Abstract
Abstract The chain lubricating system of this invention includes an oil reservoir and a partially submerged sprocket wheel. The sprocket wheel is loosely carried on a stationary axle mounted within the reservoir to permit both rotation and lateral slidable movement thereon. The teeth of the sprocket are characterized to urge oil into the links and rollers of the drive chain as it is moved over the rotating sprocket.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
An apparatus for lubricating a continuous chain comprising a reservoir for holding a preselected amount of a lubricating fluid, said reservoir having a front wall, a rear wall, a bottom wall and two side walls, a stationary axle carried within said reservoir and fixed to said sidewalls at a centrally located point, a sprocket wheel loosely carried on said axle to permit rotation and slidable lateral movement thereon, said sprocket wheel having teeth and means on said teeth for carrying a lubricating quantity of a lubricating fluid upward from said reservoir during rotation for deposit on a continuous chain passing thereover.
Claim 2
Independent Claim
101 words
An apparatus for lubricating a continuous chain comprising a reservoir for holding a preselected amount of a lubricating fluid, said reservoir having a front wall, a rear wall, a bottom wall and two side walls, a stationary axle carried within said reservoir and fixed to said sidewalls at a centrally located point, a sprocket wheel loosely carried on said axle to permit rotation and slidable lateral movement thereon, said sprocket wheel having teeth and means on said teeth for carrying a lubricating quantity of a lubricating fluid upward from said reservoir during rotation for deposit on a continuous chain passing thereover.
Claim 3
Dependent Claim
43 words
The apparatus of claim 1, wherein at least a portion of said front and rear walls of said reservoir has a height of less than said side walls to thereby provide a means for ingress and egress of a continuous chain carried therethrough.
Claim 4
Dependent Claim
12 words
The apparatus of claim 2, wherein said reservoir includes a removeable cover.
Claim 5
Dependent Claim
16 words
The apparatus of claim 3 wherein said teeth on said sprocket wheel have a non-smooth surface.
Claim 6
Dependent Claim
14 words
The apparatus of claim 4, wherein said teeth possesses a plurality of axial grooves.
Claim 7
Dependent Claim
18 words
The apparatus of claim 5, including an adjustable mounting means for fixing said reservoir to a support member.
Claim 8
Dependent Claim
22 words
The apparatus of claim 6, wherein said bottom wall of said reservoir includes a threaded stud for receiving said adjustable mounting means.
Claim 9
Dependent Claim
132 words
In an improved wheel line irrigating system having a wheeled motorized drive carriage wherein said drive carriage includes a continuous drive chain having an upper and lower flight which connects a power source carried on said drive carriage to a sprocket fixed to an axle of said wheeled drive carriage, said improvement comprising the inclusion of a lubricant holding reservoir positioned intermediate said axle and said power source and in alignment with said continuous chain, said reservoir having a sprocket rotatably carried on a laterally extending axle mounted within said reservoir and over which said upper flight of said drive chain passes, said sprocket being adopted with teeth and means on said teeth for carrying said lubricant from said reservoir and depositing same on said continuous drive chain as it passes thereover.
Claim 10
Dependent Claim
132 words
In an improved wheel line irrigating system having a wheeled motorized drive carriage wherein said drive carriage includes a continuous drive chain having an upper and lower flight which connects a power source carried on said drive carriage to a sprocket fixed to an axle of said wheeled drive carriage, said improvement comprising the inclusion of a lubricant holding reservoir positioned intermediate said axle and said power source and in alignment with said continuous chain, said reservoir having a sprocket rotatably carried on a laterally extending axle mounted within said reservoir and over which said upper flight of said drive chain passes, said sprocket being adopted with teeth and means on said teeth for carrying said lubricant from said reservoir and depositing same on said continuous drive chain as it passes thereover.
Claim 11
Dependent Claim
35 words
The improved system of claim 8, wherein said sprocket is loosely held on said laterally extending axle to permit lateral movement thereon and thereby permit said sprocket to automatically align itself with said continuous chain.
Claim 12
Dependent Claim
16 words
The improved system of claim 9, wherein said teeth on said sprocket have a non-smooth surface.
