Abstract

749,974. Masonary cutters. SAUER, C. Aug. 9, 1954 [April 17, 1954], No. 23115/54. Class 124 A slot cutting machine comprises a hand operated rotary drill to which is attached a casing, extending in the longitudinal direction of the drill, containing the reduction gear for driving the cutters. As shown, a rotary drill 5 has a tubular portion attached to its front end by a shackle 4 welded to the split end of a part 1, the; other end of the part 1 being fixed by a screw thread 29 to a gear casing 2 carrying a worm 7 on the shaft 9 and a worm wheel 8 on a shaft 21. An extension 17 of the worm shaft 9 is drivingly engaged with a sleeve 18 fixed to the shaft of the drill. The shaft 21 of the worm wheel has an extension carrying a pair of cutters 27 which are partially enclosed by a cover 28. The connections between the part 1 and the drill and between the parts 1 and 2 are made in a dust-proof manner and the ends of the part 2 through which the parts 9 and 21 extend are also closed by dustproof packings.
