rlhis invention .relates to vapparatus Ausable in .connection with Ielectric'current distribution. The object of the invention is toV provide means which whilst, being adaptable for electric lcurrent distribution in certain spe-y cific cases is also .usablewithcertainelements as a switch' box, Yjunctionfbox, fuse box, cou-n or test, inspection or other box or l pling box, otherwise, the boxitselfand appurtenant parts beingl interchangeable so; that-.fthe ap,- paratus .will be serviceable Vtor providing electric current to circuits asfrequired.

The f yapparatus have associated therewith variable elementswherebyV electric current distribution may be eected.

Referring to the accompanying drawings',l

in .which the-invention is illustrated, Fig'. 1

respectively cross-sectionsonplanes 3-#3 and` is of metal; itshead has a tapped opening 2 andl itsfoot is formed with a flange 3 to seat against theflange t onv the head of the metal base 5. Preferably' the interior face of the coveris furnished with suitable electrical in- `sulat-ing material .6. An yintegral element 7 is adapted tobe carried centrallyfwithin the cover 1 and base 5. Such element7 is prefer-A ably constructedl of metal yand isU-shaped havinglateral foot flanges 8 and/9. `r-it its head. itlisipreferably formed with a boss 10 M comprises a base, a coverV plate,.arndan integral element adapted tois a perspective view ofthe integral element Y from which Vprojects the vertical. tubular member 11 having an externa-l screw-,tlyiread-` 12. Such member 11 projects through the tapped opening 2 of the cover 1 which opens' ing is of larger diameter than the member 11. lThe outer tace of the member 7 isfurf" vnished with electrical insulating fmaterial* 13,"and the bottom of the base 5 is 'suitablyV ormedvtoreceive the holed plate 14e towhich' the element 7 may be attached 'by meansof 'l the angled brackets 15 and rivets -16 as well as screws 17 or otherwise.. It required .the

base 5 may be connected toa base plate 18 f by the screws 19 or other suitable means; thel said base plate 18 will be hereinafter de-V 65 Y scribed. Components 69 of suitable'type'forx electric current distribution'work may be ata.

tached by thescrews 73 or otherwise to` thej element 7. f

ln Figs. 5 to 8, the integral element 7 isf7`0 shown with openings 89 in its opposite side walls, such openingsbeing intended to serve v as bearings Jigor parts of any rotatable switch .gear which may be utilized with the apparatus When such switch gear is used it is also 75 preferred to provide in association with the element 7 the shield 2O one end of which is suitably attached to the head of the; element' 7 and the other endvthereo to the holed plate.`

14. Such plate'lli is shown in Figs. -7 and 8 80 `with an opening 21. The shield 2O mayservev the purpose of protecting the electric'lead .wires Jfrom contact with the switch mechasl nism. It required 4one end ot the element 7 f may be extende'dras at 22 to receive parts, say 23, of switch mechanism to'be used; One

Ytypev vot switch operative means 96 is shown` in Fig. 7, part of such means being fitted l in the openings 89 in the element 7 and turn'- able therein.

A union connection for tlieapparatusris shown in Figs. 3 and .4 and 7 and 8..v Inthe said figuresV the threadedtubular. connection .24 is shown, the said connection being screw-l threadedrexternally to t thetapped open= ing 2 of the cover 1 and also screw-threaded. internally tot 'the tubular member 11 onthe element v7 Upon attaching the connection 241s'k to the tubular element 11 andscrewing same home thereon and also screwing. the cover l 101') onto the lsaid connection the cover 1 is made attachable to the baseyr and the element 7, the

rim anges

3 and 4 onthe cover `1 and base 5 beingthus made to abut one another. The connection 24 may be used when the apparatus is intended for utilization either as for a pendent or for wall bracket attachment.

-Y Further modificationsk of the apparatus are illustrated in Figs. v9 to 11. When openings arerequired in the base 5 to enable the apparatus to be adapted fondi-Herent uses these may1 be provided.. In Figs. 9 and 10 the base 5 s s own with an openingY to receive the pro- 1'5 jecting coupling 32 whose rearend is preferably furnished with a fiange 33 to seat against the base 5. VA cap 34 with serrated edge 35 abutting vthe base 5 Vfits about the coupling 32 and may be secured thereto by the screwsV 36. i VSuch coupling may be internally screwthreaded to recelve anV externally screwthreaded conduit 37, but if the coupling is not internally screw-threaded avconduit may be tached by bolts 55 and nuts 56 to the base 57 and such casing may carry an electrical insulating block 57 having electric conductive tubes 58 for a plug connector 59 having projecting plug connector pins 60. The switch block 93 in Fig. 11 has associated therewith 'the conductive contact plates 96 with which the movable conductive plate 97 may be made to Contact or not, depending as to whether the switch operative meansare set to Von or off posltion.

If the apparatus is desired for junction use "the Velement 7 may have attached thereto (Figs. 2, 3, 4 and 10) either one or both the Y electric insulating blocksV 69 preferably having the rib 70; these blocks may have suitable terminal means 71 and 72 thereon and they` may be secured to the element7 by screws 73. A lsimilar arrangement Yof in-vv sulating blocks 93 are shown inFigs. 8 and` 11 in connection with the element 7. when designed for use with( switch means; onl

one such block (Fig. 11') is usedif the switch7 is to be of the single pole type, but if of the double poleA type (Fig. 8) two such blocks are used. When blocks are -used for switch means of single pole type one of such blocks 93 maybe used as a switch block andthe other block may consist of a junction block 94. The rib 70 of the

blocks

69 and 94 serves to prevent contact between the lead wires to the terminals of such blocks. Only one fuse block 95 may be used if desired. In Fig. 9 the ele# will be earthed and ment 7 is shown associated with a switch block 93 and also with a fuse block 95 of suitable type.

Referring to Fig. 3, the element 7 and base 5 are shown associated with the metal base plate-18, screws 19 being utilized to attach lthe plate 18 to the bottom ofthe basei. i The base plate 18 has a neck 63 whose inner end may abut the bottom of the base Y5l lwhen thehase plate 18 is set on the base 5. The "base late 18 with parts of the apparatus-attached t ereto'may beconnected in any preferred manner to any suitable support.

struction of the various combinationsy of in# v'It will be understood that theprovision ofV the base plate 18 and the connection and confAY S07 tegers above described 'and illustrated in theV 'i drawings with the base 5,'the latter'being f associated with the" cover 1, oterswmeansV whereby if any short-circuitingzof current? :should occur in using the apparatus the latter current may then ow l .n I V to earth.

and a shield member embracing the element to protect the parts.

5. An electric current distributor as claimed in claim l, in Which the said base member is provided With a plurality of openin s a metal cou lino havinO' a flange seat- 7 C C b ing Within the base and about said openings, a metal cap fitting about said coupling and having one of its ends serrated and abutting said base, and means for securing said coupling and cap to each other.
