Application inea May 21,

This invention relates to gain xtures for poles and has for its object to secure the ixture in a stable manner to the pole without the use of any bolts extending entirely through the pole and without breaking down the fiber of the pole, the bo'dyportion of the fixture being so formed as to provide a ventilating air spaceV between the pole and Vsaid body, as well as an air space extending en-` tirely through said body, so that the-Cross-v arm supported by the latter will be exposed to the air throughout the major portion of its rear face. Y

A further object is to` secure the cross-arm to the fixture without the use of any bolts extending into or through the pole.

In the accompanying drawing e Figure 1 is an elevation showing Vthe ixture secured to the pole and with thecrossarm bolted to the fixture.

Figure 2 Figure 1. Y

Figure 3 is a plan view, of the structure shown at Figure 1, and Y v Figure eis a detail rear elevation of the' xture itself. j f

Similar numerals of reference denote like parts in the several gures ofthe drawing.

Heretofo-re meta-l gain lixtures have been secured to a pole, but they have been equipped with chisel shaped flanges that have been driven into the pole by the process of securing the iixture thereto thus breaking down the ber of the pole therebyreadily admitting moisture and eventually causing the pole to rot so as to bring about the loosening of the fixture.

Also the cross-arm has been secured by means of a bolt that extended entirely through the pole, and as this bolt was frequently driven through a comparatively small opening into the pole so. as to secure Vis a section at the line 2-2 of tightness7 the yconsequence has beenthat the pole wouldV start to split which splitting would be increased as the strain' brought to bear on the fixture during heavy storms would cause swaying of wires possibly'heavily laden 1929. seal Noq 364,858. p

is secured t-o thelixture itself and the pole is not penetrated. I

, l is the pole and 2 the main body portion of the fixture which has a plurality ot' perforations 3 extending therethrough and taking up the greater; area of this body portion.

lare spacedelongated ledges which ex- 'tend from the front of the iixture, 5 is a leg extending from the body portion 2 at themiddle topv portion thereof and 6 are spaced legs extending from the lower portion of said body. Y

7 is a lag screw driven into lthe pole through the leg 5 and 8 are lag screws likewise driven into the pole through the legs 6` Athese lag screws'aiordingmeans for securing the xture tothe pole at three triangularly. disposed points, thus insuring stability. Y Y f In the rear face of the body portion 2 is a countersunk rectangular recess 9,'for the purpose presently to be explained. i

10 is a cross-arm positioned between the ledges and secured to the fixture by means of a bolt 11 whose head 12 is housed within the recess 9, a nut 13 being driven on the front end of the bolt against a washer 14 placed against the front face of the cross-arm.

' The rearl face of the body portion 2 is spaced from the pole l as seen at15, so that it will be clear that the only point of Contact the medium of the legs '5 and 6, while the body portion itself, owing to the plurality of openings 3, aifords free access of air to the rear face of the cross-arm 10 thus preventing the sweating and consequently rotting of the latter due to thepresence of moisf ture.

There is no breaking down of the fiber of the pole, since the holes for the lag screws are clean cut, and therefore the likelihood of any rottingl of the pole due to the securement of the .iixture is reduced to a minimum.

It will, of course, be obvious that the position vor vthe fixture on the pole may be reversed, and in this instance Vthe legs 6 would bezat the top ofthe fixture while the leg would be at the bottom. What is claimed iszv The hereindescribed gain fixture for poles Y comprising a main body portion having an angular recess at the center of its rear face and a plurality of air openings extending through its back from front to rear, a single leg extending from the top of said portion and midway thereof, a pair of legs extending from the lower ends of said portion, said legs having feet that are concaved to closely oontact the pole, horizontal spaced ledges formed at the front of said body portion and adapted to house a cross-arm, lag screws driven through said legs into the pole, said body portion being spaced from the pole whereby an air space is provided between said pole and portion, a eross-arm positioned between said ledges, a bolt having an angular head that is housed within said recess, said bolt extending through said cross-arm, and a nut driven on the end of said bolt against said cross-arm.

In testimony whereof I alix my signature hereto.

ROLLAND G. WILLIAMS.
