Abstract
Abstract A segmental arcuate ring springable to varying diameters has two parallel rods secured near its center and extending axially of the arc of the ring. An arcuate yoke is secured to the opposite ends of the rods and extends generally parallel to ring to two spaced motor mounts. One form of the mounts is two inwardly turned and aligned pintles. Each pintle carries an angularly adjustable mounting block, and the mounting blocks each carry a mounting plate swingable about the axes of the pintles. The mounting plates have plural holes for mounting a fan motor with the axis of the motor and a fan driven thereby at different distances from the axes of the pintles, including coincident intersecting relation of the fan axis to the axes of the pintles. A modified form shows nonpivotable motor mounts directly on ends of a yoke formed from a single rod with a center section folded upon itself and extending axially to abutted connection to a similarly bent rod forming the segmental arcuate ring.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
63 words
A support frame for a fan and fan motor comprising, a segmental metal ring bendable to Different generally circular diameters, connecting means forming a post connected to said ring and projecting normally to the plane thereof, means forming a yoke connected to the end of said post in generally parallel relation to said ring, and motor-mounting means on the ends of said yoke.
Claim 2
Dependent Claim
63 words
A support frame for a fan and fan motor comprising, a segmental metal ring bendable to Different generally circular diameters, connecting means forming a post connected to said ring and projecting normally to the plane thereof, means forming a yoke connected to the end of said post in generally parallel relation to said ring, and motor-mounting means on the ends of said yoke.
Claim 3
Dependent Claim
80 words
A support frame as defined in claim 1 in which said mounting means include inwardly turned pintle pins on the ends of said yoke, bearing blocks angularly adjustably mounted on said pins, and mounting plate means secured to said bearing blocks in parallel relation to said pins, said plate means defining holes spaced diametrically of said yoke and adapted to receive mounting bolts of a motor to support the motor with its shaft normal to places passed through said pins.
Claim 4
Dependent Claim
25 words
A support frame as defined in claim 1 in which said mounting means comprises parallel series of holes formed in the ends of said yoke.
Claim 5
Dependent Claim
28 words
A support frame as defined in claim 2 in which said plate means define parallel series of holes for receiving mounting bolts at different distances from said pins.
Claim 6
Dependent Claim
24 words
A support frame as defined in claim 2 in which said plate means are separate plates, each secured to one of said bearing blocks.
Claim 7
Dependent Claim
28 words
A support frame as defined in claim 2 in which said bearing blocks have clamp means for adjustably securing the blocks in angularly adjusted positions on said pins.
Claim 8
Dependent Claim
36 words
A support frame as defined in claim 1 in which said post comprises spaced parallel rods secured near the center of said ring, said yoke comprising a separate part secured to the end of the rods.
Claim 9
Dependent Claim
109 words
In combination with a fan motor having a shaft and a fan blade, plate means secured to said motor in normal relation to said shaft, spaced bearing means on said plate means defining aligned pintle-receiving openings parallel to said plate means, a yoke having inwardly turned pintles on its ends angularly adjustably received in said pintle openings, connecting post means rigidly connected to said yoke and projecting generally normally to the plane thereof at a distance from said pintles which is greater than the radius of said fan blade, and a segmental ring of bendable material connected to said connecting means in spaced generally parallel relation to said yoke.
Claim 10
Dependent Claim
109 words
In combination with a fan motor having a shaft and a fan blade, plate means secured to said motor in normal relation to said shaft, spaced bearing means on said plate means defining aligned pintle-receiving openings parallel to said plate means, a yoke having inwardly turned pintles on its ends angularly adjustably received in said pintle openings, connecting post means rigidly connected to said yoke and projecting generally normally to the plane thereof at a distance from said pintles which is greater than the radius of said fan blade, and a segmental ring of bendable material connected to said connecting means in spaced generally parallel relation to said yoke.
Claim 11
Dependent Claim
38 words
The combination as defined in claim 8 in which said plate means are secured to the back of said motor, said connecting post means comprising spaced parallel rods secured to the centers of said yoke and said ring.
Claim 12
Dependent Claim
35 words
The combination as defined in claim 8 in which said plate means are spaced separate plates, each connected to one of said bearing means, and set screws in said bearing means engageable with said pintles.
Claim 13
Dependent Claim
26 words
A fan support frame as defined in claim 1 having a fan motor connected to said motor mounting means in overhanging spaced relation to said post.
Claim 14
Dependent Claim
93 words
A fan support frame as defined in claim 1 in which said segmental ring is formed of a single integral bar bent into coplanar segments at its ends, with its midsection doubled upon itself and bent axially of the plane of the ends, said yoke forming means also being formed of a single integral bar bent into coplanar segments at its ends with its midsection doubled upon itself and bent axially of the plane of the ends, the axially extending midsections of said bars being rigidly connected in opposed end to end relation.
Claim 15
Dependent Claim
33 words
A fan support frame as defined in claim 12 in which said motor mounting means are flattened portions on the ends of said yoke, each defining a hole for receiving a mounting fastener.
Claim 16
Dependent Claim
23 words
A fan support frame as defined in claim 13 in which said flattened portions each have a series of said holes formed therein.
