism itself has been simplified to the point where a minimum number of parts is employed. This reacts to the advantage of both the operation of the device and its cost of production, as will be clearly explained in the description which follows.

In order to avoid the difliculties engendered by the necessity of meeting conditions arising from the use of water closets of various sizes and designs, I have conceived the idea of attaching my device directly to the under side of the closet seat. Such a manner of mounting the device greatly simplifies the problem of applying it in the proper position, because the only precaution that has to be used is to make sure that the nozzle at the end of the delivery arm will remain centrally located with respect to the bowl. Such an arrangement also makes it possible to adopt a standard type of seat already equipped with the sanitary device attached thereto in its proper position and to simply substitute the unitary structure thus obtained for the ordinary seat when the device is to be applied onto a. water closet.

Referring to the drawings, 10 designates a toilet bowl of usual construction, formed with arim 11, surrounding thebowl cavity 12, and having a rear extension 13 carryinghinge bolts 14, 15, by means of which theseat 16 is attached to the bowl. Thelower surface 17 of theseat 16 is provided withrubber spacing feet 18, resting upon the edge of therim 11, causing aclearance 19 to remain between the top of the bowl and the underside of the seat.

The casing or frame carrying the fluid delivery arm and. operating parts of the mechanism, shown at 20, consists of a relatively shallow, open-top structure, extending under and across the rear portion of the seat withinclearance space 19, said structure being attached to the seat in any suitable manner, for instance, by means of screws inserted throughopenings 21.

The front part of the casing or frame is preferably formed with a lip 22, at one end of which is pivotally mounted at 23 thefluid delivery arm 24. When the fluid delivery arm is in its inoperative position, shown in Fig. 4, it extends transversely of the seat within the space intervening between lip 22 and theunderside 17 of the seat. Thepivotal support 23 of said arm is slightly inclined forward, as shown in Figs. 5, 6, 8, 9,

so that when the fluid delivery arm is angularly V displaced about said pivotal support to its operative position, shown in Figs. 7, 8, 9, it will be slightly inclined downwardly so as to cause itsnozzle 25 to remain vertically spaced a suitable distance from thetop 26 of the seat.

It will be observed from Fig. 7 that when the fluid delivery arm occupies its operative position, said arm is at an angle to the central longitudinal line of the closet bowl, but thenozzle 25, carried by the outer end thereof, remains set in said central longitudinal plane. Furthermore, by looking at Figs. 8 and 9, it will be observed that the nozzle is directed upwardly and is preferably inclined towards the rear, so as to produce a fluid jet 2'7, which will strike the body of the occupant of the seat tangentially or at a slight angle to the surface thereof. A. fluid jet thus directed will clean the surface efficiently and without splashing and due to its velocity will also carry away particles of foreign matter adhering to said surface.

An arm 28 extends inwardly from thepivot end 23 ofdelivery arm 24 through a passage 29 provided in thefront wall 30 offrame 20. To the end of said 28 is attached aspring 31, which is attached at the other end to a fixed point 32, and which tends at all times to move the delivery arm from its inoperative position, shown in Fig. 4, to its operative position shown in Fig. 7.

However, said delivery arm is normally retained in its inoperative position against the action ofspring 31 by alever 33, carried by the operatingshaft 34, saidlever 33 having a slot 35 (see Fig. 7) through which passes alink 36, pivotally connected at 37 to alug 38, laterally loo extending fromdelivery arm 24. The outer end oflink 36 is provided with a rounded orspherical head 39, which abuts against the outer surface oflever 33, and which forms therewith a sort of universal joint, permitting slight angular displacements of saidlink 36 with respect to said lever 3-3.

The retaining action oflever 33 uponhead 39 of link 36- is exerted by virtue of the action of a spring 40, urgingshaft 34 in a clockwise direction with respect to Figs. 5, 6, 8, 9, to its normal position shown in Figs. 4, 5, 6. Said spring 40 is connected to the inner end 41 ofshaft 34, while theouter end 42 of said shaft projects through and extends from casing orframe 20, saidshaft 34 being supported bybearings 43, 44, integral with said frame.

