Patent Issued for Cable Hoist and Bracket System and Method

August 13, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Preformed Line Products Company (Mayfield Village, OH) has been issued patent number 8789815, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Deel, Adam (North Olmsted, OH); Cloud, Randy G. (Mentor, OH).

This patent was filed on September 22, 2010 and was published online on July 29, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "An optical fiber is a glass or plastic fiber designed to guide light down its length by total internal reflection. Although fibers can be made out of transparent plastic or glass, most often, fibers used in long-distance telecommunications applications are glass, due to a lower optical attenuation. Both multi-mode and single-mode fibers are used in communications, with multi-mode fiber used mostly for short distances and single-mode fiber used for longer distance links. Oftentimes, these fibers are used in communication which permits digital data transmission over longer distances and at higher data rates than electronic communication.

"In communication service provider applications, optical fibers are bundled as cables. Because light propagates through the fiber with little attenuation compared to electrical cables, use of fiber optic cables is especially advantageous for long-distance communications. By using optical fiber cables, long distances can be spanned with few repeaters. Additionally, the per-channel light signals propagating in the fiber can be modulated at substantially higher rates than conventional coaxial cables.

"Today, optical fibers are becoming more and more common as a medium for networking and telecommunications. For example, television and Internet service providers are using fiber optics to deliver their services to customers in homes, multi-residence buildings and office buildings. Unfortunately, many of these structures are older which makes installation sometimes cumbersome and costly as, many times, optical cables must be fed through a structure's existing plumbing, electrical and heating ducts."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "The following presents a simplified summary of the innovation in order to provide a basic understanding of some aspects of the innovation. This summary is not an extensive overview of the innovation. It is not intended to identify key/critical elements of the innovation or to delineate the scope of the innovation. Its sole purpose is to present some concepts of the innovation in a simplified form as a prelude to the more detailed description that is presented later.

"The innovation disclosed and claimed herein, in one aspect thereof, comprises systems and methods that enable a cable to be easily terminated at an elevated level. For example, the cable can be a strength member having a number of fiber optic storage loops disposed about its length. It will be understood that these loops can be strategically positioned upon a sidewall of a structure (e.g., multi-dwelling building) such that fiber optic service can be efficiently connected as desired. The innovation can employ a bracketing assembly that mounts a hoist apparatus upon a surface such as a knee wall of a rooftop. Variable and adjustable bracket assemblies are provided to accommodate most any surface mounting scenario.

"In an aspect, the system includes a housing having a locking cavity where the cable can be terminated. The housing includes entry and exit apertures that permit a pulling device to pass through, e.g., pulling tape from ground level. A locking mechanism can be positioned within the housing which engages a dead-end device connected to the cable thereby facilitating termination of the dead-end device at the elevated level.

"Upon engagement, the dead-end device enables removal of the pulling device from ground level. For example, the pulling device can be a pulling tape or rope. In one aspect, the pulling tape (or rope) can be installed into hoist mechanism by, for example, establishing a knot on one end of the pulling tape, wherein the knot can be secured within the housing of the hoist mechanism. The pulling tape can be threaded or loaded such that a loop terminated by the knot can be threaded through the hoist mechanism. An opposing length of the pulling tape (opposite the knot) can be threaded through the hoist mechanism and dropped to ground level along with a loop. The opposing length can facilitate pulling the looped end to hoist height, thereby locking or engaging a dead-end device into the hoist mechanism. Engagement can be accomplished by way of a locking mechanism such as a free-floating locking pin. The pin can be constructed of galvanized or stainless steel.

"In one aspect, the dead-end device can be a helically wound wire device having at least two loops, wherein a pulling mechanism is attached to one of the loops and the other of the loops engages with the locking mechanism. The dual loops facilitate ease of removal of the pulling mechanism from ground level.

"In other aspects, the dead-end device is a spring loop wedge cap that includes a plurality of wedge blocks that grip the cable and a spring loop that facilitates engagement with the locking mechanism. The spring loop can include a secondary loop configured for installation by and removal of the pulling mechanism. The spring loop can alternatively employ a crimp loop that is attached to the top of the spring loop and provides a secondary loop configured for installation by and removal of the pulling mechanism.

"In still other aspects, the dead-end device can be a tapered wedge cap having a hooking mechanism that facilitates installation by and removal of the pulling mechanism. In this aspect, the locking mechanism can include a plurality of spring clips that compress upon insertion and lock once in position at termination.

"To the accomplishment of the foregoing and related ends, certain illustrative aspects of the innovation are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles of the innovation can be employed and the subject innovation is intended to include all such aspects and their equivalents. Other advantages and novel features of the innovation will become apparent from the following detailed description of the innovation when considered in conjunction with the drawings."
