Abstract
Abstract A boring and facing head for machine tools, in which the tool slide is radially displaceable on a rotating carrier. For radial adjustment of the tool slide, the slide is provided with a rack engaged by a gear mounted on and rotating with the slide carrier, the gear being turned for adjustment purposes by a nonrotating adjusting member extending along the axis of rotation of the carrier and projecting out the back of the housing, the projecting end of the adjusting member being provided with a scale which can be read while the carrier is rotating. The rotating carrier is driven by a shaft parallel to but offset radially from the axis of rotation. In one form of the invention, gauging stops are provided on a turret, for cooperation with a dial gauge or an end gauge, in order to determine accurately the position of the axially movable adjusting member which serves to adjust the radial position of the tool slide on the rotating slide carrier.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
A boring and facing head comprising a housing, a slide carrier mounted on said housing for rotation about an axis of rotation, a tool slide mounted on and rotating bodily with said carrier and adjustable on said carrier in a direction radially of said axis of rotation, a feed element coaxial with said axis of rotation and displaceable in the direction of said axis, operating means operatively connecting said feed element to said tool slide to move said tool slide radially from axial movement of said feed element, characterized by an extension on said feed element extending to a position externally of said housing, and a graduated scale on the external portion of said extension.
Claim 2
Dependent Claim
115 words
A boring and facing head comprising a housing, a slide carrier mounted on said housing for rotation about an axis of rotation, a tool slide mounted on and rotating bodily with said carrier and adjustable on said carrier in a direction radially of said axis of rotation, a feed element coaxial with said axis of rotation and displaceable in the direction of said axis, operating means operatively connecting said feed element to said tool slide to move said tool slide radially from axial movement of said feed element, characterized by an extension on said feed element extending to a position externally of said housing, and a graduated scale on the external portion of said extension.
Claim 3
Dependent Claim
21 words
A construction as defined in claim 1, further comprising a scale reading mark including an enlargement lens for reading said scale.
Claim 4
Dependent Claim
38 words
A construction as defined in claim 1, wherein said feed element is a bar fixed against rotation, and further comprising means including a rotatable shaft parallel to and spaced radially from said bar for rotating said slide carrier.
Claim 5
Dependent Claim
43 words
A construction as defined in claim 3, wherein said means for rotating said slide carrier includes an internal gear fixed to said slide carrier coaxially with the axis of rotation thereof and a gear on said rotatable shaft meshing with said internal gear.
Claim 6
Dependent Claim
56 words
A construction as defined in claim 1, wherein said operating means comprises a first toothed rack extending axially on said feed element, a second toothed rack extending radially on said tool slide, and an operating gear mounted in and rotating bodily with said carrier and engaging both said first toothed rack and said second toothed rack.
Claim 7
Dependent Claim
35 words
A construction as defined in claim 5, wherein said first toothed rack is formed on a sleeve mounted for rotation on said feed element and held against axial movement with respect to said feed element.
Claim 8
Dependent Claim
22 words
A construction as defined in claim 1, further comprising a dial gauge holder mounted on said external extension of said feed element.
Claim 9
Dependent Claim
32 words
A construction as defined in claim 7, further comprising means externally of said hOusing for holding a gauge block in position to cooperate with a dial gauge mounted in said gauge holder.
Claim 10
Dependent Claim
30 words
A construction as defined in claim 7, further comprising means for holding at least one adjustable stop in position to cooperate with a dial gauge mounted in said gauge holder.
Claim 11
Dependent Claim
44 words
A construction as defined in claim 7, further comprising a rotatable turret mounted on said housing and carrying a plurality of adjustable stops, any selected one of which may be brought into position to cooperate with a dial gauge mounted on said gauge holder.
