Abstract: 647,595. Chemical sanitary closets. EVERCLEAN, Ltd. Feb. 14, 1949, No. 949/48. [Class 26] A chemical sanitary closet of the kind comprising a tank a adapted to contain a sterilizing or digesting solution and a pivotally mounted faecal receiver having a receiving surface normally immersed in the solution, the receiver being operably associated with a seat q so that it is brought into the receiving position by the weight of a user and returns to the inoperative position when not so loaded, is characterized by a pair of rotatably mounted members b<SP>1</SP>, c<SP>1</SP> to form the faecal receiver mounted so that their receiving surfaces turn in opposite directions in passing from the receiving position to the inoperative position. The members b<SP>1</SP>, c<SP>1</SP> are mounted on spindles b, c pivoted in the side walls of the tank, and means connecting the said seat q to the said members for turning the latter comprise a stud k<SP>2</SP>, (on which the seat rests), attached to an arm k<SP>1</SP> inside the tank which actuates a toothed double quadrant i by way of an arm k attached to the quadrant i by a link m, one arm of the quadrant i engaging a pinion b<SP>3</SP> and the other arm an idle pinion meshing with a pinion c<SP>3</SP>, the rotaton of which pinions reverses the mem-. bers b<SP>1</SP>, c<SP>1</SP> to bring their flat faces b<SP>2</SP>, c<SP>2</SP> above the solution in the receiving position. On vacation of the seat q, the reaction of a spring p returns the lever k and rotates the spindles b, c to return the members b<SP>1</SP>, e<SP>1</SP> to their normal positions (Fig. 2). A bracket h carries the double quadrant i and a pulley n for a cable o, one end of which cable is attached to the outer arm k and the other end to the spring p and also a pinion j. The stud k<SP>2</SP> extends through a slot g<SP>1</SP> in a sideplate g, said stud k<SP>2</SP> being depressed to actuate the arm k<SP>1</SP>, the plate g being one of two opposite plates which, with plates e, f and the members b<SP>1</SP>, c<SP>1</SP> form a receiving compartment as a removable unit. The tank a has a rear extension a<SP>1</SP> in which is secured an outlet member a<SP>2</SP>, means for maintaining the solution at a predetermined level being a removable overflow unit located at its lower end in the outlet a<SP>2</SP>. Said overflow unit comprises tubes r, r<SP>1</SP> attached to a disc r<SP>2</SP> to which a rubber .sealing disc r<SP>6</SP> is secured by a plate and bolt. The tube r<SP>1</SP> has holes r', the upper end of it being of the same height as the solution level d. On the said upper end is slidably mounted a collar s having claws s<SP>1</SP> and diametrically across it is a bar t, having flats t<SP>1</SP> at its ends, said claws s<SP>1</SP> being engaged below a flange ring r on the tube r<SP>1</SP> to hold the collar slidably on. The bar t is clamped by a screw t<SP>2</SP> having, a wing head t<SP>3</SP>, the lower end of the screw engaging a notch r<SP>9</SP> in a crossbar. Footrests on which the user stands may be provided on either side of the opening, the depression of which footrests turns the rotating members forming the faecal receiver.
