BASE ron LAMP-Postes AND TROLLEY-Winn roLEs.

`.Application led December 20,1927. Serial No. 241,415.

This invention relates' particularly to a base for imparting a Iinish to tubular iron poles such as are erected along streets `for the support ot' trolley wires, and for carrying street lamps, and for such joint use, but the base is applicable to poles and pipes for other uses, as for example, for flag-poles.

llhe object of this invention is to provide a base which will impart an ornamental character to the pole and which can be readily put in place after the pole has been erected. A further object, when the pole is used for the support of electric'lamps, is to provide protected space for the relays and switches by which the lamp is turned on and oi. AV further object, is to provide a base with surface ornamentation which will readily admit of molding. s g

In the accompanying sheet of drawings which forms a part of this description, j

Figure 1 is a vert-ical section through a pole-base according to this invention onv the line I-I of Figs. 2and 3, which is the plane of separation, the pole being indicated in Fig. 2 is an elevationot one of the parts of the `pole-base the other part and the pole being indicated in dotted line.

Fig. 3 is a horizontal section thrOugh the lower torus of the base on the line TIL-HI of Figs. 1 and 2. Y

Fig. 4 is an elevation of a connecting strap which forms an element of the upper torus.

Fig. 5 is an elevation of a connecting strap which forms an element of the lower torus.

The' pole-base comprises two like

parts

10, 10 each forming half of the base and meeting alongV a longitudinal plane throughL the axis, and the parts together forming a shell for enclosing the portion ot' a pole 1 1 which is adjacent to the ground. 1t is preferably configuration and includes near its upperpend a torus 12 and near its 'lower end a torus 13. The upper torus has

recesses

14, 14 and the lower torus has recesses 15, 15, both sets of recesses being adjacent to the meeting edges of the parts and the bottom of each being convex and substantially parallel to a continuation of the face of the torus. Fitting into the recesses in the upper torus and extending fromone part to the other are

straps

16, 16, and similarly tting into the recesses of the lower torus are

straps

17, 17. TheI straps are concave onv their inner sides and convex on thelr outer sides, and are bound to the recesses by screws l8, 18, and it the recesses so that the part-s are held against longitudinal displacement although only one screw holds each end ot a strap to the part. Y

The upper part of the base is circular and the lower part of the base is elliptical in preterence to being circular so that space is afforded on one side vfor a box 19 Jfor relays to control the lightingcirc-uits, and undue encroachment on the street is avoided. An opening is provided in the base opposite the box which isclosed by a cover 20.

The upper end of the base tsthe pole and the tips of lugs 21,21 engage the pole and hold the base concentric with the pole at a lower point. Y

The upper torus and also the lower torus both have strong relief ornamentation which does not interfere with the .drawing of the pattern from` the sand in molding because they are only carried around through an arc of 120 degrees instead of through 'a full halt circle so that undercuts in the ornamentation are avoided. The restriction of this are is by the recesses for which cores are set in molding. rlhe straps carryythe same designs and complete each torus.

vSince the pole is customarily set in concrete before the base is put in place, it would be necessary, if the base was in one piece, to hoist and lower it over the top of the pole. With this splitconstruction, the parts of the base are brought together around the pole from the ground or sidewalk. The wire connections to the relay box may be made either before or after the base is set in place. There is space for additional apparatus, it needed Von the side of the pole opposite the relay box'.

The invention is not limited to the provision of one opening and cover.

I claim,

1. An ornamental pole-base for surrounding a pole in longitudinally separable parts having a torus as an element of its design, the torus having recesses adjacent to the meeting edges of the parts, exterior straps forming segments of the torus for binding the parts together, and means for securing the ends of the straps in the recesses. Y 2. An ornamental pole-base for surrounding a pole in two parts longitudinally separable along a plane through its axishaving a torus as anelement of its design, the torus having recesses adjacent to the meeting edges of the arts, exterior straps forming segments o the torus for binding the parts toeo 'I .4. An ornamental pole base for surrounding a pole in longitudinally separable parts having a torus as an element of its design, the torus having recesses with vconvex bottoms adjacent to the meeting edges of the parts, exterior concave-convex strapsitting into theI recesses and forming segments of the torus for binding the parts together, and means for securing the ends of the straps in the recesses.
