Specification of Letters Patent.
Application filed September 27, 1911. Serial No. 651,565.
T 0 all "whom t may concern:
Be it known that I, HUBERT F. KRANTZ, a citizen of the United States, residing at Brooklyn, in the count-y of Kings, city and have invented certain new and useful Improvements in Switchboards, of which the following is a clear,
- joints and thus improve the full, and exact description.
The object of this invention is to improve the construction of switch boards and the like, to simplify the connections, reduce efliciency of the board.
Another object is to provide a compact and inexpensive switchboard in which a maximum clearance is provided between conducting portions of unlike polarity.
In carrying out the invention, my switch board is adapted to make immediate contact between the switch plates and the bus bars, which supply current to the board. I am thus enabled to greatly reduce the cost of a switch board as well as to reduce the number of connections necessary for the installing wire man, and so prevent disasters if the work is not properly installed.
In carrying out my invention, I provide an insulating slate back plate and run the bus bars in a plane extending vertically parallel with one face of the same, connecting them with a. source of power in the ordinary way. The various circuits to be supplied are led` to the board by conductors, and not byv struction, particularly when the blade or brush is mounted in line with a bus bar, although in all cases this might not be necessary. Fuses or the like may be carried by the insulating block between the lug and the switch blade or brush.
The scope of my invention will be pointed out in the claims.
vIn the accompanying drawings: Figure 1 is a face elevation. of a portion of 'a switch board, sufficient to illustrate my invention in connection with two switches. Fig. 2 is a section cut by plane N in Fig. 3.
Fig. 3 is a perspective of the arrangement shown by Figs. l and 2 diagrammatically exemplifying the various primary planes of this arrangement and the relation of the various elements thereto. The peculiar relation between the primary elements of this combination, as shown in Fig. l, may be more easily analyzed by reference to Fig. 3 which shows the same structure in perspective. The disposition of these elements will be explained in conjunction with what may be regarded as the three primary planes of the combination. These are indicated by B, I and N; B being a plane common to the positive and negative bus-bars indicated by and respectively, and extending parallel with the base-board l. N is a plane arranged transversely to plane B and containing and defined by the longitudinal axis of the negative bus-bar -3 said bus-bar being elongated and extending adjacent to and parallel with a face of the base-board 1. This plane N also contains theseveral negative switch-blades -S and -S, etc., and also contain certain auxiliary parts. Just as the plane N defines the various negative elements of the switch-board, so also in like manner the adjacent parallel plane P defines the position of the various positive elements. That vis to say, plane P longitudinally intersects the elongated bus-bar and extends parallel with plane N and transversely to the plane B common to the bus-bars of different polarities. The plane P contains the various positive switchblades +S and +S', and also certain other parts as will be described. It is to be noted that the negative switch-blades -S and -S are all arranged 'n alinement in endwise succession; e., tandexnwise, and they swing or move in the plane N and are spaced apart endwise so that their appropriate ends may swing directly into contact with the negative bus-bar. A similar relation obtains with respect to the positive switch-blades and, furthermore, it is to be noted that the positive and negative switch-blades are also disposed so as to, lie in alinement in pairs; z. e., the switches -S and +S form the advance pair and the switches -S and +S forming the following pair; it being noted that the members of each pair or set diler RFllSS U El.)