At theouter end 42, said shaft carries a for wardly extendingoperating lever 45 which, when depressed, will causeshaft 34 to rotate in a counterclockwise direction with respect to Figs. 5, 6, 8, 9, against the action of spring 40.

When such a movement ofshaft 34 takes place,lever 33 moving forward, makes it possible forlink 36 to move towards the inside of the bowl, and, therefore, makes it possible forspring 31 to cause the angular movement offluid delivery arm 24 from its inoperative to its operative position. It will, of course, be understood that spring 40 is strong enough to overcome the action ofspring 31 whenlever 45 is released, so that when this is done,shaft 34 will return to its normal position andlever 33 will pull back the fluid delivery arm by hearing againsthead 39 oflink 36.

The cleansing fluid, which is usually water coming from the water supply system, is supplied to the fluid delivery arm by aflexible tubular connection 46, attached to a lug 47 laterally projecting from said arm at a point in proximity to itspivotal support 23. Said flexible tubular con nection preferably consists of a compressible rubber tube, or at least includes acompressible section 48, which is normally flattened or pinched by theend 49 of alever 50, said lever being pivotally mounted at 51, and being urged to compress the tubular connection by the action of aspring 52 bearing against itsarm 53. Said tubular connection enters thecasing 20 through an opening provided at 54, through therear wall 55 of said casing and is attached to the fluid source of supply in any suitable manner.

Due to the clamping or pinching action ofpart 49 oflever 50,section 43 offlexible connection 46 is normally flattened so as to positively obstruct the passage of the fluid beyond the point against which end 49 bears.

Operatingshaft 34 carries acam 56, against which bears a lug 57 projecting fromarm 53 oflever 50, the action of said cam being to tilt saidlever 50, so as to cause itsend 49 to release the pressure exerted againsttubular connection 46, when after a certain amount of rotation of saidshaft 34, the fluid delivery arm has reached its operative position. It will be understood thatcam 56 will only start to cause the releasing action oflever 50 after the fluid delivery arm has reached its operative position, in order to insure a condition whereby the cleansing jet issuing fromnozzle 25 will be directed to the proper spot.

In order to define the point at which the fluid delivery arm will stop, an adjustingrod 58, passing through a bearing 59 and provided with adjustingnuts 60, is preferably attached to the outer end of arm 28.Nuts 60 are, of course, ad-

justable alongrod 58, so as to determine the extent of the angular movement of the fluid delivery arm, which will stop whennuts 60 come to rest against bearing 59.

Slot 35 inlever 33 extends sufliciently to permit the movement of rotation of operatingshaft 34 to continue for a while after the fluid delivery arm has come to a stop and during said period of additional rotation of saidshaft 34, the action ofcam 56 againstlever 50 will take place.

By virtue of this arrangement, after the fluid delivery arm has been brought to position the pressure exerted against thetubular connection 45 is released and the cleansing fluid will issue in the form of ajet 2? fromnozzle 25. As soon aslever 45 is released by the occupant of the seat, spring 40 will automaticflly cause all the parts to return to their normal position, shown in Fig. 4, overcoming the action of bothspring 31 andspring 52, the various movements taking place in the reverse order, that is, the supply of cleansing fluid to the nozzle being cut off before the fluid delivery arm begins to return to its normally inoperative position.

In the construction shown, wherelever 33 and link 36 are caused to project above the level of the under surface of the seat, the seat will have to be provided with a suitable cavity or cavities, such as 61, supplying the clearance space necessary for the operation of these moving parts.

In this case it is desirable, in practice, to supply both the sanitary attachment and the seat as a single unit and, therefore, thecasing 20 is shown formed integral withhinge members 62, 63,

adapted for attachment to hingebolts 14, 15, in j the usual manner. This, however, does not exclude the possibility of so modifying the construction of the device that it may not be necessary to provide cavities in the under side of the seat, so as to make it possible to attach the device 3 to any existing seat. In such a case, it will also be unnecessary to provide the device with hinge members, since it will be possible to utilize the hinge members already attached to the seat.

