ATTORNEY Patented Oct. 22, 1935 UNITED STATES PATENT oEFicE 2,018,532 INSULATOR BRACKET Ralph B.. Pittman, Pine Bluff, Ark. Application February 25, 1935, Serial No. 8,034
5 Claims.
This invention relates to devices for supporting insulators on poles or other xtures, and has for its principal object the provision of a simple and inexpensive one-piece bracket on which may be mounted an insulator.
Other objects are: (a) to provide an insulator bracket over which a conductor may be strung without removing the insulator; (b) to provide an insulator bracket which may be securely mounted with one bolt or other suitable fastener; (c) to provide an insulator bracket which may be readily secured to either end of a bolt extending through a pole.
With these and other objects in view which Will appear from the description, my invention resides along the plane indicated by the line IV-IV in Fig. 3; and Fig. 5 is a side elevational view of two of the devices mounted on a wood pole in the service position.
Referring now in the base I0 is extending prongs adjacent the respective ends thereof, which are adapted to enter a wooden support when the device is installed in the service position. A slot I4 (Fig. 2) 'is provided in the base I0, extending longitudinally therein adjacent the upper and lower mediate the ends of the slot I4, is the substantially horizontal portion II, the latter providing a support for the insulator I9. 'I'he latter is fixed in position by the pin I2, which extends upwardly from and is integral with the outer portion of the horizontal member II. A hole II is provided through the pin I2 near the upper end thereof, through which a cotter pin or other suitable retainer may be passed.
An opening I3 (Fig. 3) is positioned through the horizontal member I I adjacent the base I0, which opening merges with the vertical slot I4. One purpose of this arrangement is to permit the passage of a bolt through the slot I4 below the member II, and subsequently passing the bolt head upwardly through the opening I3 so that the bolt may be inserted and positioned at the elevation o1' the insulator sulator.
In Fig. 5 two of the devices, indicated by the numeral I8, are shown attached to the pole 20 by means of the bolt 2| and the nut 22.
groove without removing the intion extending outwardly from said base to the other side and intermediate the ends of said slot, said horizontal portion 3. A bracket comprising a vertical base portion having a centrally positioned slot extending 1ongitudinally therethrough intermediate the ends thereof, an integral horizontal portion having a vertical opening merging with said slot extending outwardlyfrom said base portion intermediate the tegral horizontal portion extending outwardly from said base portion intermediate the ends thereof, and an integral pin extending upwardly into said insulator from said horizontal portion adjacent the outer end thereof, said vertical base portion having a slot extending above and below said horizontal portion intermediate the ends of said base portion, and an opening in said horizontal portion adjacent said base portion and merging with said slot whereby a fastening bolt may be positioned through said base at the elevation of said groove for preventing rotation of said bracket.
5. An insulator-bracket comprising a vertical base portion having a centrally7 positioned slotted opening extending therethrough intermediate the ends thereof, an integral substantially horizontal portion extending outwardly from said base portion, said horizontal portion being positioned substantially midway between the ends of said slotted opening and having a width substantially equal to that of said base portion, a vertical opening in said horizontal portion adjacent said base portion merging with said slotted opening, and an integral insulator pin extending upwardly normal to said horizontal portion adjacent the outer end thereof.
