Abstract
Abstract The combination of a cyclically operative periodically actuated bearing assembly and/or bearing surface lubricating system with a machine tool lubricated thereby including component parts thereof relatively movable about or along bearing assemblies and/or coacting bearing surfaces according to a predetermined machining cycle by feeding means responsive to signals from automatic cyclically operative control means therefore, including means operative to actuate the periodic lubricating system responsive to selected signals from the control means to the feeding means so that periodic operation of the lubricating system is coordinated with the relative movement of component parts of the machine tool, and monitoring means activated periodically with the lubricating system and operative to interrupt the machining cycle whenever the lubricating system fails to complete its operating cycle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
226 words
A machine tool including first supporting means for a cutting tool, a cutting tool supported thereby, second supporting means for a given workpiece to be machined, bearing means arranged to accommodate relative movement between said first and said second supporting means, feeding means interconnecting said first supporting means and said second supporting means, feed control means for said feeding means operative automatically to actuate said feeding means to produce sequentially relative retracting and feeding movement between said cutting tool and a given workpiece on said second supporting means according to a predetermined feeding cycle in which a predetermined final feeding portion thereof constitutes a finish feed, A lubricating apparatus cyclically operable to distribute metered quantities of a fluid lubricant sequentially to a plurality of different locations within said machine tool including said bearing means and said feeding means, lubricant control means operative to actuate said lubricating apparatus in response to a signal from said feed control means transmitted during a portion of the predetermined feeding cycle other than said final feeding portion thereof, and lubricating apparatus monitoring means including sensing means actuated and reset during a single lubricating cycle, said monitoring means being activated when said lubricating apparatus is actuated and operative whenever said lubricating apparatus fails to complete a lubricating cycle to render inoperative said feed control means and thereby interrupt said predetermined feeding cycle.
Claim 2
Dependent Claim
226 words
A machine tool including first supporting means for a cutting tool, a cutting tool supported thereby, second supporting means for a given workpiece to be machined, bearing means arranged to accommodate relative movement between said first and said second supporting means, feeding means interconnecting said first supporting means and said second supporting means, feed control means for said feeding means operative automatically to actuate said feeding means to produce sequentially relative retracting and feeding movement between said cutting tool and a given workpiece on said second supporting means according to a predetermined feeding cycle in which a predetermined final feeding portion thereof constitutes a finish feed, A lubricating apparatus cyclically operable to distribute metered quantities of a fluid lubricant sequentially to a plurality of different locations within said machine tool including said bearing means and said feeding means, lubricant control means operative to actuate said lubricating apparatus in response to a signal from said feed control means transmitted during a portion of the predetermined feeding cycle other than said final feeding portion thereof, and lubricating apparatus monitoring means including sensing means actuated and reset during a single lubricating cycle, said monitoring means being activated when said lubricating apparatus is actuated and operative whenever said lubricating apparatus fails to complete a lubricating cycle to render inoperative said feed control means and thereby interrupt said predetermined feeding cycle.
Claim 3
Dependent Claim
44 words
A machine tool as described in claim 1, and, in addition, counting means arranged to count the number of cycles completed by said feeding means and operative to maintain said lubrication control means inoperative for a predetermined number of cycles of said feeding means.
Claim 4
Dependent Claim
42 words
A machine tool as described in claim 1 wherein said machine tool comprises a grinding machine, said cutting tool comprises a grinding wheel rotatably mounted on said first supporting means, and the given workpiece is mounted rotatably upon said second supporting means.
Claim 5
Dependent Claim
83 words
A machine tool as described in claim 3 wherein said lubricating apparatus includes at least one metering unit assembly each including a plurality of reciprocating metering units respectively connected with a plurality of locations to be lubricated and mutually interconnected to be reciprocated sequentially responsive to the delivery of pressurized lubricating fluid to each said metering unit assembly, and a metering pump operated by said lubrication control means to deliver a quantity of lubricating fluid sufficient to cycle every said metering unit assembly.
Claim 6
Dependent Claim
47 words
A machine tool as described in claim 4 wherein 28 said metering pump operated by said lubrication control means is arranged to deliver a predetermined quantity of lubricating fluid in excess of the amount sufficient to cycle every said metering unit assembly through one complete lubricating cycle.
Claim 7
Dependent Claim
91 words
A machine tool as described in claim 3 wherein said lubricating apparatus monitoring means Comprises a feeding cycle stop means operative to render said feed control means inoperative, a timer means actuated when said lubricating apparatus is actuated and operative after a predetermined time interval in excess of the time required to complete a single lubricating cycle to energize said feeding cycle stop means, and means operative during each complete lubricating cycle to render said feeding cycle stop means inoperative when a lubricating cycle is completed before said timer means operates.
Claim 8
Dependent Claim
93 words
A machine tool as described in claim 3 including at least one additional feeding means, at least one additional feed control means each operative to actuate one said additional feeding means, at least one additional lubricating apparatus cyclically operative to distribute predetermined metered quantities of a fluid lubricant to each said additional feeding means, and at least one additional lubrication control means each actuated by one said additional feed control means and operative in response to a signal from said additional feed control means connected thereto to actuate one said additional lubricating apparatus.
Claim 9
Dependent Claim
28 words
A machine tool as described in claim 7 wherein one said additional lubricating apparatus is operative to lubricate bearing means and feeding means for a truing tool mechanism.
Claim 10
Dependent Claim
28 words
A machine tool as described in claim 7 wherein one said additional lubricating apparatus is operative to lubricate bearing means and table feeding means for a movable table.
Claim 11
Dependent Claim
78 words
A machine tool as described in claim 9, and, in addition, counting means arranged to count the number of cycles completed by said table feeding means and operative after one said additional lubricating apparatus is actuated during a given feeding cycle to maintain inoperative during a predetermined number of succeeding feeding cycles said additional lubrication control means operative to actuate said additional lubricating apparatus operative to lubricate said bearing means and said feeding means for said movable table.
