ELECTRICAL FIXTURE May 30, 1944.
Filed April 3, 1942 1/522 /02" 1. flzzcz ersazz Patented May 30, 1944 UNITED STATES PATENT OFFICE 2 Claims.
This invention relates generally to electrical fixtures and in particular to an electrical fixture of pendent type.
Electrical fixtures are well known in the prior art for suspending an electrical unit from a conduit box or like structure having a hook and an electric socket or receptacle thereon. The fixture is provided with a supporting portion adapted for connection with the hook and also carries a plug extension for insertion in the receptacle. In some of the prior art fixtures the switch mechanism for controlling the operation of the electrical unit is assembled with the conduit body so that the operating lever therefor extends outwardly from one side of the conduit box. Where installations require the conduit box being located entirely above an opening in the ceiling or sup porting wall the operating lever is generally inaccessible so that the usual pull chain operatively associated therewith must be extended through a separate opening in the supporting Wall. This of course is objectionable from an appearance standpoint and further is generally inconvenient due to the chain frequently catching on the sides of the opening therefor. art fixtures the switch mechanism is assembled as a part of the electrical unit and is located in a position immediately above the unit. This construction is particularly objectionable where the electrical unit may be of considerable bulk, such as in the usual electric light reflector assemblies, due to the pull chain overlying a portion of the reflector and then dropping vertically therefrom. Thus on operation of the switch mechanism the pull chain usually becomes entangled with the reflector so that the vertical hanging portion of the chain must be lifted and extended in a somewhat longitudinal direction to operate the lever. Along with these inconveniences there is the further inconvenience of the electrical fixture being excessively rocked each time the operating lever is actuated.
It is an object of this invention, therefore to provide an improved electrical fixture.
Another object of this invention is to provide a switch unit adapted to be suspended from oneend and attachable with an electrical unit at the opposite end thereof.
A further object of this invention is to provide a pendent electrical fixture including a switch mechanism adapted to be operated freely without interference from any portion of the electrical fixture or the fixture supporting structure.
A feature of this invention is found in the provision of a preassembled pendent switch unit which is simple and rugged in construction, adapted to be readily and quickly assembled in mechanical and electrical connection with an electrical unit, and having an eye portion at one In other of the prior end for suspension purposes to provide in all a complete pendent fixture.
Another feature of this invention is found in the provision of a fitting for receiving a switch mechanism therein adapted to be suspended from end and attached with an electrical unit at its opposite end, with the wires electrically connecting the switch mechanism and electrical unit being extended through the fitting in a substantially vertical direction and generally free of the switch mechanism.
Further objects, features, and advantages of this invention will become apparent from the following description when taken in connection with the accompanying drawing in which:
F1 g 1 is a view in perspective showing the complete assembly of the electrical fixture of this invention;
Fig. 2 is an elevational view of the electrical fixture in assembly with a conduit fitting; and
Fig. 3 is an exploded view in perspective of a pendent switch unit for the electrical fixture.
With reference to Figs. 1 and 2 of the drawing the electrical fixture is illustrated in assembly with an electric lighting unit l0 including a reflector. The improved fixture includes a body member H which is illustrated in Fig. 2 as a standard conduit box or fitting having conduits [2 leading thereto. The box H is supported entirely above an opening in a ceiling or wall por tion l3 with the lower side thereof, as viewed in Fig. 2, provided with a hook portion 14 and an electric receptacle or socket [6 located within the opening.-
The electrical unit It and body member H are connected together by means including a fitting having a housing I8 with an eye portion l1 formed at one end for connection with the hook portion l4 (Figs. 2 and 3). The body member I8 is shown as being of a substantially tubular shape and is provided intermediate the ends thereof with an enlarged portion 20 having a fiat open side 2! for receiving a switch mechanism l9 therein. It is to be understood of course that the housing may be of any other suitable shape. The switch mechanism [9 is of a preassembled type adapted to be carried in a cover 22 for closing the side 2|, and has an operating lever 23 projecting outwardly from the cover when the cover is in a closing position. The cover 22 at the support for the switch mechanism is bulged or raised outwardly so as to position the switch away from the housing wall 25. An open space is thus provided in the housing in a direction longitudinally thereof for a purpose to be later noted. The lever 23 is shown as being of a universal type connected with a usual ball chain 24. The lower end of the housing I 8, as viewed in Figs. 2 and 3, is internally threaded for threaded engagement with a conduit or tubular connecting member 26, the opposite end of which is attached to the electrical unit II) by threaded engagement therewith.
The switch mechanism I9 and the electrical unit III are electrically connected by conductor means, indicated at 30, carried within the housing I8 and tubular connecting member or conduit 26. As appears best in Fig. 2 the conductor means are extended in a substantially straight line through the connector 26 and the space provided in the housing I8 between the housing wall 25 and the switch mechanism I9 and includes a wire 21 extended outwardly through an opening in the upper end of the housing. I The wire 21 has an electric plug 28 thereon for insertion in the receptacle I6. It is seen, therefore, that the switch unit, including the switch 'mechanism I9 and housing I8, are releasably attachable at one end with the hook I4 and at the opposite end thereof with the electrical unit I 0. The conductor means 30 are easily accessible through the open side 2| for connection with the switch mechanism and readily positioned in the space provided therefor in the housing I8 on closing of such side by the cover 22.
From a consideration of the above description it is apparent that the conduit structure II and conduits I2 may be completely installed separately from the electrical fixture, with the box I I supported either entirely above the wall I3 or below such wall without in any way interfering with its assembly with the electrical fixture. Thus as is shown in Fig. 1 the hook I4 and receptacle I6 may be carried directly on the Wall I3 with the electrical connections I2 for the socket I6 being extended through the wall and suitably supported on the top or inside thereof. Since the operating lever 23. is included as a part of the pendent switch unit it is unnecessary to make any provision therefor in the electrical assembly on the wall I3.
It is to be noted further that the switch unit is supported directly at the hook If: so that any force applied on the chain 24 to operate the lever 23 is applied substantially at the pivotal support of the switch unit. A rocking of the electrical fixture during the operation of the lever 23 is thus practically eliminated. The operation of the lever 23 is further facilitated by virtue of the electrical unit I being spaced from the switch unit by the connector member 26 so that the chain 2 as is clearly shown in Fig. l, is adapted to hang in a substantially vertical direction to the outside of the electrical unit It]. The chain 24, therefore, when manipulated to operate the lever 23 is practically free of the electrical unit Ill so as to further eliminate any rocking action of the fixture.
By virtue of this assembly of the switch unit in the electrical fixture the complete fixture is capable of being entirely assembled separately from its associated hook I4 and receptacle I6. Its installationis a simple matter of merely connecting the eye I1 on the hook I4 and inserting the plug 28 within the receptacle I6. In many instances, such as in army barracks, auditoriums or the like a conduit box and associated hook I4 and socket I6 may be installed wherever light may be desired and the electrical fixtures can be attached thereto whenever required. The location of the conduit above the ceiling does not detract in any way from the appearance of the room while the detachment and suspension of the electrical fixtures is simply accomplished in a minimum of time,
The invention thus provides an improved electrical fixture including a detachable pendent switch assembly constructed and relatively assembled in the fixture so as to be easily connected electrically with the electrical unit and freely operated without interference with the fixture supporting structure or the suspended electrical unit.
Although the invention has been described with respect to a preferred embodiment thereof it is to be understood that modifications may be made therein which are within the full intended scope of the invention as defined in the appended claims.
