Description: |
| "It is the object of my invention to produce an automatic saw-grinder in which the non-grinding intervals between the grinding of successive teeth are materially lessened in length, so that the proportion of actual grinding time to the whole time of the operation is materially increased; in which the travel of the grinding wheel over the teeth may be accurately and easily controlled, and a path-controlling cam may be used which approximates a plane and ordinarily needs but slight adjustment from the plane shape; in which all the necessary adjustments are easily made by devices readily accessible to the operator and in general capable of manipulation which the machine is in operation; and in which the adjustments for tooth-pitch and tooth-height are interrelated, so that they may be properly and easily set for standard dimensions of saws in co-ordination with each other... My present invention is a development of my prior Patent No. 1,179,556..." |
