Abstract

524,950. Indexing. THIEME, W. Feb. 10, 1939, No. 4480. Convention date, Feb. 15, 1938. [Class 83 (iii)] A universal dividing-head for milling- machines wherein the spindle 5 carries a crank 6 engageable in a perforated dividing-disc 1 has change and reducing gears for use in differential dividing and arranged to connect a wheel 8 on the spindle to a wheel 9 on the dividing disc. The change wheels are contained in a casing 16 disposed behind the dividing plate. The wheel 8 is connected through reduction gears 10 ... 14 to a spindle 15 carried in bearings 17, 18, and carrying the first change wheel 20 of a train 20, 21, 9, the last wheel being mounted on the dividing-plate 1 and the wheel 21 being mounted in a slot in a swinging member 22. For producing spiral wheels the table feed screw is connected by change gears 30 and bevel gears 26 to the casing. Screws 32 and 33 may respectively lock the dividing disc to the casing and the casing to the frame. For straight teeth with simple division both the screws 32, 33 are locked and if differential dividing is required the screw 32 is unlocked. For cutting spiral teeth with simple division only the screw 32 is un locked while both screws are unlocked if differential division is required.
