The invention relates to a pole especially designed to meet the need for a pole for radio antenna. or other uses such as atlagl sta The object of the inventionis to'provide a long light pole or mast of exceptional strength; a pole which Amay be usedl in temporary locations, for receiving or broadcasting or ior other purposes; a pole which because of its design and its lightweight may readily and quickly be assembled and raised into position or lowered and u ncoupled for transportation; a pole or mast which may be used where heavy and expensive masts are out 'of the question.
' The construction of the pole can best'be seen and understood'by reference to the drawings in which- 7 Figure 1 shows vthe pole and attached parts in elevation, the pole itself being shown in vertical cross section. f
Fig. 2 is an enlarged detail of a portion of the pole shown in Fig. 1.
Fig. 3 is a section on the line 3-3 of Fig. 2; and
the line 4--4 of Fig. l 1s a section on Fig. 2.
Referring to the drawings The pole comprises parts 1 and 2, respectively7 of which part of the pole and 2 the upper part, the upper part being of less diameter than the lower partand in extension oil it.
Each of the parts of the pole is made up of assembled pipe. sections. 3 represents the outer pipe sections cylindrical in form an connected to one another telescopically by overlapping joints et. 5 are the inner pipe sections which are pressed in to tit snugly within the outer sections. The inner pipe sections are so arranged that aconsiderable lengthot inner p ipe section will overlap the joint between adjacent outer sections, while lesser lengths of inner pipe sections will be employed to complete the reinforcement of the outer sections, washers 6 being interposed between the inner pipe sectiolns of the respective parts oi' the pole.
The size and arrangement of all the pipe sections may bey varied. The particular arrangement shown is one in which in practice the outer pipe sections feet in length. The inner pipe sections 5, which lap by the joint between. adjacent outer sections, are'also ten feet in length,
the part 1 is the .lower 3 are each ten- 'at their bottom ends whilethe remaining inner pipe sections are substantially five eetin length. i
All vof the pipe sections may be made of relatively light weight vmetal similar to that extensively used in rain conductors and such metal is preferably employed. The inner pipe sections are pressed forcibly Within the outer pipe sections, the corrugations in the `inner pipe sections permitting lthese sections to yield slightly' as they are pressed or forced into place. y.Grreat strength is thus obtained even though relatively light metal is employed. y y j The washers 6 between the inner pipe sections prevent these sections as well as theouterv sections from collapsing or pushing together y inasmuch as the Washers impartA lto the inner pole sections the eifect of a continuous pipe and preventthe sections pushing together or telescoping by the down thrust brought to bear upon them by'thepull of the guy wires which lsupport the pole as explained below.
The respective are joined together-and' the part 2 mounted upon the part 1v by means 4of aninterposed butt 7. This butt, preferably made of cast metal, has ahollow body 8- which extends for an appreciable distance down into the top of the lower part 1 of the pole, thebody fitting therein. 9 is a fla-nge extending laterally from the butt at a point just above the top end pole and against which flange the end 1() has bearing. The bottom of the upper part d 2 of the pole extendsvdownwardly to lit 1() of the part lof the within the hollow of thefbutt and the bottom end 11 of this vpart bears lagainst a flange 12 extending inwardly from the butt. The butt thus provided not only acts as a step for connecting different yparts of the pole oi' prevents any telescoping of these parts.
A pole of this kind consisting las it does oi light metal cannot well be embedded in the earth or concrete Yaccordingly it should be held in an upright position by some suitable extraneous means. To' this end the pole is preferably mounted upon a base plate 13 fixed in the earth by a pin 14. The pole isheld in an upright position by means of guy wires 15 connected to anchor plates 16 suitably embedded in the earth in blocks 17 so embedded. Preferably condillerent diameters, but eifectuallyor, as shown,
10o without soon rusting, and N llO neeting With Athe guy Wires are lashings 18 fastened to collars 19e arranged on the pole. At their topen'ds the guy Wires are secured to a cap 20 mounted on the'top'ot the pole, overlapping' the 'adjaee'nt -pip'er 'sec-L tions and forminga protective easing therefor. The cap is held in placeby'va-slianl 2l litting` downwardly Within the adjacent pipe sections. y lVherethepole is used as a flag staff `any other s'u'itablenieans may be provided 'for its support-'as is'custoni'ary in the support f lagfstaiifs. v
