Abstract

353,813. Drilling-machines; shearing. FOUQUET, E., 112, Rue Jean JaurÞs, Bois Colombes, Seine, France. Dec. 3,1930, No. 36443. Convention date, Dec. 4, 1929. [Classes 83 (iii) and 83 (iv).] In a combined drilling and slotcutting machine the drill 25 is rotated from an electromotor 31 through a coupling 28 engaged with a nut 19. The shaft 1 carries an eccentric 2 which reciprocates a plunger 9 to which is removably secured a slot-cutting tool 10, cutting lip 37 co-operating with notches in a guide 14. The tool 10 and the guide 14 may be adjusted, to allow of the machine being used with a pull or thrust action by releasing screws, 11, 15. The tool 10 carries a recess 36 which allows chippings to be expelled from a cut-away portion 39 of the guide. In use, an initial hole is made by the drill 25 and the workpiece 42<1> is severed by slot-cutting when the tool 10 is inserted into the hole.
