Abstract
469,917. Milling - machines. ATTI, R. Sept. 17, 1936, No. 25336. [Class 83 (iii)] In a milling-machine for producing moulds for making golf balls, a pattern 41 and mould blank 33 are rigidly mounted together for movement about two perpendicular axes with respect to a cutter 13 and feeler 44. The cutterspindle 11 is connected to a rod 8 slidable axially in a pedestal 7 on a slide 4 which is adjustably clamped at 5 to a guideway on the machine base 1. The spindle 11 is journalled in a pedestal 6 on the slide 4, is rotated by a pulley 9 and fed axially towards the work by a hand lever 52 and a non-rotatable socket 54. The blank 33 is secured by a screw 36 in a chuck 32 secured to a spindle 31 journalled in a bracket 28 secured to a turntable 19 rotatable about a fixed pivot 20 on the base 1. The rear end of the spindle 31 carries a holder 35 to which the pattern 41 is secured by screws 42, the pattern and blank being concentric and their diametral plane 40 containing the axis of the pivot 20. In operation a feeler 44 on a standard 46 is pressed by a spring 47 against the pattern and the pattern and blank are oscillated about the axes 20, 31 whilst the feeler traverses the grooves 43 of the pattern. The cutter is fed into the work by the lever 52, the depth of cut being limited by a stop 14 on the spindle 11 engaging a collar 15 on the pedestal 6. A handle for oscillating the pattern may be attached thereto by means of a hole 51 and the feeler 44 may be held out of engagement with the pattern by deflecting the spring 47 to one side of a head 48 on the feeler, as shown in full lines in the Figure. The cutter may be fed into the work by a spring. Cuttings, catching and removing ; lubricating cutting-tools and work.-Oil is fed to the cutter 13 by means of a pump and pipe 26 and the overflow is collected in a cup-shaped top 21 of the pivot 20 and conducted through the pivot and thence by a pipe 24 to be re-circulated by the pump.
