TIE: FOR FASTENING A LINE WIRE TO AN INSULATOR Filed June 21, 1956 2 Sheets-Sheet 2 l4 pom United States Patent TIE FOR FASTENING 'A LINE WIRE TO'AN INSULATOR Robert D. Knight, Shaker Heights, and Thomas Melville, Maple Heights, Ohio, assignors to United States Steel This invention relates to a tie for fastening a line wire to an insulator and more particularly to such a tie including means for reducing the vibration of the suspended line wire or strand. Ties in common use require the use of tools for connecting the line wire to the insulator. For this reason considerable time is required in making the connection and there is no assurance that the connections will be uniform in strength and/or appearance. The cost of installation is high because of the forming necessary in the field.
It is therefore an object of our invention to provide an inexpensive preformed tie.
This and other objects will be more apparent after referring to the following specification and attached drawings, in which:
Figure 1 is a plan view of one element of our tie;
Figure 2 is an elevation showing the tie in the process of being installed on an insulator;
Figure 3 is a view, similar to Figure 2, showing the installed tie;
Figure 4 is a view, similar to Figure 3, showing a slight modification of our device;
Figure 5 is a top plan view of Figure 4;
Figure 6 is a view, similar to Figure 4, showing a slightly different method of installing the tie; and
Figure 7 is a top plan view of Figure 6.
Referring more particularly to Figures 1 to 3 of the drawings reference numeral 2 indicates a helical wire having a central generally circular portion 4 and generally aligned end portions 6 on each side of the central portion. It is preferred that the helices be of the same diameter and pitch throughout the complete length of the wire, but this is not absolutely necessary and in some instances it may be necessary to vary the diameter of the helices in the portion 4 because of the dimensions of groove 8 in the insulator 10. The helices may be entirely omitted in the central portion 4, but better clamping action is obtained when the portion 4 has helices. The central portion 4 normally extends through an arc of less than 360 as shown in Figure 1 and an arc of 330 is generally satisfactory. The inside diameter of the helices is less than the outside diameter of line wire 12 for a purpose which will appear later. The tie also includes a cam lock fastener 14 which is essentially a spiraled piece of wire having two aligned points P and P spaced apart a maximum distance and a second pair of aligned points L and L spaced apart a minimum distance. The shape of the curves from point P to point L and from point P. to point L may vary, but a hyperbolic or logarithmic spiral is preferred.
The tie is assembled as follows:
The central portion 4 of the helical wire 2 is passed around the insulator 10 in the groove 8 with the end portions 6 being spiraled around the line wire 12 as shown. The cam lock fastener 14 is then placed in position as shown in Figure 2, points P and P receiving the helical wire 2 at junctions 16 between the portions 4 and 6. The fastener 14 is then rotated in a clockwise direc- 2,911,695 Patented Nov. 10, 1959 ICC tion through an angle of substantially to the position shown in Figure 3 where the points L and L will engage the helical wire 2 at junctions 16. Since the distance between points L and L is substantially less than the distance between points P and P junctions 16 are drawn toward each other, thus clamping the circular portion 4 around the insulator. Since the inside diameter of the helices is less than the outside diameter of the line wire 12 the line wire 12 will be securely gripped. The portions 6 also act to dampen any vibrations in wire 12. The ends of the wire making up cam fastener 14 may be turned at substantially right angles to the rest of the fastener as shown at 18 in order to facilitate handling and manipulation of the fastener. The parts 2 and 14 are preferably made of steel but may be made of other suitable materials.
In the embodiments of our invention shown in Figures 4 to 7 the construction of the parts is the same as in Figures 1 to 3 and the parts are given the same reference numerals as in Figures 1 to 3 except for cam lock fastener 14. The construction of fastener 14' is the same as that of fastener 14 except that the ends 18 are in the form of an eye instead of being bent at right angles. However, fastener 14 may be used instead of fastener 14. In Figures 4 and 5 the fastener 14 is located entirely between the line wire 12 and insulator 10 and in Figures 6 and 7 the fastener 14 is located entirely outside of the line wire. In Figure 5 a space 20 is provided between the line wire 12 and cam lock fastener 14. In Figure 7 a similar space 22 is provided between the line wire 12 and cam lock fastener 14'. The reason for the spaces 20 and 22 is to prevent rubbing of the wire 2 and fastener 14 against the line wire 12 when the wind causes vibration of the line wire.
While several embodiments of our invention have been shown and described it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
