SPECIFICATION forming part of Letters Patent No. 774,355, dated November 8, 1904.

Application filed April 13,1904.

To all 71/72/0720 if puny concern.-

Be it known that I, WVILLIAMK. GIVEN, a citizen of the United States, residing at Pitts- .burg, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Posts, of which the following is a specification.

My invention relates to metallic posts constructed in substantially all their parts of wire. I contemplate making an open framework of wire in which the faces shall all be trusses capable of withstanding any possible loads exerted in their planes; but the cross-section of the framework may be curved. I contemplate combining these faces so their faces in cross-section shall be a geometrical figure. Each face when the crosssection is angular being a truss and each truss being joined at its edges rigidly to two adjacent trusses, there is no danger of the posts moving in the planes of any of their faces. I provide braces across alternate or other posts to maintain the crosssection of the posts unaltered.

Referring to the drawings, Figure 1 is an elevation of one selected form of my improved posts, the same being shown set in the ground. Fig. 2 is an enlarged elevation of the upper end of Fig. 1. Fig. 3 is a perspective of the upper part of Fig. 2 looking obliquely downward. Fig. I is a View showing the manner in which the trusses of which my posts are constructed are braced.

I will now describe my invention in detail, using reference characters, like characters indicating like parts on the several figures.

The posts which I have chosen to illustrate have four upright corner strips or wires 1, 2, 8, and I, which extend the whole length of the posts. At the top ends of the corner-strips or at some other selected points I secure eight wires 5 6 7, &c., and wind these spirally about the corner-strips from one end of the latter to the other. I preferably wind these wires symmetrically, as shown on Figs. 1, 2, and 3, and have the wires on each face pass diagonally to the right and left and cross each other midway between the corner-strips of 'that face, as shown at 13. I also, preferably,

have the wires which pass from one face to Serial No. 202,924:- (No model.)

the adjacent face cross each other at their crossings of the corner-strips, as shown at 14. I propose to secure together all the wires which cross each other and preferably do this by electrically welding them at the crossingpoints. Thus the winding wires would be welded together at the points 13 and also together and with the corner-wires 1 at the points 14.

In order to brace the several faces or trusses so as to preserve the cross-section of the posts, I cross-connect the alternate or other cornerwires not adjacent by means of wires 15, which cross each other at the point 16. I also, preferably, at the same horizontal position with the cross-wires 15 wind the wire 17 horizontally about the post, as shown particularly on Figs. 3 and 4. As shown on Figs. 2 to 4:, the wires 15 and 17 are shown to be compound or composed of a plurality of wires twisted together; but I do not wish to be confined to this particular construction, as a single plain wire might serve acceptably.

The horizontal bracing- wires 15 and 17 are placed preferably at the top and bottom of the posts and at suitable intervals therebetween, as shown on Fig. 1.

I do not limit myself to any number of the horizontal bracings or to their use at any specific position shown on the drawings.

I do not desire to be restricted to any particular size of wire for use in the several parts of my posts, and, in fact, the corner-strips might be made of material, if desired, which might be understood by .some persons to be too large to be designated wire. I do not restrict myself to any definite cross-section of my posts. all cases to secure together all of the wires or strips where they cross.

As shown in Fig. 1, the post is set in the ground in the ordinary way. The post being constructed of open-work is surrounded and filled between its sides with earth or other suitable material which not only prevents any lateral motion of the post in the ground, but also securely anchors it from being lifted by frost or other agency. The part of the post which is in the ground may be coated with or It might not be necessary in incased by any desired material which will prevent it from oxidation or other Waste or injury.

The spirally-Wound Wires may vary in numher. For example, the number on some of the sides may be omitted. The corner-Wires may be Wound with only two, four, or six Wires or any other selected number.

Having described my invention, What I claim is 1. A post constructed of single upright Wires and a plurality of Wires Wound spirally around the same in difierent directions, the upright Wires and the spiral Wires being secured together rigidly.

2. A post constructed of upright Wires and a plurality of crossing Wires Wound spirally around the same, the Wires having a plurality of their crossings secured together by Welding.
