| Hyde & Meyer - patent attorneys
This invention relates to improvements in a lathe attachment, which is particularly useful in the cutting of threads. One of the objects of the present invention is to provide means associated with the tool rest of a lathe or the like adapted to hold the tool into engagement with the work up to a predetermined point at which time the tool is suddenly moved away from the work so as to end a tool cut exactly at a predetermined point. It is possible with this device to make progressively deeper cuts and to withdraw the tool at exactly the same point every time and to thereby produce a result not heretofore possible to my knowledge. Another object of the present invention is to provide a device as described above together with means for resetting the device after each cut by means of a very simple manual operation.
