F. a. RE BERG STREET LIGHT FIXTURE Filed. Nov.24, 1924 Patented Mar. 13, 1928.
UNITED [STATES FRED B. REBEBG, 0F CASPER, WYOMING.
STREETLIGHT. FIXTURE.
Application filed November 24, 1924. Serial No. 752,061.
The present invention relates to light fixtures, and more specifically to an improved bracket suspension for streethood bodies 'lor street lighting.
The primary objectof the invention being in the provision of an improved simple and efficient iixture for use in suspending street-hood bodies from poles or the like whereby the bodies may be readily lowered for the purpose of inspection or repairs.
A further object of the inventionis the provision of a novel support for the lamp or streethood' body, whereby the same will be rigidly held in position against swinging, when elevated to its normal position with respect to the bracketor mast arm.
.A still further object of the invent-ion is toprovide an extremely simple, and yet efiicient bracket suspension for streethoods, which may be manufactured at a very low cost, and brackets which may be readily associated. with the present type of street hoods.
Other objects and advantages of the invention will appear in the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing,
Figure 1 is a perspective view showing the preferred embodiment of the device, and showing in dotted lines the streethood body in a lowered position for permitting of the ready inspection thereof.
Figure 2 is an enlarged central longit-u: dinal section through the. improved fixture; and a Figure 3 is a section on the line 33 of Figure 2 looking in the direction of the arrows.
Referring to the drawing in detail, and
wherein similar characters designate corresponding parts throughout the several views, A designates an improved street light fixture embodying a bracket or mast arm B, C a lamp support for detachable connection with a lamp or streethood body D, and means E for raising and lowering of the lamp D with respect to the elevated bracket B; and F a pole forming a support for the fixture A.
The bracket or mast arm B preferably consists of a metallic pipe 5 provided with a quarter bend, downwardly turned portion 6 atits inner end for attachmentwith a pole plate 7, and having a quarter bend, downwardly turned portion formed at its outer end providing a socket 8 for receiving the lamp support 0 when the stroethood body "bent port-ion 6 of thefarin l3, and is provided with fastening means 13'for clamping the inner end of the arm securely in the arcuate way 12 with the flange 9 abutting against the lower face of the plate for preventing arcuat-e movement of the portion 6 within the way 12, due to the downward pull of the outer end of the mast arm. Brace wires 14 secured adjacent the outer end of the mast arm B and running to a strain arm 15 secured to the pole F, and a 3 brace wire 16 securedalso adjacent the outer end of the mast arm 13 and running to the pole F at a point above the plate 7, are adapted to further aid in preventing ver tical or horizontal swinging of the outer 1-. I
end of the mast arm.
The lamp support C for attachment with the streethood body D, preferably consist of a short straight length of galvanized or other non-corrosive metal pipe 17 being formed at one end with an inwardly tapered frusto-conical guide head 18, and being provided at its other or lower end with screw threads 19 for threaded engagement within the usual screw threaded cap 20 of the streethood canopy 21. This pipe 17 is of a size to snugly engage the inner wall of the socket 8 when the lamp is elevated to a normal position with the cap 20 in abutting engagement with the flange 10, for rigidly holding the lamp body against swinging movement in any direction. It will also be seen that the objectof so forming the head- 18 of the support permits of its being readily guided into the socket 8 when the lamp is being elevated to a normal position.
The means E for raising and lowering of the lamp D with respect to the mast arm B, consists of a hoisting rope 22 having one end thereof passing through a restricted opening 23 of the support head 18, and being knotted or otherwise formed as at 24 to provide an enlarged end portion incupuhle of being withdrawn through the restricted opening 23. This rope is guided through the tubular must arm I) and directed downwardly by the urcunte portion (3 :it :1 point relatively close to the pole F. The free end of the hoisting rope may he provided with an snituhle snap or ring 25 which may he positioned ore :1 SltlitllJlC cleut. 26 placed on the pol :it :1 position for permitting of the operator to reudily reinore the rin from the cleut and attach the usual trinnners rope (not shown) when desiring to lower the lamp for inspection or repairs.
The usuul line wires "27 inn he. run from the cro1-x :irin 28, positioned adjacent the top of the pole F, to :1 cro.=s arm 29 ot' the lump l) for carrying: current to the lump in the 11:11:11 munner.
lt will he ohserred that h so downwardly curring the open ends of the 111:1:5t 111111 B thnt water and foreign matter will not lie in the 11-111 and prevent tree sliding movement of the hoisting rope when raising or lowering the lamp.
lhanges in detail may be made without departing, from the spirit or scope of my invention; but,
I claim:
1. In :1 supporting fixture for lamps, the combination of :1 support, a tubular must tllm having :1 qunndrnntul shaped downw:1rdl turned portion formed at its inner end and having :1 downwurdly opening Pfltflitt :1 t its outer end. :i lump support slid :ihle upwnrdl into the socket :11; the outer end of the must arm, :1 pole piece rigidly secured to Filltl support, con'iprising :1 divided (-lnlnp lneinher provided with :1 dowim'urdtr opening :ireuute way for receiring the downwurdly turned inner end of the must :irni. nnd :1 hoistin' rope connected ut one end to the hnnp up ort :1nd ulidnhly extending through the tubular must arm for raising :ind lowering of the lump with re- :-peet to the must arm.
2. In. :1 device of the class des ribed. the eonihinution ot' :1 su 'ipun't. :1 tnhulur must urn: hurin; u quundruntu] shaped portion .t'ormed at its inner end and having an unnulur external flange :1t the end ot the portioin 21nd menus for supporting the 111ml arm in :1 horizontal position and against lateral and turning movement. comprising :1 divided clump member provided with :in urcuute way extending from the outer Fltltt ot the ineinher to the bottom side thereof. suid urcunte way to receive the quundruntul shu'ped portion of the must arm with the annular external flange of the arm engaging the hotton1 wall of the clamp member at the d .1wnw:1rdly opening end of the :treuute way.
