WILLIAM A. DADE AND RICHARD E. MORGAN, OF ORLANDO, FLORIDA.

' INSULATOR.

Application filed January 5, 1917.

To all whom it may concern:

Be it known that we, lVILLIAM A. DADE and RICHARD E. MORGAN, citizens of the United States, residing at Orlando, in the county of Orange and State of Florida, have invented new and useful Improyements in Insulators, of which the following is a specification.

This invention relates to improvements in supporting insulators for electric current carrying wires.

In carrying out the present invention, it is our purpose to provide a supporting insulator for electric current carrying wires whereby the use of tie wires and the like will be avoided, and wherein the body of the insulator will be formed with a downwardly inclined grooveadapted to receive the current carrying wire, and equipped with a pivoted finger arranged across the groove to prevent accidental disconnection of the wire from the insulator.

With the above and other objects in view, the invention consists in the construction, combination, and arrangement of parts hereinafter set forth and falling within the scope of the claims.

In the accompanying draw1ngs:

Figure 1 is a view in elevation of an insulator constructed in accordance with the present invention.

Fig. 2 is a similar view taken at rlght angles to'Fig. 1.

Fig. 3 is a vert1cal sectional view through the insulator.

Fig. i is a horizontal sectional view there through.

Fig. 5 is a detail view showing a modified form of the invention.

Fig. 6 is a perspective view of one of the clips.

Referring now to the drawings in detail,

1 designates the body of the insulator. In accordance with my invention, the body 1 is formed with a downwardly inclined slot or groove 2 that opens onto one side of the body and formed in the top wall of the slot or groove 2 is a channel 3 arranged at rlght angles to the groove. 4.- deslgnates a finger arranged within the channel 3, and havlng the upper end pivoted upon a pm 5 extend ing across the channel 3 at the upper extremity of the latter and having the opposite ends thereof secured 1n alining openings Specification of Letters Patent.

formed in the side walls of the channel. The lower end of the finger f is adapted to move across the slot or groove 2 and engage a channel 6 formed in the bottom wall of the slot or groove 2.

In practice, the current carrying wire is forced down into the groove 2, and in the downward movement of the current carry-- ing wire, the finger .4. is engaged with such wire and swung into the channel 3 so that the current carrying wire may engage the lower end of the slot 2. IV hen the current carrying wire engages the lower end of the slot 2 the finger is relieved of the influence of such wire and drops back to its original position, thereby closing the slot 2 so as to prevent the current carrying wire accidentally jumping out of such slot.

If desired, a second slot or groove may be cut into the body 1 of the insulator at right angles to the slot or groove 2 and the lower end of this second slot terminates above the lower end of the slot 2. This last mentioned construction of insulator is shown in Fig. 5 of the drawings and will be found especially useful in supporting intersecting current carrying conductors.

In order to prevent slipping or creeping of the current carrying wire in the channel 2, we employ wire gripping members or clips at and these clips are placed on the wire and slipped into the channel with the wire and are located in the ends of the channel, as clearly illustrated in Fig. 1 of the drawings. Each clip is formed. of a length of wire bent into substantially U-form, as shown in Fig. 6 of the drawings. The legs of this U-shaped clip are bent at right angles and the confronting edges thereof at the outer end are formed to provide a groove 6 and such edges, inwardly of the groove, are serrated as at 7. The serrated portions of the legs are bowed inwardly, as at 8, forming gripping jaws which firmly grip the wire when slipped into the channel 2, while the grooves 6 embrace the wire and act to hold the clips on the wire when being applied to the insulator.

lVhile we have herein shown and described the preferred form of our invention by way of illustration, we wish it to be understood that we do not limit or confine ourselves to the precise details of construction herein shown and described, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.

e claim 1. A supporting'insulator comprising a body having an inclined wire holding slot therein open at its upper end, a wire retaining finger movable across said slot, and a two-armed wire gripping clip insertable in said slot and embodying opposed inwardly deflected and serrated portions forming wire gripping jaws, and also having convergent end portions to engage the walls of the slot whereby said jaws are caused to grip the wire.

2. The combination with an insulator having a wire receiving channel, of a clip adapted to surround that portion of the wire within the channel and formed of a single length of wire bent upon itself in substantially U-shape and having the legs bent at right angles and the confrontin edges of the legs, at the outer ends, form with grooves and with inwardly bowed serrated portions inwardly of the grooves.

In testimony whereof we aflix our signatures.

W. A. DADE. RICHARD E. MORGAN.
