PiLCIFiCATICiNiorming part of Letters Patent No. 650,791, dated 29, 1960. Application filed August 10,1899. Serial No. 726,815. (No model.)

T at whom it mayponcerre:

Be it known that I, JOHN M. HANSEN, a citizen of the United States, residing at Bellevue, in the county of Allegheny and State of Pennsylvania,have invented a certain new and useful Improvement in Pressed-Steel Poles, of which the following is a full, clear, and exact description.

This invention relates to metallic poles,and

IO more especially to poles for trolley-railway lines.

The invention consists of a pole made from sheet or plate steel pressed to shape and in sections, which are riveted together, and provided at the ground end with oppositely-arranged anchoring devices, substantially as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawings,illustrating my invention, in the several figures of which like parts are similarly designated, Figure l is a side elevation with the middle portion broken out, thus to accommodate a view on as large a scale as possible to the drawing-sight,

and the tip in partial section. Fig. 2 is a front elevation similarly broken out. Fig. 3 is a cross-section, on a larger scale, which might be taken anywhere between the groundlevel and the tip of the pole. Fig. 4 is a cross 0 section, also on a larger scale, taken on the ground-level. Fig. 5 is a perspective View of half of one of the anchors.

While I do not limit my invention to the shape of the pole, stillI prefer to make itv 3 5 with an approximately-circular cross-section and will describe such construction in detail.

The pole is composed of semicylindrical sections or a, each being made with lateral plane flanges b b on opposite sides, and when these sections are assembled, as represented in the drawings, and are united by rivets 0 passed through their flanges they form a tubular body. I prefer to make this tubular body tapering, with its largest diameter at the bot- 5 tom. The top of the pole may be provided with any suitable cap d,- secured thereto in any suitable manner, and, if desired, having a flange e, which is inserted in the tube. The upper end of the tube may be provided with cross-arms in any usual way or may be otherwise adapted to receive wires or other fixtur'es.

In order to anchor the pole firmly in the earth and stay it againstlateral displacement,

I provide the lower end with oppositely-arranged anchors f 9, one of said anchors being arranged at one side near the ground-level and the other being arranged at the opposite side at or near the bottom of the pole. Each of these anchors is composed of two plates h, such as shown in detail in Fig. 5, and each plate comprises a flange h, a web k which is reinforced by the pressed-up buttress h and the flange h, parallel to flange h, and,

as shown in Fig. 4-, to constitute an anchor two of the plates shown in Fig. 5 are arranged on opposite sides of the flanges b b of the pole and riveted thereto by rivets i. It will be observed that the flanges k are curved or shaped to correspond to the perimeter of the pole, so that when the plates are assembled,

as in Fig. 4, they not only fit snugly to the flanges, but*also against the tubular portion of the pole. The opposite arrangement of the anchors affords the bestresistance to the 7 5 strains that are putupon the pole and serves to minimize the deflection of the pole incident, to such strains.

All the parts hereinabove described as entering into the construction of my pole are 86 formed of sheet-steel or steel plate pressed to shape, and thus a very stiff, strong, and durable pole may be produced very economically.

As already indicated, I do not limit my in-n vention to the shape of the pole or of its 'sections, and I Wish to be understood, further, that I do not limit my invention to the number of sections of which my said pole may be constituted.

What I claim is go 1. A pole, composed of semicylindrical flanged sections, riveted together, and pro vided with oppositely-arranged anchors, each anchor comprising a pair of plates h having flanges bentto conform to the body of the pole, outside flanges and webs connecting said flanges, said plates being united to the flanges of the pole and to each other by their webs, substantailly as described.

2. A pole, composed of flanged sections, rivroo of the pole, substantially as described.

eted together and provided with oppositelyarranged anchors, each anchor comprising a pair of plates h having outside flanges 71., Webs 7L and inside flanges 7r, said plates secured to the flanges of the sections and to each other by their webs, the anchors being arranged at diiferent altitudes 011 the ground end or base one just below the ground-level and the other at the bottom of the pole, substantially as described.

4. A metallic trolley-pole,composed of semi- 2o cylindrical flanged sections, riveted together, and anchors consisting of plates it having outside flanges, buttressed webs and inside flanges, and riveted in pairs to the flanges of the pole, substantially as described.

In testimony whereof I have hereunto set my hand this 5th day of August, A. D. 1899.

JOHN M. HANSEN.
