Abstract:
The instant invention discloses a receptacle where the surface of the face along its width is flat in one plane and along its length has a constant radius. The shape of the face of the receptacle allows for the proper seating of an inserted plug. The receptacle is adapter to be located in a wall plate having a vertical axis of positive first differential and zero second differential, comprised of a combination of splines drawn between points of varying distance from a datum plane and zero second differential when the rate of height increase of individual splines is constant. The receptacle can be placed next to a switch, the front face of which follows the shape of the wall plate.
Abstract:
There is disclosed structure which overcomes the difficulties encountered with respect to mounting wiring devices such as a receptacle and/or a switch to a box and then attaching a wall plate. Some of the difficulties encountered are positioning the wiring devices to be in alignment with each other, locating the wiring devices to be parallel to each other, adjusting the spacing between the different devices to be equal and uniform and fixing all of the devices to be flat against the wall. These deficiencies are overcome by an alignment plate having a single centrally located opening sized to receive one of more wiring devices and a set of alignment pins for each wiring device. Each set of alignment pins on the alignment plate is located on a vertical axis which defines the center for a wiring device and each wiring device has openings for frictionally receiving and holding captive a set of alignment pins. The alignment pins accurately position, align and locate all of the wiring devices relative to each other. Thereafter the alignment plate and the wiring devices can attached to a box by means of mounting screws and a wall plate can then be positioned around the wiring devices without further adjustment.

The instant invention discloses a receptacle having a shape along the width of its face that is flat in one plane and along its length that has a constant radius. The shape of the face of the receptacle allows for the proper seating of an inserted plug. The shape of a wall plate around the receptacle along a section which runs along its vertical axis defines a surface of positive first differential and zero second differential, comprised of a combination of splines drawn between points of varying distance from a datum plane. The surface has zero second differential when the rate of height increase of individual splines is constant. When ganged with a switch, the front surface of the switch follows the shape of the cover plate.
Abstract:
The instant invention overcomes the difficulties encountered with respect to mounting electrical wiring devices to a common box and then positioning the devices relative to each other prior to attaching a wall plate. Some of the difficulties encountered are positioning the wiring devices to be in alignment with each other, locating the wiring devices to be parallel to each other, adjusting the spacing between the different devices to be equal and uniform and fixing all of the devices to be flat against the wall. In the prior art, the wiring devices are first loosely attached to a box and then moved back and forth, and up and down to fit within cut outs in a wall plate which is then attached to the wiring devices with screws. A time consuming and tedious job. This invention overcomes these deficiencies by providing wiring devices that have locating openings for engaging alignment pins located on a plate that is subsequently attached to a box. The alignment pins, when engaged by the close clearance locating openings, accurately positions the wiring devices to allow a wall plate to be place around the wiring devices without requiring any initial or subsequent adjustment. Each set of alignment pins on the alignment plate can be located on a vertical axis which accurately defines the center for the wiring device. The opening in the wiring device receives and holds captive a set of alignment pins. The alignment pins accurately position, align and locate all of the wiring devices mounted to the attachment plate, and the plate allows the wiring devices to be positioned against a flat surface. Thereafter, a wall plate can be positioned around the wiring devices without requiring any adjustment.

Abstract:
There is disclosed a wall plate with a single opening for receiving one or a gang of wiring devices within the single opening. The wall plate has along its vertical axis, a surface of positive first differential and zero second differential, comprised of a combination of splines drawn between points of varying distance from a datum plane. The surface has zero second differential when the rate of height increase of individual splines is constant. The wall plate, when composed of non-conducting material, has a conductive coating on its front surface, on its back surface or on both its front and back surfaces. When the wiring device is a switch, the surface of the switch face follows that of the wall plate. When the wiring device is a receptacle, the surface along the receptacle face is flat in one plane to allow for the proper seating of an inserted plug.
