WAYNE RAWLEY, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR T BLAW-KNOX COM- PANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF NEW JERSEY.

Application filed August 5, 1925.

The present invention relates to supports for poles, such as telegraph poles, and has for its object to provide a support adapted to be applied either to a pole which is rotting 5 at the ground line without having to disturb the portion in the ground, or to a new pole to support the latter without embedding it in the ground at all.

In the accompanying drawings Figure 1 is a side elevation of one form of support embodying my invention applied to a pole having its lower end buried in the ground, the pole in this view being shown broken away below the ground line and above the upper end of the support;

Figure 2 is a sectional view through the pole looking down on the support, a portion of the latter being broken away;

Figure 3 is a View similar to Figure 1 showing a slight modification; and

Figure a is a sectional view through the pole looking down on the support shown in Figure 3, the support being partly broken away.

Referring to the construction shown in Figures 1 and 2, the support comprises upper and lower clamping bands 2 and 3 which are applied to the lower portion of the pole 4, the lower clamping band preferably being applied immediately above the ground. line G. Each band may be made in two approximate ly semi-circular parts having flanges 5 at their ends through which the clamping bolts 6 are passed. The lower clamping band has four small angle pieces 7 bolted to the same and bolted to these small angle pieces are the inner ends of horizontal angle irons 8 which extend radially outwardly from the lower clamping band and have their outer end portions bearing upon the upper ends of concrete anchors 9 embedded in the earth. A diagonal angle bar 10 extends from the outer end of each horizontal angle iron 8 to the upper clamping band 2. These diagonal angle bars have their portions bent so as to adapt them to be secured to the angle irons 8 and upper clamping band respectively, as illustrated in Figure 1. An anchor rod 11 is embedded in each concrete anchor 9 and has its upper end screw threaded and passed through an opening in the horizontal flange of each angle iron pieces 8 and through the corresponding horizontal flange of the bent portion of the diagonal angle bar 10, and a Serial No. 48,262.

nut 12 is mounted on said screw threaded end for securing the angle iron pieces 8 and 10 to the upper end of the concrete anchor.

In the form of the invention shown in Figures 3 and 4, the concrete anchors 9 have their upper ends positioned somewhat below the ground line G. In this form of the invention the lower clamping band 3 is positioned immediately above the ground line and inclined angle iron pieces 8 extend from the small angle pieces 7 and have their outer ends bearing upon the upper ends of the concrete anchors 9. Inclined angle bars 10 extend from the upper clamping band 2 and have their lower bent end portions bolted to the outer end portions of the angle irons 8. These end portions of the angle irons 8 and 10 are secured to the upper ends of the concrete anchors 9 by the anchor rods 11. Of course, the lower clamping band need not be positioned entirely above the ground line, but this is preferable as rotting of the pole usually takes place most rapidly at. the ground line, so that it is desirable to engage the pole above the ground line.

While in both forms of the invention illustrated the support is applied to a pole having its lower end portion buried in the ground, these supports may also be employed for supporting a new pole without burying its lower end in the ground.

While I have shown and described two preiterred embodiments of my invention, it will be understood that the invention is not limited to the details of construction shown but that it may be otherwise embodied within the scope of the appended claim without departing from the spirit of the invention.

I claim:

A pole support including a sectional upper collar, a plurality of diagonally ext-ending angle iron braces secured thereto, a sectional lower collar having a plurality of connector pieces thereon, and a laterally extending angle bar secured to each connector piece, said diagonal angle iron braces being secured to the laterally extending angle iron braces, there being a lateral brace for each diagonal brace, and anchor engaging means on the lateral braces, said support being applicable to a pole erected in the earth.

In testimony whereof I have hereunto set my hand. WAYNE RAWLEY.
