Definitions

  • This invention relates to supports for insulators of current transmission lines and has special reference to supports of that type used in that character of installation where it is customary to provide a wooden crossarm on a pole and to mount two insulators upon the end portions of such cross-arm, and an additional insulator on the pole itself near the top thereof.
  • Tt is well known in the art that where use is made of a wooden cross-arm the bolts for holding the pins which support the insulators on the cross-arms are necessarily of considerable length owing to the thickness of the wooden cross-arm, whereas the bolt provided for securing the insulator supporting pin upon the metal bracket commonly used at the top of the pole is quite short.
  • the result is that the manufacturer must carry and the customer use two types of pins or pins having bolts of different lengths, thus at least prac tically doubling the amount of stock to be kept on hand, with the attendant inevitable disadvantages when handling different styles or sizes of articles.
  • T have designed a pole top bracket of such con struction as to take the same length of bolt as is provided for the pins mounted on the crossarm, thereby making it necessary to make and use only one size instead of two, resulting in a decrease in the cost of production and increase in the ease of installation.
  • An important object is to provide a pole top bracket which does not in any way require the use of a special bolt or pin, exactly the same ones used on the wooden crossearm being engageable upon this bracket.
  • a further object of the invention is t0I provide a bracket of this character which is preferably formed from a single piece of material capable of being stamped to shape and which will consequently be extremely cheap and easy to manufacture as well as easy to apply in addition to being efficient and durable in service.
  • the invention preferably consists in the details of construe* tion and the arrangement and combination of Serial No. 262,205.
  • Figure 1 is an elevation of a supporting pole and wooden cross-arm thereon and illustrating a pair .of insulators mounted upon the cross-arm and a third insulator mounted upon the bracket constituting the subject matter of the invention, and
  • Figure 2 is a perspective view of the bracket alone.
  • the numeral 1() designates a pole of ordinary type on which is mounted a wooden cross-arm 11 preferably strengthened'by the inclined braces 12 in addition to being held by the bolt 13.
  • the cross-arm is located at a position spaced somewhat downwardly from the top of the pole so that the latter will project upwardly so as to be capable of supporting an insulator in a higher position. This is an extremely common type of installa tion.
  • This bracket 18 includes a main elongated plate-likebody portion 19 which has its upper end bent or otherwise formed to extend at right angles for providlator pin at the top of the pole. Intermediate its ends the plate portion 19 is provided with a laterally extending lug 21 here disclosed as struck-out from the plate portion,
  • a shelf 20 serving as a seat for the insu! lll the latter being initially out along parallel longitudinal lines 22 and a transverse line 23 so that the material lying between these lines may be forced out to extend right angularly as shown.
  • the shelf 20 and lug 21 are formed with alining holes 24 and 25, respectively, which may be drilled or otherwise formed, and which are for the passage of the pin 16.
  • the intention is that the distance between the top surface of the shelf 20 and the bottom surface of the lug 21 be substantially the same as the thickness or height of the cross-arm 11 so that the same length of bolt will be used for mounting the pin either upon the bracket or upon the cross-arm.
  • I preferably provide a sleeve 26 surrounding the bolt and extending between the shelf 20 and the lug 21 for the purpose of preventing drawing them together when the nut 17 is tightened.
  • the sleeve consists simply of a length of ordinary pipe.
  • bracket have its plate or attaching portion 19 flat, as shown, or concavo-conveX in cross section to conform more or less to the curvature of the pole, as this is a mere detail of design.
  • the plate portion is formed with any suitable number ⁇ of holes 27 for the passage of bolts or lag screws 2S whereby the bracket may be mounted upon the pole.
  • a pole top bracket for supporting an insulator carried by a pin from which depends a bolt equipped with a nut, said bracket comprising a metallic member having its upper end formed with a lateral extension constituting a shelf and having its intermediate