It is obvious that if desired,cam 56 can be so shaped that the pinching action exerted byend 49 oflever 50 against thetubular connection 46 will be released gradually so as to regulate the amount of cleansing fluid which will be allowed to reach the fluid delivery arm. This is especially l important whennozzle 25 is made suitable for the attachment of a rubber hose carrying at its other end a nozzle suitable for internal treatment by douches or enemas.

Whileflexible connection 46 may consist throughout of a length of rubber tubing having a round section, I prefer to make itssection 48, subject to compression ofend 49 oflever 50, with a normally oval or flat section, as shown in Fig. 11, itspassage 64 being in the form of a narrow slit which, of itself, tends to obstruct or impede the passage of the cleansing fluid therethrough. Such an arrangement makes it easier forlever 50 to totally prevent the flow of liquid through said passage and also prevents the tendency of the rubber to crack, which develops when a round rubber tube is frequently flattened by the action of a pinching or clamping member.

The water pressure in an ordinary water supply system is usually fairly high, so that when the pressure exerted byend 49 againstsection 48 is released, the water will automatically cause said section to expand, permitting its flow therethrough. It is, of course, quite possible to make the tubular connection proper of round rubber tubing and to provide the same at the proper point with oval orflat section 48, also made of rubber.

In apparatus of the character to which this invention refers it is frequently desirable to provide means for heating the water delivered at the nozzle. This is especially desirable when no source of warm or hot water supply is available and when the device is also made usable for internal treatment.

In order to take care of these requirements I have, therefore, shown an arrangement which can be adopted in connection with my device, said arrangement being illustrated in semi-diagrammatic form in Figs. 1, 3, i, 6, 7, 9. In the same it will be seen that water from the supply system reaches a receptacle throughpipe 66 and then reaches tubular connection i6, which is attached to the outlet of said receptacle at 57.Receptacle 65 is provided with suitable means for heating the water passing therethrough, for instance, electric heatin means (not shown), the terminals of which cs, 69, are inserted through the circuit of wire 70 of an electric supply system. Said wire 70 is attached toterminal 68, while the branch wire 71, originating atterminal 60, is attached to a contact member 72 and theother line wire 73 is attached to a contact member 74, said contact members 72, 74, being placed directly above operatingshaft 34. A hand-operable switch 75 is inserted in one of theline wires 73, providing means whereby the occupant of the seat may cause the water issuing from the nozzle to be cold or warm, as he may wish.

The electric circuit is normally interrupted at 72-74, but connection between said two contact members is established by acontact drum 76, mounted onshaft 34, as soon as said shaft starts to rotate when pressure is exerted againstlever 45.

In other words, the electric circuit of the heating means is normally interrupted at two points; namely, switch. 75 and contact members 72-74. Said c suit is closed at 7274 everytime shaft 34 is operated, but the heating means will not be energized unless switch 75 has previously been set in its circuit closing position.

It will be understood that the heating arrangement within thereceptacle 65 may be of any suitable type; for instance, the water may be caused to pass through coils interposed betweenpipe 66 andoutlet 67, said coils being exposed to the action of electric heating elements energized by the current passing through the circuit. Another uitable arrangement would be to have the water issue throughpipe 66 withinreceptacle 65 and to equip this receptacle with electric heaters of the immersion type.

The rubber tubing is preferably provided with reinforcing spiral wire shields at the points of bending, as indicated, for instance, in the drawings at 77.

It will be observed that no valves or other moving parts are interposed in the path of the cleansing fluid from its source of supply to the fluid delivery arm, so that no leakages are likely to take place.

It will also be observed that if any water should manage to leak through section 1-3, when COL.J pressed, the leakage would drip throughnozzle 25 and would be discharged directly into the closet bowl without splashing on. or causing any damage to the floor or any other part of the bathroom. The avoidance of all valves and other parts movable under the necessity oi maintaining water-tight connections also results in an extreme simplification of the mechanism as a whole, so that its cost of production is accordingly very much reduced.

