SOUTH BEND LATHE WORKS We ~erve the right,to make improvements in design or price changes without notice. NEW MODEL SOUTH BEND LATHES BACK-GEARED, SCREW CUTTING, PRECISION LATHES The South Bend Lathe Works was established in South. Bend,' Indiana in 1906 and for thirty-one years has been : devoted to the manufacture of South Bend Lathes exclusively. The New Model Series "Nil and Series "H" Lathes shown in this catalog are the result of thirty-one years of ex­ perience in building lathes. Many improvements in design have been made, and some of them are shown for the first time in this catalog. More important is the superior quality of workmanship which is made possible by the highly special­ ized skill of our experienced employees and the excellent equipment of our shops. It has always been the policy of this company to produce a good lathe at a moderate price. The excellent performance of South Bend Lathes in industry has created a popular de- mand and enabled us to manufacture lathe units in large .- quantities. The increased production permits us to offer South Bend Lathes at prices which make them unquestionably the greatest lathe value per dollar invested. Accuracy and durability are built into every South Bend Lathe. Each lathe is operated and thoroughly tested before it leaves the factory. Given the proper care, a South Bend Lathe will last a lifetime. Many of our lathes that have been in constant use for ten to fifteen years are as accurate as the day they left the factory. ., South Bend Lathe Works Established November. 1906 425 EAST MADISON ST, --- SOUTH BEND, IND., U.
