POST.

' Application filed February 3, 1927. Serial No. 165,575.

This invention relates to improvements in poles or posts and particularly to an assem-' bly or" skeleton or open-frame posts in which the spread of the post will provide unusual strength and stability relatively to the amount of material used. Further improvements relate to the details of connecting the web-members of the post to the vertical main or supporting members.

The annexed drawing and the following description set forth in detail certain means embodying my invention, such means constituting, however, but one of the various forms by which the principle of the invention may be illustrated.

In said annexed drawing:

Figure 1 is a perspective view of the im proved post;

Figure 2 is a plan view;

Figure 3c is an enlarged fragmentary perspective, showing in detail the method herein described for connecting the web-members to the main supporting members; and

Figure 4 is a plan view of the elements as shown in Figure 3.

Referring to the annexed drawing in which the same parts are indicated by the same respective ordinals in the several views, I indicate by the ordinal l a plurality of vertical main supporting members, the same as herein shown being three rods assembled in the completed post to form the corners of an equilateral triangle as plainly shown in Figure 2.

These main members 1 are cut to desired length and clamped in suitable assembling mechanism at spaced distances providing the desired spread and are then rigidly eonnected together by tie-bars 5, the latterbeing of a length to reach from one main mem her 1 to an adjacent member 1 in a sloping position, substantially as shown in the accompanying drawing, the adjacent tie-bars 5 being secured to the members 1 with their ends in close proximity, so that the plurality of tie-bars 5 form in eliect a continuous spiral web member 2. In the accompanying drawing, for purposes of illustration, I have shown the web member 2 as encircling the main members 1. and exteriorly crossing or bounding the latter. Horizontally arranged top and bottom strengthening web members 3 and 4 are wrapped about the ends of the members 1 and welded thereto as indicated by the ordinal 11.

In order to secure a strong and rigid connection between the tie-bars 5 forming the continuous spiral web member 2 and the main, members 1 at the points where the spiral web member crosses the member 1, I longitudinally split the tie-bars 5t0. form adjacent pairs of bar sections 5 5 5 and 5", preferably of equal size, illustrated by the enlarged view of Figure 3 wherein one crossing point of the web bar 2 has been developed to show this detail construction and method of uniting the tie-bars to the main supports, the two pairs of split sections, 5 -5 and 5 5*, being bent in opposite directions about the adjacent member 1 and rigidly secured thereto, preferably by welding, as indicated by the ordinal 10. The result of this rigid connecting of the individual tie-bars to the members 1 is to form what is in effect a continuous spiral member 2 transversely cut in the plane 6 at each crossing point upon the main members 1 and rigidly united with the main members 1 at these crossing points, producing a post of comparatively great effective spread which furnishes unusual strength and stability for the amount of material used.

WVhat I claim is: 1.' A post comprising spaced vertical supporting bars, and a spiral web bar bounding said vertical bars from end to end, said web bar being divided into individual tie-bars at its crossing points upon the respective vertical bars and having the adjacent tiebar ends longitudinally split and the respective split sections bent about the respective adjacent vertical bars in opposite directions and rigidly secured thereto, thus forming in effect a continuous web-bar.

2. A post comprising spaced vertical supporting bars, and a. spiral web bar bounding said vertical bars from end to end, said web bar being divided into individual tie-bars at its crossing points upon the respective vertical bars and having the adjacent tie-bar ends longitudinally centrally split and the respective split Sections wrapped about the respective adjacent vertical bars in opposite directions and welded thereto, thus forming in effect a continuous web bar.

3. A post comprising spaced vertical supporting bars, a spiral web bar bounding said vertical bars from end to end, said web bar being divided into individual tie bars at its crossing points upon the respective vertical bars and having the adjacent tie barends longitudinally splitaind the iespective split sections bent about the respective adjacent vertical bars in opposite directions and rigidly secured thereto, thus forming in ef feet a continuous Web bar, and upper and lower horizontal Web bars bounding the ends of said vertical bars.

4. A post comprisiru; spaced. vertical supporting bars, a spiral Web bar encircling said vertical bars from end. to end, said web be! being divided into tie hers in the planes where it cx-teriorliy crosses the respective vertical bars and having the adjacent tie-bar ends longitudinally split and the respective split sections bent about the respective adjacent vertical bars in opposite directions and rigidly secured thereto, time iorming in effect aconitlnuous web, bar, and! upper and lower horizontal web bars bounding the ends of said vertical bars.

5'. A post comprising spaced" vertical supporting bars, and a spiral web-bar bounding said vertical bars from end to end, said webbar being divided into individual tie-bars at its crossinigjpoints upon the respective STANLEY MAOOMBELRL
