Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
A suspension bracket for use in supporting a power conductor insulator offset laterally from an upright pole, said bracket comprising three long rigid members converging upwardly toward one another at their outer ends, including a relatively shorter upper rigid tension member having its outer end rigidly sandwiched between the outer ends of a pair of relatively longer rigid struts having their lower ends diverging downwardly, means carried by said outer ends to support a high-tension insulator therefrom, a single arcuate base plate sized to embrace an upright pole in the area thereof between the downwardly diverging lower ends of said pair struts and provided with bifurcated lug means projecting outwardly away from the pole adjacent the lower ends of said pair of struts and lying generally parallel to one another, separate bolt means for securing said base plate and the end of said tension member to a pole in vertically spaced relation, and fastener means for rigidly securing the laterally diverging pole ends of each of said rigid struts to a respective one of said bifurcated lug means.
Claim 2
Dependent Claim
178 words
A suspension bracket for use in supporting a power conductor insulator offset laterally from an upright pole, said bracket comprising three long rigid members converging upwardly toward one another at their outer ends, including a relatively shorter upper rigid tension member having its outer end rigidly sandwiched between the outer ends of a pair of relatively longer rigid struts having their lower ends diverging downwardly, means carried by said outer ends to support a high-tension insulator therefrom, a single arcuate base plate sized to embrace an upright pole in the area thereof between the downwardly diverging lower ends of said pair struts and provided with bifurcated lug means projecting outwardly away from the pole adjacent the lower ends of said pair of struts and lying generally parallel to one another, separate bolt means for securing said base plate and the end of said tension member to a pole in vertically spaced relation, and fastener means for rigidly securing the laterally diverging pole ends of each of said rigid struts to a respective one of said bifurcated lug means.
Claim 3
Dependent Claim
87 words
A suspension bracket as defined in claim 1 characterized in that the surface of said arcuate base plate facing the pole has a radius slightly shorter than the radius of said pole and a hole through the central portion thereof for a mounting bolt securing said base plate to the pole, whereby the tightening of said bolt acts to press the outer ends of said arcuate base plate into the pole to resist any tendency for said base plate to pivot about the axis of said bolt.
Claim 4
Dependent Claim
62 words
A suspension bracket as defined in claim 1 characterized in that the fastener means securing the diverging pole ends of said pair of rigid struts to said bifurcated lug means are threaded and having a snug frictional fit with threaded bores through said rigid strut means and said bifurcated lug means to prevent arcing of leakage current and the generation radio interference.
Claim 5
Dependent Claim
29 words
A suspension bracket as defined in claim 1 characterized in that said rigid struts comprise elongated rods having flattened ends each provided with a transverse opening for a fastener.
Claim 6
Dependent Claim
24 words
A suspension bracket as defined in claim 2 characterized in that said arcuate base plate is ductile cast iron coated with corrosion resistant material.
