Abstract
Abstract In a preferred form, the subject invention relates to assemblies adapted to enable repetitive positioning of cutting tools, and in a specific form comprises a driver or holder adapted to be carried by a machine tool spindle and having a bore therein arranged to receive a tool adapter so that a cutting surface carried thereon can be positioned in only one radial position relative to the spindle. The driver or holder includes a pin extending transversely of the bore which is slightly offset from the longitudinal axis of the bore. The pin is adapted to mate with a complementary shaped depression extending transversely of the adapter on the rear portion thereof and which is also offset from the longitudinal axis thereof a similar amount to that of the pin so that the two can be mated only when the adapter and cutting surface carried thereby is situated in one radial position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A quick-change tool assembly, said assembly comprising: driver means adapted to be carried by a rotary machine spindle, said driver means having a longitudinally extending bore therein and a locator and drive element extending transversely across said bore and being laterally offset with respect to the longitudinal axis thereof; and an adapter means adapted to carry a cutting element and having a shank including a shank portion insertable into said bore, said shank portion having a surface at one extremity thereof through which the longitudinal axis of said shank passes, said surface having a portion complementary in shape to a portion of the outer surface of said element and being engageable therewith to provide predetermined rotary location and drive for said adapter means from and relative to said driver means thereby allowing repetitive positioning of said adapter means relative to said driver means.
Claim 2
Dependent Claim
143 words
A quick-change tool assembly, said assembly comprising: driver means adapted to be carried by a rotary machine spindle, said driver means having a longitudinally extending bore therein and a locator and drive element extending transversely across said bore and being laterally offset with respect to the longitudinal axis thereof; and an adapter means adapted to carry a cutting element and having a shank including a shank portion insertable into said bore, said shank portion having a surface at one extremity thereof through which the longitudinal axis of said shank passes, said surface having a portion complementary in shape to a portion of the outer surface of said element and being engageable therewith to provide predetermined rotary location and drive for said adapter means from and relative to said driver means thereby allowing repetitive positioning of said adapter means relative to said driver means.
Claim 3
Dependent Claim
23 words
A quick-change tool assembly according to claim 1 wherein said element is A pin that is fixed with respect to said driver means.
Claim 4
Dependent Claim
25 words
A quick-change tool assembly according to claim 1 wherein said driver means has a tapered outer portion adapting its engagement directly with a rotary spindle.
Claim 5
Dependent Claim
46 words
A quick-change tool assembly according to claim 1 wherein said surface of said adapter means includes a depression having a deepest portion offset from the longitudinal axis of said bore an amount substantially equal to the amount of offset of the longitudinal axis of said element.
Claim 6
Dependent Claim
77 words
A quick-change tool assembly according to claim 1 wherein said driver means has an aperture in a wall thereof angularly disposed with respect to the longitudinal axis of said bore and communicating with said bore, said aperture carrying a screw means with a ball nose extremity, said adapter means having a scalloped portion on said shank portion adapted to be engaged by said ball nose extremity to maintain said driver means and adapter means in fixed relationship.
Claim 7
Dependent Claim
57 words
A quick-change tool assembly according to claim 1 wherein said driver means includes a body having a front face and said adapter means includes a flange with a rear surface engageable with said front face of said body as said portion of said surface at the extremity of said shank of said adapter means engages said element.
