BINDING DEVICE FOR PANEL-BOARDS.

' Application filed March a, 1911.

tions and constructions hereinafter set forth and claimed.

In describing this invention reference 18 had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure l is an elevation partly in section, panel board embodying mydnvezition. Fig. 2 is a sectional view of such panel board showing one of the terminals in section and another terminal in elevation.

1 is the base of the panel board which -may be of any desirable form, size and construction.

I and 3 are respectively sets of conductlng bars, the bars of each set being arranged one above the other when the panel board is in horizontal position and supported by suitable pillars -1 which include spacing rings 5 of insulation located between the bars. The sets of

bars

2, 3 extend parallel to each other and the individual conducting bars are connected, respectively, in different circuits as meter circuits. However, one set of barsmay be omitted if desired.

The terminals are arranged about mid way between the bars .3, 3 and are con nected to bars 6 which are in other circuits than the meter circuits and are connected to corresponding sides of the load circuits, the opposite sides of which are connected to bars '7 in circuit with the main conductors of the panel board. he arrangement of the circuits connected to metering panel boards is well known and further description herein is unnecessary as this invention relates in no way to such circuits. However for a full description reference is made to my pending application, Sr. No. 585,598.

Specification of Letters Patent.

these sleeves of-insulation Patented Dec. 1, 1914. Serial No. ($13,209. 4

meter circuits by a connecting member 8 to be described. Each terminal comprises a post including a plurality of spacing rings 8) arranged one above the other around a suitable support 10, any two of the spacing rings being adapted to receive a. connecting member 8 between them; and a sleeve 11 of insulation encircles the spacing rings and support therefor, and is formed with a plurality of transverse slots 12 in one side thereof for exposing the edges of the abutting end faces of contiguous spacing rings 9.

In my application 585,598 referred to, are shown as formed of a plurality of rings, one insulatmg ring for each spacing ring, but the constrliction shown herein is much more simple as 1t requires no fitting together of the various rings composing the insulating sleeve. As illustrated, the sleeve 11 is composed of two sections, the upper section bemg provided with the slots 12 and the lower section resting directly upon the block 13, presently described. Each terminal may be of any desirable form, size and construction and as here shown, it comprises a base block 13 l of the panel board, ametallic internally threaded sleeve 14; mounted above the block 13, a clamping member, as a screw 15, extending through the base 1- of the panel board from the rear-side thereof, through the block 13 and threading into the. lower end of the sleeve H, the support 10 which is a screw threading into the upper end of said sleeve, the screw 10, one above the other, the lowermostnormally resting on the sleeve 14, and a nut 16 turning on the upper end of the screw 10 against the uppermost ring 9. The

movement of the nut 16 outwardly is limited by the head 17 on the screw 10,1such head 17 permitting suflicient movement outwardly of the nut to allow the spacing rings to be separated sufficiently to permit the insertion of but one of the connecting members 8 between adjacent rings, or between the lowermost ring and the sleeve 1%. When the slots 12, in the sleeve 11, face one set of conductor bars, as the bars a connection may be made by a member 8 between a bar of that set and the part of the terminal having electrical conductivity. and at the same time the intact part of the sleeve is presented to the other mounted on the base 'spannenare setdfbarseas the bars. 2', for preventing the w-bility'of a-connection bemg made one of-"the'same' and the termiznal. The terrdi'nals a'rebracedat their .outer ends iby' -or spanners, 20, one

--being preierabgsassociated with two conpanionfapplicati' 'nhereinbefore referred to.

.As-here1. shown, the -opposite ends of a tojthe pillars. 4 and the middle part of the s provided with s'eparated. openings 13 which receive the sleeves 111. rTheupper end-of each sleeveis preferably provided"with a shoulder 18 overhanging the edge of the opening through Whi hjth e sleeveexten'ds. A'set f'screw 21".is preferably provided for prevei' ting the aecidentahturning'ofi the sup- *port 10' in referenceto the sleeve 14.

' The end portion-22 of each of the bars 6 is'oflset from the base 1, overlies and is .usually-sunk into the upper end of the blOeklB is pierced-by .the screw 15, and the sleeve 14 is seated on said port1on'22'1n' electrical contact. therewith.

.The connecting member 8 1s l here shown as of substantiallythe same construct on as that shown and: described in my pending application 585,598 referred to, said member'being formed-of astrip of metal bent upon itseliat-23 'inorder to'form spring jaws" forembracing oneof the bars 2 or one of the "arms as 2d of the strip being "longer than the other and having a bifurcated end 25 adapted to be inserted through one of 'the slots 12' between two of the spacing rings 9 or. between the lowermost spacing. ring 9 and the upper end of the sleeve 14L, as clearly shown in the drawings.
