Figs; 2 to 6 are on an enlarged lscale as .Referinglto the drawing. I2 `is the lavatory i bowl, the same having a marginal flange or rim AIlland an upstanding member I4 at the rear for attachment to a wail or other support.` Centrally positioned infront of `saidmoznloorand at the rear of the `bowl proper is a rectangularly-shaped protuberance I5 forminga housing, for a purpose to be described.` `All of these parts are preferably formed of a single, integral casting or stamping which, for sanitation, is preferably coated with enamel;V or "these partamay be of earthenware suitably glazed.. 1 t j `At one point, preferably in thefront, as shown,

the rim I3-of the bowl is `provided with a deep `notch or depression I6 which is adapted to receive the nape of the-neck ci.V the `patient as she sits orreclines before it with her'head in or over the l bowl.)l -Inits lowest part,V the bowl is provided wardlyextending ange I1,\asbest seen in Fig. 3.

The aperture and ange are preferably circular in outline. Surroundingthe aperture ,the bowlis preferably beveled, as: at I8.4 Fitted within the aperture andextending forsome distance below the LbowLisa drainmember I9, the upplend of which is y provided with an outwardly-turned Vi'iangewhichrests upon the bevel IBand forms a `water-gtiglit joint therewith. (At its lo'wer end, the member-119 istapered inwardly and is suitably connected with-the drain-pipe 20. Within the interior of the member I9 is a pair of nested cup- ,like members 2| `and 22,` thesamebeing spaced -to providea ycup-shaped chamber 23. Both therefore, an eifective trap.

of said members are provided with outstanding beveled flanges at their upper edges which rest one upon the other while the iiange of the outer member rests upon the fiange of the drain member I9. The inner member 22 is provided with a plurality of small perforations 24 in its bottom. The bottom of the outer member 2I is imperforate, but a row of perforations 25 extends about and through its side walls some distance above the bottom of the inner member. The water iiowing from the bowl is thus forced to rise within the outer member before it can pass through the perforations 25, and any hair or other matter carried by the water is trapped within the. member 22 or within the space 23 between the members. The members are not xed in position and can bereadily lifted out, to clear away the hair or other accumulated matter. The structure is.

Leading from the rear into the housing I5 is a pair of supply pipes for the hot and cold water respectively. One of these pipes,` say the hot-water pipe, is shown at 26 in Fig. 1. The other pipe is shown at 21 in Fig. 4. Of course, it is immaterial which is the hot-water pipe. At their forward ends, these pipes are connected with a manifold or mixer 28. The ilow of the water through these pipes is controlled by valves;

the stems of which project through the upper wall of the housing I5 and are provided with suitable hand grips or levers 29 and 30 respectively. The water for the washing operation is discharged from the mixer forwardly through a down-turned spout 3l in front of the housing and above the bowl. In the connections between the mixer and the spout is a valve which is normally closed but is adapted to be opened by the water as it iiows toward the spout. Any suitable connections and valve may be employed, that shown comprising a nipple 32 which is threaded into the mixer 28 and projects through the front wall of. the housing, the spout being screwed onto the nipple, suitable nuts 33 holding the nipple in place. The forward end of the nipple is provided with a seat for a valve 34 which may be a ball, as shown, or any other suitably shaped valve member which ts upon said seat. That part of the spout which surrounds thel valve is bored or cored to receive a helical spring 35 which is compressed between the valve and an internal shoulder 36 within the spout. The vspring is relatively weak so that a comparatively slight waterpressure is suiiicient to open the valve. The valve itself may be formed of any suitable material.

Connected with the mixer or manifold between the supply pipes 26 and 21 is a flexible pipe 31 which is looped downwardly and is then extended upwardly through'an aperture 38 in the upper part of the member I4, the pipe being provided with a ball-like enlargement 39 to hold the pipe in the looped formation shown in Fig. 4. At its upper or outer end the pipe is provided with a spray-head 40, the ow of the water to it being controlled by any suitable hand-operated valve, as indicated at 4I.

To hold `the flexible pipe taut and to pull it back-after it has ,been extended, as will be more fully explained, I provide a mobilev weight in the form of. a sheave 42, the same having a deep peripheral groove midway between its ends in which the loop o! the pipe reposes. the sheave are parallel and fit between the side walls of a well or casing 43 so as to be guided by said walls and be prevented from turning lateral- 'I'he ends of ly; for if the sheave were permitted so to turn, the vertical portions of the pipe would wrap about each other and prevent or limit the outward movement of the pipe. The deep groove in the sheave holds the pipe centrally positioned in the well 43 and holds it out of contact with the guide walls of the well. The well may be attached to any conveniently-positioned part of. the apparatus, as by a bracket 44 which is fastened to the well and the'housing I5.

As will be seen in Fig. 1, the rim of the bowl is approximately rectangular in plan, the side edges being substantially perpendicular to the attaching member I4. This provides a at, horizontal surface, 45, at each side of the housing I5 upon which to place soap, glasses or other articles which may be employed.

The operation may be briefly described as follows: The valves at 29 and 30 having been'respectively adjusted until the eiiluent water at the spout is of the desired temperature the patient vsits or reclines in front of the bowl with the nape of her neck in the notch I6 and her head over the bowl. Her hair is then thoroughly washed. During this operation, the valve 4I at the spray-head is closed, and the water opens and passes the valve 34 and flows through the spout'3I. Usually, soaps or other toilet preparations which create a lather, are employed so that it is necessary that the hair be thoroughly rinsed. The operator thereupon graspsthe spray-head, pulls it upwardly and forwardly to its proper spraying position and opens the valve 4I. That relieves the pressure` upon-the valve 34 and allows it to close, thus diverting all the water to the spray-head. Havingfthoroughly rinsed the hair, all valves are closed and the sheave-weight is permitted to pull the flexible pipe back into its normal position. Finally, the trap members 2I and 22 may be removed, if need be, cleaned and returned to'their normal positions. after which the apparatus is ready for' another patient.

As will be noted rfrom Fig. 4, the diameter of the sheave 42 is shcrter than the transverse dimansion of the guide casing 43. This not only permits the sheave to enter the casing but prevents the jamming of the iiexible pipe 31 between the sheave and casing.

If the flexible pipe were drawn out too far it would be bent abruptly at its connection with the manifold or mixer and would be liable to be pulled loose or to start a leak at that point. To prevent that possible result, I prefer to provide a readily removable stop. which may be attached to the guide casing to project into the path of the sheave to arrest it before the pipe is thus abruptly bent.

While the invention as described is particularly designed for use in washing and rinsing the hair, it is obvious that, with slight modification, it is adapted for other uses. For example, it maybe used as a kitchen sink, or as an attachment for a kitchen sink, wherein dishes are washed and sprayed. In that case, the notch I6 would not be needed or desirable; but otherwise the structure and operation would be substantially as shown and described.

Having thus described my invention, I claim:
