Abstract
Abstract A vertical spindle machine having a lubricant pump which is driven in conjunction with the spindle has a lubricator fixedly connected to the spindle for providing the spindle bearings with an initial charge of lubricant upon start-up. This initial charge satisfies the lubricant needs of the bearings until the pump reaches full operating speed, and is delivering a continuous supply of lubricant to the bearings. During rotation of the spindle, the pump delivers the lubricant to the lubricator where a predetermined charge is retained, within a first chamber while the excess flows onto the bearings; upon stopping the spindle rotation, this charge flows from the first chamber into a second chamber of the lubricator where it is available for discharge upon start-up once again.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
137 words
The combination, comprising a rotor adapted to rotate about an upright axis, a lubricant pump operatively connected with said rotor and adapted to be driven in conjunction with said rotor, a start-up lubricator fixedly connected to said rotor, and means defining a lubricant passageway between said pump and said startup lubricator for delivering lubricant from said pump to said start-up lubricator during rotation of said rotor, said start-up lubricator comprising: a. first means for receiving and retaining a predetermined charge of said lubricant from said pump via said lubricant passageway during rotation of said rotor, while simultaneously releasing lubricant in excess of said predetermined charge; b. second means for receiving and retaining said charge of lubricant from said first means during termination of said rotation, and for discharging said charge of lubricant upon initiation of said rotation.
Claim 2
Dependent Claim
137 words
The combination, comprising a rotor adapted to rotate about an upright axis, a lubricant pump operatively connected with said rotor and adapted to be driven in conjunction with said rotor, a start-up lubricator fixedly connected to said rotor, and means defining a lubricant passageway between said pump and said startup lubricator for delivering lubricant from said pump to said start-up lubricator during rotation of said rotor, said start-up lubricator comprising: a. first means for receiving and retaining a predetermined charge of said lubricant from said pump via said lubricant passageway during rotation of said rotor, while simultaneously releasing lubricant in excess of said predetermined charge; b. second means for receiving and retaining said charge of lubricant from said first means during termination of said rotation, and for discharging said charge of lubricant upon initiation of said rotation.
Claim 3
Dependent Claim
71 words
The combination according to claim 1 wherein said first means defines a receiving chamber adapted to retain said charge during rotation of said rotor, said passageway extending between said pump and said receiving chamber, said first means having at least one opening therein for releasing said lubricant during rotation thereof, said second means defining a discharge chamber having at least one opening therein for receiving and discharging said charge of lubricant.
Claim 4
Dependent Claim
18 words
The combination according to claim 2 wherein said receiving and discharging chambers are annular, and surround said rotor.
Claim 5
Dependent Claim
69 words
The combination according to claim 3 wherein said first means includes a bottom opening located therein which opens into the bottom of said receiving chamber, said discharge chamber being generally U-shaped, the open end of said U-shaped discharge chamber facing upwardly and disposed under said bottom opening whereby said discharge chamber receives said charge of lubricant upon termination of said rotation, and discharges said charge upon initiating said rotation.
Claim 6
Dependent Claim
18 words
The combination according to claim 4 wherein said lubricant passageway is at least partially disposed within said rotor.
Claim 7
Dependent Claim
42 words
The combination according to claim 5 wherein said first means includes a downwardly extending annular overflow lip which defines the said outermost edge of said bottom opening, said lubricant being discharged radially outwardly over said overflow lip during rotation of said rotor.
Claim 8
Dependent Claim
25 words
The combination of claim 4, and further including frame means disposed adjacent said rotor, and bearing means supported between said rotor and said frame means.
Claim 9
Dependent Claim
36 words
The combination according to claim 7 wherein said frame means includes a diverting opening disposed therein for receiving at least a portion of said lubricant released from said start-up lubricator during rotation of said start-up lubricator.
Claim 10
Dependent Claim
43 words
The combination according to claim 8 wherein said first means has a top opening disposed therein, said diverting opening being disposed so as to receive at least a portIon of the lubricant released through said top opening during rotation of said start-up lubricator.
Claim 11
Dependent Claim
35 words
The combination according to claim 8 and further including distributor means disposed between said start-up lubricator and said frame means for permitting only a portion of said lubricant released to pass thru said diverting opening.
Claim 12
Dependent Claim
27 words
The combination according to claim 9 and further including shelf means for directing substantially all of said lubricant released through said top opening through said diverting opening.
Claim 13
Dependent Claim
28 words
The combination according to claim 8 wherein said diverting opening is disposed so as to receive lubricant released from said bottom opening during rotation of said start-up lubricator.
Claim 14
Dependent Claim
44 words
The combination of claim 12 and further including distributor means disposed between said stationary means and said start-up lubricator for permitting only a portion of said lubricant released through said bottom opening during rotation of said start-up lubricator to pass through said diverting opening.
Claim 15
Dependent Claim
106 words
The combination according to claim 7 and further including an annular vapor sealing member, said sealing member being fixedly connected to said frame means and extending inwardly in a generally radial direction toward said rotor, and into said U-shaped discharge chamber to a locus located below the liquid level of said charge contained with said discharge chamber prior to initiating rotation of said start-up lubricator, said first means including an annular downwardly extending sealing lip which defines the outermost edge of said bottom opening, said sealing lip being disposed radially inward from said vapor sealing means and extending to a locus located below said liquid level.
Claim 16
Dependent Claim
19 words
The combination set forth in claim 4 including means defining a plurality of noncommunicating compartments within said discharge chamber.
Claim 17
Dependent Claim
43 words
