SHAFT STRUCTURE.

Application filed June 11, 1926. Serial No. 115,230.

This invention relates to sheet metal columns and more particularly to a column of this character'adapted especially for use in a shaft construction comprising a pole of rolled steel or the like, for supporting trolley wires, lighting fixtures and similar devices, the steel pole beinggfor the purpose of ornamentation, surrounded by a shaft comprising a fluted sheet metal column having an ornamental base and capitol.

Where such steel poles are used for supporting trolley wires and similar structures moved from the structure to permit access to or inspection of the inner pole.

The above and other objects may be accomplished by providing a shaft structure umn is removed, to permit inspection of the lower portion of the steel pole, an ornamental capitol for said sheet metal column being suspended from the upper end of the steel pole and telescoping over the sheet metal column, permitting the sheet metal column to be removed without aflecting the support of the capitol, and compensating for differences in the heights of the poles, when set up.

An embodiment of the invention is illustrated in the accompanying drawing, in

which through the improved shaft structure, and

Fig. 2, a section of the fluted column only on the line 22, Fig. 1.

Similar numerals of reference indicate corresponding parts throughout the draw- The post 1 may be of tubular cross section, mounted upon a suitable base, such as shown at 2, which is anchored in the usual cement or concrete'foundation 3. This post may support a trolley wire, or the like, by means of the usual guy wire or similar means, and may support any desirable lightmg fixture, as shown generally at 4, at its upper end. 1

For the purpose of ornamentation this supporting pole is surrounded by a sheet metal column 5 which is preferably a tapered fluted column as illustrated. This sheet metal column is, supported upon a base comprising the cast pedestal portion 6 and one or more superposed,- annular base members 7.

The capitol 8 is suspended entirely from the upper end of the supporting pole 1, being'preferably supported by means of the tie bars 9 which extend through the annular flange 10, at the upper end of the thimble 11 which is inserted into the top of the pole 1.

The upper end of the fluted sheet metal column 5 is telescoped into the lower 0 en end of the capitolcompensating for di erences in the height of the pole. Thus it will be seen that the capitol is supported entirely upon the pole 1 and is independent of the ornamental sheet metal, permitting the column to be removed, to inspect the pole 1, without disturbing the capitol.

For the purpose of permitting acces to the upper portion of the pole, the tie are 9 may be loosened and the capitol lowered to any desired position upon the pole and held by means of the set screws 12. 4

In order to provide for quickly and readily removing the sheet metal column 5, to inspect the pole 1, this sheet metal column is formed of two similar half-round sections,

each of which has a strip 13 connected to In assembling the sheet metal column, around the pole, these sheet metal sections are placed in position, upon the base, and quickly connected, by means of the screws 15, and since the strips 13 are upon the inside of the sheet metal column, the appear ance of the column from the exterior is not in anyway detracted from.

To inspect the pole 1 it is only necessary to remove the screws 15 and detach the fluted sheet metal sections permitting access to thedetachably connected at their longitudinal edges.

2. A shaft structure mcludmg a supportlng pole and an ornamental column surrounding said pole and formed of sections hating overlapping flanges at their l0ngitudinal edges and means for detachably connecting each flange to the overlapping adreoonee I joining edge portion of the adjacent section.

3. A shaft structure including a supporting pole, an ornamental column surrounding said pole and a capitol suspended from the upper end of the pole.

4. A shaft structure including a supporting pole, an ornamental column surrounding said pole and formed of sections detachably connected at their longitudinal edges and a capitol suspended from the upper end of the pole.

5. A shaft structure including a supporting pole, an ornamental column surrounding and pole and formed of sections detachably connected at their longitudinal edges and a base for the ornamental column comprising a plurality of superposed sections surrounding the pole.

6. A shaft structure including a supporting pole, an ornamental column surrounding said pole, a capitol suspended from the upper end of the pole and a base for the ornamental column comprising a plurality of superposed sections surrounding the pole.

In testimony that I claim the above, I
