Abstract
Abstract A lubricant supply device adapted to direct lubricant from a source of pressurized lubricant to apparatus to be lubricated. The device is provided with a rotatable chamber containing a limited quantity of lubricant so that in the event of a failure in the supply of lubricant to the device, lubricant contained within the chamber is centrifugally pumped to the apparatus to be lubricated in order to maintain a limited continuity of lubricant supply.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
236 words
A lubricant supply device for receiving a lubricant under pressure from a lubricant supply means and delivering lubricant to an apparatus to be lubricated, said lubricant supply device comprising: inlet means for receiving lubricant under pressure from the lubricant supply means; a chamber rotatable about an axis of rotation, said chamber being operatively connected to and having communication with said inlet means for receiving lubricant under pressure therefrom; manifold means operatively rotatable with said chamber and disposed radially outwardly of said inlet means; passage means extending between said inlet means and said manifold means for delivering lubricant under pressure from said inlet means to said manifold means; an outlet means extending from said manifold means for delivering lubricant therefrom to the apparatus to be lubricated; and chamber outlet metering means between said chamber and said manifold means for delivering a minor proportion of a total amount of lubricant supplied to said manifold means when lubricant under pressure is being supplied by said inlet means to said chamber and to said passage means, said chamber outlet metering means being positioned in said chamber radially outwardly of said axis of rotation of said chamber and radially outwardly of said passage means whereby upon cessation of the supply of lubricant under pressure to said inlet means, any lubricant in said chamber is centrifugally pumped through said chamber outlet metering means to said manifold means and through said outlet means.
Claim 2
Dependent Claim
236 words
A lubricant supply device for receiving a lubricant under pressure from a lubricant supply means and delivering lubricant to an apparatus to be lubricated, said lubricant supply device comprising: inlet means for receiving lubricant under pressure from the lubricant supply means; a chamber rotatable about an axis of rotation, said chamber being operatively connected to and having communication with said inlet means for receiving lubricant under pressure therefrom; manifold means operatively rotatable with said chamber and disposed radially outwardly of said inlet means; passage means extending between said inlet means and said manifold means for delivering lubricant under pressure from said inlet means to said manifold means; an outlet means extending from said manifold means for delivering lubricant therefrom to the apparatus to be lubricated; and chamber outlet metering means between said chamber and said manifold means for delivering a minor proportion of a total amount of lubricant supplied to said manifold means when lubricant under pressure is being supplied by said inlet means to said chamber and to said passage means, said chamber outlet metering means being positioned in said chamber radially outwardly of said axis of rotation of said chamber and radially outwardly of said passage means whereby upon cessation of the supply of lubricant under pressure to said inlet means, any lubricant in said chamber is centrifugally pumped through said chamber outlet metering means to said manifold means and through said outlet means.
Claim 3
Dependent Claim
26 words
A lubricant supply device as claimed in claim 1 wherein said inlet means comprises a passage disposed coaxially with said axis of rotation of said chamber.
Claim 4
Dependent Claim
41 words
A lubricant supply device as claimed in claim 1 wherein said chamber outlet metering means includes a passage having a dimensional cross-sectional area less than a dimensional cross-sectional area of said passage means between said inlet means and said manifold means.
Claim 5
Dependent Claim
28 words
A lubricant supply device as claimed in claim 1 wherein said manifold means is annular in form and disposed coaxially with said axis of rotation of said chamber.
