METAL POLE.

My invention relates to a metal pole or post for supporting telephone and telegraph lines or the like, but adapted to be used for any other purpose for which the pole may be found appropriate. It is an object of the in vention to provide a simple and inexpensive pole or post of minimum weight and n1aximum carrying strength, as well as one that will be durable and substantially permanent in use, and by the employment of which numerous disadvantages encountered in the use of poles or posts of wood or other mate rial of like nature will be obviated, all as will be hereinafter more particularly described and claimed.

Referring to the drawings, which are made a part hereof and in which similar reference characters indicate similar parts,

Figure 1 is an elevation of a pole constructed in accordance with my invention, set in the ground, I

Figure 2, a detail perspective of the lower portion of the pole,

Figure 3, a diagrammatic plan view of the top of the the pole, and

Figures 4, 5, and 6, detail views of other forms of members which may be used.

In the drawings a pole or post is shown constructed of a series of members or strands of inverted V-shaped cross-section, a portion of which extend in a spiral direction lengthwise of the pole and another portion extend lengthwise of the pole in a spiral direction reverse to that of the first portion.

In the drawings a group of inside inembers 10 are formed in a spiral which extends from one end of the pole to the opposite end, and a group of outside members 11. which also extend from one end of the pole to the other end, and in a direction opposite the first group. The members of each group cross the members of the opposite group at regular intervals throughout the length of the pole and the edges of the members of one group contact with the edges of the members of the opposite group at such crossing points, as shown in Fig. 3, and form a cross section of substantially diamond shape. The contacting edges are preferably secured together by electric butt-welding at 12, or by any other convenient method. Electrically butt-welding the contiguous edges is much more effective than spot-welding and also much less expensive.

Wide metal bands 13 are provided at the 1927. Serial N0. 196,111.

extremities of the pole between the spiral members 10 and 11 and such bands are pref erably secured in the same manner in which the contiguous edges of the bars are secured. It is also desirable to place a similar wide band 14 at the ground line where the greatest strain is placed upon the pole when in use, since such band reinforces the pole. Also, if

desired, bandsmay be placed at different points along the length of the pole,

lVhile I have illustrated a pole which (on sists of fourteen spirally wound members of particular shape in cross section, a greater or less number or members may be employed and, as illustrated in Figs. 4 to 6, members of different shape may be substituted and. the size may be varied according to the strength and rigidity of pole desired. reason of the special construction of my pole, the particular type of members used, and the manner in which they are secured together inthe spiral form shown, a pole of comparatively small amount of material is provided which is capable of withstanding comparatively great strain, the parts being so positioned that each member sup plemcnts the other in resisting stress and lending strength and stability to the structure.

It will be obvious to those skilled in the art that poles or posts forming the subjectmatter of this invention may be made of any length and size desired and that the members need not necessarily be wound spirally but, on the other hand, a pole of polygonal cross section may be formed to adapt the same for any particular use or purpose and I, therefore, no not limit myself to what is shown in the drawings and described in the specification, but only as set forth in the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A post formed of two groups of spirally disposed members, one group wound right hand and the other group wound left hand, each member having legs whose edges are connected with the edges of the corresponding legs of the other members at crossing points, substantially as set forth.

2. A pole or post comprising two groups of spirally arranged members, the members of one group extending spirally in one direction and having legs presented to legs of the group which extends in an opposite spiral direction at crossing points substantially as set forth.

3. A pole or post comprising two groups .of spirally arranged members, the members of one group extendingspirally in one direction and having legs presented to legs of the group which extends in an opposite" spiral direction at crossing points, said members being connected at crossing points, substantially as set forth.

4. A pole or post comprising a group of members extending from one end of the pole about the same to the opposite end, a second group of members ext-endingfrom one end of the pole about thesamein a direction opposite the first group to the opposite end of the pole, the members of each group presenting. thin leg portions tothe members of the other group, and the thin leg portions of said groups being connected at crossing points, substantially as set forth.

5. A pole or post comprising a group of angle memberswxtcntling Tour one en t of the pole to theoppositend; a second group of angle membersextendiiigfronr one end of the pole in a direction opposite the lust group to the opposite end of the pole, the

members of each group having their angles
