Abstract
Abstract A side-dressing device for grinding wheels comprising a carriage which makes a reciprocating slide motion relative to the body of the dressing device; a pair of main shafts attached to said carriage and rotatable relative to said carriage; shafts rotatable within said main shafts, set eccentrically to the axis of said main shafts and fitted with a rotary diamond truing cutter at their respective outer ends; and a drive mechanism for rotating said rotatable shafts in opposite directions to each other; said pair of rotary diamond truing cutters being so arranged that they may reciprocate and slide on each side surface of a grinding wheel to be dressed which is being rotated at a fixed position on the wheel slide. Said main shafts being externally fitted with gears, which mesh with gears which are linked with the feed shaft to cause the former gears to rotate in opposite directions; and said feed shaft being turned by a certain angle so that the rotary diamond truing cutter may be brought up to the grinding wheel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
168 words
A side-dressing device for grinding wheels comprising: 1. a carriage mounted for reciprocatingly sliding movement relative to the body of the dressing device; 2. a pair of main shafts provided on said carriage and mounted for turning movement relative to said carriage; 3. rotatable shafts each being freely rotatable relative to said respective main shafts and positioned within said main shafts and being eccentrically mounted in relationship to the axis of said main shafts, rotary diamond truing cutters being mounted at the outer ends of said rotatable eccentrically mounted shafts with the grinding wheel to be dressed being positioned between said rotary diamond truing cutters; 4. a drive mechanism for rotating said pair of rotatable eccentrically mounted shafts in opposite directions to each other; and 5. an automatic feeding device for applying said pair of rotary diamond truing cutters to said grinding wheel by a turning movement of said main shafts responsive to a reciprocating slide motion of said pair of rotary diamond truing cutters with said carriage.
Claim 2
Dependent Claim
168 words
A side-dressing device for grinding wheels comprising: 1. a carriage mounted for reciprocatingly sliding movement relative to the body of the dressing device; 2. a pair of main shafts provided on said carriage and mounted for turning movement relative to said carriage; 3. rotatable shafts each being freely rotatable relative to said respective main shafts and positioned within said main shafts and being eccentrically mounted in relationship to the axis of said main shafts, rotary diamond truing cutters being mounted at the outer ends of said rotatable eccentrically mounted shafts with the grinding wheel to be dressed being positioned between said rotary diamond truing cutters; 4. a drive mechanism for rotating said pair of rotatable eccentrically mounted shafts in opposite directions to each other; and 5. an automatic feeding device for applying said pair of rotary diamond truing cutters to said grinding wheel by a turning movement of said main shafts responsive to a reciprocating slide motion of said pair of rotary diamond truing cutters with said carriage.
Claim 3
Dependent Claim
18 words
a pair of main shafts provided on said carriage and mounted for turning movement relative to said carriage;
Claim 4
Dependent Claim
18 words
a pair of main shafts provided on said carriage and mounted for turning movement relative to said carriage;
Claim 5
Dependent Claim
64 words
A side-dressing device according to claim 1, wherein said main shafts have gears fitted on their external surfaces and said gears are made to mesh with gears which are connected to feed shafts for rotating said former gears of said main shafts in opposite directions to each other, while at the same time, said feed means rotates said feed shafts through a definite angle.
Claim 6
Dependent Claim
77 words
A side-dressing device according to claim 1, wherein said feed means comprises a swing plate, a ratchet wheel fitted to a feed shaft, a ratchet pawl provided on said swing plate and engaging said ratchet wheel, and a piston interlocked with reciprocating slide motion of rotary diamond truing cutters to rotate said swing plate in a definite direction and to rotate said feed shaft by a preset angle through engagement of said ratchet wheel and ratchet pawl.
Claim 7
Dependent Claim
62 words
rotatable shafts each being freely rotatable relative to said respective main shafts and positioned within said main shafts and being eccentrically mounted in relationship to the axis of said main shafts, rotary diamond truing cutters being mounted at the outer ends of said rotatable eccentrically mounted shafts with the grinding wheel to be dressed being positioned between said rotary diamond truing cutters;
Claim 8
Dependent Claim
62 words
rotatable shafts each being freely rotatable relative to said respective main shafts and positioned within said main shafts and being eccentrically mounted in relationship to the axis of said main shafts, rotary diamond truing cutters being mounted at the outer ends of said rotatable eccentrically mounted shafts with the grinding wheel to be dressed being positioned between said rotary diamond truing cutters;
Claim 9
Dependent Claim
19 words
a drive mechanism for rotating said pair of rotatable eccentrically mounted shafts in opposite directions to each other; and
Claim 10
Dependent Claim
19 words
a drive mechanism for rotating said pair of rotatable eccentrically mounted shafts in opposite directions to each other; and
Claim 11
Dependent Claim
31 words
A side-dressing device according to claim 2, wherein a backlash-eliminating means is furnished which at all times urges the gear fitted to said main shaft to rotate in a definite direction.
Claim 12
Dependent Claim
42 words
an automatic feeding device for applying said pair of rotary diamond truing cutters to said grinding wheel by a turning movement of said main shafts responsive to a reciprocating slide motion of said pair of rotary diamond truing cutters with said carriage.
Claim 13
Dependent Claim
42 words
an automatic feeding device for applying said pair of rotary diamond truing cutters to said grinding wheel by a turning movement of said main shafts responsive to a reciprocating slide motion of said pair of rotary diamond truing cutters with said carriage.
