  • Patent number: 4746176
    Abstract: The towel dispenser adapted to store and supply a towel of undeterminate length. At least one of the unused and used portions of the towel is stored in the form of a roll on a shaft. The towel dispenser includes a pair of side walls each having at least one elongated hole. The portion of the side wall defining the inner peripheral edge of the elongated hole is obliquely bent towards each respective other side wall so as to form a tab projecting towards the other side wall. Each end of the shaft is rotatably and slidably received in the respective elongated hole defined by the respective tab, in such a manner that each end of the shaft does not project beyond the plane of the associated side wall.

  • Patent number: 4360130
    Abstract: The wall-mounted dispenser for liquid soap has a separable reservoir with an outlet valve. The dispenser further includes a main body with a second outlet valve. When the reservoir is mounted to the main body, a metering chamber is defined between the two outlet valves. The dispensing function is experienced by pushing in a plunger which temporarily decreases the chamber volume and forces the main body outlet valve to open temporarily, thus dispensing a charge of liquid soap. As the plunger is released, a spring return pushes the plunger out, decreasing pressure in the metering chamber, which is equalized as the first outlet valve temporarily opens, admitting a next charge of liquid soap from the reservoir to the metering chamber. The reservoir is replaced by pushing in a resilient release, but the resilient release is preferably normally provided with a stop which must first be moved out of the way.
