Abstract

625,433. Drilling &c. machine details. SOC. A. B. G., and SOC. CIVILE D'ETUDE DES INVENTIONS & PROCEDES PHILIPPE. July 17, 1946, No. 21428. Convention date, Oct. 18, 1943. [Class 83 (iii)] In a drilling or like machine, in which a tool-holder 7 is movable on an overhanging arm 3 mounted on a frame 1 and in which the weight of the tool-holder is relieved from the arm 3 by a compensating device, the toolholder and compensating device are supported by a carriage 12 slidable on a girder 8 which is independent of and parallel to the arm 3. The carriage has rollers 14 running on the girder 8 and is connected to a slide 6 carrying the toolholder by means of a rotatable bush 20 and a yoke 21. A counter-weight 18 is connected to the tool-holder by a cable or chain 17 running over pulleys or sprockets 16 on the carriage and is prevented from swinging by a guide 24 connected to the carriage. The girder 8 is pivoted on the frame at 10 and a weight 19 holds it against an adjustable abutment 11. An adjustable spring-tension device may replace the counter-weight 18.
