Purser ABSTRACT: A ceiling box junction plate for making up the wiring in ceiling or light junction boxes, the device comprising an assembly including a plurality of connector openings, a pair of the connector openings being enjoined by a connection for extra wire capacity for ground wires, a connection to a standard female outlet receptacle, and a connection for hot lines from a wall switch to actuate a light.
CEILING BOX JUNCTION PLATE This invention relates generally to electrical connection boxes. More specifically, it relates to a ceiling box junction plate.
A principle object of the present invention is to provide a ceiling box junction plate that is used in house and building wiring, for making up the wiring in'ceiling or light junction boxes.
Another object of the present invention is to provide a ceiling box junction plate having the advantage of being quickly and easily assembled.
Another object of the present invention is to provide a ceiling box junction plate having means to add-or remove wires quickly and easily.
Another object of the present invention is to provide a ceiling box junction plate wherein after the ceiling box junction plate has been installed, the light fixture could be quickly and easily installed by anyone by just plugging in the previously installed plug on the fixture.
Still a further object is to provide'a ceiling box junction plate wherein by putting in two mounting screws, the fixture could be changed easily or even removed or left off without an unsightly opening in the ceiling.
Other objects of the present invention are to provide a ceiling box junction plate which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.
These and other objects will be readily evident upon a study of the following specification and accompanying drawing wherein:
FIG. 1 is a top plan view of the present invention,
FIG. 2 is a side elevation view thereof,
FIG. 3 is a bottom view thereof, and
FIG. 4 is a top plan view thereof shown wired in an electric circuit.
Referring now to the drawing in detail, the reference numeral represents a ceiling box junction plate, according to the present invention, wherein there is a plate 11 of circular configuration, the plate being provided with a plurality of openings upon the upper side 12 thereof, the openings being arranged in a circular concentric with circular plate 11. Several of these openings defined with the reference numeral 13 are for the purpose of making up hot lines. Another two of these openings defined with the reference numeral 14 are for the purpose of making up ground wires.
The openings 14 are enjoined by a common connection 15, as shown in FIG. 1 of the drawing. One of the openings 14 is connected by a connection 16 to a prong receptacle 17 of a standard female outlet 18. Oneof the openings 13 is connected by a connection 19 to the other receptacle 20 of the standard female outlet 18.
- openings 22, spaced also diametrically apart and adjacent to the screw openings 21, are for the purpose of mounting the light fixture. Other fixtures than a light fixture may be mounted by the screw openings 22. The screws received in screw openings 21 serve to mount the plate 11 to the box.
In FIG. 4 of the drawing one hook up 23 is shown which is very much simplified with the use of the present junction plate 10. The hook up is shown to include a pair of three-way switches 24 and 25, each of which is connected by a white wire connector 26, a red wire connector 27 and a black wire connector 28. The red and white wire connectors for both three-way switches go to common openings 13, whereas the black wire connectors go to different openings 13. An incoming hot line 29 is connected to opening 13 which is also connected by black wire 28 to the three-way switch 25 and by means of connector 30 to an outgoing hot line. An incoming ground line 31 is connected to opening 14, and a connector 32 is connected to the other opening 14, the connector 32 going to the outgoin ground line.
Thus there as been shown a hook up which may be made rapidly and which comprises a neat job.
A knockout opening 33 is centrally positioned upon the junction plate, the knockout opening being provided for mounting of heavy fixtures on the fixture stud in the ceiling box.
While various changes may be made in the detailed con-- struction, it is understood that such changes will be within the spirit and scope of the present invention as is defined by the appended claims.
lclaim:
1. In a ceiling box junction plate, the combination of a circular assembly, said assembly including a junction plate, said plate having a circular peripheral edge, said plate having an upper and lower side, said plate upon its upper side being provided with mounting openings, said openings comprising a plurality of openings in a pattern that is concentric with said plate, several of said openings comprising means for making up hot lines, while a pair of said openings serve for making up ground wires, one of said openings for making up ground wires being connected by a connector to one receptacle of a standard female outlet, and one of said openings for making up hot lines being connected by a connector to the other receptacle of said standard female outlet, said plate including a central knockout opening provided for mounting of heavy fixtures on the fixture stud in the ceiling box, a pair of diametrically spaced apart screw openings being provided for mounting said plate to said box, another pair of diametrically spaced apart screw openings being provided for mounting light fixtures or other fixtures, and both said pairs of screw openings being located along a singular, common diameter.
