3 Claims. (Cl. 174- 45) This invention relates to utility wire masts, and, more specifically, it relates to electric and telephone wire masts of the type anchored into the ground or the like,

It is an object of this invention to provide a utility service wire mast which is accurately, easily, and readily installed with a minimum of time and expense and which is inexpensive to manufacture.

Another object of this invention is to provide a service wire mast which is sufiiciently high and sturdy to comply with the requirements of electrical codes and which is simultaneously compact and light for handling.

Still another object of this invention is to provide a utility service wire mast which readily permits varying' the height of the mast in the installed position.

Other objects and advantages will become apparent upon reading the following description in conjunction with the accompanying drawings, wherein;

Fig. 1 is a side elevation view of an embodiment of this invention installed in the ground.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a side elevational view of a part of the embodiment shown in Fig. 1.

Fig. 4 is a side elevational partially sectioned view of an embodiment of the invention shown associated with an outdoor structure such as a telephone booth,

Similar reference numerals refer to similar parts throughout the several views.

Fig. 1 shows a mast anchored in the ground G to project thereabove to the height required by electrical codes. An important feature of the invention is the manner and means of erecting the mast 10 in the ground. As shown in Figs. 1, 2', and 3, a ground sleeve 11 is tubular in form with an arrow-head or wedge-shaped lower end 1 2. Further, the end 12 is flared as shown in Figs. 1, 2, and 3 and it thus is sufficiently pointed to easily penetrate the ground without requiring that a hole be previously dug. With this shaped end, the sleeve 11 can be driven into the ground in a most accurate position to be vertical. To facilitate driving the sleeve 11 into the ground, Fig. 3 shows a driving lug 13 which is shouldered at the upper end 14 to span the diameter of the sleeve 11 while the lower end 16 of the lug is reduced to fit into the sleeve. 6 Thus, the top of the lug 13 can be hammered without bending or otherwise damaging the sleeve 11.

When the sleeve is driven into the ground, an insert tube or spacer pipe 16 is snugly telescopically positioned within the sleeve to extend vertically thereabove. It is preferred in this embodiment that the insert 16 rest in the tapered bottom end of the sleeve 11 as shown in Fig. 2 so that the sleeve lower end provides a stop for the insert 16 to effect horizontally aligned stop-engaging surfaces. An upper unit, generally designated 17, is snugly telescopically positioned over the tube 16 and a bolt 18 is passed through horizontally aligned diametrical holes in the lower end of the unit 17 and the upper end of the tube 16 to secure them together. The unit 17 Patented Mar. 28, 1961 consists of a tube 21 having several of the usual electrical insulators 22 attached to the top thereof, in any suitable manner, and a meter 23 and a breaker assembly box 24 attached to the bottom thereof. Supporting straps 26 are preferably attached between the tube 21 and the meter 23 and the box 24 to support the two latter parts on the mast. Also attached to the unit 17 is a vertically disposed conduit 27 which is suitably afiixed at the top and the bottom of the tube 21 by

straps

28 and 29. It is preferred that all of the straps be welded to the tube 21. The upper end of the conduit 27 contains the usual electric entrance head 31. It should thus be understood that the unit 17 supports a plurality of wires (shown in Fig. 2) which are attached at the insulators 22. The wires are also connected through the entrance head 31 and the conduit 27 to the meter 23 and the box 24. An outlet box 32 is shown at the bottom of the conduit 27.

To complete the support of the mast, Fig. 1 shows a pair of braces 33 which are suitably anchored to the ground at their lower ends and they are attached to the unit 17 through the bolt 18. The braces 33 are inclined with respect to the mast and they are disposed substantially in line with the wires supported on the mast, to deviate from the vertical plane of the wire by the slight angle of the brace with the tube 16, as shown in Fig, 1, and the braces and the wires are preferably on the same side of the mast, as shown in Fig. 2.

Fig. 4 shows a mast of this invention mounted in the ground next to a telephone booth 36 or the like. In this instance, the top of a ground sleeve 37 is shown to project above the ground and it telescopically receives an insert tube 38. The lower end of the sleeve 37 is provided with the pointed flared end 35 for readily penetrating the ground and securing the sleeve there. The sleeve 37 and the tube 38 are secured together by a bolt 39, or the like, which passes through horizontally aligned holes in the two members and the ends of the members abut. An upper mast tube 41 is telescoped over the insert 38 to extend beyond the upper end thereof, as shown, and to connect thereto at the lower end by a bolt 42, in the usual manner. A second insert tube 43 is telescoped within the tube 41 to extend thereabove and the two are connected by a bolt 44. Then an upper mast tube 46 is telescoped over the insert 43 and is bolted thereto by a bolt 47 with the ends of tubes 41 and 46 abutting. A brace 48 is attached between the mast 46 and the structure 36 to further secure the units in vertical position. Connecting straps'49 are attached to the tube 46, by welding or the like, and they extend horizontally therefrom to support the

conduits

51 and 52. Also, the mast 46 contains the previously mentioned entrance head, insulators, and two

conduits

51 and 52 leading to the structure 36 from the top of the mast. This arrangement permits the attaching of electric wires and telephone wires to the booth 36. With this arrangement, the height of the mast can be varied by placing longer sections of inserts and tubes in the mast structure.

While specific embodiments of this invention have been shown and described, it should be obvious that certain changes can be made within the scope thereof, and the invention should, therefore, be limited only by the appended claims.
