ROPE.

APPUCAHON FILED JUNE l3. I919.

ROPE.

Specification of Letters Patent.

Patented Feb. 24, 1920.

Application filed June 13.1919. Serial No. 304,054.

To all whom zt'may concern:

Be it known that I, NATIIAN It. Surinnoun, a citizen of the lfnitcd States, and residing at l-lighhmd Park, in the county ot Wayne Lind State of Michigan, have inrcntrd a new and improved Rope, of which the following is a specification.

The object oi the present invention is to provide a composite fiber and wire rope of greater strength for a given size and wei ht than has been obtainable heretofore, an it consists in a rope formed from a plurality of strands of twisted hemp, sisal or other strong fiber said strands being simultaneously tightly twisted together with one or more small wires of steel or other' ductile metal having hi h tensile strength.

In the drawings, Figure l is a side view of a short section of the finished rope, the ends being unraveled. Fig. 2 is a diagrammat-ic side view showing the several strands and wires that make up a single cord. Fig. 3 is a side view showing the preferred relation of the strands to one another before twisting. Fig. 4 is a similar view after the parts have been twisted. Figs. 5, (3 and 7 are sections on the lines 5-5, 6-6 and 7 of Fig. 4.

It has been proposed to make sewing cord of a plurality of strands each of which is formed of a plurality of fibres around which a wire is twisted--see U. S. patent to Briggs, $6,577. August 3, 1886. In practice, the wire thus placed forms a sheath for the corresponding straiid, rather than a component part thereof, and tends to unwind when tension is applied.

According to the present invention, I take a plurality of strands 1, Fig. 2, of usual rope material (such as hemp or sisal binder twine) each of which comprises a number of fibers twisted together, and twist said strands tightly together with one or more wires 2 of iron or steel or other metalhaving a high tensile strength, whereupon they assume the appearance indicated in 4. This action is to be carefully distinguished from what would occur were the several strands 1 first twisted'together and thereafter wrapped or twisted around with a wire, even though the latter were of the some pitch as the strands. In this latter case, the wire would always be on the outside of the strand, whereas, according to my invention, it is at certain points on the outside, again at the center, anc at still other points is intermediate between the two, as indicated in F1 s. 4, 5, 6 and T. The course of the wire is ike that of any particular fiber. of ordinar binder twine; and the practical result is hot the wire enters with the strands to form a cord or rope wherein both the tensile strength of the fiber and the tensile strength of the metal is eflicieiitly utilized, and in which the fiber acts as a cushion for the wire, thereby preventing breaking under sudden jerks.

The resulting small cord or rope is preferably finally twisted with additional cords or ropes as indicated in Fig. 1 thereby forming a completed rope of a size suflicient to meet the particular need. F or some purposes the single element shown in Fig. 4 will sufiice. The number of strands 1 may, of course, be varied as may the number of wires which go to make up the corresponding cord, but it ispreferr'edto use four strands and two wires for each cord.

I claim 1. A. cord formed of a series of strands of twisted fiber such as hemp c" sisal twisted tightly together and simultaneo'usl with a wire of stron tensile metal twiste in with the strands o fiber so as to lie arallel therewith, whereby theposition of the wire in the cord is at some points on the outer surface of the cord and at other points is inter mediate between the center of the cord and said outer surface.

2. A rope comprising a. plurality of cords tightly twisted together, each cord including a plurality of strands of twisted fiber and one or more small wires of strong tensile metal, twisted] in with the strands of fiber so as to lie parallel therewith, said strands and wire or wires bein simultaneously twisted together, and the wire or Wires being on the outer surface of the corresponding cord at some oints and being near the center thereof at o't or points.
