DEAD-END-WIRE CONNECTION Application filed September 16', 1926-.

This invention relates to connectors and especially a connector such as is required to anchor the end of an aerial wire.

A principal object of this invention is to produce a dead end connection for a wire line which will be simple to manufacture, in expensive to manufacture, easy and inexpensive to install and efficient in use.

Other objects and advantages will appear as the description of the particular physical embodiment selected to illustrate the invention progresses, and the novel features of the invention will be particularly pointed out in the appended claim.

In describing the invention in detail, and the particular physical embodiment selected to illustrate the invention, reference is had to the accompanying drawing, wherein we have illustrated a particular preferred physical embodiment of the invention, and wherein like characters of reference designate corresponding parts throughout the several views, and in which:

Figure 1, is a side elevational view of our dead end connection, including a support to which it is attached, and the wire held by it; Fig. 2, is a cross sectional view on the plane indicated by the line 11-11 of Fig. 1, viewed in the direction of the arrows at the ends of the line.

In the drawings the numeral 1 indicates a fragment of the well-known crossarm. Through an orifice in the cross arm 1, extends the member 2, which in the form shown is a cylindrical metal member, screw threaded on one end and made integral, on the other end, with anelongated annulus 3. Anut 4;, is threaded onto the end of the member 2, and so serves to hold the member 2 in position in the cross arm. Theusual washers 5 and 6, are interposed, as shown, as is usual, so that the wood of the cross arm is not injured.

The annulus is in form elongated, the body being preferably made of round metal, preferably iron. The end portions of the annulus Serial No. 135,796.

are dissimilar. One end is struck from a center, as 7 whereas the other end is struck from a center, as 8, to two being merged by the line as 9. This construction provides a space about thecenter 7, through which theannulus 10 made of insulating material, may readily pass transversely to theannulus 3. Theannulus 10 is formed with a peripheral groove 11, so that when theannulus 10 is positioned in the space of which 7 is the center, and then pushed toward the other end portion of theannulus 3, the groove 11, co acts with the body of theannulus 3, so that when theannulus 10 is in the position as shown in Fig. 1, it cannot then be moved transversely to theannulus 3. The position of theannulus 10 as shown in Fig. 1, is the position which theannulus 10 would take and remain in when pulling force is applied to thewire 16, which dead ends at theannulus 10, by being looped through theorifice 12 in theannulus 10, and then fastened to itself by any suitable means as by a clamp 13.

Applicants prefer to make theannulus 10 somewhat elongated as shown in side elevational View in Fig. 1, so that better bearing of the body ofannulus 3 in the peripheral groove 11, is obtained.

Although we have particularly described the construction of one physical embodiment of our invention, and explained the operation and principle thereof, nevertheless, we desire to have it understood that the form selected is illustrative, but does not exhaust the possible physical embodiments of the idea of means underlying our invention.

What we claim is new and desire to secure by Letters Patent of the United States is:

A dead end construction for a wire line, comprising an elongated annulus of substantially circular cross-section and having opposite end portions constructed with openings formed upon different radii, the opening of the inner end portion being larger than the opening of the outer portion,asecond annulus 7. end.
