ROPE.
Application led September 25, 1923. Serialvlo'. 137,871.
This invention relates to ropes of the kind generally referred to as turn cables, bull ropes or' transmission ro es and has for its main object and feature t e provision ofy means whereby the ldiameter of such ropes may be decreased while at the same time the tensile strength and the wearing qualities of said rope may be increased.
In the accompanying drawing the invention is shown in two concrete and preferred forms in which:
Fig. 1 is a view in elevation, with successive layers removed, of one of the strands of which the rope is composed showing one form of the invention.
Fig. 2 is a cross-sectional view of the strand substantially on the plane of line 2--2 of Fig. 1.
Fig. 3 is a view in 'elevation of a rope embodying one form of the invention, with one of the strands stripped.
Fig. 4 is a transverse sectional view through the rope, substantially on the plane of line 4 4 of Fig. 3.
Fig. 5 is a view in elevation, with successive layers removed of a strand embodying a modified form of the invention.
Referring particularly to Figs. 1 and 2, numeral 10 indicates a fibrous core, 11 is an intermediate layer of helically wound fiatrolled wire, and 12 is an outer covering of fibrous material. The component 'parts of the core may vary but are prefer ly laid parallel tothe axis of the strand. In Fig. 1 the core consists of twisted yarns 13v and in Fig.` 5 of so-called slivers .14. The intermediate layer Vof flatfrolled 'wire is laid helically around the core and is, as will be noted, devoid of an sharp corners. The outer covering is of brous material preferably laid helically.
It will be seen from Vthe foregoin that the intermediate layer of iiat-rolled wire increases the tensile strength of the strand so that I am enabled to reduceits diameter and at the same time obtain the same or greater tensile strength than heretofore; also the wearing qualities of the rope are increased because there are no sharp corners or thin round wires to abrade or bruise the fibrous material.
The stra-nds thus produced may be formed into a 'rope in any of the conventional ways. For instance, as shown in Figs. 3 and 4, a plurality of such strands maybe twisted together, either regular lay or Lang lay. In the present instance three such strands are twisted to ether. As a result of the construction the diameter of the rope can likewise be diminished without sacrificing strength or wearingqualities.
I claim:
1. A strand including. a brous core, an intermediate layer of tensile strength helically wound fiat-rolled wire, and an outer covering` of fibrous material.
2. A strand including: a fibrous core, an a intermediate layerof tensile strength helically wound fiat-rolled wire, and an outer covering of helically laid fibrous material.
3. A strand including: a fibrous core the component parts of which are laid parallel to the axis of the strand, an intermediate layer of tensile strength helically wound fiat-rolled wire, and an outer covering of brous material. i
4. A strand including: a fibrous core the component parts -of which are laid parallel to the axis of the strand, an intermediate layer of' tensile strength helically wound tint-rolled wire, and an outer covering of helically laid fibrous material.
5. A rope including: a plurality of strands twisted together, each strand consisting of a fibrous core, an intermediate layer of tensile strength helically wound flat-rolled wire, and `an outer covering of fibrous material..
6. A rope including: a plurality of strands twisted together, each strand oonsisting of a brous core, an intermediate layer of tensile strength helically wound Hat-rolled wire, and an outer covering of helically laid fibrous material.
7. A rope including: a plurality of strands twisted together, each strand consisting of a brious core the component parte of which are laid parallel to the axis of the m v meats@ stm-nd, an, intermediate la er of tensile strength helically Wound fiat-rolled wire, strength helically Wound Azit-rolled Wire, and an outer covering of helically laid 10 and an outer coverin of fibrous material. iibrous material.
8. A rope inclu ing: a plurality of Signed at Brooklyn, in the county of strands twisted together, each strand con- Kings, and State of New York, this 16th sisting of a {ibi-ous core the component parts day of Sept., 1926. of which are laid parallel to the axis of the strand, en intermediate layer of tensile THOMAS GORE.
