To all whom z't may concern.'

Be it known that-I, RAYMOND H. OLLEY, of Syracuse, in the county of' Onondaga and State of New York, have invented a new and useful Panel-Board, of which the following is a specification.

My invention relates to panelboards and has for its object a particularly simple and efficient arrangement of conducting bars and terminals thereof, and it consists in thecombinations and constructions hereinafter set forth and claimed.

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

Figure ll is a plan, partly in section, of a panel board embodying one form of my invention. Figs. 2 and 3 are sectional views taken respectively on lines A-AU and B4B, Fig. 1. Fig. l is an isometric view of a portion of the panel board, parts being omitted. Fig. 5 is a vertical sectional view of parts seen in Fig. 4. Fig. 6 is a detail view of the insulating rings ofthe terminal posts.

This panel board comprises, generally, a

-base or panel board proper which is usually a slab of slate or marble, a plurality of conductors supported by the base, one above the other when the panel board is in horizontal position, the conductors being adapted to be connected in dierent circuits, terminals arranged in a series along the conductors on the same side of the base as said conductors and being designed to be connected in other circuits, and means for connecting the terminals to any of the conductors.

This invention is here shown as embodied in a meter panel board, and two sets of conductors are shown arranged parallel to each other and adapted to be connected in circuit with the meters and the terminals arearranged in a row midway between the sets of conductors and are designed to be connected in the load circuits.

1 is the base of the panel board; 2 the main or supply conductors connected to the

bus bars

4 and 5; 6 is the neutral'main conductor connected to the bus bars 7, a switch 8 and fuses 9 being interposed between the mains 2, 3 and 6`and the bus bars 4, and 7. The

bus bars

4 and 5 are connected through fuses 10 and 11 respectively and 3 arev to terminals 12 and 13, and these terminals 12 andv 13 are connected through wiresleiy tion and connected respectively by wires 20 .and 21 to the

meters

16 and 17 on opposite sides of the base 1. Of course, when the panel board is in use it is usually in vertical position and the

bars

18 and 19 are arranged one infront of the other. The term one above the other` when the panel board is in' horizontal position is employed merely tor convenience. The wires 20 and 21 are con nected to the ends of the bars 18 and at 22 and 23 and the end portions of alternating bars of each set are defiected laterally in opposite directions (Figs. 1 and ll) in order to facilitate the connection thereto of the aires 20 and 21. The

meters

16 and 17 are connect ed with wires 24 and- 25 respectively connected to the neutral main bar 7.

26 and 27 are terminals arranged in a series extending along the

bars

18 and 19 and pre erably midway between the

bars

18 and 19. The

terminals

26 and 27 alternate with cach. other and are connected respectively to

bars

28 and 29 connected to terminals 30 and 31 through fuses 32 and 33, each terminal 30 or 31 being connected to one side of a load circuit 34 or 35, the opposite side of which is connected to a terminal 36 or 37 which is connected to a

bar

38 or 39 extending parallel to the

meter bars

18 and 19, the bars 38 aint 39 being connected to the neutral bus .bar 7. Suitable fuses 40 and 11 are also interposed between the terminals 36 and 37 and the

bars

38 and 39.

Any one or all of the terminals 26 and 2l may` be connected to any one of the

meter bars

18 or 19 by interchangeable members which are duplicates so that vit is not neces Patented oet. 24., 1ere.

' of the maj-sr pari but the combined thickness of the parallel portions of the connecting members and Said portion of the handle having the inclined surface is'greater than the distance between two of the meter bars 18 or 19 and thus an imperfect connection between the connecting member and the meter bars is prevented, as when the parallel portions of the connecting member do not straddle the meter bar.

The *arrangement of the meter bars and the terminals for the load circuit bars is -particularly advantageous in thatl any terminal may be connected on the upper side of the base to the meter bars at a plurality of points at intervals lengthwise of the terminal, and the described means for electrically connecting said meter bars and terminals is advantageous in that like connecting members serve to make all of the desired electrical connections between said bars and terminals, and said membersare readily and quickly forced into or, out of operative position by a single sliding movement. v
