Description

Background of the Invention

In the maintenance of underground telephone and other electrical transmission lines it is necessary to connect electrical test equipment and other type equipment into the lines at spaced intervals for various purposes, such as, locating a short, a damaged section, and for other purposes. "Pedestals" located approximately a mile apart and containing wire closures, relays, repeaters and other test elements are used in connection with this maintenance. The pedestals are stake or pole mounted. With the stake mounted type no pole is required, although a stub pole is often set adjacent the stake for added support.

Pedestals for underground electrical transmission lines, which often pass through extensive ranching areas where animals, such as cattle, sheep and pigs are present, must be protected from animals scratching or rubbing on and damaging them. Devices for guarding against animals rubbing against various elements are disclosed in U.S. Pat. Nos. 1,923,858; 3,362,115; 3,400,503 and 3,611,651. A disadvantage of prior art guard devices for protecting electrical pedestals against animal contact is that the guard elements are not removable to permit access of workman to the pedestal.

The protective or guard devices in the patents referred to above take the form of barbs or pointed devices protruding outwardly from a support which is attached to the object to be protected. In the protection of pedestals to which workmen must periodically have access, the protective device interferes with such access. Therefore, there is a need for a removable guard device for pedestals, stub shafts and other post-like support devices.

Accordingly, it is an object of this invention to provide an animal guard assembly for electrical pedestals and support elements for them which is an effective guard against animals rubbing or scratching against them and in which the barbed structure of the assembly can be readily removed to permit access of workmen to the pedestal or support member and replaced in operative arrangement after the work is finished.

Description of the Preferred Embodiments

The invention will now be described with reference to the drawings.

Referring to FIG. 1, showing the animal guard assembly mounted on a stub shaft represented schematically at 10, the guard assembly of the invention is represented generally by the numeral 12 and the barb support element is represented generally by the numeral 14.

Referring to FIGS. 1 and 2, the barb support element 14 is comprised of central support rod 16 having a cap or stop member 18 secured at its top or free end and a lower support plate 20 secured to rod 16 below the cap which also serves as a stop or thrust bearing surface. The cap 18 may be fixedly or removably secured to the free end of the central support rod 16.

Referring to FIG. 2, the barb support element 14 is mounted around the central support rod 16 between the cap 18 and the support plate 20, and lower end plate 24 connected by a plurality of circumferentially spaced vertical guard rods 26 which support a plurality of animal repelling elements or barbs 28 which in this modification take the form of staples. The end plates 22, 24 are each provided with a central hole through which the central support rod 16 is mounted. Tolerance is provided between the holes and the central support rod so that the barb support element is rotatable on the central support rod 16.

Referring again to FIG. 1, for mounting barb support element 14 on a stub shaft 10, a horizontal support arm 30 is provided. The support arm in this modification is an angle iron. The barb support element 14 is affixed at its lower end to the outer end of the support arm 30 by means of extension 32 of rod 16 which is welded to one side of the angle iron as shown.

For attaching the support arm 30 to the stub shaft 10, a base plate 34 is provided for securing to the stub shaft by means of screws or other suitable means. A sleeve member 36 for holding one end of the support arm 30 is welded or otherwise secured to the base plate 34. The dimensions of the horizontal arm 30 are such that its free end will fit snugly into the interior of the sleeve member 36. For removably securing the free end of the support arm 30 into the sleeve member 36, holes 38, 90.degree. apart, are provided in the free end of the support arm which mate with holes 40 (the bottom hole not shown) in the sleeve member 180.degree. apart. The support arm 30 and the sleeve member 36 are locked together after assembly by inserting the pin or bolt 42 through the top hole 40 through either of the holes 38, depending on whether lateral or vertical positioning of the guard assembly is desired, and down through the bottom hole 40 in the sleeve member 36. A threaded bolt and threaded holes 40 can be used.

By the construction shown, the support arm 30 is adjustably attached to the sleeve member 36 so that the barb support element 14 may be supported or positioned in four angular positions, 90.degree. apart, and is readily removable to permit access of workmen to the pedestal it guards. Thus, the barb support element 14 can be positioned as desired to provide the best protection.

Referring to FIG. 3, the upper guard assembly is shown mounted to a pole with the barb supporting member 14 extending upwardly in a vertical position to protect a pole mounted pedestal 43, and the lower guard assembly is shown mounted to a pole with the barb supporting member 14 extending downwardly to protect a pedestal 43 mounted on a stub shaft adjacent a pole.

FIG. 4 shows an assembly in which the support arm 30 is cut at an angle at the end by which it is attached to base plate 34 so that when the base plate is mounted on a pole the support arm 30 will be positioned to the side of a shielded wire under a dome so that the guard element extends in front of the pedestal 43, this being one of the applications of the guard assembly.

FIG. 5 shows the support arm 30 cut at an angle 44 to permit mounting of the barb support element in an orientation like that shown in FIG. 4.

FIG. 6 is a showing similar to that of FIG. 5 in which the numerals 45 and 46 correspond to the numerals 36 and 34, respectively, of FIG. 1.

Obviously, the means for adjustably connecting the horizontal support arm 30 to the sleeve member 36 is only one means for making the adjustable position attachment, as other means could be used. For example, the sleeve member 36 and support arm 30 could be of tubular construction so that the guard assembly unit 12 could be supported in any angular orientation. The guard assembly unit 12 could be of a different construction for serving the purposes of the invention. For example, it could be in the form of a single support rod carrying the barbs. The described configuration has the advantage that the barbs are supported in a manner so that the vertical guard rods supporting them rotate when an animal is rubbing against them and thus minimize the danger of injuring the animal. The barbs 28 can be single barbs or other type structure just so they have sharp points protruding outwardly. Likewise, the guard assembly may be made of steel, plastic or other suitable material, as is well known in the art.

From the above description it is seen that a protective guard assembly has been provided by the invention which is safe for animals, can be mounted to protect an electrical pedestal in practically any location, and in which the barb supporting elements can be removed with the barbs to permit workmen to safely work around the pedestal and replaced after the work is finished.
