Abstract
Abstract A boring tool assembly is comprised of a vertically disposed spindle rotatably mounted within a spindle housing about a vertical axis, spindle drive means adapted to rotate the spindle, a horizontal guide track rigidly secured to the bottom of the spindle, a block member movably received in the guide track, a cutting tool operatively secured to the block member, and a movable block adjustment means within the spindle engaging the block member for moving it along the guide track. The block adjustment means includes a shaft member movably mounted within the spindle and bearing against a bearing portion of the block member. The shaft member is movable between a first position and a second position by a drive means so that movement of the shaft member forces the block member to move horizontally along the guide track.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
235 words
A boring tool assembly comprising a support; a spindle rotatably mounted on said support; spindle drive means adapted to rotate said spindle about a rotational axis; a tool support member mounted on said spindle in such a manner that it is movable toward and away from said rotational axis of said spindle and is held against rotational movement with respect to said spindle; said tool support member being provided with means for operatively securing a tool thereto; an elongated member mounted within said spindle in such a manner that it is longitudinally movable along said rotational axis of said spindle and is held against rotational movement with respect to said spindle; and cooperating means between said tool support member and said elongated member for transferring longitudinal movement of said elongated member to Said tool support member, thereby causing lateral movement of said tool support member with respect to said rotational axis of said spindle; said cooperating means including two spaced apart and parallel inclined surfaces on one of said members, one of said inclined surfaces being formed by a plate having opposite flat sides; and a first and second rotatable bearing on the other of said members, said first bearing being interposed between said two inclined surfaces, said second bearing being spaced apart from said first bearing, said second bearing and said first bearing embracing said plate therebetween and rotatably engaging said opposite flat sides.
Claim 2
Dependent Claim
235 words
A boring tool assembly comprising a support; a spindle rotatably mounted on said support; spindle drive means adapted to rotate said spindle about a rotational axis; a tool support member mounted on said spindle in such a manner that it is movable toward and away from said rotational axis of said spindle and is held against rotational movement with respect to said spindle; said tool support member being provided with means for operatively securing a tool thereto; an elongated member mounted within said spindle in such a manner that it is longitudinally movable along said rotational axis of said spindle and is held against rotational movement with respect to said spindle; and cooperating means between said tool support member and said elongated member for transferring longitudinal movement of said elongated member to Said tool support member, thereby causing lateral movement of said tool support member with respect to said rotational axis of said spindle; said cooperating means including two spaced apart and parallel inclined surfaces on one of said members, one of said inclined surfaces being formed by a plate having opposite flat sides; and a first and second rotatable bearing on the other of said members, said first bearing being interposed between said two inclined surfaces, said second bearing being spaced apart from said first bearing, said second bearing and said first bearing embracing said plate therebetween and rotatably engaging said opposite flat sides.
Claim 3
Dependent Claim
228 words
A boring tool assembly comprising a support; a spindle rotatably mounted on said support; spindle drive means adapted to rotate said spindle about a rotational axis; a tool support member mounted on said spindle in such a manner that it is movable toward and away from said rotational axis of said spindle and is held against rotational movement with respect to said spindle; said tool support member being provided with means for operatively securing a tool thereto; an elongated member mounted within said spindle in such a manner that it is longitudinally movable along said rotational axis of said spindle and is held against rotational movement with respect to said spindle; and cooperating means between said tool support member and said elongated member for transferring longitudinal movement of said elongated member to said tool support member, thereby causing lateral movement of said tool support member with respect to said rotational axis of said spindle; said cooperating means including at least one inclined surface on one of said members, said inclined surface being formed by a flat plate having opposite flat surfaces; a first bearing on the other of said members, said bearing rotatably engaging said inclined surface, and a second bearing also on said other of said members, said second bearing and said first bearing being spaced apart and rotatably engaging said opposite flat surfaces of said plate.
Claim 4
Dependent Claim
228 words
A boring tool assembly comprising a support; a spindle rotatably mounted on said support; spindle drive means adapted to rotate said spindle about a rotational axis; a tool support member mounted on said spindle in such a manner that it is movable toward and away from said rotational axis of said spindle and is held against rotational movement with respect to said spindle; said tool support member being provided with means for operatively securing a tool thereto; an elongated member mounted within said spindle in such a manner that it is longitudinally movable along said rotational axis of said spindle and is held against rotational movement with respect to said spindle; and cooperating means between said tool support member and said elongated member for transferring longitudinal movement of said elongated member to said tool support member, thereby causing lateral movement of said tool support member with respect to said rotational axis of said spindle; said cooperating means including at least one inclined surface on one of said members, said inclined surface being formed by a flat plate having opposite flat surfaces; a first bearing on the other of said members, said bearing rotatably engaging said inclined surface, and a second bearing also on said other of said members, said second bearing and said first bearing being spaced apart and rotatably engaging said opposite flat surfaces of said plate.
Claim 5
Dependent Claim
32 words
A boring tool assembly according to claim 2 wherein said tool support members include means for moving said bearings toward each other to increase the tightness with which they embrace said plate.
Claim 6
Dependent Claim
19 words
A boring tool assembly according to claim 3 wherein said means for moving said bearings is a lead screw.
Claim 7
Dependent Claim
29 words
A boring tool assembly according to claim 2 wherein said plate is mounted on one end of said elongated member and said bearings are on said tool support member.
Claim 8
Dependent Claim
52 words
A boring tool assembly according to claim 2 wherein said elongated member includes a flange extending longitudinally from one of its ends so as to give said one end a T-shaped cross-sectional configuration; said plate being detachably mounted to said flange so as to give said one end an I-shaped cross-sectional configuration.
