ELECTRICAL DECORATIVE ILLUMINATING DEVICE Filed Nov. 2, 1928 INVENTOR 32 49a BY CE i ATT RNEY Patented Dec, 2, 1930 UNITED STAT S PATENT O E Y JOSEPH BLOCK, on BROOKLYN, NEW YORK, ASSIGNOR To NoMA'ELEcTmccoEroE-A- Tron, on NEW ORK, N. "1., A CORPORATION OF NEW YORK \ELEc'r IeAL DECORATIVE ILLUMINATING nEvIoE Applic ation filed November 2, 1928. Serial 110,316,837.
This invention relates to electrical decorative illuminating devices. r It is directed to the Provision of a highly ornamental unitary illuminating unit of the alliaracter described simulating, a row of canes. 1 One of the objects of the invention is to provide a decorative illuminating unit of the character described withsimple means whereby a similarunit may be connected thereto and supplied by the same electrical source.
Another object of the invention is to provide a unit ofthe character described with neat inexpensive meansffor protecting and covering the wiring.
A further object of this invention; is to' provide a compact and,ruggeddeviceo f the.v character described which shall be inexpen sive to manufacture, and whichshall et be highly ornamentaland practical and e cient to a high degree in use.
Other ob ects ofthis invention'will in part be obvious and in parthereinafter pointed out. p l a s The inventionaccordingly consists in the features of construction, combinations of elements, and arrangement of parts which will beexemplified in the construction hereinafter described, and of which the scopeof application will beindicated in the following claims. 1 1 In the accompanying drawing, in which is shown one of the various possible illustrativeembodiments of this invention,
1 Fig. 1 isa front elevational view of a unit embodying the invention. 1
Fig. 2 is a partial cross-sectional saidunitu v 33 of Fig. 2.. v,
Referring in detail to the drawings, the numerallO designates a unit embodyingthe invention whichis here seen tocomprise a row of candle simulating members 11 mounted on a base 12supported by legs 13.
The base ,12icomprises an elongated board terial formed with a plurality of centrally surface thereof, Each of saidopenings 15 Fig. 3 is a cross-sectional view taken on line made of wood or any othersuitable ma aligned cylindrical openings 15, in the top conductors 35,
extends only partially into said base and provides a bottom wall 16. Said members 11 comprise tubular members 17, made of papier-mach or any other suitable material for simulating candles. Thelower end portions 18 of said members17 are inserted in said openings 15 and abut said bottom walls 16. Said base 12 is further formed withre- ,duced openings 15a substantially concentric with said openings 15, and extending to the bottom surface 12a of said base.
Electric lamp sockets 19 are fixed within the upper end portions 20 of said tubular members. Each of said sockets 19 comprises an insulating body 21 receiving a screw shell 22 and a central contact 23 insulated from said shell. Electric lamps 24, which may be of any ornamental shape to simulate candle flames are attached to said sockets 19.
Means is provided for electrically interconnecting said sockets 19," as for example in series circuit, to a source of electrical energy. To this end, conductors 25 interconnect said sockets 19 in series, as by soldering the ends 26, 27, of each of said conductors to a central contact of one socket and to the shell of an adjacent socket respectively. l Said conductors 25 extend down through the tubular members 17 and openings '15aand lie against the under surface 12a of said base.
280:, connected to the end sockets 19 extending down through the respective tubes 17 and openings 15a. Said conductors 28,28a, likewise lie against the under surface12a oi the base and are joined into a duplex cable 29 adview of jacent one end 30 of said base. Saidcable 29 Y may be connected to an electric plug attachment '33 adaptedto be connected to any suitable electric power supply. 3 Said plug 33 may comprise a blade plug 33a and a screw plug fitting 33?) adapted for attachment. to said blade plug.
Means are provided for connecting the series circuit through said sockets 19 in parallel to other circuits embodied in units similar to said unit 10. v To this end conductors 35, 36 are connected as by soldered joints 35a, 36a respectively to said conductors 28, 28a. Said 36 also lie against the underr The circuit is completed by conductors 28,
surface 12a of said base 12 and are joined into a duplex cable 37 adjacent the end 38 of said base. Said cable 37 may be connected at its outer end to a blade receiving socket fitting 11. It will now be apparent that upon connecting a unit similar to unit 10 to said socket 41 as by attaching a plug 33a thereto, said unit will be connected in parallel across conductors 28, 28a. Thus said units will receive equal voltages from any power source to which the plug 33 may be attached.
The unit 10 is shown as being provided with eight candles? 11 of varying height. ()bviously any suitable number of candles of any desired heights may be mounted on the base, depending on the ornamental effect it is desired to obtain. I
It will be noted that the exposed portions of conductors 35, 36, 25, 28, and 28a'which lie against the undersurface 12a of the base 12 are all in alignment with the central openings 15a.
Suitable protecting cover means is provided for said exposed portions. preferably comprises a plate formed with a longitudinal central channel 46 of substantially semi-circular cross sections enclosing said portions of the conductors lying against said undersurface 12a. The portions 47, 48 of the plate 45 on either side of said channel 46 lie flush against said undersurface 12a and which also secure the supporting legs 13 to said base. Said screws 49 extend through openings 50 in each corner of said plate 45. The supporting legs 13 are made of rubber or any other suitable material, and each' is formed with a narrow slot 49a communicating with an opening 51 for receiving the head 52 of said screw 49, and with a passage 53 for receiving the shank of said screw. Thus the edge of a screw driver may be inserted through said slots 49a to engage the kerfs 54 in said screws for attaching both the legs 13 and plate 45 to said base 12.
The base 12 is formed with semicylindrical cut-out portions 31, 31a inthe undersurface 12a thereof, at the end portions 38, 30 of said board, registering with said channel end portions 46a, 466 respectively. Thus the end portions 46a and cut-out portion 31 form a cylindrical passage at one end 30 of the unit 10 through which the duplex cable 37 extends, and registering portions 46?) and 31a form a cylindrical passage at opposite end 30 for said cable 29. Each of said cylindrical passages is preferably plugged with an insulat ing bushing 32 through which said cables are threaded.
It will be seen that the unit as above described is exceedingly simple, neat and compact in construction, provides for simple connection thereto of another similar unit, and for neatly and suitably covering all Wir- Said means illustrative and not i'n a limiting sense.
