Abstract: A female connector has a folded pair of arms with a pair of juxtaposed slots apposed to a pair of perpendicular arms form the same spine. The arms flex to blade open width when molded into a receptacle. The arms are strong and resilient and flex free of the molding plastic. In cold temperatures there is only a small surface contact between the arms and the molded plastic allowing the arms to flex to receive blades unimpeded by the plastic. An extension cord for outdoor use with the female connector can receive 15 amp or 20 amp plug blades in temperatures at least as low as -10.degree. C.

Abstract: A housing for female receptacles in a molded female receptacle plug has a body and cover to receive female receptacle connectors. The housing is a premold for the receptacle plug. Female receptacles may be engaged in the housing and simultaneously crimped to wires in a cord set. The body and cover are interengagable. They can be snap fit or slide fitted together with female receptacle crimp ends on necks extending through the housing safe from mold plastic flashing in molding, when load bars are conventionally engaged into blade openings in the housing. The assembly of the housing and female receptacle is automatable with labor and material economies obtained in the molding and from automatable assembly and simultaneous crimpability of the engaged female receptacles.

Abstract: A stamped metal female blade receptacle is three sided, having a longitudinal opening. There is a flat side and curved side. The metal is resilient so that the curved side releases from the plastic when molded into a plug. In a plug, the receptacle is supported against unwanted flexure and biased against a received blade, providing full surface contact on one side of the receptacle. The sides of the receptacle do not fatigue in use. The receptacle is economical of metal and adapted for automated crimping. The structure of the receptacle enables one size receptacle to serve blades of various widths and thicknesses.The receptacles can be provided, integral on a stamping strip and alternately folded over, to be parallel to each other for machine crimping.

Abstract: The present invention is a metal blade formed of folded strips (13, 14) for an assembly of electrically conductive contacts in a printed circuit board, adapted to access line current, such as in a 120 V AC outlet. The assembly may be used in various ways such as an intermediate in the making of molded plugs. The blades are adapted for fabrication in a progressive stamping operation and for automation in use from a roll or hopper. A blade of the present invention has resilient tabs (21) and spaced away sharp edge fingers (16). The tabs are formed to snap engage in a tapered slot (26) in a printed circuit board with the sharp edges (17) of the fingers (16) in electrical contact with a printed circuit and to hold its engagement even before being soldered. Each of the folded strips includes pad (12) and a section of a bubble (15) formed to prevent flashing of plastic during a molding process.

Abstract: A two frame sofa bed recliner has a seat frame and back frame. The frames are elevated from the floor on supports. The frame ends are linked, overlapped, interengaging the seat frame with the back frame, enabling a simple conversion reconversion process from sofa bed to recliner. In recliner position the back frame tilts rearward on its end. The back frame is interlocked with the seat frame locked by a detent, retaining means and a second detent in a guide. Conversion and reconversion are effected by rotating the interlocked unit on to the back frame supports, disengaging the seat frame and back frame, then lowering the seat frame to the floor on the supports and interlocking the frames. For reconversion the process is reversed. A removable arm rest is attachable.

Abstract: A multi-station stamped metal conductor in a multi-outlet receptacle enables the simplified molding of the receptacle with less parts and wire connections.
