The Vernon Machine Co., Inc., Worcester, Mass., is now building the 11 inch lathe shown in the accompanying illustration. The machine is driven by a four-step cone pulley and single back-gears, thus providing eight changes of spindle speed. The spindle is made of high-carbon steel and finished to size by grinding; it is carried in bronze-lined bearings which have ample oiling facilities and means of compensation for wear. The end thrust of the spindle is supported by a step bolted to the end of the headstock. The tailstock is of the offset type which allows the compound rest to be set parallel to the bed; in addition, the tailstock can be set off center to provide for the performance of taper turning operations.
The carriage has a very stiff bridge and long bearings on the vees; it is securely gibbed to the bed and the compound rest is adequately supported by it. The apron is
bolted to the carriage and all gears In the apron are liberally proportioned for the loads they are required to carry. Positive geared feed is supplied with each lathe and the number of changes that are available is limited only by the number of change-gears obtained for use with the lathe. The regular equipment furnished with each machine includes large and small faceplates, center- and follow-rests, a countershaft and the necessary wrenches for making all adjustments.
The principal dimensions are as follows: diameter of hole through spindle, 7/8 inch; swing over ways, 12 1/8 inches; swing over compound rest, 7 ½ inches; distance between centers for 5-foot bed, 33 inches; change-gears provided for cutting 4 to 36 threads per inch; width of driving belt, 1 ¾ inch; and weight of machine with 5-foot bed, 775 pounds. |
