Opinion of the Court
delivered the opinion of the Court:
Appeal from a decision of the Patent Office denying the following claims:
“1. An article oí manufacture consisting’ of a flexible rope socket comprising’ a solid metal base and a flexible wire-rope loop, the ends of the loop being permanently secured to the base.
“2. A flexible coupling for wire rope consisting of a pair of linked sockets formed of flexible wire-rope loops and socket bases of solid metal, each of the loops having its ends permanently attached to its individual socket base.
“J. In combination, wire ropes and a flexible insulating coupling comprising a pair of linked sockets formed of flexible wire-rope loops and socket bases of solid metal to which bases the ropes are secured, each of the loops having its ends permanently attached to its individual socket base, and an insulator inserted between the flexible loops to form a mechanical connection between the sockets and to insulate them from one another.
In combination, wore ropes and a flexible coupling comprising a pair of linked sockets formed of flexible wire-rope loops and socket bases of solid metal to which bases the ropes are secured, each of the loops having its ends permanently attached to its individual socket base, and a block having grooves at right angles for receiving the loops and inserted between the flexible loops to form a mechanical connection between the sockets.”
'The invention, according to appellant's specification, “relates generally to couplings for stay wires and the like, with particular reference to stays used in connection with aerial wireless towers which are generally insulated from the earth.” The specification further sets forth that one object of the inven
Appellant’s device may be described as two interlocking wire-rope loops separated by an insulator, such as porcelain, the ends of the ropes being permanently attached and the entire device being merely an insulated link in a stay. In other words, this insulated link in the stay, for purposes of illustration, may be likened to a swivel in a chain.
The patent to Hill (No. 929,132, dated July 27, 1909) covers an insulator designed primarily for suspending trolley wires, electric cables, or other conductors from the under side of structures of any sort. The most approved type described by Hill differs from appellant’s device in that it lacks flexibility. In Hill’s figure 4-, however, the loops or short pieces of cable are passed through the insulating body in practically the same way that appellant’s loops are passed through it, and the ends of the loops are permanently attached like those of appellant. It is apparent, however, that Hill was not seeking flexibility, and his loops are too short, even in figure 4, to admit of it. But, as pointed out by the Patent Office, anyone familiar with the art who was seeking a flexible insulator of the ITill type would have had no difficulty in constructing such a device, by combining the Hill and the Fletcher or Jobson device's. The Fletcher patent (No. 1,028,104, and dated Juno 4, 1912) relates to a strain insulator in a stay or guy wire, as does appellant’s device, the only difference between the two devices being
We conclude, therefore, as did the Patent Office, that appellant's efforts did not rise to the dignity of invention. Any good mechanic, by referring to the patents cited, could have produced the same result.
The decision is affirmed. Affirmed.
