the action of the elements for an indefinite 'period.

A further object of 'the invention is to provide a sup orting' base or foundation in which the,el ements of decay and shrinkage 'shall be positively ehminated, thereby to -to increase t firmly support the pole in a vertical position .and prevent excessive vibration of the same.

A still further object of the invention is to generallyirn rove this class of devices so as ciency, as well as, to reduce the cost of-manufacture.

With these and other objects in view the invention consists'in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanyingdrawings, it being understood that vario changes in form, proportions, and minor etails of construction ma be resorted to within the scope of the appen 5 ed claims.

In the accompanying drawings, forming a part of this, specification, Figure 1 is a perspective view of a telegraph-pole constructed in accordance with my invention. Fig. 2 is a perspective view of the intersecting anchoring-plates detached. Fig. 3 is a transverse sectional view showing the manner of attaching the'superstructure or pole to the anchoring-plates. Fig. 4 is an enlar ed transverse sectional view of the termina cap.

Similar numerals of reference indicate corresponding parts in all of the figures of the dr WlDfiS.

The evice consists of a supportin -base 5,

preferably rectan ular in shape an formed which will efiectually withstand I eir utility, durability, and efli-' bolts of other suitable fastening devices 9, and each plate is preferably formed with an elongated slot or o ening 1 0, adapted to engage the side we s of. adjacent plate,.

; verge toward t e top of the structure, as by a terminal cap 12..

shown, and are unite The longitudinal bars 11 are s aced apart by transverse bars 12, and two 0 the longitudinal bars are preferably connected by a luralpreferably ity of transverse strips 13 to form a adder,

so that a lineman or other person may conveniently mount the ole. Mounted on the cap 12 and secured t ereto in any suitable or beam 15, carrying suitable insulators 16 for supporting the overhead wires or con: ductors, as shown.

As a means for rigidly securing the pole or superstructure ,on the anchoring-plates 8, suitable wedge-shaped blocks 17 are interposed between the walls of said plates and the interior walls of the adjacent angle-irons, the parts being rigidly secured together by bolts or rivets 18, as shown. The base 5 and anchoring-plates 8 are preferably covered with a coating of coal-tar in order to preserve and protect the same, said base and plates being embedded or otherwise anchored in the ground, either by tamping the earth aroundthe same or by forming a speciallyprepared bed or opening in the subsequently filling the latter with cement, concrete, or other suitable material.

Any number of cross-arms may be mounted on the terminal cap of the pole, and, if desired, said cross-arms may also be bolted or 100 manner, as by pins or bolts 14, is a cross arm ound and 9 5 50 of cast-iron or other suitable material, said plate being provided with spaced upstanding ribs or flanges 6, adapted to receive and support the intersect vertically-disposed anchoring-plates 8. he plates 8 are de- 55 tachably secured to the ribs 6 by means of caused to snugly engage the anchoringlates, while by reason of the wedge-shaped locks 17 a broader bearing-surface is obtained for engagement with t e attaching-bolts. Attention is also called to the fact that by having the anchoring-plates detachably secured r10 to each other and to the supporting-base the anchoring element of the superstructure may be quickly assembled and alsorea dilyknocked down and compactly stored for transportation or shipment.

The anchoring-plates of the base are preferably reinforced and strengthened by su1t-.

able 'bars or braces 19, secured to said plates in any suitable manner, as shown.
