Abstract: An improved electromechanical assembly advances a tubular protective covering around a toilet seat. The covering is stored on a reel, and pulled off from the reel as it is replaced, and the used covering is taken up on a second reel. An activation button exposed through the top of the assembly is depressed to actuate a switch assembly which, in turn, actuates a drive mechanism. By actuating the drive mechanism, the cover is moved through a predetermined distance in such a manner that when it is in the mounted position, the toilet seat body is completely surrounded by the tubular cover. An upper housing portion has an integral pressure blade for exerting a constant downward force on the advancing protective covering. The pressure ensures adequate contact between the covering and a counter shaft assembly which communicates magnetically with internal electronic circuitry.
