. American engineer . RING MILL A new machine of unusual interest and embodying manyoriginal and novel features has recently been designed by theRochester Boring Machine Company, of Rochester, N. this machine comes within the general classification ofa boring mill, a more accurate name would be, a boring, milling,drilling and tapping machine, since it is arranged to performall of these functions proficientlj-. accurately and conveniently,ft can also be used for splining, oil grooving and thread this may seem to be a very w-ide range of work for onemachine, reference to the illustration will show that the designis without complication. On the contrary it is marked by ex-treme simplicity when its size and range of work are taken inconsideration. Possibly the most striking feature is the central-ized control that permits every change of feed, speed or trav-erse in every direction, as well as the starting, stopping and re-versing, to be made from a position of the operator which allows. Arrangement of Gearing for Feed Changes and Reverse. him to closely observe the work of the cutter at the same arrangement in the head will not allow two conflicting leversto be engaged at the same time. All the driving and feeding mechanism is centralized in thesaddle or head, insuring maximum efficiency of power by theL-limination of many shafts, joints and gears. The aim through-jut the machine has been to make the drive as direct as possible,so that the power is used for doing work and not for overcomingthe friction of the machine itself. When the machine is motordriven, the power is applied direct to the vertical driving shaftand when belt driven it is applied through bevel gears froma horizontal shaft. A clutch for starting and stopping is pro-vided in the main driving pulley of the belt driven type. One feature in particular that has made possible the central-ized control and simple design, is the ingenious method employedfor feeding the spindle.