Several parts of the mechanism so far described are movable in a vertical plane and, therefore, make it necessary to provide cavities in the underside of the seat, as explained. In the majority of cases it is desirable to apply the apparatus directly onto the underside of an existing seat, and this should be done with an expenditure of a minimum quantity of labor.

I have, therefore, devised another type of mechanism also embodying my invention where all the parts are movable in a horizontal plane so that tr e shallow chamber formed by the casing is sufficient of itself to house the same at all times.

Such an improved type of mechanism is illustrated in Figs. l2, 13 of the drawings. In the same 78 designates a relatively shallow casing, which can be red onto the underside of the seat by means of screws at 79, 30, forming therewith ashallow chamber 81. The operating member is a crank lever 82, mounted on a vertical pivot 83, said lever having an operating arm 8-1 projecting sidewise or" the seat to whichfluid delivery arm 86 is carried by a bracket 87, mounted on aninclined pivot 88, and made to communicate with an inlet tube 89, to which is connected thedelivery end 90 of a rubber tube 91, attached at the other end to a source of fluid supply such as, for instance, the water supply system. Said rubber tube enters the shallow casing at th rear at 92 and is di wardly extending lug 99, which projects directf'.

ly in the path of arm of crank lever 82. Crank lever 82 is normally held in the position shown in full lines in Fig. 12 by aspring 100, attached at one end to a fixed point 101 and at the other end to arm 85 at 102. aradial extension 103, the outer end of which is formed with a cylindrical lug 104, having aslot 105 through which passes a rod 106. Said rod is attached at 107 to arm 85 and has at its other end ahead 108, causing aspring 109 to j exert pressure against a washer 110, bearing against the surface of cylindrical lug 104. Said rod 106 also carries a collar 111, bearing against the opposite side of lug 104.

Whenarm 84 of the operating lever is moved in a counterclockwise direction from the position shown in full lines in Fig. 12 to the positlon shown in dotted lines at 84', the fluid delivery arm is caused by rod 106 to move to its operative position, shown in dotted lines at 36, its movement being effected by virtue of the pressure exerted by washer 110 against cylindrical lug 104.

When the fluid delivery arm reaches its operative position it is restrained from going any Bracket 87 is formed with L].-

fartherbecause bracket 8 strikes edge 112 -:Of rib portion .113ofca'sing 78. At this point arm :85 of operating lever 82 is about to strike against lug 1990f arm 9'7, and upon continued movement ofarm 84 in the same direction, arm 85 will actually bear against lug 99 and cause a certain angular displacement ofcrank lever 95 in a clockwise direction, thereby relieving the pressure exerted by end 93 of arm 1914 against the rubberttube. This free movement of the operating lever is made possible by the yielding connection provided byspring 109 between rod 166 and 193 of bracket 87, as will be understood.

The mechanism operates, therefore, in a manner analogous to that previously described, the fluid delivery arm being first brought to position and cleansing fluid being then permitted to flow through the rubber tube leading to the fluid de livery .arm. As soon as pressure againstarm 84 is relieved,spring 100 will automatically return the operating lever to its normalposition, collar lll bearing against cylindricallug 1-04 and in its turn causing the fluid delivery arm to resume its normal position shown. At thesame time spring 98 will also automatically returnlever 95 to its normal position, where end .93 ofarm 94 checks the flow of fluid through tube 91.

It is obvious that casing 7.8 may be made with or without a hinge attachment for the seat, being without said hinge attachment when it is designed for use in connection with a seat already mounted in position on its own hinges.

From the foregoing it will be seen that I pro vide an entirely new type of sanitary attachment for closets and bidets, which is free from the many objectionable featurescharacterizing other kindred devices heretofore in use.

It is obvious that the various constructional details of my device may vary from those shown without departure from the inventive idea; the drawings, therefore, should be understood as being intended for illustrative purposes only and not in a limiting sense.

I, accordingly, reserve the right to carry my invention into practice in all those ways and manners which may enter, fairly, into the scope of the appended claims.
