posts or poles, more particularly telephone,

telegraph, electric light or similar poles, and it has for its object to provide a construction on able of withstanding the destructive e ects of moisture and the elements and which shall be strong and durable for the purpose intended.

The invention consists of a cement or concrete base set in the earth and rojecting above the surface thereof to provit ea pedestal, combined with an upper pole of wood or other material, with strengthening or anchoring rods embedded in the concrete base and connected with the pole to firmly anchor it to said base, with an additional surrounding covering, as shall be more fully hereinafter described.

Referring to the drawings: Figure 1 is a view in elevation of the base portion and a portion of the attached pole, portions of some of the anchoring rods being exposed. Fig. 2 is a vertical sectional view of Fig. 1. Figs. 3 and 4 are cross sectional views on the lines III. III. and 1V. IV. of F-igsl and 2 res eetively. Fig 5 is a sectional detail view i ustrating the use of a tightening wedge.

In the drawings, 2 represents the base of concrete or cement set within a receiving hole in the ground around an annularly arranged series of vertical anchoring rods 3, of steel or iron, of any suitable form ada ted to make holding engagement with the ase 2. Said base is continued upwardly beyond the ground level as indicated at 2 for any desired distance, withina suitable removable forming mold, and finished oil referably with a flat top 4 and beveled e ges 5, although any other suitable form may be given to the top of the. base to adapt it to receive. the pole 6. The particular advantage of the bevel 5 is that the lower edge of the shell 9 more tightly embraces the base 2. The anchoring rods 3 are extended u wardly through and beyond the upper en of the base 2' as shown at 7 for a suitable distance and terminate in any suitable form for attachment to the pole as inwardly turned ti s orextrcmities S.

trennties 8 are driven into the )ole as shown in Figs. 1 and 2 or eonnecte. to it in any other suitable manner, thereby firmly connecting the pole and base together.

An outer covering 9 of concrete or cement is then formed around the holdim ends of the anchoring rods, firmly embedding them, embracing the base of the pole, and etl'ectus ally connecting it within a permanent up-.

wardly extending concrete shell to the main base. Said outer covering may conveniently be molded withm any slut-able outer mold 'hen the pole 6 is firm y. set upon the top of the concrete base, the ex-j Patented Feb. 4, 1908.

or shell and preferably tapers upwardly asshown,.giving a good tinis led a pearance.

When desired, the pole 6 may )0 tightened or adjusted to vertical or any desired inclined position bythe insertion of wedges 10 between the bottom of the pole and top of the r base 2' as shown in Fig. 5, the tension of the rod terminals 7 being thereby increased and absorbing all intervening clearance. By

such means the pole maybe rigidly set upon v the base in the desired position and fixedly attached thereto before application of the surrounding shell 9. Fig. 5 also shows at the left side one of the anchoring rod terminals 9 in its original position before being driven into the pole. i

The advantages of my invention will be 1 readily a preciated by al hose familiar with the use 0 poles.

Ordinarily wooden poles set directl into the ground became decayed at the sur ace of the ground when exposed to the destructive effect of the elements, and their life and efficiency is thus proportionally reduced.

By my invention the base of the wooden pole, being entirely above the ground and protected by the inclosing shell 9, is not sub- 7 Ject to deterioration, while the renewal of posts due to breakage or other injury is rendered easy and cheap by merely removi the shell 9, disconnecting terminals 7 an inserting a new post.

Likewise, old posts may becut ofl' above ground and then mount ed on concrete bases without sacrificing any of their necessarv height.

The number, orm and arrangement of the anchoring rods is within the ogment of the builder, and 1 preferably maire the terminals 7 of varying length as shown in Figs. 1 and thus staggerim their points of eetachmen to the pole, to insure the best results.

g l l Other changes or variations may he made by the skilled mechanic without departing from the scope of the following claims:

What I claim is: w
