GEORGE MAY SELBY, OF MILLWALL, LONDON, ENGLAND.
ABRASIVE WIRE Born.
Specification of Letters Patent,
f Patented June 10, v1919.
Application filed'J'une 18, 1918. .Serial No.24 ose'o.
To all whom it may concern:
Be it known that I, GEORGE MAY SELBY, a subject of the King of Great Britain, residing at West Ferry road, Millwall, in the county of London, England, have invented new and useful Improved Abrasive Wire Ropes, of which the following is a specification.
This invention has for its object to provide improved wire rope of the kind for cut ting, 0r weakening, other ropes, and for analogous cutting, tearing, or weakening, operations wherein cutting wires are employed with the ordinary wires of the cable.
According to this invention there is combined, with a strand, or with the strands of the rope, additional wires. twisted, or
' stranded, together in a direction the reverse of the direction of twisting or stranding of the ordinary wires of th strand, or strands; to which they are applied, the said additional wires being of metal hard enough to cut, or tear, or sufiiciently abrade, and coiled around, or incorporated with, the other wires of one, or more than one, of the strands, of the rope in such manner, that the said additional wires, will exert a'cutting, tearing, or weakening, action when the rope with which they are combined is drawn across, or otherwise moved in contact with, the object to be-cut, torn, or weakened.
The accompanying drawing represents in Figure l a strand for a rope in accordance with this invention and Fig. 2 shows a rope in which such a strand is combined.
The improved rope may, for instance, be made by stranding, or twisting, together two additional wires of the aforesaid character, as illustrated at a, b, in the accompanying drawing, and coiling such twisted, or stranded, additional wires (1, 1), around the ordinary wires 0, of a strand for the rope, the said additional wires a, b, projecting somewhat from the general run of the rope with which the strand to which they are applied is incorporated. Fig. 1 represents such a strand and Fig. 2 represents a rope made of several strands one of which is a strand with additional wires applied to it, as shown in Fig. 1, while the other strands are ordinary strands of wires 0, although any number of the strands may be like the strand shown in Fig. 1. It will be noted that the abrasive twists a and b are laid in the strand 0 and the latter so laid in the rope that the portions of the twists a and b exposed on the outer surface of the rope, extendina direction substantially parallel with the axis of the rope.
The additional wires incorporated with the rope in accordance with this invention as aforesaid may be'of any suitable shape to effect the desired cuttingaction.
The two, or more, additional wires a b, which are twisted, or stranded, together, and applied to a strand as in Fig. 1, for the purposes of this invention, are twisted, or stranded, in a direction opposite to that in which the ordinary wires 0 of the strands of the rope and the wires a, b,- are twisted, or stranded together. The wires may be made of. any quality of metal suitable for the purpose, for example, the wires a, b, may be made of hawser quality steel and the wires 3 may be made of what is known as plow steel but I do not limit myself to these particular qualities of metal.
In operation, a rope such as shown 1n F1g. 2, and comprlsing one or more strands in which the abrasive cords are incorporated,
is drawn with a cutting or ab'rading action across the object which it is desired to sever. The present rope is particularly effective for cutting metal chains or cables, and may be used to advantage when submerged for cutting anchor chains or cables and the like for vessels or submerged mines, etc. In such case the opposite ends of the abrasive rope could, for example, be carried by a air of mine sweepers traveling on the sur ace of the water and dragging a submerged length of the rope across an anchor chain or cable to be cut. What I claim is 1. A rope strand comprising a plurality of slivers twisted in one direction, and an abrasive cord incorporated in the surface of the strand and projecting slightly beyond the surface of the latter, said abrasive cord comprising slivers twisted together in a direction opposite to the twist of the strand slivers, and being laid in the strand in accordance with the twist of the latter.
2. In a construction such as specified in claim 1, a plurality of abrasive cords laid in the surface of the strand at spaced intervals.
3. In a rope comprising a plurality of strands, certain of said strands being formed of plain twisted slivers, and certain other of said strands covering a construction such as specified in claim 1. p
4. A rope comprising a plurality of strands, certain of said strands being formed of slivers twisted together and an abrasive.
cord incorporated in the strand and projecting slightly beyond the surface thereof, the lay of said abrasive cord in the strand and the lay of the strand in th rope being such that the portions of the abrasive cord ex- 'posed at the surface of the rope extend in a direction substantially parallel to the axis of the rope.
5. A rope comprising a, plurality of strands twisted together, certain of said strands comprising slivers and an abrasive cord twisted together in One direction, the
slivers of the abrasive cord being twisted in the-opposite direction, and the lay of 15 the abrasive cord in its strand and the lay ofthe strand in the rope beingisuehthat the portions of the abrasive cord exposed at the surfaceof the rope extend in a (lirection substantially parallelto 'the axis-of 20
