Abstract
Abstract An improvement in a pivoted mounting system for a frictional brake or clutch which facilitates access to working parts for inspection and maintenance. Three sector shaped bodies or pods carry friction members operable to contact relatively rotatable plates. Each of the sector shaped pods is independently outwardly pivotable about either of its ends to expose the working parts. The pivot arrangement includes hooks on each end of each sector shaped pod for rotation about a pivot pin. Each sector shaped pod may alternatively be lifted out of the mechanism entirely by disengagement of the hooks of both ends from their pins.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
A pivoted and removable pod assembly for use in a friction coupling mechanism of the type wherein relative rotation between two bodies is controlled by selective engagement of friction members, comprising: a pod carrying friction members; hook fittings on said pod located near opposite ends of said pod, said hook fittings including slots open at one end, fixed mounting pins normally received by said hook fittings, whereby the hook fitting of either end of said pod is releasable from said pin in an outward direction and also pivotable about said pin by simply loosening the pins.
Claim 2
Dependent Claim
96 words
A pivoted and removable pod assembly for use in a friction coupling mechanism of the type wherein relative rotation between two bodies is controlled by selective engagement of friction members, comprising: a pod carrying friction members; hook fittings on said pod located near opposite ends of said pod, said hook fittings including slots open at one end, fixed mounting pins normally received by said hook fittings, whereby the hook fitting of either end of said pod is releasable from said pin in an outward direction and also pivotable about said pin by simply loosening the pins.
Claim 3
Dependent Claim
13 words
The pod assembly of claim 1 wherein the pod is generally sector shaped.
Claim 4
Dependent Claim
68 words
The pod assembly of claim 1 wherein the hook fitting near one end of said pod is formed as a double hook and the hook fitting near the other end of said pod is formed as a single hook so that the single hook of a pod may engage a pin while interleaved between hook elements of the double hook of an adjacent pod engaging the same pin.
Claim 5
Dependent Claim
36 words
The pod assembly of claim 1 wherein a plurality of friction devices operable to thrust pairs of friction pads outwardly in mutually opposite directions for engagement of the friction coupling meChanism are housed by the pod.
Claim 6
Dependent Claim
24 words
The pod assembly of claim 4 wherein said friction devices are fluid actuated and including means for selectively supplying fluid to said friction devices.
Claim 7
Dependent Claim
92 words
The pod assembly of claim 1 wherein the pod is generally sector shaped, said hook fittings being formed as extensions from opposite ends of the pod, the slot formed in the hook fitting of one end of the pod being disposed at an angle of substantially 120* with respect to the slot formed in the hook fitting of the opposite end of the pod, whereby three pod assemblies with three equally radially spaced mounting pins may be arranged in a generally annular plan between opposed friction surfaces of a friction coupling mechanism.
Claim 8
Dependent Claim
21 words
The pod assembly of claim 1 wherein the pod has spaced parallel bores formed therethrough, each bore housing a piston assembly.
Claim 9
Dependent Claim
16 words
The pod assembly of claim 7 wherein each bore houses a pair of opposed piston assemblies.
Claim 10
Dependent Claim
15 words
The pod assembly of claim 8 wherein the pairs of piston assemblies are independently operable.
Claim 11
Dependent Claim
20 words
The pod assembly of claim 1 including fluid cooling means mounted on the pod for cooling the friction coupling mechanism.
