Abstract: A washer combination for a fastener driver includes a layer having a number of washer members coupled together and located side by side, and an elongate adhesive member or an elongate strap attached to the washer members for temporarily securing or coupling the washer members together, and for allowing the washer members to be selectively received or engaged with the nails or staples or fasteners that are hammered or punched out of the nose portion of the driver body member by the ejector. The washer members each include an orifice for selectively receiving or engaging with the nails or staples or fasteners. The washer members are selectively coupled together with hinge lines.

Abstract: A washer device for a fastener driver includes a layer having a number of washer members coupled together and located side by side, and having a hinge line formed between every two adjacent washer members for temporarily securing or coupling the washer members together, and for allowing the washer members to be selectively received or engaged with the nails or staples or fasteners that are hammered or punched out of the nose portion of the driver body member by the ejector. The washer members each include an orifice for selectively receiving or engaging with the nails or staples or fasteners, and one or more projections for separating the two superposed layers from each other.

Abstract: A fastener driver includes a driver body member having a cassette for accommodating staples, and a washer carrying device having a housing attached to the driver body member, and the housing includes a chamber for receiving washers, a mouth piece attached to the housing and having an opening formed in the mouth piece and aligned with the nose portion of the driver body member for selectively receiving the washers, and a pushing device slidably attached to the housing for moving the washers toward the mouth piece and the nose section of the fastener driver and for allowing the washers to be suitably engaged with the nails or fasteners that are hammered or driven by the ejector.
