Specification ot Letters'Patent.

Patented Nov. 6, 1917.

To all whom it may concern:

ment in Electric-Lamp Sockets, of which Be it known that I, Anvm H. Nmzo, a citizen of the United States of America, and residin at New Britain, in the county of Hart 0rd and State of Connecticut, have 1nvented a certain new and useful Improvethe following is a specification.

My invention relates to electric lamp sockets and particularly to the type of socket known as the candle lamp socket. The special object of my invention is to prov de a device which may be applied to an ord nary lamp socket in order to form therewith an electric fitting of the candle type.

In the accompanying drawlngs, a

Figure 1 is a side elevation artially broken away of a socket to wh c an attachment embodying my invention aplied' 2 p Fi 2 is a vertical section through this attac ent alone; and 0 Fig. 3 is a dropped perspective of the parts of the latter.

Referrin to the drawings, my invention is here il ustrated in connection with a socket of ordinary construction having a casing 10, the cap 11 of which is provided with a boss 12 adapted to be screwed upon a fixture pipe 13 through which wires are led to the socket in well known manner. The latter may be of any suitabletype. I have here shown it of the switch type with pull chain 14 for operating the switch mechanism. The socket as usual comprises an 1nsulating body 15 upon which are mounted the lamp-receiving screw shell 16 and center contact 17, together with insulating linlng 18 surrounding the screw shell and in the present case somewhat shortened so that 1t lies within the open end of the casing instead of extending slightly beyond the latter as is ordinaril the case.

The fitting to w ich my invention particularly applies consists essentially in an extension lamp receptacle and means for su porting and electrically connecting t e screw shell 19 and center contact 20 thereof to the corresponding terminals of the standard socket, together with an insulating casing 21 simulatin a candle and adjacent the outer end of w ich the receptacle is arranged. In the particular construction here shown IV have accomplished this end by and 33, the former mounting the screw shell 19 of the receptacle upon a pair of standards 22 and 23, the an g ed outer ends of which are riveted to the usu al base flanges of the receptacle, while their mner ends are effect at 24 to lie within the outer edge of a similar screw shell 25 to which they are riveted, thus aflording a me- 29 and standard 26 thereto. The upper end of the standard 26 is maintained'in centered position with relation to the screw shell 19 and'lnsulated therefrom by means of a disk' 31 of insulation which is perforated at 32 shank of the standard and the second perforation, viz. 33, receiving the recurved end 34 of the standard, leaving the bridge piece 20 exposed above the disk 31 for engagement by the center contact of the candle lamp 35. The disk 31 is provided at 0 posite points on this mar '11 with In 36 which take into recesses 37 ormed in t e wall of the receptacle 19, thus ositioning the center contact accurately wit relation to the screw shell. The disk and center contact are the rivet which fastens the lower end of the standard 26 since the standards 22 and 23 are of such predetermined length with relation to the standard 26 that in the adjusted position of the latter the disk 31 is held firmly against the opposite bottom flanges of the receptacle 19;

The candle-like casing 21 of the fitting rests, in adjusted osition, against the outer end of the lnsulatmg linin 18 of the socket and forms a continuation t ereof extending outward a suificient distance to incase the receptacle 19. The casin may be of glass or other insulating materia made of candle.

The present invention afiords an inexpensive fitting which may be applied to standard sockets to. transform the latter into paper glazed to simulate a wax perforation receiving the retained by but is preferably chanical and electrical connection between 28 and mechanically securing and. electrically connecting both center contact thereon, a lamp receptacle having a shell contacts, a lam socket havin fie standard socket, and an indefixtures of the candle type. Inasmuch as no I I will readily occur to those skilled in the art without departing from what I claim as my invention.

I claim as I my invention 1. A fitting of the type described, comprising'lamp receptacle contacts, plu contacts, standards spacing said receptac e and plug contacts apart and formin the sole means for electricall and mechanically connecting the same, su stantially as described.-
