Application November 29,1935, Serial No, 52,251

Figures 22, 23, and 25 are perspective views and Figure 24a section substantially upon the line 24-24 of Figure 23, these figures being of a wire line and illustrating another method of producing the novel wire line end, the completed end being shown in Figure 25.

I In the drawings, wherein for the purpose of illustration is shown both the preferred and modified forms of the invention and wherein similar reference characters designate correspon din g partsthroughout the several views, the wire line is designated in each form as A, and the novel line wire ends are designated generally 13, C D, and E.

, The wire line A comprises a plurality of bend- I able and flexible wire strands shown, by way of "example, as numbering seven and numbered to 36 inclusive, preferably twisted or woven into a line having a rounded cross section as shown, for

, example, in Figures 3, 11,18, and 24. But, with- K p out invention, -a conventional wire line may be "employed having the individual strands of a cross "section other than circular or made up of a plurality of smaller-wire strands, such wire lines 'beingwell known in the art. Preferably, the line is so laid that one strand, 30 for example, is sub-' 25 'stantiallydiametrically opposite another strand,

'33 for example, at any certain portion of the lays,

g as is shown in'Figures 3 to 6, 11, 12, and 18. When a strand is cut back from the free end 3'! of the wire line A and removed, a spiral groove remains, and when two or more adjacent strands are cut back from the wire line end 31, a spiral groove remainseach groove being definedby a I portion of the surface of adjacent strands.

I The wire line ends'B, C, D,and E have features in common and substantially similar corresponding parts or portions, so'that similar reference characters will designate these parts throughout "the views.

' Each ,wire line end B, C, D, and E comprises an eye portion 40, preferably much longer than wide. In fact, so that the wire line can be readily threaded as set out, the greatest width of the eye portion 40 is no greater than the diameter of the line A. Conversely, the diameter of the line A is at least as great as the greatest width of the eye portion 40. The eye portion 40 is preferably 7 oval when viewed through the eye 4| and has its outer extremity of nose 42 rounded by the provision of a bight 43 at this end of the eye portions This nose may be provided with a ferrule or cap 44. Extendingfromthis bight 43 are arms 45 which define a part of the eye 41. The opposite end of the eye portion 40, where it, or the arms45,

join the wire line A preferably is encircled by a coat 46 of metal which extends, as well, over the faces of the free ends of any wire strands 3|] to 36 which may terminate there, thus providing a cap for such free ends. It is preferred that this coat 46 have no rough nor sharp portions.

Now as for the method for constructing the wire line end B, shown in Figures 1 to 8b inclusive. A number of the strands of the wire line A are cut back from the free end 31 to the points 5|! so that there is one or more strand remaining extending beyond the points 50 on the line A. For example, the strands 3B and 35 may be severed at the points 58 leaving, in the example shown, strands 3| to 34 and 35. Thereupon, a number of the remaining strands are out back to the points 5| which are intermediate the end 3'3 and the points 58 of the line A. In the example shown, strands 3|, 34, and 38 are so severed, leaving strands 32 and 33. It will be: noted in Figure 3 that the points where these strands 32 and 33 lay in the line A are diametrically opposite the points 59. The length of the strands 32 and 33, measured from the points 5| should be such that, when the strands 32 and 33 are untwisted or straightened out and then each bent or doubled upon itself to form the bight 43, arms and eye 4|, the free ends of the strands 32 and 33 may be inserted into the spiral groove left in the line A by the removed portions of the strands 3i) and 35, so that the free ends of the strands 32 and 33 will abut the points 56, as shown particularly in Figure 5. The free ends of the strands 32 and 33 may be united to the points of the strands 30 and 35 in any approved way, such as by a weld 52 which is preferably smoothed down. V

The cap or ferrule 44 as well as the coat 46 may be provided also by welding, and the rough weld, as shown in Figure 8a, smoothed down, as shown in Figure 8b.

