United States Patent METHOD AND MEANS FOR LASHIN G CABLE James W. Channell, San Marino, Calif. Application November 4, 1952, Serial No. 318,674 9 Claims. (Cl. 140-93) The present invention relates to a method and means of lashing cable.

At the present time it is ordinary practice to provide what is known as a strand which extends between a number of poles, the poles usually being situated, in modern practice, approximately 150 feet apart. The strand is adapted to support cable of different size, the cable being lashed to the strand, particularly where long stretches are encountered, and this task is tedious and painstaking, requires many operations and linemen, together with extensive apparatus.

The inventor, who has had a long experience in the operation of lashing cable to a strand knows that such an operation is tedious and, at present, is accomplished in many ways, such as by providing loops or rings situated at spaced distances on the strand and through which loops the cable is drawn, followed by the placing of a spinning machine on the strand, which machine spins or wraps the strand and cable approximately every 13 /2 inches. Such loops or rings as may be temporarily supporting the cable must be moved forwardly of the spinning machine, which may be done either by a lineman or by automatic means connected with the spinning machine, and upon the spinning machine reach-ing the next pole in the progress of wrapping, the spinning machine must be removed from the strand, and placed on the opposite side of the pole in order to continue the spinning operation. The spinning machine is usually pulled along by a truck or by a rope in the hands of an operator who walks on the ground, and it is evident that if trees or :other obstruction is encountered, that great difiiculty will result so far as use of the spinning machine is concerned. This, for the reason that the rope which pulls the spinning machine will have to be thrown over the obstruction. Furthermore, the bobbin connected with the spinning machine may strike the obstruction, necessitating removal of the obstruction, methods require many tools and operators, and the use of temporary supports, which must be removed, as well as the use of spinning machines, which are quite heavy and difiicult to handle.

An object of the present invention is to provide a simple and expeditious method and means for stringing cable, and one that requires few operators, wherein obstructions, such as trees, do not interfere with the stringing operation, which is inexpensive to use, and which is superior to methods and mean's'now knownto the inventor.

In the drawings:

- Figure 1 is an elevation showing two poles, between which cable is to be strung, and secured to a cable support strand; 7 A V Figure 2 is a view similar to Figure l, the cable having been moved between the two poles and slightly beyond a second pole, with the means of the invention slackly wrapped around the supporting strand and the cable;

Figure 3 is a view similar to Figure 2, with the slack Thus, the present between the two poles removed from the means for lashing the cable to the strand;

Figure 4 is a fragmentary view of the means for lashing the cable to a strand; and

Figure 5 is a fragmentary enlarged detail of grip means between a pulling line and the cable and secured to the means for lashing the cable to the supporting strand.

Referring now with particularity to the drawings, I have shown in the several figures two poles 1 and 2, which are ordinarily spaced apart approximately feet. At 3 is a strand which extends between the two poles and beyond each pole, as shown in the figures, the said strand being held taut between the two poles and any following poles by means of clamps, such as shown at 4 and 5. These clamps are ordinarily known as 3-bolt clamps. As is well known in the art, cable such as 6, is usually on the reel 8, and as the cable is pulled between poles, the reeI is rotated, the supports for the reel not being shown. What is known as a one-bolt clamp 7 is secured to one side of the pole 2, and a straightening shoe 9 is positioned on the pole 2, and through which the cable 6 is passed. The cable 6, after passing through the straightening shoe 9 is secured to one end of a grip 10 of the type shown in Figure 5. In this figure, it will be noted that the grip is of the wire mesh type, and of a diameter not much greater than that of the cable 6. One end of said grip is secured to a pull line 11.

The means for lashing cable 6 to the strand 3 is shown at 12, and constitutes a coil of Wire 13, wrapped upon a split core 14, see Figure 4. One end of said coil of wire is secured to the :one-bolt clamp 7, while the opposite end is secured to the grip 10 by passing said end through one of the loops shown in Figure 5. The diameter of the split core, and the length of the core determines the number of coils of Wire thereon for any given span between poles.

The cable terminal 15 is also known as the distributing terminal, and may be of the type described in my United States Patents Nos. 2,434,102, granted January 6, 1948, and 2,318,755, granted May 11, 1943, and wherein distributing terminals are described which permit the connection of branch cables to the main cable. The exact location of the terminal 15' depends upon the judgement of the lineman, and may be adjacent the pole 1 or to one side thereof, as shown in the figures. Assuming that the strand 3 has been stretched between a number of poles and secured to said poles by the three-bolt clamps, the pulling line 11 may, by suitable means, be actuated to pull the cable 6 through the coil 12 by means of the grip 10, and in so doing, the coils will separate in the manner shown in Figure 2, which is to say, that the coils are loose about both the strand and the cable. When the grip 10 reaches the cable terminal 15, the lineman disconnects the coil end attached to the grip 10 and secures it to a one-bolt clamp 16, which is adjacent both the pole 1 and the cable terminal 15. Each pole, regardless of the number of the poles, has as one side thereof, one of the coils 12, as for instance shown in Figure 1, adjacent the pole 1. Hence, as the pull line moves the cable through the cable terminal 15, the end 17 of each successive coil 12 is attached to the grip 10, and the second coil starts to separate as to convolutions about both the cable and the strand 3, in the manner shown in Figure 2, and so on for all the remaining spans. As the cable is advancing from right to left in the figures, pole 1 is the forward pole of the span which is fully illustrated and is the rear pole of the partly shown. span to the left of the figures. l

After the cable has been moved its required distance between spans of any number, and it is desired to securely lash the cable to the strand 3, the lineman climbs Patented Oct. 23,1956

a pole and either manually, or by apparatus, disconnects the end of the coil secured to the clamp 16, and pulls said coils to tension the same around the cable 6 and strand 3, as shown in Figure 3. This lashes the cable to the strand and does not allow any sag in the cable, whereupon the coil end is again secured to the one-bolt clamp 16, and excess coil wire is removed.

