To all nio/nt it may concern.' Y 1 .Be it known thnt'l, FRAM' "V BURTON. e; citizen of the lUnited States of America, andvl residing :it Bridgeport. in the county. of Fztiilield and State of Connecticut, have,

invent :d a. certain 'new and `iiiipriwed Current-Tappet `which the following is :i specification. 1

My invention relates toA current. taps und lthe object of iny invention is to provi-'ile a* siniple and efficient current tap device which entry he readily applied to various ittings of standard type to afford av detachable conncction 'tor e branch` circuit. V A

ln the accompanying drawings l hdve shown iny invention applied to e standard electric lmnp socket. Y

vert-ical section therethrough 3 is a detached vertical elevation of the seine., partly ii section, showing them-(inf. ner in which the device is installed;

` i 'w @perspective of thc tnp casing; .i o side elevation ot the t-.ip device s :i section on the line Fig. l. En the 'torni here shown niy invention is illustrated in conjunction with a pull socket oi standard tjy'pc comp n capv 10 :ind shell il adapted to he sleevedl together and provided withinthe sleeving aren. vwith latchingv elements oit the type shown in the. Goodridge Petcnt- HKLQSJSQS. i'i the normal installation ot this socket the sl'ieil 1l and ccp l() :ire hitched together and the bushing l2, carried hy the cap, is screwed onto a lixture 40 pipe 13. 'through tholnttery the lending-in wires all and l5 are introduced to the interior of the socket and are connected to vthe Wire terminals l@ sind i7 on the insuinting' body 1.8 of the socket. The circuit is coinpleted through the socket lmnp terminale i9 'sind 2@ hy ineens of o switch mechanism of any suitable-type operated hy the pnil chain 2l. it frequently occurs that n drop light Lor other 'supplemental fitting is desired in addition to the lmnp carried hy the socket.

To )afford convenient ineens from which current may be taken to said snppleincntnl fitting, l provide rthe g'iresent independent tapappliance for the socket.

tapping appliance comprises ecasing terminals 1G and 1T.

22 oit thesanie general charncte' as that of the socket and provided at one end 'with letcliin-g elements 23 adapted to enter the cop and cooperate with the letcliing elements thereon', While et its other end it is provided with latching elements 2i adopted to coperzlgte With the latching elements on the slccvc 1l. `ln other Words the tup casing hns at one end latching elements 2i correspondingtc those on the cup l0, while at the other end its letcning elements 28 correspond to those carried by the shell so that the hip casing teiescopically engages und latches with the cmp and shell in precisely thc sanne manner es the clip and shell normally hitch into engagement with euch other. W'ithin the tup casing 22 is en insulating block 23 having secured thereto, on opposite sides of nv barrier 'web 26, :i pair of terminal plates 2'( and 28, cach carrying two binding screws '29 and 30. This tup block 25 is provided with e 1Doss 3i adapted to project thron-fli :in aperture in the casing 'and pierced by two openings und 3ft in which litl terminzrls 35 and 3G, respectively connected to the plates 27 and 28 and adapted to receive the jacks or" :in atteclnnent plug. The barrier 26 is beveled :it 3T opposite the hose 2li to facilitate the adjustment 0i' the lei. Koel: in its casing :22 (see Fig. 3).

The manner in which the present device is assembled and used is readily unde When it is desired to insert the noi e. socket oit the type descrihmh inc shell l1. is detached from the cap and the wires lei and l5 are freed from the socket Wire The. Wires are then drawn doivn far enough to permit-'them to be itt-ached tothe respective Wire terminals 29 on the tap block. 26 which has previously been removed from its casing 22 Short connecting ivires'SS and 39 are then secured to the respective .binding screws 30 on the iep block, leaving their other ends free. he trip casing 22 is then adjusted over the tapbrlocl l/.y tilting inoven'ient, iliustriited in Fig. 3, and pushed. up into liitciiing en gagenicnt with the cap l0. In this position the tup bloclcis housed by its casing 22, but the ends oi' Wires 3S and 39 project beyond the lower edge thereof a. sufficient distance to permit theni'to loe secured to the socket wire terminals 16 vand 17. respectively. In order to make this connection the socket body 18- is lifted suiiicie'ntly out of the shell rSO tapping off a branch circuit by means of an out interruption to the socket Wire terminals 16 and 17 as before, While at the same time the tapping terminals and 36 are brought into circuit and aird convenient means for v attachment plug. The terminals 35 and 36 are preferablyyof such construction-and arrangement that they will receive the aeks of standard attaehmentplugs. 1

1t is obvious that the present ytap' devicemay be employed with any fitting having a sleeved easing between the parts of which the tap sleeve 22 may be inserted. Thus it.' 'could be used with apendent switch or a il naine.

Wall socket, or any other suitable appliance,i A

and I- do not limit, my invention tothe pre- 7 cise structure shown. Moreover, the' details; of the tap sleeve and 4block may-be variousl modiied as will readilyoceur to those skille claim as Kmyflinvention, l I cla1m asfnyjmyentlon:
