Abstract
Abstract A precision turning machine is provided with an automatic hydraulic tracer control unit including a stylus adapted to engage a template. A carriage supports the template and is shiftable horizontally on an angle relative to the turning axis and in incremental steps in response to indexing of a wheel having a plurality of individually adjustable stop screws. The carriage and template are shiftable in precise increments between successive passes of the cutting tool to produce automatic successive roughing and finishing cutting operations according to the contour of the template.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
Apparatus adapted to be mounted on a machine tool, said apparatus comprising means for supporting a template adapted to be engaged by a stylus of an automatic tracer control unit, a frame, a carriage, means mounted on said frame and supporting said carriage for linear movement, means on said carriage for supporting the template, a movable stop member supported by said frame, a plurality of individually adjustable stop elements mounted on said stop member, means mounted on said frame for moving said stop member in incremental steps for positioning each said stop element at a predetermined station, and means mounted on said carriage for engaging each said stop element when positioned at said station to effect shifting of said carriage and the template in incremental steps according to the setting of said stop elements relative to said stop member.
Claim 2
Dependent Claim
139 words
Apparatus adapted to be mounted on a machine tool, said apparatus comprising means for supporting a template adapted to be engaged by a stylus of an automatic tracer control unit, a frame, a carriage, means mounted on said frame and supporting said carriage for linear movement, means on said carriage for supporting the template, a movable stop member supported by said frame, a plurality of individually adjustable stop elements mounted on said stop member, means mounted on said frame for moving said stop member in incremental steps for positioning each said stop element at a predetermined station, and means mounted on said carriage for engaging each said stop element when positioned at said station to effect shifting of said carriage and the template in incremental steps according to the setting of said stop elements relative to said stop member.
Claim 3
Dependent Claim
38 words
Apparatus as defined in claim 1 wherein said stop member comprises a wheel, said stop elements are mounted on said wheel in angularly spaced relation, and said moving means comprises a motor effective to index said stop member.
Claim 4
Dependent Claim
37 words
Apparatus as defined in claim 2 wherein each said stop element comprises a stop screw adjustable axially on said wheel, and including a head having a cam surface adapted to engage said means mounted on said carriage.
Claim 5
Dependent Claim
13 words
Apparatus as defined in claim 3 wherein said engaging means comprises a roller.
Claim 6
Dependent Claim
42 words
Apparatus as defined in claim 2 wherein said wheel is rotatable on an axis extending parallel to the direction of movement of said carriage, and each said stop element is adjustable in a direction parallel to the rotatable axis of said wheel.
Claim 7
Dependent Claim
35 words
Apparatus as defined in claim 1 including spring means urging said carriage in a direction to effect engagement of said means mounted on said carriage with each said stop element when positioned at said station.
Claim 8
Dependent Claim
33 words
Apparatus as defined in claim 1 wherein said means for supporting the templaTe comprise a rail mounted on said carriage, and means for adjusting the position of said rail relative to said carriage.
Claim 9
Dependent Claim
48 words
Apparatus as defined in claim 1 in combination with a hydraulic tracer control unit including a stylus adapted to engage the template, said stylus being removable axially to effect actuation of a hydraulic control valve, and solenoid actuated means for shifting said stylus axially to operate said valve.
Claim 10
Dependent Claim
43 words
Apparatus as defined in claim 1 including means for mounting said frame on the machine tool to effect movement of said carriage in a direction forming an acute angle relative to a vertical plane extending through the rotary axis of the machine tool.
Claim 11
Dependent Claim
41 words
Apparatus as defined in claim 9 wherein said supporting means for the template is effective to position the template generally parallel to the rotary axis of the machine tool and in angular relation to the direction of movement of said carriage.