The operation, uses and advantages of the invention just described are as follows:

It is evident from the description as given that a mini mum number of linemen are required for the purpose of stringing cable and lashing the same to a strand; that preliminarily for each pole which is to support the cable, there is provided for the commencement of the span, a coil or wire which is to be wrapped around the cable and the strand, this wrapping being automatic as the cable is fed between poles. It is automatic in its wrapping in the sense that the coils already surround both the strand and a portion of the cable, and continue to surround the cable and strand as the coils of wire are stretched so that the convolutions thereof are further spaced apart. Hence, lashing at all times is effected in the securing of the cable to the strand. The pull line 11 has a length equal to the length of the number of spans for the cable, and this pull line is actuated from one end to draw the cable from the reel 8. After the cable has been strung between two poles, the coil 12 is loosely clamped to the one-bolt clamp 16. When the cable has been completely strung between all poles, the coils are then tightened by the lineman. Thus, the work proceeds rapidly and efficiently and a large number of tools and apparatus are rendered unnecessary in a procedure of this character.

I claim:

1. The method of lashing cable to a supporting strand held between two poles which consists in: passing the strand loosely through a coil of closely wound lashing wire, fastening the strand to both poles in taut condition with the coil between the poles, anchoring one end of the coil adjacent the rear pole of the two poles, passing one end of the cable through the coil, fastening the cable end to the opposite end of the coil, and simultaneously pulling the forward ends of the cable and the coil toward the forward pole and roughly parallel to the strand whereby the coil progressively expands and forms a helix loosely surrounding both the taut strand and the cable supported thereby.

2. The method of lashing cable to a supporting strand held between two poles which consists in: passing said strand through a closely wound cylindrical coil of wire, fastening the strand to the two poles with the coil supported on the strand between the poles, anchoring one end of the coil to the supporting strand adjacent one pole, passing a length of cable through the coil, attaching a draw line to the opposite end of the wire coil and to said cable, and pulling the draw line to cause progressive encirclement of the cable and the supporting strand with turns of wire from said coil,

3. The method of lashing cable to a supporting strand held between two poles which consists in: passing the supporting strand through a closely wound coil of wire, fastening the strand to the two poles with the coil supported on the strand between the poles, anchoring one end of the coil to the supporting strand, adjacent a pole, passing cable through the coil, and anchoring the cable to the opposite end of the coil, pulling the cable to progressively loosely wire encircle the cable and supporting strand as the cable is pulled through the coil until the cable and the encircling wire is adjacent the second pole, then anchoring the loosely encircling wire to the supporting strand.

4. Means for lashing pole-supported cable including:

a supporting strand positioned between a series of poles, a closely wound coil of lashing wire carried on said supporting strand in each span between consecutive poles, means for anchoring one end of each coil of wire adjacent a pole, means for moving a cable end consecutively through said coils of wire and for continuously advancing the opposite end of each coil of wire from one pole to the next forward pole, whereby movement of said last means separates the convolutions of the latching coils, one coil after another, so that the wire of each coil extends heiicaliy substantially the full span around both the supporting strand and said cable, and means for anchoring the forward end of each expanded coil adjacent the forward pole of its span, whereby the cable is carried by the supporting strand in each span by a lashing independent of the lashing between the other spans.

5. The steps in the method of stringing on a series of poles a supporting strand and a cable lashed thereto, which consists in passing a supporting strand thru a series of lashing coils equal in number to the number of spans, anchoring the strand in taut condition to the poles with a coil between each two consecutive poles, anchoring the rear end of each lashing coil proximate the rear pole of its span, inserting the end of a cable in sequence thru the several coils, in each span advancing the end of the cable simultaneously with the free forward end of the coil from proximate the rear pole of the span toward the forward end of the span, thus expanding the coil longitudinally to extend substantially the length of its span whereby the coil decreases in diameter and the separated convoiutions of the coil loosely surround both.

the cable and the strand, anchoring the forward end of the coil proximate the forward pole of the span, pulling the cablev thru the coil thus anchored at both ends into the next forward span, and continuing the process.

6. The method of claim 5 with the further steps of releasing the forward ends of the coils when the cable has passed thru the expanded coils, tensioning the coils to bind the cable tightly to the supporting strand, and finally re-anchoring the forward end of each coil in such tensioned position.

7. In combination a series of poles, a supporting strand anchored in substantially taut condition to each of the poles, a cable extending parallel and proximate the strand, and an individual coil of lashing wire for each span between consecutive poles helically surrounding the cable and the strand, each of said coils being anchored at its two ends proximate the two poles of the span.

8. The combination of claim 7 in which each coil is anchored at one end to the strand proximate the forward pole of its span and is anchored at its other end proximate the rearward pole of the span, the forward anchoring of each coilv being a readily releasable connection, whereby when the cable has been loosely lashed to the strand for the series of poles, each forward anchoring may be loosened, the individual coils may be tightened to bind the cable to the strand for the entire length of the coil, and the forward anchorings again be tightened.

9. The combination of claim 7 in which the forward end of the coil is secured to the strand proximate the forward pole of the span anda terminal is positioned between the forward pole and the point of securing the coil to the strand.
