WIRE CABLE.

SPECIFICATION forming part of Letters Patent No. 403,319, dated May 14, 1889.

Application filed March 6, 1883. Serial No. 266,317. (Specimens.) Patented in England August 25,1888, No. 12,285.

To all whom, it may concern:

Be it known that we, TELFORD CLARENCE avrei-Innen. and ARTHUR LATCH, subjects ot the Queen of Great Britain, residing, respectively, at S Barons Court Road, Vfest Kensington, county of Middlesex, England, and at Biddiek Hall, South Shields, county of Durham, England, have invented new and useful Improvements in lVire (fables, (for which we have obtained Letters Patent in Great Britv ain, No. 12,285, oli August 25, 1SSS,) oi which the following is a specification.

lleretofore wire cables have been composed of strands each comprisingl several wires twisted together, such strands also being,` spirally wound or twisted together to `forni the rope or cable. In the prior constructions the completed cables are composed of strands round or circular in cross-section, and con sequently their outer surfaces present very few individual wires to the surface of wheels or rollers at the point ot' contact, so that the cable runs in a very marked manner upon the particular' individual wire presented to the pulley as a pointoi' support, which causes excessive strain and wear to be placed upon that particular wire, in addition to which the wire bears the crushing' action due to the weight of the cable while passing over a wheel or roller. In some instances a cable made oi? strands, as above set forth, has been enveloped by wires laid thereupon and conforming to the round or circular shape in cross-section, but in case of fracture ot such external wires they would unravel and the rope-be rendered useless.

The object oi our invention is to avoid the above objections, to improve the construction ot' wire cables, and to provide a wire cable built up of a series oli substantially flattened strands each comprising several wires and a core, so that a plurality of wires must at all times bear uniformly on a wheel or roller continuously throughout the length of the cable.

The objects oi' our invention we accomplish by the novel features of construction and arrangement of parts hereinafter described and claimed, reference being made to the accompanying' drawings, in whichliieure l is a transverse sectional view of a wire cable embodyinp` our invention; Eig. 2, a side elevation of a portion of the same; Eig. 2l, a transverse sectional view of a cable, showing a modification; Eig. 4, a side elevation of a part ot one of the strands composing the cable shown in Figs] and 2; Eig. 5, a transverse sectional. view ot the strand shown in Eig. 4:; Eig, o, a transverse sectional view of one of the strands composing" the cable shown in Fig". 23, and Eig. 7 a sectional plan view ot a modilied construction of strand.

In order to enable those skilled in the art to malle and use our invention, we will now describe the same in detail, referring iirst to Figs. l and 2, where it will be seen that the cable is composed et' a central core, l), oi' suitable n'iai'erial, preferably hemp or other :ilexible substance, about which are spirally wound six strands, cach strand being substantially .flatten ed and composed o t' two cores, A l, Figs. -l and 5, about which are spirally wound the extern al wires, C. rlhe cores A ll are each made up of a series ot' wires sph-ally wound together, like an ordinary wire rope, and when two of such cores are laid parallel to each other, Fig. l andthe external wires, C, are laid spiraily thereupon, the strand so produced will be substantially l'lattened, the opposite surfaces each comprising' a plurality of wires. A. series oi these strands-say sixbeing` spirally wound on a core, D, a cable is produced, such as shown in Figs. l. and 2.

In the construction shown. in Eig. 23 each strand, instead oi having; opposite and parallel substantially-tiattened sides, as in Fig. 5, is substantially triangular in cross-section, and comprises three cores, A A B, each core bein made of a series of spirally-woun d wires in the same manner as described with reference to Fig. l. The three cores being laid together, as in Eig. (i, and the external wires, C, wound spirally thereupon, it follows that the completed strand will be provided with three substantially-lattened sides, each conlprisinlbr a plurality of wires.

A cable may be made to embody our invention from strands-such as shown in Eig. 7 where the cores A ll are each composed cfa single Wire, on which the external Wires, C, are spirally Wound, so as to provide opposite and parallel substantially-iiattened sides or surfaces.

By our construction of a cable it is impossible for a single Wire alone or any tWo Wires alone to come solely in bearing-contact with a Wheel lor roller; but, on the contrary, a plurality of wires of each strand Will bear on the Wheel or roller, andconsequentlythis greatly increases the durability of Wire cables.

In a cable made' up of substantially-fiattened strands, as described and shown, a plurality of Wires comes at all times during the traveling movement of the cable 1n contact with the Wheel or roller or other support, so that We avoid running the cable on a particular Wire, which is objectionable, as before stated.

The series of substantially-flattened strands when made into a cable are so arranged that they conjointly conform to the exterior surface of the cable approximating to a circle, and as the external Wires of each strand are spirally Wound around its Wire core said external Wires are carried to the inside of the cable at frequent intervals, so that in the event of fracture of any one or more of the wires the unraveling would only occur for the distance such Wire or Wires are exposed on the outer surface, which part could be cut out Without destroying the usefulness of the cable. f

Vhat We claim isl. A wire cable composed of a series of spirally-Wound substantially-flattened strands, each strand comprising` a core and spiral Wires thereupon, substantially as described.

2. A wire cablecoinposed of a central core and a series of spirally-Wound substantiallyflattened strands thereupon, each strand comprising,r a Wire core and spiral Wires thereupon, substantially as described.

3. A wire cable composed of a central core and a series of spirally-Wound substantiallyflattened strands thereupon, each strand coinprising independent cores A B placedside by side, and spiral Wires C thereupon, substantially as described.

In witness whereof We havehereunto set our hands, in the presence of two subscribing Wituesses, this 1st day of February, 1888.
