Improvements in and connected with Lavatories and like Washing Apparatus, I, John Shanks, f)f Tubal Works,, llarrliead, in the Coimty of Itenfrew, North Britain, SanitaiT Engineer, do hereby declare the nature of this invention to be as follows, that is to say: — My said invention comprises various improvements in and connected with lava- torieis and like washing apparatus, and has for its object increased conveniencei and other advantages in use, with economy in construction imd facility in fitting up, in cleaning and in repairing. A lavatory basin made and provided with a modification of my jjresent improve¬ ments, is preferably of earthenware and foimed with a flange or lugs at the back m to be cemented or built into a wall; and with the view of avoiding other fixtures to the wall, dovetail or other sockets are formed in the bottom of the basin piece to receive scre'W studs which are finnly fixed by a wedge action or othei'wise and which have hooks or brackets bolted to them to support pipes or other parts. The seat or port for the basin discharge valve is formed in the basin piece itself ^. and is of a conical form. In some modifications an internal discharge valve opens inwards or upwards; and in others the seat surface is external to the basin proper tile valve being applied externally. In one modification an internal heavy valve with a rubber flange is used and is covered by a grating up through the centre of which the spindle or handle of the valve passes. The grating is fixed by screws to bolts passing through holes made for them through the bottom of the basin, the discharge pipe made with a wide flange being fixed to them by screw nuts. In •inother modification a heavy internal valve having a rubber flange, is made with a hollow downward extension haring holes in its sides below the ruliber flange, the extension entering the discharge pipe which guides it. A bayonet slot formed in the hollow extension has projecting,into it a pin fixed through the discharge pipe, this pin holding the valve open when it has been raised and turned round a little. Instead of a separate fixed grating the upper part of tlie valve is made with star- like projections which serve as a grating. In another modification a vulcanite seating is fixed in the discharge opening of the basin, and the valve is made of or coated with vulcanite. Any of these discharge valve parts may be arranged in the bottom of an overflow passage or recess instead of being the bottom of the basin proper. An inclined metal grating is in some cases fixed at the to[) of the oveiflow passage in preference there being an opening through the'back of the basin proper; and in some cases the oveiflow passage is a short one not leading into the waste pipe but discharging into a gutter below. ° In the external-seat modifications the discharge orifice is in the bottom of the back of the basin, the valve closing towards the basin A \_Price 8c?.]
