Application filed September 16,1902. Serial No. 123.609-

To all whom, it may concern.-

Be it known that I, CARROLL POTTER, a citi- Zen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Means for Securing Electric (Jonductors, of which the following is a specification.

Objects of the invention are to provide means for positively securing electric wires or conductors to place on a switchboard or the like and means which will subserve this purpose without damage to the insulation and conductor and without disfiguring or mutilating the switchboard.

To these and other ends the invention consists in the improvements hereinafter described, and defined in the claim.

' The nature, characteristic features,and scope of the invention willbe more fully understood from the following description, taken in connection with the accompanying drawings, forming a part hereof, wherei n Figure 1 is a sectional view of a portion of a switchboard with my invention applied thereto. Fig. 2 illustrates in perspective one form of the spring-wiring staple, and Fig. 3

is an elevational view of another form of staple or the form assumed by both staples when secured to place in the switchboard or sup port.

Having reference to the drawings by letter, (0 represents a suitable support, base, or body, which may be of slate or other material or substance suitable for use as a switchboard.

t represents sockets, which may be drilled or otherwise formed in the support or switchboard. These sockets are coincident and diverge from each other, or, in other words, are arranged obliquely.

The staple is preferably made of springwire and is curved at its outer or head portion, so as to exert a uniform strain on the periphery of the conductor, and thus avoid liability of shearing through the insulation. The staple is represented at 0 in the drawings, and it may have its arms or prongs parallel, as shown at 0 in Fig. 2, or they may be bent obliquely, as at 0 in Fig. 3.

From the foregoing description it will be apparent that when the arms or prongs c or 0 of the staple are driven into the prepared sockets b it will be impossible for the staple to become detached, either accidentally or otherwise, because the tendency of the arms when the staple is subjected to a pulling strain is to approach each other, while the keystoneshaped portion of slate or other hard substance that separates the sockets b effectually precludes this action on the part of the staple.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details without departing from the spirit and scope of the invention. Hence I do not limit myself to the precise construction and arrangement of parts hereinbefore described, and illustrated in the accompanying drawings; but,

Having described the nature and objects of the invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with the refractory body of a switchboard having diverging sockets drilled therein, of an electric conductor, and a keeper having a part to clamp said conductor and having spring-arms which penetrate said sockets and bind against the walls thereof, substantially as described.

in testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

CARROLL POTTER.
