TELEGRAPH-"POLE.

SPECIFICATION forming part of Letters Patent Nol '752,259, dated February 16, 1904. Application filed June 15,1303. Serial No. 151,568. (No model.)

. To all whmn it may concern:

Be it known that I, J OHN H. PURDY, a citizen of the United States, residing at New'London, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in ".lelegraph-Poles, Anchors for Telegraph, Telcphone, and Electric-Light Poles, lenccPosts, &c., of which the following is a specification.

ware, they are strengthened and made more serviceable by having embedded thereinpstout wires or rods to continue the post or pole in service in case of breakage until repairs may be conveniently made.

For a" full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached. 1 While the essential and characteristic featu res of the invention are susceptible of modification, still the preferred embodiment or the invention is illustrated in the accompanying drawings, in which- Figure l is a perspective view 0 l a telegraphpole embodying the invention. Fig. 2' is a cross-section oi the pole, showing wooden splice-bars connecting the sections. Big. 3 is a. section similar to Fig. 2, showing metal splice-bars of angular forn'ihtion. Fig. 4 isa perspective view of a fence-post embodying the invention.

Correspomling and like parts are referred to in thcl'ollowing description and indicated .in all the views of thedrnwings by the same reference characters.

The pole or like supportmay comprise any number of sections, according to it length and diameter, sons to admit of the parts being conveniently handled. In cross section the pole or support is of cruciform or winged formation, this construction having'been found to give the best results both with respect to strength and lightness. To stiffen, strengthen, and increase the durability of the pole, stout wires or rods 1 are embedded therein, the

same being distributed, so that each wing of the pole is supplied with a stay wire or rod.

Notches 2 are formed in one or more of the wings-and constitute steps to facilitate climbing of the pole,

In the preferable construetion the notches or steps 2 are formed in oppositely-disposed wings and are alternately arranged. The wings also provide convenient handholds' The sections comprising the pole when abutted are connected by splice-bars, which, may be of wood or metal, the same being arranged in the angle formed between adjacent wings, andif needs be may extend the entire length of post or pole in sections. When the splice-bars are of wood they are approximately oftriangular form in cross-section, as shown most clearlyin Fig. 2. hen the splice-oars are formed of metal, they comprise singularlydisposed wings, as indicated most clearly in Fig. 3, said wings conforming tothe angular space formed between adjacent wings. The wooden splice-bars are indicated at 3 and the metal splice-bars at 3. The ties 4 for connecting the splice-bars to one another and to the sections of the pole or support pass diagonally through the letter, thereby serving to draw the splicebars close into the angles formed between the wings. This manner of connecting the splice-bars enables the fastening to be efiected by two sets cities, as will be readily "comprehended: The tie's 4 maybe bolts, clips, or any type of fastener commonly employed for connecting-parts in the erection of structures of any kind. The base or. ground sections may be used as anchors for windmilltowers, bases for wood, metal, or any kind of telegraph, telephone, or electric-light poles and may be made of any length, size, and

shape, as occasion may require. InF1g.

base or ground section is utilized as a :t'oundation for a fence-post 5, an upper portion of one of the wings being cut away to provide a fiat side, against which the board 5 is secured:

by suitabie fastening means. The lower end of the board is downward]; and outwardly beveled and the upper end of the wing cut away to form a step or support for board. This construction admits of the shedding of Water and obviates the quick wearing away of the lower end of the board, which would result if its lower end were square and stepped upon a square shoulder.-

Having thus described theinvention, whatis claimed as new is 1. A pole or like support composed of sections, each section comprising corresponding wings, splice-bars fitted in the angles formed between adjacent wings, and ties connecting diagonally-disposed splice-bars to each other and to the sections of the pole, substantially as set forth.

2. A pole or like support composed of sections, each section comprising corresponding Wings, splice-bars fitted in'the angles formed between adjacent wings, each comprising corresponding'.wings conforming to and fitting snugly against the wings of the pole-sections,

and ties passed through the angles formed between the wings of the splice-bars and conmeeting diagonally-disposed splice-bars to each piece of other and to the pole-sections, substantially as set forth.

3. A pole or post forelectric light, telegraph or telephone wire support to be made of earthenware, glass, concrete, cement, metal or any durable substance, composed of sections, each section comprising corresponding wings or flanges, and ties connecting diagonally-disposed spliee-bars to each other and also socurely connecting the sections forming them into a pole or post for the purposes before mentioned, its shape being cruciform, as set forth, with notches in its sides to be used as steps going to and from wire and cross-arms, substantially as set forth.

4. A post or pole support coniposedof sections snugly fitted together and secured by tics passed through the angles formed between the wings, and splice-bars firmly connecting the sections forming the post or pole,substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.
