Specification of Letters Patent.

Application n'ii'aa mm 9, 1901- serial" No. 387,813.

To all it may concern: Be it known that I, LYMAN,G.;REED a citizen of the United States, residing at 'ew Orleans, in the 'parish of- Orleans and State of Louisiana, have invented certain new and I'do hereby declare the'follo win to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which-it appcrtains to make and use the same.

My invention. relates to improvements in panel'board construction, wherein a special arrangement of themain bus bars and branch bus-bars in connection with the usual switches and fuses is provided.

The object of my invention is to provide suitable supports for elevating the two outer bus-bars beyond the plane of the middle bus bar, and to thereby enable the said outer bars to be brought closertogether, panel board made narrower, than has heretofore been possible, and for an object more fully disclosed hereinafter.

A further object of my invention, is to produce an improved form of combined fuseclip and busbar connection, whereby the construction of the panel board is greatly simplified.

.1 Referring to the accompanying drawings forminga part of this specification :Fig-

I ure .1 is a plan view of'iny prnel-board, ar-

ranged forthe ordinary system of bus-barring commonly employed in wiring systems, "an F 1g. 2 is'an end View thereof. Fig.- 3

clued-- to which may be made of any suitable material, but slate is preferred, and b, c and d,the bus-bars of an ordinary three wire system,

5 supports is such that the'neces'sary insulating distance from the middle bar 0 is secured, while their outer edges represent the minimum distance that can be used underthe established rules of the Underwriters Bureau. The 'said middle bus-bar 0 is mounted in the same position as is common in panel boards in general use, but by raisin the outer bars-"b ar d d,, as' abovef describe into a plane above the plane inwhich the bar 0 is placed, they may. be brought much closer together than heretofore, without sacrificing any insulating space;' and'therefore the whole board can be made -narrower than has been possible in the. old-boardsr This feature of narrowing my board, .constitutes an important feature of myinvention, in that by making the board narrower, I not only reduce the cost, but Iam'enabled to locate standard boards of my'make' between the fianges of beams, and in other outof-the-way places about modern stee'l bu'ijld ings, that it is desirable to use, which are now incapable of use for such purposes. The reason why other boards-cannotbe-so located is found in the'faot that the insula tion requirements of the standard board. now used'compelthe same tofbe zit-"leads a certain number of inches WidQ,-al 1d= the fore, spaces between the flanges ofbe I s, ctc., too narrow for such boar'ds calm' j be used for their accommodation. 'Wit-h' niy' boards, on the other hand, while' comply g fully with all "the under-writers? require- 1nents,fI can make them suificiently'na-rro wv m to locate them in such places, and th' 'eby get them out of sight, and out ofthe w .In the drawingsr e represents the clips, f, the fuses, and g the switches wi insulating handles it, all ofthe' usual-q struction, and all occupying the-same space, but accommodated on 'a narrower basethan heretofore.

supports 6 and j for I and d, as above stated,but it is evident that this is not emp'lo ed. v

In igs. 3, 5, 6, 7, 8 and 9, I have shown a modified and improved support 2 for the bars I) and'd, which has integral therewith the fuse clips p. These supports Z are formed from the T-shaped blank shown in I Fig. 9, as provided with the'wings 0. These blanks are struck out of suitable sheet metal, and perforated with the two holes shown, they are then bent up into the form shown in Figs. 7 and 8, providing. the clips p, and. the supports for the bus-bars b and .d:"
