METERING PANEL-"BOARD- Specification of Letters Patent.

. 1'0 will whom it may concern.-

Be it known that I, ARTHUR C. MoWIL- LIAMS, a citizen of the United States, residing at Chicago, in the county of Cook and State panel-board by means of which any load-circuit or any number ofload-circuits may be thrown onto any meter by the act of merely connecting a short loose wire or other re movable conductor to two closely-associated contact-points on the board and to render it throughout the several views.

"ppssible that this may be done without the necessity of having the different loose conductors cross each other. I attain this oldject by the apparatus shown in the accompanymg drawings, in which F1 ure 1 is a front view of the board, show ,ing t e permanent Connections thereon and,

also showing one torn orary or removable conductirigwvire, where y a certain load-circuit is thrown onto a certain meter-circuit. Fig. 2 is a sectional view taken on line 2 2, Fig. 1, showing the preferred form of contactpiece or binding-stud.

Similar letters refer to similar parts The parts are mounted upon a board a, which consists of marble, slate, or other suitable insulating material.

In the deslgn here shown the board. is adapted for a three-wire system of electrical distribution, and three main bus-bars Z), c, and d are permanently mounted upon the board. Permanentl connected to the out side bus-bars l2 and are meter-terminals e arranged in pairs, one terminal. 6 of each pair being permanently connected to one of the outside bars I) or d, and the other terminal f of each. air bein ermanentlv connected to one of t e parall e conductor-bars g, which. latter are preferably-mounted on the back o the board and for convenience may be designated by numbcr-platcsg, running in the 1contact-piecc for each bar 9.

present instance from 1 to 6, as shown in Fig. 1. For convenience also it is desirable to place corresponding plates 6 adjacent to the pairs of meter-terminals e In the present three-wire design bus-bar c is neutral and by preference extends along the board in a line coincident with the median line of the apparatus, so as to pass between the double row of load-terminals h *5, arranged on either side thereof. One'terminal h of each pair of the load-terminals is permanently connected, preferably bymeans of a conductor-bar h, to-bus-bar p, and the other terminal i has, a binding-post t, by means of which a removable conductorsuch, for example, a loose'wire-may be detachably attached. For reasons which will hereinafter more fully appear I prefer to so arrange bars h that the load-terminals will occur in groups of four pairs in a group, the terminals 2 being on the outside of the group and the terminals i on the inside thereof, with. the

binding-posts t lying adjacent to each other,-

two on each side of the median line of the aparatus. It is desirable that each pair of cad-terminals be appropriately designated by plates if, which in the present case are letteredzfrom A" to H.

The conductor-bars 9 above mentioned, which for the sake of symmetry should be substantially parallel, extend transversely 'to the rows of load-terminals h t,.so that each bar g will cross in front ofeathliinding-post t. Electrically connected to each bar 9 at a point between two adjacent binding-posts iare secured contact-pieces the preferred construction of which is shown in Fig. 2.. As there illustrated, a stud j is electrically connected to bar g on the back of the board and projects through to the front, where it is secured by a lock-nut A screw cap or nut 7' is provided for removably attaching a loose conductor, such as the wire it shown in Fig. 1.--

Studs of this kind are now in common use and are desirable; but any other suitable form. of contact-piece may be employed which is capable ;of completing the electrical connection between a bar g and a loose or removable conductor or Wire, such as the wire In this arrangement, therefore, the conductor-barsg lie parallel to the median line of the apparatus and parallel to the rows of load-terminals h t, and there is a row of contact-pieces extending transverse to the median line, one

There is a contact-piece (in each bar 9 for each group of IIO four loadterminals, and in the present inpairs of stationary load terminals; a bus-bar stance, in which there are eight pairs of loadterminals, there will be two transverse rows of said contaet-pieces In operation when the electrician desires to throw a given load-circuit onto any predetermined meter all he has to ,do is to supply a short piece of condu ting material, such as loose Wire k, and attach it at one end to a binding-post 'i and at the other end to the proper contact-piece For example, suppose it is desired to throw load-terminals B onto meter-terminals.6, it is only necessary to run a short wire is from the B binding-post t" to the 6 contact piece or stud j, as shown in Fi 1. In this illustration the Worst possible case is shown, for here it is necessary to bridge from the left row of load-terminals to the extreme right end of the row of contactfifieces. If it had been desired to throw load-terminals B onto meter-circuit 1 only a very short piece of wire would have been required. It will be noted-and this is one of the advantageous features of my board-that any one of the group of four load-t-erminalsfor example, A, B, E, F---or'all of them maybe connected to any meterterminal without the necessity of having any one loose wire cross anyoth'er loose Wire, and it will also be noted that the above may be accomplished by means of' only a single transverse row of contact-pieces j for each group of tour load-terminals.

in Fig. 1 there is illustrated a meter and meter-circuit ;\l and load-circuit L, and in order to make the description of the device intelligible it has been necessary .to herein refer to one set of terminals as meterter minals and to-the other set as load-terminals. It'is obvious, however, that there is no reason why the load-circuit could-not be connected onto the terminals which I have termed meter-termiiials" and the meter circuits upon the terminals termed loadterininals. The compactness of construet'ion and the universality or flexibility of the apparatus would in no degree be lessened if the so-called meter-terminals were. Incated'where the hard-terminals now are and the so-called load-termimils" were located where the meter-terminals now are, and I wish itto he understood that in interpreting the annexed clai. is the Words meter" and load" may be transposed without departing from the spirit of my invention.

Although the present board is well adapted for a three-wire system of electrical distribution, it is equally well adapted for a two- Wire system, for it isobvious that the busbars I) and (l could both be at the same potential as well as at'dillerent potentials.
