Abstract
An improved stopper arrangement is provided, for use with a remote stopper actuating mechanism having a mechanical lever system for raising a central post to which the waste stopper is attached. The improved stopper has a central spindle to which is attached the circular stopper disc by means of which the waste is sealed. A set of guidance vanes located beneath the stopper disc and serving to center it in the waste aperture is separably secured by locking means to the actuating spindle in variable height relationship to the stopper mechanism independently of the stopper. Special cranked tools provide access to the locking means, to preclude vandalization.
Claims6
In combination with a washroom fixture having a waste pipe, a waste outlet within said fixture connected in liquid sealing relation with said waste pipe, a remote actuating mechanism extending within said waste pipe to a location beneath said waste outlet having a waste actuating post extending upwardly towards said waste outlet, a waste stopper having a disc portion to block said outlet when in a closed position, stopper post means interconnecting said disc portion in adjustable axially spaced relation with said waste actuating post, to provide selective upwards displacement of said disc in opening relation with said waste outlet upon actuation of said actuating mechanism, and threaded locking means securing said stopper post to said actuating post in locked relation therewith, said locking means being directly accessible solely through said waste outlet when said disc is in a raised condition, by way of a cranked tool, to preclude unauthorized tampering with said fixture, said actuating mechanism precluding upward withdrawal of said waste stopper from said waste outlet.
