ELECTRIC FITTING Filed April 28. 1922 www WIT/VESSES A TTOR/I/EYS Application led April 2B, 1922. Serial No. 557,154.'

v and Improved Electric Fitting, of which the proved form of electric fitting adaptedy for following is a full, clear, and exact description. n

The present invention relates to new and useful improvements in electric fittings, and

it pertains moreparticularly to fittings for electric lamps.

It is one'of the prima present invention to provi' e a new and imuse in connection with electric y l v lamps made 'in imitation of candles.

' lt isa further-object of the Ainvention to 'provide a fitting of this character in which the ordinary, switch key is dispensed with.

Tt isa further object of the invention to construct the fitting so that it 4maybe selfcontained within a shade orthe like in imi- 'tation of a candle, thusrendering the imitation more' complete.

With the above' and other objects in view, reference is hadto the accompanying drawings, in which- Figure 1 is .a longitudinal sectional view of an electric fitting constructed in accordance withthe present invention; l

Fig. 2 is a-view artlyA in elevation and partly in section, ta ren at right angles to Fi 1' Fig3 is a detail sectional view of the interior structure of the fittingg Fig. 4 is a top plan view of that portion of the device shown in Fig. 2;

Fig. 5 is a horizontal sectional view taken on the line 5--5 of Fig. 1, with the outer shell removed;

Fig. 6 is a horizontal sectional view taken on the line 6--6 of Fig. 1, with the outer shell removed.

Referring more particularly to the drawings, the reference character 10 designates an arm or bracket and secured to the outer end thereof is an ornamental fitting 11. This ornamental fitting 11 forms the base of the electric fitting of the present invention, and it serves to sup ort the same in operative position. Rigid y carrled b the fitting 11, 1s a tubular member 12, an said tubular member .carries on its upper end a block 13 of insulating material. This block f ada ted to be secured to objects of the,

- mounted in sai 13 of insulating material is secured in position on the upper end of the tubular member 12 by means of a nut 14', said nut havmg screw-threaded engagement with. the up. r end of the member 12.

ounted upon the upper end of the block 13 is a lamp socket 14, said socket 14 being adapted to receive an incandescent lamp 15 therein in the ordinary manner. The screwthreaded nut 14 hereinbefore mentioned is provided with wings 16 or the like, which project therefrom, and said wings 16 are ortions 17 of the bloc 13 by means of sma l screws, bolts, or the like, 18. i

The reference character 19 designates the electric current conductors and one of said electric current conductors is connected to a screw .20 carried b the block- 13 near the lower end thereof, t e other conductor being connected lby means of a screw 21 tothe block 13 near its upper end. The screw 20 also serves to secure a contact plate 22 to the block 13 while the screw 21 serves to secure a contact plate 23 to the block 13. This contact plate 23 forms a part of the lamp socket 14, as more clearly shown in Fig. 4f, and said lamp socket is placed by this construction into circuit. with the electricity conducton Surrounding the tubular member 12 is a `tubular member 25, and said tubular member 25 is rotatablyfmounted on said tubular member 12. Threaded vonto the lower end lofthe tubulaimember 25 as at 26, is a disk 27 or the like, and said disk 27 servesv as the means by which the tubular member 25 is rotated about the tubular member 12.

The lower end of the block 13 is provided with a cut-out (portion 28, and rotatably cut-out portion 28 is a. block 29 of non-conducting material. This block of non-conducting material is carried by a member 30, which in turn is connected as at 31, by screw threads to the upper end of the tubular member 25 in such a manner that as the tubular member 25 is rotated, the block 29 will be rotated in the cut-out portion 28. Carried by the block 29 are two contact plates 32 and 33, said contact plates being dlametrically disposed with respect to one another. These contact plates are connected by means of a ring 34 carried by the to face of the block 29.

Lea ing from the lower end of the block 13 to the upper end thereof is a conductor 40, and said conductor has its upper end bent atright angles to provide a contact 41 lyin in the bottom of the socket member' 14, t e socket member 14 being cut out as indicated at 42 to receive the member ell. This Contact member 40 is secured to the block 13 in such a manner that as the block 29 is rotated so that its contact 32 engages the contact 22, the contact 33 of the block 29 will engage the lower end of the conductor 40, as at 43.

Secured in the ornamental fitting 11, is a partition 45, and said partition 45 carries a plurality of resilient. members 4G. These resilient members 4 6 areadapted to engage i notches 4T in the bottom tace of the disk '27,

to retain the several parts in either the "on7 or ott position.

Surrounding then entire structure is a tubular member 50 of porcelain or other suitable material in imitation of a candle, and said tubular structure is adapted to rest upon the disk 27 as clearly shown in Fig. l.

The device operates in the following manner:

Then the several parts are in the position shown in Fig. 1, the circuit to the lamp 15 is complete, the current passing from one of the conductors 19 tothe contact plate 22, to the contact plate 32, around the ring to the c ontact plate 33, through the conductor bar 40, member 11, through the lamp, through the socket 14, contact `plate 23, to the other conductor.

`When it is desired to extinguish the light, it is only necessary to rotate the disk 2T when the block 29 will be rotated through the medium of the tube 25, and move the contact plates 33 and 32 out ot contact with the contact plate 22 and the conductor bar 40, respectively, .thus breaking the circuit to the lamp 15.

`With the several parts in either of these positions, the resilient members 46 will engage the notches 47 to retain the parts against accidental displacement, thus giving to the device all of the advantages of a snap switch.

Thile in the present instance but a single form is shown, it is obvious that various modifications and arrangements of parts may be resorted to without departing from the spirit of the invention and thc scope of the appended claims.
