Serial" m5. 345,541.

This, invention relates to pole mounts but more particularly has reference to the mounting of steel polesknown as H-poles, that is to say, poles whose cross-section is shaped like 6 the letter H.

The object of the invention is to securely mount these poles in such manner that they will have no contact with the mounting itself but will be separated therefrom by an unobmounted in accordance the upper portion of the pole being broken.

structed air space, while atthe same time,

the poles may be readily removed and other similar poles substituted therefor with no change in the mounting or in the securing fixtures. 7 i I In the accompanying drawings, which illustrate a preferred form of the invention Figure 1 is an elevation showing a pole with the invention,

away.

Figure 3 is a view similar to Figure ,1, but taken at right angles thereto, and

Figure 4 is a section at the line 4.-4 of Figure 3.

Similar numerals of reference are used to denote like parts in the several figures of the drawing. I n

The mounting proper is a concrete block 1 the main body of whichis sunken in the ground, and embedded within this block and firmly anchored therein are upright stanchions 2, preferably four in number, which 7 project a suitable distance above the block and are screw threaded at their ends. I

The mounting fixtures are two in number and are exactly alike and are generally denoted by the numeral 3, and each fixture has a broad base 4 that rests on the block,

1 and upright members" 5 that embrace the flat surfaces 6 of th pole 7 on opposite sidesof the latter;

8 are seats that extend inwardly from the bases 4 on which seats the pole rests, so that vthe bottom of the latter is spaced from theconcrete block, as shown at Figures 1 and 4.

Reenforcing ribs 9 and '10 extend from the ends and sides of the base 4;.at right angles a to each other and merge intothe upper ends Figure2 is a section at the line 2'-2 of Figure 1.

of the upright members 5, and the bases are cored out as seen at 11 to lighten the castings and facilitate'the piercing of the basesto accommodate the stanchions 2 without detracting from the essential strength of the fixtures.

All the poles are standard as to dimensions and if poles of different'dimensions are used, it will, of'course, be necessary to employ fixtures whose dimensions difier accordingly.

The fixtures have channelsfjlfZ that extend vertically from the seats 8 through the length of the inner faces of the upright members 5,

and'the width of these-channels is such that the faces 6 of the poles, when the latter are properly assembled with regard to the fixtures, are enclosed within these channels, as shown at Figure 2. V

It is immaterial whether the fixtures are first, positioned on the block 1 with the stanchions 2 projecting through the bases, and the pole lowered within the channels 12 and rested on the seats 8, or whether the pole is first lowered so thatit rests on the block 1 and then slightly raised so that the fixtures can be applied to the pole and finally lowered until the pole rests on said seats. v 7

After the pole and fixtures have been prop erly positioned with respect to each other,

bolts 13 are passed through the fixtures and the faces 6 of the poles and tightened by nuts 14 driven on the ends of the bolts, and nuts 15 are then driven on the ends of the stanchions to firmly clamp the fixtures to the block 1.

r The embracing of the poleby the fixtures takes the strain from the bolts 13 as the pole sways, owing to storms and other causes, and contributes greatly to the solidarity of'the structure as a whole and the unity of the latter in resisting strains in all'directions.

The spacing of the bottom of the pole from the block'l prevents the grinding of the pole into the concrete, and the disintegration of the bottom of the pole owing to the erosive action of moisture when the pole contacts a foreign element. Again, the air space heneath the pole gives a free circulation of air and a ready passage for water and the pole is not likely to become rusted.

Having thus described my invention What I claim as new and desire to secure by Letters Patent is 2-- A mounting for a steel pole H-shaped in cross-section, comprising a concrete block embedded in the ground, stanchions anchored within said block and extending above the latter, separate fixtures having bases seated on said.-block withisaid stanchions extending throughand-above said bases, the latter having seats that extend inwardly, upright members rising from said bases and having channels that extend integrally from said seats vertically throughout the length of said Inembers, whereby the pole may be assembled between saidifixtu'res with its 'fiat faces enclosed Within said channels and its lower end resting on saidseats, tivo vertically disposed se-' ries of'bolt's passed through said' flatffaces and upright members, each of said'seri'esex tending throughout the height of said? uprightmembers and located; respectively at oppositeedg'es' of'saidfa'ces, nuts driven on said bolts whereby said'faces'are clampedto said members'on 'opposite'sides of the crossbar of the H shapedpole, and nutsdriven on the ends ofsaid' stanchions whereby the fixtures are firmly secured to said;block.

In testimony whereof I aflix' my signature hereto,

HOLLAND G. WILLIAMS;
