" 'Y iiiipiicaiion sieri Augusta, isa?. sriripz'aiiavvf" liypreseiitfinvcntioii relates to iiiiproveg ments in lamp socketsof quick detachable ,type Vwherein fan incandescent lamp or electric bulb may with i'ia'cility` and convent ience be applied tolor detachedptro'm the Sismi,

socket. In carrying out'i'hy .invention I utiliz'e a holder within the sockety which is debetween the holder j and f stein, and gripping arms ot resilient metal are employed for receiving'and retainingthe stem. Thile the socketfan'd holder arewspecially designed forV use Vwith vlamps 'of this type, it will be understood that such as wall .plugs toi-electrical connec` tions, may also be used with the lamp Y, socket.
t thus far I tion of the principles of my invention..
t 'to The invention consists in certain `novel combinations and arrangements ot parts aswill hereinafter be more i'ully set forth' and claimed. ln vthe accompanying drawingsv l have illustrated one completev Vexamplel of the physical embodiment of my invention wherein the 'parts are combined and arranged accordingto the bestfmodel have devised for the practical applica- Figure l'is a sectionalview of the lamp socket showing avportion of alamp or elec-l tric lamp bulb applied thereto@ 2 and an annular bead 3 at thel end of the' stem.v The steml and bead of the lampV are designed to co-act with the holder located,
within the socket which latter is fashioned as usual with the shell 4:,open skirt portionv 5 and insulated lining 6. The removable cap 7 of the socket carries 8, and the insulated base block 9 is provided with a pair of terminal bolts or screws 10 and 11 passing therethrough. The lead wires 12 and 13 of the lamp circuit pass through the hollow cap-plug 8 and are lsecured to these terminal posts as usual, `and lto receive' andretain l'the stem .oi4
A transversely f other devices, Y

its' 'Cam-*'18, theiaiter ,located 'Within vthe hollow" base block, are-utilized for controlling t'heflamp, and it 'willf beA apparent that the key, 4when turned at right angles to' thev ypositions' shown in VFi/gureslaiid, will contactgwitli the electrodes fili iaind l5 and move them to the "dottedline positionssof V Figure l. When thev keyis turnedf to Voli position, the cam isreleased from the refsili-. i

'E he lamp they return toV normal end the stein ofthe bulbis linserted as shown in Figure 1'. i
t holderis retained'-within the I lower open'end of the socket, vthrough which he holder ,is tas'hionedoi' resilient metal,
Vand as best seen` in Figure 3 is provided with f .a base ringl)V that-snugly titsv within Vthe lower open end of the socket. The base ring is fashioned with a pair of integral at-l taching arms cally. opposite 2O and Qlfloca'tedat diametri-l Y t pointsoi-the ring and` eachl f arm is providedwith a perforated attach-x ing lugfQQ through which attaching screws block in the socket for the purpose of retainv 9,0 p are passed for securing thearms to the base ing theholder within the open end of the socket asin Figures land 2.
' Atatwo points diametrica-lly opposite the holder is fashioned withV clamp arms as 23 and .24v that kproject upwardly into the socket, andthese arms Aformed with an .arcuateV exterior' Y 100,' groove,which grooves Vare adapted to `clamp vagainst andfsupport thebead `of the lain-p attaching arms, the a i pair lof are-each bead that provides an arcuate linterior.
when it is desired to hold the Alamp in 'd e-l tached position within the socket. f f At their free ends both of the cla-nip arms v f i are'rornied kwith compressible hooks 26, and
these hooks are fashioned with inner'ifaces 27 thatl flare outwardly asindicated in the drawings. Thus as the lamp is I inserted within theopen end 'of the socket and its iio .l holder, the clamp arnis Q3 and 24 whichnor'- f lmally taper inwardly, arespread outwardly y by roinrthe bead Landi of the lamp, until the hooks at the ends of the clamp arms arel -frictionally engaged 'by the bead.l The hooks arethuefeempressed between the bead and the socket shell andirby their frictional engagementwith thebe'ad the hooks hold the stem imposition.
' to the inclined faces' 27 of the hooks and `the resiliency of; the metal of the hooks` the latter tend to Vpull "the stem VWithin the socket thus holdthe Contact point of the 16 oi the socket. The plug may be substi-y tuted for the lamp and used as a `connector in vthe electrical? Wiring;y oa circuit.

- Having thus fuilfliy' described my invention, what I claim as new and desire to secure by Letters Patent is--Y l ofa liolder Comprising a'base ring Within the socket, attaching arms on said-base ring and means for securing the armsto a portionl ofthe socket, clamp arms ofresilient `metal carried" by the base ring, said yarmsV tapering inwardly," and compressible hookV members atV the free ends of'saidl arms. y 2. A lamp holder Comprising e base ring ping as indicd'by md lines, to om the blades or electrodes 33, 38, intdthe Wan,
