Serial No. 385,057.
' lThis invention relates to improvements in lighting fixtures and refers more particularly to iixtures of the type adapted for use with multiple Street lighting systems.
Heretofore, it has been common practice to arrange the lamps of a multiple system of street lighting in sect-ions to be connected across the lines upon actuation of a section control switcl, which was governed by the energization and de-energization of a control wire; and as the section control switches carried the load ot a number of lamps, they were of necessity expensive and complicated in design.
lt is, therefore, an object oilthis invention to provide a street lighting lixture of the character described which has a contacter switch, to open and close its lamp circuit, incorporated therein. The provision of an individual contacter switch tor each lightingxture ot' a system, while increasing the number of con-' tactors used, makesY the installation of tixtures more convenient and permits a relatively cheaper construction for the contactors as they carry the load of only a single lamp. `With the above and other objects in View which will appear as the description proceeds. my invention resides in the novel construction, coi'nbination and arrangement ot parts substantially as hereinafterY described and more particularly deiined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope ot the claims.
In the accompanying drawings, I'have illustrated several Vcomplete examples of the physical embodiment of my invention constructed according to the best modes l have il so -far devised 'for the practical application ot the principles thereof, and in which:
Figure 1 is an elevational view of a lighting fixture embodying my invention with parts broken awayY and in section;
Figure 2 is a view similar to Figure 1 illustrat-ing a modified form of my invention;
Figure 3 is a diagrammatic view illustrating the electrical connection of the fixture and its application in a multiple lighting system, and
insulating plate or panel 18.
Figure 4 is a View similar to Figure 1 of another modified form of my invention.
Referring now more particularly to the accompanying drawings vin which like numer- Y.
ture, and the top ot which is provided with an internally threaded aperture 6, to .receive a suitable support, not shown.V A refractor 7 is connected with the lower periphery of the housing 5 to diffuse the light of a lamp 8 carried by a receptacle 9 supportedwithin the fixture by brackets 10.
The brackets 10 are substantially right angular and have their horizontal arms connected with the receptacle and their vertical arms fixed to the inner walls of the housing by bolts 11 or the like.
, Mounted within the housing 5 above the receptacle 9, is a' contactor comprising a solenoid 13 and an armature. 14 connected with a switch 15, byvwhich the lamp circuit is opened and closed. The solenoid 13 is wound about one arm 16 of a substantially U-shaped laminated core 17,`suspended from a basev plate 18 of suitable insulating material, the
base. plate 18 being secured to the adjacent walls of the housing by screws 19. y The other arm 20 ofthe core 17 has its outer laminations extended laterally and providedV with aligned apertures through which a pivot pin 21 extends to pivotallyy mount the armature 14 for movement toward and away from the pole piece formed by the core arm 1G. V
Current for the solenoid and the lamp 8 enters the `fixture through lead-in conductors 22, 23 and 24, whichpass through the opening `6 `in the top of the housing and through the supporting member, not shown, to be connected with supply lines25, 26 and l27 and a control wire 28, seeFigure 3; the
inner ends of thelead-in conductors 22, 23 and 24 being connected with terminal members 29, 30 and 31, respectively, carried by the The lead-in conductor 22 is connected with the line wire 27, and through its termina-l member 29 and a conductor 33, with the mov! able arm 32 ot" the switch 15 carried by the armature 14. It will be noted that the arm 32 extends beyond the pivot 21 and has its end direct-ed at an angle to engage the adjacent portion of the core and provide a yielding spring tension to urge the armature away trom the pole piece and maintain the switch normally closed. The stationary Contact 34 oi. the' switch '15 is connected with one side oit the lamp 8 through a conductor 35, one end et which connected with a terminal member 35 which also serves to secure the supporting arm of the stationary Contact to the panel 18.
.The other side of the lamp 8 is connected with the terminal member through a conductor 37 and through the lead-in wire 23, with the neutral or grounded wire 2G of the supply line, so that when the solenoid 1.3 is cle-energized the switch 15 closes and illuminates the lamp. Energization lof thesolenoid lattracts the armature 14 which opens the switch and breaks the lamp circuit. One sideA ot the solenoid is connected with the terminal member 8O by a conductor .38, and the other side thereot is connected with the terminal member 3l through a conductor 39 42, respectively, is closed.V The master control switch is preferably located at a remote central point land when. closed energizesl the entire control wire 2S and eitect-s the operation ol all solenoid switches :connected therewith. In this manner, failure of any single solenoid or lighting lixture does not in any way atl'ect the other fixtures connected with the controlwire.
In Figure 2 is illustrated a slightly modiled form ot my invention which diifers Vfrom that illustrated in Figure 1 in that the housing is not termed in one piece but is more on the order et' the conventional type of lixture. In this instancethe body, .whichis usually termed ot porcelain, is replaced by a metal housing 42:3 whose top is closed and irom one side of which an internally threaded boss 44 extends, to provide means tor attaching the v 1re te a suitable support, not shown.
nother feature of diiference in thismodii'ication., is the means for `adjusting the lamp receptacle 9 vertically within the housing. This V means consists ot substantially U shaped supporting members 45 iixed to the inner wall ot' the housing 43 at diametrical` ly opposite points and provided with aligned Aapertures through which adjusting screws 4G extend to be threaded. in armsi47v extended from the receptacle so that turning of the screws 46 raises `and lowers the' receptacle; the screws being held against longitudinal movement with respect to the supporting members 45 by nuts 48 pinned to the ends thereof. The refractor 7 in this form of the invention is provided with a suitable reflector hood 49.
In the modification illustrated in Figure 4, the contacter is mounted fithin a conventional porcelain housing 50, the top of which is provided with apertures 51 through which the lead-in conductors 22, 23 and 24 enter the interior ot' the housing. The insulating panel 18, in this'instancc, is supported by brackets 52, whose lower ends are connected with bracket-s 53 similar to the supporting members 10. The 4.housin ,f 50v is adapted to be supported in a manner similar to the disclosure in Figure 2, i. e., by having a canopy or housing 54 secured on the upper portion thereof by screws 55 or the like, the canopy 54 being provided with an internally threaded boss 56, as in the Amodiiication illustrated in Figure -2 to attach the device to a suitable supporting member, notv shown.
F rom the foregoing description taken in connection with the Vaccompanying drawings, rit will. be readily apparent to those skilled in the art to which an invention of this character appertains that I provide an 'f improved lighting fixture adapted for use with multiple lighting systems which incorporates an individual contactor switch, and which because of a lack 'of necessitv for excessive insulation may have its body formed entirely of metal to lend itself particularly well for ornamental use.
