Abstract
Abstract An oscillating strainer for a cutting tool coolant supply system for a machine tool. The strainer is slidably mounted on the coolant system fixed supply pipe by a slidably mounted support tube. The tube carrying the strainer is oscillated upwardly and downwardly by a support arm which has one end fixed to said tube and the other end pivotally connected to the lower end of a support rod. The upper end of the support rod is eccentrically mounted on the end of a horizontally disposed, rotating shaft so as to provide an upward and downward oscillating movement to the support rod, which oscillating movement is in turn conveyed to the coolant strainer through the support arm and support tube.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
In a machine tool having a rotating shaft and a cutting tool coolant system having a coolant reservoir and a fixed coolant supply pipe extended into the reservoir, the combination comprising: a. a coolant strainer operatively disposed in said reservoir; b. means movably supporting said coolant strainer on said fixed supply pipe for movement longitudinally of said supply pipe, with said supply pipe extended into said strainer; and, c. means for oscillating said means for movably supporting the strainer on said supply pipe to provide an oscillating motion longitudinally of said supply pipe to said strainer to prevent a build-up of dirt and the like on the outer surface of said strainer.
Claim 2
Dependent Claim
