vFig; 7' is a horizontal section'takenalong 1 Fig. 8 is an elevation of the socket" shell and fthe upper insulaton taken fromthe right hand of the socket shell in.- Fig. 1,
In the'illustrate'd' embodiment, the support 1 for the socket proper comprisesjtwo forked members eachof which has =vertical shanks spaced by an adequate distancefor affording s't' finess to the support and for permitting wires to extend between the inner shanks to.
the terminals of the socket. The lower forlted' i member has as its bottom a suitable threaded I portion, such as an upwardly drawn tubular part 1 for attaching ittothe threaded upper end2 of afixtu rebracket 3,-and has each of novel socket. construction is particularly its parallel shanksprovided with lateral flanges '5 so tlg ateach'shank has a channel shapedtransversesection. "These flanges 5 parallelshank s of the iupper forked p er, and the latter shanks have their outwardly directed faces spaced byla distance f 10i shanks 4: of the lower 'lforked q The upper ma ameies a hints-a1 a top 8 provided with acentral perforation 9 o f '-larger diameterithan that of therivet 10 I which forms .the laxial' contact of the ilamp' socket,

To prevent an undue tightening of the screw '21" from bending the fork shanks to.- ward each other, I place a spacer tube 2i other pair of opposed notches 18 through betweenthe shanks 6 of the upper forked which the terminals let and .15 respectively extend.
The metal socket shellylti seats on a middle 1 insulator 17 (Fig. which has a pair of notches '30 clearing thesa'id ternnnals, and
this insulator in-turn seats on the support top 8. A third'or'upper insulator 18 seats on the bottom of the socket shell, both of the 15 insulators 17 and 18 being shaped as shown in Fig.- 5.- The wire terminal 15 extends to the top of the upper insulator 1S and then fiatwise along the said top, and the rivet-1O passes through it, so that this single rivet O secures the socket shell to the upper supporting member and holds the interposed insulators in effective position, while the upper head of the rivet contac" minal 19 of the lamp bulb 20. The companion terminal 14 extends into the bore of the socket shell and is secured to the latter so as to afford theother circuit connection to "the socket. i
' To keep the socket shell spaced from the vire terminal 15 and the rivet 10, I provide the bottom of this shell with a notch 31 as shown in Fig. 7, which notch connects with an opening 34 in the lower part of the side of the shell as shown in Fig. 8. TheirI preferably alsoprovideithe upper insulator-'18 with a pair of projections 32 disposed at opposite sides of the notch 33 through which the terminal 15 extends downwardly, and indent the socket shell adj acentto these pro-' jections so that the lateral edges of the notch 33 engage the said projections. This engage ment prevents the'upper insulator 18 from rotating in the socket she'll, so as to inter: lock these parts rigidly evenif the other wire terminal 14' (which is secured to the socket shell) should be narrower in width than the notch 13 through which it extends. h
To look the slidably interfitting forks of the two forked members to each other I enrmeans the shanks 4 of the lower forked mem ber) and which extends through vertical slots 22 in the shanks 7 ot the companion forked member, this screw being threaded 'into one of the shanks a as shown in Fig.
When the screw 21 slightly loosened. the
with the axial 'ter-..
ploy a single screw 21 which spansitheforkof the member in which the shanks a-re'more Widely spaced (which in the illustrated case "member and extend the screw through it,
" from the top of the socket shell to the bottom of thesupporting member; thereby enabling the installing electrician to adjust the length accurately and quickly without using thus guarding against having the supporta rule alongside my candle socket. Moreoven I preferably provide each shank 7 o f-the upper forkedmember with an outwardly directed finger 26 for supporting an insulating tube 27 which fits loosely between the socket shell and the usual candle-simulating tube 28 which houses my entire candle socket.
Bymaking the notches in the lower insulator of widths corresponding respectively to those of the two wire terminals and of the upper fork-shanks 7, I prevent a relative rotation of these parts. And, since; the terminal 14 is fastened to the socket shell 16, I likewise prevent the shell from rotating on the supporting member, while the previously described arrangement prevents the upper in- .sulator 1S and the two wire terminals (14 and 15) from rotating about the axis of the socket shell. Hence the single rivet l0 suffices for-holding-the entire upper part of my I candle socket rigidly assembled. Moreover,
since the insulators and the two forked mem-- bers are easily formed by simple punch press operations, my entire appliance can be cli'eaply manufactured.
I-Iow-ever, while I have illustrated and dc scribed my invention in an embodiment including numerous highly desirable details of construction and arrangement, I do not wish to be limited to these, since many changes might obviouslv be made without departing either from the spirit of my inexample, it will be obvious that "the" term support as used in the claims refers to the upper portion of the upper forked member of the illustrated socket, and that my invention- .wouldoperate equally well if other means were employed for supporting this support. v
