Abstract
Abstract A vibratory coolant strainer for a cutting tool coolant supply system for a machine tool. A strainer screen assembly is rotatably mounted on a coolant system fixed supply pipe. A yoke is attached to the upper section of the strainer screen assembly and it is rapidly vibrated by a plural lobe cam which imparts a rapid vibratory or rotary oscillating motion to the strainer screen assembly so as to free it of metal chips and other dirt. The plural lobe cam is secured to a rotatably mounted shaft which is operatively supported in a housing attached to the supply pipe. The cam shaft may be driven by a suitable motor, or a belt or chain from a power source which is internal or external of the machine tool.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
140 words
In a machine tool having a cutting tool coolant system including a coolant reservoir and a fixed coolant supply pipe extended into the reservoir, the combination comprising: a. a coolant strainer assembly operatively disposed in said reservoir; b. means movably supporting said coolant strainer assembly on said fixed supply pipe for oscillating rotary movement thereabout, with said supply pipe extended into said strainer; c. means for oscillating in a rotary motion said means for movably supporting the strainer assembly on said supply pipe to provide a vibrating, rotary oscillating motion to said strainer assembly to prevent a build-up of dirt and the like on the outer surface of said strainer assembly; d. said means movably supporting said coolant strainer assembly including a mounting means attached to a strainer screen in said coolant strainer assembly; and, e. said oscillating means includes:
