Dispenser for hand towelling

Claim 1

A dispenser for a web of hand towelling comprising a housing receiving a supply of hand towelling, a dispensing roller over which the web of hand towelling can be withdrawn from said supply, a wind-up roller for drawing in and winding up used hand towelling, a timing mechanism including a timing stop member, a suction cup carried on said timing stop member, and a counter element for said suction cup, said timing stop member being movable from a rest position against a predetermined bias into an operative position by the withdrawal of hand towelling, in which latter position said suction cup adheres for a pre-set period of time against said counter element, a limiting device arranged for being held in an effective position by said timing stop member when the latter is in its operative position, said limiting device in said effective position being effective for blocking said dispensing roller for said pre-set period of time after a predetermined length of hand towelling has been dispensed, an electric motor arranged for driving said windup roller, and means for switching said electric motor into operation by the movement of said timing stop member back into said rest position, a coupling operable by said timing stop member, for connecting said electric motor to said wind-up roller, said coupling only being engaged as long as said timing stop member is in its rest position, said wind-up roller being so disposed as to bear against the periphery of a roll of used hand towelling, said wind-up roller being connected to a coupling arrangement which can be shifted by said timing stop member to couple said windup roller with said electric motor for winding purposes, so long as said timing stop member is in its rest position, and to couple said wind-up roller with said dispensing roller for winding off hand towelling from said roll, so long as said timing stop member is in its operative position.
