Abstract
Abstract A cyclic type lubrication system for lubricating an intermittently operated device having operating cycles of varying time durations. The system includes a control and monitoring mechanism for initiating a lubrication cycle after the device has been operated through a predetermined number of operating cycles and for providing an indication whether the lubricating cycle has been completed during a predetermined number of operating cycles of the device after initiation of the lubrication cycle.

Claim 1
Independent Claim
172 words
A lubrication and monitoring system for supplying lubricant to an intermittently operating device having varying operating cycle time durations comprising pressurized lubricant supply means, cyclic type lubricant distribution means having an element movable back and forth in response to the actuation of said distribution means through a complete lubricating cycle, means for controlling the initiation of a lubricating cycle comprising switch means closed by the lubricated device upon initiation of and throughout an operating cycle of the lubricated device, means connected to said switch means for generating a signal of predetermined duration in response to each closure of said switch means, and means coupled to said signal generating means and responsive to a predetermined number of said signals of predetermined duration to activate said distribution means to initiate a lubrication cycle, and means responsive to the back and forth movement of said element and operatively connected to said initiation control means for providing an indication whether a lubricating cycle has been completed within a predetermined number of operating cycles of the device.
Claim 2
Dependent Claim
172 words
A lubrication and monitoring system for supplying lubricant to an intermittently operating device having varying operating cycle time durations comprising pressurized lubricant supply means, cyclic type lubricant distribution means having an element movable back and forth in response to the actuation of said distribution means through a complete lubricating cycle, means for controlling the initiation of a lubricating cycle comprising switch means closed by the lubricated device upon initiation of and throughout an operating cycle of the lubricated device, means connected to said switch means for generating a signal of predetermined duration in response to each closure of said switch means, and means coupled to said signal generating means and responsive to a predetermined number of said signals of predetermined duration to activate said distribution means to initiate a lubrication cycle, and means responsive to the back and forth movement of said element and operatively connected to said initiation control means for providing an indication whether a lubricating cycle has been completed within a predetermined number of operating cycles of the device.
Claim 3
Dependent Claim
256 words
