STEEL FITTINGS FOR LOOPED, STEEL, WIRE ROPE CABLES Filed Oct. 19, 1965 LEE MW TrazA/Eb United States Patent 3,243,859 STEEL FITTENGS FOR LOOPED, STEEL,
WIRE RQPE CABLES Frank Savastano, Wayne, and John Rissiniller, Clifton,
.J., assignors to Bergen Wire Rope Co., Lodi, N.J., a
corporation of New Jersey Filed Oct. 19, 1965, Ser. No. 497,979
1 Claim. (Cl. 24-123) This is a continuation-in-part of application Serial No. 330,785, filed December 16, 1963, assigned to the assignee hereof.
The invention relates to steel fittings which are affixed to steel, wire rope cables such that the fitting maintains the breaking strength of the cable. In particular, the invention relates to those fittings which are formed from a cost of producing the finished cable.
The term breaking strength throughout this specification means the strength with which the steel, wire rope cable resists rupture. Maintaining the breaking strength of the cable means the steel fitting will not slip or break when a force less than that required to rupture the cable is applied to the completed assembly.
It is an important object of the invention to provide a steel fitting formed from a flat piece of stainless or carbon steel stock for a steel, wire rope cable having a loop in the end thereof.
It is a further object of the invention to provide such a steel fitting which will provide strength up to and including the breaking strength of the steel, wire rope cable.
These and other objects,
FIGURE 1 is a perspective view of a piece of flat steel stock from which the fitting is to be formed;
FIGURE 2 is a perspective view of the U-shaped form which has been punch-formed from the flat, steel stock of FIGURE 1; and
FIGURE 3 is a perspective view of a steel fitting formed from the steel stock shown in FIGURES 1 and 2 applied which is closed throughout its length at seam 20.
Cable portions 14 and 15 are parallel and tangent to 3,243,859 Patented Apr. 5, 1966 2 each other in at least a portion of the sleeve. The apexes 22 are in a straight line with the diameters of portions points 224 times the diameter of capiece of flat stock into a other along at least part of sleeve; the portion of the length of the sleeve in intimate contact with the steel, wire rope cable being of the order of 6 /2 times the diameter of the steel, wire rope cable, the diameters of the portions of the steel, wire the point of tangency thereof being in a straight line with two apexes of the hexagonal base of the prism, the tangent common to the portions of the steel, Wire rope cable at their point of tangency being normal to two sides of the hexagonal base of the prism, the distance between the two apexes in line with the diameters through the point of tangency being of the order of at least four times the diameter of the steel, wire rope cable, the distance between the two sides of the hexagonal base normal to the tangent being of the order of at least twice the diameter of the steel, wire rope cable such that the strength of the union between the steel fitting and the steel, wire rope cable exceeds the breaking strength of the cable.
