Patent ID: 6932196

Claim:
A lubrication device for lubricating lubrication sites on a belt moving along a lubrication site path of movement, comprising: a lubricating apparatus operable to move back and forth parallel to the lubrication site path of movement between a starting position and a run path ending position, said lubricating apparatus including: a catch operable to pivot between a resting position, whereat said catch is not engaged with the belt, and a catch position, whereat said catch engages the belt such that the belt moves said lubricating apparatus parallel to the lubrication site path of movement at a speed of the belt from the starting position to the run path ending position; and a lubricating head operable to supply lubricant to a lubrication site on the belt while said catch is in the catch position and while said lubrication apparatus is moving parallel to the lubrication site path of movement from the starting position to the run path ending position; and two sensors spaced apart parallel to the lubrication site path of movement of the belt, said two sensors being operable to detect two lubrication sites spaced apart along the longitudinal axis of the belt, wherein said lubricating apparatus includes at least two lubricating heads spaced apart parallel to the lubrication site path of movement of the belt for supplying lubricant to the two lubrication sites.
