This lathe swings 16^ in. over shears, and 10 in. over car-riage, and with a six-foot bed takes 2 ft. 8 in. between a six-foot bed the weight is approximately 2,100 lbs. Thatthe machine is capable of continuous operation under heavy cutswill be evidenced by the statement that it will handle, withoutany signs of distress, a cut yi in. deep by /a feed in 60 pointcarbon steel at a peripheral speed of 75 feet per BOTTOM VIEW OF C.^RRIAGE. below the ways for the carriage, it is not necessary to notchthe bridge for clearance, and thus its rigidity is maintained. The compound rest is made hea\-y to withstand the strainsimposed upon it by the modern high speed steels. The clamp-ing device for the swivel is of a new construction operated by asingle belt which is located convenient to the operator. Theclamping mechanism consists of a V-shaped clamping ring of M. M.
