To all whom 'if may concern Be it lrnown that l, (leonor: ld, Tiroriris, a citizen ot the Unite@ tates oit ilonerica, 'residing1 at llridgeporh in the county ot Fair-- lield and State ot Connecticut, have inveifited certain new ai'iduseiul Alneproveinents in lianip Receptacles? oil? which the tollowiingl is a specification.

My invention relates to lamp receptacles and particularly to cleat receptacles7 the object ot my invention being` toproride an iinproved receptacle oit this type having,` the advantages set :forth in the following; specitication or shown in the accom pa'njvingr drawings, in which ldig. 1 is a side elevation of a cleat recep taele in which iny invention is embodied in one tering i 2 is a broken plan thereof;

3 is a vertical section on the line SMB, lling. 2;

llig. l is an inverted plan ot the upper portion of the receptacle;

llig. 5 is a plan oif the lower portion ot the receptacle alone;

lig. 6 is a perspective ot a holding ring;

lling. 7 is a perspective ot the lamp supporting; shell.

ills here illustrated, the present receptacle comprises a porcelain base in two parts 10 and 11, the lower portion being transversely grooved at 12 and 13 and having` binding; screw terminals la and 15 tor establishin,fr` a runningl connection with the wire mains. .lhe terminal straps are angled upward at 'their outer ends and carry clamping; screws 1G and 17 b v which mechanical and electrical connection is inade with the terminal plates 15S and 19 mounted on the inner tace oft the base section 11. 11s here shown, the pl ate 18 has a torlred end Q0 adapted to be engaged hy the clamping; screw 16, the head oit which is accommodated, during` the asseinblj,T ot the parte', in the longitudinal groove 21 in the lower tace ot the base section 11, while the latter is pierced at 22 to permit the insertion ot' a screw driver to tighten the clamping1 screw 16 attertheparts 10 and 11 have been brought into register. The other terminal plate 19 has a hoolr end 23 adapted to be brought into engagement with the clamping;` screw 17 by swinging0 the upper base section 11 on the screw 16 as a pivot atter the latter has been engaged in the crotch ot' the fork 20. A groove 211 in the porcelain base sec- Seral No. 237,991.

tion 11 accommodates the head oilV the screw 17 as this portion oit the base is swung` into position., while the hole perinits the insertion ot a screw driver to tighten. up this screw. llt the inner ends ot the plates 18 and '19 are screw bolts 26 and respectively9 which pierce the base section 11 and take into the tapped inner ends ot the spring contact plungers 28 and 29 which torni the termina-ls to receive the contacts ot an Edi- C" f ewan lanip base. These terminals are seated in recesses termed in the outer tace of the boss 30 projecting; from the outer tace ot the basesection 11.

.ln order to hold the lainp in position, l' provide a shell 31 having` bayonet slots which open to the outer inargin of the shell to permit the insertion ot the usual holding pins on the lamp base. The inner end of the shell is flanged at 33 and seated in an annular depression around the baseer the boss 80. lt is engaged and held in this position by an overlying` ring 34: with oilset legs 35 and 36 which bottoni in recesses 37 and 38 and are engaged by screws 39 and Ll() which pierce the base section 11 and take into holding` nuts 11 and 49; countersunlr in the inner face of the base section 11. le tongue 4:3, offset troni the ring SI1, engages a notch 14 in the llange 38 ot the shell 31 and prevents the latter troni rotating.

rlllhe inner end o'l' the shell 31 is threaded at 15 to receive a ring 416 ley which a shade holder or shade 'flange may be secured be tween the ring and the outer tace oi' the base section 11. Various modifications in detail inay be ina-de which do not depart trein what ll elaine as my invention.

1. A lainp receptacle having; an insulating); base pierced by countersunk holes adapted to receive securing' means, and having; a seat on one tace arranged between said holes, a lamp holding; shell mounted on said seat and having a base flange. in combination with a securingrino` overlying` said flange and having lugs otlset into said counten sunk holes and pierced to receive securing screws together with receptacle contacts mounted on said base and arranged within said shell butinsulated theretroni, substantially as described.

2. t lamp receptacle having; an insulating; base, lamp-engaging; terminals mounted thereon, a lamp-supporting shell surrounding said terminals bui; inaulated theie'flmn and lim"- ing an outwardly @Xencling base flange, a holding` ring said Hang@ to hold the shell in pnst-ion on 'die base, n'iezins insulated, from said terminals and engaging said fing to Secure it lo the base, and means vsgociaited with said ring to prevent i'oation of the shsll with relation thereto..
