Abstract
Abstract An apparatus for dressing a grinding disc and, in particular, for dressing the flanks of a grinding disc for a worm or thread grinding machine. The apparatus has a stationary frame and a carriage is movable in the frame radially of the disc. A pair of opposed dressing elements are carried on the disc end of the carriage and slide thereon axially of the disc. A pair of slides on the other end of the carriage move parallel to the direction of movement of the dressing elements. Levers pivoted in the carriage connect each slide with a respective dressing element and each slide has a feeler on one end engageable with a templet in the frame. The edge of each feeler is a knife edge curved in a plane normal to the direction of travel of the carriage. Each templet has a knife edge for engagement with the edge of a respective feeler and extending at an angle to the edge of the respective feeler. Each templet is adjustable in the frame laterally with respect to the direction of travel of the carriage and angularly about a pair of axes extending angularly to each other and to the direction of travel of the carriage. The feelers are, preferably, adjustable on the slides in the direction in which the feeler edges extend.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
245 words
In a dressing device for dressing a grinding disc, especially a grinding disc for a worm or thread-grinding machine: a frame adapted to be fixedly mounted relative to the axis of the disc to be dressed, a carriage guided in the frame for movement radially of the disc, first and second dressing elements on said carriage at the disc end thereof in opposed axially spaced relation relative to the disc and movable transversely in the axial direction of the disc to dress the sides of the disc, a pair of slides slidable transversely on said carriage at the end thereof opposite said disc and in a direction axially of said disc, a pair of levers pivoted in said carriage and each having one end connected to a respective one of said slides and the other end connected to a respective one of said first and second dressing elements, a feeler member on one end of one slide and on the opposite end of the other slide, a templet in the frame adjacent each feelEr member, said feeler members and templets having interengaging knife edges, the said edges on said feeler members being disposed in a plane normal to the direction of movement of said carriage and being curved in said plane, and means pivotally supporting said templets in said frame for angular adjustment about first and second axes angularly related to each other and to the direction of movement of said carriage in said frame.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
54 words
A dressing device according to claim 1, in which the said edges of said templets extend generally in the direction of movement of said carriage, the said first axes being disposed in a second plane parallel to the direction of movement of said carriage and said second axes being normal to said second plane.
Claim 4
Dependent Claim
30 words
A dressing device according to claim 2, in which the said first and second axes for each templet intersect at one end of the said edge of the respective templet.
Claim 5
Dependent Claim
37 words
A dressing device according to claim 2, in which said feeler members are mounted on said slides for adjustment thereon in said first mentioned plane lateral to the direction of movement of said slides on said carriage.
Claim 6
Dependent Claim
47 words
A dressing device according to claim 2, which includes a baseplate for each templet and having means thereon forming the respective said first and second axes, and means for adjusting said baseplates on said frame in a direction transverse to the direction of movement of said carriage.
Claim 7
Dependent Claim
41 words
A dressing device according to claim 4, which includes a support member on each baseplate pivotally connected thereto on the respective second axis, and a shaft rotatable in each support member on the respective first axis and supporting the respective templet.
Claim 8
Dependent Claim
45 words
A dressing device according to claim 6, which includes an abutment stud on each baseplate and an opposed abutment surface on each support member adapted to receive a gauge block therebetween for setting the position of the respective support member on the baseplate pertaining thereto.
Claim 9
Dependent Claim
17 words
A dressing device according to claim 2, in which the said edge of each templet is linear.
Claim 10
Dependent Claim
39 words
A dressing device according to claim 2, which includes a third dressing element on said carriage at the disc end thereof presented radially toward said disc and movable axially of the disc for dressing the periphery of the disc.
Claim 11
Dependent Claim
36 words
A dressing device according to claim 2, which includes resilient means acting between said first and second dressing elements for biasing said slides in a direction to press the feeler members thereon against the respective templets.
