'PANEL-BOARD.
specification of Letters Patent.
Patented March 6, 1906 Application filed June 9.1904. Serial No. 211,880.
To all whom it may concern;
Be it known that I, Emvns'r- R. Ln MAN- f QUAIS, a citizen of the United States, and n i resident of the city of New York, borough of Brooklyn, in the county of Kings and State.
of New York, have. invented a new and Improved Panel-Board, of which the following is a full, clear, and exact description.
The object of this invention is to provide an improved sectional panel-board, each section of which may be used inde endently, if desired, and whichsections may e combined in an number, so as to make up a panelboar of any desired size.
A further object of the invention is to improve the devices for holding the fuses, so that the fuses may be securely held with proper electrical contact and yet removable at will without danger of injury to the operator.
A further object of the invention is to construct the panel-board so as to minimize the danger of shocking persons operating or adjusting the board.
I attain these objects by certain novel features of structure and or animation in which my invention resides an which will be fully set forth hereinafter and pointed out in the claims.
Reference is had to the accompen ing drawings, showing as an example one o the practical embodiments of my inventive idea, in which-drawings like characters of reference indicate like parts, and in which- Figure l is. a )la-n view of several sections of a anel-boar o eratively joined Fig. 2 is a etail, section t irough two of the sections of the panel-board, particularly illustrating the manner of arranging the busfbars' mi of connecting bars of one section with the other. Fig. is a side elevationof one joi' t'lie panelboard sections, showing theswitches, fuses, and bus-bars and illustrating the )rotectingribs formed on the panel-board an surrounding said; elements to minimize the danger of shocking persons adusting the board. Fig. 4 is an enlarged detail section of the fuseholder, saidsection extending through the two mcmbers of n pnir of holders longitudinally oi the fuse; and Fig. 5 is un clcvutionnl view of one of the members of :1 pair of i'uscholders, this vicw showing the fuse in crosssection.
Thc body (I of the )lll\(l-l)()ill'(lis constructed of porcelain or other insulating materiul in the usual manner. Each section of the panelboard is provided with switches I), l'uses c, and bus-burs '(l, accommodsting two circuits, the connections for said circuits being made in the usual manner. As shown in the drawings, the panel-board is designed for a three-wire system, the currents passing in along the middle bus-bar and out along the side bus-bars. The switches b have handles 1), essentially U-sheped in form and having their limbs pivoted to the knife bars of the switch. The body oi the panel board is formed with a number of integral or otherwise arranged ribs (1 and (1 of insulating Inaterial, preferably that of which the body of the panel-board is formed. Said ribs (1 and (1 lie on all sides of the bus-burs and between the fuses and switch-bars, each section having four ribs (1 and two ribs (1". The upper edges of the ribs lie above the upper extremities of bars, and fuse-holders, so that the person udjusting the parts of the panehbonrd will be contact with any 0 the conducting )arts. The handles 1) of the switches straddic the middle ribs (1." of each section of the board. It will be observed that a section of the panelcircuits are necessary. Any number of sections may be joined together to form a nmltiplc panel-board in the. manner shown in Figs. 1 and 2. This is effected by providing bridge-pieces c, which of the bus-bars of two adjacent puncl-board sections, and which are fastened to the busbars by screws 0 or equivalent means. These bridge-pieces therefore cii'cct secure mecharn panel-board sections-and enable any number of sections to be combined to iorm a panelboardfof any desired size. The advantage of ent, since it enables persons engaged in handling and installing electric apparatus to keep in stockthc material for forming :1 panelbourd of any size desired, and it avoids the necessity of nmnul'ucturing a. separate punclboard for cuch scpuratc job. "ihc sectional pnnel-bmu-d thus constructed is adapted to he htstcncd in a junction, connection, or cquivalcntbox or inclosurc. as will be under stood by persons skilled in the art, and I would here explain that tho novcl junctionbox forming the subject-mutttor of my copcnding application, Scriul ho. 189,120,1ilcd protected as fully as ossible from accidentnh board may be used by itself when only twoare arranged to lie over the contiguous endsical and electrical connections between the.
this arrangement will, it is thought, be appar-' the conducting parts of said bus-burs,switcl1- .n i new January 15, 1904, is especially adapted for this purpose.
The fuse-holders are two for each fuse, said holders engaging the ends of l the fuse, as shown, and each comprises a forkf, in which the ends of the fuse are placed and held, and contact-springs g, arranged one at the outer side of each fork to bear respectively on the ends of the fuse and not only to makeeffective electrical contact therewith, but also to hold the fuses securely seated in the forks. The forks f and contact-springs g are respectively provided with tail-piecesf and 9'', extending at right angles to the forks and springs andseated, preferably, in cavities a in the body of the panel-board. These tailpieces, in conjunction with screws it, serve to hold the forks and contact-springs in place, and the said, screws pass through the panelboard into en agement with the cross connections i on 51c under side of the board, so that the screws serve the double purpose of securing the fuse-holders in place and of effecting electrical connection between said holders and the cross connections of the panelboard, as Fig. 4 shows. It will be observed that the fuse may be readily inserted in the fuse-holders by placing it between the forks f, the contact-springs q yielding outward to allow this insertion and returning to hold the fuse securely place and to insure proper electrical contact between the ends of the fuse and the holders.
Various chan es in the form, proportions, and minor details of my invention. may be resorted to at will without departin from the spirit and scope thereof, Hence? consider myself entitled to all such variations as may lie within the terms of my claims- Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A sectional panel-board comprisin a plurality of sections, independent busar sections mounted respectively on the panelboard sections and lying contiguous when the sections are assembled, and bridge-pieces extended between and attached to the contiguous ends of the bus-bar sections whereby to effect mechanical connections between the panel-board sections and electrical connections between the bus-bar sections.
2. A sectional panel-board comprising a plurality of sections, independent bus-bar tended between and attached to the contiguous ends of the bus-bar sections whereby to effect mechanical connections between the panel-board sections and electrical connections between the bus-bar sections, the said panel-board sections having insulating-ribs extending transversely of the sections between and at the sides of the bus-bar sections, and the ribs of one section registering with the ribs of the other section or sections to form continuous protecting ribs on the panelboard, and the said bridge-pieces being located between the said protecting-ribs.
A panel-board provided with two oppositely-arranged fuse-holders intended respectively to carry the ends of the fuse, each fuseholder comprising forks in which the ends of the fuse are received, and contact-s rings lying outward from the forks and a apted to engage the ends of the fuse-holders, the forks and springs having tailpieces extending laterally therefrom and lying one over the other, and combined fastening and conducting device engaging said tailpleces and passing into the panel-board. I
4. A sectional panel-board comprising a plurality of sections, independent bus-bar sections mounted respectively on the panelboard sections and lying contiguous when the sections are assembled, bridge-pieces extending between and attached to the contiguous ends of the bus-bar sections whereby to effect mechanical connections between the panelboard sections, and electrical connections between the bus-bar sections, fuse-holders and switchesattached to the panel-boards ateach side of the bus-bars and insulatin -ribs a part of which extend transversely o the panelboard sections between and at the sides of the bus-bar sections, and others of which extend longitudinally of the panel-board sections between and-at the sides of the said fuse-holders and switches.
In testimony whereof I have signed nay name to this specification in the presence "of two subscribing witnesses.
