LAMP LEAD BRACKET FiledJan. 20, 1951 Patented Feb. 21, 1933 UNITED STATES PATENT oFFicE EDMUND W. BRADY, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE BRADY ELECTRIC & MANUFACTURING COMPANY, OF
NEW BRITAIN, CONNECTICUT LAMP LEAD BRACKET Application filed January 20, 1931.
My invention relates to a lamp lead bracket and more especially to a bracket provided with a split insulator, the parts of which may be readily separated to facilitate the introduction of a wire or wires therebetween.
The invention, generally speaking, relates to that type of insulator and insulator support shown and described in the patent to Herbert O. Rockwell, N o. 1,505,7 30, August 19, 1924, in which a generally hollow cylindrical insulator is shown divided along its axis into semi-cylindrical parts mounted between a pair of hinged straps which may be opened to permit the separation of the insulator parts during the insertion of the wire or wires, and then clamped together to secure and hold the wires in place.
Ordinarily, the parts of the insulator have been loosely mounted in the straps and readily become separated therefrom when the straps are opened. One of the objects of the present invention is to bring about a form of lamp lead bracket in which the parts of the insulator are attached to the straps so that the latter may be separated without any danger of the insulator parts separating from the bracket and dropping to the ground or otherwise inconveniencing a lineman.
A further object of the invention is to bring about a. form of lamp lead bracket in which brokeninsulator parts may be readily detached from the straps or other supporting members and replaced by new parts.
To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.
In the drawing:
Fig. 1 is a side elevational view of a lamp lead bracket according to my invention;
Fig. 2 is an end view of the same but on an enlarged scale;
Fig. 3 is a cross-sectional View taken along 2 line 3-3 of Fig. 2;
Fig. 4 is a view showing the bracket in position for insertion or removal of the insulator parts, and
Fig. 5 is a cross-sectional view along line 5.5 of Fig. 1.
Referring now to the drawing in which I Serial No. 509,939.
have illustrated my invention by showing a preferred embodiment of the same, the reference numeral 10 indicates in general the improved lamp lead bracket which includes a pair of straps 11 and 12, generally semicircular in shape and each having at one of its ends a loop designated herein by the reference numerals 13 and 14, a cylindrical opening 15 being formed in loops 13 and 14 in which a hinge pin 16 is mounted. At the opposite ends of straps 11 and 12 from loops 13 and 14 are arms 17 and 18, through which a bolt 19 passes, bolt 19 urging the straps 11 and 12 towards one another to clamp therebetween an insulator, generally designated by the reference numeral 20. Insulator 20 comprises two separable semi-cylindrical parts 21 and 22, grooved at 23 and 24 to form, when the parts are assembled together, an axially directed wire receiving opening 25.
In assembling the insulator parts 21 and 22 on the straps 11 and 12, the arms 17 and 18, as the case may be, are inserted between the rod 28 and the body of the respective insulator, as shown in the lefthand end of Fig. 4, whereupon the insulator may be moved along the strap into the position shown in the right-hand end of Fig. 4, and then rotated into final position on the strap. In case either or both of the insulator parts become broken they may be readily removed by reversing the assembling operation and new parts substituted therefor.
It will be readily understood from the above description of the invention that I have provided a lamp lead bracket or the like, in
which the insulator may be readily opened up to permit the introduction of a wire or wires without there being any danger of the insulator part-s becoming detached from their supports. Furthermore, in case either or both parts of the insulator become broken they may be readily replaced by a lineman without detaching the insulator support from its supporting structure.
- lVhile l have shown and described a preferred embodiment of my invention it will be understood that it is not to be limited to the details shown, but is capable of modification and variation within the spirit, of the invention and the scope of the appended claims.
