Abstract

Abstract A bracket for the mounting of distribution transformer tanks to the tops of supports, such as utility poles is disclosed. The bracket is formed from a single stamped band of metal and includes a narrow vertically disposed front bracket surface just sufficiently wide to accommodate a conventional jump proof lip for attachment to a bracket or bolt holding the bracket to the support--such as a pole. Paired vertically disposed bracket sides diverge from the front surface to and toward the supported tank. These sides are bent at welding pad support legs. These legs are in parallel alignment, and extend until the tank sides. At the tank sides, the bracket at each side flares outwardly and ends to define a welding pad with discrete major surface areas tangent to the tank sides. When weld material is placed continuously around these firm tank attachment of the bracket occurs.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 226 words
In combination: a tank for supporting said distribution transformer; upper and lower brackets for the mounting said transformer tank to the tops of supports, such as utility poles; each said bracket formed from a single rectilinear band of metal, said band rectilinear about a major axis and having multiple folds normal to said major axis; said folds defining: a narrow vertically disposed front bracket surface between two central folds, said surface sufficiently wide to accommodate a conventional lip for attachment to a bracket or bolt; paired vertically disposed diverging bracket sides diverging from said front surface apart from one another to and toward said transformer tank and each ending at a weld pad leg fold; paired welding pad supporting legs beginning at said weld pad leg fold at the ends of said bracket sides remote from said front, said welding pad supporting legs bent in parallel alignment from until a point of contact with the tank sides; and, paired welding pads defining a major discrete surface area, one pad each attached to said welding pad supporting legs at pad support folds with said discrete surface area tangent to the exterior surface of said tank for permitting firm tank attachment upon circumferential placement of weld material completely around said welding pad; and, welding passes around each said welding pad for fastening said welding pad to said tank.
Claim 2
Dependent Claim 226 words
In combination: a tank for supporting said distribution transformer; upper and lower brackets for the mounting said transformer tank to the tops of supports, such as utility poles; each said bracket formed from a single rectilinear band of metal, said band rectilinear about a major axis and having multiple folds normal to said major axis; said folds defining: a narrow vertically disposed front bracket surface between two central folds, said surface sufficiently wide to accommodate a conventional lip for attachment to a bracket or bolt; paired vertically disposed diverging bracket sides diverging from said front surface apart from one another to and toward said transformer tank and each ending at a weld pad leg fold; paired welding pad supporting legs beginning at said weld pad leg fold at the ends of said bracket sides remote from said front, said welding pad supporting legs bent in parallel alignment from until a point of contact with the tank sides; and, paired welding pads defining a major discrete surface area, one pad each attached to said welding pad supporting legs at pad support folds with said discrete surface area tangent to the exterior surface of said tank for permitting firm tank attachment upon circumferential placement of weld material completely around said welding pad; and, welding passes around each said welding pad for fastening said welding pad to said tank.
Claim 3
Dependent Claim 26 words
The combination of claim 1 and further including: said diverging bracket sides diverge at and angle of about 30° with respect to said front bracket surface.
Claim 4
Dependent Claim 23 words
The combination of claim 1 and further including: a jump proof mounting at said front bracket surface of at least one said bracket.
Claim 5
Dependent Claim 25 words
The combination of claim 1 and further including: said welding pads diverging outwardly of said welding pad supporting legs at said distribution transformer tank surface.
