Abstract
Abstract A lubrication system for a machine, having bearings rotatably supporting one or more journals, such as in a turbine or generator. The system comprises a lubricant reservoir having an open top portion and closed side and bottom portions. The reservoir may be a cylindrical reservoir or an underground reinforced concrete reservoir which would be lined with a material impervious to the oil. The lubricant conduits are cut and fitted outside of an independent of the reservoir. The conduits and pumping equipment are then mounted on inner and outer surfaces of a plate to form a unitary plate structure. The plate structure is lowered onto a shelf portion surrounding the open portion of the reservoir. The conduits inside of the reservoir are secured by adjustable supports to the reservoir. The plate structure is detachably secured to the reservoir thereby enclosing the reservoir.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
173 words
In a lubrication system for a machine having bearings rotatably supporting at least one journal, said system comprising in combination a closed lubricant reservoir having an open top portion, a plate structure, said plate structure having an outer and inner surface, conduit means external to said reservoir and pumping means external to said reservoir, said conduit means including at least one pressurized lubricant conduit, said external means being mounted on said outer surface of said plate structure, said external conduit means including a guard pipe encompassing at least one pressurized lubricant conduit, said guard pipe being adapted to contain said pressurized lubricant, conduit means internal to reservoir and pumping means internal to said reservoir, said internal means being attached to said inner surface of said plate structure, said external means cooperating with corresponding internal means to supply lubricant to said bearings, means to detachably secure said plate structure to the top of said reservoir thereby closing said open top portion, and means to adjustably secure said conduit and pumping means to said reservoir.
Claim 2
Dependent Claim
173 words
In a lubrication system for a machine having bearings rotatably supporting at least one journal, said system comprising in combination a closed lubricant reservoir having an open top portion, a plate structure, said plate structure having an outer and inner surface, conduit means external to said reservoir and pumping means external to said reservoir, said conduit means including at least one pressurized lubricant conduit, said external means being mounted on said outer surface of said plate structure, said external conduit means including a guard pipe encompassing at least one pressurized lubricant conduit, said guard pipe being adapted to contain said pressurized lubricant, conduit means internal to reservoir and pumping means internal to said reservoir, said internal means being attached to said inner surface of said plate structure, said external means cooperating with corresponding internal means to supply lubricant to said bearings, means to detachably secure said plate structure to the top of said reservoir thereby closing said open top portion, and means to adjustably secure said conduit and pumping means to said reservoir.
Claim 3
Dependent Claim
23 words
The structure recited in claim 1 wherein the lubricant reservoir comprises a cylindrical body portion, two end portions, and an open top portion.
Claim 4
Dependent Claim
48 words
The system recited in claim 1 and further including means for draining the lubricant escaping from the bearings, the guard pipe communicating with said drain means, at least one drain opening in the plate structure, and said guard pipe communicating with said drain opening to discharge lubricant therethrough.
Claim 5
Dependent Claim
172 words
In a lubrication system for a machine having bearings rotatably supporting at least one journal, said system comprising a closed lubricant reservoir having an open top portion, a plate structure, said plate structure having an outer and inner surface, conduit means external to said reservoir and pumping means external to said reservoir, said external means being mounted on said outer surface of said plate structure, conduit means internal to reservoir and pumping means internal to said reservoir, said internal means being attached to said inner surface of said plate structure, said external means cooperating with corresponding internal means to supply lubricant to said bearings, means to detachably secure said plate structure to the top of said reservoir thereby closing said open top portion, means to adjustably secure said conduit and pumping means to said reservoir, said lubricant reservoir comprising a reinforced concrete channel, said channel having an open top portion, said channel lined with a material impervious to the lubricant, and said material dependent on said channel for its shape and support.
Claim 6
Dependent Claim
172 words
In a lubrication system for a machine having bearings rotatably supporting at least one journal, said system comprising a closed lubricant reservoir having an open top portion, a plate structure, said plate structure having an outer and inner surface, conduit means external to said reservoir and pumping means external to said reservoir, said external means being mounted on said outer surface of said plate structure, conduit means internal to reservoir and pumping means internal to said reservoir, said internal means being attached to said inner surface of said plate structure, said external means cooperating with corresponding internal means to supply lubricant to said bearings, means to detachably secure said plate structure to the top of said reservoir thereby closing said open top portion, means to adjustably secure said conduit and pumping means to said reservoir, said lubricant reservoir comprising a reinforced concrete channel, said channel having an open top portion, said channel lined with a material impervious to the lubricant, and said material dependent on said channel for its shape and support.
Claim 7
Dependent Claim
42 words
The structure recited in claim 4 wherein the channel has two end portions on the ends of the channel, said end portions lined with a material impervious to the lubricant, and said material dependent on the channel for its shape and support.
Claim 8
Dependent Claim
12 words
The structure recited in claim 5 wherein the channel is a parallelepiped.
