PANEL-BOARD.

Specification of Letters Patent.

Patented Dec. 25, 1906.

. Application filed January 29, 1906. Serial No. 298.340.

To all whom it may concern.-

Be it known that I, JOSEPH J VVEsLEY, a citizen of the United States, residing at the city of New York, in the borough of Brooklyn and State of New York, have invented certain new and useful Improvements in Panel-Boards, of which the following is a full, clear, and exact description.

My invention relates to panel-boards, and has for its principal object the provision of a panel-board which shall secure all the important and valuable features of the usual panelboard having potential and neutral bus-bars, but which is arranged to occupy a reduced or compact compass, so as to take up a less amount of wall-space.

A further object of the invention is to provide a practical construction of the various metallic parts and fixtures which shall be efficient and easy to manufacture.

With these and other objects in view my invention consists in the construction, combination, location, and arrangement of parts hereinafter set forth and shown, and finally particularly pointed out in the appended claims.

In the drawings, Figure 1 is a top or plan View of a panel-board embodying the principles of my invention. Fig. 2 is a vertical sectional view of the same on the line II II of Fi 1, and Fig. 3 is a section on the line III II of Fi 1.

It will e understood that in handling currents in power-stations and in buildin s it is customary to distribute the current om the main line by means of panel-boards from which the various branch circuits are completed as required. The most essential points about a anel-board are that it should e simple and ee from connections or parts liable to short-circuit the bars and, further, that it should be capable of making good metallic connections with the branch circuits when these are switched into action. In carryin out my present invention I aim to secure t ese features in addition to a very compact disposition of the parts upon their supporting-base.

Referrin to the drawings, in which like parts are esignated by the same referencesign, 1 indicates the supporting-base, of marble or other insulating material, which may be supported upon the usual wooden uprights 2. 3 denotes what I shall term a supplementary support and comprises a plat or tablet of marble or other insulating material supported from the main base 1 and in parallel and spaced relation therefrom by any suitable means, as by bolts 4 and distanceblocks 5. A

The bus-bars are indicated at 6, 7, and 8, respectively, of which 6 and 8 are the potential bars, while 7 is the neutral bar. The usual potentials employed are plus 110, zero, and minus 110 volts. The bus- bars 6, 7, and 8 are each held to the supplemental support 3 by bolts 9 and 10 and the bolts 4, above mentioned. The bolts 9 and 10 also serve an additional urpose as conductors, as will be later descri ed Referring to Fig. 1, it will be seen that a number of metallic cross-strips 11 are included beneath the neutral bus-bar 7, being preferably secured in such relation by the bolts 4, which also pass through these metallic cross-strips. The outer ends of the metallic cross-strips 11' areclamped into con: tact with metallic fixtures 12, which form one part of the switch elements. 13 designates bolts for holdingthe cross-strips 11 against the fixtures 12, said bolts extending into holes in the marble, the lower part of which is counterbored, as shown at 14 in Fig. 2. The purpose of having the bolts in counterbored holes is to preclude any possibility of the fixtures 12 becoming short-circuited on the bus bars 6 and 8 directly beneath them, but on the other side of the supplemental support 3. v

15 and 16 designate additional switch fixtures or elements which are res ectively con nected to the bus-bars (land 8 y the screws 9 and 10 above mentioned, which thereby serve the treble urpose of holding the busbars in place, holding the fixtures 15 and 16 in place, and establishing a metallic connection between the two.

The movable switch elements a e designated at 17 in the drawings and Zzomprise double knife-blade switch-arms journaled upon the terminal bars 18 and 1 9 of the several branch circuits. 20 design tes the usual fuses in each terminal of such cuits.

For the purpose of securing a better contact between the various fixtures 12 and 15 and the switch-arms 17 I form the latter in a special way, as indicated in the fi ures, having a metallic tab or lug 21, whicIi is folded over, so as to make a U-shaped engaging clip in connection with the switch-arm, as clearly shown in Fig. 1. This U-clip is Somewhat springy and serves to embrace the opposed metallic edge of the various fixtures 12, 1 5, and 16. 22 designates the usual insulating-handles, each connected to a pair of the switch-arms 17, whereby any desired circuits 18 19 may be completed by moving the handles 22 so that the switch-arms are engaged with a pair of the fixtures 12 15 or 12 16, as the case may be.

It will be seen that this construction provides a very compact panel-board arrangement and one in which all the parts are efficiently protected against short-circuiting and which are capable of makin good metallic connections with the various ranch circuits. Each switch-handle 22 completes one of the branch circuits by connecting its two terminals with one of the potential bars and the neutral bar, res ectively, the upper row of branch circuits eing applied, for example, to the positive and neutral bar, while the lower row of branch circuitsis connected to the negative and neutral bus-bars.

What I claim is 1. A panel-board comprising a main base or support, a su plemental support held in spaced relation t erefrom, potential and neutral bus-bars on opipjpsite sides of said sup- Elemental suplport, tures connected to said us-bars, an switch-arms for completing various branch circuits withsaid fixtures.

2. In a panel-board, a supplemental suport having a pair of potentlal bus-bars on 1ts lower side and a neutral bar on the front or face thereof, and connections by which said bars are placed in closed circuit relation with any desired branch circuits.

3. In a panel-board, a supplemental sup i port having a pair of potential bars on its 1 lower face and a neutral bar on its upper face, fixtures on the upper face of said support, and bolts for holding said fixtures and said potential bars in place and establishing I electric contact between them.

4. In a panel-board, a supplemental support having potential bars on its lower face, metallic fixtures upon the upper face and connected to said potential bars, and switcharms having U-shaped clips or tabs arranged to make contact with said fixtures.

5. In a panel-board, a main base or support, a supplemental support,-bus-bars on the lower face thereof, a bus-bar on the upper face, fixtures connected to said firstnained bars, and additional fixtures electrically connected to said bar on the upper face.

6. In a panel-board, a supplemental support having potential bars on its lower face, a neutral bar on its upper face, cross-strips connected to said neutral bar, and fixtures upon said front face, said fixtures being in pairs respectively bolted to said potential bars and to said cross-strips.

7. In a panel-board, a main base or support, a supplemental support having potential bars on its lower face, metallic fixtures upon the upper face and connected to said otential bars, and switch-arms for complet- 1n various branch circuits with said fixtures.

n witness whereof I subscribe my signature in the presence of two witnesses.
