To all whom it may concern:

Be it known that I, WILLIAM H. BROWN,

I a citizen of the United States, and a resident of Uleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Methods of Uniting Two Parallel W'ire-Cable Members, of which the following is a full and clear specification.

. This invention hasgfor its ob ect to provide a simple method of permanently clamping or splicing overlapped wire cables, and it will be especially advantageous when I practised in the attaching of the free end of a cable to the main part thereof when said free end is bent back upon itself to form a Y loop or eye, si-nce in this type of splice it view of a comband; and

Fig. 5 is a view similar to Fig. 3 showing a'modified form of die-press and also a modified form of the metal wrapper;

Fig. 6 is a side elevation of my device ap- D plied as a regular splice.

In using my method for making a cableeye, an endless band a: of suitable soft or ductile metal, such as copper or Norway iron, is first threaded upon the cable, then the "bent-over'end of the cable is passed through the band, so that the band encompasses both the free end of the cable and themain part. 'In the cable-loop or eye thus formed, a flanged thimble (not shown) is usually placed so as to be interlocked in the eye when the fastening of the overlapped parts of the cable. is completed.

As'shown in Fig. 2, when the band is put inplace on the overlapped cable members, it fits .the'two members freely, bein materially greater in its'maj or diameter t an the combined diameters of the cables. The

. minor or transverse inner-diameter of the band is approximately the same as each cable, and the end-portions of the band are rounded or semi-cylindrical in order to approximately fit the cables To complete the fastening, the band is compressed inthe di-.

rection of its major diameter, the metal in the band being caused by pressure tofiow sufficiently to bring about a decrease in the major diameter without distorting the general shape of the band, as shown in Figs. '3 and 4:. This compressing of the band .causes the band to become slightly thicker by reason of the re-distributionof the metal throughout the mass of the band. This compression is suflicientto tightly compress the parts of the cable against each other and to bring the curved ends of the band into other will cause an intimate compacting or crowding of the adjacent strands, while maintaining them separate and substantially of initial diameter and without distorting the strands; and along the surfaces of contact between the cables and the band the metal of the band will be indented by the cable-strands to thereby permanently lnterlock, as shown in the enlarged view, Fig. 5. The compression of the band maybe brought about by a die-press, such as shown in my drawing, which may be operated by power-machinery or by a hand-tool, it being important, of course, that the exterior surface of the band shall be supported at all points during the compressing and flow ing of the metal.

It will be understood that I may use either a seamless band, as shown in Figs. 1 to 4, or a band seamed longitudinally by brazing or welding, as shown in Fig. 5. In Fig. 5, I show one longitudinal edge I) of a seamed band extended inwardly to lie between the cable-sections so that whenthe wrapper or band-is compressed, this strip 6 will be indented by the spirally-extending cablestrands 'and will thus materially assist in combating all strains which tendto pull the cable-sections out of the band, the anchoring of the cable-sections in the band being thereby materially strengthened. In this view, Fig.5, I show the matrix of the dieblocks arranged at an oblique angle to the line of pressure, so that the compressing of the band will not cause the band to stlck in the die-blocks when the blocks are separated. It will be understood, of course, thatthe intermediate strip 6 may be made separatefrom the wrapper-band a and simply laid in place prior to compressing the band 1nstead of, as shown, making it integral with the band.

The nature and scope of the invention having been thus indicated and its preferred embodiment having been specifically de-- them separate and substantially of initial diameter, and also to indent the cable-strands into the inner faces of the band.

2. The method herein described of forming a cable splice consisting in overlapping the parts of the cable to be spliced, inclosing the overlapped parts of the cable in an endless metal loop having a major diameter greater than the combined diameters of the two cable sections and a minor diameter approximately equal to the diameter of the cable-section, then by compression and flow of metal decreasing ,the major diameter sufficiently to crowd the strands of the cable-sections and to indent the strands into the inner'surface of the band.

3. The method herein described of uniting parallel wire-strand cable-sections, consisting in placing-a soft or ductile metal band around the same and then compressing the band to crowd the strands of the cables, while maintaining them separate and substantially of initial diameter, and also cause the strands to indent themselves into the metal of the band.

4. The method herein described of uniting wire-strand cables, consisting in placing around the parallel overlapped cable-sections an endless band ofductile metal having an integral strip lying between the cable-sections,'then compressing the band to cause the strands of the cable to'indent themselves into said intermediate strip and also into the inner face of the band.

6. The method herein described of uniting parallel wire-strand cable-sections consisting in placing a ductile metal band around the same and in compressing the band with a uniform pressure all around to crowd the strands of the cable without distorting or changing to any material extent the initial diameters of the cable-sections, the pressure being suflicient to cause the strands to indent themselves into the metal of the band.

7. The method herein described of uniting two parallel wire-strand cable-sections consisting in placing a ductile metal band around the same and then by compression and flow of metal decreasing the diameter of the band sufficiently to crowd the strands of the cable-sections and to indent the strands into the inner surface of the band, the compression being exerted uniformly at all points by a. closed die.

In testimony whereof I hereunto aflix my signature.
