ANDREW S. HALLIDIE, OF SAN FRANCISCO, CALIFORNIA.
WIRE ROPE OR CABLE.
SPECIFICATION forming part of Letters Patent No. 339,646, dated April 13, 1886.
Application filed November 30, 1883. Serial No. 113,237. (No model.)
5. '0 all whom it may concern:
Be it known that I, ANDREW S. HALLIDIE, of the city and county of San Francisco, and State of California, have invented an Im provement in \Vire Ropes or Cables; and I hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to wire ropes or cables composed of strands, which strands are thenr selves composed of wires.
The object of the invention is to diminish or avoid altogether the wear upon the wires, due to their frictional contact with sheaves or other supports, or to the internal frictional contact of the strands with each other.
My invention consists, first, of a wire rope or cable composed of strands, each strand formed of wires and covered with strips of flat metal wound about the completed strand.
My invention consists, further, of a rope or cable composed of strands formed of wires, having a fibrous filling between the wires, so as to form a complete and smooth cylindrical strand, said strand being covered with strips of flat metal wound thereon.
My invention consists, further, in interposing a thread or wire between the coils of the flat'metallic strips wound upon the strands, to prevent chafing of the edges.
In the accompanying drawings, which illustrate my invention, Figure l is a side view of a single strand, showing the fiat metal strip partly wound thereon. Fig. 2 is a cross-section on line a; of Fig. 1. Fl". 3 shows aside view of the strand partly covered with the fiat strip, and showing also the filling material. Fig. 4 is a crosssection on line a: a; of Fig. 3. Fig. 5 is a view similar to Fig. 1, er.- cepting that the wire interposed between the strips is shown. Fig. (Sis a cross-section of Fi 5 on line :0 a thereof. Figs. 7 and 8 are side and cross section views showing the mode of fastening the end of the coveringstrip. Fig. 9 shows a cross-section of the finished rope.
In the drawings,aa represent the individual wires of which the strand is formed, which may be twisted, if desired, about a core, 6, Fig. 1, of fibrous material adapted to fill the spaces or crevices. The spiral spaces or crevices on the surface of the strand between the individual wires are filled with fibrous material c, Fig. 3, which filling brings the strand to a comparatively smooth cylindrical exterior. These fillings also prevent the individual Wires from frictional contact and chafing with or upon each other, whereas in use without this filling the wires are reduced in strength, and they become liable to break. The outer covering, 6, is a metallic flat strip laid spirally around the strand, as shown, either single or in multiple. The sections of this strip are brazed togelher, and the ends are secured by passing them through the strand and clinching, as shown in Figs. 7 and 8 at h. When the strands thus made are formed into a rope. as shown in Fi 9, the smooth exteriors of these covering-strips,bearing upon each other, diminish the friction caused by the movement of the strands upon each other under flexnre and protect the individual wires on the exterior of the strands wholly from the wear which they would otherwise incur during such move ment, and they protect not only the interior surface of the strands in contact with each other, but also the exterior surfaces, which are the outer surfaces of the rope, and in contact with the supports on which the cable rest-s. The inner fibrous material protects the inner surfaces, or surfaces within the strands, from the effects of the lesser movements of these surfaces. A. fibrous thread or wire, (I, is, when used, interposed between the edges of the folds of the fiat strips, and protects the edges from frictional contact.
I am aware that it is not new to cover a wire rope with a wire covering, and I do not claim this covering of afinishcd rope. A covering thus applied to a finished rope protects the outer surfaces, and to that extent performs the same function as the strand-covering in my rope; but by applying the fiat coveringstrip to the strands I protect the en tire body of the individual wires, not only from the internal wear, or wear of wires by frictional contact with themselves, but I also protect them from the external wear. I do not, however,
limit myself to the use of the flat coveringstrip only in connection with the fibrous filling, as I may use it without that filling and without the fibrous thread or wire d.
I claim as my invcntion- 1. As a new article of manufacture, a wire rope composed of a series of strands made up of individual wires, each of said strands being covered with flat strips wound around the same, whereby each strand presents a smooth surface circular in cross-section, and all abrasion of the strands is avoided, substantially as described.
2. As a new article of manufacture, a wire rope composed of a series of strands made up of individual wires having a fibrous filling between the same, each of said strands being covered with fiat strips wound around the wires composing the same, whereby each strand presents a smooth surface circular in crosssection, and all abrasion of the strandsfii avoided, substantially as described.
3. In combination with the strands of a rope made of individual wires and having a covering of flat strips wound thereon, a thread or wire, d, interposed between the edges of thefolds of said strips, substantially as described.
In witness whereof I have hereunto set my hand.
