This invention relates to a novel and improved cable spacer adapted for use in connection with a lead covered aerial cable which, in practice, is
lashed against displacement to the supporting snugly on the aerialeable, has-a channeled blocktype riser in whichthe suspension strand is partly saddled andis otherwise fashioned and made to accommodate an embracing and retaining band. Thusconstructed and, when securely strapped in-place, thespacer takes-aposition from 6" to 10" from the center of the usual pole and consequently functions to keep the lead sheath of the cable spaced away from the hard metal suspension clamp at the pole, the clamp which is commonly used to hang and anchor the stated suspension strand.
It is common practice in this line of endeavor to hang an aerial cable from a clamp attached suspension strand, and to avoid chafing and undue wear of the lead sheath from wiping and rubbing contact with the pole clamp, different types of spacers are interposed between the cable and suspension strand. In carrying out the prin ciples of the instant invention, and with a View toward incorporating needed refinements and betterments, I have evolved and produced a spacer of the stated kind, the same being made of lead, whereby to attain the wanted ends to best advantage.
Then, too, novelty has to do, it is believed, with the adoption and use of a lead spacer having the form and facilities above mentioned along with a metal binding strap or band which, being looped and clamped securely, serves to accommodate the lashing wire, whereby to insure against undesirable shifting and displacement of the spacer.
Other objects, features and advantages will become more readily apparent from the following description and the accompanying illustrative drawing.
In the drawings, wherein like numerals are employed to designate like parts throughout the views:
Figure l is a fragmentary elevational view showing a lead sheathed cable, suspension, strand therefor, clamp for attaching the strand to a pole, improved spacers constructed in accordance with this invention and coiled lashing wire on the strand and connected with the spacers;
Figure 2 is a perspective view of the spacer per se;
Figure 3 is a cross section, on an enlarged scale, on the line 3-3 of Figure 4, looking in the direction of the arrows; and
Figure 4 is a longitudinal sectional .view on the line 4--4 of Figure 3, also looking in the direction of the arrows.
Referring now to the drawings by reference numerals and lead lines the relatively stationary or fixed post or pole is denoted by the numeral 6 and attached thereto is a conventional type clamp which serves to mount the conventional type suspension strand 8, the latter being used, as is customary in the field to support the lead covered or sheathed aerial cable 9. incidentally in Figure l whereinthese details are shown'it will be seen that I have illustrated sufiicient of the old structure to enable those skilled in the art to understand the improved spacing means and other details directly associable therewith. As shown in Figure 1, the spacer assemblies are arranged at longitudinally spaced points in relation to the parts 8 and 9 and also are spaced on opposite sides of the supporting pole 6. Each spacer unit is the same in construction and the description of one will sufilce for both. In Figure 2 the spacer, which is made of lead, is denoted by the numeral I0 and embodies a one-piece body characterized by a semi-cylindrical adapter or rider II. This is proportioned and shaped to conform to the upper half portion of the cable 9 on which it is seated. At opposite ends and on opposite sides I provide outstanding lugs l2 and I 3. The pairs of lugs on each side define notches between themselves as at 14 to accommodate a fastening and clamping band I5 of metal or other suitable material. Mounted on the central crown portion of the adapter is a block-like riser [6 whose upper surface is formed with a shallow groove l1 forming a suitable seat for the lower half portion of the suspension strand 8. In Figure 3 I show how the adapter fits firmly on the cable and how the riser accommodates the strand 8.
The strapping and clamping band I5 is adapted to encircle and loop around the bottom half of the cable and over the top half of the suspension strand, as brought out in Figure 3. The width of the strap is such that lower portions of the loop rest in the notches l4 where they are kept securely in place. The free ends of the strap are bent upon themselves as at 18 and I9, respectively, and a suitable horseshoe clip or the like 20 is fitted into the bent end portions to secure same together. In connection with the showin of features l8, l9 and 20, in Figure 3, it is to be understood, of course, that other ways and means of connecting the band ends may be employed so that said ends may be interlocked and clenched or some other type of seam may be utilized. In any event a band is wrapped or looped around the cable and strand and mechanically connected with the spacer and thus the spacer is appropriately fastened on the cable. As a further precaution, however, a lashing wire 2| is employed and this is coiled around the strand 8 and portions thereof as at 22 are laced through the strap or band 15. Thus the spacers are securely lashed to the strand to guard against longitudinal slippage and displacement.
In practice the lead spacers are interposed between the strand 8 and cable 9 and preferably situated some 6 to 10" on each side of the approximate center of the pole 6 as shown in the assemblage seen in Figure 1. When the spacers are strapped in place by the band and lashed to the strand 8 for anchorage, they serve, obviously, to provide and maintain a space between the pole clamp l and the underlying lead covered cable 9, thus protecting and prolonging the life of the cable.
A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.
Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.
Having described the invention, what is claimed as new is:
In a structural assemblage of the class shown and described, in combination, a suspension strand, a clamp adapted to connect said strand to a pole, a lead covered cable beneath and approximately parallel to said suspension strand, lead spacers interposed between said strand and cable, said spacers being spaced longitudinally from each other and being adapted to be located short distances from said pole, a metal strap looped and wrapped tightly around each spacer and coacting portions of said cable and strand, and separate wires having portions adapted to be wrapped around said strand on opposite sides of said pole and having end portions laced through the looped straps in a manner to lash and anchor the spacers, by way of the coasting spacers and straps, to said suspension strand.
