.EDIVARD P. FREDERICK, OF ST. LOUIS, MISSOURI.
CABLE-STRAND.
SPECIFICATION forming part of Letters Patent No. 586,706, dated Ju1y`20, 1897. Application niet Jimmy 9,1897. sani No. 618,577. un model.)
To all whom it may concern:
Be it known that I, EDWARD P. FREDERICK, a citizen of the United States, and a'residen't of the city of St. Louis, in the State of Missouri, have invented a certain neWand useful Improvement in Cable-Strands, of which the following is a full, clear, and exact description, reference being had to the accom panying' drawings, forming a part of this speciication.
My invention relates to an improved construction of strand for wire ropes or cables.
Myinvention consists in features of novelty hereinafter fully described, and pointed out in the claims. I
Figure I is a detail perspective view of a Wire rope or cable made of my improved strands. Fig. II is a transverse section of one of the strands. Fig. III is a detail perspective View of oneof the strands. Fig. .IV is a transverse section of showingY a modification.-
The core of my improved strand is com'- posed in part of a number of Wires l, bunched together so that Where they are cut in cross' section they appear to lie side by side in dou ble column with single Wires 2 at the ends. These Wires land 2 aretwisted together, and they form a solid core of twisted' wires that is oval in transverse section. `When the strand is in use,an equal strain will be brought to bearl uponthe different `Wires of the core, and no t an unequal strain, as is the case-where a num- .ber of wires are coiled about a central untWisted Wire, as is quite common in rope-making.
At each side of the core ot' Wires there is placed a thin ribbon 3, preferablyof metal,
the inner faceot' which is preferably fiat and 'the outersurface slightly rounded, as shovrn` clearly in Fig. III. The Width of each ofthese ribbons is preferably about equal to the .width of the stack of Wires 1. The ribbons form part of the core, and about the core thus formed the outer or covering Wires 4 are laid up and twisted te complete thc strand. A
-Wires without the former one of the strands,.
about a hemp core 5 to form the cable or rope- 6, as shown in Fig. I.
-The ribbons 3 build out .the sides of the core, thereby making a more perfect oval body for the covering-wires to be wound upon. They also permit of the covering-Wires being laid at the saine degree of twist as the corelying in the spaces between the latter. The ribbons also add strength to the strand Without materiallyin- .creasing its size, and they alsoprevcnt lthe Y tendency of the-.cores to dish or become convex on the outer sides when Wound upon the core v5, as has been found to be the case in the absence of the ribbons.
My invention may, in a 1n easure, be carried out by placing a ribbon on one side only of the core-Wires, as'shown in Fig. IV. This ribbon would be placed on what would be'thc outer 'side of the strand when Wound upon the core 5 and it T vill serve to keep the core of the strand from dishiug, as explained.
I claim as my inventionl. In a cable-strand, a core composed of a number of wires and a ribbon placed at one side. of said Wires and lying parallel with the axis of the strand, in combination with c ov- Aeringavires laid uparound'the core, Substantially as set forth.
2. In a cable-strand, a core composed of a number of wires and ribbonsplaccd a't the sides of said Wires and'A lying parallel with the axis of the strand, in combination with covering-Wires laid up around the'core, substantial] y as set forth. 4
3. In a cable-strand, a core composed of a numbery of twisted Wires arrau ged in oval form and ribbons placed at the sides of said wires andchaving dat inneraud rounded outer surfaces, in combination with covering-Wires laid up around the4 core, substantially as set forth.
EDWARD P. FREDERICK.
In presence of* E. S. KNIGHT, N. FINLEY.
