Abstract: A spectacle washer including a washing tub of a generally rectangular shape and a vibrator of not ultrasonic but mechanical type. The washing tub is formed at one of its longer side walls with a nose-shaped bulge which bulges thereinto and extends along the vertical center line of that particular side wall. The bottom wall of the washing tub is partially raised to form a raised bottom which extends around that center line and merging into the nose-shaped bulge. This raised bottom is shaped and sized to allow both the lower portions of the paired rims and the paired nose pads of a pair of spectacles to stably rest thereon, while one of the sides of the spectacles being placed on that portion of the bottom wall, which is left unraised. The mechanical vibrator is equipped with an electric motor and an eccentric weight. The electric motor has its vertical shaft of rotation positioned in the vertical center plane, in which the afore-mentioned center line extends.

Abstract: The apparatus comprises a throttle valve comprising an upper cylindrical resilient deformable membrane having an upper flange at the upper end thereof and a lower cylindrical resilient deformable membrane having a lower flange at the lower end thereof and connected at its upper end to the lower end of the upper cylindrical membrane by a central flange. The upper flange is secured to the upper wall portion of the outer wall of the apparatus and the lower flange is secured to the lower wall portion of the outer wall with either one of the upper and lower cylindrical membranes being twisted by 180.degree. about its longitudinal axis so that the twisted membrane is closed. The upper end of the throttle valve is attached to the hole discharge of the lavatory bowl while the lower end is located above the excrement reservoir.
