No. 820,21 1. Specification of Letters Patent. Patented May 8, 1906.
Application filed July 21, 1903. Serial No. 166,488-
To all whom it may concern.-
Be it known that I, HUBERT KrlANTz, a citizen of the United States of America, residing in the borough of Brooklyn, county of Kings, State of New York, have invented an Electrical Connection for Switchboards, of which the following is a specification.
This invention has for its object to simplify andreduce the number of parts necessary to make electrical connections between the bus-bars, fuse-blocks, &c., of electrical switch or panel boards and the current-carrying posts of such boards. This I accomplish by substituting for the blade riveted to the bus-bar and usually clamped between two washers and nuts on the threaded post an electrical connection comprising a blade having a right-angled extenslon at one end, said extension fitting tightly the post of said board.
In the accompanying drawings, Figure 1 is a view, artlyin section, showing my invention.. 'g. 2 is an end View of Fig. 1. Fig. 3
. is a perspective View of the integral nut and blade; and Fig. 4 is a view, partly'in section, of a IIlOCllfiOitlJ'lOIl.
According to my invention, as shown in Figs. 1, 2, and 3, I form inte al with the blade B a projecting boss e, T 's boss is internally threaded, forming a nut, as shown in Figs. land 3, and is screwed inplace on the post P, the extending blade B being used as a wrench, if desired, until the blade and boss have sufficiently a reached the insulated late I to cause the lads B to lie close to the cure the blade to t bolts 1) b. y i
In Fi 4 I have shown a modification in which t e-boss e is not threaded, but has a tapered opening. The outer end of the post '1? is also ta ered to fit thereon. A screw H may be use to draw the two into close and secure electrical connection with each other. The extendin blade B is similar to that before describe and is secured to the bus-bar .Oby bolts 1) b. If desired, the screw H may be dispensed with and the boss e merely forced-into place on the tapered end of the post.
I claim as my invention- In combination with the insulating-plate of a switchboard and the bus-bar therefor, means for supporting the bus-bar comprising a post projecting from the said late, a bushing forced onto said post, and aving an integral blade abutting against and mechanically and electrically secured to said busbar for supporting the same.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
