Abstract
Abstract A tool block comprises plates providing therebetween a tool holder guide channel for preventing movement of a tool holder along two of three orthogonal axes while permitting slidable adjustment relative to a workpiece along the third or adjustment axis. A pair of preload blocks normally clamp the tool holder against movement along the adjustment axis. A pair of forked shaped wedges straddle the tool holder and are adjustably received in recesses cut in opposite sides of the tool holder. Each wedge has a set of ramp shaped cam surfaces inclined along the adjustment axis for cooperating with a set of mating ramp shaped cam follower surfaces on the tool holder recesses to overcome the clamping preload of the preload block and slide the tool holder in one direction along the adjustment axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
199 words
A tool block comprising: a. a tool holder support having a tool holder guide channel extending along an adjustment axis for slidably guiding a tool holder along said adjustment axis while preventing movement along a transverse axis mutually orthogonal thereto; b. a tool holder slidably received in said guide chanNel for holding a cutting tool and finely adjusting the position thereof relative to a workpiece, said tool holder having a recess in a side thereof for guiding cam means and having cam follower means in said recess for cooperating with said cam means to slidably and finely adjust said tool holder along said adjustment axis; c. preload means slidably received on said tool holder for normally preventing said tool holder from sliding along said adjustment axis by biasing said tool holder against said tool holder support; and d. cam means guided by said recess and transversely adjustable therein along said transverse axis for overcoming said bias provided by said preload means and sliding said tool holder along said adjustment axis on said tool holder support and said preload means by forcing said cam follower means along a forcing axis through said tool holder substantially parallel to said adjustment axis.
Claim 2
Dependent Claim
199 words
A tool block comprising: a. a tool holder support having a tool holder guide channel extending along an adjustment axis for slidably guiding a tool holder along said adjustment axis while preventing movement along a transverse axis mutually orthogonal thereto; b. a tool holder slidably received in said guide chanNel for holding a cutting tool and finely adjusting the position thereof relative to a workpiece, said tool holder having a recess in a side thereof for guiding cam means and having cam follower means in said recess for cooperating with said cam means to slidably and finely adjust said tool holder along said adjustment axis; c. preload means slidably received on said tool holder for normally preventing said tool holder from sliding along said adjustment axis by biasing said tool holder against said tool holder support; and d. cam means guided by said recess and transversely adjustable therein along said transverse axis for overcoming said bias provided by said preload means and sliding said tool holder along said adjustment axis on said tool holder support and said preload means by forcing said cam follower means along a forcing axis through said tool holder substantially parallel to said adjustment axis.
Claim 3
Dependent Claim
222 words
A tool block comprising: a. tool holder support having a tool holder quide channel extending along an adjustment axis for slidably guiding a tool holder along said adjustment axis while preventing movement along two transverse axes mutually orthogonal thereto; b. a tool holder slidably received in said guide channel for holding a cutting tool and finely adjusting the position thereof relative to a workpiece, said tool holder having a recess in a side thereof for guiding cam means and having a pair of cam follower means in said recess for cooperating with said cam means to adjust said tool holder along said adjustment axis; c. preload slidably received on said tool holder for normally preventing said tool holder from sliding along said adjustment axis by biasing said tool holder against said tool holder support; and d. a pair of cam means guided by said recess and transversely adjustable therein along one of said transverse axes for overcoming said bias provided by said preload means and sliding said tool holder means along said adjustment axis on said tool holder support and preload means by forcing one of said cam follower means in one direction along said adjustment axis when one of said cam means is adjusted and the other cam follower means in the other direction when the other cam means is adjusted.
Claim 4
Dependent Claim
222 words
A tool block comprising: a. tool holder support having a tool holder quide channel extending along an adjustment axis for slidably guiding a tool holder along said adjustment axis while preventing movement along two transverse axes mutually orthogonal thereto; b. a tool holder slidably received in said guide channel for holding a cutting tool and finely adjusting the position thereof relative to a workpiece, said tool holder having a recess in a side thereof for guiding cam means and having a pair of cam follower means in said recess for cooperating with said cam means to adjust said tool holder along said adjustment axis; c. preload slidably received on said tool holder for normally preventing said tool holder from sliding along said adjustment axis by biasing said tool holder against said tool holder support; and d. a pair of cam means guided by said recess and transversely adjustable therein along one of said transverse axes for overcoming said bias provided by said preload means and sliding said tool holder means along said adjustment axis on said tool holder support and preload means by forcing one of said cam follower means in one direction along said adjustment axis when one of said cam means is adjusted and the other cam follower means in the other direction when the other cam means is adjusted.
Claim 5
Dependent Claim
266 words
A tool block comprising: a. a tool holder support having a tool holder guide channel extending along an adjustment axis for slidably guiding a tool holder along said adjustment axis while preventing movement along two transverse axes mutually orthogonal thereto, said tool holder support comprising a pair of spaced side plates for providing two side surfaces for said channel, each said side plate having cam grooves for guiding cam means; b. a tool holder slidably received in said guide channel for holding a cutting tool and finely adjusting the position thereof relative to a workpiece, said tool holder having a pair of recess in opposite sides thereof for cooperating with said side plate grooves to guide said cam means, each said recess having a pair of ramp shaped cam follower surfaces oppositely inclined along said adjustment axis for cooperating with said cam means to adjust said tool holder along said adjustment axis; c. preload means slidably received on said tool holder for normally preventing said tool holder from sliding along said adjustment axis by biasing said tool holder against said tool holder support; and d. cam means comprising a pair of fork shaped wedges spaced axially along said adjustment axis and transversely adjustable in said side plate grooves and tool holder recesses along one of said transverse axes for overcoming said bias of said preload means and forcing one of said cam follower surfaces in one direction along said adjustment axis when one of said wedges is adjusted and the other of said cam follower means in the other direction when the other wedge is adjusted.