Referring now to the method of providing the wire line end C, shown in "Figures 9 to 15, a section of a single wire strand, for example the strand 35, is cut back from. the free end 31 of the wire line A to the 'point 59, leaving strands 3|! to 34 and 36 untouched. Thereupon, all but one strand is cut back to the points 5| which are intermediate the end 3land the point 50. Preferably, all but strand 32 are so cut back so that the strand which lies diametrically opposite the point 59 will be strand 32. The lengthof the strand 32, measured from the point 5| should be such that when it is doubled back, as described in the construction of the line end B, its free end may be laid into the spiral groove left by the removal of the severed portion of strand 35, with its free end in abutment with the point 50 and secured as heretofore set out. Preferably, the same welds are made in the formation of the line end C as in the construction of the line end B.

In the form of the line end D,.shown in Figures 16 to 21, a somewhat different procedure is followed to provide substantially the same wire end heretofore described. In this case four strands such as 3|], 32, 33, and 35, are cut back from the free end 31 of the line A to the point 50, leaving strands 3|, 34, and 36 untouched. It will be noted in Figure 18 that the several points 50 are at diametrically opposite sides of the line A. Now, by laying, in the two spiral grooves provided by the removal of these portions of strands 30, 32, 33, and 35,'the free ends of the arms 10 of a pair of hairpin-like wire members, each member having a bight 1| joining the arms 10, so that the free ends of the arms 10 are in abutment with the points 50, and then securing the free ends to the line A, an eye portion is provided which may be additionally treated, as by welding, to provide the cap or ferrule 44 and coat 46. Without invention, but two opposite strands may be cut back as stated and a single hairpin-like member substituted for the pair of similar members described.

In the final method of constructing the novel line end, the procedure is illustrated :in Figures 22 to 25. Here, preferably three strands, such as strands 32, 35, and 36 are severed at the points 50 spaced inwardly from the free end 31 of the line A, leaving the projecting adjacent strands 30 and 3| and strands 34 and 33.1 Two of the points 50 are, as heretofore, preferably on diametrically opposite sides of the wire line A and the third point is at the axis of the line, as shown in Figure 24. Now, the projecting portions of the strands 3t and 3| and 33 and 34 are uhtwisted and their extremities, which constitute the free end 31 of the wire line A, are paired, curved and united in pairs so that a bight portion is formed by the united pairs. Preferably, thev free ends of the strands 3|], 3|, 33, and 34 areifunited by welding so that the cap or ferrule 4| is also formed by the weld. Additionally, the coat #6 is applied, as by welding, more particularly asiheretofore set out. It is apparent that the steps of cutting back to the points 50 and then cutting back to the point or points 5| may be reversed without affecting the method, and that the several welds, if welding is employed, may be made in rotation different from that set out herein, without departin from the spirit of the invention.

The tapered forward end or nose of the wire line end enables it to be readily inserted into a confined space, such as that between a sheave and a block, under derrick sills, or through the rough surface of holes in highway guard posts. Because, in no case is the greatest width of the eye portion of this novel wire line end greater than thediameter of the line itself, any space which will accommodate the line will also accommodate the eye portion, yet a strong, sturdy construction is provided.

It should be understood that this wire line end is provided not to take any exceptionally heavy load but so that it may be linked, for example, to a chain, or may be easily wired to another line in order to cause the line of which it forms a part to follow over the sheave in taking off or putting on a casing line or hoisting cable. In other words, the novel line end is provided more particularly for threading purposes.

The coat 46 has a dual function. Not only does it secure the strands, forming the eye portion, to the line A at the inner end of the eye 4|, but it also covers the more or less ragged or sharp edges at the extremity of the severed strands, so that they will not injure the workmen, damage the rope or line attached to the line A, nor catch upon the walls of the confined spaces through which the end must pass.

Various changes may be made to the form of invention as well as the steps in the method, herein shown and described, without departing from the spirit of the invention or the scope of the claims.
