Compact Selective Head Engine Lathe FOR toolroom work, especially where it is desirable tohave a large number of speeds available, the improved,geared-head engine lathe manufactured by the LehmannMachine Company, St. Louis, Mo., will be found welladapted. The lathe is built in a number of sizes and 16spindle speeds are provided, ranging from to 422 the 16-in. lathe, and to 330 on the 22-in. ma-chine. These speeds are in almost exact geometrical propor-. Lehmann Selective Geared Head Engine Lathe tion and are obtained without the use of a travel of the 10 gears used in the head stock is moderateat all spindle speeds, which tends to make a quiet runningmachine. No safety or interlocking device is required toavoid engagement of different gear ratios at the same time,as the particular design makes it impossible for this accidentto occur. Made of high carbon steel and running on ball bearings, all shafts with sliding members are provided with four keysmilled integral with the shaft. Each shifting member isoperated by a ring which runs in a groove completely encir-cling it, the compensating mechanism which connects thering with the operating shaft being of substantial construe -
