A NEW TYPE OF RING MACHINE that cuts 80,000 jar rings in a ten hour run isshown in the accompanying illustration. It is arranged to cutup tubing of varying diameters, the cutting knife making 15,-000 revolutions a minute. To cut a tube of particular diameterthere is a guide which is inserted in the machine in the follow-ing manner : The nuts E, F, F^ are first loosened and then thefront iron guide and the back brass guide are then both re-moved from the machine, the latter by loosening the fourscrews C, G, G^, G\ and the two studs //and H^ to the left. and to the right, are screwed in until the index points for the twoscales plates /and / indicate the proper number. When thisis done the guides may be inserted and the nuts E, F, andF^ are screwed on, and then four tubes are inserted throughthe front guides and the scale which is found on the rear partis then adjusted for the thickness of the rings to be cut andthe machine is then ready for operation. The adjustment ofthe rear scale is made in the following manner: The indexhand is screwed to the zero point by means of the studs, thenthe machine is revolved by hand until the support has exactlyreached its lowest position.
