Application filed September adapted for engagement upon poles of different diameters and acting as a support for an insulator, the construction of the bracket being such as to provide a rigid and adequately braced support capable of remaining in place and in good condition for an indefinite period. T

The object of the invention, more specifically stated, is to provide a pole bracket capable of-being formed from a single piece of sheet metal cut and bent to the desired shape so as to formarms embracingly engaging a pole and adapted to be secured thereto I and to form an integral brace bearingagainst and adapted to be positively secured to the pole.

Another object of the invention is the provision of a supporting bracket of this char acter in which the shape or formation of the brace element or portion may be varied depending upon the desired extent of the bracing action and depending upon the distance desired between the bolts employed for se curing the device in place.

A still further obiect of the invention is to provide a bracket of this character in which the pole engaging or embracing arms may be arranged to diverge to a greater or a less extent depending upon the size of the pole to which the device is attached or upon 7 which it is to be mounted.

To the attainment of the foregoing and other objects and advantages such as simplicity and cheapness in manufacture, the invention consists in the construction and ar rangement to be hereinafter more fully de scribed and claimed, and illustratedin the accompanying drawings wherein:

Figure 1 is a plan view of the bracket in applied position,

Figure 2 is a side elevation thereof,

Figure 3 is a detail view of the blank from which the bracket may be formed, and

Figure 4 is a side elevation showing a slight modification.

Referring to the drawings indetail, the numeral 1 designates a pole of an ordinary and well known type upon which is mounted the bracket, designated generally by the numeral 2. In the present instance the bracket 22, 1-925; Seria1 No. 57,9 73.-

is represented as located'nea'r thetop of the pole though'itfl-should be understood that-- may be mountedat any desired height.

The bracket 2 is shown as includinga horizontall-y disposed platform Or table portion 3 having downwardly extending side portions there is no limitation in, this respect as it 4 terminating in arms 5 which diverge and which are preferably curved so as toconform to a greater or less extent to the curvature of the pole. Extending downwardly from that portion of the table or platform" nearest the pole is 'a'brace arm 6 'which'may be at right angles to the table portion as shown in-F igure 2 or which may have its upper portion ,in clined with respect to the table portion, as shown-at 6 in Figure 4. In either event it is intended that the brace arm 6 lie flat against the side of the pole. For effecting securing use may be made of bolts 7 and 8 extending transversely through the pole, the former passing through arms 5 and the latter through the brace arm 6" or 6 as the case may be. Naturally, nuts 9 and 10 are provided'for the respective bolts 7 and 8 for securely hold- 'ing the bracket in place. -While I have repbe mounted. As such supportingv elements and insulators form no part of the present inventionthey are not shown though they are mentioned as bringing out the utility of the bracket.

Obviously, the arms 5 may be of any suit-- less extent depending upon the diameter of the pole to which the bracket is attached and it is likewise true that the brace arm 6 or 6 able length and may diverge to a greater 0I- i may be of any preferred length, it being clear that by providing a longer brace arm the bolt 8 may be removed a greater distance from the bolt 7 to avoid any possible weakening of the pole.

For convenience'and simplicity in manufacture, the bracket may be formed from a single blank shown at 12 in Figure 3, this blank being out upon spaced longitudinal lines 13 to define the arm portions 5 and the brace .tions A.

portion 6, the material outwardly of the cuts 1 3 being bent overat right angles upon the lines 14 to define the side portions 4L which make the body of the bracket channel shaped or substantially inverted u-shaped in cross I section or end elevation, this shape being dcsirable in thatthe side portions 4 will then act as stiffeners to give the bracket rigidity. The brace'portion 6 is bent downwardly upon the line 15 to extend either at right angles to the table portion 2, as in Figure 2, or at an angle, as in Figure 4:. The lines 16 in Figure 3'indicate the points at which the arms 5 begin to diverge with respect to the side por- VYhile this particular method of construction from a single-blank ishighly' desirable on accountof simplicity and the fewness of ;operations involved it is quite possible that the bracket might be formed in some other manner, it being conceivable that it could be constructed as a casting if such should be found. desirable for any reason. It is equally apparent that the various anglesand .lines ofbending may be varied ifpreferred and ,I reserve the right to make all such a horizontally disposed platform portion having depending side flanges arranged at right angles thereto and terminating in divergcnt arms ,adapted to be embracingly engaged upon a pole in contact with diametrically opposite pointsthereof, said platform portion extending to the pole and having formed integrally thereon a depending brace arm extending at right angles to the platform portion and lying flatly against the side of the polethroughout its length, a single securing member passing through the pole and said divergent arms, and a securing'member passing through said brace arm and the pole.

In testimony whereof I aflix my signature.
