Abstract

631,495. Drilling-machines. SLACK & PARR, Ltd., and SLACK, H. A. June 26, 1947, No. 16889. [Class 83 (iii)] A multiple spindle head for drilling and like machines of the type in which rotation of a main drive member is transmitted by cranks to drive a number of separate drill or like spindles has one of the spindles arranged co-axial with the drive member with its crank-pin arranged in the same plane as the other crank-pins and the crank-pin associated with the main drive member. The crank 3 secured to the drive member 1 has a balance weight 21 and a crankpin 4 which is received in a bore 19 of a transmission member 5. One of the tool spindles 13 is arranged co-axial with the member 1 and has a crank-arm 14 lying in the same plane as the crank-arms 12 of the other spindles 9 and is provided with a crank-pin 15 which is received in an axial recess 16 in the crank-pin 4 of the main drive member. The driven spindles are provided with spaced sets of needle rollerbearings 17 and thrust-bearings 18.
