sn'rronrrnemamas Application filed January 16, 1928. serial llfl.'t?,233.

My invention relates to trolley poles and it has particular relation to ornamental trolley-Wire supports which may be utilized as standards for supporting lighting units and the lilcc.

In some thickly populated districts, trolley Wires are usually suspended by standards or poles placed along the curb, and, since these districts must be Well lighted, still another set of standards is utilized. for supporting the lighting units. This condition leads to a multiplicity of standards placed along the curb Which are unsightly and Which interfere With pedestrian trallic.

My invention is directed to an ornamental trolley pole Which may be also utilized tor supporting lighting units, thereby reducing the number of standards in any given d trict.

Therefore, an object of'my invention is to provide a combination lighting standard and trolley pole which will be ornamental and in Which the trolley-Wire-supporting means are concealed.

Another object of my invention is to provide a device of the above description, Which is simple and rugged in construction and which may be manufactured at a loW cost.

Stillv other objects of my invention Will become apparent from the following descrip tion of my device.

Referring to the drawing, in Which like figures indicate like parts,

Figure 1 is a View, partly in section and partly in elevation, of a combination trolley pole and lighting standard constructed according to my invent-ion;

Fig. 2 is a view, in cross section, taken along the line H-Il of Fig. 1.

Referring to the drawing, I prefer to util ize, as the trolley-Wire-supporting means, a hollow steel standard or pole 1 of any suitable type. A four-piece ornamental lighting standard 2 is placed over the supporting standard to enclose it, either before or after erection. The supporting standard may have its lower portion 3 buried in the ground, While the ornamental standard, Which is braced by the supporting standard and is not subjected to lateral strain, may rest upon the surface of the ground.

The supporting standard is provided, at its upperend, With a two-part collar at, which is fastened in place at the top of the stand ard by means of bolts 5. The collar is provided With threaded openin Other supporting members, such as a rod 8,

which is utilized for supporting overhead wiring extending parallel to the supporting arms oil. the standard, are provided to engage the bolts 5 which fasten the split collar to the supporting standard.

The ornamental standard may comprise four sections, including a base section 11, a column section 19., a supporting head 13 and a cap or finial. 14. Lighting units 15 may be fastened on the head at its upper portion 16 by means oil a fitter 17, or in any other W8llknown manner. The conductors for furnishing' electrical energy to the lamp of the lighting unit may be brought into the standard through openings 18.

The ornamental work of the head 13 is so designed that small circular figures 19 are provided at the central portion of the head. The material at the outer portion of these figures is made of decreased thickness, so that the circular figures may easily be removed by a blow from a hammer. Other socallcd knockout portions 20 are provided at the outer extremities of the supporting arms so that the rods 8 may be inserted therethrough.

In erecting the standard, as, for instance, for supporting trolley Wires, the supporting standard sunk in the ground and the base 11, column 12 and head 13 of the ornamental standard placed over the supporting-standard. The collar l is then bolted in place. Such knock-outs are removed as Will be necessary to i urnish the desired support for the trolley wire, and the supporting hook members 7 are inserted through the openings thus provided and threaded into the collar 3. one of the trolley-wire supports is desired at the end of the supporting arms of the head 13, the corresponding knock-out is removed, and the rod 8 inserted through the opening thus provided and fastened to a bolt 5 of the collar 4. The trolley-wire-supporting .vires or cables are then fastened to the hook members 7.

My trolley-Wire-supporting means are in- COHSPlCUOUS, especially at night, when the shadow cast by the litter 17 prevents the outer portion of the supporting rods from being clearly seen. The structure is ornamental and provides a very effective lighting standard, since the lighting units are placed at a considerable distance above the ground.

Although I have described only one specific embodiment of'my invention,modifieations may be made by those skliled in the art Without departing from the spirit and scope standard surrounding said supporting standard, and fastening means for supporting the overhead Wiring comprising a collar 'on the supporting standard, bolts engaging said collar, portions of the ornamental standard being made of relatively thin material in order to permit removal of the portions for insertion of parts of said supporting means.

2. A lighting standard comprising a supporting standard, an ornamental standard covering said supporting standard and having an ornamental lamp-supporting head, means comprising knock-outs in the column and lamp-supporting arm of the ornamental head for permitting attachment to the supporting standard of overhead wiresupporting means, the outline of the knockouts constituting a portion of the design figures on the ornamental head.

In testimony whereof, I have hereunto subscribed my name this 7 day of January, 1928.

RALPH W. ERSKINE.
