DISTRIBUTING-BOX.

Specification of Letters Patent.

Patented Oct. 16, 1908.

Application filed Janna-ry '.7, 1903. Serial No, 138.10?.

Beit known that l, HARRY Il. HonNsBY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois', have invented a certain new and useful .improvement in Distributing-Boxes, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in distrihiding-centers. These devices as new constructed consist usually of a box in which is suitably supported a panel-board of insulating material. Contact-bars are mounted upon the panel-hoard and the mains or supply-wires are suitably connected therewith. Also upon said panel-board are a plurality of binding-posts connected to said contact bars or strips in any desirable manner. rlhe conH duits for the various circuit-wires are brought to the box7 and from there the circuit-wires extend unprotected from one another to lthe various binding-posts. lf one ofthe circuit- .wires burns out, the others are also burned.

lt is the object of my invention to protect the wires of the different circuits from one another to prevent the destruction of the wires of several burning out.

Another object is to keep the wires of the various circuits distinct f rom one another, so that a particular circuit mavbe readily located.

A still further object of .my invention is to provide conduits for the several circuits leading to a point in proximity to the place of attachment of the circuit-wires upon the panel in order that said wires may be inserted into and extracted from they conduits with facility.

To these ends` my invention consists of the details of construction, arrangement, and combinations of parts, as hereinafter described, and pointed out in the claims.

lo the arcompan \.'ing drawings the various views are as follows: Figure l is an elevation olI my improved distributing-center. Fig. 2 is a cross-sectional view on the line .r r thereol". Figs and `l are elevations ofthe corre spending faces of the sections forming my improved' panel-board Fig. 5 is a longitudinal sectional view through the panelioard. Fig. o is an Vupper edge view thereof. Fig. '7 is a perspective view of another form of my d istributing-center. Fig. S is a broken sectional view taken through the panel-beard circuits in the event of one` iig. 9 is an 3. Said bars are connected at one end with binding-posts i by fuse-wires 5, and in said board near the biiulii'ig-posts are provlded holes or apertures 5. A plurality ot pairs ot contact-strips 7 lare arranged upon said board transverse to the condnoting-bars 3. Each oi" the contact-strips is in contact with either one or the other oi the coudn/tingH bars, and. the arrangement is such that the contact-strips of ea li pair engage different conducting-bar; Each end of the several contact-strips is connected by fuse with one side of a switch 9. The outer side of each of saidv switches is provided with a binding-post 10. To the binding-posts on one side of each pair of contact-strips are connected the wires il of each branch circuit, and a hole l2, thron h Iwhich the wires 1l. are passed, is provided In said board in proximity to each pair of binding-posts forthe several circuits. A casing 13 is arranged around said board in any desirable manner for inclosingthe saine and the various partsniounted thereon. The back of said board is provided with a number of grooves or channels 14, each of which leads from one of the holes l2 in said hoard to the edge thereof. In the drawings are shown live holes for the circuitwircs arranged upon each side of the conducting-bars. The channels leading to the two upper holes on each run to the top edge o the board and toward the center thereof, and 'the holes leading from the lower two holes on each side run to the lower edge of the board and also toward the center thereof. The channel for the other hole on cach side. of the board leads lo the side of the board corresponding therewith.

A board l5 is secured upon the bach of the board heretofore referred to in any suitable manner. Said hack board has its meeting face ygrooved or channeled to correspond to the front board. T he channels or grooves of the two boards are so formed and of such IOC cross-area that they prov'ide smooth, preferably circular,'passages om the holes in the front board to vthe edges thereof, The conduits for the several branch -circuits each By myconstruction the wires of the varim, ous circuits are thoroughly protected one l tion will not be obstructed or ing-centers at present in use.l

ybe done 1f 1t were ,structed, preferably prevent shown and described. without from theother, and therefore the burningof one circuit will not destroy the others. Also the various'circuits may. be readily located, and'cin addition to this the wires may be in serted or extracted from their respective passages with facility. 1f it be -desired to ut in a wire, it may be pushed -in 'throng proppr hole in the outer board and it will wor its Way to the end of the conduit. Again, if the wire be started in at the outer fend of the condult'it will come out of the cor'- res onding hole in the outer board vin prox-y imity with its point of attachment upon said board.

The passages between the boards are'conwithout projections, so that the end of a wire passing 1n either direcy caught in its passage,-4 and also the connection between said passages and their respective conduits is made .smooth for the same reason. Both of vvthe boards also have their meeting faces provided with corresponding grooves 16, extending entirely across the boards and forming a passage through which the main supplywires -17 pass. ,The binding-posts for the conducting-bars are connected with the main supply-wires by wires 18, which pass through theopening provided therefor.

In the construction illustrated in Figs..7 8, 9, 10, and 1 1 in lieu of forming the passages to thel holes by grooves in boards a series o f pipes 1 9`is provided, which communicate with the holes. Said ipes extend straight down from the edge o the board, and the holes with which they communicatevare disposed accordingly. A board 20, bolted -to thefront board, clam s said pipes .in position. Said heir outer ends extended through and are provided with collars 21 to ipes, and the pipes have t the cas' 'splacement of the Vconduits 22 are connected wit threaded sleeves 24.

Thel construction which I: have rovided may beset in the same space as they istribut-v This could not attempted to extend the circuit-conduits directly' to the point of .at-` tachment for the wires, as considerable s ace would be required in order to properly a just the conduits in position.

said pipes by l am aware that variousichanges may be made'. in the details lof construction herein parting from the spirit of my "invention, and

' readily passed through said passay I therefore reserve the right to' make such modifications as fairly fall therein.
