pole-or mast unit having the same character 3 above referred to, but with their web porof cross section, but producing a pole or mast possessing a uniform taper throughout its length.

For this purpose,.I have devised. a new method orrproeess of construction, wh'ereby I-beams maybe so cut'and reassembled as to produce a steel pole or mast of the nature described. Infcarrying out this novel meth; od, I cut through the web of the I-beam,

'lengthwise, and along a diagonal line from endto end of the beam, reverse the sections end for end and reunite the severed edges of the web portion of the beam, to produce a permanentconnection and resulting in a pole or mast of the desired tapered form.

It is also sought to provide a novel pole or mast construction in which the same is.

not limited to a single web portion, but may be produced by a plurality of I-beams' cut.

diagonallyand reassembled in the manner tions in intersecting relation. 7

With the foregoing general objects in view, the invention will now be described by reference to the accompanying drawing, illustrating both the improved pole construc tion and process of making the same, after which the novel features therein will be particularly set forth and claimed.

portions in reversed relation; and Figure 8 is a sectional view illustrating a steel pole or mast construction made up of a pair of I-beams in the fashion shown in Figures 1 and 5, but with their web portions united in intersecting relation.

Referring now to ,the drawin in detail Figures 2 and 3 illustrate t e character of I-beam which is used for constructing the tapered form of steel pole or mast forming the subject of the invention. The first step in the'method of producing this new mast construction is the cutting of the web portion 10 of the I-beam' along a diagonal line, as indicated at 11,-

whereby two duplicate tapered I-beam sections 10'. are produced, as illustrated in Figure 4. The next step of the process is simply the reversal of these I-beam sections 10',

end for end, bringing the cut-edges 11 again into abutting relation, as illustrated in Figures 1 and '5, after which the edges 11 of the sections 10 are permanently soldered or welded together by any suitable and prac tical means well known for this purpose.

This method or process obvlously .pro-

(lines a practical and eflicient form of steel pole or mast unit, which is of the desired tapered form or outline, and possesses all the requisite strength and rigidity for its use as a pole ortower structure, due to the I-beam form of cross section as shown in Figure 5. The method of producing this type of unit is of an extremely simple and economical nature, and adapted to be carried out in a practical manner in shops designed generally for this class of work.

. After the welding of the sections 10 in their final form as illustrated in Figure 1, the resulting pole or mast section may be suitably punched, as illustrated at 12, to

produce a series of steps designed for use in the usual manner for enabhng the workmen to ascend to the top of the tower.

In Figures 6 and 7 is illustrated a modified form of construction, .due to the use of a slightly different method of producing the cut for seven'ng the I-beam. In this modified method, a slightly inclined shearing out space 14 is produced between the bevelededges 11', along the line of out, which is desirable in some instances as afiording-a more ample space for the application of the welding material, as, will be readily understood.

In' Figure -8, I illustrate a construction 4 which makes use of a plurality of the the exception that after the I-beam, which are cut and finally reassembled in the manner above ex lained, with rst unit has been reassembled with the cut portions of the beam in reversed relation, as shown in Figures 1 and 5, the second beam is ar-' ranged in the same manner but onopposite sides of the reconstructed first beam, and permanently connected thereto in this-manher, with the final result that the severed parts of both beams have their web portions united alon substantially a common line, and with a parts of both beams tapering in the same direction. This obviously produces a steel pole or mast unit having multiple projections or lobe portions extending out from a common center, and thus afiord-.

ing a correspondingly higher degree of strength, rigidity and firmness of construction.

It is thus apparent thatI have provided a highly eflicient and racticalform of pole or mast construction or tow'er work, which constitutes a material advance or improvement over the type of construction generally used by virtue of the practically continuous web portion of the structure in lieu of the more orless open work which characterizes the prevailing type of tower unit.

Having described the invention, what I claim to be new and desire to secure by Letters'Patent, is:v

1. A steel pole or mast of intersecting I-beam cross-section and having web portions of substantially continuous and uniformly tapered form from one end of the pole to the other'and intersecting with each other along the thereof.

2. The method of constructing a tapered steel pole or mast from an I-beam, which consists in cutting the I-beam lengthwise by a diagonal cut through its web portion, and at an angle to the plane of said web portion, reassembling the severed parts in endwise reversed relation, whereby a V-shaped groove is provided along the edges produced by the cutting action, and securing said parts together by the application of welding material valong said groove. 1

3. The method of constructing a tapered steel ole or mast from I-beams, which consists 1n cutting said beams lengthwise by diagonal cuts through their we poi'tions, and reassembling the severed parts of the beams anduniting the web portions along a common line with all said parts tapering in the same direction.

In witness whereof I signature.
