Claim 1

Independent Claim 311 words

For use in machine tools, the combination comprising: a portable tool holder for preset tool mounting comprising transversely related first and second reference surfaces, and means for mounting tools therein such that the work-engaging edges thereof are adjustable in two transverse directions and spatially set in predetermined relation to both said reference surfaces; tool carrier means on the machine tool for mounting said holder having a third reference surface, interengageable with said first reference surface in operation and provided with an elongated recess formed inwardly thereof; means for detachably interconnecting said holder and carrier means comprising an elongated male dovetail member disposed wholly within said recess, beneath said third surface; said member having one rigid side formed along one longitudinal edge thereof, comprising a reference plane, and a second rigid side extending along the opposite longitudinal edge thereof comprising a planar surface divergent to said plane; a single female dovetail member fixed on said holder and having a rigid side comprising said second reference surface formed on a portion thereof depending from said first reference surface and adapted to enter said recess adjacent said one side of said male member in operation; detachable clamping means mountable between said holder and carrier means to extend substantially normal to said first and third reference surfaces and comprising an inclined portion underengageable with said divergently related surface of said male member, and cooperating means for forcing said inclined portion against said divergently related surface whereby to effect close fitting interfacial engagement between said first and third reference surfaces and clamp said second reference surface into close fitting engagement with said reference plane thereby to detachably interlock said holder on said carrier means; and stop means for locating said holder at predetermined selected positions along the length of said male member whereby to position the work-engaging edges of the tools in preselected three-dimensional spatial positions.

Claim 2

Dependent Claim 311 words

For use in machine tools, the combination comprising: a portable tool holder for preset tool mounting comprising transversely related first and second reference surfaces, and means for mounting tools therein such that the work-engaging edges thereof are adjustable in two transverse directions and spatially set in predetermined relation to both said reference surfaces; tool carrier means on the machine tool for mounting said holder having a third reference surface, interengageable with said first reference surface in operation and provided with an elongated recess formed inwardly thereof; means for detachably interconnecting said holder and carrier means comprising an elongated male dovetail member disposed wholly within said recess, beneath said third surface; said member having one rigid side formed along one longitudinal edge thereof, comprising a reference plane, and a second rigid side extending along the opposite longitudinal edge thereof comprising a planar surface divergent to said plane; a single female dovetail member fixed on said holder and having a rigid side comprising said second reference surface formed on a portion thereof depending from said first reference surface and adapted to enter said recess adjacent said one side of said male member in operation; detachable clamping means mountable between said holder and carrier means to extend substantially normal to said first and third reference surfaces and comprising an inclined portion underengageable with said divergently related surface of said male member, and cooperating means for forcing said inclined portion against said divergently related surface whereby to effect close fitting interfacial engagement between said first and third reference surfaces and clamp said second reference surface into close fitting engagement with said reference plane thereby to detachably interlock said holder on said carrier means; and stop means for locating said holder at predetermined selected positions along the length of said male member whereby to position the work-engaging edges of the tools in preselected three-dimensional spatial positions.

Claim 3

Dependent Claim 41 words

The combination of claim 1, wherein said male dovetail member is removably mounted in said recess between parallel spaced walls formed at right angles to said third reference surface and comprising lateral limits of an elongated groove portion of said recess.

Claim 4

Dependent Claim 50 words

The combination of claim 2, and means for locating said male member in said groove portion comprising plural rotatable eccentrics carried by said male member and engageable with said spaced walls for adjustably locating said male member in said groove, and means for locking the same between said walls thereof.

Claim 5

Dependent Claim 70 words

The combination of claim 1, said stop means including fixed stop means carried by said male member at spaced locations therealong for selected engagement by adjustable stop means mounted on said holder whereby the latter may be locked to said carrier means at selected locations along the longitudinal axis of said male member and said work-engaging edges located in predetermined three-dimensional locations relative to reference parameters of the machine tool.
