Abstract
Abstract A metering coolant valve is disclosed for directing fluid coolant onto each of a plurality of bits or tools mounted on a rotatable assembly. The plurality of tools are mounted upon a rotatable shaft for successively bringing each bit into contact with the work product to be machined. The fluid coolant is directed from a suitable supply to a distribution assembly fixedly disposed for rotative movement with the shaft. The fluid coolant is selectively distributed to each of the tools by a distribution assembly including a conduit or tube associated with each of the bits and having a first end disposed to direct the coolant onto the bit when it is in operative relationship with the work product and a second end selectively mounted upon the periphery of the shaft. As the shaft rotates with the distribution assembly, each conduit is brought into fluidexchange relationship with a metering assembly to thereby direct the coolant fluid through the corresponding conduit and onto that bit in operative relationship with the work product. The metering assembly includes a valve opening disposed adjacent the periphery of the shaft and disposable in alignment with one of the conduits as the second end of the conduit is rotated thereby. The valve opening is so dimensioned that the conduits are rotated into a fluid exchange relationship with the conduit opening for a predetermined angle of rotation to thereby control the amount of fluid coolant directed onto each of the bits and also the duration of time that the fluid is directed thereto. Further, a handle is fixedly attached to the metering assembly to ensure that the metering assembly does not rotate with the shaft when in operation and also to adjust selectively the position of the conduits with respect to the valve opening of the metering assembly to prevent further fluid coolant flow when the machine has ceased operation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
183 words
In machining apparatus including a plurality of tool elements rotatively mounted for successively operating upon a work product, the improvement comprising a variable coolant valve for supplying selectively a fluid coolant to one of the tool elements, said variable coolant valve comprising: a. means for defining an aperture disposed at a point fixed with respect to the rotation of the tool elements; b. means for receiving and directing the coolant fluid to said aperture; c. distributing means rotatable with the plurality of tool elements for providing conduits to each of the tool elements, said distributing means disposed so that upon rotation thereof each of the conduits is disposed successively in fluid transfer relation to said aperture; d. handle means attached to said means for defining an aperture so that the point fixed with respect to the rotation of the tool elements may be rotatably adjusted to vary coolant timing during operation or intentionally misalined to cut off coolant flow when not in operation; and e. means to vary the duration of the fluid transfer relationship between said aperture means and said distributing means.

Claim 3
Dependent Claim
48 words
A coolant valve as claimed in claim 1, wherein each of said conduits includes a first opening disposed to direct the fluid coolant onto an associated tool element, and a second opening disposed from the axis of rotation of the tool elements and angularly displaced from each other.
Claim 4
Dependent Claim
53 words
The coolant valve as claimed in claim 1, wherein said aperture is elongated to facilitate the continued fluid transfer relationship between said aperture and one of said conduits through a predetermined angle as said distributing means rotates, said angle selected to provide a predetermined amount of fluid coolant to each of said conduits.
Claim 5
Dependent Claim
49 words

Claim 6
Dependent Claim
52 words
The coolant valve as claimed in claim 1, wherein each of said conduits includes an opening for directing the coolant fluid onto its corresponding tool element, said opening being disposed from the tool element a distance sufficient to effect the evaporation of the fluid coolant upon contact with the corresponding tool element.
Claim 7
Dependent Claim
