    Improvements in and connected with Lavatories and like Washing Apparatus. tlie ovei-ilow jmssage, GS and in some cases the overflow passage may be one not leading into the waste pipe (B'^) but discharging into a gutter below (not shown). In the modiiioations shown in Figures., 11, 12, and 13, whkdi are vertical sections, the discharge orifice, C, is in the bottom of the back of the basin, A, the valve, closing towards the basin. In Figure, 11, the valve, C^, is on the 5 lower end of a ouiwed rod, H, fitted to slide on a stud, n*, the upper end of the rod having a pin, ]'i'\ which engages in a'i notch in, a catch plate, H^, fixed to the basin. A, to keep the valve shut, and when the pin, E'^, is freed from the notch and the curved rod, H, drawn up the valve, C^, is moved away from its seat. In this position the valve is held open by the pin, E^, engaging with lo a second notch, H^, in the catch plate,, H^. As shown in Figure, 12, the valve, G^, is made with a spindle, J, projecting out from its back to which sj^indle a bellcrank, J^, and treadle, J^, are attached and the valve is kept shut by the weight of the treadle, anid connections and is opened by raising it. Instead of the treadle, J^, a handled rod, J^, shown [5 by dotted lines may be attached to the bellcrank, J^, for actua.ting the valve, C^. In Figure, 13, the end of the valve spindle, J, has fixed on it a small piston, K, working in a cylinder, K^, to one end of which water under pressure has access through a pipe, Iv^, and acting on the piston,, |K, tends to keep the valve, C^, shut. A handled lever, K^, is centered in a bracket, K^, and its lower end passes 20 through a slot in the valve spindle, J, so that on moving the lever, the valve, Cb can be opened against the pressure of the water, the pressure closing it on the handle being let go. My invention comprises also improved water supply fittings for the lavatory, of which two modifications are shown on Sheet Two of the drawings. Figures, 14, 25 and 15, being front and side elevations partly in section of one modification; and Figure, IG being a perspective view of a second modification. As shown in f igures, 14, and 15, a metal box, L, has connected to its under¬ side hoit-water and cold-water supply pipes. Lb lA, to. which are applied screw- down valves, L'b L'*', the handled spindles, L^, L®, of which extend upwards 30 through the stuffing boxes, L', L®. In the middle of the box, L, there is a conical seating, M, preferably of wide angle for a plug, Mb formed at the bottom of a short hollow column, M^, and having two ways, M®, M^, in it, of which one, M^, is for communicating with a spout, M^, delivering into the basin (not shown) whilst the other, M®, is for communicating with the interior of the 35 column, M^. Either communication is open according to the position of the column, M^, the other being then shut. In the drawings the way, M^, is shown open and communicating with the spout, M®, the oitlier way, kP beinjg shut. The top of the column, Mb has attached to it by 'a horizontal swivelling plug joint, N', having a way, .Nb through it, a cuiwed / pipe, which at its outer 49 end has hxed to it a hollow conical plug, A®,, preferably of wide angle, and formed with two sets of ports, P^, P^. There is fitted do turn on the plug, X®, a conical socket or seat, P®, fonned in the interior of a bell-shaped piece, P^, having fixed to it a central noizzle, Q, and a perforated plate, Q.b In one position of the bell, P^, as shown, the central nozzle, Q, receives water through the 45 plug, Xb and in another position the water has access to the perforated plate, Qh When the column, Mb is turned with the curved ])i])e, X^, to the back, as shown, water is delivered into the basin (A) through the spout, M®, but when the column, M^, is turned to bring the cuiwed pipe, X^, foiwards water has access through the column and pipe to the bell, P^, and by adjusting the bell, as de- 50 scribed, can be made to issue as a central stream or douche or as a shower. The curved pipe, Xb can be turned in the top of the column, Mb so as to place the bell, P'^, in a vertical, horizontal or inclined position. For only a cold water or single water supply tlie parts may be simplifitHl. As shown in Figure, IG, separate stop valves, IP, are used, giving oommunica- 55 tion, one to the basin spout, M'b and the other to the curved arm, X^.
