Abstract
Abstract A feed device for grinding machines, for example, circular and thread grinding machines, in which the grinding tool and the work-piece are slidable relatively to one another, and in which a trimming device provided with one or more trimming tools is mounted on a slidable adjusting or trimming carriage which before the commencement of a trimming operation is fed a predetermined amount closer to the grinding tool, whereby in order to compensate for the decrease in size of the grinding disk resulting from the adjustment, a change in position of the grinding tool takes place with reference to the work-piece.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
A feed device for grinding machines having a support with which a grinding wheel is operatively associated and on which it is supported and in which the support and rotatable work-piece are slidable relative to each other comprising: a slidable adjusting carriage; a trimming device mounted on said carriage, said trimming device being adapted to have a trimming tool disposed therein; means for shifting said adjusting carriage transversely to the grinding wheel axis, said shifting means including a threaded spindle slidably disposed in the support and in threaded engagement with said adjusting carriage; control means interconnecting the support and said adjusting carriage to provide an additional shifting of the adjusting carriage; said control means including a slide member which is carried by the support and which is shifted during the adjustment operation transversely to the grinding carriage guide, said slide member having a groove or slot formed therein; and a slide pin which is guided in said groove or slot to thereby impart additional shifting to the threaded spindle.
Claim 2
Dependent Claim
169 words
A feed device for grinding machines having a support with which a grinding wheel is operatively associated and on which it is supported and in which the support and rotatable work-piece are slidable relative to each other comprising: a slidable adjusting carriage; a trimming device mounted on said carriage, said trimming device being adapted to have a trimming tool disposed therein; means for shifting said adjusting carriage transversely to the grinding wheel axis, said shifting means including a threaded spindle slidably disposed in the support and in threaded engagement with said adjusting carriage; control means interconnecting the support and said adjusting carriage to provide an additional shifting of the adjusting carriage; said control means including a slide member which is carried by the support and which is shifted during the adjustment operation transversely to the grinding carriage guide, said slide member having a groove or slot formed therein; and a slide pin which is guided in said groove or slot to thereby impart additional shifting to the threaded spindle.
Claim 3
Dependent Claim
20 words
The device of claim 1 wherein said groove or slot has a profile the shape of which is empirically determined.
Claim 4
Dependent Claim
36 words
The device of claim 1 including a template fixed on said adjusting carriage; and a guide pin fixed on said slide member and in contact with said template to control the movement of the adjusting carriage.
Claim 5
Dependent Claim
15 words
The device of claim 1 wherein said slide member is slidably disposed on the support.
Claim 6
Dependent Claim
36 words
The device of claim 4 including a template fixed on said adjusting carriage; and a guide pin fixed on said slide member and in contact with said template to control the movement of the adjusting carriage.
Claim 7
Dependent Claim
34 words
The device of claim 1 wherein said slide pin is connected to a longitudinally slidable axial bearing on the threaded spindle for bringing about additional shifting of said threaded spindle and said trimming device.
Claim 8
Dependent Claim
41 words
The device of claim 1 wherein said slide member is positioned in the support; and said slide pin is connected to an axial bearing on the threaded spindle for bringing about additional shifting of said threaded spindle and said trimming device.
Claim 9
Dependent Claim
36 words
The device of claim 7 including a template fixed on said adjusting carriage; and a guide pin fixed on said slide member and in contact with said template to control the movement of the adjusting carriage.
Claim 10
Dependent Claim
23 words
The device of claim 6 wherein said template is adjustable so that its control edge may be positioned at a plurality of angles.
