Abstract
Abstract A motor mounting bracket which includes a plurality of elongated longitudinal wires or rods for extension along the sides of a cylindrical motor housing, and a plurality of annular wires or rods encircling the elongated first mentioned wires and welded or attached thereto for retaining the first mentioned wires against the side of the motor housing. The annular wires are preformed to accommodate the longitudinal elongated first mentioned wires while retaining at least a portion of the total length of the annular wires or rods in position to contact the cylindrical housing of the motor. Mounting rings or loops are formed at one or both ends of a plurality of the elongated longitudinally extending first mentioned wires to facilitate the mounting of a motor held in the mounting holder and bracket of the invention against another structure, such as the housing of a squirrel cage blower driven by the motor. The annular wires or rods carry, at a pair of opposed ends thereof, brackets having aligned apertures therethrough to permit a tensioning bolt to be passed through the apertures to tension the annular wires.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
90 words
A motor mounting bracket comprising: a plurality of annular bands disposed in substantially parallel planes; a plurality of spaced, elongated rods extending substantially normal to said annular bands and each secured intermediate its length to each of said bands at points on the inside of the respective annular band whereby said rods are enclosed within said bands; means at one of the ends of each of said rods for securing said bracket to a supporting structure; and means for tensioning and constricting said bands to reduce the effective diameter thereof.
Claim 2
Dependent Claim
90 words
A motor mounting bracket comprising: a plurality of annular bands disposed in substantially parallel planes; a plurality of spaced, elongated rods extending substantially normal to said annular bands and each secured intermediate its length to each of said bands at points on the inside of the respective annular band whereby said rods are enclosed within said bands; means at one of the ends of each of said rods for securing said bracket to a supporting structure; and means for tensioning and constricting said bands to reduce the effective diameter thereof.
Claim 3
Dependent Claim
50 words
A motor mounting bracket as defined in claim 1 wherein said means for securing said brackets to a supporting structure comprises a rigid ring disposed at said one end of each of said rods, and lying in a plane extending substantially parallel to the planes in which said bands lie.
Claim 4
Dependent Claim
33 words
A motor mounting bracket as defined in claim 1 wherein said tensioning means comprises: a pair of tensioning plates secured to said bands; and means for drawing said tensioning plates toward each other.
Claim 5
Dependent Claim
69 words
A motor mounting bracket as defined in claim 1 wherein each of said elongated rods is further characterized in having: a central portion extending between points of securement of the respective rod to said annular bands; and end portions connected to said central portion and angled with respect thereto at an acute angle of less than 45*, and angled away from the interior area encompassed within said annular bands.
Claim 6
Dependent Claim
72 words
A motor mounting bracket as defined in claim 1 wherein said means for securing said brackets to a supporting structure comprises: a foot portion at said one end of each of said rods and extending in a plane which is substantially parallel to the planes occupied by said bands; and a bolt-receiving loop formed on each of said foot portions, said foot portions and loops all lying in substantially the same plane.
Claim 7
Dependent Claim
84 words
A motor mounting bracket as defined in claim 1 wherein each of said bands is angled through an obtuse angle at its point of securement to each of said rods, with the respective rods being disposed at the vertex of the angle, and the respective band extending from such vertex substantially tangentially with respect to a circle of the least diameter sufficient for the circle to touch each of said rods on the opposite side thereof from its point of securement to said bands.
Claim 8
Dependent Claim
139 words
A motor mounting bracket comprising: a plurality of elongated rods spaced frOm each other on substantially equidistant spacings on the periphery of an imaginary circle lying in a plane extending substantially normal to the longitudinal axes of said rods; a plurality of spaced bands encircling said rods and each defining obtuse angles equal in number to the number of said rods, each of said rods being positioned in one of said obtuse angles of each of said bands at the vertex of said angle and secured to the respective band at said vertex; means for constricting and tightening said bands about said rods to cause said rods to be moved toward the center of said imaginary circle; and means for securing ends of the several rods to a supporting structure for supporting said bracket and a motor mounted therein.
Claim 9
Dependent Claim
139 words
A motor mounting bracket comprising: a plurality of elongated rods spaced frOm each other on substantially equidistant spacings on the periphery of an imaginary circle lying in a plane extending substantially normal to the longitudinal axes of said rods; a plurality of spaced bands encircling said rods and each defining obtuse angles equal in number to the number of said rods, each of said rods being positioned in one of said obtuse angles of each of said bands at the vertex of said angle and secured to the respective band at said vertex; means for constricting and tightening said bands about said rods to cause said rods to be moved toward the center of said imaginary circle; and means for securing ends of the several rods to a supporting structure for supporting said bracket and a motor mounted therein.
Claim 10
Dependent Claim
69 words
A motor mounting bracket as defined in claim 7 wherein each of said bands is of fixed length and has a pair of ends at the opposite ends of the respective band; and said means for tensioning said bands comprises: a plate carried at each of the ends of each of said bands; and means for drawing said plates toward each other to thereby constrict each of said bands.
Claim 11
Dependent Claim
128 words
In combination: a motor having a cylindrical housing and having an output shaft extending substantially coaxially in said housing and projecting from one end of the housing: a bracket surrounding and enclosing said motor, said bracket comprising: a plurality of rods spaced substantially equidistally from each other around said motor housing, and each having a central portion contacting said housing and extending substantially parallel to the axis of said cylindrical housing; and a plurality of spaced bands encircling said rods to the outer side thereof and tensioned to force said rods into contact with said housing along a central portion of each of said rods; and means for securing said rods to a supporting structure whereby said rods, bands and motor can be cantilevered from said supporting structure.
Claim 12
Dependent Claim
128 words
In combination: a motor having a cylindrical housing and having an output shaft extending substantially coaxially in said housing and projecting from one end of the housing: a bracket surrounding and enclosing said motor, said bracket comprising: a plurality of rods spaced substantially equidistally from each other around said motor housing, and each having a central portion contacting said housing and extending substantially parallel to the axis of said cylindrical housing; and a plurality of spaced bands encircling said rods to the outer side thereof and tensioned to force said rods into contact with said housing along a central portion of each of said rods; and means for securing said rods to a supporting structure whereby said rods, bands and motor can be cantilevered from said supporting structure.
Claim 13
Dependent Claim
81 words
The combination defined in claim 9 wherein each of said bands is angled through an obtuse angle at its point of contact with each of said rods, with the respective rod being disposed at the vertex of the angle, and the respective band extending from said vertex substantially tangentially with respect to a circle of the least diameter sufficient for the circle to touch each of said rods on the opposite side thereof from its point of securement to said bands.
