Abstract
Abstract The present tool holder, for use in adjustably supporting a cutting tool, makes use of the same element and slide-face both for adjusting the holder in a first direction and for adjusting the holder in a direction perpendicularly oriented thereto. One support surface abuts against a cylindrical surface whilst another support surface abuts against a movable adjustingsupporting member in the tool body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
A cutting tool comprising a tool body (12) having a site provided thereon to receive a holder (10), said holder being adapted to hold a cutting bit (11) at one extremity thereof, said site presenting a first abutment surface of cylindrical shape, arranged for abutment with a first support surface on said holder, said support surface being of complementary cylindrical shape, said site presenting a second abutment surface remote from said first abutment surface, for abutment with a second support surface on said holder, said second abutment surface being provided by adjusting means (17) threadably engaged with the tool body adjacent said site, said adjusting means being displaceable toward and away from said site upon actuation of screw means (18) for effecting pivotal movement of said holder relative to said cylindrical abutment surface, and holding means for retaining said holder in adjusted position on said tool body said holding means comprising a locking screw (13) extending through said holder between said support surfaces while threadably engaging with the tool body (12).
Claim 2
Dependent Claim
171 words
A cutting tool comprising a tool body (12) having a site provided thereon to receive a holder (10), said holder being adapted to hold a cutting bit (11) at one extremity thereof, said site presenting a first abutment surface of cylindrical shape, arranged for abutment with a first support surface on said holder, said support surface being of complementary cylindrical shape, said site presenting a second abutment surface remote from said first abutment surface, for abutment with a second support surface on said holder, said second abutment surface being provided by adjusting means (17) threadably engaged with the tool body adjacent said site, said adjusting means being displaceable toward and away from said site upon actuation of screw means (18) for effecting pivotal movement of said holder relative to said cylindrical abutment surface, and holding means for retaining said holder in adjusted position on said tool body said holding means comprising a locking screw (13) extending through said holder between said support surfaces while threadably engaging with the tool body (12).
Claim 3
Dependent Claim
29 words
Device as defined in claim 1, in which the cylindrical surface is formed by a separate roller (15) provided between the holder and its site in the tool body.
Claim 4
Dependent Claim
36 words
Device as defined in claim 1, in which said first support surface of the holder is of cylindrical convex shape disposed for abutment against a complementary recess of cylindrical shape formed directly in the tool body.
Claim 5
Dependent Claim
20 words
Device as defined in claim 2, in which said roller (15) is disposed for rotational movement in the tool body.
Claim 6
Dependent Claim
35 words
Device as defined in claim 1, in which a surface (21) of member (17) acting as support surface is slidable on a facing surface on the holder (10) upon varying the positioning of said member.
Claim 7
Dependent Claim
54 words
Device as defined in claim 2, in which a swivelling nut (14) is provided in the tool body parallel to said roller (15) said nut being threadedly engaged with locking screw (13) so as to provide for said screw to take different angular positions upon pivoting movement of the holder around said roller (15).
Claim 8
Dependent Claim
55 words
Device as defined in claim 1, wherein said holder is provided with a set-screw (22) that is substantially parallel to said roller (15) and disengageable from said holder so as to provide for abutment against a fixed abutment surface on said tool body, thereby displacing the holder axially of said screw upon turning said screw.
Claim 9
Dependent Claim
45 words
Device as defined in claim 1, wherein spring elements (19) are associated with said locking screw (13) in the holder, for biasing said screw axially whereby urging said holder against support member (17) and roller (15) by spring action upon disengagement of said locking screw.
